 # weatherreporter
 
-`weatherreporter` is a Go application for preparing human-facing weather
-reports from normalized forecast data. It builds structured briefing packages,
-runs them through `scriptorium`, and keeps inspectable artifacts under a local
-workspace.
+Weatherreporter is a Go CLI that turns normalized weather data into managed,
+human-facing Markdown reports.
+
+It provides repeatable reports with inspectable local artifacts, so operators
+can review what was collected and generated for every run.
 
 ## Quickstart
 
 ```sh
-weatherreporter generate daily --date 2026-05-29 --out ./daily.md
+weatherreporter generate today --out ./today.md
 ```
 
+Configure a Weather API endpoint first; see the
+[configuration reference](docs/config.md).

 # Weatherreporter CLI
 
-`weatherreporter` generates Markdown weather reports, runs scheduled report
-batches, and inspects previously generated artifacts.
+`weatherreporter` generates weather reports, runs report batches, and inspects
+artifacts already stored in its workspace.
 
 ## Shortest Useful Command
 
 ```sh
-weatherreporter generate daily --date 2026-05-29 --out ./daily.md
+weatherreporter generate today --out ./today.md
 ```
 
-This loads configuration, fetches weather data, writes managed workspace
-artifacts, runs `scriptorium render` as a preflight check, runs
-`scriptorium run`, and writes an extra Markdown copy to `./daily.md`.
+The command uses the configured Weather API and writes an extra Markdown copy
+at `./today.md`. See the [configuration reference](config.md) to supply the
+required Weather API endpoint.

 ```
 
-`generate` commands write briefing, data package, preflight, report, and
-metadata artifacts under the configured workspace. `generate storm` requires
-explicit event-window bounds with `--start` and `--end`.
+`weatherreporter --version` prints the version embedded in the executable.
+Tagged release binaries report their semantic version tag; ordinary local
+builds report `development`.
 
-`run morning` generates Daily Today and the 3-Day Outlook, plus Weekend Outlook
-except on Sunday. `run evening` generates the Tomorrow Planning Brief. Batch
-runs continue independent reports after a failure, print a JSON summary to
-stdout, write compact status lines to stderr, and return nonzero when any report
-failed.
+| Command | Contract |
+| --- | --- |
+| `generate daily` | Requires `--date YYYY-MM-DD`; the date is interpreted in the effective report timezone. |
+| `generate today` | Accepts an optional `--date YYYY-MM-DD`; without it, the current local date in the effective report timezone is used. |
+| `generate tomorrow` | Uses the next local civil day and accepts the common generate flags. |
+| `generate hourly` | Covers the next six hours in the effective report timezone. It does not accept `--date`, `--hours`, or `--duration`. |
+| `run morning` and `run evening` | Run their defined report batches. `--out-dir` writes extra Markdown copies; `--out` is not accepted. |
 
-`inspect` commands read existing workspace artifacts and emit JSON to stdout.
-They do not fetch weather data or invoke `scriptorium`.
+`generate` accepts the four report command names shown above. `run` accepts
+only `morning` and `evening`. Batch membership, workspace artifacts, and
+notification sequencing are described in the [operations guide](operations.md).
 
-## Flags
+## Output, Errors, And Quiet Mode
 
-- `-h`, `--help`: show help.
-- `--config PATH`: load configuration from `PATH` instead of `/usr/local/etc/weatherreporter/config.yml`.
-- `--units VALUE`: override configured Weather API units for `generate` and `run`.
-- `--tz NAME`: override configured Weather API timezone for `generate` and `run`.
-- `--out PATH`: write an extra Markdown report copy for `generate` commands.
-- `--out-dir PATH`: write extra Markdown report copies for `run morning` and `run evening`.
-- `--date YYYY-MM-DD`: optional date for `generate daily`; defaults to the current local date in the configured timezone.
-- `--start TIME`: required start time for `generate storm`.
-- `--end TIME`: required end time for `generate storm`.
-- `--limit N`: maximum records for `inspect reports`; defaults to `20`, and `0` means no limit.
+Action commands (`generate` and `run`) write a JSON summary to stdout unless
+`--quiet` is set. `run` also writes compact per-report and batch status lines
+to stderr. A pre-run error, such as an invalid flag, missing required argument,
+or configuration-load failure, produces no partial JSON summary. When an action
+fails after it has produced a result, its summary has `"status": "failed"` and
+an `error` field.
 
-Storm times accept `YYYY-MM-DDTHH:MM` in the configured timezone or RFC3339
-timestamps with explicit offsets.
+`--quiet` is supported by action commands only. It suppresses action summaries
+and routine batch status output; it does not suppress command errors.
 
-## Common Workflows
+Inspection commands always write their requested JSON value to stdout and do
+not accept `--quiet`.
 
-```sh
-weatherreporter generate tomorrow --out ./tomorrow.md
-weatherreporter generate three-day --out ./three-day.md
-weatherreporter generate weekend --out ./weekend.md
-weatherreporter generate storm --start 2026-05-29T18:00 --end 2026-05-30T06:00 --out ./storm.md
-weatherreporter run morning --out-dir ./reports
-weatherreporter run evening --out-dir ./reports
+### Generate Summary
+
+A generate summary always identifies the command, report, run, generation
+time, valid period, and status:
+
+```json
+{
+  "command": "generate",
+  "reportId": "today",
+  "reportName": "Today Report",
+  "promptId": "weather.today_generated_text",
+  "runId": "20260529T120000.000000000Z_today",
+  "status": "succeeded",
+  "generatedAt": "2026-05-29T12:00:00Z",
+  "validPeriod": {
+    "start": "2026-05-29T00:00:00-05:00",
+    "end": "2026-05-30T00:00:00-05:00"
+  }
+}
 ```
 
-## Inspection
+When available, the summary also includes `reportPath`, `metadataPath`,
+`dataPackagePath`, `preparationPath`, `executionPath`, `generatedTextRawPath`,
+`generatedTextPath`, `renderContextPath`, and `llmDebugPath`. `outputPath` is included only
+when `--out` wrote an extra copy. Distributor notification, when attempted,
+adds `notificationPath` and may add a compact `notification` object.
+
+### Run Summary And Stderr
+
+A run summary contains `command`, `batch`, `status`, `startedAt`, `finishedAt`,
+`total`, `succeeded`, `failed`, and a `reports` array. It may also contain a
+top-level `notification` object and `error`. Batch status is `failed` if any
+report or the batch notification fails.
+
+Without `--quiet`, batch status lines use this form:
+
+```text
+report=today status=succeeded output="reports/today.md"
+batch=morning total=2 succeeded=2 failed=0
+```
+
+## Flag Reference
+
+| Flag | Accepted by | Meaning |
+| --- | --- | --- |
+| `-h`, `--help` | top level | Show help. |
+| `--config PATH` | all commands | Load `PATH` instead of `/usr/local/etc/weatherreporter/config.yml`. |
+| `--units VALUE` | `generate`, `run` | Override `weather_api.units` for this command. |
+| `--tz NAME` | `generate`, `run` | Override `weather_api.timezone` for this command. |
+| `--out PATH` | every `generate` command | Write an extra Markdown report copy. |
+| `--llm-debug-dir PATH` | every `generate` and `run` command | Write requested sensitive prompt diagnostics outside the managed workspace. The path must be absolute. |
+| `--out-dir PATH` | `run morning`, `run evening` | Write extra Markdown report copies in `PATH`. |
+| `--quiet` | `generate`, `run` | Suppress action summaries and routine batch status output. |
+| `--date YYYY-MM-DD` | `generate daily`, `generate today` | Required for Daily; optional for Today. |
+| `--limit N` | `inspect reports` | Maximum runs to list. Defaults to `20`; `0` means no limit. |
+
+Distributor notification is configured through `notify.distributor`; there are
+no Distributor-specific CLI flags. See the [configuration reference](config.md).
+
+## Invocation Examples
+
+```sh
+weatherreporter generate daily --date 2026-05-29 --out ./daily.md
+weatherreporter generate today --date 2026-05-29 --out ./today.md
+weatherreporter generate hourly --out ./hourly.md
+weatherreporter generate today --llm-debug-dir /var/tmp/weatherreporter-debug
+weatherreporter run morning --out-dir ./reports --llm-debug-dir /var/tmp/weatherreporter-debug
+```
+
+## Inspection Commands
 
 ```sh

 ```
 
-`inspect reports` lists recent generated runs with artifact paths and source
-warning counts. The other inspect commands require a RunID. `inspect prior`
-returns the prior comparable snapshot metadata selected from stored metadata, or
-`null` when none exists. `inspect sources` shows source provenance and source
-warnings without dumping full weather payloads.
+| Command | JSON returned |
+| --- | --- |
+| `inspect reports` | Recent generated runs, including artifact paths and source-warning counts. |
+| `inspect metadata RUN_ID` | Persisted metadata for the run. |
+| `inspect modules RUN_ID` | The run's persisted ordered module snapshot. |
+| `inspect data-package RUN_ID` | The run's persisted prompt data package. |
+| `inspect prior RUN_ID` | Prior comparable snapshot metadata, or `null` when none exists. |
+| `inspect sources RUN_ID` | Source provenance and source warnings without full weather payloads. |
+
+Inspection is read-only: it does not collect weather data or invoke Promptkit.

 ```
 
-Use `--config PATH` to load a different file. If the default file is absent,

-fails.
+If the default file is absent, Weatherreporter uses built-in defaults. An

-1. CLI flags
-2. configuration file
-3. built-in defaults

-The implemented configuration overrides are `--units` and `--tz`. Output flags
-control report copies for the current command but do not change configuration
-files. Environment-variable configuration is not implemented.
+## Maintained Examples
 
-## Minimal Config

+  collection and generation configuration.
+- [config.yml](../examples/config.yml) is a representative production-oriented
+  configuration using synthetic endpoints and no credentials.
 
-See [examples/minimal-config.yml](../examples/minimal-config.yml).
+Both files are loaded by the configuration test suite.
+
+## Minimal Configuration
 
 ```yaml
 weather_api:
   base_url: https://weather.api.example.com/
 ```
 
-`weather_api.base_url` is required for commands that fetch weather data. Other
-fields fall back to defaults.
-
-## Production-Oriented Config
-
-See [examples/config.yml](../examples/config.yml). The example is loaded by the
-config test suite.
+`weather_api.base_url` is required for workflows that collect weather data.
+All omitted fields use their built-in defaults.
 
 ## Field Reference
 
 ### `weather_api`
 
-- `base_url`: absolute base URL for the Weather API. Required for generation and fetch workflows.
-- `timeout`: HTTP timeout duration. Default: `10s`.
-- `precision`: numeric precision query value. Default: `1`.
-- `units`: Weather API units query value. Default: `us`.
-- `timezone`: report timezone and Weather API timezone query value where supported. Default: `Chicago`.
-- `format`: Weather API response format. Must be `json`. Default: `json`.
+| Field | Default | Rules |
+| --- | --- | --- |
+| `base_url` | empty | Absolute Weather API URL. Required for collection and generation. |
+| `timeout` | `10s` | Must be greater than zero. |
+| `precision` | `0` | Must be zero or greater. Sent as the Weather API precision query value. |
+| `units` | `us` | Required Weather API units query value; `--units` overrides it for one command. |
+| `timezone` | `America/Chicago` | Required report and Weather API timezone; `--tz` overrides it for one command. |
+| `format` | `json` | Required and must be `json`. |
 
 Timezone values may be IANA names, configured aliases such as `Chicago` and
 `Stl`, US timezone abbreviations, or UTC offsets such as `-5` and `+09:30`.
 
+### `location`
+
+`location` supplies descriptive prompt context; it does not choose a Weather
+API endpoint or configure multiple forecast locations.
+
+| Field | Default |
+| --- | --- |
+| `id` | `home` |
+| `name` | `Brentwood` |
+| `region` | `St. Louis Metro` |
+
+The prompt-facing location timezone is derived from the effective
+`weather_api.timezone` after command-line overrides.
+
+### `secrets`
+
+`secrets.directory` defaults to empty, which disables secret loading. When it
+is set, every regular file directly in that directory is loaded after the file
+and command-line overrides. A file basename must match
+`[A-Za-z_][A-Za-z0-9_]*`; it becomes an environment variable name, and the
+file contents replace any existing value. One trailing LF or CRLF is removed.
+
+Missing directories, unreadable files, subdirectories, symlinks, non-regular
+files, and invalid names fail configuration loading. Put only secret values in
+this directory, never in the YAML file.
+
+### `notify.distributor`
+
+Distributor notification is disabled by default. Its fields are:
+
+| Field | Default | Rules when notification is enabled |
+| --- | --- | --- |
+| `enabled` | `false` | Activates Distributor notification validation. |
+| `endpoint` | `https://distributor.example.com` | Must be an absolute URL. |
+| `token_env` | `DISTRIBUTOR_UPLOAD_TOKEN` | Must name a valid environment variable. |
+| `timeout` | `30s` | Must be greater than zero. |
+| `failure_policy` | `error` | Must be `error`. |
+| `pipeline_id_template` | empty | Required single-report pipeline ID template. |
+| `bundle_id_template` | `weatherreporter.{location_id}.{report_id}` | Required single-report bundle ID template. |
+| `idempotency_key_template` | `{bundle_id}.{run_id}` | Required single-report idempotency-key template. |
+| `batch.enabled` | `true` | Activates batch notification validation when Distributor notification is enabled. |
+| `batch.pipeline_id_template` | `weatherreporter` | Required when batch notification is enabled. |
+| `batch.bundle_id_template` | `weatherreporter.{location_id}.{batch}` | Required when batch notification is enabled. |
+| `batch.idempotency_key_template` | `{bundle_id}.{batch_run_id}` | Required when batch notification is enabled. |
+
+The upload token is read from the environment variable named by `token_env`.
+Use `secrets.directory` when a file-backed secret is appropriate.
+
+Single-report bundle templates accept `location_id`, `report_id`, `run_id`,
+`artifact_group`, `batch_output_name`, `valid_start_date`, `valid_end_date`,
+`valid_start_time`, `valid_end_time`, `valid_start_stamp`, `valid_end_stamp`,
+Pipeline and idempotency-key templates may also use `bundle_id`. Dates use
+`YYYY-MM-DD`; times use `HHMM`; and stamps use `YYYY-MM-DDTHHMM` in the
+effective report timezone.
+
+Batch bundle and pipeline templates accept `location_id`, `batch`,
+`batch_run_id`, and `batch_started_date`; batch idempotency-key templates may
+also use `bundle_id`. `batch_started_date` is the batch start date in the
+effective report timezone.
+
+`reports.<report>.distributor.path_templates` overrides the default ordered
+Distributor paths for that report. Each rendered path must be a unique relative
+path with `/` separators. Backslashes, empty segments, `.` and `..` segments,
+`manifest.json`, and the reserved Distributor sidecar basename are rejected.
+The default paths are:
+
+| Report | Paths |
+| --- | --- |
+| `hourly` | `hourly/index.md` |
+| `daily` | `daily/{valid_start_date}/{run_id}.md`, `daily/{valid_start_date}/index.md` |
+| `today` | `daily/{valid_start_date}/{run_id}.md`, `daily/{valid_start_date}/index.md`, `today/index.md` |
+| `tomorrow` | `daily/{valid_start_date}/{run_id}.md`, `daily/{valid_start_date}/index.md`, `tomorrow/index.md` |
+
+See the [operations guide](operations.md) for notification timing, uploaded
+artifact selection, and failure handling.
+
 ### `missing_source`
 
-- `default`: missing-source behavior for optional sources. One of `error`, `warn`, or `none`. Default: `warn`.
-- `sources`: optional map of source-specific overrides, using the same policy values.
+`missing_source.default` defaults to `warn` and accepts `error`, `warn`, or
+`none`. `missing_source.sources` optionally overrides that policy by source.
+Hourly forecast data is required for generated reports. Supported optional
+source keys are `observations`, `current`, `narrative`, `alerts`, `discussion`,
+`weather_story`, and `spc_convective_outlooks`.
 
-Hourly forecast data is required for generated reports. Optional sources and
-stub source slots use the missing-source policy.
+### `promptkit`
 
-### `scriptorium`
+Promptkit configuration selects the executor and prompt/profile checks for
+every `generate` and `run` command. A top-level `scriptorium:` configuration

-  useful config for generation and fetching.
-- [examples/config.yml](../examples/config.yml): production-oriented config
-  covering implemented fields.
+Each report entry can contain:
 
-Both example files are loaded by the config test suite.
+- `deterministic_modules`: an ordered list of module IDs, or objects with `id`
+  and optional `options`.
+- `distributor.path_templates`: an optional, non-empty ordered list of
+  Distributor paths for that report.
+
+Unknown reports and modules, duplicate modules, incompatible report-module
+combinations, duplicate stanza names, invalid path templates, and invalid

+
+This is the first-read guide for people and coding agents working on
+Weatherreporter. It provides a concise repository orientation and routes each
+kind of change to its canonical documentation.
+
+Weatherreporter is a Go CLI that collects normalized weather data, derives
+deterministic report facts and module snapshots, executes Promptkit for
+single-report generated text, renders managed Markdown reports, and can upload completed
+reports through Distributor. Start with the [README](../README.md) for product
+context and the [architecture policy](policy/architecture.md) for system
+boundaries and invariants.

+# Distributor HTTP Upload Contract
+
+Weatherreporter integrates with the HTTP upload API provided by
+`gitea.maximumdirect.net/eric/distributor v0.5.0`. It submits source bundles to
+a configured pipeline and reads the resulting run status. Configuration fields
+and notification lifecycle are documented in the [configuration reference](../../config.md)
+and [operations guide](../../operations.md).
+
+## Upload Admission
+
+Weatherreporter uses an absolute HTTP(S) endpoint as a base URL. The client
+posts a gzip-compressed source bundle to:
+
+```text
+POST /v1/pipelines/<pipeline_id>/upload
+Authorization: Bearer <token>
+Content-Type: application/gzip
+Idempotency-Key: <key>
+```
+
+The authenticated token must be allowed to use the selected upload pipeline.
+A successful response is `202 Accepted` with JSON containing `run_id` and
+`status`. Acceptance means Distributor staged and validated the source bundle;
+it does not mean downstream destinations have published it.
+
+The adapter requires a pipeline ID, bundle ID, idempotency key, and at least one
+source-file mapping before calling Distributor. It reads the bearer token from
+the configured environment variable and redacts that value from errors. Request
+construction and timeout handling belong to the [Distributor adapter](../../internal/distributor-adapter.md).
+
+## Idempotency
+
+Distributor scopes idempotency to the token, pipeline ID, and key. Keys must be
+non-empty ASCII values of at most 128 bytes using letters, digits, `.`, `_`,
+`-`, and `:`. Weatherreporter always supplies a rendered key; it does not rely
+on the client library's generated-key fallback.
+
+Reusing a key for the same normalized source manifest returns the original
+accepted run. Reusing it for different content returns `409 Conflict`, which
+the adapter exposes as a Weatherreporter idempotency-conflict error. A distinct
+report or batch run therefore needs a distinct key; reuse a key only when
+retrying that same upload.
+
+## Run Status And Retention
+
+After acceptance, Weatherreporter reads:
+
+```text
+GET /runs/<run_id>
+Authorization: Bearer <token>
+```
+
+The status record provides `run_id`, `pipeline_id`, status timestamps, optional
+JSON `report`, and an `error` for failures. Statuses are `accepted`, `queued`,
+`running`, `succeeded`, and `failed`. A terminal `failed` status makes the
+notification fail; the adapter preserves the returned status details for the
+application to record.
+
+Run and idempotency records are in-memory. Completed records expire according
+to Distributor's `server.http.retention`, and a Distributor restart removes
+retained status and idempotency state. Status polling decisions and persistence
+of notification artifacts are internal orchestration behavior; see the
+[Distributor adapter](../../internal/distributor-adapter.md) and
+[application orchestration](../../internal/app-orchestration.md).

+# Distributor Source Bundle Mapping
+
+Weatherreporter uses the source-bundle format through Distributor's
+`pkg/upload.UploadFiles` helper. It does not create bundle directories or call
+`pkg/bundle` directly. The helper creates a temporary bundle, writes and
+validates `manifest.json`, archives it, and removes the temporary bundle when
+the upload call returns.
+
+## File Mappings
+
+Every mapping pairs a managed Markdown report source with one bundle-relative
+path. A single-report notification maps its one managed report to each rendered
+path configured for that report. A batch notification combines mappings for
+every included managed report and rejects duplicate bundle paths.
+
+The report source is never an `--out` copy or an arbitrary workspace scan. The
+application selects it and renders notification paths; see the [operations guide](../../operations.md)
+for the managed-upload rule and the [Distributor adapter](../../internal/distributor-adapter.md)
+for the adapter boundary.
+
+Bundle paths must be clean, relative, slash-separated paths. They cannot be
+empty or absolute, contain backslashes, empty segments, `.` or `..`, or use
+`manifest.json` or `.distributor.json` as a basename. The mapped source must be
+a regular file. File mapping order is preserved and affects the bundle digest.
+
+The bundle manifest uses schema version `1`, carries the rendered bundle ID and
+creation time, and records each mapped file's path, SHA-256 digest, and size.
+Destination routing, publication, and Distributor-managed destination state are
+not source-bundle fields.
+
+## Compatibility Reference
+
+The upstream canonical file-format contract is
+`docs/integrations/source-bundle.md` in the Distributor repository. It defines
+the complete manifest and archive format; this page records only the mapping and
+path constraints Weatherreporter relies on.

+# Distributor Upload Client Contract
+
+Weatherreporter uses `gitea.maximumdirect.net/eric/distributor/pkg/upload` at
+the pinned module version `v0.5.0`. It constructs one client per notification
+attempt and calls `UploadFiles`, followed by `Status` for the accepted run.
+
+## Client And Upload
+
+The adapter constructs the client with the configured endpoint, bearer token,
+and an HTTP client whose timeout is the configured Distributor timeout. It
+passes no custom retry options, so the pinned client's defaults apply: three
+attempts, 100 ms base delay, and one-second maximum delay.
+
+For each notification, Weatherreporter calls `UploadFiles` with:
+
+- the rendered pipeline ID;
+- the rendered bundle ID as the source manifest ID;
+- the report or batch generation time as `Created`;
+- the managed-report-to-bundle-path mappings described in the
+  [bundle mapping contract](pkg-bundle.md); and
+- a rendered idempotency key.
+
+It leaves bundle validation enabled. `UploadFiles` creates the temporary source
+bundle and sends it as a gzip-compressed tar archive; Weatherreporter does not
+call `UploadBundle` or submit prebuilt bundle roots.
+
+## Retry, Conflict, And Status
+
+The pinned upload client retries only `503 Service Unavailable` and retryable
+network failures. It does not retry successful `202` responses or other HTTP
+errors. Because every Weatherreporter request supplies an idempotency key, a
+retry keeps the same upload identity.
+
+The client decodes the accepted upload result (`run_id`, `status`) and the run
+status record. A `409` response is an upstream idempotency conflict; the
+adapter translates it to its own conflict error without exposing the token.
+
+The adapter then calls `Status` for the accepted run. A terminal `failed`
+status is a notification failure. A status lookup failure or a timeout before a
+terminal status remains attached to the otherwise accepted upload as diagnostic
+status information. Polling cadence, final failure handling, redaction, and
+notification artifact persistence are internal behavior documented in the
+[Distributor adapter](../../internal/distributor-adapter.md) and
+[application orchestration](../../internal/app-orchestration.md).
+
+## Compatibility Reference
+
+The upstream package workflow is documented in
+`docs/consumers/pkg-upload.md` in the Distributor repository. Weatherreporter
+uses only the client construction, `UploadFiles`, retry/conflict behavior, and
+`Status` operations described here.

+# Promptkit Integration
+
+Weatherreporter uses Promptkit for all generated-text reports. The four logical prompts are
+`weather.daily_generated_text`, `weather.today_generated_text`,
+`weather.tomorrow_generated_text`, and `weather.hourly_generated_text`, each at version
+`1.0.0`. Their prompt assets and generated-text JSON Schemas are embedded by
+`internal/promptassets`.
+
+Before collection, Weatherreporter inspects the exact prompt version, requires one required
+`data_package` input with content type `application/yaml`, and requires the report's JSON
+Schema output contract. It selects `promptkit.profile` when configured, otherwise the
+prompt's declared default profile. Profiles that require a direct API key are unsupported; a
+profile that reports `APIKeyEnv` requires a nonblank value in that environment variable.
+
+Execution receives the already-persisted YAML package, prepares it once, and returns structured
+JSON that Weatherreporter validates before rendering its own Markdown template. Preparation and
+execution receipts are project-owned, safe provenance records. Content-rich diagnostics are
+opt-in through `--llm-debug-dir`; see [operations](../operations.md) for retention and permissions.
+
+Prompt/profile configuration is owned by the [configuration reference](../config.md). Adapter
+construction and mapping are documented in the [Promptkit adapter internals](../internal/promptkit-adapter.md).

-# Scriptorium Integration
-
-This document describes the external Scriptorium CLI contract used by
-`weatherreporter`.
-
-## Purpose
-
-`weatherreporter` invokes Scriptorium as a subprocess to preflight prompt input
-and generate Markdown reports. This page documents the CLI surface the adapter
-uses, not the full Scriptorium product.
-
-## Commands Used
-
-Render preflight:
-
-```bash
-scriptorium render \
-  --prompt <prompt_id> \
-  --input data_package=<path> \
-  --format json
-```
-
-Report generation:
-
-```bash
-scriptorium run \
-  --prompt <prompt_id> \
-  --input data_package=<path> \
-  --out <artifact_path>
-```
-
-`weatherreporter` always passes prompt input as
-`--input data_package=<path>`. The data package is structured JSON created by
-`internal/promptinput`.
-
-## Configured Arguments
-
-The adapter can prepend configured flags before prompt-specific arguments:
-
-- `--config <path>` from `scriptorium.config_path`
-- `--profile <profile>` from `scriptorium.profile`
-
-It appends `scriptorium.extra_args` after the built-in arguments. Extra
-arguments are passed directly as argv items.
-
-`scriptorium.binary` selects the executable name or path. If unset inside the
-adapter, it falls back to `scriptorium`.
-
-## Execution Behavior
-
-The adapter runs Scriptorium without shell interpolation. Arguments are passed
-through `exec.CommandContext`.
-
-`scriptorium.timeout` limits each subprocess call when configured. Context
-cancellation or timeout returns an execution error.
-
-Stdout and stderr are captured separately. Each stream is capped at 1 MiB and
-the result records whether truncation occurred.
-
-## Results
-
-Render results include:
-
-- full argv recorded as `command`
-- stdout
-- stderr
-- exit code
-- truncation flags when applicable
-
-Run results include the same fields plus the requested output path.
-
-`weatherreporter` persists render preflight JSON when orchestration reaches the
-preflight save point. The final Markdown artifact is written by Scriptorium to
-the `--out` path.
-
-## Failure Behavior
-
-The adapter validates required request fields before starting Scriptorium:
-
-- prompt ID
-- data package path
-- output path for `run`
-
-Nonzero exits return both the captured result and an error containing the exit
-code and stderr. A `run` exit code such as `2` is still treated as an error by
-the adapter, even if Scriptorium wrote output to the requested artifact path.
-
-Subprocess start failures, context cancellation, and timeouts return errors
-without fabricating a successful result.
-
-## Security Notes
-
-- The adapter does not invoke a shell.
-- Generated artifacts, rendered prompt context, stdout, and stderr can contain
-  operationally sensitive data.
-- API keys should be provided through the Scriptorium environment or
-  Scriptorium configuration, not through `weatherreporter` CLI arguments.

 # Weather API Integration
 
-This document describes the external Weather API contract used by
-`weatherreporter`.
+Weatherreporter fetches normalized weather inputs from a configured Weather API
+base URL. This guide defines the HTTP contract the service must satisfy; it is
+not a general Weather API reference. Configuration values are defined in the
+[configuration reference](../config.md). Normalization and collection behavior
+are documented in [Weather data internals](../internal/weather-data.md) and
+[Collection internals](../internal/collect.md).
 
-## Purpose
+## Base URL And Requests
 
-`weatherreporter` uses a configured Weather API base URL to fetch normalized
-weather source data and assemble a `forecast.Bundle`. This is an integration
-contract for the project adapter, not a complete public API reference for the
-upstream service.
+`weather_api.base_url` must be an absolute URL. Weatherreporter joins each
+endpoint path to the configured base URL path, so a service hosted under a path
+prefix must keep that prefix available. Requests use `GET` and carry the
+configured timeout on every HTTP attempt.
 
-## Base URL
+Every request sends `format` and, except where noted below, `units`. The
+configured format must be `json`.
 
-`weather_api.base_url` must be an absolute URL. Adapter requests join this base
-URL with the endpoint paths listed below. Generation and explicit bundle fetches
-fail before any HTTP request when the base URL is empty or not absolute.
+Before retrieving sources, Weatherreporter warms up
+`/conditions/current` with the same `format`, `units`, and `precision` query
+parameters used for current conditions. The warmup only requires a readable
+2xx response; its body is not decoded. Failure after its internal retry budget
+stops the fetch before source requests begin.
 
-The HTTP client uses `weather_api.timeout`.
+## Endpoints And Query Parameters
+
+The adapter makes one source request for each endpoint after a successful
+warmup, subject to retry on transient failures.
+
+| Source | Endpoint | Query parameters | Availability |
+| --- | --- | --- | --- |
+| Observations | `/observations` | `format`, `units`, `precision` | Optional |

+`precision` comes from `weather_api.precision`; `tz` comes from
+`weather_api.timezone`. Weatherreporter does not call day-slice forecast or
+discussion-subsection endpoints.

-`data: null` is treated as a missing source. Missing optional sources follow the

+`isDay`, `textDescription`, `temperatureC`, `temperatureF`, `dewpointC`,
+`dewpointF`, `windSpeedKmh`, `windSpeedMph`, `windGustKmh`, `windGustMph`,
+`windDirectionDegrees`, `barometricPressurePa`, `barometricPressureInHg`,
+`visibilityMeters`, `visibilityMiles`, `relativeHumidityPercent`,
+`apparentTemperatureC`, `apparentTemperatureF`, and `presentWeather`.
 
-The adapter fetches these endpoints once per bundle:
+`/conditions/current` uses `conditionText`, `isDay`,
+`relativeHumidityPercent`, `windDirectionDegrees`, `temperatureC`,
+`temperatureF`, `apparentTemperatureC`, `apparentTemperatureF`, `dewpointC`,
+`dewpointF`, `windSpeedKmh`, and `windSpeedMph`.
 
-- `/observations`
-- `/conditions/current`
-- `/forecast/hourly`
-- `/forecast/narrative`
-- `/alerts/active`
-- `/discussion`
+### Hourly And Narrative Forecasts
 
-`weatherreporter` does not call day-slice forecast endpoints or discussion
-subsection endpoints. Report-period selection and daypart summarization happen
-inside Go after the full hourly and narrative products are fetched.
+Both forecast endpoints use run-level `locationId`, `locationName`, `issuedAt`,
+`updatedAt`, `product`, `latitude`, `longitude`, `elevationMeters`,
+`elevationFeet`, and `periods`.
 
-## Required And Optional Sources
+Each `periods` item uses `startTime`, `endTime`, `name`, `isDay`,
+`conditionCode`, `textDescription`, `temperatureC`, `temperatureF`,
+`temperatureCMin`, `temperatureFMin`, `temperatureCMax`, `temperatureFMax`,
+`dewpointC`, `dewpointF`, `windSpeedKmh`, `windSpeedMph`, `windGustKmh`,
+`windGustMph`, `windDirectionDegrees`, `barometricPressurePa`,
+`barometricPressureInHg`, `visibilityMeters`, `visibilityMiles`,
+`apparentTemperatureC`, `apparentTemperatureF`, `cloudCoverPercent`,
+`probabilityOfPrecipitationPercent`, `precipitationAmountMm`,
+`precipitationAmountIn`, `snowfallDepthMM`, `snowfallDepthIn`, `uvIndex`, and
+`relativeHumidityPercent`.
 
-Hourly forecast is required:
+### Alerts, Discussion, And Weather Story
 
-- `data: null` for `/forecast/hourly` fails the fetch.
-- an hourly forecast with no `periods` fails the fetch.
-- malformed hourly data fails the fetch.
+`/alerts/active` uses the `asOf` timestamp and keeps each item in `alerts` as
+an alert payload. Weatherreporter does not require a separate alert-item schema
+at this integration boundary.
 
-Other fetched sources are optional and follow `missing_source.default` or a
-source-specific `missing_source.sources` policy:
+`/discussion` uses `officeId`, `officeName`, `product`, `issuedAt`,
+`updatedAt`, `keyMessages`, and the `shortTerm` and `longTerm` sections. Each
+section uses `qualifier`, `text`, and `issuedAt`.
 
-- `observations` for `/observations`
-- `current` for `/conditions/current`
-- `narrative` for `/forecast/narrative`
-- `alerts` for `/alerts/active`
-- `discussion` for `/discussion`
+`/weatherstories/latest` uses `officeId`, `startTime`, `endTime`, `updatedAt`,
+`title`, `description`, `altText`, `priority`, `order`, and `downloadUrl`.
 
-The adapter also creates missing stub source records for `daily` and
-`weather_story` because those source slots exist in the internal bundle but are
-not fetched from the Weather API.
+### SPC Convective Outlooks
 
-Policy behavior:
+`/outlooks/convective` uses run-level `locationId`, `locationName`, `asOf`,
+`issuedAt`, `updatedAt`, `product`, `outlooks`, and `discussions`.
 
-- `error`: fail the fetch for that source
-- `warn`: omit the source data, add a warning, and continue
-- `none`: omit the source data and continue without a warning
+Each outlook uses `id`, `provider`, `product`, `day`, `outlookType`, `label`,
+`labelText`, `forecaster`, `severityRank`, `validFrom`, `validTo`, `issuedAt`,
+`expiresAt`, `sourceUrl`, `imageUrl`, `containsLocation`, and GeoJSON
+`geometry`. Each discussion uses `day`, `headline`, `summary`, `discussion`,
+and `updatedAt`.
 
-## Source Identity
+## Timeouts, Retries, And Failures
 
-For non-null source payloads, the adapter records:
+The configured Weather API timeout applies to each warmup and source HTTP
+attempt. Weatherreporter retries transient transport and response-read failures
+and these response statuses: `408`, `429`, `500`, `502`, `503`, and `504`.
+It does not retry other HTTP statuses, malformed envelopes, missing data, or
+payload decoding failures. A canceled context also stops an in-progress retry
+delay.
 
-- source name
-- endpoint path
-- query parameters sent
-- fetch time
-- source issue and update timestamps when present in the payload
-- SHA-256 hash of the compact raw `data` JSON
+The adapter reads at most 10 MiB from one response body. A non-2xx response,
+request construction failure, read failure, or decode failure includes endpoint
+context in its error.
 
-Warnings are recorded both on the affected source and on the bundle-level
-warnings list.
-
-## Compatibility Assumptions
-
-The adapter expects payload fields compatible with the internal forecast bundle
-types in `internal/forecast/bundle.go`, including:
-
-- observation timestamps and observation values
-- current condition values
-- forecast run metadata and `periods`
-- active alert run data
-- discussion metadata, key messages, and short/long-term sections
-
-The adapter intentionally keeps upstream transport and envelope details inside
-`internal/adapters/weatherapi`; downstream packages consume the normalized
-bundle.
+Retry counts and delays are adapter behavior rather than Weather API request
+parameters. Do not depend on a particular attempt count when implementing the
+service.

-# App Orchestration Internals
+# Application Orchestration Internals
 
-This document describes the implemented workflow coordinator in `internal/app`.
+`internal/app` owns top-level generation, batch, collection, inspection, and
+notification ordering after the CLI has parsed arguments and loaded configuration.
 
-## Purpose
+## Generation
 
-`internal/app` coordinates top-level use cases: generating one report, running
-morning or evening batches, building inspectable briefing artifacts, fetching
-weather bundles, and reading existing artifacts for inspection.
+`GenerateDetailed` resolves one of the four report definitions, initializes an
+optional debug root, and inspects the exact Promptkit prompt/profile before it
+collects weather or writes managed state. It then builds facts and modules,
+saves the YAML data package, persists preparation metadata from the executor
+callback, executes the prepared prompt, saves execution provenance and raw
+output, validates generated text, renders Markdown, and optionally copies or
+notifies from the managed report.
 
-## Inputs And Outputs
+After a completed prompt run, each successfully written downstream artifact is
+atomically added to the execution record before the corresponding metadata
+rewrite. Later failures therefore leave the original Promptkit outcome and its
+last durable set of reached paths inspectable.
 
-Inputs:
+Failure results retain all safe paths reached so far. Validation rejection
+persists raw output and execution provenance but does not render a report.
 
-- app request structs containing config, report or batch selection, clock time,
-  optional report date, optional Storm Report bounds, output paths, renderer
-  fakes, or state-store fakes
-- resolved report definitions from `internal/report`
-- forecast bundles from the Weather API adapter
-- prior briefing snapshots from `internal/state`
+## Batches
 
-Outputs:
+`RunBatchDetailed` constructs a single debug writer and uses the request's
+single executor. Before collection it inspects Today, Tomorrow, and Daily for
+morning, or Tomorrow and Daily for evening, deduplicating effective profile
+inspection. It then collects once, plans eligible Daily dates, and calls the
+same prompt-generation core sequentially for each planned report. Per-report
+notification is suppressed; a failed report does not stop later reports.
 
-- report results with briefing, data package, preflight, report, metadata,
-  prior snapshot, Recent Changes, and Scriptorium results
-- batch summaries with per-report status and artifact paths
-- inspection JSON values for reports, metadata, briefings, data packages, prior
-  snapshots, and source provenance
+Batch notification is skipped when disabled or when any report failed.
+Successful notification uses the completed managed report paths only. Batch
+items retain preparation, execution, and optional debug paths when reached.
 
-## Boundaries
+## Inspection And Boundaries
 
-- The package coordinates workflow order.
-- It does not parse CLI flags, load YAML files directly, implement HTTP calls,
-  derive forecast facts, define report periods, compare Markdown, or construct
-  Scriptorium argv.
+Inspection loads persisted state only. It does not collect weather, invoke
+Promptkit, or upload reports. The app coordinates project-owned contracts but
+does not parse flags, load YAML, implement transport, construct provider SDKs,
+or define report-period policy.
 
-## Config Fields Used
+Focused checks:
 
-- `weather_api.*` for Weather API client construction and briefing metadata
-- `scriptorium.*` for renderer construction
-- `workspace.*` for filesystem state
-- `dayparts` for daily and outlook summarization
-- `recent_change.*` for structured Recent Changes thresholds
-
-## External Adapters Used
-
-- `internal/adapters/weatherapi` for forecast bundle fetching
-- `internal/adapters/scriptorium` for render preflight and report generation
-- `internal/state` filesystem store for persisted artifacts
-
-## State Or Manifest Behavior
-
-Generation saves the briefing snapshot, data package, preflight result when
-available, rendered report, and metadata. Metadata links all managed artifact
-paths. Inspection workflows read existing state and do not fetch weather data or
-invoke Scriptorium.
-
-## Skip And Resume Behavior
-
-There is no resume workflow. Batch generation continues remaining independent
-reports after one report fails, then reports aggregate success and failure
-counts.
-
-## Failure Behavior
-
-- Resolve errors stop the requested workflow before fetching weather data.
-- Weather API or briefing errors stop that report before Scriptorium is called.
-- Render preflight runs before Scriptorium report generation.
-- If render preflight returns a result and an error, preflight JSON and metadata
-  are persisted before the error is returned.
-- If Scriptorium report generation returns an error after writing output,
-  metadata and the managed report path remain inspectable.
-- Batch failures are recorded per report and surfaced through aggregate batch
-  failure.

-This document describes the implemented briefing package boundary.
+`internal/briefing` builds typed module outputs from resolved report context,
+collected facts, and derived facts. It owns the module registry, including
+module support, fact requirements, option types, missing-data policy, builders,
+and prompt-export hooks. It does not collect data, derive periods, write a
+snapshot, construct YAML, invoke Promptkit, or render a report.
 
-## Purpose
+## Registry and construction
 
-`internal/briefing` builds structured report-specific briefing packages from
-resolved report metadata, forecast bundles, and derived forecast summaries.
-Briefings are curated inputs for prompt data packages, not rendered report
-prose.
+Every `ModuleDefinition` declares an ID, stanza name, default option value,
+required collected and derived facts, supported report IDs, missing-data
+behavior, duplicate policy, builder, and optional prompt exporter.
 
-## Inputs And Outputs
+`BuildModule` first verifies the requested module, report compatibility, and
+option shape. It then applies the declared missing-data behavior:
 
-Inputs:
+- `omit` returns no output for unavailable optional facts;
+- `error` returns the missing fact requirements; and
+- `empty` allows the builder to emit an explicit checked-empty value.
 
-- resolved report definition, generation time, timezone, and valid period
-- forecast bundle with source provenance and warnings
-- derived daily or period summaries where required
-- configured units and timezone
+Unsupported `warn` behavior, missing builders, duplicate registry IDs or
+stanza names, output ID or stanza mismatches, and exporter failures all return
+errors with module context. A successful builder gets a pass-through prompt
+value unless its definition supplies an exporter.
 
-Outputs:
+## Built value families
 
-- `briefing.Package` with common metadata and one report-specific content
-  object for Daily, 3-Day, Weekend, or Storm Report
-- optional JSON file written by `briefing.Save`
+Source-oriented builders shape report metadata, current conditions, narrative
+and hourly forecasts, alert digest, SPC outlooks and discussion, area forecast
+discussion, and weather story. Derived builders shape daily and daypart
+summaries, precipitation timing, outdoor windows, and the report-specific
+Daily, Today, and Tomorrow planning values.
 
-## Boundaries
+The module registry preserves rich values for templates and snapshots while
+curating prompt exports where needed. In particular, source warnings are a
+metadata summary, checked-empty alerts and SPC outlooks remain distinct from
+missing sources, and prompt-safe SPC values omit geometry and other
+template-only or source details. The complete module composition is in
+[module internals](module.md); fact derivation is in [fact contracts](facts.md).
 
-- This package selects and shapes weather facts for prompts.
-- It does not fetch weather data, compare prior snapshots, build
-  `data_package` files, invoke Scriptorium, or write workflow metadata.
+`area_forecast_discussion` accepts an optional typed section filter. Planning
+modules are report-specific: `daily_planning` supports Daily,
+`today_planning` supports Today, and `tomorrow_planning` supports Tomorrow.
 
-## Config Fields Used
+## Missing data and boundaries
 
-The package receives configured units and timezone from the app layer. Daypart
-configuration is consumed by `internal/forecast` before briefing builders run.
+Optional current conditions, narrative products, discussions, and weather
+stories may be omitted. Required derived modules fail when their declared facts
+are unavailable. Empty alert and outlook runs can still produce checked-empty
+modules. SPC discussion is omitted unless a retained categorical outlook meets
+the package's severity criterion and matching discussion text exists.
 
-## External Adapters Used
+Effective units, timezone, and location context arrive in `ModuleContext` from
+configuration and resolved report metadata. Field defaults are owned by
+[configuration](../config.md), and prompt-package layout is owned by
+[prompt input](prompt-input.md).

-## Skip And Resume Behavior
-
-None. Builders either return a complete briefing package or an error.

 # Changes Internals
 
-This document describes structured Recent Changes comparison.
+`internal/changes` deterministically compares a compatible prior module
+snapshot with the current snapshot. It returns compact structured changes for
+prompt input; it never reads state, finds a prior report, renders Markdown, or
+compares generated text. Snapshot construction belongs to
+[module internals](module.md), and prior-snapshot discovery belongs to
+[state internals](state.md).
 
-## Purpose
+## Comparison inputs and output
 
-`internal/changes` compares current and prior briefing packages and emits
-compact change records for prompt input data packages.
+Each comparator receives a prior snapshot, a current snapshot, and
+`Thresholds`. A `Change` has a stable type and message plus previous and
+current values where useful. Changes are sorted by type and then message, so
+the same inputs always yield the same order.
 
-## Inputs And Outputs
+Threshold values are supplied by application orchestration from the
+[Recent Changes configuration](../config.md#recent_change); this package does
+not load configuration or choose defaults. Numeric changes are emitted when
+the absolute difference meets the configured threshold. Precipitation also
+requires a change between its low, possible, likely, and high categories.
 
-Inputs:
+## Strategies
 
-- prior briefing package
-- current briefing package
-- comparison thresholds from configuration
+| Comparator | Required snapshot data | Compared values |
+| --- | --- | --- |
+| `CompareDaily` | `derived_daily_summary`, `derived_daypart_summaries` | Low and high temperature, daily precipitation probability and timing, peak gust, alerts, and aggregate indicators |
 
-Outputs:
+For daily comparison, `alert_digest` and `precip_timing` are optional: alerts
+are compared when present, and timing is compared only when both snapshots
+contain it.
 
-- ordered `changes.Change` items with type, message, previous value, and current
-  value where useful
+The application selects a comparator only after state lookup establishes a
+compatible prior snapshot. Daily, Today, and Tomorrow use the daily comparator.
+Hourly reports do not produce a Recent Changes list.
 
-## Boundaries
+## Missing data and failures
 
-- This package compares structured briefing data only.
-- It does not read filesystem state, find prior snapshots, render Markdown,
-  invoke Scriptorium, or compare generated report text.
+Required stanzas that are absent or cannot be decoded return an error with the

+eligible predecessor is not a comparison failure: the caller supplies an empty
+change list without invoking this package.

-
-## Skip And Resume Behavior
-

-

+semantics belong in [weather-data internals](weather-data.md).
+
+## Contract
+
+`Run` accepts a `context.Context` and a `Request` containing effective
+`config.Config`. It constructs the Weather API adapter from that configuration,
+calls `FetchBundle`, and returns `Result{Bundle: *weatherdata.Bundle}`.

+
+## Application Composition
+
+`internal/app` owns the narrow `Collector` interface used by workflow tests;

+orchestration rejects a nil collector result or a nil bundle before report work

+# Distributor Adapter Internals
+
+`internal/adapters/distributor` translates a local delivery request into the
+Distributor Go client's upload and status calls, then returns a local delivery
+result. The external API, authentication, and idempotency contract is owned by
+the [Distributor API guide](../integrations/distributor/api.md) and
+[Distributor bundle guide](../integrations/distributor/pkg-bundle.md).
+
+## Client construction
+
+`Client` holds the endpoint, the name of the environment variable containing
+the token, an optional timeout, and an injectable upstream-client factory.
+`New` validates its configuration before creating the adapter. For each upload,
+the adapter reads the token from the configured environment variable and builds
+the upstream client with that endpoint, token, and an HTTP client whose timeout
+matches the local positive timeout.
+
+The upstream client is an implementation dependency, not a source of
+application configuration: retry ownership, pipeline selection, path
+templates, and report rendering are defined by
+[configuration](../config.md) and [application orchestration](app-orchestration.md).
+
+## Upload translation
+
+Before calling the dependency, `Upload` validates the endpoint and token
+configuration plus the local pipeline ID, bundle ID, idempotency key, and every
+file's source and bundle paths. It maps the request as follows:
+
+| Local request | Distributor client value |
+| --- | --- |
+| Pipeline ID | Upload pipeline identifier |
+| Bundle ID | Bundle identifier |
+| Idempotency key | Upload idempotency key |
+| File source and bundle paths | Bundle file entries |
+| Creation timestamp | Bundle creation time |
+
+The call inherits the caller's context and applies the configured positive
+timeout. The adapter does not read report files, construct bundle layouts, or
+persist notification artifacts.
+
+## Status and errors
+
+An accepted upload is followed by one status request. When a timeout is
+configured, a nonterminal result is polled until `succeeded` or `failed`, or
+until the context ends. The translated `UploadResult` contains the run ID,
+status, and `RunStatus`, including pipeline ID, lifecycle timestamps, report,
+and remote error details.
+
+Status lookup or polling errors are preserved in `UploadResult.StatusError` so
+the caller can record an accepted-but-unconfirmed delivery. A terminal failed
+run returns that result and an error. Upload failures return no result. Upstream
+idempotency conflicts become the local `IdempotencyConflictError`, which adds
+endpoint, pipeline, bundle, idempotency, and file-path context while redacting
+the token.

+polling, status translation, conflict handling, and token redaction:

+# Fact Contracts Internals
+
+`internal/facts` is the deterministic boundary between a collected weather
+bundle and report-scoped facts. It preserves normalized source values and then
+selects and summarizes the values needed for one resolved report. Provider
+transport and normalized bundle semantics belong to
+[weather-data internals](weather-data.md); report identity and valid-period
+selection belong to [report registry internals](report-registry.md).
+
+## Collected facts
+
+`BuildCollected` projects a `weatherdata.Bundle` into `CollectedFacts`. It
+retains the fetched timestamp and every normalized product: observations,
+current conditions, hourly, narrative, alerts, discussion, daily, weather
+story, and convective outlook data. Source provenance and warnings are copied
+into their own slices so downstream consumers can inspect data completeness
+without treating it as an ordinary weather fact.
+
+A nil bundle produces an empty collected value. Collection itself, missing
+source policy, and source hashes are outside this package.
+
+## Report-scoped derivation
+
+`BuildDerived` requires a valid resolved period and a valid report timezone. It
+uses half-open period overlap to select hourly, narrative, daily, and alert
+data; it also derives precipitation timing. Convective outlooks are retained
+only when their valid interval overlaps the report period, with discussions
+kept for represented outlook days. Both collections are sorted deterministically.
+
+Report identity controls the summary shape:
+
+| Report family | Derived summary |
+| --- | --- |
+| Hourly | Rolling-period selections and precipitation timing; no daily or daypart summary |
+| Daily, Today, Tomorrow | One local civil-day summary and its dayparts |
+
+`DaypartSummaries` is collected from the resulting daily summaries.
+The detailed grouping, daypart-window, and alert rules are owned by
+[forecast derivation](forecast-derivation.md).
+
+## Missing data and failures
+
+Optional normalized products remain nil or yield empty selections; the package
+does not create substitute values. A present convective-outlook run with no
+matching outlooks produces non-nil empty outlook and discussion slices, while
+a missing run produces nil slices.
+
+Derivation fails for an invalid report period, invalid timezone, unsupported
+report ID, or when a requested daily summary has no hourly forecast data.
+Invalid daypart definitions surface from forecast derivation. The package does
+not access the CLI, filesystem, subprocesses, or network.

+## Verification and invariants
+
+Focused tests cover collected-fact separation, report-period selection,
+hourly behavior, daily summaries, and convective outlook selection:
+
+```sh
+go test ./internal/facts
+```
+
+Facts are derived once for a resolved report from already collected data.
+They remain reusable structured values: prompt wording, state persistence,
+prior-report comparison, and template presentation are owned elsewhere.

+Selections use `timeutil.Period` half-open overlap: a value is selected only
+when both intervals share time. `BuildDailySummary` creates one local civil
+day; `BuildPeriodDailySummaries` intersects every local civil day with the
+requested period, preserving partial first and last days.
 
-## Inputs And Outputs
+`ResolveDayparts` converts each configured name, start clock, and end clock
+into a local window. An end clock at or before its start clock wraps into the
+next civil day. The daypart and timezone defaults are defined in the
+[configuration reference](../config.md), not here.
 
-Inputs:
+## Deterministic summaries
 
-- `forecast.Bundle`
-- local date or resolved report period
-- timezone
-- configured daypart definitions
+`BuildDailySummary` requires an hourly run with at least one period. It adds
+the selected narrative periods, discussion, alert overlaps, source provenance,
+source warnings, and one `DaypartSummary` per resolved window. A daypart keeps
+its selected hourly periods and derives temperature and apparent-temperature
+ranges, timed precipitation and wind maxima, dominant and notable conditions,
+and weather indicators.
 
-Outputs:
+Indicators are deterministic checks over normalized values and condition text:
+heat, cold, and wind use package-owned numeric cutoffs; snow, ice, fog, and
+wind text are detected from the forecast description. `BuildPrecipTiming`
+sorts periods, records the maximum and first precipitation, groups contiguous
+periods at or above its package-owned probability threshold, and records
+thunder mentions.
 
-- `forecast.DailySummary` for one local civil day
-- one clipped daily summary per local day or partial day from
-  `BuildPeriodDailySummaries`
-- daypart summaries with selected hourly periods, ranges, timed maximums,
-  conditions, indicators, and alert overlaps
+Alert overlap parsing supports the normalized alert payload's available timing
+fields. Unparseable alerts and invalid intervals are ignored; valid overlaps
+are clipped to the requested period and ordered by alert start time.
 
-## Boundaries
+## Missing data and failures
 
-- This package groups, selects, and summarizes already-normalized forecast
-  data.
-- It does not perform HTTP calls, parse CLI flags, resolve report definitions,
-  compare prior snapshots, build prompt input packages, or invoke Scriptorium.
+Empty selections yield empty summary fields rather than generated prose.
+Direct daily or period-summary calls fail when their required bundle, valid
+period, hourly data, or daypart definitions are invalid. A nil location uses
+UTC when these APIs are called directly. Optional narrative, discussion, and
+alerts remain absent when their normalized products are absent.
 
-## Config Fields Used
+Forecast thresholds used for brief indicators and precipitation timing are
+implementation rules. User-configurable Recent Changes thresholds are applied
+by [changes internals](changes.md), whose defaults are documented in
+[configuration](../config.md).
 
-- `dayparts[].name`
-- `dayparts[].start`
-- `dayparts[].end`
+## Verification and invariants
 
-Threshold constants for basic indicators live in forecast code rather than
-configuration.

+summary metrics, precipitation windows, threshold helpers, and alert overlap:
 
-## External Adapters Used

-None directly. Forecast data arrives through `forecast.Bundle`.
-
-## State Or Manifest Behavior
-
-None. Source warnings and provenance from the bundle are carried into summaries
-for later metadata and briefing output.
-
-## Skip And Resume Behavior
-
-None. Missing optional source context can produce empty selections, but missing
-required hourly data fails summarization.
-
-## Failure Behavior
-
-- A nil bundle or missing hourly forecast data returns an error.
-- Invalid daypart definitions return parse errors with context.
-- Alert records without parseable RFC3339 timing are skipped.
-- Empty selected periods produce empty summaries rather than generated prose.

-## Invariants
-
-- Go owns report-period selection and meteorological summarization.
-- Weather facts come from normalized source data.
-- Outputs remain JSON-inspectable and independent of CLI, state, and adapters.
+The package preserves normalized inputs as inspectable structured values and
+never decides report identity, delivery, or presentation wording.

+# Generated Text Internals
+
+`internal/generatedtext` validates the structured prose produced for generated-
+text reports and turns validated prose plus rich module values into typed render
+contexts. It owns the catalog that pairs a generated-text report definition
+with its validator, schema ID, template ID, and context builder. The complete
+maintainer-facing context fields belong to [report templates](../templates.md).
+
+## Catalog and validation
+
+The Daily, Today, Tomorrow, and Hourly report definitions each use structured
+generated text. `LookupDefinition` rejects unknown schema or template IDs and
+unsupported schema/template pairs before the run begins. A handler validates raw JSON, returns a typed
+value and canonical normalized JSON, loads its canonical schema through
+`internal/promptassets`, builds a render context, and renders through
+`internal/reporttemplate`.
+
+Daily, Today, and Tomorrow use a day-style value with required trimmed summary
+and one or more nonblank discussion paragraphs. Hourly requires trimmed summary
+and a single trimmed discussion string. Each form permits optional trimmed
+precipitation-timing and confidence prose. Typed decoding rejects unknown JSON
+fields; no general-purpose JSON Schema engine is used at runtime.
+
+## Render contexts
+
+The catalog's report-specific builders receive briefing metadata, a rich module
+snapshot, collected facts, derived facts, and the matching validated generated
+text. They decode the module stanzas needed by the template and build typed
+Daily, Today, Tomorrow, or Hourly contexts. Context construction validates
+metadata and periods, preserves rich module values, and uses ordered slices for
+template iteration rather than maps.
+
+Optional source stanzas become nil or fallback context fields. Missing required
+stanzas, type-decoding failures, invalid metadata, or a generated-text type
+that does not match the chosen handler fail before template execution. Prompt
+packages, raw Promptkit output, state persistence, and template asset lookup
+remain outside this package.

+# Module Contract Internals
+
+`internal/module` defines the stable envelope between report composition,
+module builders, snapshots, comparisons, templates, and prompt packages. It
+does not define a report, execute a builder, or choose prompt-export policy;
+those responsibilities belong to [report registry](report-registry.md) and
+[briefing](briefing.md).
+
+## Outputs and snapshots
+
+Each `Output` has a module ID, stanza name, rich `Value`, and runtime-only
+`PromptValue`. `DataPackageValue` returns the prompt value when present and
+otherwise the rich value. This permits custom prompt exports without shrinking
+the template and inspection value.
+
+`NewSnapshot` builds the ordered `weatherreporter.modules.v1` snapshot and
+validates it. Snapshot JSON persists IDs, stanza names, and rich values only;
+`PromptValue` is deliberately excluded. `StanzaValue` decodes a named rich
+stanza into a caller-supplied type, reporting a missing stanza separately from
+a decoding error.
+
+Snapshots reject missing schema versions, empty IDs or stanza names, and
+duplicate IDs or stanza names. Output order is caller-owned and preserved.
+
+## Registered IDs and default composition
+
+The registered IDs are `metadata`, `current_conditions`,
+`narrative_forecast`, `hourly_forecast`, `derived_daily_summary`,
+`derived_daypart_summaries`, `precip_timing`, `alert_digest`,
+`spc_convective_outlooks`, `area_forecast_discussion`,
+`spc_convective_discussion`, `weather_story`, `outdoor_windows`,
+`today_planning`, `tomorrow_planning`, and `daily_planning`.
+
+The registry declares these ordered default compositions:
+
+| Report | Ordered modules |
+| --- | --- |
+| Daily | metadata, current conditions, narrative forecast, daily summary, daypart summaries, precipitation timing, alert digest, SPC outlooks, AFD (long term), SPC discussion, weather story, outdoor windows, daily planning, hourly forecast |
+| Today | metadata, current conditions, narrative forecast, daily summary, daypart summaries, precipitation timing, alert digest, SPC outlooks, AFD, SPC discussion, weather story, outdoor windows, hourly forecast, today planning |
+| Tomorrow | metadata, current conditions, narrative forecast, daily summary, daypart summaries, precipitation timing, alert digest, SPC outlooks, AFD, SPC discussion, weather story, outdoor windows, tomorrow planning, hourly forecast |
+| Hourly | metadata, current conditions, hourly forecast, precipitation timing, alert digest, SPC outlooks, AFD (key messages and short term), SPC discussion, weather story |
+
+The only non-empty default option is the AFD section selection. It accepts a
+`sections` list; omitted or empty selects all available sections. Report
+definitions may narrow it as shown above. Option shape and report compatibility
+are validated by the briefing registry.
+
+## Rich and prompt-facing values
+
+Rich values remain available to snapshots, comparisons, and render contexts.
+Briefing attaches custom prompt exports only for current conditions, hourly
+forecast, and derived daypart summaries; all other current builders use
+pass-through values. The prompt package owns how exported stanzas are grouped
+and serialized; see [prompt input](prompt-input.md).
+
+## Verification and invariants
+
+Focused tests cover snapshot validation and order, typed stanza lookup, and
+prompt-value fallback:
+
+```sh
+go test ./internal/module
+```
+
+Module IDs and stanza names are stable, every emitted output has one of each,
+and this package never imports the report registry.

 # Prompt Input Internals
 
-This document describes prompt input data package construction.
+`internal/promptinput` converts report metadata, an ordered module snapshot,
+Recent Changes, and source warnings into the YAML `data_package` consumed by
+Promptkit. It owns this package's schema, grouping, serialization, loading,
+and validation—not weather collection, module construction, path choice, or
+provider execution.
 
-## Purpose
+## Package construction
 
-`internal/promptinput` converts a structured briefing package and optional
-Recent Changes into the `data_package` JSON passed to Scriptorium prompts.
+`Build` produces `weatherreporter.data_package.v3`. It copies the run ID;
+report ID, variant, prompt ID, generation time, timezone, local current date,
+and valid period; ordered briefing stanzas; Recent Changes; and source
+warnings. A nil Recent Changes slice becomes an empty `items` list.
 
-## Inputs And Outputs
+Briefing starts as a flat snapshot order and stanza-value map. `Build` uses
+each output's `DataPackageValue`, so runtime prompt exports take precedence and
+rich values are used only as a fallback. Prompt exports are selected by the
+[briefing registry](briefing.md), while the rich-versus-prompt contract is in
+[module internals](module.md).
 
-Inputs:
+## YAML ordering and grouping
 
-- `briefing.Package`
-- optional `[]changes.Change`
+Serialization keeps `metadata` directly under `briefing`. Every other known
+stanza is placed in exactly one category, emitted in category order and in its
+original snapshot order within that category:
 
-Outputs:
+| Category | Current stanzas |
+| --- | --- |
+| `applicable_risk_products` | alert digest, SPC convective outlooks |
+| `derived_summaries` | deterministic summaries, precipitation timing, outdoor windows, and planning values |
+| `narrative_products` | narrative forecast, discussions, and weather story |
+| `raw_data` | current conditions and hourly forecast |
 
-- `promptinput.Package` containing schema version, RunID, report metadata,
-  briefing content, Recent Changes, and source warnings
-- optional JSON file written by `promptinput.Save`
+This YAML presentation does not alter the flat snapshot model. `LoadYAML`
+accepts the same category layout and reconstructs flat `Order` and `Values`,
+rejecting misplaced, duplicate, unknown, or uncategorized stanzas.
 
-## Boundaries
+## Validation and persistence
 
-- This package owns the prompt input schema and validation.
-- It does not fetch weather data, derive forecast summaries, find prior
-  snapshots, compare changes, or invoke Scriptorium.
+`Validate` requires the current schema version, run and report identifiers,
+prompt ID, generation timestamp, timezone, current local date, valid period,
+and at least one ordered briefing stanza. It rejects duplicate stanza names,
+missing values, and a missing category for every non-metadata stanza.
 
-## Config Fields Used
+`MarshalYAML` and `LoadYAML` validate their result. `Save` writes the serialized
+YAML atomically; managed workspace paths are owned by [state internals](state.md).
+Generated-text artifacts and template render contexts are later workflow
+artifacts, not members of this package.
 
-None directly. Config-derived values are already present in briefing metadata
-before this package runs.
+## Verification and invariants
 
-## External Adapters Used
+Focused tests cover construction, curated exports, category ordering, YAML
+round trips, invalid layout, validation, and atomic saves:
 
-None.

-## State Or Manifest Behavior
-
-`promptinput.Save` writes JSON atomically. Managed workspace paths are owned by
-`internal/state`.

-## Skip And Resume Behavior
-
-None. Recent Changes is always present as an `items` list and may be empty.
-
-## Failure Behavior

+from report prose.

+# Promptkit Adapter Internals

+`internal/adapters/promptkit` maps Weatherreporter's project-owned executor contract to Promptkit.
+The CLI maps `promptkit` configuration to a `PromptExecutorConfig` and constructs one executor
+per action. Promptkit dependency types do not escape the adapter.
+
+The adapter exposes exact prompt and profile inspection plus prepared execution. It maps Promptkit
+inspection values to project-owned prompt input, output-contract, profile, preparation, execution,
+validation, and optional debug values. It classifies adapter failures without copying provider secrets
+or unbounded response bodies into application errors or normal state.
+
+The app calls the executor's preparation callback before provider execution to persist safe preparation
+provenance. Completed executions are then persisted as safe execution provenance and raw generated text
+is validated by `internal/generatedtext`. The adapter does not write workspace state, render Markdown,
+choose report definitions, or send Distributor notifications.

 # Report Registry Internals
 
-This document describes report identity, valid-period resolution, batch
-membership, and comparison declarations in `internal/report`.
+`internal/report` owns the registry of report identities and the data declared
+for each one: resolution, prompt identity and version, comparison policy,
+artifact group, output-copy name, default module composition, and Distributor
+path declarations. The public command syntax is owned by the
+[CLI reference](../cli.md); configuration aliases and overrides are owned by
+the [configuration reference](../config.md).
 
-## Purpose
+## Definitions and resolution
 
-`internal/report` centralizes report definitions so report IDs, prompt IDs,
-default output names, comparison strategies, and valid periods are declared in
-one package.
+Each `Definition` declares a stable ID and display name, prompt ID, generation
+version, template and generated-text schema IDs, valid-period resolver,
+comparison strategy, artifact group, batch-copy filename, Distributor path
+templates, generation eligibility, compatible prior IDs, default modules, and
+batch eligibility flags. `Resolved` combines that definition with the valid
+period and run metadata for one invocation.
 
-## Inputs And Outputs
+| Report ID | Prompt version | Period policy | Comparison | Registry batch flag | Output copy |
+| --- | --- | --- | --- | --- | --- |
+| `daily` | `1.0.0` | Explicit local civil day | Same valid date | Dynamic Daily inclusion is app-owned | `daily.md` |

+| `hourly` | `1.0.0` | Rolling six-hour interval | Rolling window | — | `hourly.md` |
 
-Inputs:
+Each report pairs its ID and prompt version with matching template and schema
+IDs. Exact template fields and schema assets belong to [report templates](../templates.md)
+and [generated-text internals](generatedtext.md).
 
-- report ID or batch name
-- generation time
-- timezone
-- optional Daily date override
-- optional Storm Report start and end times
+All valid periods are half-open.
 
-Outputs:
+## Registry collaborators
 
-- `report.Resolved` values with definition metadata and half-open valid periods
-- `report.Metadata` values used by briefing and persisted metadata builders
+`DefaultRegistry` is the only source of the four report definitions.
+`Lookup`, `Resolve`, and report-name helpers prevent callers from duplicating
+report identity rules. Registry overrides clone a definition and replace its
+module list only after the report ID is recognized.
 
-## Boundaries
+The definition's `DistributorPathTemplates` are internal declarations consumed
+by app orchestration. Their rendered external bundle paths and compatibility
+contract are documented in the [Distributor bundle guide](../integrations/distributor/pkg-bundle.md), not repeated here.
 
-- This package defines report identity and time coverage only.
-- It does not fetch weather data, build briefings, compare snapshots, write
-  state, parse CLI flags, or invoke Scriptorium.
+`morning` and `evening` are registry-owned batch names. Registry flags declare
+fixed report eligibility; app orchestration determines data-dependent Daily
+membership and produces the actual batch plan.
 
-## Config Fields Used
+## Module composition and failures
 
-The app supplies `weather_api.timezone` as a loaded `time.Location`. Report
-output path copying uses default output names from report definitions.
+Each definition supplies an ordered `[]module.ConfigItem`; the complete
+report-to-module mapping is maintained in [module internals](module.md).
+`ArtifactGroup`, `BatchOutputName`, and comparison compatibility
+are likewise consumed by state and orchestration rather than recomputed there.
 
-## External Adapters Used
+Unknown report IDs or batch names return errors. The registry never collects
+weather data, builds modules, parses CLI flags, writes state, executes
+Promptkit, or delivers a report.
 
-None.
+## Verification and invariants
 
-## State Or Manifest Behavior
+Focused tests cover definition completeness, command and alias lookup, period
+resolution, run IDs, path declarations, composition defaults, and override
+validation:

-generation time, timezone, and valid period to later briefing and state
-metadata.
+```sh

-## Skip And Resume Behavior
-
-No resume behavior. Morning batch resolution skips Weekend Outlook on Sunday.
-
-## Failure Behavior

+# Report Template Internals
+
+`internal/reporttemplate` embeds and renders the repository's native Markdown
+templates. The current template IDs are `daily`, `today`, `tomorrow`, and
+`hourly`. The template files, partials, and complete render-context field
+reference are maintained in
+[report templates](../templates.md).
+
+## Assets and lookup
+
+The package embeds top-level templates and shared partials. `Template` returns
+the requested embedded template and fails with the requested ID when it is
+unknown or unreadable.
+
+Generated-text schemas and Promptkit definitions are owned by
+`internal/promptassets`; report-template owns Markdown source only. Report
+definitions select IDs, while [generated-text internals](generatedtext.md)
+verifies the supported schema/template pairing.
+
+## Rendering
+
+`Render` loads the top-level template, creates a `text/template` with helper
+functions and `missingkey=error`, parses the template, parses every shared
+partial, and executes the result against the typed render context. This makes
+missing context fields, bad template syntax, unreadable partials, and execution
+failures actionable with template or partial context.
+
+Top-level templates decide which shared partials they invoke. The current
+partials cover daypart forecast variants, alert digest, and precipitation
+timing. Template code receives curated typed contexts rather than raw data
+packages, and it must not reimplement weather selection or generated-text
+validation.
+
+## Boundaries and verification
+
+This package does not collect weather data, build modules, validate generated
+text, construct contexts, resolve report definitions, write state, execute
+Promptkit, or upload reports. It produces Markdown bytes for application
+orchestration to persist.
+
+Focused tests cover template lookup, rendering, partial
+behavior, missing keys, and malformed context:
+
+```sh
+go test ./internal/reporttemplate

+
+Embedded templates stay as separate files and shared fragments stay under the
+partial directory. Generated-text schemas are embedded separately by
+`internal/promptassets` and describe prose slots rather than deterministic

-## Purpose
+## Artifact Paths
 
-`internal/state` owns managed artifact paths, atomic JSON writes, persisted
-metadata, prior snapshot lookup, and read-only artifact inspection helpers.

+## Metadata And Debug Storage
 
-Outputs:
+New metadata is `weatherreporter.metadata.v2` and gains preparation and
+execution paths only after those artifacts are saved. Legacy V1 records remain
+readable; their historic preflight and generated-text-result fields are mapped
+to the corresponding preparation and execution views during inspection. New
+runs never write V1 records.
 
-- briefing snapshot JSON path
-- prompt input data package JSON path
-- render preflight JSON path
-- managed Markdown report path
-- metadata JSON path
-- prior comparable snapshot metadata
-- loaded briefing or data package
-- recent report records for inspection
+Prompt preparation and execution records are validated on both save and load.
+They require exact report/prompt identity, complete timing, internally
+consistent provenance, and status-appropriate validation or bounded classified
+errors. Completed execution provenance keeps Promptkit's run identity distinct
+from the Weatherreporter run identity.
 
-## Boundaries
+For a completed prompt run, the execution record is atomically replaced after
+each downstream artifact is saved. Its path set therefore records the raw and
+normalized generated text, render context, managed report, requested output
+copy, and notification artifact actually reached without changing the original
+Promptkit outcome.
 
-- This package owns managed workspace layout, path validation, filesystem
-  writes, and metadata reads.
-- It does not fetch weather data, derive forecasts, build prompt input content,
-  compare briefing contents, invoke Scriptorium, or parse CLI flags.
+`PromptDebugWriter` is separate from workspace state. An empty root disables
+it. An enabled absolute root is checked for safe directories and symlinks, then
+stores `preparation.json` and `execution.json` beneath
+`<root>/<report-id>/<valid-date>/<run-id>/`. Directories are `0700`; files are
+atomic `0600`. Normal state discovery does not read this root.
 
-## Config Fields Used

-- `workspace.root`
-- `workspace.snapshots_dir`
-- `workspace.reports_dir`

-`workspace.root`.

-## External Adapters Used

-## State Or Manifest Behavior
-
-Managed paths are grouped by report family and valid-period start date for JSON
-artifacts. Reports are written under the report group. Metadata is stored beside
-briefing snapshots and links briefing, data package, preflight, and report
-paths. Report listing walks metadata files under the snapshots directory.
-
-Prior snapshot lookup reads metadata and selects the latest earlier compatible

-same valid local date. 3-Day Outlook compares with prior 3-Day snapshots for
-the same valid local date. Weekend Outlook compares with prior Weekend snapshots
-for the same weekend window. Storm Report currently has no prior lookup.
-
-## Skip And Resume Behavior
-
-There is no resume workflow. Missing metadata directories return no inspection
-records or no prior snapshot rather than creating state.
-
-## Failure Behavior
-
-- Invalid workspace paths return validation errors.
-- Missing required metadata fields prevent metadata writes.
-- JSON writes use a temporary file followed by rename where practical.
-- Read and decode failures include path context.
-- Unknown RunIDs produce an actionable lookup error.

-
-- `internal/state/filesystem_test.go`
-- `internal/app/app_test.go`

-## Invariants
-
-- Managed paths stay under the configured workspace root.
-- Metadata links artifacts produced for a run.
-- Prior lookup is based on structured metadata, not rendered report text.

 # Weather Data Internals
 
-This document describes Weather API ingestion into `forecast.Bundle`.
+`internal/weatherdata` owns the normalized, wire-independent weather bundle
+that passes from collection through rendering and persistence. The Weather API
+adapter translates provider responses into these types; its request, response,
+and availability contract is documented in the
+[Weather API integration guide](../integrations/weatherapi.md).
 
-## Purpose
+## Bundle contract
 
-`internal/adapters/weatherapi` fetches normalized weather data from one
-configured Weather API endpoint and assembles the bundle consumed by forecast
-derivation and briefing builders.
+`Bundle` has a collection timestamp (`FetchedAt`), source provenance
+(`Sources`), and collection-level warnings (`Warnings`). Its product fields are
+optional so an allowed missing source can be represented without manufacturing
+weather data.
 
-## Inputs And Outputs
+| Field | Normalized product |
+| --- | --- |
+| `Observation` | Station observation |
+| `Current` | Current conditions |
+| `Hourly` | Hourly forecast periods |
+| `Narrative` | Narrative forecast |
+| `Alerts` | Active-alert check, including an explicitly empty result |
+| `Discussion` | Forecast discussion and its time-range sections |
+| `Daily` | Daily forecast periods when supplied |
+| `WeatherStory` | Latest weather story |
+| `SPCConvectiveOutlooks` | Convective outlook run, discussions, and GeoJSON geometry |
 
-Inputs:
+The bundle carries values rather than provider request details. Consumers use
+it to construct report facts and data packages; they should not infer a
+provider endpoint or retry policy from the normalized types. See
+[collection](collect.md) for assembly and
+[report templates](../templates.md) for the values exposed to authors.
 
-- `config.Config` with Weather API URL, timeout, format, units, timezone,
-  precision, and missing-source policy
-- HTTP responses using the Weather API `data` envelope
+## Source provenance
 
-Outputs:
+Every checked source is represented by a `Source` entry. The record identifies
+the source (`Name`), request location and query (`Endpoint`, `Query`), fetch
+time, provider issue and update times when available, a SHA-256 digest of the
+source data, and whether the source was unavailable (`Missing`). Its warnings
+stay with that source in addition to the bundle-level warning list.
 
-- `forecast.Bundle` with observation, current conditions, hourly forecast,
-  narrative forecast, active alerts, discussion, source records, and source
-  warnings
-- stub source records for daily forecast and weather story source slots
-- optional saved bundle JSON through app fetch helpers
+An empty product can be meaningful checked data. For example, an explicit
+empty alerts result is not missing and retains its source hash. A source is
+marked missing only when the adapter's missing-source policy treats the
+response or parsing failure as unavailable. The policy itself belongs to the
+[configuration reference](../config.md).
 
-## Boundaries
+## Warning semantics
 
-- The adapter owns HTTP calls, response-envelope handling, source hashing, and
-  decoding into internal bundle types.
-- It does not derive dayparts, resolve report periods, build briefings, compare
-  snapshots, write report state, or invoke Scriptorium.
+`SourceWarning` has a source name, stable code, severity, explanatory message,
+endpoint, and `CompletenessImpact`. When collection proceeds with a warning,
+the same warning appears in `Source.Warnings` and `Bundle.Warnings` so both
+local provenance and whole-run consumers see it. A policy that treats a missing
+source as an error returns no partial bundle.
 
-## Config Fields Used
+Warnings describe data completeness, not rendering or delivery failures.
+Those failures are recorded by the application and state layers; see
+[application orchestration](app-orchestration.md) and [state internals](state.md).
 
-- `weather_api.base_url`
-- `weather_api.timeout`
-- `weather_api.format`
-- `weather_api.units`
-- `weather_api.timezone`
-- `weather_api.precision`
-- `missing_source.default`
-- `missing_source.sources`
+## Boundaries and verification
 
-## External Adapters Used
+This package defines data shapes and has no HTTP client, configuration loader,
+filesystem access, or template behavior. Focused tests cover the normalized
+types and the Weather API adapter verifies translation into them:
 
-- Weather API HTTP service
-
-See [Weather API integration](../integrations/weatherapi.md) for the external
-contract used by this project.
-
-## State Or Manifest Behavior
-
-The adapter records source name, endpoint, query, fetch time, source timestamps
-when available, SHA-256 hash over compact raw `data` JSON, missing status, and
-source warnings. `app.FetchAndSaveBundle` can write bundle JSON atomically for
-inspection.
-
-## Skip And Resume Behavior
-
-No resume behavior. Optional missing or malformed sources may be omitted,
-warned, or treated as errors according to missing-source policy. Hourly forecast
-data is required and cannot be skipped.
-
-## Failure Behavior
-
-- Missing or invalid `weather_api.base_url` prevents client construction.
-- HTTP errors, response read failures, and envelope decode failures include
-  endpoint context.
-- Missing hourly data or hourly forecasts with no periods fail bundle fetch.
-- Optional and stub sources follow missing-source policy.
-
-## Tests
-
-Inspect:
-
-- `internal/adapters/weatherapi/client_test.go`
-- `internal/app/app_test.go`
-
-## Invariants
-
-- Weather facts come from normalized source data.
-- Full hourly and narrative products are fetched; Go owns report-period
-  selection.
-- Source provenance and warnings remain inspectable downstream.

 # Weatherreporter Operations
 
-This guide covers normal operation, generated artifacts, inspection, recovery,
-and current operational caveats. For symptom-specific diagnosis, see
+This guide covers normal operation, managed workspace state, inspection,
+recovery, and operational caveats. See the [CLI reference](cli.md) for complete
+command syntax and the [configuration reference](config.md) for fields,
+defaults, and notification templates. For symptom-based diagnosis, see
 [Troubleshooting](troubleshooting.md).
 
-## Normal Workflow
+## Normal Operation
 
-Implemented generation commands:
+After configuring a Weather API endpoint, generate one report:
 
-```text
-weatherreporter generate daily --date 2026-05-29
-weatherreporter generate tomorrow
-weatherreporter generate three-day
-weatherreporter generate weekend
-weatherreporter generate storm --start 2026-05-29T18:00 --end 2026-05-30T06:00
+```sh
+weatherreporter generate today --out ./today.md
 ```
 
-Each command resolves a report period, fetches a Weather API bundle, builds a
-briefing, builds a prompt input data package, runs `scriptorium render`, runs
-`scriptorium run`, and writes managed artifacts under the configured workspace.
-`--out PATH` writes an extra Markdown copy for the current generated report.
+A generation collects weather data, resolves the report period, builds and
+persists the module snapshot and prompt data package, records Promptkit
+preparation provenance before provider execution, then persists raw output and
+execution provenance, validates the structured generated text, and renders the
+managed Markdown report from the validated text and deterministic values.
 
-Implemented batch commands:
+The managed report and its final metadata are saved before single-report
+Distributor notification is attempted. `--out` writes an extra operator copy;
+it never changes the managed report or upload source. A successful generate
+command prints its summary to stdout unless `--quiet` is used.
 
-```text
-weatherreporter run morning
-weatherreporter run evening
+## Optional Prompt Debug Capture
+
+Use `--llm-debug-dir` only when content-rich prompt diagnostics are required:
+
+```sh
+weatherreporter generate today --llm-debug-dir /var/tmp/weatherreporter-debug
 ```
 
-`run morning` generates Daily Today and the 3-Day Outlook, plus Weekend Outlook
-except on Sunday. `run evening` generates the Tomorrow Planning Brief. Batch
-commands print a JSON summary to stdout, write compact per-report status lines
-to stderr, continue independent reports after one report fails, and return
-nonzero when any report failed. `--out-dir PATH` writes extra Markdown copies
-using report default filenames such as `daily.md`, `three-day.md`,
-`weekend.md`, and `tomorrow.md`.
+The directory must be absolute and is initialized before prompt inspection or
+weather collection. Capture files are stored outside the managed workspace,
+with restrictive permissions, under the report ID, valid date, and RunID.
+They can contain rendered prompts and generated output, so the normal metadata,
+CLI summary, and routine logs contain only the optional directory path—not
+their content. A capture-write failure stops that run before later work can
+continue.
 
-## Filesystem Layout
+Run a scheduled batch with the same configured collection:
 
-The default workspace root is `workspace`.
+```sh
+weatherreporter run morning --out-dir ./reports --llm-debug-dir /var/tmp/weatherreporter-debug
+```
+
+Each batch validates its configured prompt/profile candidates, then collects once before it plans reports. Morning runs Today, Tomorrow,
+and every eligible dated Daily Report; evening runs Tomorrow and the same
+eligible Daily Reports. Eligible Daily dates begin after tomorrow and require
+complete hourly coverage for their entire local civil day. A batch continues
+after an individual report fails and returns an aggregate failure when any
+report or batch notification fails.
+
+`--out-dir` writes extra copies such as `today.md`, `tomorrow.md`, and
+`daily-YYYY-MM-DD.md`. These copies are never upload sources. Batch report
+copies and notification behavior are summarized in the CLI result; use the
+[CLI reference](cli.md) for its exact JSON and stderr contract.
+
+## Managed Workspace
+
+The default workspace root is `workspace`. Artifact paths use the report
+definition's artifact group, the valid-period start date in the effective
+timezone, and the RunID:
 
 ```text

 ```
 
-Managed artifact filenames use the RunID, so repeated runs for the same valid
-period do not overwrite each other.
+The generated-text and render-context artifacts are written for every completed
+single-report generation.
+A report's metadata links the module snapshot, data package, preparation and
+execution receipts, managed report, generated-text artifacts, and any available single-report
+notification artifact. Batch notification artifacts are separate batch-level
+records under `notifications/batches`.
 
-## RunID And Metadata
+RunIDs begin with the UTC generation timestamp and report ID. A Daily RunID
+also contains its local valid date so multiple Daily reports in one batch have
+different managed paths. Batch notification RunIDs contain the UTC batch start
+timestamp and batch name.
 
-RunIDs are based on generation time plus report ID:
+## Distributor Notification
 
-```text
-20260529T100000.123456789Z_daily_today
-```
+When `notify.distributor.enabled` is enabled, a successful `generate`
+uploads only the managed Markdown report after final metadata has been saved.
+The extra copy from `--out` is never uploaded. A notification attempt writes
+a redacted debug artifact at
+`notifications/<artifact_group>/<YYYY-MM-DD>/distributor.<run_id>.json`; its
+path is then recorded in report metadata.
 
-Each generated report writes metadata that links:
+Batches suppress per-report notification. When both Distributor and its batch
+notification are enabled, Weatherreporter submits one multi-report upload after
+every planned report succeeds. If any report fails, it records a top-level
+`skipped` notification with reason `one or more reports failed` and does not
+call Distributor. If batch notification is disabled, a batch does not fall back
+to individual uploads.
 
-- RunID, report ID, variant, and prompt ID
-- generation time, timezone, and valid period
-- source location, source hashes, and source warnings
-- briefing snapshot path
-- prompt input data package path
-- preflight output path
-- managed Markdown report path
+A batch notification attempt writes
+`notifications/batches/<batch>/<YYYY-MM-DD>/distributor.<batch_run_id>.json`.
+A notification failure makes the batch fail but does not change successful
+individual report items into failed items. The debug artifacts contain rendered
+identifiers, managed source and bundle paths, upload and status results, and
+redacted errors; they do not contain tokens.
 
-Batch summaries include report status, error text when applicable, valid
-period, and known artifact paths for each attempted report.
+## Inspecting Stored Runs
 
-## Inspection
+Inspection is read-only: it neither collects weather data nor invokes
+Promptkit or Distributor. Start by finding a RunID:
 
-Inspection commands read existing workspace artifacts and emit JSON to stdout.
-They do not fetch weather data or run `scriptorium`.
-
-```text
+```sh
 weatherreporter inspect reports --limit 10
 weatherreporter inspect metadata RUN_ID
-weatherreporter inspect briefing RUN_ID
-weatherreporter inspect data-package RUN_ID
-weatherreporter inspect prior RUN_ID
-weatherreporter inspect sources RUN_ID
 ```
 
-Use `inspect reports` to find recent RunIDs and artifact paths. Use
-`inspect metadata` to see the artifact links recorded for a run. Use
-`inspect briefing` and `inspect data-package` to review the exact structured
-inputs used for rendering. Use `inspect prior` to see the prior comparable
-snapshot selected for Recent Changes, or `null` when none exists. Use
-`inspect sources` to review source provenance and warnings without dumping full
-weather payloads.
+| Command | Reads |
+| --- | --- |
+| `inspect reports` | Metadata files under the workspace snapshots tree. |
+| `inspect metadata RUN_ID` | Metadata located by RunID. |
+| `inspect modules RUN_ID` | The module snapshot path recorded in metadata. |
+| `inspect data-package RUN_ID` | The data-package path recorded in metadata. |
+| `inspect prior RUN_ID` | The run metadata, then compatible earlier metadata for its comparison policy. |
+| `inspect sources RUN_ID` | Source provenance and warnings in the run metadata. |
 
-## Recent Changes
+A missing snapshots directory produces no listed reports. An unknown or empty
+RunID is an error; use `inspect reports` to obtain a valid value.
 
-Recent Changes are computed from structured briefing snapshots, not rendered
-Markdown text.
-
-Daily Today and Daily Tomorrow can compare with each other when they cover the
-same valid local date. 3-Day Outlook compares with prior compatible 3-Day
-snapshots for the same valid local date. Weekend Outlook compares with prior
-compatible Weekend snapshots for the same weekend window. Storm Report currently
-leaves Recent Changes empty.
-
-When no prior comparable snapshot exists, or no configured threshold is crossed,
-`recentChanges.items` is empty.
+New runs write `weatherreporter.metadata.v2`, including preparation and
+execution references once those receipts exist. `inspect metadata` also reads
+historic V1 records; their legacy preflight and generated-text-result fields
+remain visible for compatibility, but Weatherreporter does not write them for
+new runs.
 
 ## Recovery
 
-A failed generation run may still leave useful artifacts:
+Keep the workspace when a run fails: artifacts reached before the failure
+remain available where they can be safely persisted.
 
-- If `scriptorium render` returns a result with a nonzero exit code, the
-  preflight JSON and metadata are written for inspection.
-- If `scriptorium run` exits nonzero after writing a report, the managed report
-  and metadata remain available.
-- For batch commands, inspect the stdout JSON summary first, then inspect the
-  artifact paths for each failed report.
+- A preparation failure can leave its classified receipt and metadata.
+- A report-generation failure can leave the managed report, module snapshot,
+  data package, and metadata.
+- A completed prompt validation rejection leaves raw text, an execution receipt,
+  and metadata. Later generated-text failures can also leave validated text and
+  a render-context artifact, depending on where they stopped.
+- A single-report notification failure preserves the report and final metadata,
+  including its notification artifact when it was written.
+- A batch notification failure preserves each report's artifacts and adds the
+  top-level batch notification artifact.
 
-For a bad report, start with:
-
-```text
-weatherreporter inspect metadata RUN_ID
-weatherreporter inspect sources RUN_ID
-weatherreporter inspect briefing RUN_ID
-weatherreporter inspect data-package RUN_ID
-weatherreporter inspect prior RUN_ID
-```
+Use the RunID from the action summary with the inspection commands above. For
+a batch failure, inspect the summary first, then inspect the affected report
+RunIDs or the batch notification path. Do not remove the whole workspace as a
+first response; retain it until the failure is understood.
 
 ## Operational Caveats
 
-- The application uses one configured Weather API endpoint.
-- The application writes local filesystem state only.
-- The application does not implement resume, cleanup, archive, remote storage,
-  daemon operation, or automatic storm monitoring.
-- Generated reports and Scriptorium stderr can contain sensitive operational
-  context. Store workspace artifacts with appropriate filesystem permissions.
+- Workspace files and generated reports can contain
+  sensitive operational context. Set appropriate filesystem permissions and do
+  not publish them unintentionally.
+- Weatherreporter uses one configured Weather API endpoint and local workspace
+  state.

-# Architecture
+# Architecture Policy
 
-This document defines the development principles for this Go project. It is inward-facing: developers and LLM coding agents should use it to preserve the project’s shape, boundaries, and invariants as the code evolves.
+## Purpose
 
-## weatherreporter
-`weatherreporter` is a deterministic weather briefing and report-preparation application. It consumes normalized weather data from the internal weatherfeeder-backed API, derives report-specific briefing packages, compares those packages against prior snapshots, and invokes an external prompt runner to produce human-facing reports.
+This policy defines Weatherreporter's system shape, ownership, dependency direction,
+and safety invariants. The [development guide](../development.md) owns the
+package inventory; focused documents in `docs/internal/` own implementation detail.
 
-The application should keep meteorological data selection, daypart grouping, threshold detection, forecast-period resolution, and recent-change comparison inside Go domain packages. LLM prompts should receive curated briefing packages rather than raw unbounded source payloads wherever practical.
+## System Shape
 
-Report types must be defined through a registry or equivalent mechanism. Each report definition should declare its report ID, prompt ID, valid-period resolver, briefing builder, comparison strategy, and output naming behavior. Avoid scattering report-type conditionals across CLI and orchestration code.
+Weatherreporter is a deterministic weather-report CLI. It collects normalized
+weather data, derives facts and modules, builds a curated YAML data package,
+compares prior snapshots, executes exact-version Promptkit prompts, validates
+structured generated prose, and renders repository-owned Markdown. Completed
+managed Markdown may be uploaded through Distributor.
 
-Generated reports must be associated with explicit metadata, including report type, location, generation time, valid period, source product timestamps or hashes, briefing snapshot path, and output path. Recent Changes must be based on structured snapshot comparison rather than comparison of rendered Markdown report text.
+The supported report products are Daily, Today, Tomorrow, and Hourly. A batch
+collects once, validates its complete candidate prompt/profile set before
+collection, then executes planned reports sequentially with one executor. It
+continues after independent report failures and sends a batch notification only
+after every planned report succeeds.
 
-`scriptorium` is an external adapter, not domain logic. Subprocess execution must be isolated under `internal/adapters/scriptorium`, use context-aware execution, avoid shell interpolation, capture actionable stderr, and keep scriptorium-specific flags from leaking into domain packages.
+## Ownership And Boundaries
 
-## Project Shape
+- `internal/cli` owns command parsing, help, summaries, and one executor
+  construction per action.
+- `internal/config` owns defaults, loading, validation, and secret loading.
+- `internal/app` owns workflow order, partial results, and notification
+  coordination through project-owned contracts.
+- Deterministic domain packages own weather derivation, report periods, modules,
+  generated-text validation, and template contexts.
+- `internal/adapters/weatherapi`, `internal/adapters/promptkit`, and
+  `internal/adapters/distributor` own their external dependency mechanics.
+- `internal/state` owns workspace paths, V2 metadata, atomic persistence, and
+  read-only inspection.
 
-Default to a small, explicit, dependency-light Go application. Keep the design modular enough to test and change safely, but do not add abstraction unless it protects a real boundary or enables a real extension point.
+Dependency-specific Promptkit types remain inside its adapter. The application
+does not parse flags, construct provider clients, or render provider output
+directly.
 
-Business/domain logic should live outside CLI, transport, and external-adapter packages.
+## Prompt Execution Invariants
 
-## Dependency Policy
+- Prompts receive curated module packages, never unbounded raw weather payloads.
+- Every execution inspects the exact prompt version and output contract before
+  collection. The selected profile is configured explicitly or declared by the
+  prompt; unsupported direct-key profiles and missing reported credentials fail
+  before collection.
+- Prepared execution persists safe preparation provenance before provider work.
+  Completed execution persists safe execution provenance; raw output is
+  validated before template rendering.
+- Generated text fills defined prose slots only. Deterministic facts remain
+  authoritative and repository-owned templates produce all managed Markdown.
+- Sensitive rendered prompts, schemas, input bodies, provider endpoints, and
+  credentials never enter normal metadata, summaries, logs, or workspace
+  artifacts. They are written only to an explicit secure debug root when
+  requested.
 
-Prefer the Go standard library where practical.
+## State, Notification, And Testing Invariants
 
-Use external dependencies only when justified by correctness, security, interoperability, or substantial complexity reduction. Good reasons include complex security-sensitive behavior, such as HTML sanitization, or widely used de facto standards, such as YAML parsing.
+- Managed writes are atomic where practical and stay beneath the configured
+  workspace root. Reached artifacts remain inspectable after later failures.
+- New records use `weatherreporter.metadata.v2`; V1 records remain readable for
+  inspection compatibility.
+- Distributor uploads use only the managed Markdown report, never output copies
+  or workspace scans. Notification follows report and final metadata success.
+- Default tests are deterministic, offline, and use Promptkit/provider fakes
+  rather than live provider calls. See the [testing policy](testing.md).
 
-Avoid dependencies for small conveniences. Do not let external dependency types leak across internal package boundaries unless the dependency is itself the explicit public contract of that package.
+## Non-Goals
 
-## Package Layout
-
-Use this layout unless the project has a documented reason to differ:
-
-- `internal/app`: application orchestration and top-level use cases.
-- `internal/cli`: CLI command definitions, flags, argument parsing, and command wiring.
-- `internal/config`: configuration structs, defaults, loading, precedence, and validation.
-- `internal/adapters/<name>`: adapters for external CLIs, APIs, databases, object stores, or libraries.
-- `internal/api`: HTTP API handlers and request/response types, when the application exposes an HTTP API.
-- `internal/transport/http`: HTTP client code, when the application calls HTTP services.
-
-Package-private implementation constants may live near the package that owns them, preferably in `constants.go` when useful.
-
-## Configuration
-
-Centralize configuration loading, processing, precedence, defaults, and validation in `internal/config`.
-
-The goal is to make configuration discoverable and avoid implicit or hidden operational values. User-visible defaults and cross-package operational defaults should be defined in `internal/config/defaults.go`.
-
-Configuration precedence is:
-
-1. CLI flags
-2. configuration file
-3. built-in defaults
-
-Prefer YAML configuration unless the project has a strong reason to use another format. Config files should be discovered at `/usr/local/etc/<app_name>/config.yml`, with a CLI override via `--config`.
-
-Configuration files should not contain raw secrets unless the application is explicitly designed for that. Prefer environment variables or secret files for secrets.
-
-## Adapters and External Integrations
-
-Use a hexagonal architecture style for external integrations.
-
-External adapters belong under `internal/adapters/<name>`. If an adapter uses an external dependency, that dependency’s interface must not leak outside the adapter package. Other packages should interact only with the adapter’s API, so the dependency can be swapped, upgraded, or removed without touching unrelated code.
-
-Adapters should be thin. Domain decisions belong in application/domain packages, not inside adapter glue.
-
-## Components and Registries
-
-When the application has major workflow components, each component should live
-near the package that owns its contract and have explicit inputs and outputs.
-
-The orchestrator should compose components in an explicit order using a default
-sequence, dependency graph, or documented orchestration rule.
-
-If users can select components, validators, renderers, or adapters, selection
-should go through a registry or equivalent mechanism rather than scattered
-conditionals.
-
-## Embedded Assets
-
-Store embedded JSON schemas, Markdown prompts, templates, and similar assets as separate files, not inline string literals, unless there is a strong reason otherwise.
-
-## Errors and Logging
-
-Errors should be actionable and preserve context. Wrap errors with operation and path/resource context. CLI code should convert internal errors into concise user-facing messages.
-
-Errors and logs must not expose secrets.
-
-Use structured logging where practical. Logs should describe operations, paths, external calls, retries, and failure causes, but should not include large user data by default.
-
-## Context, Timeouts, and Cancellation
-
-Long-running operations should accept `context.Context`. External calls,
-subprocesses, HTTP requests, storage operations, and multi-step workflows should
-respect cancellation and timeouts.
-
-## State, Files, and Safety
-
-If the application writes durable state, writes should be atomic where
-practical. Multi-step workflows should preserve enough state to support
-inspection and retry diagnosis after failure.
-
-Code that deletes, moves, or overwrites files must use narrow, explicit paths. Avoid broad parent-directory operations. Cleanup that can cause data loss must be opt-in.
-
-## Testing
-
-Core logic should be testable without real external services. Use fakes, fixtures, or local test doubles for adapters where practical.
-
-Config examples should be load-tested. Important CLI workflows should have
-parser or command tests. Component contracts should have focused tests that do
-not require running the full application unless end-to-end coverage is
-intentional.
-
-## Documentation
-
-Documentation should follow the project documentation policy. Keep user docs focused on implemented behavior. Put future, planned, or aspirational work only under `docs/roadmap/`.
-
-When changing architecture, config, CLI behavior, adapters, or component
-contracts, update the relevant docs and examples in the same change.
+Weatherreporter is not a weather-data ingestion service, general LLM
+orchestration framework, plugin platform, HTTP service, multi-user job system,
+or a replacement for Promptkit or Distributor.

-# Development Policy
-
-This document is the contributor workflow policy for `weatherreporter`.
-Developers and LLM coding agents should use it with
-`docs/policy/architecture.md` and `docs/policy/documentation.md`.
-
-## Repository Layout
-
-- `cmd/weatherreporter`: binary entry point.
-- `internal/app`: orchestration for generation, batches, fetch helpers, and
-  inspection.
-- `internal/cli`: command parsing, flag handling, help text, and JSON output.
-- `internal/config`: configuration structs, defaults, loading, overrides, and
-  validation.
-- `internal/adapters/weatherapi`: Weather API HTTP adapter.
-- `internal/adapters/scriptorium`: Scriptorium subprocess adapter.
-- `internal/forecast`: normalized bundle types and deterministic forecast
-  derivation.
-- `internal/report`: report definitions, valid periods, batches, output names,
-  and comparison declarations.
-- `internal/briefing`: report-specific briefing package builders.
-- `internal/changes`: structured Recent Changes comparison.
-- `internal/promptinput`: Scriptorium `data_package` construction and
-  validation.
-- `internal/state`: filesystem paths, atomic JSON writes, metadata, lookup, and
-  inspection support.
-- `internal/timeutil`: clock, date, timezone, and period helpers.
-- `docs`: user, operator, developer, integration, internal, policy, and roadmap
-  documentation.
-- `examples`: maintained copyable examples.
-
-## Local Validation
-
-Use focused checks while editing and broader checks before committing:
-
-```bash
-go test ./...
-go run ./cmd/weatherreporter --help
-git diff --check
-```
-
-Useful focused checks:
-
-```bash
-go test ./internal/cli ./internal/config
-go test ./internal/app ./internal/state
-go test ./internal/adapters/weatherapi ./internal/adapters/scriptorium
-go test ./internal/forecast ./internal/report ./internal/briefing ./internal/changes ./internal/promptinput
-```
-
-Run `gofmt -w` on changed Go files before committing.
-
-## Coding Conventions
-
-- Keep domain logic out of `cmd`, `internal/cli`, and adapter packages.
-- Prefer small explicit structs and functions over broad framework-style
-  abstractions.
-- Keep package APIs narrow and named around implemented behavior.
-- Return errors with operation, path, endpoint, report, or RunID context.
-- Do not log or expose secrets.
-- Use `context.Context` for external calls, subprocesses, and orchestrated
-  workflows that may be canceled.
-- Use atomic writes for durable JSON artifacts where practical.
-- Keep report selection and prompt IDs centralized in `internal/report`.
-- Keep Scriptorium argv construction inside `internal/adapters/scriptorium`.
-- Keep Weather API transport and envelope handling inside
-  `internal/adapters/weatherapi`.
-
-## Dependency Policy
-
-Prefer the Go standard library. Add dependencies only when they materially
-improve correctness, interoperability, security, or maintainability.
-
-Current external dependency:
-
-- `gopkg.in/yaml.v3` for YAML configuration parsing.
-
-When adding a dependency:
-
-- explain why the standard library is not enough;
-- keep dependency types from leaking across unrelated package boundaries;
-- add tests for the behavior the dependency supports;
-- update this policy if the dependency becomes part of contributor workflow.
-
-## Configuration Changes
-
-Configuration is owned by `internal/config`.
-
-When adding or changing a field:
-
-- update `Config` and the nested config struct in `config.go`;
-- add or adjust defaults in `defaults.go` when the field has a safe default;
-- update loading or CLI override behavior in `load.go` only when needed;
-- validate required values and accepted ranges in `validate.go`;
-- add or update config tests;
-- update `docs/config.md` and maintained examples when the field is user
-  visible;
-- keep secrets out of example config files.
-
-Configuration precedence is:
-
-1. CLI overrides supported by `config.LoadOptions`;
-2. configuration file values;
-3. built-in defaults.
-
-The default config path is `/usr/local/etc/weatherreporter/config.yml`.
-
-## CLI Changes
-
-The CLI is owned by `internal/cli`.
-
-When adding or changing a command or flag:
-
-- update help text and parser behavior together;
-- convert parsed values into app-layer request structs;
-- keep domain decisions in `internal/app` or domain packages;
-- add parser or command tests in `internal/cli`;
-- update `docs/cli.md`;
-- update `docs/operations.md` or `docs/troubleshooting.md` when behavior affects
-  operators.
-
-CLI commands should return concise actionable errors and avoid printing partial
-JSON when command construction fails.
-
-## Components And Adapters
-
-Use existing package boundaries before adding a package.
-
-Add a new internal component only when it owns a distinct implemented contract.
-Define its inputs, outputs, state behavior, failure behavior, tests, and
-invariants in `docs/internal/`.
-
-Adapters should stay thin:
-
-- HTTP adapters own transport, request construction, envelope handling, and
-  decode boundaries.
-- subprocess adapters own argv construction, timeout handling, stdout/stderr
-  capture, and exit-code interpretation.
-- adapter packages should not own report selection, forecast summarization,
-  Recent Changes, or prompt input schema decisions.
-
-When an external contract changes, update the matching file under
-`docs/integrations/`.
-
-## Tests
-
-Core tests must not require live Weather API or Scriptorium services.
-
-Preferred test patterns:
-
-- fake command runners for subprocess behavior;
-- `httptest.Server` for Weather API behavior;
-- filesystem temp directories for state behavior;
-- deterministic clocks for report periods and RunIDs;
-- table tests for config validation, CLI parsing, period resolution, and
-  threshold behavior.
-
-Add focused tests near the package that owns the behavior. Use app-level tests
-for workflow ordering, persistence, and cross-package contracts.
-
-## Examples
-
-Examples under `examples/` must be real, maintained, and free of secrets.
-
-When updating examples:
-
-- use implemented config fields only;
-- avoid private endpoints and credentials;
-- keep comments short and operationally useful;
-- add or update validation coverage when a new example file is introduced;
-- link maintained examples from `docs/config.md`.
-
-Do not add generated report examples unless they can be kept current without
-live external services.
-
-## Documentation Checklist
-
-Documentation updates are part of behavior changes.
-
-Update:
-
-- `README.md` for project orientation or quickstart changes;
-- `docs/cli.md` for command and flag changes;
-- `docs/config.md` for config fields, defaults, and precedence changes;
-- `docs/operations.md` for state, artifact, batch, inspection, and recovery
-  behavior;
-- `docs/troubleshooting.md` for recurring operator-facing failure modes;
-- `docs/internal/` for component contracts and invariants;
-- `docs/integrations/` for external Weather API or Scriptorium contract changes;
-- `docs/roadmap/` only for unimplemented or deferred work.
-
-Non-roadmap docs must describe implemented behavior only.

-# Go Project Documentation Policy
+# Documentation Policy
 
 ## Purpose
 
-Project documentation must help four audiences:
-
-1. users who need to run the application;
-2. administrators/operators who need to configure and operate it;
-3. developers who need to understand and change it safely;
-4. LLM coding agents that need clear scope, boundaries, and invariants.
-
-Docs should be accurate, concise, task-oriented, and organized by audience. Prefer links to canonical docs over repetition.
+This policy assigns each Weatherreporter documentation topic to one canonical
+owner. Its goal is to keep documentation accurate, concise, discoverable, and
+resistant to drift for users, operators, developers, integrators, maintainers,
+and coding agents.
 
 ## Core Rules
 
-### 1. Keep docs concise
-
-Each document should cover a defined scope and only the essentials for that scope.
-
-Avoid:
-- long background explanations;
-- repeated reference material;
-- implementation detail in user-facing docs;
-- aspirational language outside roadmap docs;
-- verbose examples where one minimal example is clearer.
-
-### 2. Document only implemented behavior outside roadmap files
-
-Unimplemented, planned, aspirational, experimental, or future work may be described only under:
-
-- `docs/roadmap/`
-
-No other documentation file, including `README.md`, should describe code, features, modules, stages, commands, config fields, or behaviors that do not currently exist.
-
-If a feature is partial, non-roadmap docs may describe only the implemented portion and its current boundary.
-
-### 3. Use canonical homes
-
-Each type of information should have one canonical location.
-
-Canonical homes:
-
-- project purpose and quickstart: `README.md`
-- development principles: `docs/policy/architecture.md`
-- configuration reference: `docs/config.md`
-- CLI reference: `docs/cli.md`
-- operations and recovery: `docs/operations.md`
-- troubleshooting: `docs/troubleshooting.md`
-- implemented internals: `docs/internal/`
-- future work: `docs/roadmap/`
-- contributor workflow: `docs/policy/development.md`
-- copyable examples: `examples/`
-
-Other files should summarize briefly and link to the canonical source.
-
-### 4. Keep examples real
-
-Examples should be valid, maintained, and free of secrets.
-
-Where practical:
-- example configs should load successfully;
-- example commands should match real CLI syntax;
-- important examples should be covered by tests.
-

-## Required Documents
-
-### README.md
-
-**Audience:** users, administrators, operators
-
-The README is the outward-facing project orientation page.
-
-It should include, in order:
-
-1. concise description;
-2. elevator pitch;
-3. shortest useful command or usage example;
-4. links to targeted docs.
-
-The README should be short. It is not a manual.
-
-The “shortest useful command” means the simplest command that performs the project’s core use case. (It does not mean `app --help`.)
-
-### docs/policy/architecture.md
-
-**Audience:** developers, LLM coding agents
-
-`docs/policy/architecture.md` is required for every project.
-
-It is an inward-facing development policy document. It should describe how the project is intended to be built and changed.
-
-It should include:
-
-- project shape;
-- core design principles;
-- package and boundary philosophy;
-- state/persistence philosophy, if applicable;
-- external integration philosophy, if applicable;
-- error-handling and logging principles;
-- testing expectations;
-- documentation expectations;

-
-The full configuration reference should be canonical.
-
-### docs/cli.md
-
-**Audience:** users, administrators, operators
-
-Required for CLI applications.
-
-It should include, in order:
-
-1. shortest useful command;
-2. command overview;
-3. complete flag reference;
-4. common workflows;
-5. diagnostic or recovery commands, if applicable.
-
-Explain when commands are useful, not just their syntax.
-
-### docs/operations.md
-
-**Audience:** administrators, operators
-
-Required for applications that maintain state, support resume behavior, run multiple stages, write durable artifacts, use remote storage, or require recovery procedures.
-
-It should cover:
-
-- normal workflow;
-- filesystem layout;
-- remote storage layout, if applicable;
-- logs and manifests;
-- resume/retry behavior;
-- cleanup behavior;
-- archive/backup behavior;
-- safe recovery procedures;
-- operational caveats.
-
-### docs/troubleshooting.md
-
-**Audience:** administrators, operators
-
-Recommended once recurring failure modes exist.
-
-Each entry should include:
-
-- symptom;
-- likely cause;
-- diagnostic command or inspection step;
-- safe fix;
-- relevant links.
-
-### docs/internal/
-
-**Audience:** developers, LLM coding agents
-
-Required for modular, staged, service-oriented, or orchestration projects.
-
-This directory describes implemented internal components. It is not the roadmap.
-
-Use one file per major component where useful.
-
-Each component doc should include:
-
-1. purpose;
-2. inputs and outputs;
-3. boundaries;
-4. config fields used;
-5. external adapters used;
-6. state or manifest behavior, if applicable;
-7. skip/resume behavior, if applicable;
-8. failure behavior;
-9. tests to inspect before changing;
-10. architectural invariants.
-
-### docs/roadmap/
-
-**Audience:** maintainers, developers, LLM coding agents
-
-This is the only place for planned, future, aspirational, experimental, or unimplemented work.
-
-Roadmap docs should clearly distinguish:
-
-- proposed work;
-- accepted plans;
-- deferred ideas;
-- rejected ideas;
-- implementation prompts or task breakdowns, if useful.
-
-Roadmap docs should not be confused with current behavior.
-
-### docs/integrations/
-
-**Audience:** developers, LLM coding agents
-
-Required for projects that depend on external CLIs, APIs, services, protocols, or file formats where the integration contract is important to maintain.
-
-This directory contains concise, versioned reference notes for external integration contracts. It should document only the parts of the external system that this project actually uses.
-
-Use one file per integration where useful.
-
-## Examples Directory
-
-Projects with non-trivial configuration or workflows should include `examples/`.
-
-Useful examples include:
-
-- minimal working config;
-- production-oriented config;
-- full annotated config;
-- local development config;
-- remote/object-storage config;
-- minimal session/input file.
-
-Examples should be valid, maintained, tested when practical, and linked from relevant docs.
-
-## Security and Privacy
-
-Docs and examples must not include:
-
-- real API keys;
-- tokens;
-- passwords;
-- private keys;
-- private environment dumps;
-- sensitive user data;
-- raw private transcripts;
-- private infrastructure details unless intentionally public.
-
-Document secret-handling mechanisms, not actual secret values.
-
-## Maintenance Rules
-
-When docs change, verify the affected behavior.
-
-Where practical:
-
-- load example config files in tests;
-- test CLI examples or command parser behavior;
-- validate documented flags against real flags;
-- remove stale references;
-- update links after renames;
-- keep roadmap content out of non-roadmap docs.
-
-If documentation and code disagree, fix the documentation and/or open a roadmap item; do not leave aspirational behavior in current-behavior docs.
-
-Documentation is complete only when it matches the current code.
-
-## Documentation Change Checklist
-
-Before merging documentation changes, verify:
-
-- README is concise and orientation-focused.
-- `docs/policy/architecture.md` describes development principles.
-- Future work appears only under `docs/roadmap/`.
-- User-facing docs avoid unnecessary internals.
-- Developer-facing docs preserve boundaries and invariants.
-- Config examples match the schema.
-- CLI examples match real commands and flags.
-- Defaults appear in the canonical config reference.
-- No secrets or private data are included.
-- Links are accurate.
+### One Canonical Documentation Owner
+
+Each authoritative fact belongs in one canonical document or documentation
+area. A non-owning document may give a short, stable summary for orientation,
+but it must link to the canonical owner instead of maintaining a second
+definition.
+
+Volatile details include commands, flags, configuration fields and defaults,
+report and module IDs, schemas, file names, paths, status and exit behavior,
+retry behavior, and runtime guarantees. If readers could reasonably treat a
+statement as a contract, its exact documentation belongs with the owner named
+in this policy.
+
+Executable sources of truth and documentation owners serve different purposes.
+Code, schemas, and embedded assets determine runtime behavior. The canonical
+document owns the corresponding explanation or reference for readers. Both may
+necessarily express the same contract, but other documentation should summarize
+and link rather than create another complete reference. When implementation and
+documentation disagree, verify the intended behavior and update them together.
+
+### Current State, Decisions, And Future Work
+
+Outside `docs/roadmap/`, documentation describes implemented behavior only.
+Partial features may be described only to their implemented boundary.
+
+An accepted architecture decision may describe an approved direction before it
+is implemented, but acceptance is not evidence that the behavior exists.
+Current-state documents change when the implementation lands. Temporary
+roadmaps own future work, sequencing, and implementation status; they do not
+replace durable policies, decisions, or current contracts.
+
+### Audience And Detail
+
+Write for the document's stated audience and include only the detail needed for
+its owned topic. User and operator documentation should not expose incidental
+implementation detail. Developer documentation should link to user-facing and
+external contracts instead of restating them.
+
+### Links
+
+Use descriptive link text and repository-relative links for repository
+documents. Link to the canonical owner rather than to a duplicate summary.
+Check every added or changed link, and repair or remove links when their target
+moves or is retired.
+
+### Examples And Code Fences
+
+Complete copyable files belong in `examples/` when maintained examples exist.
+Documentation may use the smallest illustrative snippet needed for its owned
+topic, but should link to a maintained example instead of embedding a second
+complete copy.
+
+Examples must be valid, secret-free, and tested where practical. Commands,
+flags, configuration, imports, and Go snippets must match implemented behavior.
+Use a language tag on fenced code blocks, and identify fragments that are
+illustrative rather than directly runnable.
+
+### Security And Privacy
+
+Documentation and examples must not contain real credentials, private keys,
+private environment dumps, sensitive source material, or private
+infrastructure details unless intentionally public. Document secret-handling
+mechanisms, not secret values.
+

+| Temporary feature roadmaps | `docs/roadmap/`, while planned work needs coordination | Proposed, accepted, deferred, or rejected work; sequencing; gates; implementation status; and task breakdowns. | Implemented behavior reference and durable decision rationale. |
+| Complete copyable artifacts | `examples/` | Maintained configuration and other files intended to be copied or run. | Field-by-field reference, command reference, and prose explanation. |
+
+Conditional owners do not require placeholder files or directories. If
+Weatherreporter introduces a new public API, consumer interface, release
+process, or other durable documentation responsibility, update this policy to
+assign its canonical owner when that responsibility is introduced.
+
+## Boundary Rules
+
+### Orientation, Architecture, And Internals
+
+The README owns product orientation. The development policy routes contributors
+and owns the concise current package inventory. Architecture owns normative
+structure and invariants. Focused internal documents own implementation
+behavior. These documents may link to one another but must not maintain
+parallel package or behavior references.
+
+### Commands, Configuration, Operations, And Troubleshooting
+
+CLI documentation answers how to invoke Weatherreporter and what its command
+interface does. Configuration documentation answers what settings mean.
+Operations answers what happens to runtime state and how to operate or recover
+the application. Troubleshooting starts from a symptom and leads to diagnosis
+and a safe fix.
+
+When a workflow crosses these topics, place the complete procedure with the
+document that owns the task and link to the other contracts. Do not duplicate
+complete flag, field, or path references to make a workflow self-contained.
+
+### Templates, Integrations, And Implementation
+
+Template documentation defines the maintainer-facing rendering surface.
+Integration documentation defines externally observable shapes, logical paths,
+protocols, and compatibility behavior. Internal documentation explains how
+Weatherreporter produces, transforms, or consumes those contracts.
+
+Internal documents may name a command, field, template value, path, or protocol
+to identify a dependency, but must link to its canonical documentation for the
+complete definition.
+
+### Release Procedure And Release Notes
+
+The release procedure owns how a maintainer prepares, publishes, verifies, and
+recovers from a Weatherreporter release. Release notes under `docs/releases/`
+own the concise historical summary for one version and are the checked-in
+source for its generated Gitea release body.
+
+Release notes are not current-state reference documents. They may summarize
+what changed and link to durable documentation, but they must not become a
+second command, configuration, operations, integration, architecture, or
+internal reference. Correct the applicable canonical owner in the same change
+when a release changes an implemented contract.
+
+The release note at a published tag and the Gitea release generated from it are
+historical records. Later corrections on `main` do not rewrite that published
+record. Material release errors require the failure handling defined by the
+release procedure rather than moving a published tag or overwriting its
+release.
+
+### Executable Authority
+
+CLI parsing and help generation are the executable authority for accepted
+commands and flags. Configuration structs, defaults, loading, and validation
+are the executable authority for configuration behavior. Schemas and embedded
+assets are the executable authority for validated formats and template
+execution. Tests protect selected contracts and invariants but do not become a
+second documentation reference merely by asserting them.
+
+Canonical documentation must be checked against these authorities whenever the
+corresponding behavior changes.
+
+### Security Topics
+
+This policy owns what documentation and examples may contain. Architecture owns
+application security boundaries and invariants. Configuration owns
+credential-supply mechanisms. Operations owns permissions and handling of
+sensitive runtime artifacts. Integration documents own consumer-visible
+security contracts. Internal documents own implementation mechanisms only.
+
+## Architecture Decision Records
+
+Use sequentially numbered ADR filenames such as
+`0001-record-architecture-decisions.md`. Follow the lightweight Nygard format:
+
+1. title;
+2. status;
+3. date;
+4. context;
+5. decision;
+6. alternatives considered;
+7. consequences.
+
+Use one of these statuses:
+
+- **Proposed:** the decision is under consideration and may change;
+- **Accepted:** the decision is approved, whether or not implementation is
+  complete;
+- **Rejected:** the proposed decision was considered and not adopted;
+- **Superseded:** a later accepted ADR replaces the accepted decision.
+
+A proposed ADR transitions to Accepted or Rejected. An Accepted ADR transitions
+to Superseded only when a later Accepted ADR replaces it. An ADR may be created
+as Accepted when the decision has already been made.
+
+Treat the decision content of an Accepted ADR as immutable. A changed decision
+requires a later ADR rather than a rewrite of the accepted record. A Superseded
+ADR must link to its replacement, and the replacement must link back. Rejected
+architectural alternatives belong in the ADR; rejected feature ideas belong in
+a roadmap when they need to be retained.
+
+## Document Lifecycle
+
+Create durable current-state documentation with the implementation it
+describes. Update its canonical owner in the same change when behavior changes.
+If ownership moves, remove the old definition and leave a link where navigation
+remains useful.
+
+Roadmaps are temporary coordination documents. When their work is complete,
+record completion, move any still-useful decisions or contracts to their
+durable owners, update incoming links, and archive or remove the roadmap
+according to repository practice. Do not preserve completed roadmaps as a

+
+Release notes are durable historical summaries rather than temporary roadmaps.
+Keep them concise, retain them after publication, and keep current contracts in
+their canonical owners.
+
+Before completing documentation work:
+
+- verify affected behavior and examples;
+- check commands, flags, fields, defaults, schemas, paths, and identifiers
+  against their implementation;
+- keep unimplemented behavior in a roadmap, subject to the ADR exception;
+- validate links and fenced examples;
+- confirm non-owning documents summarize and link rather than redefine;
+- remove stale or unsupported claims; and
+- confirm that no secrets or sensitive private data were added.

+# Testing Policy
+
+## Purpose
+
+Our tests exist to make **incorrect changes expensive and correct changes
+cheap**.
+
+We do not optimize for test count, line coverage, exhaustive isolation, or the
+fewest possible tests. We optimize for sufficient confidence in important
+behavior while imposing as little unnecessary friction as possible on future
+development.
+
+## Every Test Has A Cost
+
+Every test has an immediate cost and a continuing lifetime cost. It must be
+written, reviewed, executed, understood, diagnosed when it fails, updated when
+legitimate behavior changes, and maintained as fixtures and dependencies
+evolve.
+
+Tests also create cognitive and architectural friction. They can constrain
+refactoring, duplicate policy, slow feedback, add noise to failures, and cause
+harmless implementation changes to require unrelated suite edits.
+
+A test is warranted when the confidence it provides justifies those costs.
+Apply that judgment at two levels:
+
+1. **Per test:** What realistic defect does this test detect, how consequential
+   would it be, and is that protection worth the test's lifetime cost?
+2. **Across the suite:** Does this collection provide materially more
+   confidence than a smaller, simpler suite would?
+
+Prefer a lean suite that provides sufficient confidence in the risks that
+matter without redundant or low-value tests. Some friction is intentional:
+tests should make dangerous changes, such as corrupting state, breaking
+compatibility, violating security boundaries, or reintroducing subtle defects,
+require deliberate review. They should not make ordinary internal changes
+needlessly expensive.
+
+Maintenance cost is not a reason to omit testing by default. When omitting a
+plausible test, be able to explain why the protected failure is low-risk,
+already covered, obvious, reversible, or cheaper to detect elsewhere. Favor
+testing when failure would be consequential, subtle, or difficult to observe.
+
+## Default Testing Style
+
+Use a classical or Detroit-style approach:
+
+- Test observable behavior, resulting state, contracts, and invariants.
+- Use real internal collaborators when they are fast and deterministic.
+- Use fakes, stubs, or mocks primarily at expensive, nondeterministic,
+  destructive, or external boundaries.
+- Prefer package-level behavioral tests over tests coupled to private helpers
+  or internal call sequences.
+- Test exact collaborator interactions only when the interaction itself is a
+  requirement.
+
+Weatherreporter's important seams include clocks, Promptkit executors, HTTP
+services, Distributor uploads, filesystem roots, environment-backed secrets, and any
+future source of randomness or nondeterminism.
+
+## Execution Requirements
+
+The [development guide](../development.md) owns baseline repository validation.
+The default test suite is:
+
+```sh
+go test ./...
+```
+
+Run race-enabled tests when a change affects concurrent execution, goroutine
+lifecycle, shared mutable state, or cancellation coordination. Use a focused
+package command while iterating and `go test -race ./...` when the risk crosses
+package boundaries.
+
+Tests in the default suite must be deterministic, offline, and independent of
+real credentials. They must not invoke live Weather API, Promptkit providers, or
+Distributor services or depend on other mutable external infrastructure.
+Tests that require live infrastructure must be explicitly opt-in and clearly
+separated from the default suite.
+
+Control clocks, environment variables, filesystem roots, and machine-specific
+state when they affect behavior. Tests must be safe to repeat and must not
+depend on execution order or state left by an earlier test. Tests that modify
+process-global state may remain serial; use `t.Parallel()` only when the test
+and its collaborators are actually safe to run concurrently.
+
+## Test Types And Assets
+
+Use each test type where it protects a distinct risk:
+
+- Unit and package tests protect focused domain behavior and invariants through
+  the narrowest stable boundary.
+- Contract tests protect CLI behavior, configuration, durable artifacts,
+  schemas, templates, integration formats, compatibility, and stable error
+  identity.
+- Integration tests use real deterministic collaborators when correctness
+  depends on their interaction, while replacing live or nondeterministic
+  external boundaries.
+- App and CLI tests protect representative assembled generation, batch,
+  inspection, persistence, and notification workflows.
+- Fixtures must be minimal, synthetic, versioned with the behavior they
+  exercise, and free of credentials or private data.
+- Golden files are appropriate only when the complete output is intentionally
+  stable and semantic review of updates is practical.
+- Failure-path tests should cover consequential malformed input, dependency
+  failure, cancellation, partial results, and recovery behavior.
+
+## What Deserves Tests
+
+Prioritize tests for:
+
+1. CLI, configuration, artifact, template, integration, and package contracts.
+2. Meteorological domain rules and important invariants.
+3. Boundary conditions and malformed input.
+4. Failure handling, cancellation, retries, recovery, and partial success.
+5. Serialization, schemas, compatibility, and round trips.
+6. Previously observed or plausible regressions.
+7. Representative app and CLI workflows.
+
+A package-level contract is behavior relied upon by another package or major
+collaborator, not every observable implementation detail.
+
+For data integrity, destructive operations, compatibility, security,
+concurrency, idempotency, or recovery, presume that durable tests are required
+unless the behavior is already credibly protected at another layer.
+
+Do not add tests merely because a function, branch, or line exists. Do not add
+a test when the same meaningful risk is already adequately protected
+elsewhere.
+
+## Choose The Right Boundary
+
+Test through the narrowest stable boundary that expresses the behavior clearly.
+That may be:
+
+- a small pure function when dense domain logic is clearest there;
+- a package operation when several internal collaborators jointly produce the
+  behavior; or
+- a larger integration or app boundary when correctness emerges from
+  interaction.
+
+Do not force every behavior through oversized workflow tests. Do not test every
+private helper merely because it exists. Choose the boundary that provides
+durable confidence with the least incidental coupling.
+
+## Test Behavior, Not Implementation
+
+A test should protect a decision, contract, or invariant, not memorialize the
+current implementation. Before adding or retaining a test, ask:
+
+> What realistic defect would this test catch?
+
+A test is suspect when its main purpose is to detect that someone changed a
+private constant, renamed or split a helper, reordered equivalent operations,
+changed incidental formatting, replaced one correct algorithm with another, or
+refactored private structure without changing behavior.
+
+Refactoring should normally require no test edits unless the changed structure
+is itself contractual. A test can be factually correct and still have negative
+value when the behavior it protects is too incidental to justify its future
+cost.
+
+Use these expectations when evaluating failures:
+
+| Change | Expected effect on tests |
+| --- | --- |
+| Internal refactor that preserves behavior | Existing tests should normally remain unchanged and pass. |
+| Internal default change with no contractual significance | Tests should normally derive expectations from configuration or relationships rather than duplicate the old value. |
+| Intentional change to user-visible behavior, policy, schema, or compatibility | Relevant tests should be reviewed and changed deliberately. |
+| Accidental contract or invariant violation | Tests should fail; fix production code rather than rewriting tests to accept the defect. |
+
+A failing test is not necessarily a test that should be edited. Many tests may
+correctly fail because of one production defect. The maintenance smell is a
+correct internal change that requires unrelated expectation changes throughout
+the suite.
+
+## Separate Mechanism From Policy
+
+Do not duplicate configurable thresholds and defaults throughout the suite.
+Test mechanisms relationally: a configured valid value is accepted, a value
+outside the permitted relationship is rejected, and runtime behavior respects
+the configured value.
+
+Test an exact default when its literal value is itself a documented user,
+operational, safety, protocol, or compatibility contract. The same distinction
+applies to timeouts, capacities, retry counts, ranges, thresholds, and output
+limits.
+
+When concurrency limits are introduced, distinguish configuration enforcement
+from runtime enforcement. Validate accepted and rejected settings separately
+from measuring whether observed peak concurrency respects the configured
+limit.
+
+## Avoid Semantic Duplication
+
+Each behavior should have a clear test owner:
+
+- CLI parser tests own arguments, flags, and command construction.
+- Config tests own loading, precedence, defaults, secrets, and validation.
+- Domain tests own weather transformations and invariants.
+- Adapter tests own HTTP, Promptkit/provider, and upload boundaries.
+- Orchestrator tests own workflow ordering, persistence, partial success, and
+  failure propagation.
+- State tests own path derivation, atomic artifacts, lookup, and round trips.
+- Template and generated-text tests own schemas, render contexts, and rendered
+  output contracts.
+
+Higher-level tests should not repeat every lower-level case. Tests that are
+individually reasonable may still be collectively redundant; assess the
+marginal protection of each additional test.
+
+## Use Test Doubles Deliberately
+
+Choose the least elaborate double that provides the required control or
+observation:
+
+1. Prefer real collaborators when they are fast and deterministic.
+2. Use small in-memory fakes when realistic stateful behavior helps.
+3. Use stubs when a dependency only needs controlled responses.
+4. Use mocks when the interaction itself is contractual.
+
+Mocks are appropriate for requirements such as uploading exactly once, saving
+metadata before notification, propagating cancellation to Promptkit, or
+avoiding an external call after an earlier workflow failure. Do not use mocks
+merely to isolate every object or reproduce the implementation's call graph.
+
+## Go-Specific Guidance
+
+Use:
+
+- table-driven tests for meaningful behavioral categories and boundaries;
+- `t.TempDir()` for real filesystem behavior;
+- `httptest.Server` for realistic Weather API interactions;
+- test-controlled clocks for periods and RunIDs;
+- fake Promptkit executors or provider clients for Promptkit behavior;
+- fake upload clients for Distributor behavior;
+- fuzz tests when parsers, normalization, or path handling have a broad and
+  consequential input space;
+- golden files only when complete output stability is intentional; and
+- a small number of representative app and CLI workflow tests.
+
+Avoid exact error-string assertions unless wording is contractual. Prefer
+`errors.Is`, `errors.As`, typed errors, structured fields, or the smallest
+stable semantic fragment that identifies the failure. At CLI boundaries,
+prefer structured summaries, exit behavior, and stable classifications over
+snapshots of complete diagnostic wording.
+
+Golden-file updates must require an explicit local flag. Ordinary validation
+must never update golden files automatically, and maintainers must inspect the
+semantic diff before accepting an update.
+
+Keep tests readable and direct. Helpers and fixture frameworks must earn their
+maintenance cost; do not build elaborate infrastructure for small or isolated
+needs.
+
+## Coverage
+
+Coverage is a diagnostic, not a target. Use it to find untested critical
+branches and unexpectedly weak packages. Do not write low-value tests solely
+to increase a percentage or infer quality from coverage alone.
+
+Pure domain logic will often warrant higher coverage than CLI wiring or thin
+external adapters. Uneven coverage is acceptable when it reflects risk.
+
+## Regression Tests
+
+A bug fix should normally include a regression test that fails before the fix
+and passes afterward. Prefer the narrowest durable test of the violated
+contract or invariant.
+
+Retain the test when the defect could realistically recur and its consequences
+justify the ongoing cost. Remove or consolidate it if the design makes
+recurrence implausible or a stronger invariant test subsumes it.
+
+## Deleting Or Rewriting Tests
+
+Tests are maintained code, not permanent historical artifacts. Delete or
+rewrite a test when its maintenance cost exceeds the confidence it provides.
+Candidates include tests that:
+
+- require edits after harmless internal changes;
+- assert private constants without protecting a real contract;
+- duplicate the same policy across several layers;
+- verify mock choreography rather than outcomes;
+- snapshot large amounts of incidental output;
+- protect risks already covered more effectively elsewhere; or
+- are flaky, misleading, obsolete, or no longer correspond to a plausible
+  failure.
+
+Test removal must be deliberate and within the scope of the change. Identify
+the behavior the test protected and show that the behavior is covered more
+effectively elsewhere or that the failure is no longer plausible enough to
+justify durable coverage. Replace several brittle tests with one stronger
+behavior or invariant test when appropriate.
+
+Do not delete or weaken a test merely because it fails after a production
+change. First determine whether the failure exposes an accidental regression,
+an intentional contract change, or an implementation-coupled assertion.
+
+## Reviewing A Proposed Test
+
+When a proposed test's value or durability is not self-evident, ask:
+
+1. What realistic defect would it catch, and how consequential is that defect?
+2. Is the behavior already protected elsewhere?
+3. Which layer should own the test?
+4. Does it assert a durable contract or incidental implementation detail?
+5. What should cause it to fail, and what legitimate changes should not?
+6. Could a smaller or more direct test protect the same risk?
+7. What ongoing maintenance, execution, and diagnostic cost will it impose?
+
+Written answers are not required for every routine test. Do not add a test when
+its expected lifetime cost exceeds its expected protective value.
+
+## Definition Of Sufficient
+
+A suite is sufficient when:
+
+- important contracts and invariants are protected;
+- meaningful boundaries and failure modes are exercised;
+- consequential regressions are credibly protected against silent recurrence;
+- data integrity, destructive operations, compatibility, security,
+  concurrency, idempotency, and recovery receive risk-appropriate protection;
+- external boundaries have realistic local integration coverage;
+- representative complete workflows are tested;
+- failures provide useful signal rather than redundant noise; and
+- legitimate internal changes usually do not require test edits.
+
+Sufficiency is a risk judgment, not a coverage percentage or test count.
+Reassess it as Weatherreporter, its users, and the consequences of failure
+evolve.
+
+The governing rule is:
+
+> Test heavily where failure is consequential, subtle, or difficult to detect
+> after the fact. Test lightly where failure is obvious, reversible, and
+> inexpensive.

+# Release Procedure
+
+## Release Model
+
+Weatherreporter publishes executable binaries through tagged commits on
+`main`. Releases use stable semantic-version tags in the form
+`vMAJOR.MINOR.PATCH`. The current pipeline does not publish prereleases.
+
+Every release has one nonempty, version-matched note at
+`docs/releases/<tag>.md`. After the tag is pushed, the Woodpecker release
+pipeline validates the tagged source, builds six binaries, creates SHA-256
+checksums, and creates the corresponding Gitea release. The pipeline uses the
+checked-in release note as the Gitea release body and does not overwrite an
+existing release.
+
+Before `v1.0.0`, a minor release may deliberately change user-facing
+interfaces when its release note explains the compatibility impact and
+required operator action. Patch releases must not intentionally break the
+documented CLI, configuration, durable artifact, or integration contracts in
+their minor line.
+
+Published tags and their generated releases are immutable. Never move, reuse,
+or delete a published tag, and never manually overwrite the release produced
+from it.
+
+## Select The Version And Write The Release Note
+
+Choose an unpublished version and export it as `RELEASE_VERSION`. Run the
+commands in this procedure from the Weatherreporter repository root in one
+POSIX shell:
+
+```sh
+export RELEASE_VERSION=vMAJOR.MINOR.PATCH
+```
+
+Create `docs/releases/$RELEASE_VERSION.md` with this structure:
+
+```markdown
+# Weatherreporter vMAJOR.MINOR.PATCH
+
+This release ...
+
+## Summary
+
+Summarize the release's purpose and most important outcomes.
+
+## Compatibility
+
+State compatibility with the preceding release and identify any changed CLI,
+configuration, durable artifact, integration, or operating contract.
+
+## Upgrade
+
+State the operator actions required to upgrade, or state that no special
+action is required.
+
+## Changes
+
+Describe the material user-visible, operational, and maintainer-visible
+changes. Link to canonical documentation for exact current contracts.
+```
+
+The note is a concise changelog and adoption aid, not a replacement for current
+documentation. Update every affected canonical document in the same candidate
+commit. Do not include credentials, private infrastructure details, or claims
+that are not true of the candidate.
+
+Require the version, path, heading, and minimum sections before continuing:
+
+```sh
+set -eu
+
+: "${RELEASE_VERSION:?export an unpublished vMAJOR.MINOR.PATCH version}"
+if ! printf '%s\n' "$RELEASE_VERSION" |
+    grep -Eq '^v(0|[1-9][0-9]*)\.(0|[1-9][0-9]*)\.(0|[1-9][0-9]*)$'
+then
+    printf '%s\n' "invalid release version: $RELEASE_VERSION" >&2
+    exit 1
+fi
+
+RELEASE_NOTE="docs/releases/$RELEASE_VERSION.md"
+export RELEASE_NOTE
+
+test -s "$RELEASE_NOTE"
+grep -Fx "# Weatherreporter $RELEASE_VERSION" "$RELEASE_NOTE"
+grep -Fx '## Summary' "$RELEASE_NOTE"
+grep -Fx '## Compatibility' "$RELEASE_NOTE"
+grep -Fx '## Upgrade' "$RELEASE_NOTE"
+grep -Fx '## Changes' "$RELEASE_NOTE"
+```
+
+## Validate The Candidate
+
+Run the same substantive checks enforced by the tag pipeline before committing
+the release note:
+
+```sh
+test -z "$(git ls-files go.work go.work.sum)"
+test ! -e vendor
+if grep -Eq '^[[:space:]]*replace([[:space:]]|\()' go.mod
+then
+    printf '%s\n' 'go.mod contains a replacement' >&2
+    exit 1
+fi
+
+GOWORK=off go test -count=1 ./...
+GOWORK=off go test -race -count=1 ./...
+GOWORK=off go vet ./...
+GOWORK=off go build ./...
+GOWORK=off go mod tidy -diff
+
+unformatted=$(
+    git ls-files '*.go' |
+        while IFS= read -r go_file
+        do
+            gofmt -l "$go_file"
+        done
+)
+test -z "$unformatted"
+git diff --check
+git diff --cached --check
+```
+
+Follow every added or changed Markdown link and confirm that its local target
+exists. Review the candidate for generated binaries, test output, credentials,
+temporary files, workspace files, replacements, vendored dependencies, and
+other files that do not belong in source control.
+
+## Publish The Candidate Commit
+
+Commit the release note and any final current-state documentation updates, then
+push `main` through the ordinary repository workflow:
+
+```sh
+git add "$RELEASE_NOTE"
+git commit -m "Document Weatherreporter $RELEASE_VERSION"
+git push origin main
+```
+
+Do not tag an uncommitted or unpushed candidate. Record and export the exact
+candidate commit after the push:
+
+```sh
+RELEASE_COMMIT=$(git rev-parse --verify 'HEAD^{commit}')
+export RELEASE_COMMIT
+```
+
+## Guard And Tag The Candidate
+
+Run this guard immediately before creating the tag. It requires a clean
+checkout on synchronized `main`, valid module hygiene, the version-matched
+release note, and an unpublished local and remote tag:
+
+```sh
+check_release_candidate() {
+    test "$(git branch --show-current)" = main
+    test -z "$(git status --porcelain)"
+
+    gowork_value=$(go env GOWORK)
+    case "$gowork_value" in
+        ''|off) ;;
+        *)
+            printf '%s\n' "active Go workspace: $gowork_value" >&2
+            return 1
+            ;;
+    esac
+
+    test -z "$(git ls-files go.work go.work.sum)"
+    test ! -e vendor
+    if grep -Eq '^[[:space:]]*replace([[:space:]]|\()' go.mod
+    then
+        printf '%s\n' 'go.mod contains a replacement' >&2
+        return 1
+    fi
+
+    test -s "$RELEASE_NOTE"
+    grep -Fx "# Weatherreporter $RELEASE_VERSION" "$RELEASE_NOTE"
+
+    git fetch origin main --tags
+    test "$RELEASE_COMMIT" = \
+        "$(git rev-parse --verify 'refs/remotes/origin/main^{commit}')"
+
+    if git show-ref --verify --quiet "refs/tags/$RELEASE_VERSION"
+    then
+        printf '%s\n' "local tag already exists: $RELEASE_VERSION" >&2
+        return 1
+    fi
+    if test -n "$(
+        git ls-remote --tags origin \
+            "refs/tags/$RELEASE_VERSION" \
+            "refs/tags/$RELEASE_VERSION^{}"
+    )"
+    then
+        printf '%s\n' "remote tag already exists: $RELEASE_VERSION" >&2
+        return 1
+    fi
+}
+
+check_release_candidate
+```
+
+Create a lightweight tag, matching Weatherreporter's existing release tags,
+and bind it explicitly to the guarded commit:
+
+```sh
+git tag "$RELEASE_VERSION" "$RELEASE_COMMIT"
+test "$(git cat-file -t "refs/tags/$RELEASE_VERSION")" = commit
+test "$(git rev-parse --verify "refs/tags/$RELEASE_VERSION^{commit}")" = \
+    "$RELEASE_COMMIT"
+git show --no-patch --decorate "refs/tags/$RELEASE_VERSION"
+```
+
+If inspection finds an error, delete the unpublished local tag, correct the
+candidate, and repeat the procedure. Once the tag is pushed, it is immutable.
+
+## Publish And Verify The Release
+
+Push only the selected tag ref. Do not use `git push --tags`:
+
+```sh
+git push origin \
+    "refs/tags/$RELEASE_VERSION:refs/tags/$RELEASE_VERSION"
+```
+
+The tag event starts the release pipeline. Its validation step rejects a
+non-stable semantic tag, a missing release note, module or repository hygiene
+violations, and any failing test, race test, vet, build, module-tidiness,
+formatting, or whitespace check. Its build step also verifies that the host
+binary reports `weatherreporter $RELEASE_VERSION`.
+
+Wait for the pipeline to succeed, then confirm that the Gitea release:
+
+- targets `RELEASE_COMMIT` through `RELEASE_VERSION`;
+- is titled `Weatherreporter $RELEASE_VERSION`;
+- uses `RELEASE_NOTE` from the tagged commit as its body;
+- contains `SHA256SUMS`; and
+- contains Linux, macOS, and Windows binaries for both `amd64` and `arm64`,
+  named `weatherreporter-$RELEASE_VERSION-<os>-<arch>` with `.exe` on Windows.
+
+Compare the remote tag with the guarded commit:
+
+```sh
+remote_commit=$(
+    git ls-remote --tags origin "refs/tags/$RELEASE_VERSION" |
+        awk 'NR == 1 { print $1 }'
+)
+test "$remote_commit" = "$RELEASE_COMMIT"
+```
+
+Download `SHA256SUMS` and every release binary into a new temporary directory,
+run `sha256sum --check SHA256SUMS`, and execute the binary for the maintainer's
+host platform with `--version`. It must print exactly:
+
+```text
+weatherreporter vMAJOR.MINOR.PATCH
+```
+
+## Failed Publication And Corrections
+
+If the tag pipeline fails after publication, preserve the tag and diagnose the
+failure from the pipeline logs. Fix the cause on `main`, select a new patch
+version, prepare a new release note, and repeat the complete procedure. Do not
+move or recreate the failed published tag.
+
+Do not manually edit an automatically generated Gitea release or republish its
+assets. A wording-only correction may be committed to the historical document
+on `main`, with an explicit correction note, but it does not alter the file at
+the tag or the generated release. Publish a new patch release when the error is
+material to installation, compatibility, security, or operation.

+# Weatherreporter v0.9.0
+
+Weatherreporter `v0.9.0` replaces its external Scriptorium execution path with
+an in-process Promptkit integration and makes prompt preparation, execution,
+validation, and failure artifacts first-class parts of each report run.
+
+## Summary
+
+- Promptkit `v0.4.0` now executes all generated text for Daily, Today,
+  Tomorrow, and Hourly reports.
+- The four exact-version prompts and their JSON Schemas are embedded in the
+  Weatherreporter binary.
+- Prompt preparation and execution have separate durable, redacted provenance
+  records, while sensitive prompt debugging is explicit and stored outside the
+  managed workspace.
+- Weather API collection now performs a warmup request and retries transient
+  transport, read, and selected HTTP failures.
+- Release binaries now report their embedded version and are published with
+  checksums through a guarded Woodpecker pipeline.
+
+## Compatibility
+
+This pre-`v1` minor release contains intentional configuration, CLI, and
+artifact changes that require review when upgrading from `v0.8.0`.
+
+- The `scriptorium:` configuration section is no longer supported. A file that
+  contains it fails with a migration error instead of silently ignoring it.
+  Use `promptkit:` configuration instead.
+- The previously exposed but unfinished three-day, weekend, and storm report
+  surfaces have been removed. Supported report IDs and `generate` commands are
+  `daily`, `today`, `tomorrow`, and `hourly`. The retired `storm_id`
+  Distributor template variable is also no longer accepted.
+- Generate and batch result items now expose `preparationPath` and
+  `executionPath` instead of the Scriptorium-oriented `preflightPath` and
+  `generatedTextResultPath`. An opt-in prompt capture may also add
+  `llmDebugPath`.
+- New runs write `weatherreporter.metadata.v2`, which records Promptkit
+  preparation and execution paths. Inspection and prior-run lookup continue to
+  read existing `weatherreporter.metadata.v1` records.
+- The built-in `weather_api.precision` default changed from `1` to `0`.
+  Configurations that explicitly set a value retain that value.
+- Report prose may differ because the embedded prompt corpus, structured
+  output path, alert presentation, and SPC background context have changed.
+
+The documented Go version remains 1.26. Distributor integration remains at
+`v0.5.0`. Existing managed workspaces do not require conversion.
+
+## Upgrade
+
+Replace the old Scriptorium block in the Weatherreporter configuration. The
+smallest equivalent Promptkit block is:
+
+```yaml
+promptkit:
+  timeout: 2m
+```
+
+The embedded prompts default to the Promptkit `gemini-flash-latest` profile.
+Ensure that the selected profile's credential environment variable is present,
+or configure `promptkit.profile`, an external `profile_file` or `profile_dir`,
+or the optional `promptkit.local` backend. Direct per-request API keys are not
+supported by Weatherreporter.
+
+Before upgrading automation or downstream processing:
+
+1. remove any `three-day`, `weekend`, or `storm` command, report override, and
+   `storm_id` template usage;
+2. update consumers of action-summary JSON to use the new preparation and
+   execution path fields;
+3. decide whether to retain the new precision default or explicitly configure
+   the previous value; and
+4. preserve the existing workspace if historical V1 runs must remain
+   inspectable.
+
+Scriptorium, its executable configuration, and its external prompt corpus are
+no longer needed by Weatherreporter. See the
+[configuration reference](../config.md), [CLI reference](../cli.md), and
+[Promptkit integration](../integrations/promptkit.md) for the current
+contracts.
+
+## Changes
+
+### Prompt Execution And Artifacts
+
+- Added a project-owned Promptkit adapter with exact prompt and profile
+  inspection, prepare-once execution, error classification, and bounded
+  execution timeouts.
+- Embedded version `1.0.0` of the Daily, Today, Tomorrow, and Hourly prompts and
+  their private generated-text schemas.
+- Added durable preparation and execution receipts with prompt, profile,
+  backend, model, hashes, timings, validation status, classified failures, and
+  paths to every artifact reached during the run. Credentials, endpoints,
+  rendered messages, request parameters, and generated content are excluded
+  from these managed records.
+- Added `--llm-debug-dir` for explicitly requested content-rich diagnostics.
+  Debug output must use an absolute path outside the managed workspace and is
+  written with restrictive filesystem permissions.
+- Preflight now validates each exact prompt and selected profile before weather
+  collection. Batch execution validates every candidate first, collects once,
+  and retains independent report progress and failure artifacts.
+
+See the [operations guide](../operations.md) for artifact layout, inspection,
+debug handling, and recovery.
+
+### Weather Collection And Report Content
+
+- Added a `/conditions/current` warmup before source collection and automatic
+  retry for transient transport and response-read failures and HTTP `408`,
+  `429`, `500`, `502`, `503`, and `504` responses.
+- Changed the default upstream precision query value to `0`.
+- Added embedded background definitions for recognized SPC categorical,
+  tornado, wind, and hail outlook products.
+- Made the Alert Digest more concise: alert descriptions are omitted, and an
+  SPC-only digest is rendered only for Enhanced, Moderate, or High categorical
+  risk.
+- Removed duplicated alert detail from the prompt-facing metadata module; the
+  alert digest remains its single prompt-facing owner.
+
+See the [Weather API integration](../integrations/weatherapi.md) for the request,
+retry, and response contract.
+
+### CLI, Documentation, Testing, And Releases
+
+- Added `weatherreporter --version`; tagged binaries report `v0.9.0`, while
+  ordinary local builds report `development`.
+- Reworked CLI summaries and inspection coverage around the Promptkit artifact
+  lifecycle and retained partial-result behavior.
+- Reorganized contributor, policy, user, operator, integration, template, and
+  internal documentation around explicit canonical owners.
+- Added focused single-report, batch, CLI, Promptkit adapter, durable-state,
+  and artifact-path coverage while simplifying orchestration internals.
+- Added guarded tag validation and reproducible release builds for Linux,
+  macOS, and Windows on `amd64` and `arm64`, with SHA-256 checksums and
+  changelog-backed Gitea releases.

-# Code Quality And Deduplication Audit
-
-## 1. Executive summary
-
-Overall code quality is good. The implementation is small, direct, and aligned
-with the documented architecture: CLI parsing is isolated in `internal/cli`,
-configuration is centralized in `internal/config`, report definitions live in
-`internal/report`, external systems sit behind adapters, and most domain logic
-is covered by focused tests.
-
-The codebase appears ready for a limited cleanup pass before the next major
-release. I did not find a major architectural risk that requires a broad
-rewrite.
-
-Top three refactoring targets:
-
-1. Centralize atomic file and JSON artifact writes. Similar write patterns now
-   exist in state, briefing, prompt input, Weather API bundle saving,
-   Scriptorium render saving, and report-copy code.
-2. Move report artifact naming, grouping, and compatibility policy closer to
-   the report registry. Related decisions are split across `internal/report`,
-   `internal/state`, and `internal/app`.
-3. Reduce repeated CLI/app inspection and config-loading scaffolding. The
-   inspect commands repeat parse/load/call/write patterns, and app inspection
-   repeats store and metadata lookup flows.
-
-Recommended cleanup should be incremental and behavior-preserving. Avoid a
-generic workflow engine, plugin layer, CLI redesign, or broad storage rewrite.

-
-## 3. High-confidence deduplication opportunities
-
-### Centralize atomic file and JSON artifact writes
-
-- Affected files/packages: `internal/state/filesystem.go`,
-  `internal/briefing/package.go`, `internal/promptinput/package.go`,
-  `internal/adapters/weatherapi/client.go`,
-  `internal/adapters/scriptorium/runner.go`, `internal/app/app.go`.
-- Duplicated or near-duplicated behavior: multiple functions marshal JSON,
-  create parent directories, create temp files in the target directory, write,
-  close, rename, and defer temp-file cleanup. `copyFileAtomic` repeats the
-  same write path for Markdown report copies. `scriptorium.SaveRenderResult`
-  duplicates state preflight saving and does not appear to be used by the app.
-- Why it matters: atomic write behavior is part of the state and recovery
-  contract. A future bug fix around permissions, fsync behavior, temp-file
-  cleanup, Windows rename behavior, or error context would need to be applied
-  in several places.
-- Recommended refactor: add a small internal file helper, likely under
-  `internal/state` if kept state-specific or a narrow `internal/fileutil`
-  package if used by adapters too. Provide helpers such as `WriteFileAtomic`,
-  `WriteJSONAtomic`, and possibly `CopyFileAtomic`. Then remove unused
-  duplicate save helpers or route them through the shared helper.
-- Suggested tests: keep existing state, app, adapter, briefing, and prompt input
-  save tests. Add one focused helper test for parent-directory creation,
-  overwrite behavior, and temp-file cleanup on write errors if the helper is in
-  a new package.
-- Risk level: low. This is a behavior-preserving mechanical cleanup if error
-  messages are kept compatible where tests assert them.
-
-### Centralize report artifact grouping, naming, and compatibility policy
-
-- Affected files/packages: `internal/report`, `internal/state/filesystem.go`,
-  `internal/app/app.go`, state and app tests.
-- Duplicated or near-duplicated behavior: `internal/report` owns report IDs,
-  prompt IDs, default output names, batches, and comparison strategies.
-  `internal/state` separately maps report IDs to artifact groups such as
-  `daily`, `three-day`, `weekend`, and `storm`. `internal/app` separately
-  converts `DefaultOutputName` underscores to hyphens for batch output copies.
-  `internal/state` also hardcodes compatible prior report matching instead of
-  asking the report catalog.
-- Why it matters: adding or renaming a report requires updates in several
-  packages. A bug in grouping or compatibility could affect state lookup,
-  Recent Changes, managed paths, and batch output names.
-- Recommended refactor: extend `report.Definition` or add registry helpers for
-  artifact group, managed output group, batch copy filename, and compatible
-  prior report IDs. Keep filesystem path joining in `internal/state`, but move
-  report identity policy out of state/app. Preserve current path strings and
-  output filenames.
-- Suggested tests: strengthen `internal/report` tests to assert each definition
-  exposes group, copy filename, and compatibility policy. Keep existing
-  `internal/state` path tests and batch output tests as regression coverage.
-- Risk level: medium-low. The behavior is user-visible through artifact paths
-  and `--out-dir` names, so preserve exact strings.
-
-### Collapse repeated inspect command and app lookup flow
-
-- Affected files/packages: `internal/cli/root.go`, `internal/app/inspect.go`,
-  CLI and app inspect tests.
-- Duplicated or near-duplicated behavior: each inspect subcommand repeats flag
-  parsing, `config.Load`, app call, error handling, and JSON writing. The app
-  inspect functions repeatedly create the default store, load metadata by
-  RunID, and then load or derive a specific result.
-- Why it matters: adding another inspect view or changing config-loading/error
-  behavior would require edits in multiple cases. It also increases the chance
-  that one inspect command gains different output or error behavior.
-- Recommended refactor: add a small inspect command table in `internal/cli`
-  mapping command name to parser and handler. In `internal/app`, add an
-  internal helper that returns the store, metadata, and metadata path for a
-  RunID, then build briefing/data-package/prior/source views from that helper.
-- Suggested tests: keep the existing `TestRunInspectGeneratedArtifacts` and
-  missing metadata tests. Add a focused table test that each registered inspect
-  command accepts `--config` and rejects missing RunID where applicable.
-- Risk level: low. The refactor is local and should preserve public CLI output.
-
-### Remove or resolve unused report output config surface
-
-- Affected files/packages: `internal/config/config.go`,
-  `internal/config/load.go`, `internal/config/defaults.go`,
-  `internal/config/validate.go`, docs and examples if behavior changes.
-- Duplicated or near-duplicated behavior: `ReportOutputConfig` contains
-  `OutputDir` and `Paths`, and `LoadOptions.Output` writes to
-  `cfg.Reports.OutputDir`. Current command behavior uses `GenerateRequest`
-  `OutputPath` and `BatchRequest.OutputDir`; docs correctly say `--out` and
-  `--out-dir` control extra copies without changing config files. The report
-  output config fields do not appear to drive implemented behavior.
-- Why it matters: unused config fields are a maintenance hazard. They invite
-  future docs drift and make it unclear whether output policy belongs in config,
-  CLI requests, report definitions, or state.
-- Recommended refactor: decide one behavior before release. Either remove the
-  unused config surface and the `LoadOptions.Output` mutation, or implement
-  `reports.output_dir`/`reports.paths` as real defaults for generated extra
-  copies. Given current docs and CLI behavior, removal is the lower-risk option.
-- Suggested tests: config tests should assert only implemented config fields.
-  CLI tests should continue to cover `--out` and `--out-dir`.
-- Risk level: medium. This touches config structures and may affect users if
-  anyone has already copied old config fields, so pair the change with clear
-  release notes if removed.
-
-## 4. Medium-confidence opportunities
-
-### Reduce Weather API source fetch boilerplate
-
-- Affected files/packages: `internal/adapters/weatherapi/client.go`,
-  weather adapter tests.
-- Duplicated or near-duplicated behavior: optional source fetch methods repeat
-  request construction, missing handling, JSON decode, malformed-source policy,
-  source timestamp assignment, bundle assignment, and source recording. Hourly
-  is intentionally different because it is required and validates periods.
-- Why it matters: adding another Weather API source will likely copy this
-  structure and may accidentally diverge on missing-source policy or provenance.
-- Recommended refactor: introduce a small source specification/helper for
-  optional typed sources. Keep hourly special. Do not build a generic HTTP
-  ingestion framework.
-- Suggested tests: keep existing endpoint/query/missing-source tests. Add one
-  test that optional malformed data follows the configured missing-source
-  policy across at least two source specs.
-- Risk level: medium. The current explicit functions are readable; only refactor
-  if adding more source types or touching missing-source behavior.
-
-### Share Scriptorium render/run execution scaffolding
-
-- Affected files/packages: `internal/adapters/scriptorium/runner.go`,
-  Scriptorium adapter tests.
-- Duplicated or near-duplicated behavior: `Render` and `Run` both validate
-  common inputs, resolve binary/runner defaults, execute a command, copy
-  stdout/stderr/truncation/exit fields, and turn nonzero exit codes into
-  result-plus-error. Argument construction is already separated.
-- Why it matters: future changes to capture limits, redaction, timeout handling,
-  or nonzero exit formatting could drift between render and run.
-- Recommended refactor: introduce a private `execute` helper returning the
-  shared command result fields and preserving command-specific validation and
-  result structs.
-- Suggested tests: existing render/run argv and nonzero exit tests should remain
-  sufficient; add a timeout/non-exit error test if one is missing.
-- Risk level: low-medium. Keep the public adapter API and result JSON stable.
-
-### Consolidate storm time parsing and validation
-
-- Affected files/packages: `internal/cli/root.go`, `internal/report/period.go`,
-  CLI and report period tests.
-- Duplicated or near-duplicated behavior: CLI validates `--start`, `--end`,
-  parses both storm timestamps, and checks end after start. Report resolution
-  also validates storm start/end and has a `ParseStormPeriod` helper.
-- Why it matters: error wording and accepted timestamp behavior could drift
-  between CLI and report-level validation.
-- Recommended refactor: keep CLI-specific missing-flag errors in `internal/cli`,
-  but delegate parse/order validation to one helper after both values are
-  present.
-- Suggested tests: keep CLI tests for missing flags and RFC3339 parsing; keep
-  report period tests for invalid bounds.
-- Risk level: low.
-
-### Add a briefing-level weather signal helper, but keep prose local
-
-- Affected files/packages: `internal/briefing/daily.go`,
-  `internal/briefing/three_day.go`, `internal/briefing/weekend.go`,
-  `internal/briefing/storm.go`.
-- Duplicated or near-duplicated behavior: several builders aggregate ranges,
-  max precipitation, peak gusts, hazards, alert events, and risk labels from
-  daypart summaries. The report-specific prose and planning notes are
-  intentionally different.
-- Why it matters: threshold changes for "wind", "precipitation", or hazard
-  labels may need multiple edits.
-- Recommended refactor: add a narrow unexported helper in `internal/briefing`
-  for aggregating common signals from dayparts and alerts. Do not centralize
-  report-specific language, planning sections, or prompt-facing structure.
-- Suggested tests: briefing tests should assert unchanged daily, 3-day, weekend,
-  and storm package shape for representative fixtures.
-- Risk level: medium. This is useful only if kept small; over-consolidating
-  report prose would make the builders harder to read.
-
-### Clean up legacy daily-specific wrappers after generic report support
-
-- Affected files/packages: `internal/app/app.go`, `internal/state/store.go`,
-  `internal/state/filesystem.go`, app and state tests.
-- Duplicated or near-duplicated behavior: `DailyBriefingRequest`,
-  `DailyReportRequest`, `GenerateDailyBriefing`, `GenerateDailyReport`,
-  `BuildDailyBriefing`, `FindPriorDailySnapshot`, and `dailyRecentChanges`
-  mostly alias or forward to generic report functions.
-- Why it matters: wrappers create two names for the same behavior and encourage
-  future code to depend on the older daily-specific path.
-- Recommended refactor: remove unused wrappers or mark them as test-only
-  migration targets, then update tests to call the generic functions directly.
-  Keep any wrapper that is intentionally part of a public package contract, but
-  this repository uses `internal/`, so that concern is limited.
-- Suggested tests: app and state tests should continue to cover daily behavior
-  through generic generation and prior snapshot paths.
-- Risk level: low-medium. This is a small internal API cleanup, but it touches
-  many test call sites.
-
-### Reduce duplicated end-to-end test setup
-
-- Affected files/packages: `internal/cli/root_test.go`,
-  `internal/app/app_test.go`, adapter tests.
-- Duplicated or near-duplicated behavior: tests repeatedly create temp
-  workspaces, write YAML config strings, start representative Weather API
-  servers, create fake Scriptorium scripts, and glob managed artifact paths.
-- Why it matters: setup duplication makes behavior-preserving refactors noisier
-  and increases the chance that new tests accidentally use a subtly different
-  fixture.
-- Recommended refactor: add small package-local helpers for config writing,
-  test server setup, fake Scriptorium setup, and artifact glob/assertion.
-  Avoid a cross-package test framework unless duplication becomes painful in
-  more packages.
-- Suggested tests: this is test-only; existing tests should pass unchanged in
-  behavior.
-- Risk level: low.
-
-## 5. Boundary and responsibility concerns
-
-The main boundary concern is that `internal/state` imports the Scriptorium
-adapter package and exposes `SavePreflight(context.Context, report.Resolved,
-*scriptorium.RenderResult)` through `state.Store`. State needs to persist a
-preflight artifact, but it does not need to know that the artifact type comes
-from an external CLI adapter. This is a small leak across the documented adapter
-boundary.
-
-Recommended home: keep subprocess result construction in
-`internal/adapters/scriptorium`; have `internal/app` convert or pass the result
-to state through a state-owned preflight artifact type, a generic JSON artifact
-writer, or an app-owned persistence helper. This keeps adapter result types from
-becoming part of the state interface.
-
-The second boundary concern is report policy in state/app. `internal/state`
-should own filesystem layout mechanics, but report grouping and compatible
-prior report selection are report catalog decisions. `internal/app` should
-orchestrate batch copies, but batch copy filename policy should come from report
-definitions.
-
-The third concern is unused config surface. `internal/config` owns
-`ReportOutputConfig`, but current command behavior does not consume it. Either
-the app should use it explicitly or the config fields should be removed before
-they become accidental public API.
-
-## 6. Path, key, and naming construction review
-
-Local managed artifact paths are mostly centralized in
-`FilesystemStore.Paths`, which is good. That function owns the paths for
-briefing snapshots, metadata, data packages, preflight output, and managed
-Markdown reports.
-
-Cleanup targets:
-
-- `reportGroup` is private to `internal/state`, while report identity policy is
-  canonical in `internal/report`.
-- Batch extra-copy names are built in `internal/app` by replacing underscores in
-  `DefaultOutputName`. This derives a public filename by convention rather than
-  declaring it.
-- Metadata path resolution uses `metadataPathFromStored`, derived from
-  `BriefingPath`. This works today, but it means metadata path identity is
-  partially reconstructed from another artifact path instead of coming directly
-  from `ArtifactPaths`.
-- Tests in CLI/app/state hard-code path fragments in many places. These are
-  useful regression checks, but after report group/name helpers exist, tests
-  should assert through the helper or explicitly state they are path-contract
-  tests.
-
-No remote keys, cache paths, lock files, schema paths, or object-store paths are
-implemented.
-
-## 7. Resolution and catalog review
-
-Report resolution is mostly consistent. `internal/report` owns report
-definitions, prompt IDs, valid-period resolution, batches, and comparison
-strategy declarations.
-
-Places that should be brought closer to the catalog:
-
-- command-to-report mapping in `internal/app` (`ReportKind` to `report.ID`);
-- command-to-batch mapping in `internal/app`;
-- artifact group mapping in `internal/state`;
-- compatible prior report matching in `internal/state`;
-- batch copy filename behavior in `internal/app`;
-- "generated report" eligibility in `internal/app`.
-
-Recommendation: keep the public CLI command names in `internal/cli`/`app`, but
-let the report registry expose enough metadata that app and state do not need
-parallel switches over report IDs.
-
-Prompt and profile resolution is clean. Prompt IDs are declared in
-`internal/report`; Scriptorium profile/config/binary/extra args stay in config
-and the Scriptorium adapter. Data package naming is consistently
-`data_package=<path>`.
-
-Weather API source resolution is explicit but somewhat repetitive. A source
-catalog or source spec table could help if the number of upstream sources grows.
-
-## 8. Config and command-loading review
-
-Configuration loading is centralized in `internal/config`, and the documented
-precedence is reflected in code: CLI overrides, config file, built-in defaults.
-There is no duplicated YAML parsing or validation outside `internal/config`.
-
-Command loading is consistent but repetitive:
-
-- generate commands load config with `--config`, `--units`, `--tz`, and `--out`;
-- run commands load config with `--config`, `--units`, and `--tz`;
-- inspect commands load config with `--config` only.
-
-The inspect difference appears intentional because inspect commands do not
-fetch weather data or generate reports. The generate/run repetition is modest,
-but a small helper for building `config.LoadOptions` would reduce drift if more
-shared flags are added.
-
-The likely accidental issue is `LoadOptions.Output`: it mutates
-`cfg.Reports.OutputDir`, but current generation behavior separately uses
-`GenerateRequest.OutputPath`, and docs say output flags do not change config.
-This should be removed or given real semantics.
-
-## 9. State, manifest, or progress handling review
-
-The project has filesystem state but no manifest, checkpoint, resume, force, or
-dry-run system.
-
-State handling is generally consistent:
-
-- `FilesystemStore.Paths` centralizes managed artifact paths.
-- Store methods persist briefing, data package, preflight, metadata, and managed
-  report path preparation.
-- `GenerateReport` persists metadata before returning render errors when a
-  render result exists.
-- `RunBatchDetailed` continues independent reports and returns aggregate
-  results for CLI summarization.
-- Inspection loads metadata by RunID and then follows metadata paths.
-
-Cleanup targets:
-
-- State prior-snapshot lookup uses filesystem discovery plus hardcoded report
-  compatibility. This is currently acceptable, but compatibility policy should
-  be registry-driven before adding more report types.
-- `LoadMetadataByRunID` scans all reports through `ListReports`. This is simple
-  and fine at current scale, but it is the place to revisit if workspace size
-  grows.
-- `SaveMetadata` reconstructs the metadata path from `BriefingPath`, while most
-  other artifact paths come from `Paths`. Prefer carrying the metadata path
-  explicitly to reduce path coupling.
-
-No progress tracking drift exists because progress tracking is not implemented.
-
-## 10. Refactors to avoid
-
-Avoid these refactors for now:
-
-- A generic workflow engine for generation stages. The current explicit
-  orchestration is readable and well tested.
-- A plugin architecture for reports, sources, validators, or adapters. The
-  current registry and adapter packages are enough.
-- A broad CLI redesign or Cobra migration. The standard-library CLI is adequate
-  and documented.
-- A sweeping manifest or resume-system rewrite. There is no implemented resume
-  behavior to consolidate yet.
-- A generic source ingestion framework for the Weather API. A small helper or
-  spec table is enough if new sources are added.
-- Consolidating all report briefing prose. Similar thresholds can be factored,
-  but report-specific prompt inputs should remain readable and explicit.
-- Moving all test helpers into a global test package. Prefer package-local
-  helpers until duplication crosses package boundaries in a way that blocks
-  refactoring.
-- Removing path-contract tests merely because they duplicate strings. Some
-  hard-coded expected paths are valuable regression coverage.
-
-## 11. Recommended implementation sequence
-
-1. Path/key/naming helpers
-   - Add report registry metadata or helpers for artifact group, batch copy
-     filename, generated-report eligibility, and compatible prior report IDs.
-   - Preserve existing paths and filenames.
-   - Update state/app tests first or in the same commit.
-
-2. Atomic file and JSON helpers
-   - Introduce a narrow atomic file helper.
-   - Route state, briefing, prompt input, Weather API bundle saving,
-     Scriptorium preflight saving, and report-copy code through it.
-   - Remove unused save helpers if they no longer have callers.
-
-3. Config loading context
-   - Remove or implement `ReportOutputConfig` and `LoadOptions.Output`.
-   - Keep documented CLI output behavior stable.
-   - Add config regression tests around examples and CLI output flags.
-
-4. Command preflight/shared CLI parsing
-   - Add small helpers for common config-load options and inspect command
-     dispatch.
-   - Keep command errors and JSON output stable.
-
-5. Shared state lookup helpers
-   - Add app or state helpers for "load metadata by RunID, then load artifact".
-   - Keep inspect output unchanged.
-
-6. Adapter workflow cleanup
-   - Factor Scriptorium shared execution internals.
-   - Consider a Weather API optional-source helper only if source work is
-     already planned.
-
-7. Formatting/reporting cleanup
-   - Collapse `writeRunSummary` and `writeJSON` into one JSON writer helper.
-   - Leave stderr run logs as-is unless operator output requirements change.
-
-8. Test helper and fixture cleanup
-   - Add package-local helpers for repeated CLI/app setup.
-   - Keep fixtures small and deterministic.
-
-9. Dead-code/legacy sweep
-   - Remove daily-specific wrapper aliases and `FindPriorDailySnapshot` after
-     tests call generic paths.
-   - Re-run full tests and update internal docs if any package contracts change.
-
-## 12. Test strategy
-
-Tests to run before refactoring:
-
-- `go test ./internal/report ./internal/state`
-- `go test ./internal/app ./internal/cli`
-- `go test ./internal/config`
-- `go test ./internal/adapters/weatherapi ./internal/adapters/scriptorium`
-
-Tests to add before or during cleanup:
-
-- Report registry tests for artifact group, batch copy filename, generated
-  eligibility, and compatible prior report IDs.
-- Atomic file helper tests for parent directory creation, overwrite behavior,
-  and cleanup after write failure.
-- Config tests proving output flags do not mutate config, or tests defining the
-  implemented behavior if `reports.output_dir` is kept.
-- CLI inspect table tests that cover `--config` parsing and missing RunID
-  validation for each run-specific inspect command.
-- State tests that assert metadata path is taken from explicit artifact paths if
-  `metadataPathFromStored` is removed.
-- Scriptorium adapter tests for shared nonzero exit and timeout handling after
-  render/run execution is factored.
-
-Tests that can accompany refactors:
-
-- Weather API optional-source helper tests if source fetch boilerplate is
-  factored.
-- Briefing fixture tests if common signal aggregation is factored.
-- Test-helper cleanup can rely on existing package tests if no production code
-  changes.
-
-## 13. Appendix: findings not worth acting on
-
-- `internal/app.BuildBriefing` uses a switch over report IDs. This is acceptable
-  because app orchestration needs to dispatch to report-specific builders. A
-  registry of builder functions could be useful later, but it is not necessary
-  for the current report count.
-- CLI command parsing is explicit and somewhat repetitive. Do not replace it
-  with a framework. Small helpers are enough.
-- Daily, 3-day, weekend, and storm briefing builders have similar weather
-  thresholds. Some signal aggregation can be shared, but report-specific
-  sections and wording should stay local.
-- Weather API fetch methods are explicit. A helper is worthwhile only around
-  repeated optional-source mechanics; endpoint-specific decode and timestamp
-  behavior should remain clear.
-- Hard-coded expected artifact path fragments in tests duplicate path strings,
-  but several of those tests intentionally protect the on-disk contract.
-- `LoadMetadataByRunID` scans filesystem metadata. That is acceptable at the
-  current scale and should not be optimized without evidence of operational
-  pain.
-- Batch stderr logs are simple text. Do not introduce a logging subsystem unless
-  operator requirements become more complex.

-# Cleanup Roadmap
-
-## Purpose
-
-This roadmap defines the staged implementation plan for the code quality and
-deduplication cleanup identified in `docs/roadmap/audit.md`.
-
-The target audience is an LLM coding agent. Implement each stage in order.
-Each stage should leave the repository buildable, tested, and behaviorally
-equivalent unless the stage explicitly removes unused public-facing surface.
-
-## Cleanup Principles
-
-- Preserve public CLI syntax and output behavior unless a stage explicitly says
-  otherwise.
-- Preserve current managed artifact paths, report group names, RunID naming,
-  and batch output copy filenames.
-- Keep domain policy in `internal/report`, `internal/forecast`,
-  `internal/briefing`, and `internal/changes`, not in CLI or adapter packages.
-- Keep external system details behind adapter boundaries.
-- Prefer narrow, behavior-preserving helpers over broad framework-style
-  abstractions.
-- Add or update focused tests in the package that owns the behavior being
-  cleaned up.
-- Update non-roadmap documentation only after implemented behavior changes.
-- Do not revert unrelated worktree changes.
-
-## Decisions Locked
-
-- Add a narrow `internal/fileutil` package for reusable atomic file helpers.
-- Remove the unused `reports` config surface instead of implementing
-  config-driven output defaults.
-- Move report artifact group, batch copy filename, generated-report eligibility,
-  and compatible-prior policy into `internal/report`.
-- Keep public CLI command names and command-to-report mapping in `internal/app`
-  for now.
-- Do not include Weather API source-spec refactoring in the main cleanup
-  sequence.
-- Do not include broad briefing signal consolidation in the main cleanup
-  sequence.
-- Do not introduce Cobra, a workflow engine, plugin system,
-  manifest/resume/progress system, logging subsystem, or global test framework.
-- Treat the current unrelated deletion of `docs/roadmap/documentation.md` as
-  out of scope for cleanup implementation. Do not restore or further modify it
-  unless a later prompt explicitly asks for that.
-
-## Stage 1: Report Catalog And Path Policy
-
-Goal: make `internal/report` the canonical source for report identity policy.
-
-Implementation:
-
-- Extend `report.Definition` with:
-  - `ArtifactGroup string`
-  - `BatchOutputName string`
-  - `Generated bool`
-  - `CompatiblePriorIDs []report.ID`
-- Populate current exact values:
-  - Daily Today: artifact group `daily`, batch output `daily.md`, generated
-    true, compatible with Daily Today and Daily Tomorrow.
-  - Daily Tomorrow: artifact group `daily`, batch output `tomorrow.md`,
-    generated true, compatible with Daily Today and Daily Tomorrow.
-  - 3-Day: artifact group `three-day`, batch output `three-day.md`, generated
-    true, compatible with 3-Day.
-  - Weekend: artifact group `weekend`, batch output `weekend.md`, generated
-    true, compatible with Weekend.
-  - Storm: artifact group `storm`, batch output `storm.md`, generated true,
-    compatible with Storm.
-- Add small methods or helpers in `internal/report` for compatibility checks if
-  direct slice checks would duplicate logic in callers.
-- Update `internal/state` to use the resolved report definition's
-  `ArtifactGroup` instead of private `reportGroup`.
-- Update prior snapshot lookup to use `CompatiblePriorIDs` instead of a
-  state-owned compatibility switch.
-- Update `internal/app` to use `BatchOutputName` directly and remove
-  underscore-to-hyphen derivation.
-- Update generated-report eligibility checks to use `Definition.Generated`.
-- Preserve all existing managed artifact paths and batch copy filenames.
-
-Tests:
-
-- Add or update report registry tests that assert each definition's
-  `ArtifactGroup`, `BatchOutputName`, `Generated`, and `CompatiblePriorIDs`.
-- Keep state path tests as path-contract tests and preserve their expected path
-  strings.
-- Keep app batch output tests and preserve expected filenames such as
-  `tomorrow.md`.
-- Run:
-
-```bash
-go test ./internal/report ./internal/state ./internal/app
-```
-
-Acceptance criteria:
-
-- No report grouping switch remains in `internal/state`.
-- No batch output filename derivation by underscore replacement remains in
-  `internal/app`.
-- Existing artifact paths and output copy names are unchanged.
-
-## Stage 2: Atomic Artifact Writes And Adapter Boundary
-
-Goal: centralize durable write mechanics and remove adapter type leakage from
-state.
-
-Implementation:
-
-- Add `internal/fileutil` with:
-  - `WriteFileAtomic(path string, data []byte) error`
-  - `WriteJSONAtomic(path string, value any) error`
-  - `CopyFileAtomic(source string, target string) error`
-- Implement helpers with the current behavior:
-  - create parent directories with `0o755`;
-  - create temp files in the target directory;
-  - write, close, rename, and defer temp-file cleanup;
-  - preserve useful path context in errors.
-- Route these through `internal/fileutil`:
-  - state JSON writes;
-  - briefing package save;
-  - prompt input package save;
-  - Weather API bundle save;
-  - Scriptorium render result save if the helper remains;
-  - generated report extra-copy writes.
-- Remove duplicate private atomic write helpers once callers are migrated.
-- Remove `scriptorium.SaveRenderResult` if no caller still needs it after the
-  refactor.
-- Add `state.PreflightArtifact` with the same persisted JSON shape currently
-  produced from `scriptorium.RenderResult`.
-- Change `state.Store.SavePreflight` to accept `state.PreflightArtifact`, not
-  `*scriptorium.RenderResult`.
-- Convert `scriptorium.RenderResult` to `state.PreflightArtifact` in
-  `internal/app` immediately before saving preflight output.
-- Keep subprocess result construction and interpretation in
-  `internal/adapters/scriptorium`.
-
-Tests:
-
-- Add `internal/fileutil` tests for parent directory creation, overwrite
-  behavior, and cleanup/error behavior.
-- Keep state, app, adapter, briefing, and prompt input save tests.
-- Run:
-
-```bash
-go test ./internal/fileutil ./internal/state ./internal/app ./internal/briefing ./internal/promptinput ./internal/adapters/weatherapi ./internal/adapters/scriptorium
-```
-
-Acceptance criteria:
-
-- Durable JSON and Markdown copy writes share one implementation.
-- `internal/state` no longer imports `internal/adapters/scriptorium`.
-- Persisted preflight JSON remains shape-compatible with current artifacts.
-
-## Stage 3: Remove Unused Report Output Config
-
-Goal: remove config fields that do not affect implemented behavior.
-
-Implementation:
-
-- Remove these unused config surfaces:
-  - `Config.Reports`
-  - `ReportOutputConfig`
-  - `LoadOptions.Output`
-  - default report output config values;
-  - `reports.output_dir` validation;
-  - `reports.paths` map initialization.
-- Update CLI generation config loading so `--out` remains only
-  `GenerateRequest.OutputPath`.
-- Keep `--out` and `--out-dir` behavior unchanged.
-- Update config tests and examples so they mention only implemented config
-  fields.
-- Update documentation in the same stage if non-roadmap docs still mention the
-  removed `reports` config surface.
-
-Tests:
-
-- Update config tests to assert config loading no longer has output-related
-  config behavior.
-- Keep CLI tests for `--out` and `--out-dir`.
-- Run:
-
-```bash
-go test ./internal/config ./internal/cli ./internal/app
-go run ./cmd/weatherreporter --help
-```
-
-Acceptance criteria:
-
-- No `ReportOutputConfig` or `LoadOptions.Output` symbols remain.
-- Example config files load through existing config tests.
-- CLI output-copy behavior remains command request behavior, not config behavior.
-
-## Stage 4: Inspect Command And State Lookup Cleanup
-
-Goal: remove repeated inspect scaffolding while preserving inspect output.
-
-Implementation:
-
-- Add a small inspect command table in `internal/cli`.
-- Keep `inspect reports` separate because it accepts `--limit` and does not
-  require a RunID.
-- For run-specific inspect commands, centralize:
-  - command name;
-  - flag parsing;
-  - config loading;
-  - app handler invocation;
-  - JSON output writing.
-- In `internal/app`, add an unexported helper that loads the default store and
-  metadata for a RunID.
-- Use the app helper for metadata, briefing, data-package, prior, and sources
-  inspection.
-- Collapse `writeRunSummary` and `writeJSON` into one JSON writer helper.
-- Preserve current JSON indentation and output shapes.
-
-Tests:
-
-- Keep `TestRunInspectGeneratedArtifacts`.
-- Keep missing metadata tests.
-- Add a table test proving run-specific inspect commands reject missing RunID
-  and accept `--config`.
-- Run:
-
-```bash
-go test ./internal/cli ./internal/app ./internal/state
-```
-
-Acceptance criteria:
-
-- Inspect command output is unchanged.
-- Config loading remains consistent across inspect commands.
-- Repeated store and metadata lookup code in app inspection paths is removed.
-
-## Stage 5: Small Adapter And Parser Deduplication
-
-Goal: reduce low-risk repeated validation and execution logic.
-
-Implementation:
-
-- In `internal/adapters/scriptorium`, add a private execution helper shared by
-  `Render` and `Run`.
-- Keep command-specific request validation and result structs.
-- Preserve:
-  - argv order;
-  - result JSON fields;
-  - stdout/stderr capture;
-  - truncation fields;
-  - timeout behavior;
-  - nonzero exit behavior and error text.
-- In storm CLI parsing, keep CLI-specific missing `--start` and `--end` errors.
-- After both storm bounds are present, delegate timestamp parsing and
-  end-after-start validation to `report.ParseStormPeriod`.
-- Do not introduce a generic Weather API ingestion framework in this stage.
-
-Tests:
-
-- Keep or add tests for Scriptorium render/run nonzero exits.
-- Keep storm tests for local timestamps, RFC3339 timestamps, missing flags, and
-  invalid bounds.
-- Run:
-
-```bash
-go test ./internal/adapters/scriptorium ./internal/cli ./internal/report
-```
-
-Acceptance criteria:
-
-- Scriptorium render/run behavior remains byte-for-byte compatible where tests
-  assert argv or output shape.
-- Storm accepted timestamp formats and error behavior remain stable.
-
-## Stage 6: Legacy Wrapper And Test Helper Cleanup
-
-Goal: remove stale generic-vs-daily duplication and reduce noisy test setup.
-
-Implementation:
-
-- Replace tests and internal callers of:
-  - `GenerateDailyBriefing`
-  - `GenerateDailyReport`
-  - `BuildDailyBriefing`
-  - `DailyBriefingRequest`
-  - `DailyReportRequest`
-- Use generic functions and types instead:
-  - `GenerateBriefing`
-  - `GenerateReport`
-  - `BuildBriefing`
-  - `BriefingRequest`
-  - `ReportRequest`
-- Remove `FindPriorDailySnapshot` from `state.Store` and
-  `FilesystemStore` after tests use `FindPriorSnapshot`.
-- Remove `dailyRecentChanges` if no callers remain.
-- Add package-local test helpers in `internal/cli` and `internal/app` for:
-  - writing test config files;
-  - fake Scriptorium setup;
-  - representative Weather API test server setup;
-  - artifact glob and assertion helpers.
-- Do not create a cross-package test framework.
-
-Tests:
-
-- Run:
-
-```bash
-go test ./internal/app ./internal/state ./internal/cli
-go test ./internal/...
-```
-
-Acceptance criteria:
-
-- Daily-specific app/state wrapper symbols listed above are gone.
-- Daily behavior remains covered through generic report-generation paths.
-- Test helper extraction does not reduce workflow coverage.
-
-## Stage 7: Documentation And Final Validation
-
-Goal: align implemented documentation after cleanup.
-
-Implementation:
-
-- Update non-roadmap docs only for behavior or internal contracts actually
-  changed by stages 1 through 6.
-- Inspect and update, as needed:
-  - `docs/config.md`
-  - `docs/internal/state.md`
-  - `docs/internal/scriptorium-adapter.md`
-  - `docs/internal/report-registry.md`
-  - `docs/policy/development.md`
-  - relevant files under `docs/integrations/`
-- Keep future or deferred cleanup ideas only under `docs/roadmap/`.
-- Do not document deferred Weather API source-spec or briefing signal refactors
-  as implemented.
-
-Validation:
-
-```bash
-go test ./...
-go run ./cmd/weatherreporter --help
-git diff --check
-```
-
-Run stale-symbol searches:
-
-```bash
-rg -n "ReportOutputConfig|LoadOptions\\.Output|FindPriorDailySnapshot|GenerateDailyReport|DailyReportRequest|SaveRenderResult" .
-```
-
-Review any matches manually. Matches under roadmap files may be acceptable
-because they describe planned or completed cleanup work.
-
-Acceptance criteria:
-
-- Non-roadmap docs describe only implemented behavior.
-- Config examples still load through config tests.
-- CLI help remains accurate.
-- No removed production symbols remain outside tests or roadmap references.
-
-## Deferred Refactors
-
-Do not include these in the main cleanup sequence:
-
-- Weather API optional-source spec/helper refactor.
-- Broad briefing weather-signal consolidation.
-- Generic workflow engine.
-- Plugin architecture.
-- Cobra migration.
-- Manifest/resume/progress system.
-- Global test helper package.
-- Logging subsystem.
-
-These can be revisited only when new source types, report types, or operational
-requirements make the duplication materially more expensive.
-
-## Global Validation Checklist
-
-Run focused tests after each stage, then run full validation after Stage 7.
-
-Required final checks:
-
-```bash
-go test ./...
-go run ./cmd/weatherreporter --help
-git diff --check
-```
-
-Required manual checks:
-
-- Public CLI syntax remains stable.
-- Managed artifact paths remain stable.
-- Batch output copy filenames remain stable.
-- `scriptorium` argv construction remains stable.
-- Weather API request query behavior remains stable.
-- Removed config fields are also removed from current-behavior docs and
-  examples.
-- Roadmap files are the only docs that describe deferred cleanup work.
-- No unrelated worktree changes are reverted.

+## Future Report Types
 
-## Deferred: Alternate Runtime Integrations
+Status: Proposed and unimplemented.
 
-These ideas are not current behavior:
+Possible future report types:
 
-- native LLM client inside `weatherreporter`;
-- database-backed state;
-- public HTTP API;
-- multi-location selection;
-- daemon mode;
-- multi-user authorization;
-- plugin system.
+- a short-fuse planning report distinct from the implemented Hourly Report, if
+  a separate product is needed
+- event-specific reports with stable event IDs
+- storm review or yesterday-style reports using historical observations
+- archive-focused report variants if generated report history becomes a
+  first-class product
+
+New reports should preserve the boundaries documented in the [report registry
+internals](../internal/report-registry.md).
+
+## Future Modules
+
+Status: Proposed and unimplemented.
+
+Possible future modules:
+
+- `hourly_table` for compact valid-period hourly facts
+- `forecast_delta` if a separate stanza is useful beyond current Recent
+  Changes
+- `weekend_planning` if weekend-specific planning guidance needs a dedicated
+  deterministic stanza
+- `storm_window_summary` if manual or automatic storm reports need a dedicated
+  prompt-facing storm-window module
+- separate AFD section aliases, such as `afd_key_messages`,
+  `afd_short_term_text`, and `afd_long_term_text`, if separate stanzas prove
+  more useful than `area_forecast_discussion.options.sections`
+- SPC, radar, QPF, snow/rain total, or historical-observation modules once
+  upstream sources and report requirements exist
+
+QPF fields such as `measurable_qpf_total_in` and `max_hourly_qpf_in` should
+remain omitted until a real upstream quantitative precipitation source is
+represented in `CollectedFacts`.
+
+Future module work should preserve the boundaries documented in [fact
+contracts](../internal/facts.md), [module internals](../internal/module.md), and
+[briefing internals](../internal/briefing.md):
+
+- keep upstream collection in app orchestration
+- keep upstream collection out of modules
+- keep broad reusable calculations in `DerivedFacts`
+- keep prompt-facing field shape inside module builders
+- use typed options for configurable module behavior
+- keep module snapshots structured and deterministic for Recent Changes
+
+## Distributor Notification Enhancements
+
+Status: Proposed and unimplemented.
+
+Single-report and batch Distributor notification are implemented. Current
+behavior is documented in the [Distributor adapter guide](../internal/distributor-adapter.md),
+[Distributor integration guides](../integrations/distributor/), and
+[operations guide](../operations.md). The following enhancements remain
+unimplemented:
+
+- `failure_policy: warn`
+- uploading metadata, module snapshots, data packages, or preflight artifacts
+- durable upload retry queues
+- distributor-specific CLI flags
+- distributor workspace scanning
+- destination routing, Markdown-to-HTML transformation, public URLs, or nginx
+  layout inside weatherreporter
+
+Any distributor enhancement should preserve the adapter boundary:
+weatherreporter selects explicit generated files and submits source bundles,
+while distributor owns destination routing and publication behavior.
+
+## Alternate Runtime Integrations
+
+Status: Proposed and unimplemented.
+
+These ideas remain unimplemented:
+
+- native LLM client inside `weatherreporter`
+- database-backed state
+- public HTTP API
+- multi-location selection
+- daemon mode
+- multi-user authorization
+- plugin system
+- dynamic module loading
+- user-defined module code
+- YAML-defined module schemas
+- module-owned Weather API fetching
 
 Each item needs its own design note before implementation. Non-roadmap docs
 must not describe these as available behavior.
+
+## Deferred Refactors
+
+Status: Deferred.
+
+These refactors should remain deferred until new requirements or recurring
+maintenance costs make the added abstraction worthwhile:
+
+- broad briefing weather-signal consolidation
+- generic workflow engine
+- Cobra migration
+- manifest, resume, or progress system
+- global test helper package
+- logging subsystem
+
+Any future implementation should preserve the existing public CLI, artifact
+paths, report identities, module boundaries, and adapter boundaries unless a
+separate roadmap explicitly changes them.

+# Promptkit Migration Implementation Plan
+
+Status: Completed; Stages 1–19 passed their exit gates.
+
+## Purpose And Authority
+
+This document records the completed implementation of the
+[Promptkit migration roadmap](promptkit.md) and its post-implementation audit
+remediation. The feature roadmap records scope, user intent, policy choices,
+and the implemented end state. This plan records implementation sequence,
+tests, and completion gates.
+
+Stages 12–19 were completed in order. They fixed additional defects exposed by
+their required tests only when those defects were within the same stated
+contract; they did not add new product behavior or reinterpret roadmap
+decisions.
+
+This plan follows the repository's
+[architecture](../policy/architecture.md),
+[documentation](../policy/documentation.md), and
+[testing](../policy/testing.md) policies.
+
+## Continuing Invariants
+
+- Keep `gitea.maximumdirect.net/eric/promptkit` pinned at exactly `v0.4.0`.
+- Keep Promptkit types inside `internal/adapters/promptkit`, its tests, and the
+  external prompt-asset contract test.
+- Preserve one Promptkit engine per `generate` or `run` invocation and one
+  shared engine for every sequential report in a batch.
+- Preserve exact prompt version `1.0.0`, the exact persisted YAML data-package
+  bytes, prepared execution, and preparation persistence before provider work.
+- Do not add retries, repair attempts, concurrent batch generation, direct
+  Markdown generation, arbitrary backend registration, or live-provider
+  tests.
+- Keep ordinary artifacts, errors, logs, and summaries free of credentials,
+  rendered messages, schemas, input bodies, generated bodies, endpoints, and
+  full effective parameter maps.
+- Keep sensitive debug artifacts opt-in, outside normal state, owner-only,
+  atomic, and free of credentials.
+- Treat an artifact path as reached only after the corresponding write or copy
+  succeeds. Never persist or summarize a merely derivable future path.
+- Preserve every safe reached path in partial app and CLI results even when a
+  later persistence, validation, rendering, copy, or notification step fails.
+- Keep v1 metadata read compatibility and write only v2 metadata for new runs.
+- Keep the default test suite deterministic, offline, and credential-free.
+- Run `git diff --check` before completing every stage. Run the full repository
+  gate in Stage 19.
+
+## Completed Migration Summary
+
+Stages 1–11 are implemented and committed. They remain summarized here to
+preserve the history and dependencies of the follow-up work.
+
+| Stage | Completed outcome |
+| --- | --- |
+| 1 | Removed the unfinished three-day, weekend, and storm product surfaces and retained Daily, Today, Tomorrow, and Hourly with exact prompt version `1.0.0`. |
+| 2 | Promoted the four operational prompts and canonical schemas into the embedded `internal/promptassets` source used by Promptkit and generated-text validation. |
+| 3 | Added the project-owned `internal/promptexec` inspection, preparation, execution, validation, debug, and error contract. |
+| 4 | Added the Promptkit v0.4.0 adapter with prepared execution, explicit value mapping, safe error classification, and offline model-client tests. |
+| 5 | Added Promptkit-era preparation and execution artifacts, metadata v2, new paths, and v1 decoding support. |
+| 6 | Added explicitly rooted, permission-restricted, atomic LLM debug persistence. |
+| 7 | Added Promptkit configuration, executor composition, and pre-collection prompt/profile/credential inspection. |
+| 8 | Cut single-report generation over to prepared Promptkit execution and v2 persistence. |
+| 9 | Added `--llm-debug-dir` and Promptkit-era single-report summary fields. |
+| 10 | Cut morning and evening batches over to one shared Promptkit executor and removed Scriptorium code, configuration, and dependency metadata. |
+| 11 | Updated canonical Promptkit documentation, removed the temporary Scriptorium corpus, and ran the available repository checks. |
+
+The post-implementation audit confirmed the principal dependency and package
+boundaries, but found incorrect reached-path bookkeeping, incomplete execution
+artifact updates, insufficient artifact validation, extensive loss of
+behavioral tests during the final cutover, and roadmap lifecycle text that was
+not finalized. The completed remediation addressed those findings without
+changing the intended feature scope.
+
+| Stage | Completed outcome |
+| --- | --- |
+| 12 | Corrected reached-path bookkeeping across metadata, app results, batch items, and CLI summaries. |
+| 13 | Hardened Promptkit-era durable state validation and restored v1/v2 state coverage. |
+| 14 | Recorded every downstream path reached after completed prompt execution. |
+| 15 | Restored assembled single-report behavioral and failure coverage. |
+| 16 | Simplified prompt-generation orchestration while preserving behavior. |
+| 17 | Restored assembled batch, planning, artifact, and notification coverage. |
+| 18 | Restored supported CLI, summary, safety, and historical inspection coverage. |
+| 19 | Reconciled canonical documentation and passed the complete repository verification gate. |
+
+## Stage 12: Correct Reached-Artifact Bookkeeping
+
+Status: Completed.
+
+### Goal
+
+Make metadata, app results, batch items, and CLI summaries truthful at every
+failure boundary: a nonblank path means that artifact was successfully
+created.
+
+### Work
+
+1. Change `state.BuildPromptMetadataFromBriefingMetadata` so it initializes
+   identity, schema, metadata destination, and only artifacts already saved at
+   the call site. It must not prepopulate raw-output, normalized-text,
+   render-context, managed-report, preparation, execution, notification, or
+   output-copy paths.
+2. In `generatePromptReport`, assign each metadata and `ReportResult` path
+   immediately after that artifact write succeeds and before attempting the
+   next write. In particular:
+
+   - do not initialize `ReportResult.ReportPath` from `Store.Paths`;
+   - record a saved failed-preparation receipt in the result before saving
+     metadata;
+   - record a saved failed or completed execution receipt before saving
+     metadata;
+   - retain raw, normalized, context, report, copy, and notification paths
+     when a later step fails; and
+   - keep `MetadataPath` unchanged when a metadata rewrite fails, because the
+     prior successfully written metadata record remains the reached version.
+
+3. Remove batch-item prepopulation from derived `Store.Paths` values.
+   `BatchReportResult` receives paths only from the returned `ReportResult` or
+   from a write that the batch itself successfully completed.
+4. Preserve current CLI field names and omission behavior. Human and JSON
+   summaries must omit every unreached path.
+5. Do not change artifact locations, filenames, schemas, report output, or
+   notification policy in this stage.
+
+### Tests
+
+- Add focused app tests for one representative report using real temporary
+  state plus a narrow failure-injecting store wrapper.
+- Fail the next persistence step immediately after a successful preparation
+  receipt, execution receipt, raw output, normalized output, render context,
+  managed report, output copy, and notification artifact; assert that the
+  returned result contains every reached path and no future path.
+- Include one preparation failure, one operational execution failure, and one
+  completed validation rejection to cover the three execution outcome shapes.
+- Add batch and CLI summary assertions proving unreached paths are omitted.
+- Run:
+
+  ```sh
+  go test ./internal/state ./internal/app ./internal/cli
+  git diff --check
+  ```
+
+### Exit Gate
+
+Every nonblank path in newly written metadata, app results, batch items, and
+CLI summaries names an artifact that exists. Every safe artifact successfully
+written before a later failure remains discoverable from the returned partial
+result.
+
+## Stage 13: Harden Durable State Contracts And Restore State Coverage
+
+Status: Completed.
+
+### Goal
+
+Make the v1/v2 wire boundary and Promptkit-era artifact validation explicit,
+strict, and durably tested.
+
+### Work
+
+1. Strengthen `PromptPreparationArtifact.Validate`:
+
+   - require report ID, Weatherreporter RunID, prompt ID, exact prompt version,
+     data-package path, nonzero start/end times, nonnegative duration, and an
+     end not earlier than the start;
+   - for success, require preparation provenance, prohibit an error, and
+     require its prompt ID/version and data-package path to match the top-level
+     artifact;
+   - for failure, require a classified bounded error and prohibit fabricated
+     preparation provenance.
+
+2. Strengthen `PromptExecutionArtifact.Validate`:
+
+   - require report ID, Weatherreporter RunID, prompt ID, exact prompt version,
+     nonzero start/end times, nonnegative duration, and an end not earlier than
+     the start;
+   - for success and validation rejection, require provenance and completed
+     validation, prohibit an operational error, and require the provenance
+     prompt ID/version to match the artifact;
+   - do not compare the provenance RunID with the Weatherreporter RunID because
+     the provenance value is Promptkit's run identity;
+   - for operational failure, require a classified bounded error and prohibit
+     invented provenance or completed validation.
+
+3. Validate required provenance fields for completed executions, including
+   Promptkit RunID, prompt and rendered hashes, selected profile/backend/model,
+   and data-package path. Permit usage counters and generated hash to be zero
+   when the provider legitimately reports no value.
+4. Restore focused filesystem and metadata tests for:
+
+   - exact v2 paths and filenames;
+   - preparation/execution round trips and required fields;
+   - metadata v2 round trips without legacy aliases;
+   - v1 decoding, normalized internal aliases, and v1-preserving re-marshaling;
+   - unknown schema rejection;
+   - report listing, RunID lookup, source/module/data-package inspection, and
+     retained v1 behavior for historical report IDs;
+   - atomic writes and unsafe workspace/path rejection; and
+   - prior-snapshot behavior for the four supported report IDs.
+
+5. Adapt useful tests from the deleted filesystem suite rather than recreating
+   redundant low-value cases. Do not restore Scriptorium writes or retired
+   report behavior.
+
+### Tests
+
+Run:
+
+```sh
+go test ./internal/state ./internal/app
+git diff --check
+```
+
+### Exit Gate
+
+The state package rejects incomplete or contradictory Promptkit-era artifacts,
+reads historical v1 records, writes only valid v2 records, and has focused
+offline coverage for its durable compatibility and filesystem contracts.
+
+## Stage 14: Complete Execution-Artifact Path Tracking
+
+Status: Completed.
+
+### Goal
+
+Make `PromptExecutionArtifact.Paths` accurately record every downstream
+artifact reached after a completed Promptkit run.
+
+### Work
+
+1. Treat the execution artifact as an atomically updated durable record of the
+   completed Promptkit execution and subsequent artifact destinations. Its
+   status, provenance, validation, usage, and timing remain the provider-run
+   outcome; later application failures do not change a successful Promptkit
+   status into an execution failure.
+2. Save the initial execution artifact after raw output is persisted, with
+   `RawOutputPath` populated.
+3. After each later successful write, update and atomically resave the same
+   execution artifact with the corresponding reached path:
+
+   - normalized generated text;
+   - render context;
+   - managed Markdown report;
+   - an explicitly requested extra output copy, only after the copy succeeds;
+     and
+   - a Distributor notification artifact, including a persisted failure or
+     status artifact when notification produced one.
+
+4. Keep metadata and execution-artifact path values consistent after every
+   successful checkpoint. Save the execution artifact before metadata so a
+   metadata failure does not erase knowledge of a reached downstream artifact.
+   Failure to update the execution artifact is terminal and returns a partial
+   result containing the downstream artifact that was already written.
+5. Refactor finalization return values only as needed to tell the orchestration
+   layer which copy and notification paths were actually written. Distributor
+   must continue uploading only the managed Markdown report.
+6. A validation-rejected execution ends after raw output and therefore records
+   only the raw-output path. An operational execution failure has no completed
+   provenance and records only safe paths reached before that failure.
+
+### Tests
+
+- Add table-driven execution-artifact lifecycle tests for success and every
+  downstream failure point.
+- Load the persisted execution artifact after normalized-text, context,
+  template, copy, metadata, and notification failures and assert its status and
+  exact reached paths.
+- Assert that execution artifacts never contain generated bodies, rendered
+  prompts, schemas, endpoints, parameters, or credentials.
+- Run:
+
+  ```sh
+  go test ./internal/state ./internal/app
+  git diff --check
+  ```
+
+### Exit Gate
+
+For every completed Promptkit run, its execution artifact contains exactly the
+safe downstream paths reached by the workflow and remains semantically correct
+when a later application stage fails.
+
+## Stage 15: Restore Single-Report Behavioral Coverage
+
+Status: Completed.
+
+### Goal
+
+Restore the risk-based application coverage removed during final cutover and
+prove the complete single-report Promptkit workflow through project-owned
+boundaries.
+
+### Work
+
+1. Reintroduce a focused app test harness using real state, prompt-input,
+   generated-text validation, render contexts, and templates with deterministic
+   collector, executor, notifier, clock, and filesystem boundaries.
+2. Add representative successful workflows for Daily, Today, Tomorrow, and
+   Hourly. Verify report identity, exact prompt version, one collection, exact
+   persisted YAML bytes passed to the executor, expected template output,
+   optional copy behavior, and managed-report notification source.
+3. Cover the required failure matrix:
+
+   - inspection and missing credentials before collection;
+   - preparation failure and callback persistence failure before provider work;
+   - execution-time credential disappearance;
+   - capacity rejection without retry;
+   - cancellation and deadline;
+   - generation and operational-validation failure;
+   - completed Promptkit schema rejection with retained raw output;
+   - generated-text decode/domain rejection;
+   - render-context and template failure;
+   - output-copy failure; and
+   - notification failure.
+
+4. Verify preparation persistence precedes provider execution, debug-write
+   failure prevents provider execution, and execution-debug failure preserves
+   previously reached normal and debug artifacts.
+5. Verify Recent Changes, prior-snapshot selection, output naming, and
+   Distributor template values for all four retained reports.
+6. Adapt useful tests from the deleted app suite. Omit Scriptorium mechanics,
+   subprocess interaction assertions, and retired report products.
+7. Fix defects exposed by these tests only when the expected behavior is
+   already decided by the roadmap or canonical policy. Record any new product
+   question instead of silently choosing it.
+
+### Tests
+
+Run:
+
+```sh
+go test ./internal/app
+go test -race ./internal/app ./internal/adapters/promptkit
+git diff --check
+```
+
+### Exit Gate
+
+The single-report workflow has deterministic behavioral coverage for all four
+reports, all consequential failure stages, artifact ordering, partial results,
+debug isolation, output copying, and notification behavior.
+
+## Stage 16: Refactor Prompt Generation Orchestration
+
+Status: Completed.
+
+### Goal
+
+Reduce the complexity and duplicated persistence logic in
+`generatePromptReport` without changing observable behavior.
+
+### Work
+
+1. Use the Stage 12–15 tests as the refactoring safety boundary. Do not weaken
+   assertions to accommodate structural changes.
+2. Split the current orchestration into small app-owned operations with clear
+   inputs and outcomes for:
+
+   - deterministic input and initial state construction;
+   - preparation callback persistence;
+   - preparation-failure persistence;
+   - operational-execution-failure persistence;
+   - completed execution and raw-output persistence;
+   - normalized text and render-context persistence;
+   - managed report, optional copy, metadata, and notification finalization;
+     and
+   - reached-path updates shared by success and failure paths.
+
+3. Keep workflow order visible in one coordinator. Do not introduce a generic
+   workflow engine, hidden retry loop, provider-specific app type, or mutable
+   global state.
+4. Centralize the repeated rule that a successful artifact write updates the
+   result before any following write can fail.
+5. Preserve error identities, safe text, atomic writes, exact bytes, debug
+   ordering, partial results, and notification behavior.
+
+### Tests
+
+Run:
+
+```sh
+gofmt -w internal/app/*.go
+go test ./internal/app ./internal/state ./internal/cli
+go test -race ./internal/app
+git diff --check
+```
+
+### Exit Gate
+
+The top-level coordinator communicates the workflow order without containing
+the full persistence implementation, duplicate failure branches are reduced,
+and every Stage 12–15 behavioral test passes unchanged.
+
+## Stage 17: Restore Batch Behavioral Coverage
+
+Status: Completed.
+
+### Goal
+
+Re-establish confidence that morning and evening batches preserve their
+pre-migration behavior while sharing one Promptkit executor.
+
+### Work
+
+1. Add assembled batch tests proving:
+
+   - one executor factory call and one executor per CLI invocation;
+   - inspection of the full candidate set before collection;
+   - one weather collection;
+   - existing morning/evening planning and ordering;
+   - sequential execution through the shared executor;
+   - continuation after an independent report failure;
+   - no retry after capacity rejection;
+   - distinct identities and debug directories for multiple Daily dates; and
+   - exact reached paths on successful and failed batch items.
+
+2. Restore notification coverage for disabled notification, suppressed
+   per-report notification, all-success batch notification, skipped
+   notification after report failure, and persisted notification failure/status
+   artifacts.
+3. Restore output-directory, Today/Tomorrow naming, dynamic Daily planning,
+   prior-snapshot, and managed-Markdown upload-source coverage.
+4. Adapt useful tests from the deleted batch portions of the app and CLI suites.
+   Do not restore retired report cases or Scriptorium fakes.
+5. Fix only roadmap-defined batch regressions exposed by the restored tests.
+
+### Tests
+
+Run:
+
+```sh
+go test ./internal/app ./internal/cli
+go test -race ./internal/app
+git diff --check
+```
+
+### Exit Gate
+
+Morning and evening batches are covered as assembled sequential workflows and
+demonstrably preserve collection, planning, continuation, output, debug,
+artifact, and notification contracts with one Promptkit executor.
+
+## Stage 18: Restore CLI And Inspection Coverage
+
+Status: Completed.
+
+### Goal
+
+Restore the user-facing command, summary, and historical inspection contracts
+removed with the old root test suite.
+
+### Work
+
+1. Add parser and resolver tests for all four generate commands, both batch
+   commands, shared flags, report-specific date rules, malformed input,
+   `--llm-debug-dir`, `--quiet`, output paths, and rejection of retired report
+   names.
+2. Add assembled CLI tests for representative successful single and batch
+   invocations using injected offline boundaries. Verify exactly one executor
+   construction per action.
+3. Cover pre-run errors with no invented run summary, successful and failed
+   JSON summaries, quiet-mode behavior, safe human status output, partial paths,
+   and omission of absent notification/debug fields.
+4. Restore inspection tests for report listing and v1/v2 metadata, modules,
+   data packages, prior snapshots, and sources. Include failed v2 runs and v1
+   fixtures using historical report IDs.
+5. Assert that routine output never contains rendered prompts, schema bodies,
+   data packages, generated bodies, endpoints, full parameters, credentials, or
+   secret-like dependency errors.
+6. Keep tests at stable CLI/app boundaries; do not restore assertions about
+   private parser formatting or Scriptorium subprocess mechanics.
+
+### Tests
+
+Run:
+
+```sh
+go test ./internal/cli ./internal/app ./internal/state
+go run ./cmd/weatherreporter --help
+git diff --check
+```
+
+### Exit Gate
+
+The supported CLI surface, summaries, quiet mode, partial failures, executor
+composition, and v1/v2 inspection behavior have deterministic offline coverage.
+
+## Stage 19: Finalize Documentation And Repository Verification
+
+Status: Completed.
+
+### Goal
+
+Close the audit remediation, make roadmap lifecycle state truthful, and verify
+the repository against the complete target contract.
+
+### Work
+
+1. Update `docs/roadmap/promptkit.md` from future tense and “unimplemented”
+   statuses to a completed roadmap record. Describe its old seven-report and
+   Scriptorium material explicitly as the pre-migration baseline rather than
+   current behavior.
+2. Mark Stages 12–19 and this implementation plan complete only after their
+   exit gates pass. Retain the concise completed-stage history unless the
+   documentation policy calls for archival in the same change.
+3. Review canonical architecture, app, state, CLI, Promptkit integration,
+   operations, troubleshooting, configuration, and testing documentation
+   against the corrected implementation. Update only actual current-state
+   discrepancies; do not duplicate the roadmap.
+4. Search current-state code, tests, examples, help, and non-roadmap
+   documentation for stale Scriptorium terms, retired reports, old artifact
+   fields, speculative-path descriptions, or claims of missing Promptkit
+   implementation.
+5. Confirm examples contain no credentials or private infrastructure values
+   and load through config tests.
+
+### Final Verification
+
+Run:
+
+```sh
+gofmt -w <all changed Go files>
+go mod tidy
+go vet ./...
+go test -count=1 ./...
+go test -race ./...
+go run ./cmd/weatherreporter --help
+git diff --check
+```
+
+Then verify explicitly:
+
+- `go list -m gitea.maximumdirect.net/eric/promptkit` reports `v0.4.0`;
+- no committed `go.work`, `replace`, secret fixture, or live-provider test
+  exists;
+- all four prompts inspect at exact version `1.0.0`;
+- no runtime prompt requests repair attempts;
+- v1 fixtures remain inspectable and new runs write only v2;
+- normal artifacts and output contain no sensitive prompt/debug content;
+- failed-run metadata, execution artifacts, app results, batch items, and CLI
+  summaries contain exactly the paths actually reached;
+- help exposes only Daily, Today, Tomorrow, Hourly, morning, and evening; and
+- managed Markdown remains the only Distributor upload source.
+
+### Exit Gate
+
+Every migration and audit-remediation criterion is demonstrably satisfied,
+the restored tests protect the consequential contracts, canonical
+documentation describes the corrected implementation, and both roadmap
+documents are marked complete.
+
+## Open Questions
+
+None. The roadmap and this completed plan record the decisions used for the
+audit remediation.

+# Promptkit Migration Roadmap
+
+Status: Completed roadmap record.
+
+## Purpose
+
+This roadmap records the scope, decisions, and completed outcome of replacing
+the external Scriptorium CLI integration with Promptkit. Canonical
+documentation outside `docs/roadmap/` owns the implemented behavior.
+
+## Pre-Migration Baseline
+
+Status: Historical migration input.
+
+Before the migration, Weatherreporter exposed seven report definitions, but
+only four had complete prompt-backed report implementations:
+
+- Daily Report: `weather.daily_generated_text`
+- Today Report: `weather.today_generated_text`
+- Tomorrow Report: `weather.tomorrow_generated_text`
+- Hourly Report: `weather.hourly_generated_text`
+
+The three-day, weekend, and storm commands and registry definitions had no
+corresponding Scriptorium prompt or schema and never formed complete
+operational report products. The `weather.daily_report` Scriptorium prompt was
+legacy source material and was not selected by the registry.
+
+The Scriptorium source corpus was retained temporarily under
+`docs/roadmap/scriptorium/` as migration input. It contained the four
+operational generated-text prompt definitions, their referenced content,
+private response schemas, shared instructions, and the unused legacy Daily
+Markdown prompt. The temporary corpus was removed after the runtime assets
+were reconciled and embedded.
+
+## Implemented End State
+
+Status: Completed.
+
+Weatherreporter pins
+`gitea.maximumdirect.net/eric/promptkit` at `v0.4.0` and uses it as the
+in-process engine for prompt inspection, prepared execution, provider calls,
+and first-pass output validation.
+
+The `scriptorium` executable, subprocess adapter, configuration, runtime
+dependency, direct-Markdown execution path, and integration documentation have
+been removed. The four operational reports continue to use structured
+generated text followed by weatherreporter-owned validation and Markdown
+templates.
+
+The unfinished three-day, weekend, and storm reports are not implemented as
+part of this migration. Their incomplete CLI, registry, documentation, and
+generation declarations are removed from the implemented surface before the
+migration is considered complete. Any future implementation of those products
+requires separate roadmap scope, prompt and schema design, tests, and
+documentation.
+
+Weather selection, forecast derivation, valid periods, module construction,
+Recent Changes, generated-text interpretation, Markdown templates, durable
+state, inspection, output copies, and Distributor notification remain owned by
+weatherreporter.
+
+The four report prompts and private response schemas are versioned embedded
+application assets. Operators configure Promptkit profiles without replacing
+the report-owned corpus. One Promptkit engine is constructed per CLI
+invocation and shared by every report in that invocation, including all
+reports in a morning or evening batch.
+
+Promptkit is isolated behind a weatherreporter-owned execution contract.
+Promptkit request, result, validation, error, profile, backend, and provider
+types do not leak into application orchestration, report definitions, domain
+packages, CLI summaries, durable state contracts, or Distributor behavior.
+
+## Goals
+
+Status: Completed migration outcomes.
+
+- Removed the Scriptorium runtime dependency and subprocess boundary.
+- Migrated the four operational report prompts to Promptkit `v0.4.0`.
+- Used prepared execution to persist preparation provenance before provider work
+  while executing the exact frozen snapshot.
+- Validated report prompt and profile selections before weather collection when
+  the required information is available.
+- Preserved deterministic module snapshots and structured Recent Changes.
+- Preserved generated-text domain validation and repository-owned Markdown
+  rendering.
+- Preserved context cancellation, actionable errors, secret redaction, and
+  inspectable failures.
+- Improved durable prompt provenance with prompt, input, profile, model,
+  validation, usage, and timing metadata.
+- Kept content-rich prompt and response diagnostics separate from routine
+  metadata and CLI output.
+- Kept tests offline and deterministic through injected Promptkit model
+  clients and fixtures.
+- Removed incomplete report declarations from the implemented product surface
+  rather than creating new report products during an integration migration.
+
+## Non-Goals
+
+Status: Completed migration constraints.
+
+The completed migration did not:
+
+- create prompts, schemas, templates, or completed products for three-day,
+  weekend, or storm reports;
+- preserve the unused `weather.daily_report` legacy Markdown prompt as an
+  active runtime asset;
+- preserve a direct-Markdown LLM generation mode;
+- move meteorological selection, derivation, thresholds, or comparison logic
+  into prompts or Promptkit;
+- send raw unbounded Weather API responses to the model;
+- replace weatherreporter's generated-text domain validation or Markdown
+  template rendering;
+- add a general workflow engine, provider plugin system, or arbitrary backend
+  registry;
+- add automatic provider, validation, repair, or capacity retries;
+- add concurrent report generation to the sequential batch workflow;
+- expose Promptkit types as weatherreporter contracts;
+- keep a production-selectable Scriptorium/Promptkit dual-run mode;
+- require Promptkit eager source validation, structured generation errors, or
+  semantic execution-target fingerprints; or
+- use an unpublished Promptkit commit, committed Go workspace, or committed
+  local module replacement.
+
+## Locked Decisions
+
+Status: Implemented migration decisions.
+
+### Dependency And Upgrade Boundary
+
+- The migration pins the tagged Promptkit `v0.4.0` release.
+- Coordinated local development may temporarily use the sibling Promptkit
+  checkout, but committed module metadata must reference the tagged release.
+- The adapter relies on the public root Promptkit package only.
+- A future Promptkit upgrade requires explicit review of prepared-execution
+  lifecycle, prompt and profile inspection, prompt/profile/schema formats,
+  error identities, validation behavior, capacity behavior, and the outbound
+  provider contract.
+- Promptkit's deferred eager source validation, structured generation errors,
+  and semantic execution-target fingerprints do not block this migration.
+
+### Operational Report Scope
+
+- The migration preserves these prompt IDs:
+  `weather.daily_generated_text`, `weather.today_generated_text`,
+  `weather.tomorrow_generated_text`, and `weather.hourly_generated_text`.
+- Each operational report definition selects the exact embedded prompt version
+  `1.0.0`; execution does not rely on ambiguous single-version lookup.
+- Morning and evening batch membership remains based on Today, Tomorrow, and
+  eligible future Daily reports.
+- Three-day, weekend, and storm are removed from current CLI help, parsing,
+  report registry membership, tests that claim implemented generation, and
+  non-roadmap documentation.
+- The future product concepts may remain under `docs/roadmap/`, but migration
+  verification does not invent outputs or compare nonexistent prompts.
+
+### Application Boundary
+
+- Promptkit remains an adapter boundary even though it runs in process.
+- A weatherreporter-owned contract represents prompt identity, preparation,
+  execution, output, validation, usage, provenance, and neutral error
+  categories.
+- The Promptkit adapter maps public Promptkit values into that contract.
+- App orchestration and test fakes depend on the project-owned contract, not
+  Promptkit.
+- Scriptorium-specific request, result, error, and generation-mode types are
+  removed rather than renamed and retained.
+
+### Prompt And Schema Ownership
+
+- Weatherreporter embeds the four operational prompt definitions, referenced
+  prompt content, shared prompt content, and private response schemas.
+- Assets remain separate files rather than inline Go strings.
+- The temporary corpus under `docs/roadmap/scriptorium/` is migration source
+  material, not the final runtime location.
+- Weatherreporter's existing generated-text domain types, schemas, and
+  templates remain the canonical application contract. Imported Scriptorium
+  assets are reconciled with that contract rather than copied blindly or kept
+  as duplicate runtime schemas.
+- The imported Daily schema's incorrect Today `$id` and title are corrected.
+- `confidence` is handled consistently across each prompt, provider-facing
+  schema, generated-text domain type, and template. The existing optional
+  weatherreporter field remains supported unless a separate domain decision
+  removes it.
+- Prompt input metadata identifies the serialized data package as YAML rather
+  than JSON.
+- Imported `pipeline-weather/...` schema paths are replaced with paths valid
+  inside the embedded Promptkit schema source.
+- Imported `repair_attempts: 2` values are removed or set to zero. The
+  migration does not rely on Promptkit's internal-only repair capability.
+- The unused `weather.daily_report` prompt is not promoted into runtime assets.
+- One centralized embedded prompt/schema source is sufficient; Weatherreporter
+  does not need Notarius's multi-module asset-flattening registry.
+
+### Profiles, Backends, And Credentials
+
+- Execution profiles remain operator-configurable rather than embedded report
+  policy.
+- Each embedded operational prompt declares Promptkit's built-in
+  `gemini-flash-latest` profile as its default.
+- `gemini-flash-latest` is intentionally a moving model alias. The execution
+  record captures the effective model identity, but operators who require a
+  pinned model must select an explicit external profile.
+- Configuration supports at most one external profile source:
+  `promptkit.profile_file` or `promptkit.profile_dir`. The two fields are
+  mutually exclusive.
+- A nonblank `promptkit.profile` is the explicit request profile for every
+  report in the invocation and takes precedence over each prompt's
+  `default_profile`. A blank value uses the prompt default.
+- Promptkit's normal profile-source precedence remains intact: an external
+  matching profile takes precedence over an embedded built-in profile, and an
+  invalid matching external profile is an error rather than a reason to fall
+  back.
+- Weatherreporter exposes Promptkit's conventional `local` backend through the
+  narrow `promptkit.local.endpoint` and
+  `promptkit.local.concurrency_limit` configuration fields. It does not expose
+  arbitrary backend registration.
+- A configured local endpoint registers the engine-scoped `local` backend. An
+  operator-supplied external profile selects it with `backend: local` and owns
+  the model-specific settings; Weatherreporter does not invent a local model
+  profile.
+- Local concurrency defaults to one. A value of zero means unlimited, matching
+  Promptkit, and a negative value is invalid. Queue capacity and general
+  backend parameters are not exposed.
+- Credential values remain in environment variables or file-backed
+  environment secrets. Configuration contains only credential source names.
+- Provider credentials never appear in logs, errors, CLI output, durable
+  metadata, preparation records, execution records, or debug summaries.
+- Promptkit `InspectProfile` reports structural target and credential
+  requirements; Weatherreporter owns policy for checking configured
+  environment availability.
+- Promptkit revalidates environment credentials at `RunPrepared`; a successful
+  preparation does not promise that execution-time credentials remain
+  available.
+
+### Configuration Contract
+
+The replacement configuration surface is:
+
+```yaml
+promptkit:
+  profile: ""
+  profile_file: ""
+  profile_dir: ""
+  timeout: 2m
+
+  local:
+    endpoint: ""
+    concurrency_limit: 1
+```
+
+- `timeout` remains the transport-wide provider-call safety cap.
+- A blank local endpoint leaves the conventional local backend unregistered.
+- Scriptorium's `binary`, `config_path`, and `extra_args` settings have no
+  Promptkit equivalents and are removed.
+- Configuration validation rejects simultaneous `profile_file` and
+  `profile_dir` values, invalid local endpoints, negative concurrency, and
+  selected profiles that cannot resolve their backend.
+
+### Engine Construction And Inspection
+
+- One Promptkit engine is constructed per CLI invocation at the application
+  composition boundary.
+- Single-report generation and every report in a batch use that same engine.
+- Per-report orchestration does not construct a default engine.
+- Promptkit backend capacity state and HTTP transport are shared consistently
+  for the invocation.
+- Before collection, `InspectPrompt` checks every selected report's exact ID
+  and version, declared `data_package` input, default-profile metadata, prompt
+  hash availability, and declared output contract.
+- `InspectPrompt` is a point-in-time structural check. It does not load a JSON
+  Schema, resolve a profile, or freeze later execution.
+- Explicit profile overrides and relevant prompt defaults are checked with
+  `InspectProfile` before collection when application policy requires them.
+- `InspectProfile` is also point-in-time and does not check credential values.
+- Successful `PrepareExecution`, not inspection, is the per-run authority for
+  loaded schema, rendered content, frozen inputs, effective settings, and
+  durable execution provenance.
+
+### Prompt Input
+
+- Promptkit receives only the curated `data_package` produced by
+  `internal/promptinput`.
+- Weatherreporter serializes the package once, atomically persists those exact
+  bytes, and supplies the same bytes with a Promptkit inline artifact.
+- The managed data-package path may be supplied as non-secret provenance
+  through the inline artifact URI.
+- Weatherreporter does not delegate unrestricted path loading to Promptkit's
+  default file artifact reader.
+- Prompt inspection and adapter tests verify that `data_package` is required
+  and declared with the chosen YAML media type.
+
+### Prepared Execution
+
+- `Engine.PrepareExecution` replaces Scriptorium render preflight.
+- Weatherreporter obtains `PreparedExecution.Details`, maps a safe subset into
+  its own preparation record, and persists that record before calling
+  `Engine.RunPrepared`.
+- `RunPrepared` executes the frozen prompt, profile, schema, inputs, rendered
+  messages, target, and validation resources retained by the handle.
+- Every acquired handle is followed immediately by `defer handle.Discard()`.
+  Discard is safe after execution and releases unused private execution state.
+- Handles remain adapter-local, engine-bound, one-shot, in-process values.
+  They are never serialized, persisted, copied into app contracts, or treated
+  as restartable jobs.
+- Preparation and execution use independent contexts. Execution receives the
+  active report workflow context.
+- Capacity is not reserved during preparation. Capacity rejection can
+  therefore occur after a preparation record has been persisted.
+- `RunPrepared` consumes the handle on success and every operational failure.
+- Preparation details remain available from the adapter after execution or
+  discard, but rendered messages are not copied into routine durable state.
+- Promptkit execution timing excludes preparation and consumer-held delay.
+  Weatherreporter records preparation timing and execution timing separately.
+
+### Execution And Validation
+
+- All four operational reports use Promptkit JSON Schema output validation.
+- A completed Promptkit validation rejection returns a `RunResult`; the
+  adapter retains raw output and bounded validation details before failing the
+  report.
+- An operational generation or validation error returns no partial
+  `RunResult`.
+- Weatherreporter's `internal/generatedtext` validation remains the final
+  report-specific decode and domain boundary.
+- Weatherreporter's `internal/reporttemplate` remains responsible for managed
+  Markdown rendering.
+- Weatherreporter atomically persists Promptkit raw output and later artifacts
+  rather than asking Promptkit to choose managed filesystem paths.
+- No Promptkit output-repair behavior is assumed or requested.
+
+## Durable Artifacts And Observability
+
+Status: Implemented design constraints.
+
+Routine durable state retains useful non-secret provenance without persisting
+full rendered prompts.
+
+The preparation record contains:
+
+- prompt ID and exact version;
+- prompt definition hash;
+- rendered prompt hash;
+- input hashes;
+- selected profile and backend identity;
+- effective model identity;
+- output contract summary;
+- preparation start, end, and duration; and
+- the path of the exact persisted data package.
+
+The execution record and run metadata contain, when available:
+
+- Promptkit run ID;
+- prompt ID, version, and hashes;
+- input hashes;
+- selected profile, backend, and model identity;
+- generated-content hash;
+- token usage;
+- execution start, end, and duration;
+- validation status and bounded diagnostics; and
+- paths of separately persisted raw output, normalized generated text, render
+  context, managed Markdown, and other artifacts reached by the workflow.
+
+Provider endpoints, full effective model parameter maps, rendered messages,
+schema bodies, data-package contents, and generated content do not belong in
+routine metadata or CLI summaries.
+
+Rendered messages and other content-rich preparation or response diagnostics
+are available only when the operator supplies
+`--llm-debug-dir <path>` to a single-report or batch command.
+
+- There is no persistent YAML setting for debug capture.
+- The debug root is validated or created before weather collection or provider
+  work. A requested destination that cannot be secured or written is an error.
+- Artifacts are grouped beneath
+  `<path>/<report-id>/<valid-date>/<run-id>/`.
+- Directories and files use owner-only permissions and atomic writes.
+- Debug artifacts may contain rendered messages and content-rich preparation
+  or response diagnostics, but never credentials.
+- The debug path appears in command output only when debug capture is enabled;
+  it is not added to routine durable metadata.
+- Debug artifacts are not cache or comparison inputs. Their retention is owned
+  by the operator who selected the directory.
+
+### Artifact Identities And Versions
+
+Weatherreporter replaces Scriptorium-specific artifact identities rather than
+reusing names whose meanings have changed:
+
+- `PromptPreparationArtifact` uses schema version
+  `weatherreporter.prompt_preparation.v1`, is written as
+  `prompt_preparation.<runID>.json`, and is referenced by
+  `preparationPath`.
+- `PromptExecutionArtifact` uses schema version
+  `weatherreporter.prompt_execution.v1`, is written as
+  `prompt_execution.<runID>.json`, and is referenced by `executionPath`.
+- Run metadata advances to `weatherreporter.metadata.v2` and uses those new
+  path fields.
+
+Preparation files remain beneath the existing configurable `preflight/`
+directory, and execution files remain beneath the existing `snapshots/` tree.
+The stable physical grouping limits deployment disruption without preserving
+misleading Scriptorium-era filenames or field names. Raw generated output,
+normalized generated text, render context, managed Markdown, and other
+artifacts whose meanings have not changed retain their existing names and
+locations.
+
+Run inspection remains able to read `weatherreporter.metadata.v1` and its
+legacy `preflightPath` and `generatedTextResultPath` references. New runs write
+only the v2 metadata and new artifact names; Weatherreporter does not
+dual-write deprecated aliases. CLI summary fields adopt `preparationPath` and
+`executionPath` as an explicit, documented contract change.
+
+## Failure Contract
+
+Status: Implemented design constraints.
+
+- A preparation failure produces a redacted weatherreporter-owned failure
+  receipt with report, RunID, prompt, stage, timing, and classified error
+  context. It does not fabricate Promptkit preparation details.
+- An operational execution failure retains the successful preparation record
+  and adds a redacted execution failure receipt. No partial Promptkit result or
+  model output is invented.
+- A Promptkit validation rejection retains the returned result, raw generated
+  output, validation details, and safe provenance before the report fails.
+- A later generated-text decode, domain-validation, or template failure
+  retains every raw and validated artifact reached before that stage.
+- Caller cancellation takes precedence when the active workflow context is
+  canceled.
+- `promptkit.CapacityError` is recognized with `errors.As`; its backend ID is
+  copied into a weatherreporter-owned capacity error while
+  `ErrCapacityExceeded` remains the classification.
+- Capacity rejection is an operational report failure, not invalid model
+  output, and does not trigger an automatic retry.
+- Other Promptkit public error identities are translated into the narrow
+  weatherreporter error categories needed by CLI, metadata, and batch
+  behavior. Diagnostic prose is not parsed as a contract.
+- Single-report commands return the classified failure with available
+  inspectable paths.
+- Batch runs continue independent later reports under the existing batch
+  failure policy.
+- Any future retry policy belongs to app orchestration, not the adapter.
+
+## Compatibility Requirements
+
+Status: Implemented design constraints.
+
+- Daily, Today, Tomorrow, and Hourly report IDs, prompt IDs, valid periods,
+  artifact grouping, output names, and Distributor bundle behavior remain
+  stable.
+- Morning and evening batch collection, planning, ordering, and continuation
+  behavior remains stable.
+- Module snapshot and Recent Changes behavior remains deterministic.
+- Promptkit receives only the existing curated prompt-input boundary.
+- Managed Markdown remains the Distributor upload source.
+- RunID lookup and inspection remain available for successful and failed runs.
+- Existing managed paths remain stable where their meaning is unchanged.
+  Scriptorium-specific artifact names or schemas change when retaining them
+  would misrepresent the Promptkit contract.
+- Existing v1 run metadata and referenced artifacts remain inspectable after
+  the migration. New runs use the v2 metadata and Promptkit-era artifact
+  identities without dual-writing deprecated aliases.
+- Artifact or metadata schema changes are explicit, documented, and covered by
+  state and inspection tests.
+- Prompt or generated content is not added to routine logs or CLI summaries.
+- Tests do not require live providers or credentials.
+- Removing incomplete three-day, weekend, and storm surfaces is documented as
+  correction of an unfinished product boundary, not as successful Promptkit
+  migration of those reports.
+
+## Verification And Completion Criteria
+
+Status: Completed and verified.
+
+Completion was verified by the following outcomes:
+
+- the four operational reports inspect, prepare, and execute through Promptkit
+  `v0.4.0` using embedded report-owned assets;
+- every report uses exact prompt version `1.0.0`, requires the YAML
+  `data_package`, and declares the expected JSON Schema output contract;
+- prepared execution persists a safe preparation record before provider work
+  and executes the same frozen snapshot;
+- deterministic offline adapter and app tests cover success, preparation
+  failure, credential revalidation, capacity rejection, cancellation, timeout,
+  generation failure, Promptkit validation rejection, generated-text domain
+  failure, template failure, and handle discard;
+- morning and evening batches construct one engine and preserve current
+  collection, planning, ordering, continuation, output, and notification
+  behavior;
+- the temporary corpus has been reconciled into one runtime prompt/schema
+  source without duplicate provider-facing schemas;
+- configuration examples load and contain no Scriptorium fields;
+- CLI summaries and inspection commands expose the new project-owned artifact
+  contract without Promptkit types;
+- Scriptorium code, configuration, tests, and runtime documentation have been
+  removed;
+- incomplete three-day, weekend, and storm commands, registry entries, tests,
+  and current-behavior documentation have been removed or moved to roadmap
+  scope;
+- non-roadmap documentation describes only the implemented Promptkit
+  integration;
+- `go test ./...`, required focused or race-enabled checks, CLI help
+  validation, and `git diff --check` pass; and
+- no committed `go.work`, local `replace`, live-provider test, or
+  secret-bearing fixture remains.
+
+Fixture-based comparison with prior Scriptorium behavior is sufficient.
+Production dual-run is not required because model calls are nondeterministic,
+costly, and difficult to compare meaningfully.
+
+## Decision Status
+
+Status: Completed.
+
+The roadmap has no remaining open product or architecture questions. Later
+changes to this completed scope require new roadmap or decision-record scope
+rather than implicit changes to this historical record.

+# Report Templates
+
+This guide is for maintainers editing Weatherreporter's embedded Markdown
+templates. Templates format already validated report inputs; they do not select
+sources, derive weather facts, or validate generated prose. For those details,
+see [Generated Text internals](internal/generatedtext.md) and [Report Template
+internals](internal/reporttemplate.md).
+
+## Template Assets
+
+Only the generated-text reports use repository-native Markdown templates.
+Each report has one matching template ID, generated-text schema ID, and prompt
+source:
+
+| Report | Template | Schema | Prompt ID and source |
+| --- | --- | --- | --- |
+| Daily | `templates/daily.md.tmpl` (`daily`) | `daily` | `weather.daily_generated_text`; `internal/promptassets/assets/prompts/daily/` |
+| Today | `templates/today.md.tmpl` (`today`) | `today` | `weather.today_generated_text`; `internal/promptassets/assets/prompts/today/` |
+| Tomorrow | `templates/tomorrow.md.tmpl` (`tomorrow`) | `tomorrow` | `weather.tomorrow_generated_text`; `internal/promptassets/assets/prompts/tomorrow/` |
+| Hourly | `templates/hourly.md.tmpl` (`hourly`) | `hourly` | `weather.hourly_generated_text`; `internal/promptassets/assets/prompts/hourly/` |
+
+The matching schemas and Promptkit definitions are embedded by
+`internal/promptassets`. The generated-text catalog pairs each schema ID with
+its template ID; keep the matching prompt definition aligned with that pair.
+
+Shared partials are under `internal/reporttemplate/templates/partials/`:
+
+| Partial | Used by |
+| --- | --- |
+| `alert_digest.md.tmpl` | Daily, Today, Tomorrow, and Hourly |
+| `precipitation_timing.md.tmpl` | Daily, Today, Tomorrow, and Hourly |
+| `daypart_forecast.md.tmpl` | Daily and Tomorrow |
+| `today_daypart_forecast.md.tmpl` | Today |
+
+All shared partials are parsed whenever any top-level template is rendered. A
+syntax error in a partial can therefore prevent every generated-text report
+from rendering.
+
+## Editing Rules
+
+- Use Go `text/template` syntax and keep changes to Markdown structure,
+  ordering, and display conditions.
+- Templates use `missingkey=error`; reference only documented fields and guard
+  optional module pointers with `with` or `if`.
+- Prefer `.Modules` for deterministic display values. Do not add weather
+  calculations, source selection, or prompt-input shaping to a template.
+- Keep generated prose in `.GeneratedText`; do not restate deterministic facts
+  in generated prose merely to compensate for a template change.
+- When changing the generated-prose contract, update the matching prompt,
+  schema, validator, render context, and template together. The validation and
+  catalog rules are owned by [Generated Text internals](internal/generatedtext.md).
+- Use `.Modules.Dayparts` for ordered daypart output. Do not range over
+  `.Modules.DerivedDaypartSummaries`, which is a map.
+
+Minimal optional-value pattern:
+
+```gotemplate
+{{ with .Modules.CurrentConditions }}
+Currently, it is {{ with .TemperatureF }}{{ . }}°F{{ end }}.
+{{ else }}
+Current conditions are unavailable.
+{{ end }}
+```
+
+Minimal list pattern:
+
+```gotemplate
+{{ range .GeneratedText.ForecastDiscussion }}
+{{ . }}
+{{ end }}
+```
+
+## Registered Functions
+
+Templates have these helpers in addition to Go template built-ins:
+
+| Function | Accepts | Returns true when |
+| --- | --- | --- |
+| `hasRelevantAlerts` | an alert-digest value or pointer | its `Relevant` slice is nonempty |
+| `hasEnhancedOrHigherSPCRisk` | an SPC outlook value or pointer | its `RiskDigest` contains an Enhanced, Moderate, or High Risk entry |
+| `isEnhancedOrHigherSPCRisk` | one SPC risk-digest entry | its `LabelText`, or fallback `RiskLabel`, is Enhanced, Moderate, or High Risk |
+
+For example, the alert partial uses the first two functions to decide whether
+to render the section:
+
+```gotemplate
+{{ if hasRelevantAlerts .Modules.AlertDigest }}
+## Alert Digest
+{{ end }}
+```
+
+## Render Context
+
+Every rendered template receives one typed context with these five top-level
+fields:
+
+| Field | Purpose |
+| --- | --- |
+| `.Report` | Display labels and canonical report timing metadata. |
+| `.GeneratedText` | Validated prose supplied by Promptkit. |
+| `.Modules` | Deterministic, typed values prepared for Markdown rendering. |
+| `.Collected` | Normalized upstream facts for advanced use. |
+| `.Derived` | Shared calculated facts for advanced use. |
+
+`.Collected` and `.Derived` are available for an exceptional display need, but
+they are lower-level contracts. Keep reusable weather derivation in Go and use
+the module surface for normal template work.
+
+### Report Metadata
+
+All contexts provide `.Report.Title`, `.Report.GeneratedAt`,
+`.Report.GeneratedAtLabel`, `.Report.ValidPeriod`, and `.Report.Timezone`.
+
+Hourly additionally provides `.Report.LocationName` and
+`.Report.ValidPeriodLabel`.
+
+Daily, Today, and Tomorrow additionally provide `.Report.ForecastDate`,
+`.Report.ForecastDateLabel`, and `.Report.ForecastDayName`. Their valid-period
+field remains canonical timing data; use the supplied display labels instead
+of formatting timestamps in a template.
+
+### Validated GeneratedText Prose
+
+GeneratedText is prose returned by Promptkit and validated before rendering.
+It is not a source for deterministic weather facts.
+
+| Field | Hourly type | Daily, Today, and Tomorrow type | Notes |
+| --- | --- | --- | --- |
+| `.GeneratedText.Summary` | `string` | `string` | Required. |
+| `.GeneratedText.ForecastDiscussion` | `string` | `[]string` | Required; range over the day-style paragraph slice. |
+| `.GeneratedText.PrecipitationTiming` | `string` | `string` | Optional prose used by the precipitation partial when deterministic windows exist. |
+| `.GeneratedText.Confidence` | `string` | `string` | Optional validated prose; the current templates do not render it. |
+
+The JSON schema rejects unknown properties and defines the required fields, but
+the schema body and validation behavior are documented in [Generated Text
+internals](internal/generatedtext.md).
+
+### Deterministic Module Values
+
+Module values are deterministic outputs built from collected and derived facts.
+Module pointers can be nil when their source or policy permits omission.
+
+| Module field | Available in |
+| --- | --- |
+| `.Modules.Metadata`, `.Modules.CurrentConditions`, `.Modules.HourlyForecast`, `.Modules.PrecipTiming`, `.Modules.AlertDigest`, `.Modules.SPCConvectiveOutlooks`, `.Modules.AreaForecastDiscussion`, `.Modules.SPCConvectiveDiscussion`, `.Modules.WeatherStory` | All four contexts |
+| `.Modules.DerivedDailySummary`, `.Modules.DerivedDaypartSummaries`, `.Modules.Dayparts` | Daily, Today, Tomorrow |
+| `.Modules.OutdoorWindows`, `.Modules.DailyPlanning` | Daily |
+| `.Modules.TodayPlanning` | Today |
+| `.Modules.TomorrowPlanning` | Tomorrow |
+
+The repository templates currently use the following nested display values.
+They are the preferred surface for comparable edits:
+
+| Area | Values |
+| --- | --- |
+| Current conditions | `.TemperatureF`, `.ConditionText`, `.ConditionTextLower`, `.ApparentTemperatureF`, `.RelativeHumidityPercent`, `.WindDirectionText`, `.WindSpeedMph` |
+| Hourly periods | `.Periods`, `.HourLabel`, `.Name`, `.TemperatureF`, `.TextDescription`, `.TextDescriptionLower`, `.MentionPrecipitation`, `.ProbabilityOfPrecipitationPercent` |
+| Dayparts | `.Dayparts[].Key` and `.Dayparts[].Summary` fields `DisplayName`, `DominantCondition`, `DominantConditionDisplay`, `TemperatureTrend`, `TemperatureStartPhraseF`, `TemperatureEndPhraseF`, `TemperaturePeakPhraseF`, `TemperatureSteadyPhraseF`, `TemperaturePhraseF`, `MentionPrecipitation`, and `MaxPopPercent` |
+| Precipitation timing | `.PrecipitationWindows`, plus each window's `PeriodBegins`, `PeriodBeginsHourLabel`, `PeriodEnds`, `PeriodEndsHourLabel`, `ExpectationPhrase`, `MaxPopPercent`, `MaxPopTime`, and `MaxPopHourLabel` |
+| Alert digest | `.AlertDigest.Relevant` entries' `Event`, `Headline`, `PeriodBegins`, and `PeriodEnds` |
+| SPC risk digest | `.SPCConvectiveOutlooks.RiskDigest` entries' `LabelText`, `RiskLabel`, `PeriodBegins`, and `PeriodEnds` |
+
+Other fields on these typed modules remain available when a template has a
+well-defined display need. Their module contracts and weather derivation belong
+to [Module contract internals](internal/module.md), [Module builder
+internals](internal/briefing.md), and [Forecast derivation
+internals](internal/forecast-derivation.md).
+
+## Validate Changes
+
+Run the focused checks after editing templates, partials, prompts, or schemas:
+
+```sh
+go test ./internal/reporttemplate ./internal/generatedtext ./internal/app
+git diff --check
+```
+
+The render-context and template tests cover Daily, Today, Tomorrow, and Hourly
+contexts. Run the repository-wide test suite before merging a broader change.

-# Weatherreporter Troubleshooting
+# Troubleshooting
 
-This guide lists recurring failures with likely causes, diagnostics, and safe
-fixes. See [CLI reference](cli.md), [Configuration reference](config.md), and
-[Operations guide](operations.md) for normal usage.
+Keep failed workspace artifacts in place. When a RunID is available, start
+with `weatherreporter inspect metadata RUN_ID` and use the paths in its result.
 
-## `weather_api.base_url is required`
+## Prompt inspection or credentials fail before collection
 
-Symptom: a generation command fails before fetching weather data.
+A prompt/version, contract, selected profile, unsupported direct-key profile,
+or required environment credential can fail before weather collection. Correct
+the configured `promptkit` profile or profile source, confirm the exact
+Promptkit asset is available, and supply any reported environment credential.
+Do not add provider keys to YAML. See [configuration](config.md).
 
-Likely cause: no Weather API base URL is configured.
+## Preparation, capacity, or execution fails
 
-Diagnostic:
+A preparation failure occurs before provider work; an execution failure occurs
+after preparation. Both leave safe provenance and metadata when reached. A
+capacity error for one batch report does not retry that report or prevent later
+independent reports. Inspect the preparation or execution path, correct the
+profile/backend condition, and create a new run. See [operations](operations.md).
 
-```sh
-weatherreporter generate daily --config ./config.yml --date 2026-05-29
-```
+## Generated text fails validation
 
-Safe fix: add `weather_api.base_url` to the config file, or pass the intended
-config path with `--config`.
+Raw generated output may be saved but Markdown is not rendered when the JSON
+does not match the report schema. Correct the Promptkit prompt/profile behavior
+or the matching schema and validator in source control; do not edit raw output
+to treat it as validated. See [templates](templates.md).
 
-Relevant docs: [Configuration reference](config.md).
+## Debug capture fails
 
-## `weather_api.base_url must be an absolute URL`
+`--llm-debug-dir` must be an absolute secure directory outside workspace state.
+A debug-write failure stops the affected report to avoid continuing without the
+requested diagnostic. Repair the named path's ownership or permissions, then
+rerun. Treat capture files as sensitive. See [operations](operations.md).
 
-Symptom: config loading fails with a base URL validation error.
+## Weather, state, output, or notification fails
 
-Likely cause: `weather_api.base_url` is missing a scheme or host.
+Collection errors precede planning. Later filesystem, output-copy, template,
+or Distributor errors retain the reached safe paths in the summary. Repair only
+the reported endpoint or path, leave successful managed reports intact, and
+rerun the affected report or batch. A batch notification is intentionally
+skipped when any report item fails.
 
-Diagnostic: inspect the configured value in the file passed to `--config`.
+## Secrets cannot be loaded
 
-Safe fix: use an absolute URL such as `https://weather.api.example.com/`.
-
-Relevant docs: [Configuration reference](config.md).
-
-## Invalid Timezone
-
-Symptom: config loading fails with `weather_api.timezone` context, or a CLI
-timezone override fails.
-
-Likely cause: `weather_api.timezone` or `--tz` is not recognized.
-
-Diagnostic:
-
-```sh
-weatherreporter generate daily --tz America/Chicago --date 2026-05-29
-```
-
-Safe fix: use an accepted timezone value, such as an IANA timezone name,
-`Chicago`, `Stl`, a US timezone abbreviation, or a UTC offset.
-
-Relevant docs: [Configuration reference](config.md).
-
-## Storm Command Rejects Time Bounds
-
-Symptom: `generate storm` fails with `requires --start`, `requires --end`, or
-`requires --end after --start`.
-
-Likely cause: the manual event window is missing or invalid.
-
-Diagnostic:
-
-```sh
-weatherreporter generate storm --start 2026-05-29T18:00 --end 2026-05-30T06:00
-```
-
-Safe fix: provide both bounds. Use `YYYY-MM-DDTHH:MM` in the configured
-timezone, or RFC3339 timestamps with explicit offsets.
-
-Relevant docs: [CLI reference](cli.md).
-
-## Weather API Fetch Fails
-
-Symptom: generation fails with `fetch /...`, an HTTP status, or request context.
-
-Likely cause: the configured Weather API endpoint is unreachable, returned a
-non-2xx response, or returned an invalid response envelope.
-
-Diagnostic:
-
-```sh
-weatherreporter generate daily --config ./config.yml --date 2026-05-29
-```
-
-Safe fix: verify `weather_api.base_url`, network access, and the Weather API
-service response. The adapter fetches `/observations`, `/conditions/current`,
-`/forecast/hourly`, `/forecast/narrative`, `/alerts/active`, and `/discussion`.
-
-Relevant docs: [Configuration reference](config.md).
-
-## Hourly Forecast Is Missing
-
-Symptom: generation fails with hourly forecast context, such as missing hourly
-data or an hourly forecast containing no periods.
-
-Likely cause: hourly forecast data is required for generated reports.
-
-Diagnostic: check the Weather API response for `/forecast/hourly`.
-
-Safe fix: restore hourly forecast data at the Weather API. Missing-source
-policy cannot make hourly optional.
-
-Relevant docs: [Configuration reference](config.md), [Operations guide](operations.md).
-
-## Source Warnings Appear
-
-Symptom: generation succeeds, but metadata or `inspect sources` shows source
-warnings.
-
-Likely cause: an optional source was missing or malformed under a warning
-missing-source policy.
-
-Diagnostic:
-
-```sh
-weatherreporter inspect sources RUN_ID
-weatherreporter inspect metadata RUN_ID
-```
-
-Safe fix: inspect the warning `source`, `code`, `message`, and `endpoint`. Fix
-the upstream optional source, or intentionally change the relevant
-`missing_source` policy.
-
-Relevant docs: [Configuration reference](config.md), [Operations guide](operations.md).
-
-## `scriptorium` Is Not Found Or Cannot Start
-
-Symptom: generation fails with `run scriptorium render` or `run scriptorium`
-and an executable or OS error.
-
-Likely cause: the configured Scriptorium binary is unavailable or not
-executable.
-
-Diagnostic: check `scriptorium.binary` in config and run the same binary outside
-`weatherreporter`.
-
-Safe fix: install Scriptorium, update `scriptorium.binary`, or fix executable
-permissions.
-
-Relevant docs: [Configuration reference](config.md),
-[Scriptorium integration](integrations/scriptorium.md).
-
-## Render Preflight Fails
-
-Symptom: generation fails with `scriptorium render exited with code ...`.
-
-Likely cause: Scriptorium rejected the prompt, config, profile, or
-`data_package` input before report generation.
-
-Diagnostic:
-
-```sh
-weatherreporter inspect metadata RUN_ID
-weatherreporter inspect data-package RUN_ID
-```
-
-Then read the preflight path from metadata. It contains captured stdout, stderr,
-exit code, and command.
-
-Safe fix: fix the Scriptorium configuration, prompt ID, profile, or data package
-input indicated by stderr.
-
-Relevant docs: [Operations guide](operations.md),
-[Scriptorium integration](integrations/scriptorium.md).
-
-## Scriptorium Run Fails
-
-Symptom: generation fails with `scriptorium run exited with code ...`.
-
-Likely cause: Scriptorium failed during report generation or validation.
-
-Diagnostic:
-
-```sh
-weatherreporter inspect metadata RUN_ID
-weatherreporter inspect data-package RUN_ID
-```
-
-If metadata includes a rendered report path, inspect that report as well. A
-nonzero run can still leave a managed report artifact.
-
-Safe fix: use the captured stderr and data package to fix the Scriptorium
-prompt, profile, model configuration, or validation issue.
-
-Relevant docs: [Operations guide](operations.md),
-[Scriptorium integration](integrations/scriptorium.md).
-
-## Batch Command Returns Nonzero
-
-Symptom: `run morning` or `run evening` returns nonzero.
-
-Likely cause: at least one report in the batch failed.
-
-Diagnostic: inspect stdout for the JSON summary and stderr for compact status
-lines.
-
-Safe fix: use the failed report's artifact paths from the summary, then inspect
-metadata, sources, briefing, and data package for that RunID.
-
-Relevant docs: [CLI reference](cli.md), [Operations guide](operations.md).
-
-## Unknown RunID
-
-Symptom: an inspect command fails with `metadata for run id ... was not found`.
-
-Likely cause: the RunID is mistyped or the command is reading a different
-workspace.
-
-Diagnostic:
-
-```sh
-weatherreporter inspect reports --config ./config.yml --limit 20
-```
-
-Safe fix: copy a RunID from `inspect reports`, or use the same `--config` and
-workspace that generated the report.
-
-Relevant docs: [Operations guide](operations.md).
-
-## Workspace Path Error
-
-Symptom: startup or inspection fails with workspace path validation or
-filesystem read/write context.
-
-Likely cause: a workspace subdirectory is absolute, escapes `workspace.root`, or
-the process cannot read or write the configured path.
-
-Diagnostic: review `workspace.root`, `workspace.snapshots_dir`,
-`workspace.reports_dir`, `workspace.data_packages_dir`, and
-`workspace.preflight_dir`.
-
-Safe fix: keep workspace subdirectories relative to `workspace.root`, and grant
-the process appropriate filesystem permissions.
-
-Relevant docs: [Configuration reference](config.md), [Operations guide](operations.md).
+Secret files must be regular non-symlink files directly beneath
+`secrets.directory` with valid environment-variable basenames. Correct the
+reported file or directory without placing secret values in YAML.
