 # weatherreporter
 
-`weatherreporter` is a Go application for preparing human-facing weather
+Weatherreporter is a Go CLI that turns normalized weather data into managed,
-reports from normalized forecast data. It builds structured briefing packages,
+human-facing Markdown reports.
-runs them through `scriptorium`, and keeps inspectable artifacts under a local
+
-workspace.
+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).

+| `generate tomorrow`, `three-day`, `weekend` | Use their report-defined valid period and accept the common generate flags. |
+| `generate hourly` | Covers the next six hours in the effective report timezone. It does not accept `--date`, `--start`, `--end`, `--hours`, or `--duration`. |

-They do not fetch weather data or invoke `scriptorium`.
 
-## Flags
+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.
 
-- `-h`, `--help`: show help.
+`--quiet` is supported by action commands only. It suppresses action summaries
-- `--config PATH`: load configuration from `PATH` instead of `/usr/local/etc/weatherreporter/config.yml`.
+and routine batch status output; it does not suppress command errors.
-- `--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.
 
-Storm times accept `YYYY-MM-DDTHH:MM` in the configured timezone or RFC3339
+Inspection commands always write their requested JSON value to stdout and do
-timestamps with explicit offsets.

-## Common Workflows
+### Generate Summary
 
-```sh
+A generate summary always identifies the command, report, run, generation
-weatherreporter generate tomorrow --out ./tomorrow.md
+time, valid period, and status:
-weatherreporter generate three-day --out ./three-day.md
+
-weatherreporter generate weekend --out ./weekend.md
+```json
-weatherreporter generate storm --start 2026-05-29T18:00 --end 2026-05-30T06:00 --out ./storm.md
+{
-weatherreporter run morning --out-dir ./reports
+  "command": "generate",
-weatherreporter run evening --out-dir ./reports
+  "reportId": "today",
+  "reportName": "Today Report",
+  "promptId": "weather.today_generated_text",
+  "runId": "20260529T120000.000000000Z_today",
+  "status": "succeeded",

+    "end": "2026-05-30T00:00:00-05:00"
+  }
+}
 ```
 
-## Inspection
+When available, the summary also includes `reportPath`, `metadataPath`,
+`dataPackagePath`, and `preflightPath`. Generated-text reports additionally
+include `generatedTextRawPath`, `generatedTextResultPath`,
+`generatedTextPath`, and `renderContextPath`. `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. |
+| `--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. |
+| `--start TIME`, `--end TIME` | `generate storm` | Required storm-event bounds. |
+| `--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

 ## Field Reference
 
 ### `weather_api`
 
-- `base_url`: absolute base URL for the Weather API. Required for generation and fetch workflows.
+| Field | Default | Rules |
-- `timeout`: HTTP timeout duration. Default: `10s`.
+| --- | --- | --- |
-- `precision`: numeric precision query value. Default: `1`.
+| `base_url` | empty | Absolute Weather API URL. Required for collection and generation. |
-- `units`: Weather API units query value. Default: `us`.
+| `timeout` | `10s` | Must be greater than zero. |
-- `timezone`: report timezone and Weather API timezone query value where supported. Default: `America/Chicago`.
+| `precision` | `0` | Must be zero or greater. Sent as the Weather API precision query value. |
-- `format`: Weather API response format. Must be `json`. Default: `json`.
+| `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` is descriptive prompt context included in briefing metadata and
+`location` supplies descriptive prompt context; it does not choose a Weather
-Scriptorium data packages. It does not select a Weather API endpoint or enable
+API endpoint or configure multiple forecast locations.
-multiple configured forecast locations.
 
-- `id`: short local identifier. Default: `home`.
+| Field | Default |
-- `name`: human-readable location name. Default: `Brentwood`.
+| --- | --- |
-- `region`: broader forecast area context. Default: `St. Louis Metro`.
+| `id` | `home` |
+| `name` | `Brentwood` |
+| `region` | `St. Louis Metro` |
 
-The prompt-facing location object also includes `timezone`, derived from the
+The prompt-facing location timezone is derived from the effective
-effective `weather_api.timezone` after CLI overrides such as `--tz`.
+`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. |

+| `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`,
+and `storm_id`. 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. `storm_id` is
+`{valid_start_stamp}-{valid_end_stamp}` for Storm Report and empty otherwise.
+
+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` |

+# Development
+
+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, invokes Scriptorium for
+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.
+
+## What To Read
+
+| When working on | Read | Why |
+| --- | --- | --- |
+| Product behavior or the shortest useful workflow | [README](../README.md), [CLI reference](cli.md), and [operations guide](operations.md) | These own product orientation, invocation, and normal operation. |
+| Application shape, package boundaries, dependency direction, safety properties, or architectural invariants | [Architecture policy](policy/architecture.md) and relevant ADRs under `docs/adr/`, when present | Architecture defines the intended system; ADRs preserve significant decision rationale. |
+| Any documentation addition, revision, move, or removal | [Documentation policy](policy/documentation.md) | It defines canonical owners, audience boundaries, current-state rules, and document lifecycle. |
+| Adding, changing, reviewing, or deleting tests | [Testing policy](policy/testing.md) and focused package tests | The policy defines risk-based sufficiency, durable test boundaries, doubles, and test-maintenance criteria. |
+| CLI commands, flags, output, quiet mode, or command wiring | [CLI reference](cli.md) and [CLI internals](internal/cli.md) | The reference owns the user contract; the internal guide owns command composition and output flow. |
+| Configuration fields, defaults, loading, overrides, validation, or secrets | [Configuration reference](config.md), [architecture policy](policy/architecture.md), and tests under `internal/config` | These separate the user-visible contract, architectural rules, and executable behavior. |
+| Top-level generation, batch, collection, inspection, or notification workflow | [App orchestration internals](internal/app-orchestration.md) | It owns workflow ordering, persistence points, failure propagation, and orchestration invariants. |
+| Weather API transport, source envelopes, source warnings, or collection | [Weather API integration](integrations/weatherapi.md), [weather-data internals](internal/weather-data.md), and [collection internals](internal/collect.md) | These separate the external contract, normalized source facts, and app-facing collection behavior. |
+| Forecast periods, weather derivation, collected facts, or derived facts | [Forecast derivation internals](internal/forecast-derivation.md) and [fact contracts](internal/facts.md) | They own deterministic derivation and the fact boundaries used by reports. |
+| Report definitions, valid periods, report IDs, output naming, or batch composition | [Report registry internals](internal/report-registry.md) and [app orchestration internals](internal/app-orchestration.md) | Report definitions own selection and period rules; orchestration owns execution. |
+| Module IDs, module composition, briefing values, or prompt-facing exports | [Module contract internals](internal/module.md), [module builder internals](internal/briefing.md), and [prompt-input internals](internal/prompt-input.md) | These own module contracts, value construction, and the curated prompt-package boundary. |
+| Recent Changes comparison | [Changes internals](internal/changes.md) and [operations guide](operations.md) | The internal guide owns structured comparison; operations owns user-visible artifact behavior. |
+| Scriptorium commands, subprocess execution, prompt inputs, or result handling | [Scriptorium integration](integrations/scriptorium.md), [Scriptorium adapter internals](internal/scriptorium-adapter.md), and [prompt-input internals](internal/prompt-input.md) | These separate the external CLI contract, subprocess boundary, and input construction. |
+| Generated-text schemas, validation, render contexts, templates, or Markdown rendering | [Generated-text internals](internal/generatedtext.md), [report-template internals](internal/reporttemplate.md), and [report template guide](templates.md) | These own structured text, renderer implementation, and the maintainer-facing template surface. |
+| Workspace paths, metadata, atomic persistence, lookup, inspection, or recovery | [State internals](internal/state.md), [operations guide](operations.md), and [troubleshooting guide](troubleshooting.md) | These separate implementation, operator workflows, and symptom-based recovery. |
+| Distributor bundles, uploads, notification artifacts, or failures | [Distributor adapter internals](internal/distributor-adapter.md), [Distributor integration contracts](integrations/distributor/), and [operations guide](operations.md) | These separate adapter behavior, external contracts, and operational lifecycle. |
+| Maintained example configuration | [Configuration reference](config.md) and files under `examples/` | The reference owns field meaning; examples own complete copyable files. |
+| Proposed, deferred, or unimplemented work | Documents under `docs/roadmap/` | Future behavior and implementation status belong only in roadmaps until implemented. |
+
+For an existing subsystem, inspect its focused internal document, package-local
+types, and tests before changing behavior. Use the package boundaries already
+present before introducing a new package or abstraction.
+
+## Repository Map
+
+| Area | Responsibility |
+| --- | --- |
+| `cmd/weatherreporter` | Binary entry point. |
+| `internal/cli` | Command parsing, flags, help, output, and command wiring. |
+| `internal/app` | Generation, batches, collection coordination, notification, and inspection orchestration. |
+| `internal/config` | Configuration defaults, loading, precedence, secrets, and validation. |
+| `internal/adapters` | Weather API, Scriptorium, and Distributor boundaries. |
+| `internal/weatherdata`, `internal/forecast`, `internal/facts` | Normalized source facts and deterministic derivation. |
+| `internal/report`, `internal/module`, `internal/briefing`, `internal/changes` | Report registry, module contracts and values, and structured comparison. |
+| `internal/promptinput`, `internal/generatedtext`, `internal/reporttemplate` | Prompt packages, generated-text validation, render contexts, and Markdown templates. |
+| `internal/state`, `internal/fileutil`, `internal/timeutil` | Durable artifacts, atomic file operations, clocks, dates, timezones, and periods. |
+| `docs` | User, operator, integration, internal, policy, and roadmap documentation. |
+| `examples` | Maintained copyable configuration. |
+
+The [architecture policy](policy/architecture.md) is authoritative for
+normative boundaries. Focused documents under `docs/internal/` own detailed
+implemented subsystem behavior.
+
+## Contributor Workflow
+
+1. Read the documents and focused tests identified by the task guide.
+2. Use focused package checks while iterating.
+3. Run `gofmt -w` on changed Go files.
+4. Update the canonical documentation and maintained examples in the same
+   change when behavior changes.
+5. Run repository-wide validation before considering the work complete.
+
+Preserve actionable error context, keep secrets out of logs and fixtures, and
+avoid validation that requires live Weather API, Scriptorium, or Distributor
+services. The architecture and testing policies own the detailed rules.
+
+## Baseline Validation
+
+Run:
+
+```sh
+go test ./...
+go run ./cmd/weatherreporter --help
+git diff --check
+```
+
+Use focused package tests during development and add broader or race-enabled
+checks when required by the [testing policy](policy/testing.md) and the risks of
+the change.

+# 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.

+3. `--profile <profile>` when `scriptorium.profile` is set.

-Report generation:
+`render` is the preflight command. `run` writes either a Markdown report or a
+raw generated-text artifact to the supplied `--out` path. The structured
+generated-text use of `run` has the same argv as Markdown generation; it does

-This document describes the implemented workflow coordinator in `internal/app`.

-## Purpose
+workflow ordering, request composition, partial-result handling, and the
-
+application-facing interfaces used for tests.
-`internal/app` coordinates the top-level use cases after CLI parsing and config

 ## Inputs And Outputs
 
-Inputs:
+The package accepts generate, resolved-report, batch, explicit-collection, and

-Outputs:
+Exact public command syntax, configuration fields, workspace layout, external
+protocols, and report definitions belong in [the CLI reference](../cli.md),

-## Config Fields Used
+Direct-Markdown reports prepare the managed report and invoke the Scriptorium
+run boundary. Generated-text-template reports look up their catalog definition,
+run structured Scriptorium output to the raw artifact, preserve any structured
+run result, validate and save generated text, build and save a render context,
+then render the embedded Markdown template. Schema, template, and subprocess

-Single-report generation follows this order:
+After report generation, the batch notifier is considered once. It is omitted

 # 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

+[state internals](state.md).

+`Thresholds`. A `Change` has a stable type and message plus previous and

+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

-Outputs:
+For daily comparison, `alert_digest` and `precip_timing` are optional: alerts
+are compared when present, and timing is compared only when both snapshots

+# CLI Internals
+
+`internal/cli` turns process arguments into application requests and translates
+application results into terminal output. The user-facing command, flag, and
+output contract belongs in the [CLI reference](../cli.md).
+
+## Responsibilities
+
+`Runner.Run` dispatches the top-level action or inspection request. For actions,
+the package parses command-specific and common flags, loads configuration with
+CLI overrides, obtains the current time, and constructs either an
+`app.GenerateRequest` or an `app.BatchRequest`. It delegates generation and
+batch execution to `internal/app`.
+
+For inspection, it loads configuration, builds the appropriate app inspection
+request, and writes the returned value. Inspection is read-only; the inspected
+artifact types and user invocation remain owned by the [CLI reference](../cli.md)
+and [operations guide](../operations.md).
+
+## Result Translation
+
+Action results become CLI-safe JSON summaries in `result.go`. Generate summaries
+carry report identity, status, relevant artifact paths, and notification
+summary data. Batch summaries carry aggregate counts, per-report outcomes, and
+the optional batch notification result. The translation deliberately excludes
+full module snapshots, prompt packages, raw generated text, Scriptorium output,
+and complete Distributor payloads.
+
+When an action returns both a result and an error, the CLI writes the failed
+summary before returning that error. Parse, configuration-load, and other
+failures that produce no application result return without a summary.
+
+`writeActionResult` writes action status information to stderr first, then JSON
+to stdout. Batch execution supplies the status writer; single-report generation
+does not emit routine stderr output. Quiet action requests suppress both normal
+streams but still return errors. Inspection writes its JSON value to stdout and
+does not accept quiet mode because stdout is the inspection result.
+
+## Boundaries
+
+The package owns argument parsing, request adaptation, help text, and terminal
+presentation. It does not implement report selection, collection, state
+persistence, external transport, subprocess execution, or notification policy.
+Those concerns remain in [application orchestration](app-orchestration.md) and
+their focused owners.
+
+## Failure Behavior
+
+- Invalid command names, flags, dates, and configuration fail before an app
+  request is executed.
+- Application errors retain their application context; output helpers do not
+  hide or replace them.
+- JSON-encoding errors are returned directly.
+- A failed batch summary causes the CLI to return an aggregate batch error even
+  when the detailed batch call has already returned its result.
+
+## Tests And Invariants
+
+Focused tests are in `internal/cli/root_test.go`, `internal/cli/output_test.go`,
+and `internal/cli/result_test.go`.
+
+- CLI summaries are stable, bounded views of app results.
+- Routine batch status lines precede the batch JSON summary.
+- A quiet action produces no successful or failure summary output.
+- Inspection never invokes action-output helpers.

+# Collection Internals
+
+`internal/collect` is the application-facing boundary for collecting the
+normalized Weather API bundle. The external HTTP contract belongs in the
+[Weather API integration guide](../integrations/weatherapi.md); normalized data
+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}`.
+
+The package wraps adapter construction failures as weather-collection setup
+errors and fetch failures as bundle-collection errors. It does not retry,
+persist, select reports, derive facts, build modules, invoke Scriptorium, or
+notify Distributor.
+
+## Application Composition
+
+`internal/app` owns the narrow `Collector` interface used by workflow tests;
+the production implementation delegates to `collect.Run`. Generation, batch
+execution, and explicit bundle fetching all use this boundary. Application
+orchestration rejects a nil collector result or a nil bundle before report work
+can continue.
+
+Single-report generation and a batch each collect once. A batch passes the same
+normalized collection to planning and to every report it generates. Collection
+failure prevents later workflow work for that request.
+
+## Boundaries And Invariants
+
+Collection owns adapter creation and retrieval of one normalized bundle. It
+must not make report, period, batch, prompt, module, filesystem, or notification
+decisions.
+
+- App-facing Weather API collection always passes through this package.
+- The returned value is normalized source data, not facts or prompt input.
+- Context cancellation is passed to the Weather API adapter.
+- Errors retain whether setup or fetching failed.
+
+Focused tests are in `internal/collect/collect_test.go`; orchestration use is
+also covered by `internal/app/app_test.go`.

+# 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

+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.
+
+## Verification
+
+Focused tests cover configuration validation, request mapping, timeouts and
+polling, status translation, conflict handling, and token redaction:

+go test ./internal/adapters/distributor

+# 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 |
+| Three-day, Weekend | One clipped daily summary for each overlapping local day |
+| Storm | One summary for the explicit report window |
+
+`DaypartSummaries` is collected from the resulting daily or storm 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 and storm behavior, daily and partial-day 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.

+`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
+
+Only the Daily, Today, Tomorrow, and Hourly report definitions use the
+generated-text-template mode. `LookupDefinition` rejects a direct-Markdown
+definition, 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 schema, 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

+packages, raw Scriptorium output, state persistence, and template asset lookup

+# 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 |
+| Three-day and Weekend | metadata, current conditions, daypart summaries, precipitation timing, alert digest, SPC outlooks, AFD, SPC discussion, weather story, outdoor windows |
+| Storm | metadata, current conditions, precipitation timing, alert digest, SPC outlooks, AFD, 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.

+# Report Template Internals

+`internal/reporttemplate` embeds and renders the repository's native Markdown
+templates and exposes their companion generated-text schemas. The current asset
+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, shared partials, and JSON schemas from
+its asset directories. `Template` and `Schema` return the requested embedded
+asset and fail with the requested ID when it is unknown or unreadable.
+
+Generated-text catalog handlers obtain schema bytes and template source through
+these APIs. Prompt source files are repository assets for prompt registration;
+they are not reporttemplate lookup assets. 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
+Scriptorium, or upload reports. It produces Markdown bytes for application
+orchestration to persist.
+
+Focused tests cover asset lookup, schema availability, rendering, partial
+behavior, missing keys, and malformed context:
+
+```sh
+go test ./internal/reporttemplate
+```
+
+Embedded assets stay as separate files, shared fragments stay under the partial
+directory, and generated-text schemas describe prose slots rather than
+deterministic weather facts.

+Scriptorium process arguments and translates process results back to local
+types. The external CLI and output contract belongs to the
+[Scriptorium integration guide](../integrations/scriptorium.md); prompts,
+template inputs, and report ownership remain outside this adapter.
 
-## Purpose
+## Request-to-command translation
 
-The adapter runs `scriptorium render` for prompt preflight and `scriptorium run`
+`Runner` accepts a binary, config path, profile, timeout, extra arguments, and
-for Markdown report generation. It isolates subprocess execution, argv
+an injectable command executor. Its defaults are the `scriptorium` binary and
-construction, timeout handling, output capture, and exit-code interpretation
+the real `ExecRunner`. Optional configuration flags are placed before the
-from app and domain packages.
+operation-specific arguments, and extra arguments are appended last.
 
-## Inputs And Outputs
+| Local operation | Required values | Translated arguments |
+| --- | --- | --- |
+| `Render` | prompt ID, data-package path | `render [--config …] [--profile …] --prompt <id> --input data_package=<path> --format json [extra …]` |
+| `Run` | prompt ID, data-package path, output path | `run [--config …] [--profile …] --prompt <id> --input data_package=<path> --out <path> [extra …]` |
+| `StructuredRun` | prompt ID, data-package path, output path | Same translation as `Run` |
 
-Inputs:
+Blank required values fail before a command starts. The adapter does not add
+schema flags or interpret a prompt's payload; it only gives Scriptorium the
+named `data_package` input.
 
-- prompt ID
+## Command execution and result translation
-- prompt input data package path
-- report output path for `run`
-- configured binary, config path, profile, timeout, and extra arguments
-- context for cancellation
 
-Outputs:
+`ExecRunner` uses `exec.CommandContext`, never a shell. A positive configured
+timeout creates a child context. Standard output and standard error are
+captured independently, each with a 1 MiB limit, and the executed command is
+retained for diagnostics.
 
-- argv used for execution
+`RenderResult`, `RunResult`, and `StructuredRunResult` expose the command,
-- captured stdout and stderr
+captured output, truncation markers, and exit code. Run results also retain the
-- truncation flags for captured output
+requested output path. Exit status zero is successful. A nonzero process exit
-- exit code
+returns its result and an error, while a start failure, cancellation, or
-- report output path for `run`
+deadline failure returns no result and the execution error.
 
-## Boundaries
+The adapter does not parse rendered JSON, validate a generated report, write
+state, or upload a report. Those responsibilities sit with
+[application orchestration](app-orchestration.md), [state internals](state.md), and the
+relevant delivery adapter.
 
-`internal/adapters/scriptorium` owns Scriptorium command construction and
+## Verification
-subprocess execution. It does not choose report types, build prompt input,
-fetch weather data, decide workflow order, or persist workflow metadata.
 
-The adapter exposes request and result structs for render and run operations.
+Focused tests cover argument order, validation, bounded capture, timeout and
-State persistence uses a state-owned preflight artifact shape; app
+cancellation handling, and exit-status translation:
-orchestration converts render results before saving.
 
-## Config Fields Used
+```sh
-
+go test ./internal/adapters/scriptorium
-- `scriptorium.binary`
-- `scriptorium.config_path`
-- `scriptorium.profile`
-- `scriptorium.timeout`
-- `scriptorium.extra_args`
-
-## Commands
-
-Render preflight argv starts with:
-
-```text
-scriptorium render --prompt <prompt_id> --input data_package=<path> --format json
 ```
-
-Report generation argv starts with:
-
-```text
-scriptorium run --prompt <prompt_id> --input data_package=<path> --out <path>
-```
-
-Configured `--config` and `--profile` flags are inserted after the subcommand
-and before prompt-specific arguments. Extra arguments are appended after the
-built-in arguments.
-
-## Execution Behavior
-
-The adapter runs commands without shell interpolation. The same private
-execution path is used by render and run after command-specific request
-validation and argv construction.
-
-When `scriptorium.timeout` is greater than zero, each subprocess call uses a
-context with that timeout. Stdout and stderr are captured separately, capped at
-1 MiB each, and marked as truncated when the cap is reached.
-
-## Failure Behavior
-
-- Missing prompt ID or data package path returns an error before subprocess
-  execution.
-- Missing run output path returns an error before subprocess execution.
-- Subprocess start errors, context cancellation, and timeouts are wrapped with
-  operation context by the caller-facing method.
-- Nonzero render and run exits return the captured result plus an error
-  containing the exit code and stderr.
-
-## Tests
-
-Inspect:
-
-- `internal/adapters/scriptorium/runner_test.go`
-- `internal/app/app_test.go`
-- `internal/cli/root_test.go`
-
-## Invariants
-
-- No shell interpolation is used.
-- The Scriptorium input name is `data_package`.
-- Render and run preserve command-specific result structs.
-- Scriptorium-specific flags stay inside adapter and config boundaries.

 # State Internals
 
-This document describes filesystem state in `internal/state`.
+The `internal/state` package owns filesystem-backed run state: safe path
+derivation, metadata persistence, prior-report lookup, and read-only report
+inspection. It does not decide which reports to generate or deliver. For the
+operator-facing layout and retention procedures, see the
+[operations guide](../operations.md).
 
-## Purpose

-`internal/state` owns managed workspace paths, atomic JSON writes, persisted
+`NewFilesystemStore` requires a workspace root and rejects absolute or

+escaping values for every configured state directory. `Paths` then validates a
+run ID and artifact group before deriving all paths from the report's valid
+start date (`YYYY-MM-DD`). This keeps a run's artifacts together while making
+the paths safe to use below the configured workspace.
 
-## Inputs And Outputs
+| Artifact | Derived location |
+| --- | --- |
+| Module snapshot | `snapshots/<group>/<date>/modules.<run-id>.json` |
+| Metadata | `snapshots/<group>/<date>/metadata.<run-id>.json` |

-Inputs:
+The configured notification root separates notification artifacts from report
+artifacts; single-report notification paths use the report's valid date. Report
+producers create parent directories as needed and write the report body; state
+is responsible for the surrounding paths and saved run artifacts.

+`Metadata` is the durable inventory for a run. It records its schema version,

-- metadata JSON path
-- prior comparable snapshot metadata

-- recent report records for inspection
 
-## Boundaries
+`BuildMetadataFromBriefingMetadata` establishes the common fields; the
+application adds locations as artifacts are produced. `SaveMetadata` requires
+the run ID and the module snapshot, data-package, preflight, and metadata
+paths. The package also saves module snapshots, data packages, preflight
+records, generated-text artifacts, render contexts, and notifications. JSON
+writes use `fileutil.WriteJSONAtomic`, so readers do not observe a partially
+written state file.

-## Config Fields Used
+`FindPriorSnapshot` searches metadata rather than guessing from filenames. It
+only considers an earlier compatible report in the same artifact group and
+supports the comparison strategies defined by the report request:
 
-- `workspace.root`
+- `same_valid_date` finds an earlier generated report for the same valid day.
-- `workspace.snapshots_dir`
+- `weekend_window` finds a prior comparable weekend window.
-- `workspace.reports_dir`
-- `workspace.data_packages_dir`
-- `workspace.preflight_dir`
 
-Workspace subdirectories must be relative paths that stay under
+The newest eligible metadata record wins; the current run is excluded.
-`workspace.root`.
+Unreadable or malformed candidate metadata is ignored so a damaged historical
+record does not block a new run.
 
-## Managed Layout
+`ListReports` walks saved metadata, returns results ordered newest-first by
+generation time, and treats a missing snapshots directory as an empty history.
+`LoadMetadataByRunID` builds on that inspection path. These APIs are read-only;
+repairing or pruning stored state is an operational concern.
 
-Paths are derived from the resolved report definition's artifact group, the

-- Storm Report currently has no prior lookup because explicit event-window

-
-## Writes And Inspection
-
-Durable JSON writes use shared atomic file helpers. Managed Markdown reports are
-prepared by creating their parent directory; Scriptorium writes the report body
-to the prepared path. Extra Markdown copies are handled by app orchestration.
-
-Inspection helpers read existing metadata, briefing, and data package files.
-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.
-
-## Tests
-
-Inspect:
-
-- `internal/state/filesystem_test.go`
-- `internal/app/app_test.go`

-## Invariants
-
-- Managed paths stay under the configured workspace root.
-- Artifact grouping comes from report definitions.
-- 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
+`Bundle` has a collection timestamp (`FetchedAt`), source provenance
-configured Weather API endpoint and assembles the bundle consumed by forecast
+(`Sources`), and collection-level warnings (`Warnings`). Its product fields are

-conditions and weather story context when those sources are available.
+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.

-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.

-## 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
+```sh
-
+go test ./internal/weatherdata
-See [Weather API integration](../integrations/weatherapi.md) for the external
+go test ./internal/adapters/weatherapi
-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. Successful `data: null` responses from `/alerts/active`
-represent a checked empty active-alert list, not a missing source.
-`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.
-- Explicit `data: null` from `/alerts/active` produces an empty, non-missing
-  alert run.
-
-## 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.

+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

-```
+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:

-# 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
+This policy defines Weatherreporter's system shape, normative ownership,
-`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.
+dependency direction, architectural invariants, safety properties, and
+non-goals. Developers and coding agents should use it to preserve the
+application's boundaries as the implementation evolves.
 
-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.
+The [development guide](../development.md) owns the current package inventory
+and contributor workflow. Focused documents under `docs/internal/` own
+implemented subsystem mechanics. This policy owns the rules those packages and
+mechanics must preserve.
 
-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.
+## System Shape
 
-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.
+Weatherreporter is a deterministic weather briefing and report-preparation CLI.
+It consumes normalized weather data, derives report facts and module snapshots,
+builds curated prompt packages, compares structured snapshots with prior runs,
+and invokes Scriptorium either to produce managed Markdown directly or to
+produce bounded generated-text prose for repository-owned templates. It
+persists inspectable artifacts and can upload completed reports through
+Distributor.
 
-`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.
+The application is intentionally a small, explicit, dependency-light Go
+program. Add abstraction only when it protects a real boundary, makes an
+important invariant testable, or supports an implemented extension point.
 
-## Project Shape
+The primary flow is:
 
-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.
+1. CLI parsing and configuration resolution;
+2. report or batch resolution;
+3. normalized weather collection;
+4. deterministic fact derivation and module construction;
+5. structured prior-snapshot comparison;
+6. curated prompt input and report-mode-specific Scriptorium processing;
+7. generated-text validation when applicable, managed Markdown production,
+   and metadata persistence; and
+8. optional notification using managed report artifacts.
 
-Business/domain logic should live outside CLI, transport, and external-adapter packages.
+Inspection is a separate read-only flow over persisted state. It must not
+collect weather data, invoke Scriptorium, or upload reports.
+
+## Ownership And Dependency Direction
+
+### Entry Point And CLI
+
+The binary entry point should do no business work beyond constructing and
+running the CLI. CLI code owns commands, arguments, flags, help, output
+formatting, and conversion into application requests.
+
+CLI packages must not own meteorological decisions, report composition,
+artifact layout, Recent Changes comparison, external transport, or subprocess
+construction.
+
+### Configuration
+
+Configuration loading, built-in defaults, overrides, secret loading, and
+validation belong to `internal/config`. Operational values shared across
+packages must be explicit configuration or constants owned by the responsible
+package, not hidden in CLI or adapter code.
+
+The exact configuration contract belongs in the
+[configuration reference](../config.md). Other architecture documents should
+state ownership and safety rules rather than repeat fields, defaults, or
+precedence.
+
+### Application Orchestration
+
+`internal/app` owns top-level use cases and workflow order. It composes report
+resolution, collection, domain transformations, state, rendering, and optional
+notification through narrow project-owned contracts.
+
+The application layer may coordinate components and convert between their
+contracts. It must not absorb CLI parsing, HTTP transport, subprocess argument
+construction, filesystem layout, weather derivation algorithms, template
+execution, or adapter-specific dependency types.
+
+### Domain And Report Logic
+
+Meteorological selection, forecast-period resolution, daypart grouping,
+threshold detection, fact derivation, report composition, module construction,
+generated-text validation, and Recent Changes comparison belong in deterministic
+Go domain packages.
+
+Domain packages must not depend on CLI parsing, process execution, remote
+transport, or concrete external-library types. Given the same normalized
+inputs, configuration, valid period, prior snapshot, and clock, domain behavior
+should be reproducible.
+
+Report selection must go through the report registry or an equivalent
+centralized mechanism. A report definition owns its identity, prompt and
+rendering mode, valid-period resolver, module composition, comparison strategy,
+artifact grouping, and output naming. Do not scatter report-ID conditionals
+through CLI, orchestration, or adapters.
+
+### External Adapters
+
+External integrations use adapter boundaries under `internal/adapters`.
+Adapters own transport and protocol mechanics; application and domain packages
+own decisions.
+
+- The Weather API adapter owns HTTP request construction, timeouts, retries,
+  response-envelope handling, decoding, and endpoint compatibility.
+- The Scriptorium adapter owns argument construction, context-aware subprocess
+  execution, stdout and stderr capture, exit interpretation, and result
+  decoding. It must avoid shell interpolation.
+- The Distributor adapter owns dependency-specific bundle and upload types,
+  client construction, request execution, status handling, and redaction.
+
+External dependency types must not leak beyond the adapter that integrates
+them. Adapters should expose narrow project-owned inputs and outputs so an
+integration can be tested or replaced without changing domain logic.
+
+### State And Embedded Assets
+
+`internal/state` owns managed workspace paths, durable metadata, atomic
+artifact persistence, prior lookup, and inspection reads. Other packages should
+request state operations rather than reconstruct managed paths independently.
+
+Schemas, prompts, Markdown templates, and partials should live as separate
+repository assets and be embedded by the package that owns their execution or
+lookup. Keep weather derivation and path construction out of templates.
+
+## Architectural Invariants
+
+### Weather Truth And Generated Text
+
+- Normalized source data and deterministic Go derivation are authoritative for
+  weather facts.
+- LLM prompts receive curated module-based packages rather than raw,
+  unbounded source payloads.
+- For generated-text-template reports, generated text is limited to defined
+  prose slots, validated before use, and rendered through typed or otherwise
+  explicit contexts.
+- Direct-Markdown reports receive the same curated prompt-package boundary but
+  produce managed Markdown directly through Scriptorium rather than the
+  generated-text schema and repository-template workflow.
+- Repository-owned templates arrange validated prose and deterministic facts;
+  they do not perform meteorological derivation.
+
+### Reports And Comparison
+
+- Report behavior is resolved through centralized definitions.
+- Recent Changes is computed from structured module snapshots, never by
+  comparing rendered Markdown.
+- Batch workflows collect normalized weather data once and reuse that
+  collection for planning and report generation.
+- Report metadata links identity, generation time, valid period, source
+  provenance, and the managed artifacts produced for the run.
+
+### Managed State And Notification
+
+- Durable structured writes are atomic where practical.
+- Managed paths remain beneath the configured workspace root.
+- Operations that delete, move, overwrite, or copy files use narrow, explicit
+  paths; destructive cleanup is opt-in.
+- Intermediate artifacts reached before a later failure remain inspectable
+  where practical.
+- Distributor uploads use managed Markdown reports, never optional output
+  copies or broad workspace scans.
+- Notification occurs only after the managed report and required metadata have
+  been successfully produced.
+
+### Security, Errors, And Cancellation
+
+- Secrets must not appear in logs, errors, persisted artifacts, examples, or
+  user-facing output.
+- Errors preserve actionable operation, report, RunID, path, endpoint, or
+  subprocess context without exposing secrets or unnecessarily large payloads.
+- External calls, subprocesses, storage operations, and multi-step workflows
+  accept or propagate `context.Context` where cancellation or timeout is
+  meaningful.
+- Adapter failures preserve useful status, stderr, or response context at the
+  boundary and are translated into project-owned errors before crossing into
+  unrelated packages.
 
 ## Dependency Policy
 
-Prefer the Go standard library where practical.
+Prefer the Go standard library. Add an external dependency only when it
+materially improves correctness, security, interoperability, or
+maintainability. A dependency used for a small convenience does not justify its
+lifetime upgrade and compatibility cost.
 
-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.
+Keep dependency-specific types inside the package that intentionally adopts
+the dependency. The application should remain understandable and testable
+without requiring framework-wide abstractions or live external services.
 
-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.
+## Verification And Documentation
 
-## Package Layout
+Core behavior must be testable without live Weather API, Scriptorium, or
+Distributor services. The [testing policy](testing.md) owns test philosophy,
+sufficiency, boundaries, and test-double guidance.
 
-Use this layout unless the project has a documented reason to differ:
+Documentation must follow the
+[documentation policy](documentation.md). Update the canonical user,
+operator, integration, internal, and example documentation in the same change
+as the behavior it describes. Future or proposed behavior belongs under
+`docs/roadmap/`; significant durable decisions may be recorded as ADRs.
 
-- `internal/app`: application orchestration and top-level use cases.
+## Non-Goals
-- `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.
+Weatherreporter is not:
 
-## Configuration
+- a source weather-data ingestion or normalization service;
+- a general-purpose LLM orchestration framework;
+- an application in which an LLM selects authoritative weather facts or report
+  policy;
+- a plugin framework with dynamically discovered report or module behavior;
+- an HTTP service or multi-user distributed job system;
+- a replacement for Scriptorium or Distributor protocol ownership; or
+- a system that hides operational state exclusively inside opaque logs or
+  remote services.
 
-Centralize configuration loading, processing, precedence, defaults, and validation in `internal/config`.
+New requirements may justify revisiting a non-goal. A change that alters system
-
+shape, dependency direction, a safety property, or another architectural
-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`.
+invariant should be recorded deliberately in this policy or an ADR rather than
-
+introduced implicitly.
-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.

-# 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/fileutil`: shared atomic filesystem write and copy helpers.
-- `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:
+This policy assigns each Weatherreporter documentation topic to one canonical
-
+owner. Its goal is to keep documentation accurate, concise, discoverable, and
-1. users who need to run the application;
+resistant to drift for users, operators, developers, integrators, maintainers,
-2. administrators/operators who need to configure and operate it;
+and coding agents.
-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.
 
 ## Core Rules
 
-### 1. Keep docs concise
+### One Canonical Documentation Owner
-
+
-Each document should cover a defined scope and only the essentials for that scope.
+Each authoritative fact belongs in one canonical document or documentation
-
+area. A non-owning document may give a short, stable summary for orientation,
-Avoid:
+but it must link to the canonical owner instead of maintaining a second

+definition.
-- repeated reference material;
+
-- implementation detail in user-facing docs;

-- verbose examples where one minimal example is clearer.

+in this policy.
-
+
-Unimplemented, planned, aspirational, experimental, or future work may be described only under:
+Executable sources of truth and documentation owners serve different purposes.
-
+Code, schemas, and embedded assets determine runtime behavior. The canonical
-- `docs/roadmap/`
+document owns the corresponding explanation or reference for readers. Both may
-
+necessarily express the same contract, but other documentation should summarize
-No other documentation file, including `README.md`, should describe code, features, modules, stages, commands, config fields, or behaviors that do not currently exist.
+and link rather than create another complete reference. When implementation and
-
+documentation disagree, verify the intended behavior and update them together.
-If a feature is partial, non-roadmap docs may describe only the implemented portion and its current boundary.
+
-
+### Current State, Decisions, And Future Work
-### 3. Use canonical homes
+
-
+Outside `docs/roadmap/`, documentation describes implemented behavior only.
-Each type of information should have one canonical location.
+Partial features may be described only to their implemented boundary.
-
+
-Canonical homes:
+An accepted architecture decision may describe an approved direction before it
-
+is implemented, but acceptance is not evidence that the behavior exists.

+
-- operations and recovery: `docs/operations.md`
+### Audience And Detail

+

+Write for the document's stated audience and include only the detail needed for
-- future work: `docs/roadmap/`

-- contributor workflow: `docs/policy/development.md`
+implementation detail. Developer documentation should link to user-facing and
-- copyable examples: `examples/`
+external contracts instead of restating them.
-
+
-Other files should summarize briefly and link to the canonical source.
+### Links
-
+
-### 4. Keep examples real
+Use descriptive link text and repository-relative links for repository
-
+documents. Link to the canonical owner rather than to a duplicate summary.
-Examples should be valid, maintained, and free of secrets.
+Check every added or changed link, and repair or remove links when their target
-
+moves or is retired.
-Where practical:
+
-- example configs should load successfully;
+### Examples And Code Fences
-- example commands should match real CLI syntax;

-## 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;

-- 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.

+# 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, subprocesses, 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, Scriptorium, 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, subprocess, 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 Scriptorium, 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 command runners for Scriptorium 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.

+- durable upload retry queues
+- distributor-specific CLI flags
+- distributor workspace scanning
+- destination routing, Markdown-to-HTML transformation, public URLs, or nginx

+# Promptkit Migration Roadmap
+
+Status: Accepted migration policy; the migration itself is unimplemented.
+
+## Purpose
+
+This roadmap defines the scope and desired end state for replacing the
+external Scriptorium CLI integration with the Promptkit Go library. The
+migration is not yet implemented. Current Scriptorium behavior remains
+documented in the [Scriptorium integration guide](../integrations/scriptorium.md)
+until the replacement is complete.
+
+A separate staged implementation plan will describe how to move from the
+current code to this target state. That plan should reference this roadmap
+rather than redefine its architectural decisions or scope.
+
+## Desired End State
+
+Status: Accepted target state; unimplemented.
+
+Weatherreporter uses a pinned released version of
+`gitea.maximumdirect.net/eric/promptkit` as its in-process prompt preparation
+and LLM execution engine. The `scriptorium` executable, subprocess adapter,
+configuration, runtime dependency, and integration documentation have been
+removed.
+
+The migration does not change weatherreporter's fundamental product behavior.
+Weather selection, forecast derivation, report periods, module construction,
+Recent Changes, generated-text interpretation, Markdown templates, durable
+state, inspection, output copies, and distributor notification remain owned by
+weatherreporter.
+
+All report prompts and private response schemas are versioned application
+assets. Operators may configure Promptkit execution profiles without replacing
+the report-owned prompt and schema 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 prompt execution contract.
+Promptkit request, result, validation, error, profile, backend, and provider
+types do not leak into application orchestration, report definitions, domain
+packages, CLI summaries, state contracts, or distributor behavior.
+
+## Goals
+
+Status: Accepted migration scope; unimplemented.
+
+- Remove the runtime dependency on the `scriptorium` executable.
+- Replace shell-free subprocess orchestration with typed in-process Promptkit
+  preparation and execution.
+- Preserve the seven report definitions and their existing prompt IDs.
+- Preserve both direct-Markdown and generated-text-template report workflows.
+- Preserve deterministic module snapshots and structured Recent Changes.
+- Preserve context cancellation, actionable errors, secret redaction, and
+  inspectable failures.
+- Improve durable prompt provenance with prompt, input, profile, model,
+  validation, usage, and timing metadata.
+- Keep content-rich prompt and response diagnostics separate from routine
+  metadata and CLI output.
+- Keep tests offline and deterministic through injected Promptkit model
+  clients and fixtures.
+
+## Non-Goals
+
+Status: Accepted migration scope; unimplemented.
+
+The migration will not:
+
+- 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 to weatherreporter;
+- add automatic provider, validation, or capacity retries;
+- add concurrent report generation to the existing sequential batch workflow;
+- expose Promptkit types as a weatherreporter component contract;
+- keep a production-selectable Scriptorium/Promptkit dual-run mode; or
+- use an unpublished Promptkit commit, committed Go workspace, or committed
+  local module replacement.
+
+## Locked Decisions
+
+Status: Accepted decisions for the unimplemented migration.
+
+### Dependency And Versioning
+
+- The initial integration will pin Promptkit `v0.3.0`.
+- Coordinated local development may temporarily use the sibling Promptkit
+  checkout, but committed module metadata must reference the tagged release.
+- A future Promptkit upgrade requires an explicit review of the public engine,
+  prompt/profile/schema formats, error identities, validation behavior, and
+  outbound provider contract used by weatherreporter.
+
+### Application Boundary
+
+- Promptkit remains an adapter boundary even though it runs in process.
+- A weatherreporter-owned contract will represent preparation, execution,
+  output formats, validation, usage, provenance, and neutral error categories.
+- The Promptkit adapter will map public Promptkit values into that contract at
+  the boundary.
+- App orchestration and test fakes will depend on the weatherreporter contract,
+  not on Promptkit.
+- Existing Scriptorium-specific generation mode names will be replaced with
+  provider-neutral names.
+
+### Prompt And Schema Ownership
+
+- Weatherreporter will embed all report prompt definitions, prompt content,
+  and private response schemas.
+- Prompt assets will remain separate files rather than inline Go strings.
+- The current Scriptorium prompt corpus will be retrieved before the
+  implementation stage that establishes the embedded Promptkit assets.
+- The retrieved corpus will be reviewed and converted to the pinned Promptkit
+  format without changing report intent or prompt IDs.
+- The four existing generated-text prompt fragments and schemas under
+  `internal/reporttemplate` will be reconciled with that corpus rather than
+  duplicated.
+- Direct-Markdown prompt assets for the three-day, weekend, and storm reports
+  will become weatherreporter-owned assets.
+- Weatherreporter needs one centralized embedded prompt/schema source; it does
+  not need Notarius's multi-module asset-flattening registry.
+
+### Profiles, Backends, And Credentials
+
+- Execution profiles remain operator-configurable rather than embedded report
+  policy.
+- Configuration will support at most one external profile source: a profile
+  directory or a single profile file.
+- Prompt definitions may provide their normal default profile, while
+  weatherreporter may support an explicit configured profile selection.
+- Credential values remain in environment variables or file-backed
+  environment secrets. Configuration contains only credential source names.
+- Provider credentials must not appear in logs, errors, CLI output, durable
+  metadata, preparation artifacts, execution artifacts, or debug summaries.
+- Weatherreporter will not expose Promptkit's general backend registry as
+  arbitrary application configuration.
+
+### Engine Lifetime
+
+- One Promptkit engine will be constructed per CLI invocation at the
+  application composition boundary.
+- Single-report generation will use that engine for preparation and execution.
+- Morning and evening batches will share the same engine across every planned
+  report.
+- Per-report orchestration will not construct its own default Promptkit engine.
+- Promptkit backend capacity state and HTTP transport will therefore be shared
+  consistently for the invocation.
+
+### Prompt Input
+
+- Promptkit will continue to receive the curated `data_package` produced by
+  `internal/promptinput`.
+- Weatherreporter will serialize the data package once, atomically persist
+  those exact bytes, and supply the same bytes as a Promptkit inline artifact.
+- The managed data-package path may be supplied as non-secret artifact
+  provenance.
+- Weatherreporter will not delegate unrestricted path loading to Promptkit's
+  default file artifact reader.
+- The same immutable Promptkit request will be used for preparation and
+  execution so the preflight and run inputs cannot diverge.
+
+### Preparation And Execution
+
+- Promptkit `Prepare` replaces the current Scriptorium render preflight.
+- Promptkit `Run` performs both Markdown and structured generated-text
+  execution.
+- Promptkit basic validation will be used where appropriate for direct
+  Markdown output.
+- Promptkit JSON Schema validation provides the provider-facing and first
+  structured-output check for generated-text reports.
+- Weatherreporter's `internal/generatedtext` validation remains the final
+  report-specific domain boundary.
+- Weatherreporter's `internal/reporttemplate` remains responsible for
+  generated-text Markdown rendering.
+- Weatherreporter will atomically persist Promptkit output rather than asking
+  the dependency to write managed report files.
+- The migration will not rely on Promptkit output repair. Promptkit v0.3.0's
+  public engine validates in a single pass even when a prompt declares repair
+  attempts.
+
+## Durable Artifacts And Observability
+
+Status: Accepted design constraints; unimplemented.
+
+Routine durable artifacts should retain useful non-secret provenance without
+persisting full rendered prompts by default.
+
+The preparation record should contain:
+
+- prompt ID and version;
+- prompt definition hash;
+- rendered prompt hash;
+- input hashes;
+- selected profile and backend identity;
+- effective model identity;
+- output contract summary; and
+- preparation timing.
+
+The execution record and run metadata should contain, when available:
+
+- Promptkit run ID;
+- prompt ID, version, and hashes;
+- input hashes;
+- selected profile, backend, and model identity;
+- generated-content hash;
+- token usage;
+- start, end, and duration;
+- validation status and bounded diagnostics; and
+- the path of any separately persisted raw generated output.
+
+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
+will be available only through an explicitly enabled debug mechanism. Debug
+artifacts must be documented as potentially sensitive, must not contain
+credentials, and must have a clear operator-owned retention policy.
+
+## Failure Contract
+
+Status: Accepted design constraints; unimplemented.
+
+Promptkit returns a completed `RunResult` for output-validation failure but no
+partial result for operational preparation or execution errors. Weatherreporter
+will preserve that distinction.
+
+- A preparation failure produces a redacted weatherreporter-owned failure
+  receipt with report, RunID, prompt, stage, timing, and classified error
+  context. It does not fabricate a Promptkit preparation result.
+- 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 failure retains the returned result, raw generated
+  output, validation details, and safe provenance before the report fails.
+- A later weatherreporter generated-text decode, domain-validation, or template
+  failure retains every raw and validated artifact reached before that stage.
+- Context cancellation takes precedence when the caller context is canceled.
+- Promptkit capacity rejection maps to a weatherreporter-owned error category.
+  It is an operational report failure, not invalid model output.
+- Single-report commands return the classified failure with available
+  inspectable paths.
+- Batch runs continue independent later reports under the existing batch
+  failure policy.
+- The migration adds no automatic retries. Any future retry policy belongs to
+  app orchestration, not the Promptkit adapter.
+
+## Compatibility Requirements
+
+Status: Accepted design constraints; unimplemented.
+
+- Report IDs, prompt IDs, report selection, valid periods, artifact grouping,
+  output names, and distributor bundle behavior remain stable.
+- Module snapshot and Recent Changes behavior remains deterministic.
+- Promptkit receives only the existing curated prompt-input boundary.
+- Generated reports continue to use the managed Markdown path as the
+  distributor upload source.
+- RunID lookup and inspection remain available for successful and failed runs.
+- Existing managed state paths remain stable where their meaning is unchanged.
+  Scriptorium-specific artifact names or schemas may change when retaining
+  them would misrepresent the new contract.
+- Any artifact or metadata schema change is 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 Promptkit providers or credentials.
+
+## Verification And Completion Criteria
+
+Status: Proposed completion criteria for the unimplemented migration.
+
+The migration is complete when:
+
+- all seven reports prepare and execute through Promptkit using embedded
+  report-owned assets;
+- direct-Markdown and generated-text-template paths have deterministic offline
+  adapter and app-level coverage;
+- preparation, provider failure, capacity rejection, cancellation, timeout,
+  Promptkit validation failure, generated-text validation failure, template
+  failure, and successful generation preserve their specified artifacts;
+- morning and evening batches construct one shared engine and preserve current
+  collection, planning, ordering, continuation, output, and notification
+  behavior;
+- configuration examples load and contain no Scriptorium fields;
+- CLI summaries and inspection commands expose the new artifact contract
+  without Promptkit dependency types;
+- Scriptorium code, configuration, tests, and runtime documentation have been
+  removed;
+- non-roadmap documentation describes only the implemented Promptkit
+  integration;
+- `go test ./...`, 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 the current Scriptorium behavior is sufficient
+for migration verification. A production-selectable dual-run period is not
+required because model calls are nondeterministic, costly, and difficult to
+compare meaningfully.
+
+## External Prerequisite
+
+Status: Required and unimplemented.
+
+Before implementing the embedded asset stage, the current Scriptorium prompt
+corpus must be made available in this repository. It should include the seven
+prompt definitions, referenced content files, private response schemas,
+relevant default-profile declarations, and any shared prompt fragments needed
+to reproduce current report behavior.
+
+## Open Questions
+
+Status: Open; these require decisions before implementation.
+
+- What exact `promptkit.*` configuration fields should replace the current
+  Scriptorium fields, including the name and precedence of an optional explicit
+  profile override?
+- Should weatherreporter expose Promptkit's conventional `local` backend
+  registration as a narrow configuration feature, or rely initially on
+  built-in and endpoint-only profiles?
+- Should report definitions store an explicit Promptkit prompt version, or
+  should each embedded prompt ID be required to have exactly one version?
+- What CLI or configuration control enables sensitive prompt/response debug
+  artifacts, and where should those artifacts live?
+- What final names and schema versions should replace the
+  Scriptorium-specific preflight and run-result artifacts while balancing
+  semantic clarity with existing state-path compatibility?

+# 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`; `prompts/daily.generated_text.md` |
+| Today | `templates/today.md.tmpl` (`today`) | `today` | `weather.today_generated_text`; `prompts/today.generated_text.md` |
+| Tomorrow | `templates/tomorrow.md.tmpl` (`tomorrow`) | `tomorrow` | `weather.tomorrow_generated_text`; `prompts/tomorrow.generated_text.md` |
+| Hourly | `templates/hourly.md.tmpl` (`hourly`) | `hourly` | `weather.hourly_generated_text`; `prompts/hourly.generated_text.md` |
+
+The matching schema files are under `internal/reporttemplate/schemas/`. The
+generated-text catalog pairs each schema ID with its template ID; keep the
+matching report prompt source 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 Scriptorium. |
+| `.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 Scriptorium 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).

-## `weather_api.base_url is required`
+## A command or configuration is rejected before work starts
 
-Symptom: a generation command fails before fetching weather data.
+Symptom: The command exits before it creates a run, with an unknown-flag,
+missing-argument, invalid date or time bound, invalid timezone, or
+`weather_api.base_url` message.
 
-Likely cause: no Weather API base URL is configured.
+Likely cause: The command does not accept that option for the requested report,
+or required command and configuration values are absent or malformed.
 
-Diagnostic:
+Diagnostic: Compare the command with [`generate` and `run`](cli.md#commands-and-usage)
+and review the configured value named in the error. `generate daily` requires
+`--date`; `generate storm` requires both `--start` and `--end`.
 
-```sh
+Safe fix: Correct only the reported option or configuration value. Use an
-weatherreporter generate daily --config ./config.yml --date 2026-05-29

-config path with `--config`.
 
-Relevant docs: [Configuration reference](config.md).
+## Weather data cannot be collected
 
-## `weather_api.base_url must be an absolute URL`
+Symptom: A generation command fails while fetching weather data, or reports
+`hourly forecast data is missing` or `contains no periods`.
 
-Symptom: config loading fails with a base URL validation error.
+Likely cause: The Weather API is unavailable, its configured endpoint or
+credentials are unsuitable, or the response lacks the hourly forecast required
+by the selected report.
 
-Likely cause: `weather_api.base_url` is missing a scheme or host.
+Diagnostic: Check the service status and the configured base URL, then retry
+the same report. If a run ID was produced, run `weatherreporter inspect sources
+RUN_ID` to see the recorded source result.
 
-Diagnostic: inspect the configured value in the file passed to `--config`.
+Safe fix: Restore access to the configured Weather API or choose a reporting
+period supported by the returned forecast. Do not invent missing hourly values
+in local artifacts.
 
-Safe fix: use an absolute URL such as `https://weather.api.example.com/`.

+collection still completed.
 
-Likely cause: `weather_api.timezone` or `--tz` is not recognized.
+Diagnostic: Run `weatherreporter inspect sources RUN_ID` and identify the
+source and warning recorded for that run.
 
-Diagnostic:
+Safe fix: Correct the affected source configuration or service issue, then
+generate a new report if the missing optional information is needed. Keep the
+existing run for comparison.
 
-```sh
+See also: [Inspecting a run](cli.md#inspection-commands) and [Operations](operations.md).
-weatherreporter generate daily --tz America/Chicago --date 2026-05-29

-Safe fix: use an accepted timezone value, such as an IANA timezone name,
+## Scriptorium cannot be prepared
-`Chicago`, `Stl`, a US timezone abbreviation, or a UTC offset.
 
-Relevant docs: [Configuration reference](config.md).
+Symptom: The report fails with a fragment such as `run scriptorium render`, or
+the Scriptorium executable cannot be started.
 
-## Storm Command Rejects Time Bounds
+Likely cause: The configured executable, profile, prompt, or its local runtime
+environment is unavailable to Weatherreporter.
 
-Symptom: `generate storm` fails with `requires --start`, `requires --end`, or
+Diagnostic: Confirm that the configured executable can be run by the same user
-`requires --end after --start`.
+and inspect `weatherreporter inspect metadata RUN_ID` when a run ID is shown.
 
-Likely cause: the manual event window is missing or invalid.
+Safe fix: Repair the executable path or the Scriptorium configuration and retry
+the report. Do not edit generated artifacts to bypass preparation.
 
-Diagnostic:
+See also: [Configuration](config.md) and [Operations](operations.md).
 
-```sh
+## Scriptorium preflight fails

+a `scriptorium render exited with code` fragment.
 
-Relevant docs: [CLI reference](cli.md).
+Likely cause: Scriptorium rejected the render request, prompt, profile, or data
+package before it could run the report.
 
-## Weather API Fetch Fails
+Diagnostic: Inspect the run metadata and the saved preflight artifact path it
+references. Compare the reported Scriptorium diagnostic with its configuration.
 
-Symptom: generation fails with `fetch /...`, an HTTP status, or request context.
+Safe fix: Correct the reported Scriptorium input or configuration, then create
+a new run. Preserve the failed preflight artifact for support or comparison.
 
-Likely cause: the configured Weather API endpoint is unreachable, returned a

-Diagnostic:
+## Scriptorium report execution fails
 
-```sh
+Symptom: Preparation succeeded, but generation stops with a

-Relevant docs: [Configuration reference](config.md).
+Diagnostic: Inspect the run metadata and preflight artifact, then review the
+exit diagnostic from the command. This distinguishes a run failure from a
+preflight failure.
 
-## Hourly Forecast Is Missing
+Safe fix: Correct the Scriptorium issue identified by that diagnostic and run
+the report again; leave the failed run artifacts in place.
 
-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.
+## Generated text fails validation
 
-Diagnostic: check the Weather API response for `/forecast/hourly`.
+Symptom: A generated-text report fails after Scriptorium returns text, with a
+message about generated text or required report content.
 
-Safe fix: restore hourly forecast data at the Weather API. Missing-source
+Likely cause: Returned text does not meet the report's validation rules.
-policy cannot make hourly optional.
 
-Relevant docs: [Configuration reference](config.md), [Operations guide](operations.md).
+Diagnostic: Use `weatherreporter inspect metadata RUN_ID` to find the saved raw
+generated-text artifact, and inspect it alongside the reported validation
+message.
 
-## Source Warnings Appear
+Safe fix: Correct the upstream prompt or generation configuration that caused
+the invalid output, then create a new run. Do not hand-edit saved raw text and
+present it as a validated report.
 
-Symptom: generation succeeds, but metadata or `inspect sources` shows source

-Relevant docs: [Configuration reference](config.md), [Operations guide](operations.md).
+Safe fix: Correct the template or its supported inputs in source control, test
+the change, and create a new report. Do not alter the saved context merely to
+make one historical run render.
 
-## `scriptorium` Is Not Found Or Cannot Start
+See also: [Operations](operations.md).
 
-Symptom: generation fails with `run scriptorium render` or `run scriptorium`
+## A report fails after artifacts are saved
-and an executable or OS error.
 
-Likely cause: the configured Scriptorium binary is unavailable or not
+Symptom: A generation command reports an error after showing a run ID, such as
-executable.

+destination for `--out`, or a later report-delivery failure occurred after
+earlier steps succeeded.
 
-Safe fix: install Scriptorium, update `scriptorium.binary`, or fix executable
+Diagnostic: Run `weatherreporter inspect metadata RUN_ID` and check the exact
+path and operation named in the error. For an `--out` failure, verify only the
+specified destination directory and filename.
+
+Safe fix: Repair access to that exact path or disable the optional delivery
+step only when appropriate, then generate a new report. Keep the existing
+managed artifacts untouched.
+
+See also: [Operations](operations.md) and [Distributor integration](integrations/distributor/pkg-upload.md).
+
+## A batch has partial report failures
+
+Symptom: `run morning` or `run evening` returns nonzero and reports both
+succeeded and failed report items.
+
+Likely cause: A report-level collection, generation, rendering, or local
+output failure affected one or more planned reports; the remaining reports
+continue independently.
+
+Diagnostic: Read the per-report status lines, then inspect the run ID for each
+failed item with `weatherreporter inspect metadata RUN_ID`.
+
+Safe fix: Correct the specific failure and rerun the batch or affected report.
+Do not delete successful reports simply because another item failed.
+
+See also: [Batch commands](cli.md#commands-and-usage) and [Operations](operations.md).
+
+## A batch upload is skipped
+
+Symptom: The batch result says Distributor notification was skipped because
+one or more reports failed.
+
+Likely cause: Batch notification intentionally runs only after every planned
+report succeeds.
+
+Diagnostic: Review the failed report items and their metadata; a skipped batch
+notification is expected while any item is failed.
+
+Safe fix: Resolve the report failures and rerun the batch. Do not upload a
+partial bundle by manually reusing batch artifacts.
+
+See also: [Batch commands](cli.md#commands-and-usage) and [Operations](operations.md).
+
+## Distributor notification fails
+
+Symptom: A completed report or otherwise successful batch reports a Distributor
+error, including a rejected upload, source or idempotency conflict, or service
+unavailability.
+
+Likely cause: Distributor rejected the request identity or bundle, required
+credentials are unavailable, or the remote service cannot be reached.
+
+Diagnostic: Inspect the report metadata or batch result for the notification
+artifact and the error fragment. Verify the configured Distributor endpoint and
+request identity without exposing credentials.
+
+Safe fix: Resolve the reported remote conflict, configuration, or availability
+issue and create a new report or rerun the batch. Do not modify recorded bundle
+or idempotency artifacts to force an upload.
+
+See also: [Configuration](config.md), [Distributor integration](integrations/distributor/pkg-upload.md), and [Operations](operations.md).
+
+## Secrets cannot be loaded
+
+Symptom: Startup reports `read secrets directory`, `secret file`, or a token
+environment-variable error before the affected service can be used.
+
+Likely cause: The configured secrets directory cannot be read, contains a
+non-regular file, or does not supply the environment variable required by an
+enabled integration.
+
+Diagnostic: Check the configured secrets directory path, ownership, and that
+each intended secret is a regular file. Confirm the variable name from
+configuration only; never print or paste its value.
+
+Safe fix: Correct permissions, file type, or the missing secret file, then
+retry. Keep secret values out of commands, logs, tickets, and artifacts.
+
+See also: [Configuration](config.md) and [Operations](operations.md).
+
+## A run ID or saved state cannot be found
+
+Symptom: An inspection command reports that metadata for a run ID was not
+found, or a report cannot use a prior snapshot.
+
+Likely cause: The run ID is wrong, the configured workspace is different from
+the one that created the run, or no compatible prior snapshot exists.
+
+Diagnostic: Use `weatherreporter inspect reports` to list available reports in
+the current workspace, then copy the run ID from that output. Confirm the
+workspace configuration before retrying a prior-snapshot operation.
+
+Safe fix: Use an existing run ID and its original workspace, or generate a new
+compatible report when no prior snapshot is available. Do not fabricate state
+files or run IDs.
+
+See also: [Inspecting a run](cli.md#inspection-commands) and [Operations](operations.md).
+
+## Workspace paths cannot be read or written
+
+Symptom: Startup or report persistence reports a workspace-path, permission,
+or "must be relative to workspace root" error.
+
+Likely cause: A configured artifact directory escapes the workspace, or the
+current user lacks access to the specific workspace location.
+
+Diagnostic: Check the named configuration path against the configured workspace
+root and inspect ownership and permissions of that exact directory.
+
+Safe fix: Set the path to a location within the workspace or repair access to
+the named directory, then rerun. Do not remove the workspace or broadly relax
 permissions.

-
-## 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.
