 # weatherreporter
 
-`weatherreporter` is a Go application for preparing human-facing weather
-reports from normalized forecast data. It builds JSON module snapshots, passes
-YAML prompt data packages to `scriptorium`, and keeps inspectable artifacts
-under a local workspace. It can also upload successfully generated managed
-Markdown reports to a configured `distributor` HTTP upload endpoint.
+Weatherreporter is a Go CLI that turns normalized weather data into
+human-facing Markdown reports.
+
+It produces a Markdown report at an operator-owned destination and can upload
+the completed output through Distributor.
 
 ## Quickstart
 
 ```sh
-weatherreporter generate daily --date 2026-05-29 --out ./daily.md
+weatherreporter generate today
 ```
 
+Configure a Weather API endpoint first; see the
+[configuration reference](docs/config.md). The report is written to
+`today.md` in the current directory when `output.directory` is not configured.
+Set that configuration value for an ordinary publication directory, or use
+`--out` for one command. See the [CLI reference](docs/cli.md) and [operations
+guide](docs/operations.md) for command and operating details.

+# 0001: Make Weatherreporter Execution Stateless
+
+Status: Accepted
+
+Date: 2026-08-01
+
+## Context
+
+Weather reports are ephemeral products. Forecasts and current conditions change
+continuously, so the useful response to an old, failed, or superseded report is
+normally a new generation rather than replaying or inspecting a prior run.
+
+The existing run-addressed workspace retains module snapshots, prompt inputs,
+execution receipts, generated text, rendered reports, metadata, and
+notification receipts. That provenance store accumulates operational history
+whose recovery and compatibility obligations are disproportionate to the value
+of an ephemeral weather report. It also exists solely to support local Recent
+Changes comparison for a rarely used report section.
+
+The temporary roadmap that defined the feature scope and implementation plan
+has been retired under the repository's documentation lifecycle. The
+[architecture policy](../policy/architecture.md) defines the resulting system
+invariants; this decision records their durable rationale.
+
+## Decision
+
+Weatherreporter will operate as a stateless transformation pipeline:
+
+```text
+Weather API input
+  -> deterministic facts and modules
+  -> Promptkit data package and generated text
+  -> repository-owned Markdown rendering
+  -> operator-owned report output
+  -> optional Distributor upload
+```
+
+Ordinary invocations will retain intermediate values only for the active
+process and will publish one operator-owned Markdown output atomically. A
+failed or canceled generation must not truncate or partially replace an
+existing selected output. Single-report Distributor notification follows
+successful publication; batch notification follows successful publication of
+every planned report.
+
+Weatherreporter will remove local Recent Changes comparison instead of
+retaining application state to support it. It will remove run-addressed
+workspace artifacts, historical inspection, and backward-compatible workspace
+decoding. RunIDs may remain active correlation and Distributor idempotency
+values, but will not identify retained application history.
+
+Explicit `--llm-debug-dir` capture remains the sole diagnostic-file exception.
+The operator selects and manages that secure location; ordinary execution does
+not create an implicit debug location or a general logging store, and debug
+capture must continue to exclude credentials.
+
+Any future forecast comparison must use a structured product supplied by the
+Weather API rather than local Weatherreporter history. The proposed
+[Upstream Forecast Change Product](../roadmap/future.md#upstream-forecast-change-product)
+defines the required upstream direction. A future integration must not add a
+local snapshot fallback.
+
+## Alternatives Considered
+
+### Retain The Bounded Current-State Design
+
+Retaining a managed workspace with current metadata, receipts, and snapshots
+would preserve inspection and local comparison, but keeps an application-owned
+history subsystem, artifact compatibility burden, and recovery surface that do
+not match the report lifecycle.
+
+### Time-Based Retention
+
+Expiring workspace material after a fixed period reduces accumulation but still
+requires retention policy, cleanup behavior, failure handling, and historical
+format support. It does not remove the mismatch between retained provenance and
+ephemeral report products.
+
+### Bounded Run History
+
+Keeping only a fixed number of prior runs limits storage volume but still makes
+Weatherreporter responsible for run selection, comparison, inspection, and
+state migration. It also creates arbitrary history gaps without establishing an
+authoritative forecast baseline.
+
+## Consequences
+
+The CLI, configuration, prompt-input, workspace, and inspection contracts will
+change together. Legacy workspace material will not be migrated, decoded, or
+automatically deleted; operators remain responsible for any desired cleanup.
+
+Current action results will carry active identity, selected profile, safe
+effective model information, output location, notification result, and safe
+errors instead of historical artifact paths. Tests will protect atomic output,
+batch and notification ordering, explicit secure debug capture, and the
+absence of ordinary application-managed state.
+
+This decision deliberately leaves the Weather API responsible for any future
+forecast-history comparison. It avoids a cache, archive, retention engine,
+manifest, resume mechanism, or replacement inspection surface in
+Weatherreporter.

 # Weatherreporter CLI
 
-`weatherreporter` generates Markdown weather reports, runs scheduled report
-batches, and inspects stored artifacts.
+`weatherreporter` generates Markdown weather reports and runs report batches.
+It has no command for inspecting prior runs or application-owned state.
 
 ## Shortest Useful Command
 
 ```sh
-weatherreporter generate daily --date 2026-05-29 --out ./daily.md
+weatherreporter generate today
 ```
 
-This loads configuration, fetches weather data, writes managed workspace
-artifacts, runs `scriptorium render` as a preflight check, runs
-`scriptorium run`, and writes an extra Markdown copy to `./daily.md`. If
-distributor notification is enabled in configuration, the command also uploads
-the managed Markdown report after final metadata is saved.
+The command uses the configured Weather API and atomically writes `today.md`.
+With no configured output directory, it writes in the current directory. See
+the [configuration reference](config.md) to supply the required Weather API
+endpoint and choose an ordinary output directory.

-`generate` commands write a JSON module snapshot, YAML data package, preflight
-artifact, managed Markdown report, and metadata under the configured workspace.
-`--out` writes an extra Markdown copy for the operator; distributor
-notification uses the managed report path, not the extra copy. `generate storm`
-requires explicit event-window bounds with `--start` and `--end`.
+`weatherreporter --version` prints the version embedded in the executable.
+Tagged release binaries report their semantic version tag; ordinary local
+builds report `development`.
 
-`run morning` generates Daily Today and the 3-Day Outlook, plus Weekend Outlook
-except on Sunday. `run evening` generates the Tomorrow Planning Brief. Batch
-runs continue independent reports after a failure, print a JSON summary to
-stdout, write compact status lines to stderr, and return nonzero when any report
-failed. `--out-dir` writes extra Markdown copies for the operator; distributor
-notification uses each managed report path, not the extra copies. When
-notification is enabled, batch summaries and status lines include notification
-status, accepted distributor run ID, or notification error fields for each
-attempted report.
+| Command | Contract |
+| --- | --- |
+| `generate daily` | Requires `--date YYYY-MM-DD`; the date is interpreted in the effective report timezone. Its default filename is `daily-YYYY-MM-DD.md`. |
+| `generate today` | Accepts an optional `--date YYYY-MM-DD`; without it, the current local date in the effective report timezone is used. Its default filename is `today.md`. |
+| `generate tomorrow` | Uses the next local civil day and writes `tomorrow.md` by default. |
+| `generate hourly` | Covers the next six hours in the effective report timezone and writes `hourly.md` by default. It does not accept `--date`, `--hours`, or `--duration`. |
+| `run morning` and `run evening` | Run their defined report batches beneath the configured output directory, or the current directory when none is configured. `--out-dir` selects another directory. `--out` is not accepted. |
 
-`inspect` commands read existing workspace artifacts and emit JSON to stdout.
-They do not fetch weather data or invoke `scriptorium`.
+`generate` accepts the four report command names shown above. `run` accepts
+only `morning` and `evening`. Batch membership and notification ordering are
+described in the [operations guide](operations.md).
 
-## Flags
+## Output, Errors, And Quiet Mode
 
-- `-h`, `--help`: show help.
-- `--config PATH`: load configuration from `PATH` instead of `/usr/local/etc/weatherreporter/config.yml`.
-- `--units VALUE`: override configured Weather API units for `generate` and `run`.
-- `--tz NAME`: override configured Weather API timezone for `generate` and `run`.
-- `--out PATH`: write an extra Markdown report copy for `generate` commands.
-- `--out-dir PATH`: write extra Markdown report copies for `run morning` and `run evening`.
-- `--date YYYY-MM-DD`: optional date for `generate daily`; defaults to the current local date in the configured timezone.
-- `--start TIME`: required start time for `generate storm`.
-- `--end TIME`: required end time for `generate storm`.
-- `--limit N`: maximum records for `inspect reports`; defaults to `20`, and `0` means no limit.
+For `generate`, the report's default filename is placed beneath
+`output.directory` when configured, otherwise the current directory. `--out
+PATH` selects one complete output file instead. A relative path is resolved
+from the current directory; an absolute path is used as given. For a batch,
+the configured directory has the same role and `--out-dir PATH` selects its
+output directory instead. Successful summaries always report the resulting
+absolute `outputPath` values. See the [configuration reference](config.md) for
+the field's validation and path rules.
 
-Storm times accept `YYYY-MM-DDTHH:MM` in the configured timezone or RFC3339
-timestamps with explicit offsets.
+Outputs are written atomically. A generation, rendering, write, or cancellation
+failure before publication leaves an existing destination unchanged. A
+notification failure occurs after publication, so the newly written output
+remains available.
 
-Distributor notification is configured only through `notify.distributor`; there
-are no distributor-specific CLI 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.
 
-## Common Workflows
+`--quiet` is supported by action commands only. It suppresses action summaries
+and routine batch status output; it does not suppress command errors.
+
+### Generate Summary
+
+A generate summary identifies the command, report, run, generation time, valid
+period, prompt version, timezone, and status. Successful output has an absolute
+`outputPath`:
+
+```json
+{
+  "command": "generate",
+  "reportId": "today",
+  "promptId": "weather.today_generated_text",
+  "promptVersion": "2.0.0",
+  "runId": "20260529T120000.000000000Z_today",
+  "status": "succeeded",
+  "timezone": "America/Chicago",
+  "outputPath": "/srv/weather/today.md"
+}
+```
+
+When available, the summary also includes the effective `profileId`,
+`backendId`, `modelName`, `sourceWarnings`, `validationStatus`, requested
+`llmDebugPath`, and compact Distributor `notification` result. It does not
+include historical or transient artifact paths such as metadata, prompt input,
+raw generated text, render context, or notification receipts.
+
+### Run Summary And Stderr
+
+A run summary contains `command`, `batch`, `status`, `startedAt`, `finishedAt`,
+`total`, `succeeded`, `failed`, and a `reports` array. Each report item includes
+its identity, status, effective profile and model details when available,
+source warnings, validation status, and absolute `outputPath` after publication.
+The top-level summary may also contain a batch `notification` object and
+`error`. Batch status is `failed` if any report or the batch notification fails.
+The `total`, `succeeded`, and `failed` counters describe report items only, so
+a failed batch notification can leave `failed` at `0` while the top-level
+notification and action status are `failed`.
+
+Without `--quiet`, batch status lines use this form:
+
+```text
+report=today status=succeeded output="/srv/weather/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 the report to this complete file destination instead of the configured or current-directory default. |
+| `--llm-debug-dir PATH` | every `generate` and `run` command | Write requested sensitive prompt diagnostics under this absolute path. |
+| `--out-dir PATH` | `run morning`, `run evening` | Write batch reports beneath this directory instead of the configured or current-directory default. |
+| `--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. |
+
+Distributor notification is configured through `notify.distributor`; there are
+no Distributor-specific CLI flags. See the [configuration reference](config.md).
+

-weatherreporter inspect sources 20260529T100000.000000000Z_daily_today
-```
-
-`inspect reports` lists recent generated runs with artifact paths and source

-returns the persisted ordered module snapshot for a run. `inspect prior`
-returns the prior comparable snapshot metadata selected from stored metadata, or
-`null` when none exists. `inspect sources` shows source provenance and source
-warnings without dumping full weather payloads.

 ## Field Reference
 
 ### `weather_api`
 
-- `base_url`: absolute base URL for the Weather API. Required for generation and fetch workflows.
-- `timeout`: HTTP timeout duration. Default: `10s`.
-- `precision`: numeric precision query value. Default: `1`.
-- `units`: Weather API units query value. Default: `us`.
-- `timezone`: report timezone and Weather API timezone query value where supported. Default: `America/Chicago`.
-- `format`: Weather API response format. Must be `json`. Default: `json`.
+| Field | Default | Rules |
+| --- | --- | --- |
+| `base_url` | empty | Absolute Weather API URL. Required for collection and generation. |
+| `timeout` | `10s` | Must be greater than zero. |
+| `precision` | `0` | Must be zero or greater. Sent as the Weather API precision query value. |
+| `units` | `us` | Required Weather API units query value; `--units` overrides it for one command. |
+| `timezone` | `America/Chicago` | Required report and Weather API timezone; `--tz` overrides it for one command. |
+| `format` | `json` | Required and must be `json`. |
 
 Timezone values may be IANA names, configured aliases such as `Chicago` and
 `Stl`, US timezone abbreviations, or UTC offsets such as `-5` and `+09:30`.
 
 ### `location`
 
-`location` is descriptive prompt context included in module metadata and
-Scriptorium data packages. It does not select a Weather API endpoint or enable
-multiple configured forecast locations.
+`location` supplies descriptive prompt context; it does not choose a Weather
+API endpoint or configure multiple forecast locations.
 
-- `id`: short local identifier. Default: `home`.
-- `name`: human-readable location name. Default: `Brentwood`.
-- `region`: broader forecast area context. Default: `St. Louis Metro`.
+| Field | Default |
+| --- | --- |
+| `id` | `home` |
+| `name` | `Brentwood` |
+| `region` | `St. Louis Metro` |
 
-The prompt-facing location object also includes `timezone`, derived from the
-effective `weather_api.timezone` after CLI overrides such as `--tz`.
+The prompt-facing location timezone is derived from the effective
+`weather_api.timezone` after command-line overrides.
 
 ### `secrets`
 
-- `directory`: optional directory of file-backed environment secrets. Default:
-  empty, which disables secret loading.
+`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.
 
-When configured, each regular file directly under `secrets.directory` is loaded
-after config file parsing and CLI overrides. The file basename must be a valid
-environment variable name matching `[A-Za-z_][A-Za-z0-9_]*`; the file contents
-become the environment variable value and overwrite any existing value. One
-trailing LF or CRLF is stripped. Subdirectories, symlinks, invalid filenames,
-missing directories, and unreadable files fail config loading.
+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`
+### `output`
 
-`notify.distributor` controls distributor notification after successful report
-generation. It is disabled by default and does not add CLI flags. When enabled,
-weatherreporter uploads one distributor bundle per generated report after
-`scriptorium run` succeeds and final metadata is saved.
+`output.directory` selects the ordinary operator-owned publication directory

-- `enabled`: whether distributor notification config is active. Default:
-  `false`.
-- `endpoint`: absolute distributor endpoint URL. Required when enabled.
-  Default: `https://distributor.example.com`.
-- `token_env`: environment variable name that will contain the distributor
-  upload token. Required when enabled. Default: `DISTRIBUTOR_UPLOAD_TOKEN`.
-- `timeout`: distributor operation timeout. Must be greater than zero when
-  enabled. Default: `30s`.
-- `failure_policy`: must be `error` when enabled. Default: `error`.
-- `pipeline_id_template`: template for the distributor pipeline ID. Required
-  when enabled. Default: empty.
-- `bundle_id_template`: template for distributor bundle IDs. Default:
-  `weatherreporter.{location_id}.{report_id}`.
-- `idempotency_key_template`: template for distributor idempotency keys.
-  Default: `{bundle_id}.{run_id}`.
-- `report_path_templates`: ordered list of templates for Markdown report paths
-  inside the distributor bundle. Each rendered path maps to the same managed
-  Markdown report source. Default:
-  ```yaml
-  - "{valid_start_date}/{artifact_group}/{valid_start_date}-{artifact_group}-{run_id}.md"
-  ```
+| Field | Default | Rules |
+| --- | --- | --- |
+| `directory` | empty | An omitted or empty value uses the invocation working directory. A nonempty value must contain at least one non-whitespace character. |
 
-Supported template variables are `location_id`, `report_id`, `run_id`,
+The configured value is preserved while configuration loads: it is not cleaned,
+made absolute, inspected, created, or expanded through environment variables or
+a home-directory shortcut. At execution, an absolute directory is used as
+given; a relative directory resolves from the invocation working directory, not
+from the configuration file's location. A missing directory is created when a
+report is successfully published. An existing non-directory or an uninspectable
+path fails output preflight before prompt inspection, weather collection, or
+publication.
+
+For one `generate` command, `--out` is a complete file destination and takes
+precedence over `output.directory`. For `run`, `--out-dir` takes precedence.
+Those explicit flags do not inspect or rebase beneath the configured directory.
+See the [CLI reference](cli.md) for command selection and the [operations
+guide](operations.md) for publication and failure handling.
+
+### `notify.distributor`
+
+Distributor notification is disabled by default. Its fields are:
+
+| Field | Default | Rules when notification is enabled |
+| --- | --- | --- |
+| `enabled` | `false` | Activates Distributor notification validation. |
+| `endpoint` | `https://distributor.example.com` | Must be an absolute URL. |
+| `token_env` | `DISTRIBUTOR_UPLOAD_TOKEN` | Must name a valid environment variable. |
+| `timeout` | `30s` | Must be greater than zero. |
+| `failure_policy` | `error` | Must be `error`. |
+| `pipeline_id_template` | empty | Required single-report pipeline ID template. |
+| `bundle_id_template` | `weatherreporter.{location_id}.{report_id}` | Required single-report bundle ID template. |
+| `idempotency_key_template` | `{bundle_id}.{run_id}` | Required single-report idempotency-key template. |
+| `batch.enabled` | `true` | Activates batch notification validation when Distributor notification is enabled. |
+| `batch.pipeline_id_template` | `weatherreporter` | Required when batch notification is enabled. |
+| `batch.bundle_id_template` | `weatherreporter.{location_id}.{batch}` | Required when batch notification is enabled. |
+| `batch.idempotency_key_template` | `{bundle_id}.{batch_run_id}` | Required when batch notification is enabled. |
+
+The upload token is read from the environment variable named by `token_env`.
+Use `secrets.directory` when a file-backed secret is appropriate.
+
+Single-report bundle templates accept `location_id`, `report_id`, `run_id`,
 `artifact_group`, `batch_output_name`, `valid_start_date`, `valid_end_date`,
-`valid_start_time`, `valid_end_time`, `valid_start_stamp`, and
-`valid_end_stamp`. Date values use `YYYY-MM-DD`, time values use `HHMM`, and
-stamp values use `YYYY-MM-DDTHHMM` in the effective report timezone.
-`pipeline_id_template` and `idempotency_key_template` may also use `bundle_id`.
+`valid_start_time`, `valid_end_time`, `valid_start_stamp`, `valid_end_stamp`,
+Pipeline and idempotency-key templates may also use `bundle_id`. Dates use
+`YYYY-MM-DD`; times use `HHMM`; and stamps use `YYYY-MM-DDTHHMM` in the
+effective report timezone.
 
-The rendered pipeline ID selects the configured distributor `http_upload`
-workflow. The rendered bundle ID is the stable logical source identity for the
-report stream. The rendered idempotency key is the per-run retry identity.
+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.
 
-Rendered report paths must be unique relative paths with `/` separators. They
-must not contain backslashes, empty path segments, `.`, `..`, `manifest.json`,
-or `.distributor.json`.
+`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:
 
-The upload token is read from the environment variable named by `token_env`
-after config loading and `secrets.directory` processing. Config files should
-name the variable only; they should not contain the token value.
+| Report | Paths |
+| --- | --- |
+| `hourly` | `hourly/index.md` |
+| `daily` | `daily/{valid_start_date}/{run_id}.md`, `daily/{valid_start_date}/index.md` |
+| `today` | `daily/{valid_start_date}/{run_id}.md`, `daily/{valid_start_date}/index.md`, `today/index.md` |
+| `tomorrow` | `daily/{valid_start_date}/{run_id}.md`, `daily/{valid_start_date}/index.md`, `tomorrow/index.md` |
+
+See the [operations guide](operations.md) for notification timing, uploaded
+output selection, and failure handling.
 
 ### `missing_source`
 
-- `default`: missing-source behavior for optional sources. One of `error`, `warn`, or `none`. Default: `warn`.
-- `sources`: optional map of source-specific overrides, using the same policy values.
+`missing_source.default` defaults to `warn` and accepts `error`, `warn`, or
+`none`. `missing_source.sources` optionally overrides that policy by source.
+Hourly forecast data is required for generated reports. Supported optional
+source keys are `observations`, `current`, `narrative`, `alerts`, `discussion`,
+`weather_story`, and `spc_convective_outlooks`.
 
-Hourly forecast data is required for generated reports. Optional sources use
-the missing-source policy.
+### `promptkit`
 
-### `scriptorium`
+Promptkit configuration selects the executor and prompt/profile checks for
+every `generate` and `run` command. A top-level `scriptorium:` configuration
+key is rejected with a migration error; it is not translated or ignored.
 
-- `binary`: `scriptorium` executable name or path. Default: `scriptorium`.
-- `config_path`: optional Scriptorium config path passed to the adapter.
-- `profile`: optional Scriptorium profile passed to the adapter.
-- `timeout`: subprocess timeout. Default: `2m`.
-- `extra_args`: optional additional arguments passed to Scriptorium commands.
+Prompt debug capture has no YAML setting. Use `--llm-debug-dir PATH` on an
+individual `generate` or `run` command when explicitly needed.
 
-### `workspace`
+| Field | Default | Rules |
+| --- | --- | --- |
+| `profile` | empty | Optional global profile selection for every report in one command. When empty, each exact prompt version selects its declared default. |
+| `profile_file` | empty | Optional external Promptkit profile file. It cannot be combined with `profile_dir`. A same-ID profile completely replaces Weatherreporter's embedded definition. |
+| `profile_dir` | empty | Optional external Promptkit profile directory. It cannot be combined with `profile_file`. A same-ID profile completely replaces Weatherreporter's embedded definition. |
+| `timeout` | `2m` | Must be greater than zero. |
+| `local.endpoint` | empty | Optional absolute URL for the conventional local backend. A blank endpoint leaves it unregistered. |
+| `local.concurrency_limit` | `1` | Maximum local backend concurrency. `0` is unlimited; negative values are invalid. |
 
-- `root`: workspace root for managed artifacts. Default: `workspace`.
-- `snapshots_dir`: module snapshot and metadata directory under `workspace.root`. Default: `snapshots`.
-- `reports_dir`: managed Markdown report directory under `workspace.root`. Default: `reports`.
-- `data_packages_dir`: prompt input package directory under `workspace.root`. Default: `data-packages`.
-- `preflight_dir`: Scriptorium render output directory under `workspace.root`. Default: `preflight`.
-- `notifications_dir`: distributor notification debug artifact directory under `workspace.root`. Default: `notifications`.
+`profile` selects an ID; `profile_file` and `profile_dir` supply definitions.
+They are separate decisions. An explicit `profile` applies to every selected
+report. Otherwise Hourly selects `weather-light`, while Daily, Today, and
+Tomorrow select `weather-balanced` through their exact `2.0.0` prompt
+definitions.
 
-Workspace subdirectories must be relative paths that stay inside
-`workspace.root`.
+Promptkit resolves a selected profile definition from a test or embedding
+consumer's explicit in-memory profile, then the configured `profile_file` or
+`profile_dir`, then Weatherreporter's embedded catalog, and finally Promptkit's
+built-in catalog. Sources provide complete definitions; fields are never
+merged. A matching malformed external profile fails rather than using the
+embedded definition. The [Promptkit integration guide](integrations/promptkit.md)
+owns the catalog and precedence details.
+
+To replace the default Hourly definition with a local OpenAI-compatible
+endpoint, set `profile_file` to a copy of
+[weather-light-local-profile.yml](../examples/weather-light-local-profile.yml).
+The example has no credential and should be edited for the local endpoint and
+model before use. An alternative profile may use `backend: local`; in that
+case `promptkit.local.endpoint` supplies the conventional local backend
+endpoint.
 
 ### `dayparts`
 
-`dayparts` is a list of named local-time windows used by forecast derivation.
-Each entry has:
-
-- `name`
-- `start`
-- `end`
-
-`start` and `end` use `HH:MM`. The default entries are overnight, morning,
-midday, afternoon, and evening.
-
-### `recent_change`
-
-- `temperature_degrees`: temperature change threshold. Default: `5`.
-- `precip_probability_points`: precipitation probability threshold. Default: `20`.
-- `wind_gust_miles_per_hour`: wind gust change threshold. Default: `10`.
-- `precip_timing_shift_minutes`: precipitation timing shift threshold. Default: `120`.
-
-Recent Changes are added to prompt input when a prior comparable module
-snapshot exists and a threshold is crossed.
+`dayparts` is a non-empty list of named local-time windows used in forecast
+derivation. Every item needs `name`, `start`, and `end`; start and end use
+`HH:MM`. Defaults are `overnight` (`00:00`–`06:00`), `morning`
+(`06:00`–`10:00`), `midday` (`10:00`–`15:00`), `afternoon`
+(`15:00`–`17:00`), and `evening` (`17:00`–`24:00`).
 
 ### `reports`
 
-`reports` optionally overrides the ordered deterministic modules declared by
-report definitions. Omit a report entry to use its default module order.
+`reports` optionally overrides a report's ordered deterministic modules and
+Distributor path templates. Omit a report entry to retain its defaults.
 
-Supported report keys are `daily`, `tomorrow`, `three_day`, `weekend`, and
-`storm`. Canonical report IDs such as `daily_today` and `daily_tomorrow` are
-also accepted.
+Supported report keys are `daily`, `today`, `tomorrow`, and `hourly`; hyphens
+and underscores are equivalent.
 
-Each report entry supports:
+Each report entry can contain:
 
-- `deterministic_modules`: ordered module list. Entries may be string module
-  IDs or objects with `id` and optional `options`.
+- `deterministic_modules`: an ordered list of module IDs, or objects with `id`
+  and optional `options`.
+- `distributor.path_templates`: an optional, non-empty ordered list of
+  Distributor paths for that report.
 
-Example:
-
-```yaml
-reports:
-  daily:
-    deterministic_modules:
-      - metadata
-      - current_conditions
-      - narrative_forecast
-      - id: area_forecast_discussion
-        options:
-          sections:
-            - short_term
-      - hourly_forecast
-```
-
-Unknown reports, unknown modules, duplicate modules, incompatible report/module
-combinations, duplicate stanza names, and invalid options fail config loading.
-`area_forecast_discussion.options.sections` may contain `product`,
-`key_messages`, `short_term`, and `long_term`. Empty or omitted `sections`
-includes all available AFD sections.
-
-The module registry accepts all module IDs documented in
-[Module Contract Internals](internal/module.md). Unknown or unimplemented
-module IDs fail validation instead of being skipped.
-
-## Secrets
-
-Configuration files should not contain raw secrets. Use `secrets.directory` to
-load secret values from files into environment variables for integrations that
-read credentials from the environment. Secret file names become environment
-variable names, and secret file contents become values. For distributor
-notification, this allows a file such as
-`<secrets.directory>/DISTRIBUTOR_UPLOAD_TOKEN` to supply the token referenced by
-`notify.distributor.token_env`.
-
-## Maintained Examples
-
-- [examples/minimal-config.yml](../examples/minimal-config.yml): smallest
-  useful config for generation and fetching.
-- [examples/config.yml](../examples/config.yml): production-oriented config
-  covering maintained fields.
-
-Both example files are loaded by the config test suite.
+Unknown reports and modules, duplicate modules, incompatible report-module
+combinations, duplicate stanza names, invalid path templates, and invalid
+module options fail configuration loading. The accepted module IDs and module
+option contracts are documented in the [module contract internals](internal/module.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, executes Promptkit for
+single-report generated text, renders Markdown reports, and can upload completed
+operator-owned outputs 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. |

+| 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. |

-# Upstream Producer Integration
+# Distributor HTTP Upload Contract
 
-Audience: developers and LLM coding agents adding `distributor` support to an upstream Go producer application.
+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).
 
-This document is the copyable implementation guide for submitting producer outputs to a `distributor` pipeline whose source backend is `http_upload`.
+## Upload Admission
 
-## Required Inputs
+Weatherreporter uses an absolute HTTP(S) endpoint as a base URL. The client
+posts a gzip-compressed source bundle to:
 
-The upstream application needs these values from deployment or operator configuration:
-
-- distributor endpoint: the HTTP server base URL, such as `https://distributor.example.com`;
-- upload token: bearer token that authenticates the producer;
-- pipeline id: configured `http_upload` pipeline that should process this upload;
-- generated files: regular local files to include in the source bundle;
-- bundle id: stable identifier for the logical report stream or artifact;
-- idempotency key: unique key for one producer run, reused only when retrying that same run.
-
-Do not put destination routing, public URLs, transform settings, or credentials in the source manifest. Those belong in the `distributor` pipeline configuration.
-
-The token, pipeline id, bundle id, and idempotency key have different jobs. The token authenticates the producer. The pipeline id selects the configured distributor workflow, including destinations and publishing policy. The bundle id tells `distributor` whether a new upload is a newer version of the same source; keep it stable across runs that should replace the same managed destination artifact. The idempotency key tells `distributor` whether an upload request is a retry; change it for each distinct producer run so new content is enqueued.
-
-## Recommended Workflow
-
-Use `gitea.maximumdirect.net/eric/distributor/pkg/upload`.
-
-For most producers, use `UploadFiles`. It accepts producer-generated files, builds a temporary valid source bundle with `pkg/bundle`, uploads a gzip-compressed tar archive, and removes temporary files when the call returns.
-
-Use `UploadBundle` only when the producer already assembled a complete bundle directory containing `manifest.json`.
-
-Add the dependency from the upstream application:
-
-```sh
-go get gitea.maximumdirect.net/eric/distributor
+```text
+POST /v1/pipelines/<pipeline_id>/upload
+Authorization: Bearer <token>
+Content-Type: application/gzip
+Idempotency-Key: <key>
 ```
 
-## Minimal Go Example
+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.
 
-```go
-package reports
+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).
 
-import (
-	"context"
-	"errors"
-	"fmt"
-	"os"
-	"time"
+## Idempotency
 
-	"gitea.maximumdirect.net/eric/distributor/pkg/bundle"
-	"gitea.maximumdirect.net/eric/distributor/pkg/upload"
-)
+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.
 
-func SubmitReport(reportPath, summaryPath string) error {
-	endpoint := os.Getenv("DISTRIBUTOR_UPLOAD_ENDPOINT")
-	token := os.Getenv("DISTRIBUTOR_UPLOAD_TOKEN")
-	if endpoint == "" || token == "" {
-		return fmt.Errorf("distributor endpoint and token are required")
-	}
+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.

-## Producer Responsibilities
+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.
 
-- Use a stable bundle id for the logical producer output that should replace the same destination artifact, such as `weather.hourly.brentwood`.
-- Set `PipelineID` to the configured upload pipeline that should process the bundle.
-- Do not include per-run timestamps, random values, or job ids in the bundle id unless each run should be treated as a different source.
-- Use an idempotency key that changes for every distinct producer run, such as `<bundle-id>.<run-id>`.
-- Reuse the same idempotency key only when retrying the exact same producer run with the same source manifest.
-- Map each generated file to a clean slash-separated bundle path, such as `report.md` or `assets/chart.png`.
-- Include only regular files. Symlinks, directories as files, devices, FIFOs, and sockets are rejected.
-- Keep file contents stable after upload inputs are selected. Bundle digests are calculated from file bytes.
-- Treat upload success as admission only. `UploadFiles` and `UploadBundle` return after the server accepts and validates the upload, not after all destinations publish.
+Run and idempotency records are in-memory. Completed records expire according
+to Distributor's `server.http.retention`, and a Distributor restart removes

-Valid bundle paths are relative slash paths. They must not be empty, absolute, contain backslashes, contain `.` or `..` path segments, contain empty path segments, or use reserved basenames `manifest.json` or `.distributor.json`.
+## Compatibility Reference
 
-## Idempotency And Status
-
-`pkg/upload` sends `Idempotency-Key` on every upload. If the caller omits one, the package generates a random key for that call and reuses it for in-process retries. That is enough for transient network retry within one process, but it does not give cross-process retry identity.
-
-For producer jobs that may retry after process restart, supply a key derived from the producer run, such as `<bundle-id>.<run-id>`. Reusing the same key with the same token, pipeline id, and normalized source manifest returns the original accepted run. Reusing the same key with different source content in that scope returns a conflict. Reusing one key across multiple distinct report generations prevents those generations from being treated as new uploads.
-
-`Status` polls `/runs/<run-id>` while the distributor server retains the in-memory status record. Status values are `accepted`, `queued`, `running`, `succeeded`, and `failed`. Completed records expire according to the server's `server.http.retention` setting, and server restart clears status and idempotency records.
-
-Optional status check:
-
-```go
-status, err := client.Status(ctx, result.RunID)
-if err != nil {
-	return err
-}
-if status.Status == "failed" {
-	return fmt.Errorf("distributor run failed: %s", status.Error)
-}

-# `pkg/bundle`
+# Distributor Source Bundle Mapping
 
-Audience: upstream Go producer developers and LLM coding agents using `distributor` source bundle helpers.
+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.
 
-Import path:
+## File Mappings
 
-```go
-import "gitea.maximumdirect.net/eric/distributor/pkg/bundle"
-```
+Every mapping pairs an operator-owned Markdown output with one bundle-relative
+path. A single-report notification maps its published output to each rendered
+path configured for that report. A batch notification combines mappings for
+every included published output and rejects duplicate bundle paths.
 
-`pkg/bundle` builds, writes, parses, and validates local source bundles. Use it directly when a producer writes bundles for `distributor` to discover, or when a producer wants to assemble and validate a bundle before using another transport.
+The report source is the output selected for that command; the application does
+not scan local directories. It renders notification paths after publication;
+see the [operations guide](../../operations.md) and the
+[Distributor adapter](../../internal/distributor-adapter.md) for the boundary.
 
-The canonical source bundle file-format contract is [Source Bundle Contract](../integrations/source-bundle.md).
+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.
 
-## Preferred Complete-Bundle Workflow
+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.
 
-Use `WriteBundle` when producer-generated files live outside the final bundle root.
+## Compatibility Reference
 
-```go
-manifest, err := bundle.WriteBundle(bundle.WriteBundleOptions{
-	Root: "/var/spool/distributor/weather/hourly-2026-06-07T15",
-	ID:   "weather.hourly.brentwood",
-	Files: []bundle.BundleFile{
-		{SourcePath: "/tmp/weather/report.md", Path: "report.md"},
-		{SourcePath: "/tmp/weather/summary.txt", Path: "summary.txt"},
-	},
-})
-if err != nil {
-	return err
-}
-_ = manifest
-```
-
-`WriteBundle` copies each source file into a staged bundle root, writes `manifest.json`, validates the staged bundle, and promotes it into place. Set `Overwrite: true` only when the producer intentionally replaces an existing bundle root.
-
-## Existing Bundle Root Workflow
-
-Use `BuildManifest` and `WriteManifest` when files are already staged under the final bundle root.
-
-```go
-root := "/var/spool/distributor/weather/hourly-2026-06-07T15"
-manifest, err := bundle.BuildManifest(bundle.BuildOptions{
-	Root:  root,
-	ID:    "weather.hourly.brentwood",
-	Files: []string{"report.md", "summary.txt"},
-})
-if err != nil {
-	return err
-}
-if err := bundle.WriteManifest(root, manifest, bundle.WriteManifestOptions{}); err != nil {
-	return err
-}
-if err := bundle.ValidateBundle(root, manifest); err != nil {
-	return err
-}
-```
-
-Use `Scan: true` instead of `Files` only when every valid regular file under the root should be included. Scan mode includes dotfiles, skips reserved metadata files, rejects symlinks, and sorts paths lexically.
-
-## Paths And Ordering
-
-Bundle paths are slash-separated paths relative to the bundle root.
-
-Invalid paths include:
-
-- empty paths;
-- absolute paths;
-- paths containing backslashes;
-- `.` or `..` path segments;
-- empty path segments;
-- any basename of `manifest.json` or `.distributor.json`.
-
-Explicit file lists preserve caller order. File order is part of the bundle digest, so producers should choose it deliberately and keep it stable.
-
-The manifest `ID` is the logical source identity used by `distributor` destination comparison. Keep it stable for runs that should replace the same managed destination artifact. If every run uses a different manifest `ID`, `distributor` treats those runs as different sources and may report a destination conflict instead of replacing older output.
-
-## Validation And Digest Helpers
-
-Use `ValidateBundle` before handing an existing local bundle to another process. It verifies manifest semantics, file existence, regular-file type, file size, per-file SHA-256 digests, and bundle digest.
-
-Useful helpers:
-
-- `LoadManifest`: read `manifest.json` from a bundle root.
-- `ParseManifest` and `MarshalManifest`: parse or write manifest bytes.
-- `ValidateManifest`: validate manifest-only semantics.
-- `FileDigest`, `BundleDigest`, and `ValidateDigest`: digest helpers for diagnostics and tests.
-
-## Boundaries
-
-`pkg/bundle` does not upload bundles, publish destinations, transform Markdown, select pipelines, configure credentials, or write destination state. Those concerns belong to `pkg/upload` or the `distributor` application.
+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.

-# `pkg/upload`
+# Distributor Upload Client Contract
 
-Audience: upstream Go producer developers and LLM coding agents submitting bundles to `distributor serve`.
+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.
 
-Import path:
+## Client And Upload
 
-```go
-import "gitea.maximumdirect.net/eric/distributor/pkg/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.
 
-`pkg/upload` is the producer-facing HTTP upload client. It builds on `pkg/bundle`, packages valid source bundles as gzip-compressed tar archives, sends bearer authentication, routes uploads to a configured pipeline, includes idempotency keys, and exposes a status polling helper.
+For each notification, Weatherreporter calls `UploadFiles` with:
 
-`UploadFiles` examples also use:
+- the rendered pipeline ID;
+- the rendered bundle ID as the source manifest ID;
+- the report or batch generation time as `Created`;
+- the published-output-to-bundle-path mappings described in the
+  [bundle mapping contract](pkg-bundle.md); and
+- a rendered idempotency key.
 
-```go
-import "gitea.maximumdirect.net/eric/distributor/pkg/bundle"
-```
+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.
 
-The canonical HTTP wire contract is [HTTP Upload API Contract](../integrations/http-upload.md).
+## Retry, Conflict, And Status
 
-## Client Construction
+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.
 
-```go
-client, err := upload.NewClient(upload.ClientOptions{
-	Endpoint: "https://distributor.example.com",
-	Token:    token,
-})
-if err != nil {
-	return err
-}
-```
+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.
 
-`Endpoint` is the distributor server base URL. The client derives `/v1/pipelines/<pipeline-id>/upload` and `/runs/<run-id>`. `Token` is required and is sent as `Authorization: Bearer <token>`. Token values are redacted from client errors.
+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, and redaction are
+internal behavior documented in the
+[Distributor adapter](../../internal/distributor-adapter.md) and
+[application orchestration](../../internal/app-orchestration.md).
 
-`HTTPClient` and `Retry` are optional. Defaults use a 30 second HTTP timeout and safe retry settings.
+## Compatibility Reference
 
-## Upload Producer Files
-
-Use `UploadFiles` when the producer has generated output files but has not assembled a bundle directory.
-
-```go
-result, err := client.UploadFiles(ctx, upload.UploadFilesOptions{
-	PipelineID:     "weather-hourly",
-	ID:             "weather.hourly.brentwood",
-	IdempotencyKey: "weather.hourly.brentwood.20260607T150000Z",
-	Files: []bundle.BundleFile{
-		{SourcePath: "/tmp/weather/report.md", Path: "report.md"},
-		{SourcePath: "/tmp/weather/summary.txt", Path: "summary.txt"},
-	},
-})
-if err != nil {
-	return err
-}
-_ = result.RunID
-```
-
-`PipelineID` is required and selects the configured distributor workflow for this upload. `ID` is the source manifest id and identifies the logical artifact inside that workflow. `UploadFiles` creates a temporary bundle, writes and validates a manifest, uploads the archive, and removes temporary files when the call returns. It does not write into producer source directories.
-
-## Upload An Existing Bundle
-
-Use `UploadBundle` when the producer already has a complete local bundle root containing `manifest.json`.
-
-```go
-result, err := client.UploadBundle(ctx, upload.UploadBundleOptions{
-	PipelineID:     "weather-hourly",
-	Root:           "/var/spool/weather/hourly-2026-06-07T15",
-	IdempotencyKey: "weather.hourly.brentwood.20260607T150000Z",
-})
-if err != nil {
-	return err
-}
-_ = result.RunID
-```
-
-`PipelineID` is required for existing bundles too. `UploadBundle` validates the local bundle by default and uploads only `manifest.json` plus manifest-listed files. Unlisted files are not uploaded.
-
-## Result And Status
-
-Upload success means the server returned `202 Accepted` after staging and validating the upload. It does not mean all configured destinations have published.
-
-Poll status while the server retains the in-memory run record:
-
-```go
-status, err := client.Status(ctx, result.RunID)
-if err != nil {
-	return err
-}
-if status.Status == "failed" {
-	return fmt.Errorf("distributor run failed: %s", status.Error)
-}
-```
-
-Status values are `accepted`, `queued`, `running`, `succeeded`, and `failed`. Completed records expire according to `server.http.retention`; server restart clears run status and idempotency records.
-
-## Idempotency And Retry
-
-Every upload request includes `Idempotency-Key`.
-
-If `IdempotencyKey` is omitted, the client generates a random 128-bit lowercase hexadecimal key for that upload operation and reuses it for retries within the same call. For cross-process retry safety, producers should pass a key derived from the producer run, such as `<bundle-id>.<run-id>`.
-
-Do not reuse the same idempotency key for multiple distinct report generations. Reuse it only when retrying the exact same run with the same token, pipeline id, and source manifest. A repeated key with the same manifest in that scope returns the original accepted run instead of enqueueing another run; a repeated key with different content returns an idempotency conflict.
-
-The client retries only safe cases:
-
-- `503 Service Unavailable`;
-- temporary network errors;
-- ambiguous mid-upload failures.
-
-It does not retry after `202 Accepted` and does not retry `400`, `401`, `403`, `404`, `409`, `413`, or `415`.
-
-Detect conflicting key reuse with `errors.As`:
-
-```go
-var conflict *upload.IdempotencyConflictError
-if errors.As(err, &conflict) {
-	return fmt.Errorf("idempotency key was reused for different bundle content: %w", err)
-}
-```
-
-## Boundaries
-
-`pkg/upload` does not configure server pipelines, choose destinations, wait for publication completion automatically, persist client queues, provide durable idempotency across server restarts, or expose destination state. It submits complete source bundles to the configured HTTP upload API.
+The upstream package workflow is documented in
+`docs/consumers/pkg-upload.md` in the Distributor repository. Weatherreporter
+uses only the client construction, `UploadFiles`, retry/conflict behavior, and
+`Status` operations described here.

+# Promptkit Integration
+
+Weatherreporter uses Promptkit for all generated-text reports. The four logical prompts are `weather.daily_generated_text`, `weather.today_generated_text`, `weather.tomorrow_generated_text`, and `weather.hourly_generated_text`, each at version `2.0.0`. Their prompt assets, generated-text JSON Schemas, and Weatherreporter profile catalog are embedded by `internal/promptassets`.
+
+## Logical Profile Catalog
+
+Prompt definitions select a stable Weatherreporter profile ID. The embedded definitions currently use Promptkit's `openrouter` backend:
+
+| Profile ID | Model | Reasoning effort | Timeout | Service tier | Default reports |
+| --- | --- | --- | --- | --- | --- |
+| `weather-light` | `deepseek/deepseek-v4-flash` | Provider default | 180 seconds | `flex` | Hourly |
+| `weather-balanced` | `~google/gemini-flash-latest` | `high` | 240 seconds | `flex` | Daily, Today, Tomorrow |
+| `weather-deep` | `~anthropic/claude-sonnet-latest` | `high` | 240 seconds | `flex` | None |
+
+The `~` prefix is part of each OpenRouter rolling-alias model ID. The embedded profiles intentionally omit endpoints, credentials, temperature, `top_p`, and output-token limits.
+
+## Selection And Active Execution
+
+Before weather collection, Weatherreporter validates the exact prompt version, output contract, and selected profile. A nonblank `promptkit.profile` selects one profile ID for every report in the command; otherwise the prompt's declared default selects it. Promptkit resolves the selected definition in this order:
+
+1. explicit in-memory profiles used by an embedding consumer or test;
+2. the configured `profile_file` or `profile_dir`;
+3. Weatherreporter's embedded fallback profiles; and
+4. Promptkit's built-in catalog.
+
+A source falls through only when the selected ID is absent. Each source supplies a complete definition, so profile fields are not merged. A malformed matching operator definition is an error and does not fall back.
+
+Profiles that require a direct API key are unsupported; a profile that reports `APIKeyEnv` requires a nonblank value in that environment variable. Active results retain the selected logical profile ID and resolved backend and model. Ordinary errors, summaries, logs, and outputs exclude endpoints, credentials, rendered messages, schemas, request bodies, response bodies, and complete parameter maps.
+
+Promptkit receives the YAML data package as an inline input and returns structured JSON that Weatherreporter validates before rendering its own Markdown template. Safe active provenance remains in memory. Content-rich diagnostics are opt-in through `--llm-debug-dir`; see [operations](../operations.md) for retention and permissions.
+
+The generated-text schemas require `summary`, `forecast_discussion`, and `precipitation_timing`, and reject additional properties. Prompts return an empty string for `precipitation_timing` when the deterministic package contains no precipitation windows.
+
+Prompt/profile configuration and the maintained local override example are owned by the [configuration reference](../config.md). Adapter construction and mapping are documented in the [Promptkit adapter internals](../internal/promptkit-adapter.md).

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

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

+| Narrative forecast | `/forecast/narrative` | `format`, `units`, `precision`, `tz` | Optional |

-- `precision`: from `weather_api.precision` on observations, current
-  conditions, hourly forecast, and narrative forecast requests

-## Required And Optional Sources
+### Alerts, Discussion, And Weather Story
 
-Hourly forecast is required:
+`/alerts/active` uses the `asOf` timestamp and keeps each item in `alerts` as
+an alert payload. Weatherreporter does not require a separate alert-item schema
+at this integration boundary.
 
-- `data: null` for `/forecast/hourly` fails the fetch.
-- an hourly forecast with no `periods` fails the fetch.
-- malformed hourly data fails the fetch.
+`/discussion` uses `officeId`, `officeName`, `product`, `issuedAt`,
+`updatedAt`, `keyMessages`, and the `shortTerm` and `longTerm` sections. Each
+section uses `qualifier`, `text`, and `issuedAt`.
 
-Other fetched sources are optional and follow `missing_source.default` or a
-source-specific `missing_source.sources` policy:
+`/weatherstories/latest` uses `officeId`, `startTime`, `endTime`, `updatedAt`,
+`title`, `description`, `altText`, `priority`, `order`, and `downloadUrl`.
 
-- `observations` for `/observations`
-- `current` for `/conditions/current`
-- `narrative` for `/forecast/narrative`
-- `alerts` for `/alerts/active`
-- `discussion` for `/discussion`
-- `weather_story` for `/weatherstories/latest`
+### SPC Convective Outlooks
 
-Policy behavior:
+`/outlooks/convective` uses run-level `locationId`, `locationName`, `asOf`,
+`issuedAt`, `updatedAt`, `product`, `outlooks`, and `discussions`.
 
-- `error`: fail the fetch for that source
-- `warn`: omit the source data, add a warning, and continue
-- `none`: omit the source data and continue without a warning
+Each outlook uses `id`, `provider`, `product`, `day`, `outlookType`, `label`,
+`labelText`, `forecaster`, `severityRank`, `validFrom`, `validTo`, `issuedAt`,
+`expiresAt`, `sourceUrl`, `imageUrl`, `containsLocation`, and GeoJSON
+`geometry`. Each discussion uses `day`, `headline`, `summary`, `discussion`,
+and `updatedAt`.
 
-For `/alerts/active`, an HTTP error or missing `data` field still fails or
-follows the relevant error path, but explicit `data: null` is not a
-missing-source condition.
+## Timeouts, Retries, And Failures
 
-## Source Identity
+The configured Weather API timeout applies to each warmup and source HTTP
+attempt. Weatherreporter retries transient transport and response-read failures
+and these response statuses: `408`, `429`, `500`, `502`, `503`, and `504`.
+It does not retry other HTTP statuses, malformed envelopes, missing data, or
+payload decoding failures. A canceled context also stops an in-progress retry
+delay.
 
-For source payloads accepted into the bundle, including the explicit `null`
-alerts payload, the adapter records:
+The adapter reads at most 10 MiB from one response body. A non-2xx response,
+request construction failure, read failure, or decode failure includes endpoint
+context in its error.
 
-- source name
-- endpoint path
-- query parameters sent
-- fetch time
-- source issue and update timestamps when present in the payload
-- SHA-256 hash of the compact raw `data` JSON
-
-Warnings are recorded both on the affected source and on the bundle-level
-warnings list.
-
-## Compatibility Assumptions
-
-The adapter expects payload fields compatible with the internal forecast bundle
-types in `internal/forecast/bundle.go`, including:
-
-- observation timestamps and observation values
-- current condition values
-- forecast run metadata and `periods`
-- active alert run data
-- discussion metadata, key messages, and short/long-term section text
-- latest weather story title, description, timing, priority, order, alt text,
-  and download URL
-
-The adapter intentionally keeps upstream transport and envelope details inside
-`internal/adapters/weatherapi`; downstream packages consume the normalized
-bundle.
+Retry counts and delays are adapter behavior rather than Weather API request
+parameters. Do not depend on a particular attempt count when implementing the
+service.

-# App Orchestration Internals
+# Application Orchestration Internals
 
-This document describes the workflow coordinator in `internal/app`.
+`internal/app` owns stateless report generation, batch execution, atomic output publication, and notification coordination after `internal/cli` has parsed arguments and loaded configuration. The user contract is owned by the [CLI reference](../cli.md) and [operations guide](../operations.md).
 
-## Purpose
+## Single-Report Flow
 
-`internal/app` coordinates the top-level use cases after CLI parsing and config
-loading are complete. It resolves report definitions, fetches weather data,
-builds collected and derived facts, builds module snapshots and prompt-input
-artifacts, invokes Scriptorium through the adapter boundary, optionally
-notifies distributor through an app-owned notifier boundary, persists managed
-state, runs batches, and reads existing artifacts for inspection.
+`GenerateDetailed` resolves the requested report and output destination before initializing an optional explicit debug writer. An explicit output file wins; otherwise the configured output directory is used, falling back to the captured working directory. It validates the exact Promptkit prompt and selected profile before collecting weather data. The resolved profile, backend, and model are carried in the active result.
 
-## Inputs And Outputs
+The workflow builds facts, a module snapshot, briefing metadata, and the YAML prompt package in memory. It executes Promptkit, validates the returned generated text, builds a render context, and renders Markdown. `fileutil` atomically writes the completed Markdown to the selected output path. Only after that write succeeds does single-report notification run.
 
-Inputs:
+Failures return an active partial result with safe identity, profile, warning, validation, debug, and output information when available. After rendering and immediately before publication, the workflow checks for cancellation or deadline expiry. Any failure before publication leaves an existing destination unchanged. A notification failure retains the newly published output.
 
-- `GenerateRequest` for one report command
-- `BatchRequest` for morning or evening batch commands
-- `FetchBundleRequest` for explicit bundle fetch and save workflows
-- `ReportRequest` for single-report generation
-- resolved report definitions from `internal/report`
-- weather data bundles from `internal/adapters/weatherapi`
-- prior snapshots loaded from `internal/state`
-- optional renderer, notifier, and state-store fakes for tests
+## Batches
 
-Outputs:
+`RunBatchDetailed` selects an explicit output directory first, otherwise the configured directory and then the captured working directory. It does this before creating at most one explicit debug writer or validating prompt and profile candidates for the selected batch. It collects once, calculates the data-dependent plan, then validates and retains the final output path for every planned report before invoking the same generation core sequentially.
 
-- generated report results with JSON module snapshot, YAML data package,
-  preflight, report, metadata, prior snapshot, Recent Changes, Scriptorium
-  result details, and notification result when attempted
-- batch summaries with per-report status, artifact paths, error text, and
-  notification outcome when attempted
-- saved Weather API bundle JSON for fetch workflows
-- inspection JSON values for reports, metadata, module snapshots, data
-  packages, prior snapshots, and source provenance
+Each item has an independent result. A failed item does not stop later items; successful items retain their published output paths. Per-report notification is suppressed during a batch. Batch notification runs only after every planned report has published successfully. It is skipped when any item failed. Batch result counters count report items only; a batch notification failure is represented by the top-level notification result and still produces a failed batch outcome.
 
-## Boundaries
+## Boundaries And Verification
 
-`internal/app` owns workflow order and request composition. It does not parse
-CLI flags, load YAML files directly, implement HTTP transport, own fact
-derivation algorithms, define report periods, compare rendered Markdown, or
-construct Scriptorium argv.
+The package does not parse flags, load YAML, implement transport, construct provider SDKs, or define report-period policy. Prompt, profile, weather, and Distributor implementations remain behind project-owned contracts.
 
-Report selection and report identity policy come from `internal/report`.
-Collected and derived fact contracts come from `internal/facts`.
-Weather API transport stays in `internal/adapters/weatherapi`. Scriptorium
-subprocess behavior stays in `internal/adapters/scriptorium`. Distributor
-upload behavior stays in `internal/adapters/distributor`. Filesystem layout and
-persisted metadata stay in `internal/state`.
+Focused checks:
 
-## Config Fields Used
-
-- `weather_api.*` for Weather API client construction and module metadata
-- `scriptorium.*` for renderer construction
-- `workspace.*` for filesystem state
-- `dayparts` for daily and outlook summarization
-- `recent_change.*` for structured Recent Changes thresholds
-- `notify.distributor.*` for optional notification after report generation
-
-Output copy flags are command request fields. They are not configuration
-defaults.
-
-## Generation Workflow
-
-Single-report generation follows this order:
-
-1. Resolve the command report to a `report.Resolved` value.
-2. Create or use a filesystem store.
-3. Locate any prior compatible snapshot through `internal/state`.
-4. Fetch a Weather API bundle.
-5. Build collected and derived facts once.
-6. Execute configured modules and save the module snapshot.
-7. Compute Recent Changes from structured prior and current module snapshots.
-8. Build and save the YAML Scriptorium `data_package`.
-9. Run Scriptorium render preflight.
-10. Save preflight JSON when a render result is available.
-11. Save metadata for inspection.
-12. Run Scriptorium report generation to the managed report path.
-13. Copy the managed report to the requested `--out` path when provided.
-14. Save metadata with the managed report path.
-15. If distributor notification is enabled, notify using the managed report
-    path as the source file.
-16. Save a distributor notification debug artifact and update metadata with its
-    path.
-
-If render preflight returns both a result and an error, preflight JSON and
-metadata are persisted before the error is returned. If Scriptorium report
-generation returns an error after writing output, the managed report and
-metadata remain inspectable. Notification is not attempted after Weather API,
-module snapshot, prompt input, render, Scriptorium run, or metadata-save
-failures.
-When notification is attempted, the debug artifact records request identity,
-including rendered pipeline ID, bundle paths, accepted upload fields,
-distributor status fields, raw status report JSON when available, and redacted
-failure context.
-`--out` copies are never used as notification source files.
-
-## Batch Workflow
-
-`run morning` resolves Daily Today, 3-Day Outlook, and Weekend Outlook except
-on Sunday. `run evening` resolves Daily Tomorrow. Batch output copy names come
-from report definitions. Batch generation continues independent reports after a
-failure, records each result, writes compact status lines to stderr, emits a
-JSON summary to stdout, and returns an aggregate error when any report failed.
-When notification is enabled, each successfully generated report is notified
-independently. Notification failure marks that report failed, records
-notification fields in the batch result, and does not stop later reports.
-`--out-dir` copies are never used as notification source files.
-
-## Inspection Workflow
-
-Inspection workflows load existing filesystem state only. They do not fetch
-weather data or invoke Scriptorium. Run-specific inspect commands share the same
-store and metadata lookup path, then load the requested artifact or derived
-inspection view.
-
-## Failure Behavior
-
-- Resolve errors stop the requested workflow before fetching weather data.
-- Weather API and module execution errors stop that report before Scriptorium
-  runs.
-- Prompt input validation fails before render preflight.
-- Render and run errors preserve Scriptorium stderr and exit-code context.
-- Notification errors are wrapped with report ID, RunID, and managed report path
-  context and are recorded separately in batch results.
-- Metadata and artifact path errors include filesystem context.
-- Batch failures are recorded per report and surfaced through an aggregate
-  batch error.
-
-## Tests
-
-Inspect:
-
-- `internal/app/app_test.go`
-- `internal/cli/root_test.go`
-- `internal/state/filesystem_test.go`
-
-## Invariants
-
-- Report behavior is resolved through `internal/report`.
-- Generated reports use the same app request and result types regardless of
-  report ID.
-- Render preflight precedes Scriptorium report generation.
-- Recent Changes are computed from structured module snapshots.
-- Metadata links artifacts produced for a run.
-- Distributor notification maps the managed Markdown report path to configured
-  bundle paths; extra output copies are not upload sources.

 # Module Builder Internals
 
-This document describes module builder behavior in `internal/briefing`.
+`internal/briefing` builds typed module outputs from resolved report context,
+collected facts, and derived facts. It owns the module registry, including
+module support, fact requirements, option types, missing-data policy, builders,
+and prompt-export hooks. It does not collect data, derive periods, write a
+snapshot, construct YAML, invoke Promptkit, or render a report.
 
-## Purpose
+## Registry and construction
 
-`internal/briefing` turns report metadata, collected weather data, and derived
-forecast facts into prompt-facing module outputs. The package also owns the
-module registry used to validate report composition and config overrides.
+Every `ModuleDefinition` declares an ID, stanza name, default option value,
+required collected and derived facts, supported report IDs, missing-data
+behavior, duplicate policy, builder, and optional prompt exporter.
 
-Module outputs are structured prompt inputs. They are not rendered report prose
-and they are not persisted by this package.
+`BuildModule` first verifies the requested module, report compatibility, and
+option shape. It then applies the declared missing-data behavior:
 
-## Inputs And Outputs
+- `omit` returns no output for unavailable optional facts;
+- `error` returns the missing fact requirements; and
+- `empty` allows the builder to emit an explicit checked-empty value.
 
-Inputs:
+Unsupported `warn` behavior, missing builders, duplicate registry IDs or
+stanza names, output ID or stanza mismatches, and exporter failures all return
+errors with module context. A successful builder gets a pass-through prompt
+value unless its definition supplies an exporter.
 
-- resolved report definition, generation time, timezone, and valid period
-- collected facts built from `weatherdata.Bundle`
-- derived daily, daypart, precipitation, alert, and storm-window facts where
-  required
-- configured units, timezone, and descriptive location context
-- typed module options from report defaults or config overrides
+## Built value families
 
-Outputs:
+Source-oriented builders shape report metadata, current conditions, narrative
+and hourly forecasts, alert digest, SPC outlooks and discussion, area forecast
+discussion, and weather story. Derived builders shape daily and daypart
+summaries, precipitation timing, outdoor windows, and the report-specific
+Daily, Today, and Tomorrow planning values.
 
-- `ModuleDefinition` values with module ID, stanza name, option type,
-  supported reports, fact requirements, missing-data behavior, and builder
-- `module.Output` values for source-oriented stanzas:
-  `metadata`, `current_conditions`, `narrative_forecast`, `hourly_forecast`,
-  `alert_digest`, `area_forecast_discussion`, and `weather_story`
-- `module.Output` values for derived stanzas:
-  `derived_daily_summary`, `derived_daypart_summaries`, `precip_timing`,
-  `outdoor_windows`, and `tomorrow_planning`
+The module registry preserves rich values for templates and snapshots while
+curating prompt exports where needed. In particular, source warnings are a
+metadata summary, checked-empty alerts and SPC outlooks remain distinct from
+missing sources, and prompt-safe SPC values omit geometry and other
+template-only or source details. The complete module composition is in
+[module internals](module.md); fact derivation is in [fact contracts](facts.md).
 
-Every registered composition entry has a builder. Unknown or unimplemented
-module IDs fail validation instead of being skipped.
+`area_forecast_discussion` accepts an optional typed section filter. Planning
+modules are report-specific: `daily_planning` supports Daily,
+`today_planning` supports Today, and `tomorrow_planning` supports Tomorrow.
 
-Prompt-facing module values use local, human-readable date and time labels
-where the LLM is expected to reason about report content. Canonical timestamps
-remain in report metadata, source provenance, and integration artifacts.
+## Missing data and boundaries
 
-## Boundaries
+Optional current conditions, narrative products, discussions, and weather
+stories may be omitted. Required derived modules fail when their declared facts
+are unavailable. Empty alert and outlook runs can still produce checked-empty
+modules. SPC discussion is omitted unless a retained categorical outlook meets
+the package's severity criterion and matching discussion text exists.
 
-- This package selects and shapes already-collected weather facts for prompts.
-- It validates module composition against report compatibility and option
-  types.
-- It does not fetch weather data, compare prior snapshots, write module
-  snapshots, build YAML data packages, invoke Scriptorium, or write workflow
-  metadata.
+Effective units, timezone, and location context arrive in `ModuleContext` from
+configuration and resolved report metadata. Field defaults are owned by
+[configuration](../config.md), and prompt-package layout is owned by
+[prompt input](prompt-input.md).
 
-## Config Fields Used
+## Verification and invariants
 
-The app layer passes effective units, timezone, and location context into the
-module context. `internal/facts` consumes daypart configuration before module
-builders run. Configured `location` values are prompt context only; Weather API
-`sourceLocationId` and `sourceLocation` remain source provenance.
+Focused tests cover source and derived values, registry validation, option
+handling, prompt exporters, support rules, and missing-data behavior:
 
-`area_forecast_discussion` uses optional `sections` configuration to include a
-subset of discussion fields.
+```sh
+go test ./internal/briefing
+```
 
-## External Adapters Used
-
-None directly.
-
-## State Or Manifest Behavior
-
-None. `internal/app` collects module outputs into a `module.Snapshot`, and
-`internal/state` persists that snapshot.
-
-## Skip And Resume Behavior
-
-None. Builders either emit a module output, omit optional unavailable data, or
-return an error for invalid required inputs.
-
-## Failure Behavior
-
-- Required derived modules return errors when their dependent facts are not
-  available.
-- Module registry construction rejects duplicate module IDs and duplicate
-  stanza names.
-- Composition validation rejects unknown modules, duplicate modules,
-  incompatible report/module combinations, duplicate stanza names, and invalid
-  option shapes.
-- Source-oriented module builders omit missing optional current conditions,
-  forecast discussion, and weather story stanzas.
-- Alert digest output distinguishes checked empty alert data from missing alert
-  source data.
-
-## Tests

-Inspect:
-
-- `internal/briefing/base_modules_test.go`
-- `internal/briefing/derived_modules_test.go`
-- `internal/briefing/modules_test.go`

-
-## Invariants
-
-- Module outputs contain structured weather facts and source context.
-- Common metadata includes RunID, report ID, prompt ID, valid period, source
-  provenance, source hashes, source warnings, and configured prompt location.
-- Prompt input packaging and Scriptorium execution remain outside this package.
+Builders emit structured facts, never report prose. The app collects their
+outputs into an in-memory module snapshot for prompt input and rendering.

-# Changes Internals
-
-This document describes structured Recent Changes comparison.

-
-`internal/changes` compares current and prior module snapshots and emits
-compact change records for prompt input data packages.

-## Inputs And Outputs
-
-Inputs:

-
-Outputs:
-
-- ordered `changes.Change` items with type, message, previous value, and current

-
-- This package compares structured module snapshot data only.
-- It does not read filesystem state, find prior snapshots, render Markdown,

-
-## State Or Manifest Behavior
-
-None directly. The app loads prior module snapshots through `internal/state`

-
-## Skip And Resume Behavior
-
-No resume behavior. When the app has no prior comparable snapshot, it sends an
-empty Recent Changes list without calling a comparison function.
-
-## Failure Behavior
-
-- Daily comparison requires `derived_daily_summary` and

+`internal/cli` parses terminal arguments, loads configuration, constructs app requests, and translates app results to bounded JSON summaries. The public contract belongs in the [CLI reference](../cli.md).
+
+The root `--version` flag reports the build version supplied by `internal/buildinfo`. Tagged release builds replace its development default at link time.
+
+For each `generate` or `run` action, `Runner` constructs one project-owned Promptkit executor after configuration loads. It captures an absolute working directory, resolves only a relative explicit output override against it, and passes the working directory, loaded configuration, resolved override, and any `--llm-debug-dir` request to the app. The raw configured fallback remains in the configuration for app-owned destination selection. `run` uses the same explicit-resolution rule for `--out-dir`.

+The CLI dispatches only generation and batch actions. It has no persisted-run or inspection dispatch. Summaries include report identity, status, output path, effective profile/backend/model, source warnings, validation, requested debug path, and notification result when available. They intentionally exclude prompt input, raw generated text, render context, endpoints, credentials, and full Distributor payloads.

+`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,

+errors and fetch failures as bundle-collection errors. It does not retry,
+persist, select reports, derive facts, build modules, invoke Promptkit, 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.

 # Distributor Adapter Internals
 
-This document describes the distributor upload adapter in
-`internal/adapters/distributor`.
+`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).
 
-## Purpose
+## Client construction
 
-The adapter submits generated weatherreporter Markdown reports to a configured
-distributor HTTP upload endpoint. It isolates distributor package types,
-token-env lookup, upload client construction, source-bundle file mapping,
-timeout handling, status polling, and upload error wrapping from app
-orchestration.
+`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.
 
-## Inputs And Outputs
+The upstream client is an implementation dependency, not a source of
+application configuration: retry ownership, pipeline selection, path
+templates, and report rendering are defined by
+[configuration](../config.md) and [application orchestration](app-orchestration.md).
 
-Inputs:
+## Upload translation
 
-- distributor endpoint URL
-- token environment variable name
-- upload timeout
-- pipeline ID
-- bundle ID
-- idempotency key
-- source Markdown report path and bundle-relative path mappings
-- bundle created timestamp
-- context for cancellation
+Before calling the dependency, `Upload` validates the endpoint and token
+configuration plus the local pipeline ID, bundle ID, idempotency key, and every
+file's source and bundle paths. It maps the request as follows:
 
-Outputs:
+| 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 |
 
-- accepted distributor run ID
-- accepted distributor upload status
-- distributor run status, status polling error, and raw run report JSON when available
-- weatherreporter-owned idempotency conflict error when applicable
+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.
 
-## Boundaries
+## Status and errors
 
-`internal/adapters/distributor` is the only weatherreporter package that imports
-`gitea.maximumdirect.net/eric/distributor/pkg/upload` or
-`gitea.maximumdirect.net/eric/distributor/pkg/bundle`.
+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.
 
-The app layer passes weatherreporter-owned request values to the adapter. The
-adapter does not choose report types, render templates, select output copies,
-configure destinations, wait for downstream publication, transform Markdown, or
-persist notification state.
+Status lookup or polling errors are preserved in `UploadResult.StatusError` so
+the caller can report 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.
 
-Full upstream distributor package and HTTP contract details stay under
-`docs/integrations/distributor/`.
+## Verification
 
-## Config Fields Used
+Focused tests cover configuration validation, request mapping, timeouts and
+polling, status translation, conflict handling, and token redaction:
 
-The adapter is built from `notify.distributor` config:
-
-- `endpoint`
-- `token_env`
-- `timeout`
-
-The app layer renders pipeline ID, bundle ID, idempotency key, and bundle paths
-from:
-
-- `pipeline_id_template`
-- `bundle_id_template`
-- `idempotency_key_template`
-- `report_path_templates`
-
-The token value is read from the environment variable named by `token_env`
-after config loading and `secrets.directory` processing.
-
-## Upload Behavior
-
-The adapter calls distributor `UploadFiles` with one or more file mappings:
-
-- pipeline ID: the rendered distributor workflow selector
-- source path: the managed Markdown report path selected by app orchestration
-- bundle paths: rendered bundle-relative report paths
-- created: the report generation timestamp
-
-The adapter creates a distributor upload client with the configured endpoint,
-bearer token, and timeout-backed HTTP client. It also wraps the upload context
-with the configured timeout when the timeout is greater than zero.
-
-After upload acceptance, the adapter polls distributor `Status` for the accepted
-run ID until the run reaches `succeeded` or `failed`, or until the configured
-timeout expires. It returns the latest status, error text, and raw report JSON in
-weatherreporter-owned types so app orchestration can persist them in the
-notification debug artifact. Status lookup failures or timeout before a terminal
-state are kept as debug status errors on an otherwise accepted upload. A
-terminal distributor run status of `failed` is returned as a notification failure
-with the status report preserved.
-
-## Failure Behavior
-
-The adapter validates required endpoint, token env name, token value, pipeline
-ID, bundle ID, idempotency key, upload files, source paths, bundle paths, and
-upload client inputs before uploading.
-
-Upload failures include endpoint, pipeline ID, bundle ID, idempotency key,
-source paths, and bundle paths context. Token values are redacted from adapter
-errors.
-
-Distributor idempotency conflicts are exposed as a weatherreporter-owned
-`IdempotencyConflictError`, so callers do not depend on upstream distributor
-types.

-- `internal/cli/root_test.go`
-
-Adapter tests use a fake upload client factory and do not require a live
-distributor service.
-
-## Invariants
-
-- Distributor package types do not leak outside the adapter.
-- Only the managed Markdown report is uploaded.
-- The adapter never scans the workspace.
-- Token values are not included in errors, CLI output, metadata, docs, or
-  examples.

 # Fact Contracts Internals
 
-This document describes the fact contract boundary.
+`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).
 
-## Purpose
+## Collected facts
 
-`internal/facts` separates normalized upstream facts collected for a report run
-from conservative report-scoped facts derived from them. The package gives app
-orchestration one place to build reusable facts before module execution.
+`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.
 
-## Inputs And Outputs
+A nil bundle produces an empty collected value. Collection itself, missing
+source policy, and source hashes are outside this package.
 
-Inputs:
+## Report-scoped derivation
 
-- `weatherdata.Bundle` from the Weather API adapter
-- resolved report definition and valid period
-- report timezone
-- configured daypart definitions
+`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.
 
-Outputs:
+Report identity controls the summary shape:
 
-- `facts.CollectedFacts` with normalized source facts plus separate source
-  provenance and warnings
-- `facts.DerivedFacts` with valid-period forecast slices, alert overlaps,
-  daily summaries, daypart summaries, and Storm Report window summary
+| 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 |
 
-## Boundaries
+`DaypartSummaries` is collected from the resulting daily summaries.
+The detailed grouping, daypart-window, and alert rules are owned by
+[forecast derivation](forecast-derivation.md).
 
-- This package owns fact assembly and reusable deterministic derivation for a
-  report run.
-- It does not fetch upstream data, build prompt wording, compare prior
-  snapshots, write workflow state, invoke Scriptorium, or define modules.
+## Missing data and failures
 
-## Config Fields Used
+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.
 
-- `dayparts[].name`
-- `dayparts[].start`
-- `dayparts[].end`
-- `weather_api.timezone`
+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.
 
-## External Adapters Used
+## Verification and invariants
 
-None directly. Collected facts are built from `weatherdata.Bundle`.
+Focused tests cover collected-fact separation, report-period selection,
+hourly behavior, daily summaries, and convective outlook selection:
 
-## State Or Manifest Behavior
+```sh
+go test ./internal/facts
+```
 
-None. Source provenance and warnings remain data fields for downstream metadata
-and inspection.
-
-## Failure Behavior
-
-- Invalid or missing report valid periods return an error.
-- Invalid timezone names return an error.
-- Missing required hourly forecast data returns the underlying forecast
-  derivation error for reports that require daily summaries.
-- Missing optional narrative, alert, discussion, daily, or weather story data
-  produces empty or nil derived fields.

-## Tests

-- Derived facts are scoped to one resolved report.
-- Source provenance and warnings stay separate from ordinary fact fields.
-- Prompt-specific wording and one-off presentation decisions stay outside this
-  package.
+Facts are derived once for a resolved report from already collected data.
+They remain reusable structured values for prompt input and template
+presentation, which are owned elsewhere.

 # Forecast Derivation Internals
 
-This document describes deterministic forecast summarization in
-`internal/forecast`.
+`internal/forecast` deterministically selects and summarizes normalized
+forecast data. It has no transport, filesystem, CLI, subprocess, or report
+registry dependency. Its summaries are consumed by
+[fact contracts](facts.md) and later module builders.
 
-## Purpose
+## Period and daypart semantics
 
-`internal/forecast` converts normalized weather data into daily and period
-summaries used by fact builders and module builders.
+Selections use `timeutil.Period` half-open overlap: a value is selected only
+when both intervals share time. `BuildDailySummary` creates one local civil
+day; `BuildPeriodDailySummaries` intersects every local civil day with the
+requested period, preserving partial first and last days.
 
-## Inputs And Outputs
+`ResolveDayparts` converts each configured name, start clock, and end clock
+into a local window. An end clock at or before its start clock wraps into the
+next civil day. The daypart and timezone defaults are defined in the
+[configuration reference](../config.md), not here.
 
-Inputs:
+## Deterministic summaries
 
-- `weatherdata.Bundle`
-- local date or resolved report period
-- timezone
-- configured daypart definitions
+`BuildDailySummary` requires an hourly run with at least one period. It adds
+the selected narrative periods, discussion, alert overlaps, source provenance,
+source warnings, and one `DaypartSummary` per resolved window. A daypart keeps
+its selected hourly periods and derives temperature and apparent-temperature
+ranges, timed precipitation and wind maxima, dominant and notable conditions,
+and weather indicators.
 
-Outputs:
+Indicators are deterministic checks over normalized values and condition text:
+heat, cold, and wind use package-owned numeric cutoffs; snow, ice, fog, and
+wind text are detected from the forecast description. `BuildPrecipTiming`
+sorts periods, records the maximum and first precipitation, groups contiguous
+periods at or above its package-owned probability threshold, and records
+thunder mentions.
 
-- `forecast.DailySummary` for one local civil day
-- one clipped daily summary per local day or partial day from
-  `BuildPeriodDailySummaries`
-- daypart summaries with selected hourly periods, ranges, timed maximums,
-  conditions, indicators, and alert overlaps
+Alert overlap parsing supports the normalized alert payload's available timing
+fields. Unparseable alerts and invalid intervals are ignored; valid overlaps
+are clipped to the requested period and ordered by alert start time.
 
-## Boundaries
+## Missing data and failures
 
-- This package groups, selects, and summarizes already-normalized forecast
-  data.
-- It does not perform HTTP calls, parse CLI flags, resolve report definitions,
-  compare prior snapshots, build prompt input packages, or invoke Scriptorium.
+Empty selections yield empty summary fields rather than generated prose.
+Direct daily or period-summary calls fail when their required bundle, valid
+period, hourly data, or daypart definitions are invalid. A nil location uses
+UTC when these APIs are called directly. Optional narrative, discussion, and
+alerts remain absent when their normalized products are absent.
 
-## Config Fields Used
+Forecast thresholds used for brief indicators and precipitation timing are
+implementation rules.
 
-- `dayparts[].name`
-- `dayparts[].start`
-- `dayparts[].end`
+## Verification and invariants
 
-Threshold constants for basic indicators live in forecast code rather than
-configuration.
+Focused tests cover local civil days, clipped periods, daypart resolution,
+summary metrics, precipitation windows, threshold helpers, and alert overlap:
 
-## External Adapters Used
+```sh
+go test ./internal/forecast ./internal/timeutil
+```
 
-None directly. Forecast data arrives through `weatherdata.Bundle`.
-
-## State Or Manifest Behavior
-
-None. Source warnings and provenance from the bundle are carried into summaries
-for later metadata and module output.
-
-## Skip And Resume Behavior
-
-None. Missing optional source context can produce empty selections, but missing
-required hourly data fails summarization.
-
-## Failure Behavior
-
-- A nil bundle or missing hourly forecast data returns an error.
-- Invalid daypart definitions return parse errors with context.
-- Alert records without parseable RFC3339 timing are skipped.
-- Empty selected periods produce empty summaries rather than generated prose.
-
-## Tests

-- Weather facts come from normalized source data.

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

+## Verification and invariants

+Focused tests cover the catalog, each report-specific validator, normalization,
+schema/template mismatches, context construction, optional modules, and typed
+stanza errors:
+
+```sh
+go test ./internal/generatedtext

+
+Generated text supplies prose slots only; deterministic weather facts remain in
+module and fact values. Every report definition must resolve to exactly one

 # Module Contract Internals
 
-This document describes the module contract in `internal/module`.
+`internal/module` defines the stable envelope between report composition,
+module builders, in-memory snapshots, 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).
 
-## Purpose
+## Outputs and snapshots
 
-`internal/module` defines the shared identifiers and data envelopes used for
-prompt-facing modules. Report definitions use module IDs for composition,
-module builders produce outputs with stanza names, prompt input packages consume
-snapshots, and Recent Changes compares snapshot stanzas.
+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 value.
 
-## Inputs And Outputs
+`NewSnapshot` builds the ordered `weatherreporter.modules.v1` snapshot and
+validates it. Its JSON representation contains 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.
 
-Inputs:
+Snapshots reject missing schema versions, empty IDs or stanza names, and
+duplicate IDs or stanza names. Output order is caller-owned and preserved.
 
-- ordered `module.ConfigItem` values from report definitions or config
-  overrides
-- `module.Output` values produced by module builders
+## Registered IDs and default composition
 
-Outputs:
+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`.
 
-- stable `module.ID` constants
-- typed option structs for registered modules
-- `module.Snapshot` with schema version `weatherreporter.modules.v1`
-- ordered snapshot outputs with module ID, stanza name, and typed value
-- typed stanza lookup through `module.StanzaValue`
+The registry declares these ordered default compositions:
 
-## Registered Module IDs
+| Report | Ordered modules |
+| --- | --- |
+| Daily | metadata, current conditions, narrative forecast, daily summary, daypart summaries, precipitation timing, alert digest, SPC outlooks, AFD (long term), SPC discussion, weather story, outdoor windows, daily planning, hourly forecast |
+| Today | metadata, current conditions, narrative forecast, daily summary, daypart summaries, precipitation timing, alert digest, SPC outlooks, AFD, SPC discussion, weather story, outdoor windows, hourly forecast, today planning |
+| Tomorrow | metadata, current conditions, narrative forecast, daily summary, daypart summaries, precipitation timing, alert digest, SPC outlooks, AFD, SPC discussion, weather story, outdoor windows, tomorrow planning, hourly forecast |
+| Hourly | metadata, current conditions, hourly forecast, precipitation timing, alert digest, SPC outlooks, AFD (key messages and short term), SPC discussion, weather story |
 
-The registry recognizes these IDs:
+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.
 
-- `metadata`
-- `current_conditions`
-- `narrative_forecast`
-- `hourly_forecast`
-- `derived_daily_summary`
-- `derived_daypart_summaries`
-- `precip_timing`
-- `alert_digest`
-- `area_forecast_discussion`
-- `weather_story`
-- `outdoor_windows`
-- `tomorrow_planning`
+## Rich and prompt-facing values
 
-Every registered module has a builder. Report composition entries that refer to
-unknown or unimplemented module IDs fail validation instead of being skipped.
+Rich values remain available to module snapshots 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).
 
-## Options
+## Verification and invariants
 
-Most modules use an empty options struct. `area_forecast_discussion` accepts:
+Focused tests cover snapshot validation and order, typed stanza lookup, and
+prompt-value fallback:
 
-```yaml
-sections:
-  - product
-  - key_messages
-  - short_term
-  - long_term
+```sh
+go test ./internal/module
 ```
 
-An omitted or empty `sections` list includes all available discussion sections.
-Invalid option shapes fail during config normalization or composition
-validation.
-
-## Boundaries
-
-- This package owns module identifiers, config item envelopes, output
-  envelopes, snapshot validation, and typed stanza lookup.
-- It does not define report IDs, execute builders, fetch weather data, derive
-  forecast facts, write state, or invoke Scriptorium.
-
-## State Or Manifest Behavior
-
-`module.Snapshot` values are persisted by `internal/state` as JSON. Snapshot
-validation rejects missing schema version, missing module IDs, missing stanza
-names, duplicate module outputs, and duplicate stanza names while preserving
-output order.
-
-## Failure Behavior
-
-- Snapshot construction fails for duplicate module outputs or duplicate stanza
-  names.
-- Typed stanza lookup returns `found=false` for missing stanzas.

 # Prompt Input Internals
 
-This document describes YAML prompt data package construction in
-`internal/promptinput`.
+`internal/promptinput` converts report metadata, an ordered module snapshot, and source warnings into the YAML `data_package` supplied inline to Promptkit. It owns the package schema, grouping, serialization, loading, and validation; it does not choose an output destination, collect weather, execute a provider, or retain packages after a command ends.
 
-## Purpose
+## Package Construction
 
-`internal/promptinput` converts report metadata, an ordered module snapshot,
-Recent Changes, and source warnings into the `data_package` file passed to
-Scriptorium.
+`Build` produces `weatherreporter.data_package.v4`. It copies the run ID; report ID, variant, prompt ID, generation time, timezone, local current date, and valid period; ordered briefing stanzas; and source warnings. Prompt input contains no historical comparison section.
 
-The persisted data package is YAML with schema version
-`weatherreporter.data_package.v2`. It is separate from the JSON module snapshot
-used for inspection and comparison.
+Briefing is a flat ordered set of stanza values. `Build` uses each output's `DataPackageValue`, so curated prompt exports take precedence and rich values are used only as a fallback. Prompt exports are selected by the [briefing registry](briefing.md), while the rich-versus-prompt contract is in [module internals](module.md).
 
-## Inputs And Outputs
+## YAML Ordering And Validation
 
-Inputs:
+Serialization keeps `metadata` directly under `briefing`. Every other known stanza is placed in one category and emitted in category order while preserving its original module order:
 
-- report metadata from app/state orchestration
-- `module.Snapshot`
-- optional `[]changes.Change`
+| Category | Current stanzas |
+| --- | --- |
+| `applicable_risk_products` | alert digest, SPC convective outlooks |
+| `derived_summaries` | deterministic summaries, precipitation timing, outdoor windows, and planning values |
+| `narrative_products` | narrative forecast, discussions, and weather story |
+| `raw_data` | current conditions and hourly forecast |
 
-Outputs:
+`LoadYAML` accepts this layout and reconstructs the flat order and values. It rejects misplaced, duplicate, unknown, or uncategorized stanzas. `Validate` requires the v4 schema version, report identity and period fields, and at least one ordered briefing stanza. `MarshalYAML` and `LoadYAML` validate their result. `Save` remains a reusable atomic-file helper for callers that explicitly need one; normal application execution passes marshalled YAML directly to Promptkit.
 
-- `promptinput.Package` with schema version, RunID, report metadata, named
-  module stanzas grouped for prompt presentation, Recent Changes, and source
-  warnings
-- YAML bytes from `promptinput.MarshalYAML`
-- YAML file written atomically by `promptinput.Save`
+Focused tests cover construction, curated exports, category ordering, YAML round trips, invalid layout, validation, and atomic saves:
 
-The YAML shape includes:
-
-```yaml
-schema_version: weatherreporter.data_package.v2
-run_id: <run_id>
-report:
-  id: <report_id>
-  prompt_id: <prompt_id>

+```sh

 ```
-
-The `briefing` mapping keeps `metadata` directly under `briefing` and groups
-weather module stanzas under prompt-facing categories. This grouping is a YAML
-presentation concern only: module snapshots remain flat, and loaded
-`promptinput.Package` values expose flat stanza names in `Briefing.Values`.
-Within each category, stanza order follows the module snapshot output order.
-
-Current categories are:
-
-- `applicable_risk_products`: location-applicable alerts, warnings, outlooks,
-  discussions, and similar risk products.
-- `derived_summaries`: deterministic summaries and calculated report facts.
-- `narrative_products`: official narrative text products and forecast stories.
-- `raw_data`: minimally transformed underlying weather data.
-
-## Boundaries
-
-- This package owns prompt package schema, YAML marshaling, YAML loading, and
-  validation.
-- It does not fetch weather data, derive forecast summaries, execute modules,
-  find prior snapshots, compare changes, choose artifact paths, or invoke
-  Scriptorium.
-
-## Config Fields Used
-
-None directly. Config-derived values such as timezone, units, and prompt
-location are already present in report metadata and module stanzas before this
-package runs.
-
-## External Adapters Used
-
-None.
-
-## State Or Manifest Behavior
-
-`promptinput.Save` writes YAML atomically. Managed workspace paths are owned by

-
-None. Recent Changes is always present as an `items` list and may be empty.
-
-## Failure Behavior
-
-Validation fails before render preflight when required top-level fields are

+# Promptkit Adapter Internals
+
+`internal/adapters/promptkit` maps Weatherreporter's project-owned executor contract to Promptkit. The CLI maps `promptkit` configuration to a `PromptExecutorConfig` and constructs one executor per action. Promptkit dependency types do not escape the adapter.
+
+The adapter supplies Weatherreporter's embedded prompt, schema, and fallback profile filesystems to each engine. Promptkit resolves configured operator profile sources, the embedded fallback catalog, and its built-in catalog; the adapter does not parse profile YAML, merge sources, or probe endpoints.
+
+The adapter exposes exact prompt and profile validation plus prepared execution. It maps safe prompt identity, logical profile, effective backend/model, preparation, execution, validation, and optional debug values into `promptexec`. `Execute` passes the YAML package as an inline Promptkit input; it does not construct a filesystem URI or write a package file.
+
+The application uses the preparation callback to record active safe provenance in memory and optionally writes content-rich diagnostics only through an explicit debug writer. The adapter returns raw output for application validation and rendering. It does not retain application state, render Markdown, choose report definitions, or send Distributor notifications.
+
+Focused tests:
+
+```sh
+go test ./internal/adapters/promptkit ./internal/cli ./internal/app

+The public logical prompt/profile/schema contract is owned by the [Promptkit integration guide](../integrations/promptkit.md).

-All report definitions are eligible for generation.
+Daily derives its filename from the resolved valid-period start in the effective timezone, so multiple Daily items have distinct destinations. Exact template fields and schema assets belong to [report templates](../templates.md) and [generated-text internals](generatedtext.md). Prompt assets own default profile selection; the registry stores no provider setting.
 
-## Valid Periods
+## Collaborators And Boundaries
 
-- Daily Today covers the selected local civil day, or the current local civil
-  day when no date override is supplied.
-- Daily Tomorrow covers the next local civil day from generation time.
-- 3-Day Outlook covers the interval from generation time through local midnight
-  three days later.
-- Weekend Outlook covers the upcoming weekend window and is not scheduled for
-  Sunday morning batch resolution.
-- Storm Report covers an explicit event window supplied by the caller.
+`DefaultRegistry`, `Lookup`, `Resolve`, and report-name helpers prevent callers from duplicating report identity rules. Registry overrides clone a recognized definition and replace its module list. `DistributorPathTemplates` are consumed by app orchestration; their rendered external bundle-path contract is documented in the [Distributor bundle guide](../integrations/distributor/pkg-bundle.md).
 
-Storm event windows can be parsed from local `YYYY-MM-DDTHH:MM` timestamps in
-the configured timezone or RFC3339 timestamps with explicit offsets. End time
-must be after start time.
+`morning` and `evening` are registry-owned batch names. Fixed flags declare Today and Tomorrow eligibility; app orchestration determines data-dependent Daily membership and the actual batch plan.
 
-## Boundaries
+The registry never collects weather data, parses CLI flags, writes output, executes Promptkit, or delivers a report.
 
-`internal/report` defines report metadata and time coverage. It does not fetch
-weather data, build module values, compare snapshot contents, write state,
-parse CLI flags, or invoke Scriptorium.
+Focused tests cover definition completeness, command and alias lookup, period resolution, run IDs, output names, composition defaults, and override validation:
 
-The CLI owns public command names. The app maps those command names to report
-IDs, then uses the registry for report policy.
-
-## Config Fields Used
-
-The app supplies `weather_api.timezone` as a loaded `time.Location`. Batch
-output path copying uses batch output names from report definitions.
-
-## State And App Usage
-
-- State paths use `ArtifactGroup`.
-- Batch output copies use `BatchOutputName`.
-- Generation checks `Generated`.
-- Module composition defaults use `Modules`.
-- Prior lookup checks `CompatiblePriorIDs` and the comparison strategy.
-- RunIDs include the resolved report ID.
-
-## Failure Behavior
-
-- Unknown report IDs and batch names return actionable errors.
-- Weekend Outlook resolution returns an error when resolved directly on Sunday.
-- Storm Report resolution requires start and end, with end after start.
-
-## Tests
-
-Inspect:
-
-- `internal/report/period_test.go`
-- `internal/app/app_test.go`
-- `internal/cli/root_test.go`
-
-## Invariants
-
-- Report selection goes through the registry.
-- Daily Today and Daily Tomorrow both use `weather.daily_report`.
-- Valid periods are half-open intervals independent of rendered report text.
-- Artifact grouping, batch output filenames, generated-report eligibility,
-  default module composition, comparison compatibility, and comparison strategy
-  are declared by report definition.

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

-# Scriptorium Adapter Internals
-
-This document describes the subprocess adapter in
-`internal/adapters/scriptorium`.
-
-## Purpose
-
-The adapter runs `scriptorium render` for prompt preflight and `scriptorium run`
-for Markdown report generation. It isolates subprocess execution, argv
-construction, timeout handling, output capture, and exit-code interpretation
-from app and domain packages.
-
-## Inputs And Outputs
-
-Inputs:
-
-- prompt ID
-- YAML prompt input data package path
-- report output path for `run`
-- configured binary, config path, profile, timeout, and extra arguments
-- context for cancellation
-
-Outputs:
-
-- argv used for execution
-- captured stdout and stderr
-- truncation flags for captured output
-- exit code
-- report output path for `run`
-
-## Boundaries
-
-`internal/adapters/scriptorium` owns Scriptorium command construction and
-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.
-State persistence uses a state-owned preflight artifact shape; app
-orchestration converts render results before saving.
-
-## Config Fields Used
-
-- `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`.
-- The file at the data package path is YAML produced by `internal/promptinput`.
-- 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`.
-
-## Purpose
-
-`internal/state` owns managed workspace paths, atomic JSON writes, persisted
-metadata, prior snapshot lookup, and read-only artifact inspection helpers.
-
-## Inputs And Outputs
-
-Inputs:
-
-- workspace configuration
-- resolved report definition and valid period
-- module snapshot
-- prompt input data package
-- preflight artifact
-- rendered report path preparation request
-- RunID for inspection lookups
-
-Outputs:
-
-- module snapshot JSON path
-- prompt input data package YAML path
-- render preflight JSON path
-- managed Markdown report path
-- metadata JSON path
-- prior comparable snapshot metadata
-- loaded module snapshot or data package
-- recent report records for inspection
-
-## Boundaries
-
-`internal/state` owns local filesystem layout, path validation, durable writes,
-metadata reads, prior lookup, and report listing. It does not fetch weather
-data, derive forecasts, build prompt input content, compare module contents,
-invoke Scriptorium, import adapter result types, or parse CLI flags.
-
-Preflight persistence uses the state-owned `PreflightArtifact` shape. The app
-converts adapter render results into that shape before saving.
-
-## Config Fields Used
-
-- `workspace.root`
-- `workspace.snapshots_dir`
-- `workspace.reports_dir`
-- `workspace.data_packages_dir`
-- `workspace.preflight_dir`
-- `workspace.notifications_dir`
-
-Workspace subdirectories must be relative paths that stay under
-`workspace.root`.
-
-## Managed Layout
-
-Paths are derived from the resolved report definition's artifact group, the
-valid-period start date for dated artifacts, and the RunID.
-
-```text
-<workspace.root>/
-  snapshots/<artifact_group>/<YYYY-MM-DD>/<run_id>.modules.json
-  snapshots/<artifact_group>/<YYYY-MM-DD>/<run_id>.metadata.json
-  data-packages/<artifact_group>/<YYYY-MM-DD>/<run_id>.data_package.yaml
-  preflight/<artifact_group>/<YYYY-MM-DD>/<run_id>.render.json
-  notifications/<artifact_group>/<YYYY-MM-DD>/<run_id>.distributor.json
-  reports/<artifact_group>/<run_id>.md
-```
-
-Metadata is stored beside module snapshots and links the module snapshot, data
-package, preflight, report paths, notification path when attempted, and
-configured prompt location. Report listing walks metadata files under the
-snapshots directory.
-
-## Prior Lookup
-
-Prior snapshot lookup reads stored metadata through the shared lookup path and
-selects the latest earlier snapshot whose report ID is compatible with the
-current report definition.
-
-- Daily Today and Daily Tomorrow are compatible with each other for the same
-  valid local date.
-- 3-Day Outlook compares with prior 3-Day snapshots for the same valid local
-  date.
-- Weekend Outlook compares with prior Weekend snapshots for the same weekend
-  window.
-- Storm Report has no prior lookup because explicit event-window comparison is
-  not searched by the filesystem store.
-
-## 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.
-Distributor notification debug artifacts are written atomically when
-notification is attempted and include rendered distributor pipeline ID, bundle
-ID, idempotency key, bundle paths, upload status, latest run status, and
-redacted errors.
-
-Inspection helpers read existing metadata, module snapshot, 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 `weatherdata.Bundle`.
+`internal/weatherdata` owns the normalized, wire-independent weather bundle
+that passes from collection through rendering. The Weather API
+adapter translates provider responses into these types; its request, response,
+and availability contract is documented in the
+[Weather API integration guide](../integrations/weatherapi.md).
 
-## Purpose
+## Bundle contract
 
-`internal/adapters/weatherapi` fetches normalized weather data from one
-configured Weather API endpoint and assembles the bundle consumed by forecast
-derivation and module builders. Module builders expose normalized current
-conditions and weather story context when those sources are available.
+`Bundle` has a collection timestamp (`FetchedAt`), source provenance
+(`Sources`), and collection-level warnings (`Warnings`). Its product fields are
+optional so an allowed missing source can be represented without manufacturing
+weather data.
 
-## Inputs And Outputs
+| Field | Normalized product |
+| --- | --- |
+| `Observation` | Station observation |
+| `Current` | Current conditions |
+| `Hourly` | Hourly forecast periods |
+| `Narrative` | Narrative forecast |
+| `Alerts` | Active-alert check, including an explicitly empty result |
+| `Discussion` | Forecast discussion and its time-range sections |
+| `Daily` | Daily forecast periods when supplied |
+| `WeatherStory` | Latest weather story |
+| `SPCConvectiveOutlooks` | Convective outlook run, discussions, and GeoJSON geometry |
 
-Inputs:
+The bundle carries values rather than provider request details. Consumers use
+it to construct report facts and data packages; they should not infer a
+provider endpoint or retry policy from the normalized types. See
+[collection](collect.md) for assembly and
+[report templates](../templates.md) for the values exposed to authors.
 
-- `config.Config` with Weather API URL, timeout, format, units, timezone,
-  precision, and missing-source policy
-- HTTP responses using the Weather API `data` envelope
+## Source provenance
 
-Outputs:
+Every checked source is represented by a `Source` entry. The record identifies
+the source (`Name`), request location and query (`Endpoint`, `Query`), fetch
+time, provider issue and update times when available, a SHA-256 digest of the
+source data, and whether the source was unavailable (`Missing`). Its warnings
+stay with that source in addition to the bundle-level warning list.
 
-- `weatherdata.Bundle` with observation, current conditions, hourly forecast,
-  narrative forecast, active alerts, discussion, latest weather story, source
-  records, and source warnings
-- optional saved bundle JSON through app fetch helpers
+An empty product can be meaningful checked data. For example, an explicit
+empty alerts result is not missing and retains its source hash. A source is
+marked missing only when the adapter's missing-source policy treats the
+response or parsing failure as unavailable. The policy itself belongs to the
+[configuration reference](../config.md).
 
-## Boundaries
+## Warning semantics
 
-- The adapter owns HTTP calls, response-envelope handling, source hashing, and
-  decoding into internal bundle types.
-- It does not derive dayparts, resolve report periods, build module values, compare
-  snapshots, write report state, or invoke Scriptorium.
+`SourceWarning` has a source name, stable code, severity, explanatory message,
+endpoint, and `CompletenessImpact`. When collection proceeds with a warning,
+the same warning appears in `Source.Warnings` and `Bundle.Warnings` so both
+local provenance and whole-run consumers see it. A policy that treats a missing
+source as an error returns no partial bundle.
 
-## Config Fields Used
+Warnings describe data completeness, not rendering or delivery failures.
+Those failures are reported by [application orchestration](app-orchestration.md).
 
-- `weather_api.base_url`
-- `weather_api.timeout`
-- `weather_api.format`
-- `weather_api.units`
-- `weather_api.timezone`
-- `weather_api.precision`
-- `missing_source.default`
-- `missing_source.sources`
+## Boundaries and verification
 
-## External Adapters Used
+This package defines data shapes and has no HTTP client, configuration loader,
+filesystem access, or template behavior. Focused tests cover the normalized
+types and the Weather API adapter verifies translation into them:
 
-- Weather API HTTP service
-
-See [Weather API integration](../integrations/weatherapi.md) for the external
-contract used by this project.
-
-## State Or Manifest Behavior
-
-The adapter records source name, endpoint, query, fetch time, source timestamps
-when available, SHA-256 hash over compact raw `data` JSON, missing status, and
-source warnings. 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 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.
-- Source provenance and warnings remain inspectable downstream.

 # Weatherreporter Operations
 
-This guide covers normal operation, generated artifacts, inspection, recovery,
-and operational caveats. For symptom-specific diagnosis, see
-[Troubleshooting](troubleshooting.md).
+This guide covers normal output handling, Distributor notification, secure
+prompt diagnostics, and cleanup of legacy application state. See the [CLI
+reference](cli.md) for command syntax and the [configuration reference](config.md)
+for fields, defaults, and notification templates.
 
-## Normal Workflow
+## Normal Operation
 
-Generation commands:
+After configuring a Weather API endpoint, generate one report:
 
-```text
-weatherreporter generate daily --date 2026-05-29
-weatherreporter generate tomorrow
-weatherreporter generate three-day
-weatherreporter generate weekend
-weatherreporter generate storm --start 2026-05-29T18:00 --end 2026-05-30T06:00
+```sh
+weatherreporter generate today
 ```
 
-Each command resolves a report period, fetches a Weather API bundle, builds a
-JSON module snapshot, builds a YAML prompt input data package, runs
-`scriptorium render`, runs `scriptorium run`, and writes managed artifacts under
-the configured workspace.
-When distributor notification is enabled, weatherreporter uploads the managed
-Markdown report after `scriptorium run` succeeds and final metadata is saved.
-`--out PATH` writes an extra Markdown copy for the current generated report; it
-is not used as the distributor upload source.
+With no configured output directory, the command writes `today.md` in the
+current directory. Set `output.directory` to use one ordinary publication
+directory for reports, or choose a one-command operator-owned file with
+`--out`; a relative path is resolved from the current directory and an absolute
+path is used directly. The explicit flag takes precedence over the configured
+directory. Weatherreporter renders in memory and atomically replaces the
+selected destination only after generation and rendering succeed. It does not
+create a default workspace, metadata, receipts, or intermediate output files.
 
-Batch commands:
+A missing configured directory is created only as part of successful report
+publication. If its existing path is not a directory or cannot be inspected,
+the command stops before prompt inspection or weather collection, leaving any
+existing report unchanged. See the [configuration reference](config.md) for the
+field definition and validation rules.
 
-```text
-weatherreporter run morning
-weatherreporter run evening
+Before a destination is published, provider, validation, rendering, write, and
+cancellation failures leave an existing report unchanged. A notification
+failure happens after publication, so retain and use the completed Markdown
+file while resolving the delivery error. The JSON result identifies the
+absolute output path and active profile, backend, model, warnings, validation,
+debug, and notification information; see the [CLI reference](cli.md) for its
+exact fields.
+
+## Batch Outputs And Distributor Notification
+
+Run a scheduled batch with an explicit output directory when appropriate:
+
+```sh
+weatherreporter run morning --out-dir ./reports
 ```
 
-`run morning` generates Daily Today and the 3-Day Outlook, plus Weekend Outlook
-except on Sunday. `run evening` generates the Tomorrow Planning Brief. Batch
-commands print a JSON summary to stdout, write compact per-report status lines
-to stderr, continue independent reports after one report fails, and return
-nonzero when any report failed. When notification is configured, the summary and
-status lines include notification status, accepted distributor run ID, or
-notification error fields for each attempted report. `--out-dir PATH` writes
-extra Markdown copies using report default filenames such as `daily.md`,
-`three-day.md`, `weekend.md`, and `tomorrow.md`; these copies are not used as
-distributor upload sources.
+Without `--out-dir`, batch reports are written beneath `output.directory` when
+configured, otherwise the current directory. The explicit directory applies
+only to that command and takes precedence over the configured fallback.
+Morning runs Today, Tomorrow, and every eligible dated Daily Report; evening
+runs Tomorrow and the same eligible Daily Reports. Eligible Daily dates begin
+after tomorrow and require complete hourly coverage for their local civil day.
+A batch collects once, determines the complete report set, and validates every
+final output destination before executing its first report prompt. A destination
+collision, such as a directory named `tomorrow.md`, stops the batch before any
+report output is created or replaced. After successful validation, each selected
+report processes independently and successful outputs remain available if
+another report fails.
 
-## Filesystem Layout
+When `notify.distributor.enabled` and batch notification are enabled,
+Weatherreporter sends one Distributor upload only after every selected output
+exists. If an item fails, the batch notification is skipped and successful
+files remain at their selected destinations. A batch notification failure also
+leaves all successfully published report files in place. Distributor source
+files are those operator-owned Markdown outputs; rendered bundle paths and
+delivery status appear in the result, not in a local notification receipt.
+Report counters count report items only. A batch notification failure therefore
+returns a failed batch status even when all report counters show success; the
+top-level notification result contains the delivery diagnostic.
 
-The default workspace root is `workspace`.
+For a single report, Distributor notification follows the atomic output write.
+See the [configuration reference](config.md) for pipeline, bundle,
+idempotency-key, and per-report path templates.

+## Local Prompt Profile Override
+
+Hourly normally selects the embedded `weather-light` profile. To use a local
+OpenAI-compatible model without changing prompts or application code, copy
+[weather-light-local-profile.yml](../examples/weather-light-local-profile.yml),
+set its `endpoint` and `model` for the local server, and configure the copy as
+`promptkit.profile_file`. The profile file's `weather-light` definition
+completely replaces the embedded definition; it does not affect a report that
+selects another profile ID.
+
+Prompt and profile validation occurs before weather collection. A malformed
+profile file, missing required credential, or unsupported selected backend
+stops the command before collection. A reachable profile can still fail later
+if its local model endpoint is unavailable; Weatherreporter does not switch to
+a remote profile.
+
+## Optional Prompt Debug Capture
+
+Use `--llm-debug-dir` only when content-rich prompt diagnostics are required:
+
+```sh
+weatherreporter generate today --llm-debug-dir /var/tmp/weatherreporter-debug
 ```
 
-Managed artifact filenames use the RunID, so repeated runs for the same valid
-period do not overwrite each other.
+The directory must be absolute. Requested captures are written with restrictive
+permissions beneath the supplied directory, organized by report and run. They
+can contain rendered prompts and generated output, so limit access to trusted
+operators and remove the captures when they are no longer needed. Normal output,
+summaries, and routine logs omit that sensitive content. Debug capture is never
+created for an ordinary command without `--llm-debug-dir`.
 
-## RunID And Metadata
+If capture creation or writing fails, the affected run fails rather than
+silently continuing without the requested diagnostics.
 
-RunIDs are based on generation time plus report ID:
+## Diagnosing Failures
 
-```text
-20260529T100000.123456789Z_daily_today
+Start with the command error and JSON summary. For a report generation failure,
+the selected destination was not replaced; for a notification failure, inspect
+the completed destination and the notification result. For a batch failure,
+use the per-report statuses and retain successful output files. Enable explicit
+debug capture only when content-rich Promptkit diagnostics are necessary.
+
+Weatherreporter does not retain runs for later inspection, resume failed work,
+or provide automatic cleanup, archival, remote state, daemon operation, or
+automatic storm monitoring.
+
+## Manual Cleanup Of Legacy Workspaces
+
+Older installations may have a directory named `workspace` containing reports,
+snapshots, prompt inputs, or notification records from previous versions.
+Current commands neither read nor update it. After confirming that no separate
+retention requirement applies, remove that specific legacy directory manually;
+do not use a broad cleanup command that could remove current operator outputs.
+
+For example, from the directory that contains the old directory:
+
+```sh
+rm -rf ./workspace
 ```
 
-Each generated report writes metadata that links:
-
-- RunID, report ID, variant, and prompt ID
-- generation time, timezone, and valid period
-- source location, source hashes, and source warnings
-- module snapshot path
-- prompt input data package path
-- preflight output path
-- managed Markdown report path
-- distributor notification debug artifact path, when notification is attempted
-
-Batch summaries include report status, error text when applicable, notification
-outcome when attempted, valid period, and known artifact paths for each
-attempted report. Notification fields are `notificationStatus`,
-`notificationRunId`, and `notificationError`.
-
-## Distributor Notification
-
-Distributor notification is configured with `notify.distributor` and is
-disabled by default. When enabled, weatherreporter uploads the managed Markdown
-report path recorded in the report result and metadata. That single source file
-can be mapped to one or more configured bundle paths. By default, it is mapped
-to one dated report path. Extra copies written by `--out` or `--out-dir` are
-operator conveniences only.
-
-The rendered pipeline ID selects the configured distributor `http_upload`
-workflow. The default bundle ID is a stable logical source identity derived from
-producer name, location ID, and report ID:
-
-```text
-weatherreporter.{location_id}.{report_id}
-```
-
-The default idempotency key appends RunID to the rendered bundle ID so each
-report generation has a distinct retry identity. The default bundle path uses
-the valid-period start date, artifact group, and RunID. Distributor owns
-destination merge, retention, and derived snapshot behavior such as `latest`.
-
-Notification happens after final metadata save. Weather API, module snapshot,
-data-package, render preflight, Scriptorium run, and metadata-save failures do
-not trigger notification. A notification failure fails that report.
-In a batch, other reports continue, the failed report includes notification
-fields in the JSON summary, and the batch returns nonzero.
-
-Each notification attempt writes a debug artifact under `notifications/`. The
-artifact records the rendered pipeline ID, bundle ID, idempotency key, managed
-source path, bundle-relative paths, bundle created timestamp, accepted upload
-response, and the latest distributor run status response when available.
-Weatherreporter polls status until distributor reports `succeeded` or `failed`,
-or until the configured notification timeout expires. The run status includes
-the distributor status, error text, and raw run report JSON, which can show
-actions such as `replace_older`, `skip_same`, `skip_destination_newer`, or
-`failed`. Token values are not written.
-
-Weatherreporter is responsible for selecting the managed Markdown report,
-constructing a source bundle, and submitting it to the configured distributor
-HTTP endpoint. Distributor remains responsible for destination routing,
-publication, and any downstream Markdown-to-HTML transformation. Distributor
-leaves destination files alone when they are not tracked by a newly uploaded
-bundle, so existing uploaded dated report paths can remain available.
-
-## Inspection
-
-Inspection commands read existing workspace artifacts and emit JSON to stdout.
-They do not fetch weather data or run `scriptorium`.
-
-```text
-weatherreporter inspect reports --limit 10
-weatherreporter inspect metadata RUN_ID
-weatherreporter inspect modules RUN_ID
-weatherreporter inspect data-package RUN_ID
-weatherreporter inspect prior RUN_ID
-weatherreporter inspect sources RUN_ID
-```
-
-Use `inspect reports` to find RunIDs and artifact paths. Use
-`inspect metadata` to see the artifact links recorded for a run. Use
-`inspect modules` to review the persisted ordered module snapshot, and
-`inspect data-package` to review the structured prompt package used for
-rendering. Use `inspect prior` to see the prior comparable snapshot selected for
-Recent Changes, or `null` when none exists. Use `inspect sources` to review
-source provenance and warnings without dumping full weather payloads.
-
-## Recent Changes
-
-Recent Changes are computed from structured module snapshots, not rendered
-Markdown or YAML text.
-
-Daily Today and Daily Tomorrow can compare with each other when they cover the
-same valid local date. 3-Day Outlook compares with prior compatible 3-Day
-snapshots for the same valid local date. Weekend Outlook compares with prior
-compatible Weekend snapshots for the same weekend window. Storm Report leaves
-Recent Changes empty.
-
-When no prior comparable snapshot exists, or no configured threshold is crossed,
-`recentChanges.items` is empty.
-
-## Recovery
-
-A failed generation run may still leave useful artifacts:
-
-- If `scriptorium render` returns a result with a nonzero exit code, the
-  preflight JSON and metadata are written for inspection.
-- If `scriptorium run` exits nonzero after writing a report, the managed report
-  and metadata remain available.
-- If distributor notification fails, report artifacts and final metadata remain
-  available, but the report or batch command returns nonzero.
-- For batch commands, inspect the stdout JSON summary first, then inspect the
-  artifact paths for each failed report.
-
-For a bad report, start with:
-
-```text
-weatherreporter inspect metadata RUN_ID
-weatherreporter inspect sources RUN_ID
-weatherreporter inspect modules RUN_ID
-weatherreporter inspect data-package RUN_ID
-weatherreporter inspect prior RUN_ID
-```
-
-## Operational Caveats
-
-- The application uses one configured Weather API endpoint.
-- The application writes local filesystem state only.
-- The application does not implement resume, cleanup, archive, remote storage,
-  daemon operation, or automatic storm monitoring.
-- Generated reports and Scriptorium stderr can contain sensitive operational
-  context. Store workspace artifacts with appropriate filesystem permissions.
+This removal cannot be recovered by Weatherreporter. Keep or archive any
+historical files that are still needed before deleting them.

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

-# Development Policy
-
-This document is the contributor workflow policy for `weatherreporter`.
-Developers and LLM coding agents should use it with
-`docs/policy/architecture.md` and `docs/policy/documentation.md`.
-
-## Repository Layout
-
-- `cmd/weatherreporter`: binary entry point.
-- `internal/app`: orchestration for generation, batches, fetch helpers, and
-  inspection.
-- `internal/cli`: command parsing, flag handling, help text, and JSON output.
-- `internal/config`: configuration structs, defaults, loading, overrides, and
-  validation.
-- `internal/fileutil`: shared atomic filesystem write and copy helpers.
-- `internal/adapters/distributor`: Distributor upload adapter.
-- `internal/adapters/weatherapi`: Weather API HTTP adapter.
-- `internal/adapters/scriptorium`: Scriptorium subprocess adapter.
-- `internal/weatherdata`: normalized weather source facts, source metadata, and
-  source warnings.
-- `internal/forecast`: deterministic forecast derivation.
-- `internal/facts`: collected and derived report fact contracts.
-- `internal/module`: module IDs, config items, output envelopes, and snapshots.

-- `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/distributor ./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 distributor package types and upload-client construction inside
-  `internal/adapters/distributor`.
-- 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 dependencies:
-
-- `gitea.maximumdirect.net/eric/distributor` for distributor source bundle
-  construction and HTTP upload client behavior.
-- `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, Scriptorium, or distributor
-services.
-
-Preferred test patterns:
-
-- fake command runners for subprocess behavior;
-- `httptest.Server` for Weather API behavior;
-- fake distributor upload clients for notification 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, Scriptorium, or distributor
-  contract changes;
-- `docs/roadmap/` only for unimplemented or deferred work.
-
-Non-roadmap docs must describe implemented behavior only.

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

-## Required Documents
-
-### README.md
-
-**Audience:** users, administrators, operators
-
-The README is the outward-facing project orientation page.
-
-It should include, in order:
-
-1. concise description;
-2. elevator pitch;
-3. shortest useful command or usage example;
-4. links to targeted docs.
-
-The README should be short. It is not a manual.
-
-The “shortest useful command” means the simplest command that performs the project’s core use case. (It does not mean `app --help`.)
-
-### docs/policy/architecture.md
-
-**Audience:** developers, LLM coding agents
-
-`docs/policy/architecture.md` is required for every project.

-
-It should include:
-
-- project shape;
-- core design principles;
-- package and boundary philosophy;
-- state/persistence philosophy, if applicable;
-- external integration philosophy, if applicable;
-- error-handling and logging principles;
-- testing expectations;
-- documentation expectations;
-- architectural invariants;

-
-For small projects, this file may be brief. It may simply state that the project is intentionally narrow, monolithic, and dependency-light.
-
-### docs/policy/development.md
-
-**Audience:** developers, LLM coding agents
-
-Required for projects maintained by humans and LLM coding agents.

-
-If documentation and code disagree, fix the documentation and/or open a roadmap item; do not leave aspirational behavior in current-behavior docs.
-
-Documentation is complete only when it matches the current code.
-
-## Documentation Change Checklist
-
-Before merging documentation changes, verify:
-
-- README is concise and orientation-focused.
-- `docs/policy/architecture.md` describes development principles.
-- Future work appears only under `docs/roadmap/`.
-- User-facing docs avoid unnecessary internals.
-- Developer-facing docs preserve boundaries and invariants.
-- Config examples match the schema.
-- CLI examples match real commands and flags.
-- Defaults appear in the canonical config reference.
-- No secrets or private data are included.
-- Links are accurate.
+### One Canonical Documentation Owner
+
+Each authoritative fact belongs in one canonical document or documentation
+area. A non-owning document may give a short, stable summary for orientation,
+but it must link to the canonical owner instead of maintaining a second
+definition.
+
+Volatile details include commands, flags, configuration fields and defaults,
+report and module IDs, schemas, file names, paths, status and exit behavior,
+retry behavior, and runtime guarantees. If readers could reasonably treat a
+statement as a contract, its exact documentation belongs with the owner named
+in this policy.
+
+Executable sources of truth and documentation owners serve different purposes.
+Code, schemas, and embedded assets determine runtime behavior. The canonical
+document owns the corresponding explanation or reference for readers. Both may
+necessarily express the same contract, but other documentation should summarize
+and link rather than create another complete reference. When implementation and
+documentation disagree, verify the intended behavior and update them together.
+
+### Current State, Decisions, And Future Work
+
+Outside `docs/roadmap/`, documentation describes implemented behavior only.
+Partial features may be described only to their implemented boundary.
+
+An accepted architecture decision may describe an approved direction before it
+is implemented, but acceptance is not evidence that the behavior exists.
+Current-state documents change when the implementation lands. Temporary
+roadmaps own future work, sequencing, and implementation status; they do not
+replace durable policies, decisions, or current contracts.
+
+### Audience And Detail
+
+Write for the document's stated audience and include only the detail needed for
+its owned topic. User and operator documentation should not expose incidental
+implementation detail. Developer documentation should link to user-facing and
+external contracts instead of restating them.
+
+### Links
+
+Use descriptive link text and repository-relative links for repository
+documents. Link to the canonical owner rather than to a duplicate summary.
+Check every added or changed link, and repair or remove links when their target
+moves or is retired.
+
+### Examples And Code Fences
+
+Complete copyable files belong in `examples/` when maintained examples exist.
+Documentation may use the smallest illustrative snippet needed for its owned
+topic, but should link to a maintained example instead of embedding a second
+complete copy.
+
+Examples must be valid, secret-free, and tested where practical. Commands,
+flags, configuration, imports, and Go snippets must match implemented behavior.
+Use a language tag on fenced code blocks, and identify fragments that are
+illustrative rather than directly runnable.
+
+### Security And Privacy
+
+Documentation and examples must not contain real credentials, private keys,
+private environment dumps, sensitive source material, or private
+infrastructure details unless intentionally public. Document secret-handling
+mechanisms, not secret values.

+| Complete copyable artifacts | `examples/` | Maintained configuration and other files intended to be copied or run. | Field-by-field reference, command reference, and prose explanation. |
+
+Conditional owners do not require placeholder files or directories. If
+Weatherreporter introduces a new public API, consumer interface, release
+process, or other durable documentation responsibility, update this policy to
+assign its canonical owner when that responsibility is introduced.
+
+## Boundary Rules
+
+### Orientation, Architecture, And Internals
+
+The README owns product orientation. The development policy routes contributors
+and owns the concise current package inventory. Architecture owns normative
+structure and invariants. Focused internal documents own implementation
+behavior. These documents may link to one another but must not maintain
+parallel package or behavior references.
+
+### Commands, Configuration, And Operations
+
+CLI documentation answers how to invoke Weatherreporter and what its command
+interface does. Configuration documentation answers what settings mean.
+Operations answers how to handle operator-owned outputs and runtime failures,
+including diagnosis, explicit debug capture, and safe legacy cleanup.
+
+When a workflow crosses these topics, place the complete procedure with the
+document that owns the task and link to the other contracts. Do not duplicate
+complete flag, field, or path references to make a workflow self-contained.
+
+### Templates, Integrations, And Implementation
+
+Template documentation defines the maintainer-facing rendering surface.
+Integration documentation defines externally observable shapes, logical paths,
+protocols, and compatibility behavior. Internal documentation explains how
+Weatherreporter produces, transforms, or consumes those contracts.
+
+Internal documents may name a command, field, template value, path, or protocol
+to identify a dependency, but must link to its canonical documentation for the
+complete definition.
+
+### Release Procedure And Release Notes
+
+The release procedure owns how a maintainer prepares, publishes, verifies, and
+recovers from a Weatherreporter release. Release notes under `docs/releases/`
+own the concise historical summary for one version and are the checked-in
+source for its generated Gitea release body.
+
+Release notes are not current-state reference documents. They may summarize
+what changed and link to durable documentation, but they must not become a
+second command, configuration, operations, integration, architecture, or
+internal reference. Correct the applicable canonical owner in the same change
+when a release changes an implemented contract.
+
+The release note at a published tag and the Gitea release generated from it are
+historical records. Later corrections on `main` do not rewrite that published
+record. Material release errors require the failure handling defined by the
+release procedure rather than moving a published tag or overwriting its
+release.
+
+### Executable Authority
+
+CLI parsing and help generation are the executable authority for accepted
+commands and flags. Configuration structs, defaults, loading, and validation
+are the executable authority for configuration behavior. Schemas and embedded
+assets are the executable authority for validated formats and template
+execution. Tests protect selected contracts and invariants but do not become a
+second documentation reference merely by asserting them.
+
+Canonical documentation must be checked against these authorities whenever the
+corresponding behavior changes.
+
+### Security Topics
+
+This policy owns what documentation and examples may contain. Architecture owns
+application security boundaries and invariants. Configuration owns
+credential-supply mechanisms. Operations owns permissions and handling of
+sensitive runtime artifacts. Integration documents own consumer-visible
+security contracts. Internal documents own implementation mechanisms only.
+
+## Architecture Decision Records
+
+Use sequentially numbered ADR filenames such as
+`0001-record-architecture-decisions.md`. Follow the lightweight Nygard format:
+
+1. title;
+2. status;
+3. date;
+4. context;
+5. decision;
+6. alternatives considered;
+7. consequences.
+
+Use one of these statuses:
+
+- **Proposed:** the decision is under consideration and may change;
+- **Accepted:** the decision is approved, whether or not implementation is
+  complete;
+- **Rejected:** the proposed decision was considered and not adopted;
+- **Superseded:** a later accepted ADR replaces the accepted decision.
+
+A proposed ADR transitions to Accepted or Rejected. An Accepted ADR transitions
+to Superseded only when a later Accepted ADR replaces it. An ADR may be created
+as Accepted when the decision has already been made.
+
+Treat the decision content of an Accepted ADR as immutable. A changed decision
+requires a later ADR rather than a rewrite of the accepted record. A Superseded
+ADR must link to its replacement, and the replacement must link back. Rejected
+architectural alternatives belong in the ADR; rejected feature ideas belong in
+a roadmap when they need to be retained.
+
+## Document Lifecycle
+
+Create durable current-state documentation with the implementation it
+describes. Update its canonical owner in the same change when behavior changes.
+If ownership moves, remove the old definition and leave a link where navigation
+remains useful.
+
+Roadmaps are temporary coordination documents. When their work is complete,
+record completion, move any still-useful decisions or contracts to their
+durable owners, update incoming links, and archive or remove the roadmap
+according to repository practice. Do not preserve completed roadmaps as a
+second current-state reference.
+
+Release notes are durable historical summaries rather than temporary roadmaps.
+Keep them concise, retain them after publication, and keep current contracts in
+their canonical owners.
+
+Before completing documentation work:
+
+- verify affected behavior and examples;
+- check commands, flags, fields, defaults, schemas, paths, and identifiers
+  against their implementation;
+- keep unimplemented behavior in a roadmap, subject to the ADR exception;
+- validate links and fenced examples;
+- confirm non-owning documents summarize and link rather than redefine;
+- remove stale or unsupported claims; and
+- confirm that no secrets or sensitive private data were added.

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

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

+# Weatherreporter v0.10.0
+
+Weatherreporter `v0.10.0` makes report execution stateless, adds stable
+weather-specific Promptkit profiles, and turns every successful generation
+into one atomic operator-owned Markdown output.
+
+## Summary
+
+- Ordinary generation no longer creates or depends on a managed workspace,
+  historical run artifacts, metadata, receipts, or prior snapshots.
+- `generate` and `run` now publish directly to operator-selected paths, with
+  useful current-directory defaults when output flags are omitted.
+- Local Recent Changes comparison and the historical `inspect` command family
+  have been removed.
+- Promptkit `v0.5.0` and three embedded logical profiles provide a stable model
+  ladder with complete file- or directory-based overrides.
+- Prompt input and generated-text contracts have been tightened, and output,
+  cancellation, batch preflight, notification, and partial-failure behavior
+  have focused offline coverage.
+
+## Compatibility
+
+This pre-`v1` minor release intentionally breaks CLI, configuration,
+prompt-input, action-summary, and workspace contracts from `v0.9.0`.
+
+- The `workspace:` and `recent_change:` configuration sections are no longer
+  supported. Strict configuration loading rejects them.
+- The `inspect reports`, `inspect metadata`, `inspect modules`,
+  `inspect data-package`, `inspect prior`, and `inspect sources` commands have
+  been removed. Weatherreporter no longer reads V1 or V2 run metadata or other
+  historical workspace artifacts.
+- Every successful `generate` writes exactly one Markdown file. Without
+  `--out`, Daily writes `daily-YYYY-MM-DD.md` and Today, Tomorrow, and Hourly
+  write `today.md`, `tomorrow.md`, and `hourly.md` in the invocation's current
+  directory. `--out` selects that file rather than creating an extra copy of a
+  separately managed report.
+- `run` writes selected outputs beneath the current directory unless
+  `--out-dir` selects another directory. Successful items remain available
+  when another batch item fails.
+- Action summaries no longer expose managed report, metadata, snapshot, data
+  package, prompt preparation, prompt execution, generated-text, render-context,
+  or notification-receipt paths. They retain the final `outputPath`, optional
+  `llmDebugPath`, safe effective profile/backend/model details, validation,
+  warnings, notification status, and safe errors.
+- Batch report items no longer contain per-report notification fields. Batch
+  notification is represented once at the top level. The `total`, `succeeded`,
+  and `failed` counters describe reports only, so notification failure can
+  produce a failed action while `failed` remains `0`.
+- The prompt data package advances from `weatherreporter.data_package.v3` to
+  `weatherreporter.data_package.v4` and removes `recent_changes`. All four
+  embedded prompts advance from `1.1.0` to `2.0.0`.
+- Generated-text schemas now require string-valued `precipitation_timing`; the
+  model returns an empty string when there is no timing text. The unused
+  `confidence` field has been removed and is rejected as an unknown field.
+
+Existing operator-owned Markdown files remain valid. Existing workspace trees
+are ignored rather than migrated or deleted. Distributor continues to receive
+the completed Markdown report, but its source is now the selected operator
+output rather than a managed report copy.
+
+## Upgrade
+
+Before replacing `v0.9.0`:
+
+1. Remove `workspace:` and `recent_change:` from configuration files.
+2. Give scheduled commands a predictable working directory or explicit
+   `--out` or `--out-dir` destination. Confirm that these selected files may be
+   atomically replaced on later successful runs.
+3. Remove historical `inspect` invocations and update action-summary consumers
+   to use `outputPath` and the remaining active-workflow fields.
+4. Decide whether old workspace contents have any external retention value.
+   Weatherreporter no longer reads them; after review, they may be removed
+   manually using the narrowly scoped procedure in the operations guide.
+5. Review Promptkit profile selection and credentials. Hourly defaults to
+   `weather-light`; Daily, Today, and Tomorrow default to `weather-balanced`.
+   A configured `promptkit.profile` still overrides every report in one action.
+
+The embedded logical profiles are:
+
+| Profile | OpenRouter model | Default use |
+| --- | --- | --- |
+| `weather-light` | `deepseek/deepseek-v4-flash` | Hourly |
+| `weather-balanced` | `~google/gemini-flash-latest` | Daily, Today, Tomorrow |
+| `weather-deep` | `~anthropic/claude-sonnet-latest` | Explicit selection |
+
+Override a complete same-ID definition through `promptkit.profile_file` or
+`promptkit.profile_dir` to use different models or a local OpenAI-compatible
+endpoint. Definitions are replaced rather than field-merged, and a malformed
+matching override fails instead of silently falling back.
+
+See the [CLI reference](../cli.md), [configuration
+reference](../config.md), [operations guide](../operations.md), and [Promptkit
+integration](../integrations/promptkit.md) for the exact current contracts.
+
+## Changes
+
+### Stateless Execution And Operator-Owned Outputs
+
+- Removed local forecast-change comparison, prior-snapshot selection, durable
+  module and prompt artifacts, managed reports, metadata compatibility, run
+  discovery, notification receipts, and the complete `internal/state`
+  subsystem.
+- Added an Accepted architecture decision recording the stateless
+  transformation pipeline and operator-owned output boundary.
+- Kept weather, facts, modules, prompt input, generated text, and render context
+  in memory during ordinary execution.
+- Made output publication atomic and ensured cancellation or deadline expiry
+  observed before publication leaves an existing destination unchanged.
+- Added complete batch-destination preflight before the first report prompt,
+  so a structural collision cannot leave an unreported partial batch.
+- Preserved successful outputs after report or Distributor failure. Batch
+  notification runs only after every selected report succeeds.
+
+### Promptkit Profiles And Prompt Contracts
+
+- Upgraded Promptkit from `v0.4.0` to `v0.5.0`.
+- Added embedded `weather-light`, `weather-balanced`, and `weather-deep`
+  profiles and mapped each exact prompt to its logical default.
+- Added embedded-profile fallback after configured `profile_file` or
+  `profile_dir` lookup, allowing operators to replace a logical profile without
+  changing report definitions.
+- Added a maintained local-endpoint example for replacing `weather-light`.
+- Advanced the four prompt definitions to `2.0.0` and the curated data package
+  to v4 after removing Recent Changes.
+- Required `precipitation_timing`, normalized whitespace-only timing to an
+  empty string, and removed the unused confidence value.
+
+### CLI, Reliability, Documentation, And Testing
+
+- Simplified action summaries to active workflow identity, output, model,
+  validation, warning, debug, notification, and safe error information.
+- Made batch counters report-only while retaining failed action status and
+  non-zero exit behavior for batch notification failure.
+- Kept prompt and profile inspection ahead of weather collection and validated
+  every batch candidate before collecting once.
+- Replaced state-oriented workflow fixtures with focused generation, batch,
+  output, cancellation, profile-resolution, Distributor, and CLI coverage.
+- Reconciled user, operator, integration, internal, policy, and ADR
+  documentation around the implemented stateless architecture and removed
+  completed temporary roadmaps.

+# Weatherreporter v0.10.1
+
+This release repairs release validation after the `v0.10.0` pipeline failed in
+its privileged build container. Application behavior is unchanged from
+`v0.10.0`.
+
+## Summary
+
+The unreadable-secret configuration test now verifies that its process is
+actually subject to file permission bits before asserting that a mode-`000`
+file cannot be read. This keeps the test meaningful for ordinary users while
+allowing the release suite to run correctly in privileged containers.
+
+## Compatibility
+
+This patch release makes no changes to Weatherreporter's CLI, configuration,
+report output, integrations, prompts, profiles, or operating behavior. It is
+fully compatible with `v0.10.0`.
+
+## Upgrade
+
+No special operator action is required. Use `v0.10.1` in place of `v0.10.0`;
+the `v0.10.0` tag remains immutable, but its failed pipeline did not publish
+release binaries.
+
+## Changes
+
+- Made the unreadable-secret test capability-aware when the test process can
+  bypass filesystem permission bits.
+- Preserved the production contract that genuinely unreadable secret files
+  fail configuration loading.
+- Restored portable release validation in Woodpecker's privileged Go
+  container.

+# Weatherreporter v0.11.0
+
+This release adds a configurable default publication directory for generated
+weather reports.
+
+## Summary
+
+Operators can now set `output.directory` once for both individual reports and
+scheduled batches. Explicit `--out` and `--out-dir` destinations continue to
+take precedence, while installations that omit the setting retain the existing
+current-directory behavior.
+
+## Compatibility
+
+This release is additive and compatible with `v0.10.1`. Existing configuration
+files, commands, report filenames, Promptkit behavior, and Distributor
+notification behavior remain valid and unchanged.
+
+## Upgrade
+
+No special action is required. To use the new default destination, configure
+`output.directory` as described in the [configuration
+reference](../config.md). Existing deployments may continue using the current
+working directory or explicit CLI output flags.
+
+## Changes
+
+- Added strict configuration loading and validation for the optional
+  `output.directory` field.
+- Applied the configured directory consistently to `generate` and `run`, with
+  explicit CLI destinations retaining highest precedence.
+- Preserved relative-path handling, absolute result paths, atomic publication,
+  cancellation safety, and Distributor notification ordering.
+- Strengthened output preflight so existing non-directory paths, uninspectable
+  paths, and dangling symlink components fail before expensive report work.
+- Updated the [CLI reference](../cli.md) and [operations
+  guide](../operations.md) for the new destination-selection behavior.

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

 # Future Roadmap
 
-This roadmap contains project work that is not implemented. Current behavior is
-documented outside `docs/roadmap/`.
+This roadmap contains future work only. Each section identifies its planning
+status; current behavior is documented outside `docs/roadmap/`.
+
+## Upstream Forecast Change Product
+
+Status: Proposed upstream feature request; unimplemented.
+
+Weatherreporter's local Recent Changes feature was removed by the accepted
+[stateless execution decision](../adr/0001-stateless-execution.md). Forecast
+version history and comparison are better owned by the Weather API, where the
+underlying forecast issuances can be retained and compared consistently for
+all consumers.
+
+A future Weather API feature should expose a structured change product with:
+
+- explicit current and baseline forecast issuance timestamps or identifiers;
+- documented baseline selection, such as a requested comparison timestamp,
+  preceding issuance, or fixed rolling period;
+- location, timezone, and half-open valid-period identity;
+- typed changed values with previous and current values and units;
+- stable change categories for temperature, precipitation probability and
+  timing, wind gusts, alerts, and aggregate hazards;
+- an API-owned significance classification or enough structured information
+  for a stateless consumer to apply a documented presentation threshold; and
+- deterministic ordering, missing-baseline behavior, and source metadata.
+
+The API should compare forecast versions, not track a Weatherreporter client's
+"previous run." It should not require consumer identity, mutable cursors, or
+Weatherreporter-managed history. A missing baseline should be a normal empty
+result rather than an error.
+
+Once a stable upstream contract exists, a separate Weatherreporter roadmap may
+reintroduce change commentary by collecting that product and mapping it into a
+curated prompt-facing module. There must be no local snapshot fallback. The
+ordinary Weatherreporter process must remain stateless, and the upstream
+feature should have deterministic fixtures before adoption.
 
 ## Automatic Storm Monitoring
 
-Manual Storm Report generation is implemented through
-`weatherreporter generate storm --start TIME --end TIME`. Automatic storm-event
-evaluation remains deferred.
+Status: Proposed and unimplemented.

+# LLM Profile Comparison Roadmap
+
+Status: Accepted; unimplemented.
+
+## Purpose
+
+Prompt development currently requires separate Weatherreporter invocations to
+compare several LLM profiles. Those invocations may collect different weather
+snapshots or rebuild inputs at different times, making model output harder to
+compare and slowing prompt iteration.
+
+Weatherreporter should provide a first-class `compare` command that resolves
+one report, prepares one exact data package, executes the same prompt and data
+package concurrently through several explicitly selected Promptkit profiles,
+and publishes a self-contained local comparison bundle.
+
+An illustrative invocation is:
+
+```sh
+weatherreporter compare daily \
+  --date 2026-08-24 \
+  --profile weather-light \
+  --profile weather-balanced \
+  --profile weather-deep
+```
+
+This is a prompt-development workflow, not an automated model evaluator. Its
+output gives a maintainer consistent evidence for human comparison without
+assigning scores or selecting a winner.
+
+## Prerequisite
+
+Configurable output directories are implemented. Profile comparison must reuse
+the current [configuration reference](../config.md) and [operations
+guide](../operations.md) rather than introduce a second destination policy.
+
+## User Intent
+
+The command is intended for deliberate evaluation of multiple profiles,
+including sets of eight to twelve candidate models. Concurrency is part of the
+feature, not a future optimization. Promptkit should retain ownership of
+backend-specific capacity, while Weatherreporter owns comparison-wide
+coordination, cancellation, deterministic results, and artifact publication.
+
+Every profile must receive byte-for-byte identical prompt input. Weather data,
+derived facts, modules, prompt metadata, and serialized YAML must not be
+recollected or rebuilt separately for individual profiles.
+
+Comparison bundles are explicitly requested, operator-owned development
+outputs. They are not Weatherreporter state, are never read implicitly by a
+later run, and do not weaken the ordinary stateless execution model.
+
+## Command Contract
+
+The command form is:
+
+```text
+weatherreporter compare REPORT [options]
+```
+
+`REPORT` accepts the implemented generated-text reports: `daily`, `today`,
+`tomorrow`, and `hourly`. Report-date behavior matches `generate`: `daily`
+requires `--date`, `today` may accept an explicit date or use the current local
+date, and the remaining report types retain their existing period policies.
+
+The command accepts the applicable common generation options, including
+`--config`, `--units`, `--tz`, `--date`, `--llm-debug-dir`, and `--quiet`, plus:
+
+- repeatable `--profile PROFILE_ID` selections;
+- `--out-dir PATH` for the exact comparison-bundle directory; and
+- `--replace` to authorize guarded replacement of a recognized existing
+  comparison bundle.
+
+At least two distinct, nonblank profile IDs are required. Their command-line
+order is significant and is preserved in filenames, summaries, and
+`comparison.json`. Duplicate profile IDs are rejected rather than silently
+deduplicated or executed twice.
+
+Profiles are always explicit for this command. `promptkit.profile` does not add
+or replace a comparison selection, but all other effective Promptkit settings,
+profile-source precedence, local backend configuration, credential lookup, and
+profile overrides remain in force.
+
+The initial feature has no Weatherreporter-specific concurrency flag or
+artificial profile-count ceiling. The explicit profile list bounds the
+comparison, and Promptkit owns capacity enforcement for each selected backend.
+
+## Preparation And Execution Invariants
+
+A comparison has this logical lifecycle:
+
+1. Parse and validate the report, date, profile list, configuration, output
+   destination, and replacement authorization.
+2. Resolve the report definition, valid period, prompt identity, and default
+   output name once.
+3. Inspect the exact prompt once and preflight every selected profile,
+   including its effective backend, model, and required credential
+   availability, before weather collection.
+4. Collect weather data exactly once.
+5. Build collected and derived facts, the module snapshot, briefing metadata,
+   and the prompt data package exactly once.
+6. Marshal the data package to one immutable YAML byte sequence exactly once.
+7. Execute the exact prompt version concurrently for every selected profile,
+   passing the same immutable YAML bytes to every execution.
+8. Validate and render each profile result independently from the shared
+   deterministic inputs.
+9. Assemble results in requested-profile order and publish one coherent
+   comparison bundle.
+
+This lifecycle describes the required end-state behavior rather than an
+implementation-stage sequence.
+
+No profile execution may cause recollection, report re-resolution, module
+rebuilding, or data-package remarshalling. Prompt execution may perform
+Promptkit-owned validation or repair behavior, but Weatherreporter does not
+retry a failed comparison execution independently.
+
+## Concurrency And Cancellation
+
+Weatherreporter starts one execution for each preflighted profile and permits
+them to run concurrently through one shared, concurrency-safe Promptkit
+executor. Promptkit's engine-local backend pools remain authoritative for
+backend concurrency and waiting capacity. Profiles routed to a limited local
+backend therefore respect its configured limit, while profiles routed to
+other backends may proceed independently.
+
+Weatherreporter must not add a second semaphore that obscures or overrides
+Promptkit's backend policy. It must safely coordinate goroutine lifecycles,
+result collection, debug callbacks, and output assembly without data races.
+
+One profile failure does not cancel its peers. Provider, capacity, validation,
+and rendering failures are recorded for that profile while other executions
+continue. Cancellation or deadline expiration of the comparison command is
+propagated to every outstanding execution, prevents new publication, and is
+joined without leaking goroutines.
+
+Completion order must not affect filenames, manifest order, CLI summaries, or
+error aggregation. Those outputs always follow the original `--profile`
+order.
+
+## Output Destination
+
+Without `--out-dir`, Weatherreporter derives a comparison directory from the
+resolved report's existing default Markdown filename by removing `.md` and
+prefixing `comparison-`:
+
+| Report output | Comparison directory |
+| --- | --- |
+| `today.md` | `comparison-today/` |
+| `tomorrow.md` | `comparison-tomorrow/` |
+| `hourly.md` | `comparison-hourly/` |
+| `daily-2026-08-24.md` | `comparison-daily-2026-08-24/` |
+
+The derived directory is created beneath `output.directory` when configured,
+or beneath the present working directory otherwise. An explicit `--out-dir`
+is the exact bundle directory, resolves relative to the present working
+directory when necessary, and overrides `output.directory` completely.
+
+All destination selection and validation completes before weather collection.
+The resolved comparison directory is returned in the command's structured
+result.
+
+## Comparison Bundle
+
+A successful three-profile comparison has a flat layout:
+
+```text
+comparison-daily-2026-08-24/
+├── comparison.json
+├── data-package.yml
+├── 01-weather-light.md
+├── 02-weather-balanced.md
+└── 03-weather-deep.md
+```
+
+`data-package.yml` contains the exact YAML bytes passed to every Promptkit
+execution. It is written once and its SHA-256 digest is recorded in the
+manifest.
+
+Each report filename begins with its one-based, zero-padded selection position
+and a filesystem-safe representation of the requested logical profile ID. The
+safe representation must not permit absolute paths, traversal, separators, or
+control characters. The manifest retains the exact case-sensitive profile ID,
+so filename normalization never becomes the authority for profile identity.
+
+`comparison.json` is the authoritative index for the bundle. It uses an
+explicit schema version and records safe comparison information including:
+
+- comparison identity and start and finish timestamps;
+- report ID, resolved valid period, and effective timezone;
+- prompt ID, version, and inspected prompt hash;
+- the relative data-package filename and SHA-256 digest;
+- total, succeeded, and failed profile counts; and
+- one ordered result per requested profile containing the exact profile ID,
+  resolved backend and model, relative report filename when present,
+  execution and validation status, and safe error information when failed.
+
+The manifest and normal command summary must not contain credentials, provider
+request bodies, raw model output, rendered prompts, schemas, provider
+endpoints, or other content-rich diagnostics. The explicit data package and
+generated reports contain the development material the user requested and
+must be handled as operator-owned potentially sensitive output.
+
+## Failure And Publication Policy
+
+Failure before concurrent execution, including invalid profiles, missing
+credentials, collection failure, preparation failure, or unsafe destination,
+publishes no comparison bundle and performs no model calls where the failure
+is discoverable during preflight.
+
+After execution begins, Weatherreporter waits for every non-cancelled profile.
+If one or more profiles fail, it still publishes a coherent partial bundle
+containing `data-package.yml`, every successfully rendered report, and a
+manifest describing all successes and failures. It then returns a non-zero
+exit status. A failed profile has no report file unless a future contract
+explicitly introduces a separately named diagnostic artifact.
+
+Bundle contents are staged outside the destination and published only after
+the manifest is complete. Ordinary publication accepts only an absent or empty
+target directory. A nonempty existing directory fails without modification
+unless `--replace` is present.
+
+`--replace` may replace only the exact resolved target and must reject broad or
+unsafe targets such as a filesystem root, the present working directory, a
+symlink, or an unrecognized nonempty directory. A recognized prior bundle must
+contain a valid Weatherreporter comparison manifest. Replacement publishes the
+new complete or coherent partial bundle as a unit, prevents stale reports from
+the prior comparison from surviving, and preserves or restores the prior
+bundle if the final replacement operation fails.
+
+An interrupted or cancelled comparison does not replace an existing bundle.
+Temporary staging artifacts are cleaned up on ordinary failure and
+cancellation without scanning or modifying unrelated directories.
+
+## Prompt Debugging
+
+The existing `--llm-debug-dir` mechanism remains available. Concurrent
+comparison executions require distinct, deterministic debug identities that
+include the comparison and exact profile selection so callbacks cannot collide
+or overwrite another profile's artifacts.
+
+Debug writing must be concurrency-safe and retain the existing permission,
+redaction, explicit-opt-in, and path-containment guarantees. Debug artifacts
+remain separate from the comparison bundle; the bundle does not implicitly
+enable full Promptkit diagnostics.
+
+## Notification Policy
+
+Profile comparisons never invoke Distributor notification, even when
+notification is enabled in the effective configuration. Comparison reports
+are local development artifacts rather than ordinary report publications.
+
+Adding comparison publication or upload behavior would require a separate
+accepted feature scope and explicit operator authorization.
+
+## Architectural End State
+
+Application orchestration exposes a reusable prepared-report boundary that
+contains the resolved report, shared collected and derived facts, module
+snapshot, briefing metadata, generated-text handler, render inputs, and exact
+serialized data package. That boundary is immutable during concurrent profile
+execution.
+
+Ordinary `generate` behavior continues to prepare once and execute once.
+`compare` prepares once and executes many without duplicating the generation
+workflow or calling `GenerateDetailed` in a loop. Shared preparation,
+profile-specific Promptkit execution, structured-output validation, rendering,
+and artifact publication remain distinct responsibilities.
+
+The Promptkit adapter remains the only owner of dependency-specific types and
+engine calls. The CLI owns parsing and user-facing summaries. The configuration
+package owns configuration. Application orchestration owns comparison order,
+concurrency lifecycle, failure aggregation, and bundle publication. Domain,
+prompt-input, generated-text, and template packages retain their existing
+deterministic contracts.
+
+## Scope
+
+The completed feature includes:
+
+- the `compare` CLI command for every implemented generated-text report;
+- repeatable explicit profile selection and validation;
+- configured and CLI output-directory integration after the prerequisite
+  feature lands;
+- one-time report resolution, collection, deterministic preparation, and YAML
+  serialization;
+- concurrent execution through one Promptkit executor with backend capacity
+  respected;
+- independent validation and rendering with deterministic ordered results;
+- the flat, versioned comparison-bundle contract;
+- safe filename derivation and data-package hashing;
+- coherent partial-result publication and non-zero failure behavior;
+- guarded whole-bundle replacement through `--replace`;
+- comparison-aware, concurrency-safe optional prompt debugging;
+- explicit suppression of Distributor notification;
+- structured normal and quiet-mode CLI behavior consistent with existing
+  commands;
+- focused race-safe tests across configuration, CLI, application,
+  Promptkit-adapter, rendering, and filesystem boundaries; and
+- updates to every affected canonical user, operator, architecture,
+  integration, and internal document.
+
+## Compatibility
+
+The feature is additive. Existing `generate` and `run` commands, report
+definitions, profile defaults, configuration, output filenames, notification
+behavior, and exit contracts remain unchanged.
+
+The comparison manifest and bundle layout begin as versioned contracts. They
+do not become inputs accepted by Weatherreporter, and no backward-compatible
+replay or long-term archive guarantee is implied beyond identifying the schema
+used to interpret a produced bundle.
+
+## Testing Expectations
+
+Tests should provide durable coverage for:
+
+- report and date parsing consistent with `generate`;
+- rejection of fewer than two profiles, blanks, and duplicates;
+- inspection of the exact prompt and every profile before collection;
+- no collection or model execution after a preflight failure;
+- exactly one weather collection and one preparation for several profiles;
+- byte-for-byte identical data-package input in every execution;
+- observable concurrent execution through a concurrency-safe fake executor;
+- respect for Promptkit-owned backend capacity in an assembled adapter test
+  where that integration adds distinct confidence;
+- deterministic filenames, manifest order, summaries, and errors under varied
+  completion order;
+- continuation and coherent partial publication after one profile fails;
+- cancellation propagation, goroutine completion, and preservation of an
+  existing destination;
+- destination precedence and each derived default directory;
+- safe filename handling for unusual valid profile IDs;
+- absent, empty, occupied, symlinked, unsafe, recognized, and unrecognized
+  replacement targets;
+- removal of stale prior report files during authorized whole-bundle
+  replacement;
+- exact package digest and manifest/result consistency;
+- concurrency-safe, non-colliding opt-in debug artifacts; and
+- absence of Distributor calls for complete and partial comparisons.
+
+Concurrency and replacement behavior require race-enabled and consequential
+failure-path coverage. Tests must remain deterministic, offline, credential
+free, and independent of real Promptkit providers or machine-specific paths.
+
+## Documentation End State
+
+Once implemented, the [CLI reference](../cli.md) owns command syntax, flags,
+summary, and exit behavior. The [operations guide](../operations.md) owns the
+bundle lifecycle, replacement procedure, sensitivity guidance, and practical
+prompt-comparison workflow. The [architecture policy](../policy/architecture.md)
+owns the statelessness, concurrency, notification, and publication invariants.
+
+The [Promptkit integration guide](../integrations/promptkit.md) should describe
+the consumer-visible multi-profile execution boundary without duplicating
+Promptkit's backend-capacity reference. App orchestration, prompt input,
+generated text, prompt debugging, and any new bundle implementation details
+belong in focused documents under `docs/internal/`.
+
+Current-state documentation must not describe profile comparison as available
+until the implementation lands.
+
+## Non-Goals
+
+This roadmap does not introduce:
+
+- automatic model scoring, ranking, recommendation, or winner selection;
+- semantic or textual diff generation between reports;
+- repeated sampling of one profile or statistical evaluation;
+- prompt or profile editing through Weatherreporter;
+- replaying a saved data package as command input;
+- comparing several report types in one command;
+- Weatherreporter-owned backend concurrency or queue configuration;
+- automatic retries beyond Promptkit's existing execution contract;
+- Distributor upload or other external publication;
+- comparison history, indexing, retention, cleanup schedules, or implicit
+  discovery of prior bundles; or
+- changes to ordinary report content or normal generation behavior.
+
+Any later automated evaluation, replay, sampling, or publication feature
+requires a separate accepted roadmap.
+
+## Completion Criteria
+
+The feature is complete when a maintainer can select several Promptkit
+profiles, have them execute concurrently against one exact prepared report
+package, and receive a safe, flat, deterministic comparison bundle whose
+manifest accurately describes every success and failure. Configured and
+explicit destinations must follow the accepted output policy, replacement must
+never mix or silently destroy unrelated contents, cancellation and partial
+failure must be race-safe, ordinary notification must remain disabled, and all
+affected canonical documentation must describe the implemented behavior.
+
+## Open Questions
+
+None. The scope, prerequisites, user intent, and target behavior required for a
+future staged implementation plan are defined above.

+# Report Templates
+
+This guide is for maintainers editing Weatherreporter's embedded Markdown
+templates. Templates format already validated report inputs; they do not select
+sources, derive weather facts, or validate generated prose. For those details,
+see [Generated Text internals](internal/generatedtext.md) and [Report Template
+internals](internal/reporttemplate.md).
+
+## Template Assets
+
+Only the generated-text reports use repository-native Markdown templates.
+Each report has one matching template ID, generated-text schema ID, and prompt
+source:
+
+| Report | Template | Schema | Prompt ID and source |
+| --- | --- | --- | --- |
+| Daily | `templates/daily.md.tmpl` (`daily`) | `daily` | `weather.daily_generated_text`; `internal/promptassets/assets/prompts/daily/` |
+| Today | `templates/today.md.tmpl` (`today`) | `today` | `weather.today_generated_text`; `internal/promptassets/assets/prompts/today/` |
+| Tomorrow | `templates/tomorrow.md.tmpl` (`tomorrow`) | `tomorrow` | `weather.tomorrow_generated_text`; `internal/promptassets/assets/prompts/tomorrow/` |
+| Hourly | `templates/hourly.md.tmpl` (`hourly`) | `hourly` | `weather.hourly_generated_text`; `internal/promptassets/assets/prompts/hourly/` |
+
+The matching schemas and Promptkit definitions are embedded by
+`internal/promptassets`. The generated-text catalog pairs each schema ID with
+its template ID; keep the matching prompt definition aligned with that pair.
+
+Shared partials are under `internal/reporttemplate/templates/partials/`:
+
+| Partial | Used by |
+| --- | --- |
+| `alert_digest.md.tmpl` | Daily, Today, Tomorrow, and Hourly |
+| `precipitation_timing.md.tmpl` | Daily, Today, Tomorrow, and Hourly |
+| `daypart_forecast.md.tmpl` | Daily and Tomorrow |
+| `today_daypart_forecast.md.tmpl` | Today |
+
+All shared partials are parsed whenever any top-level template is rendered. A
+syntax error in a partial can therefore prevent every generated-text report
+from rendering.
+
+## Editing Rules
+
+- Use Go `text/template` syntax and keep changes to Markdown structure,
+  ordering, and display conditions.
+- Templates use `missingkey=error`; reference only documented fields and guard
+  optional module pointers with `with` or `if`.
+- Prefer `.Modules` for deterministic display values. Do not add weather
+  calculations, source selection, or prompt-input shaping to a template.
+- Keep generated prose in `.GeneratedText`; do not restate deterministic facts
+  in generated prose merely to compensate for a template change.
+- When changing the generated-prose contract, update the matching prompt,
+  schema, validator, render context, and template together. The validation and
+  catalog rules are owned by [Generated Text internals](internal/generatedtext.md).
+- Use `.Modules.Dayparts` for ordered daypart output. Do not range over
+  `.Modules.DerivedDaypartSummaries`, which is a map.
+
+Minimal optional-value pattern:
+
+```gotemplate
+{{ with .Modules.CurrentConditions }}
+Currently, it is {{ with .TemperatureF }}{{ . }}°F{{ end }}.
+{{ else }}
+Current conditions are unavailable.
+{{ end }}
+```
+
+Minimal list pattern:
+
+```gotemplate
+{{ range .GeneratedText.ForecastDiscussion }}
+{{ . }}
+{{ end }}
+```
+
+## Registered Functions
+
+Templates have these helpers in addition to Go template built-ins:
+
+| Function | Accepts | Returns true when |
+| --- | --- | --- |
+| `hasRelevantAlerts` | an alert-digest value or pointer | its `Relevant` slice is nonempty |
+| `hasEnhancedOrHigherSPCRisk` | an SPC outlook value or pointer | its `RiskDigest` contains an Enhanced, Moderate, or High Risk entry |
+| `isEnhancedOrHigherSPCRisk` | one SPC risk-digest entry | its `LabelText`, or fallback `RiskLabel`, is Enhanced, Moderate, or High Risk |
+
+For example, the alert partial uses the first two functions to decide whether
+to render the section:
+
+```gotemplate
+{{ if hasRelevantAlerts .Modules.AlertDigest }}
+## Alert Digest
+{{ end }}
+```
+
+## Render Context
+
+Every rendered template receives one typed context with these five top-level
+fields:
+
+| Field | Purpose |
+| --- | --- |
+| `.Report` | Display labels and canonical report timing metadata. |
+| `.GeneratedText` | Validated prose supplied by Promptkit. |
+| `.Modules` | Deterministic, typed values prepared for Markdown rendering. |
+| `.Collected` | Normalized upstream facts for advanced use. |
+| `.Derived` | Shared calculated facts for advanced use. |
+
+`.Collected` and `.Derived` are available for an exceptional display need, but
+they are lower-level contracts. Keep reusable weather derivation in Go and use
+the module surface for normal template work.

+
+All contexts provide `.Report.Title`, `.Report.GeneratedAt`,
+`.Report.GeneratedAtLabel`, `.Report.ValidPeriod`, and `.Report.Timezone`.
+
+Hourly additionally provides `.Report.LocationName` and
+`.Report.ValidPeriodLabel`.
+
+Daily, Today, and Tomorrow additionally provide `.Report.ForecastDate`,
+`.Report.ForecastDateLabel`, and `.Report.ForecastDayName`. Their valid-period
+field remains canonical timing data; use the supplied display labels instead
+of formatting timestamps in a template.
+
+### Validated GeneratedText Prose
+
+GeneratedText is prose returned by Promptkit and validated before rendering.
+It is not a source for deterministic weather facts.
+
+| Field | Hourly type | Daily, Today, and Tomorrow type | Notes |
+| --- | --- | --- | --- |
+| `.GeneratedText.Summary` | `string` | `string` | Required. |
+| `.GeneratedText.ForecastDiscussion` | `string` | `[]string` | Required; range over the day-style paragraph slice. |
+| `.GeneratedText.PrecipitationTiming` | `string` | `string` | Required field; an empty string represents no supported prose. The precipitation partial uses nonempty prose only when deterministic windows exist. |
+
+The JSON schema rejects unknown properties and defines the required fields, but
+the schema body and validation behavior are documented in [Generated Text
+internals](internal/generatedtext.md).
+
+### Deterministic Module Values
+
+Module values are deterministic outputs built from collected and derived facts.
+Module pointers can be nil when their source or policy permits omission.
+
+| Module field | Available in |
+| --- | --- |
+| `.Modules.Metadata`, `.Modules.CurrentConditions`, `.Modules.HourlyForecast`, `.Modules.PrecipTiming`, `.Modules.AlertDigest`, `.Modules.SPCConvectiveOutlooks`, `.Modules.AreaForecastDiscussion`, `.Modules.SPCConvectiveDiscussion`, `.Modules.WeatherStory` | All four contexts |
+| `.Modules.DerivedDailySummary`, `.Modules.DerivedDaypartSummaries`, `.Modules.Dayparts` | Daily, Today, Tomorrow |
+| `.Modules.OutdoorWindows`, `.Modules.DailyPlanning` | Daily |
+| `.Modules.TodayPlanning` | Today |
+| `.Modules.TomorrowPlanning` | Tomorrow |
+
+The repository templates currently use the following nested display values.
+They are the preferred surface for comparable edits:
+
+| Area | Values |
+| --- | --- |
+| Current conditions | `.TemperatureF`, `.ConditionText`, `.ConditionTextLower`, `.ApparentTemperatureF`, `.RelativeHumidityPercent`, `.WindDirectionText`, `.WindSpeedMph` |
+| Hourly periods | `.Periods`, `.HourLabel`, `.Name`, `.TemperatureF`, `.TextDescription`, `.TextDescriptionLower`, `.MentionPrecipitation`, `.ProbabilityOfPrecipitationPercent` |
+| Dayparts | `.Dayparts[].Key` and `.Dayparts[].Summary` fields `DisplayName`, `DominantCondition`, `DominantConditionDisplay`, `TemperatureTrend`, `TemperatureStartPhraseF`, `TemperatureEndPhraseF`, `TemperaturePeakPhraseF`, `TemperatureSteadyPhraseF`, `TemperaturePhraseF`, `MentionPrecipitation`, and `MaxPopPercent` |
+| Precipitation timing | `.PrecipitationWindows`, plus each window's `PeriodBegins`, `PeriodBeginsHourLabel`, `PeriodEnds`, `PeriodEndsHourLabel`, `ExpectationPhrase`, `MaxPopPercent`, `MaxPopTime`, and `MaxPopHourLabel` |
+| Alert digest | `.AlertDigest.Relevant` entries' `Event`, `Headline`, `PeriodBegins`, and `PeriodEnds` |
+| SPC risk digest | `.SPCConvectiveOutlooks.RiskDigest` entries' `LabelText`, `RiskLabel`, `PeriodBegins`, and `PeriodEnds` |
+
+Other fields on these typed modules remain available when a template has a
+well-defined display need. Their module contracts and weather derivation belong
+to [Module contract internals](internal/module.md), [Module builder
+internals](internal/briefing.md), and [Forecast derivation
+internals](internal/forecast-derivation.md).
+
+## Validate Changes
+
+Run the focused checks after editing templates, partials, prompts, or schemas:
+
+```sh
+go test ./internal/reporttemplate ./internal/generatedtext ./internal/app
+git diff --check
+```
+
+The render-context and template tests cover Daily, Today, Tomorrow, and Hourly
+contexts. Run the repository-wide test suite before merging a broader change.

-# Weatherreporter Troubleshooting
-
-This guide lists recurring failures with likely causes, diagnostics, and safe
-fixes. See [CLI reference](cli.md), [Configuration reference](config.md), and
-[Operations guide](operations.md) for normal usage.
-
-## `weather_api.base_url is required`
-
-Symptom: a generation command fails before fetching weather data.
-
-Likely cause: no Weather API base URL is configured.
-
-Diagnostic:
-
-```sh
-weatherreporter generate daily --config ./config.yml --date 2026-05-29
-```
-
-Safe fix: add `weather_api.base_url` to the config file, or pass the intended
-config path with `--config`.
-
-Relevant docs: [Configuration reference](config.md).
-
-## `weather_api.base_url must be an absolute URL`
-
-Symptom: config loading fails with a base URL validation error.
-
-Likely cause: `weather_api.base_url` is missing a scheme or host.
-
-Diagnostic: inspect the configured value in the file passed to `--config`.
-
-Safe fix: use an absolute URL such as `https://weather.api.example.com/`.
-
-Relevant docs: [Configuration reference](config.md).
-
-## Invalid Timezone
-
-Symptom: config loading fails with `weather_api.timezone` context, or a CLI
-timezone override fails.
-
-Likely cause: `weather_api.timezone` or `--tz` is not recognized.
-
-Diagnostic:
-
-```sh
-weatherreporter generate daily --tz America/Chicago --date 2026-05-29
-```
-
-Safe fix: use an accepted timezone value, such as an IANA timezone name,
-`Chicago`, `Stl`, a US timezone abbreviation, or a UTC offset.
-
-Relevant docs: [Configuration reference](config.md).
-
-## Storm Command Rejects Time Bounds
-
-Symptom: `generate storm` fails with `requires --start`, `requires --end`, or
-`requires --end after --start`.
-
-Likely cause: the manual event window is missing or invalid.
-
-Diagnostic:
-
-```sh
-weatherreporter generate storm --start 2026-05-29T18:00 --end 2026-05-30T06:00
-```
-
-Safe fix: provide both bounds. Use `YYYY-MM-DDTHH:MM` in the configured
-timezone, or RFC3339 timestamps with explicit offsets.
-
-Relevant docs: [CLI reference](cli.md).
-
-## Weather API Fetch Fails
-
-Symptom: generation fails with `fetch /...`, an HTTP status, or request context.
-
-Likely cause: the configured Weather API endpoint is unreachable, returned a
-non-2xx response, or returned an invalid response envelope.
-
-Diagnostic:
-
-```sh
-weatherreporter generate daily --config ./config.yml --date 2026-05-29
-```
-
-Safe fix: verify `weather_api.base_url`, network access, and the Weather API
-service response. The adapter fetches `/observations`, `/conditions/current`,
-`/forecast/hourly`, `/forecast/narrative`, `/alerts/active`, and `/discussion`.
-
-Relevant docs: [Configuration reference](config.md).
-
-## Hourly Forecast Is Missing
-
-Symptom: generation fails with hourly forecast context, such as missing hourly
-data or an hourly forecast containing no periods.
-
-Likely cause: hourly forecast data is required for generated reports.
-
-Diagnostic: check the Weather API response for `/forecast/hourly`.
-
-Safe fix: restore hourly forecast data at the Weather API. Missing-source
-policy cannot make hourly optional.
-
-Relevant docs: [Configuration reference](config.md), [Operations guide](operations.md).
-
-## Source Warnings Appear
-
-Symptom: generation succeeds, but metadata or `inspect sources` shows source
-warnings.
-
-Likely cause: an optional source was missing or malformed under a warning
-missing-source policy.
-
-Diagnostic:
-
-```sh
-weatherreporter inspect sources RUN_ID
-weatherreporter inspect metadata RUN_ID
-```
-
-Safe fix: inspect the warning `source`, `code`, `message`, and `endpoint`. Fix
-the upstream optional source, or intentionally change the relevant
-`missing_source` policy.
-
-Relevant docs: [Configuration reference](config.md), [Operations guide](operations.md).
-
-## `scriptorium` Is Not Found Or Cannot Start
-
-Symptom: generation fails with `run scriptorium render` or `run scriptorium`
-and an executable or OS error.
-
-Likely cause: the configured Scriptorium binary is unavailable or not
-executable.
-
-Diagnostic: check `scriptorium.binary` in config and run the same binary outside
-`weatherreporter`.
-
-Safe fix: install Scriptorium, update `scriptorium.binary`, or fix executable
-permissions.
-
-Relevant docs: [Configuration reference](config.md),
-[Scriptorium integration](integrations/scriptorium.md).
-
-## Render Preflight Fails
-
-Symptom: generation fails with `scriptorium render exited with code ...`.
-
-Likely cause: Scriptorium rejected the prompt, config, profile, or
-`data_package` input before report generation.
-
-Diagnostic:
-
-```sh
-weatherreporter inspect metadata RUN_ID
-weatherreporter inspect data-package RUN_ID
-```
-
-Then read the preflight path from metadata. It contains captured stdout, stderr,
-exit code, and command.
-
-Safe fix: fix the Scriptorium configuration, prompt ID, profile, or data package
-input indicated by stderr.
-
-Relevant docs: [Operations guide](operations.md),
-[Scriptorium integration](integrations/scriptorium.md).
-
-## Scriptorium Run Fails
-
-Symptom: generation fails with `scriptorium run exited with code ...`.
-
-Likely cause: Scriptorium failed during report generation or validation.
-
-Diagnostic:
-
-```sh
-weatherreporter inspect metadata RUN_ID
-weatherreporter inspect data-package RUN_ID
-```
-
-If metadata includes a rendered report path, inspect that report as well. A
-nonzero run can still leave a managed report artifact.
-
-Safe fix: use the captured stderr and data package to fix the Scriptorium
-prompt, profile, model configuration, or validation issue.
-
-Relevant docs: [Operations guide](operations.md),
-[Scriptorium integration](integrations/scriptorium.md).
-
-## Batch Command Returns Nonzero
-
-Symptom: `run morning` or `run evening` returns nonzero.
-
-Likely cause: at least one report in the batch failed.
-
-Diagnostic: inspect stdout for the JSON summary and stderr for compact status
-lines.
-
-Safe fix: use the failed report's artifact paths from the summary, then inspect
-metadata, sources, module snapshot, and data package for that RunID.
-
-Relevant docs: [CLI reference](cli.md), [Operations guide](operations.md).
-
-## Invalid Secrets Directory
-
-Symptom: config loading fails with `read secrets directory`, `secret file`, or
-environment variable name context.
-
-Likely cause: `secrets.directory` points to a missing directory or contains an
-invalid entry. Secret entries must be regular files directly under the
-configured directory, and file basenames must match
-`[A-Za-z_][A-Za-z0-9_]*`.
-
-Diagnostic: list the configured directory and inspect entry names and file
-types. Do not print secret file contents.
-
-Safe fix: create the directory, remove subdirectories or symlinks, fix invalid
-filenames, and ensure the weatherreporter process can read each secret file.
-
-Relevant docs: [Configuration reference](config.md).
-
-## Distributor Token Is Missing
-
-Symptom: notification fails with a message that the distributor token
-environment variable is not set.
-
-Likely cause: `notify.distributor.enabled` is true, but the environment
-variable named by `notify.distributor.token_env` was not populated directly or
-through `secrets.directory`.
-
-Diagnostic: check `notify.distributor.token_env`, then verify a matching secret
-file exists under `secrets.directory` or that the process environment includes
-the variable. Do not print the token value.
-
-Safe fix: create a readable secret file whose basename matches `token_env`, or
-set the environment variable through the service manager.
-
-Relevant docs: [Configuration reference](config.md),
-[Operations guide](operations.md).
-
-## Distributor Upload Conflict
-
-Symptom: notification fails with idempotency conflict context.
-
-Likely cause: the same idempotency key was reused for different bundle content
-within the same distributor token and pipeline. By default the bundle ID is a
-stable report-stream identity and the idempotency key appends RunID.
-
-Diagnostic: inspect the failed batch JSON or stderr line for pipeline, bundle,
-and idempotency context. Compare the configured templates with the report RunID
-and report path.
-
-Also inspect the notification artifact linked from metadata. It records the
-rendered pipeline ID, bundle ID, idempotency key, upload result, distributor run
-status, status error, and raw run report JSON when available.
-
-Safe fix: keep idempotency templates stable for retries of the same generated
-report, but do not reuse the same rendered key for different generated report
-content.
-
-Relevant docs: [Operations guide](operations.md),
-[Distributor adapter internals](internal/distributor-adapter.md).
-
-## Distributor Upload Rejected
-
-Symptom: notification fails with distributor upload rejection, HTTP status, or
-bundle validation context.
-
-Likely cause: the distributor endpoint rejected the token, pipeline ID, bundle
-ID, idempotency key, source file, or one of the rendered bundle paths.
-
-Diagnostic: inspect stdout JSON or stderr status lines for
-`notificationError`. Confirm `notify.distributor.endpoint`,
-`notify.distributor.pipeline_id_template`,
-`notify.distributor.report_path_templates`, and token configuration. Token
-values are redacted from weatherreporter errors.
-
-If the upload was accepted but destination output did not change, inspect the
-notification artifact's `runStatus.report`. Distributor actions such as
-`replace_older`, `skip_same`, `skip_destination_newer`, or `failed` explain how
-the destination handled the uploaded bundle.
-
-Safe fix: fix the endpoint, token, templates, or distributor-side upload
-configuration. The weatherreporter upload source is the managed Markdown report,
-not `--out` or `--out-dir` copies.
-
-Relevant docs: [Configuration reference](config.md),
-[Operations guide](operations.md),
-[Distributor adapter internals](internal/distributor-adapter.md).
-
-## Distributor Unavailable
-
-Symptom: notification fails with network, timeout, or service unavailable
-context.
-
-Likely cause: the configured distributor endpoint is unreachable, slow, or
-temporarily unavailable.
-
-Diagnostic: check network access from the weatherreporter host to
-`notify.distributor.endpoint`. For batch runs, inspect which reports have
-`notificationStatus: "failed"`.
-
-Safe fix: restore distributor service availability and rerun the affected
-report or batch. Stable idempotency keys make retrying the same generated report
-safe unless the distributor reports a conflict.
-
-Relevant docs: [Operations guide](operations.md).
-
-## Unknown RunID
-
-Symptom: an inspect command fails with `metadata for run id ... was not found`.
-
-Likely cause: the RunID is mistyped or the command is reading a different
-workspace.
-
-Diagnostic:
-
-```sh
-weatherreporter inspect reports --config ./config.yml --limit 20
-```
-
-Safe fix: copy a RunID from `inspect reports`, or use the same `--config` and
-workspace that generated the report.
-
-Relevant docs: [Operations guide](operations.md).
-
-## Workspace Path Error
-
-Symptom: startup or inspection fails with workspace path validation or
-filesystem read/write context.
-
-Likely cause: a workspace subdirectory is absolute, escapes `workspace.root`, or
-the process cannot read or write the configured path.
-
-Diagnostic: review `workspace.root`, `workspace.snapshots_dir`,
-`workspace.reports_dir`, `workspace.data_packages_dir`, and
-`workspace.preflight_dir`.
-
-Safe fix: keep workspace subdirectories relative to `workspace.root`, and grant
-the process appropriate filesystem permissions.
-
-Relevant docs: [Configuration reference](config.md), [Operations guide](operations.md).
