 ## Quickstart
 
 ```sh
-weatherreporter generate today --out ./today.md
+weatherreporter generate today
 ```
 
+Configure a Weather API endpoint first; see the
+[configuration reference](docs/config.md). The report is written to

+# 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+continuously, so the useful response to an old, failed, or superseded report is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.

+the configured directory has the same role and `--out-dir PATH` selects its
+output directory instead. For `compare`, `--out-dir PATH` selects one exact
+bundle directory; otherwise the report-derived comparison directory is placed
+beneath the configured directory or current directory. `--replace` is required
+to replace an existing nonempty recognized comparison bundle. See the
+[configuration reference](config.md) for the field's validation and path rules
+and the [comparison bundle contract](integrations/comparison-bundle.md) for the
+bundle format.

-`--quiet` suppresses successful action-command stdout and routine stderr. It
+remains available.
-does not hide returned errors. Inspection commands are data-output commands;
-they always write the requested JSON to stdout and are not quietable.
 
-Generate summaries have this shape:
+`SIGINT` and `SIGTERM` cancel an active action. Weatherreporter lets that
+cancellation reach the action before exiting; when the action has a result, it
+emits the usual failed summary and exits nonzero. A canceled batch retains any
+reports that were already published, marks interrupted and unstarted reports
+as `canceled`, skips batch notification, and identifies cancellation separately
+from report failures.
+
+Action commands (`generate`, `run`, and `compare`) 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.
+
+`--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

 ## Field Reference
 
 ### `weather_api`
 
-- `base_url`: absolute base URL for the Weather API. Required for generation and collection workflows.
+| Field | Default | Rules |
-- `timeout`: HTTP timeout duration. Default: `10s`.
+| --- | --- | --- |
-- `precision`: numeric precision query value. Default: `1`.

+`Stl`, US timezone abbreviations, or signed UTC offsets such as `-5`, `+0930`,
+and `+09:30`. Numeric offsets require a sign, one or two hour digits, and an
+optional two-digit minute component with or without a colon. Hours must be
+from `00` through `23`, minutes from `00` through `59`, so the largest accepted
+offset magnitude is `23:59`.

+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.
+For `compare`, `--out-dir` selects its exact bundle directory; without it, the
+comparison's report-derived directory is placed beneath `output.directory`.
+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 HTTP(S) base URL with a host and no userinfo, query, or fragment. A path prefix is allowed. |
+| `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. |

+| `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.
+
+When notification is enabled, Weatherreporter validates the Distributor endpoint
+before prompt inspection, weather collection, or output publication. Use an
+HTTP(S) base URL such as `https://distributor.example.com/archive`; do not put
+credentials, a query string, or a fragment in the endpoint.

+
+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

+
+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. |

+# Comparison Bundle Contract
+
+A comparison bundle is the durable, flat artifact produced when one report is
+executed with multiple explicit Promptkit profiles. This document is the
+canonical contract for consumers of those bundles. Command invocation and JSON
+action summaries belong to the [CLI reference](../cli.md); destination handling
+and retention belong to the [operations guide](../operations.md).
+
+## Version And Layout
+
+The current and only supported manifest schema version is
+`weatherreporter.comparison.v1`. A bundle directory contains exactly these
+regular, non-symlinked files:
+
+```text
+comparison.json
+data-package.yml
+NN-profile-slug.md
+```
+
+`comparison.json` is the manifest and `data-package.yml` is the exact YAML
+input supplied to every selected profile. There is one Markdown file for each
+successful result and none for failed results. `NN` is the one-based selected
+profile position, zero padded to at least two digits (and widened only when
+needed for 100 or more profiles). The profile slug preserves ASCII letters,
+digits, `-`, and `_`; each run of other characters becomes one `-`; edge `-`
+and `_` characters are removed; the value is capped at 64 bytes; and an empty
+slug becomes `profile`. Logical profile IDs remain authoritative in the
+manifest.
+
+All manifest paths are basenames relative to the bundle root. They never use
+path separators, `.` or `..`. The CLI reports absolute paths only after a
+bundle has been published.
+
+## Manifest Schema
+
+The manifest is UTF-8 JSON, encoded as two-space-indented JSON with one
+trailing newline. Its fields appear in this order:
+
+```text
+schemaVersion, comparisonId, startedAt, finishedAt, reportId, validPeriod,
+timezone, promptId, promptVersion, promptHash, dataPackage, total, succeeded,
+failed, results
+```
+
+`validPeriod` contains `start` and `end`; it is a nonempty half-open period.
+`dataPackage` contains `path` (always `data-package.yml`) and `sha256` (the
+lowercase, 64-character SHA-256 digest of that file's exact bytes). `results`
+is in the explicit profile-selection order. Its result-object fields appear in
+this order:
+
+```text
+position, profileId, backendId, modelName, status, validationStatus,
+reportPath, error
+```
+
+`startedAt` and `finishedAt` are nonzero UTC timestamps, and the latter is not
+earlier than the former. `validPeriod` retains its resolved time offset.
+`reportId`, `timezone`, prompt identity, model name, and comparison ID are
+nonblank. `promptHash` and `dataPackage.sha256` are lowercase SHA-256 digests.
+
+## Result Invariants
+
+`total` is at least two and equals the number of results. Positions are
+contiguous from one, profile IDs are distinct and nonblank, and
+`succeeded + failed == total`.
+
+A successful result has `status: "succeeded"`, `validationStatus: "passed"`,
+a `reportPath` exactly equal to the canonical `NN-profile-slug.md` filename for
+its position, total, and logical profile ID, and no `error`. A failed result has
+`status: "failed"`, no `reportPath`, and an `error` object with nonblank
+`category` and `message`. Its validation status is absent, `failed`, or
+`skipped`. Error messages are valid UTF-8 and no longer than 1,024 bytes.
+`backendId` and `validationStatus` are omitted when unavailable.
+
+Every successful Markdown file is declared by exactly one successful result.
+The directory contains no extra entries. Consumers can therefore verify the
+data-package digest and the full manifest-to-file mapping without scanning a
+larger workspace.
+
+## Compatibility And Sensitivity
+
+Weatherreporter recognizes a replaceable bundle only when it exactly satisfies
+the current version, schema, file set, file types, relative-path rules, and
+data-package digest. JSON field names are case-sensitive canonical names and a
+field may appear only once in each manifest object. It rejects unknown,
+case-variant, or duplicate fields; multiple JSON values; extra entries;
+symlinks; and future or otherwise unsupported versions. Treat a bundle that
+fails recognition as an ordinary directory, not as a compatible bundle.
+
+When replacing a recognized bundle, cancellation observed before the new
+bundle is installed preserves the prior bundle rather than committing the
+replacement.
+
+Cleanup of a prior bundle occurs only after its replacement is committed and
+does not affect the new bundle's compatibility. A cleanup error may identify a
+complete recovery bundle, partial remnants, no remaining sibling, or an
+uninspectable state; this operational state is not recorded in the manifest.
+
+The manifest contains safe operational provenance, but `data-package.yml` and
+the generated Markdown can contain sensitive weather or location context. Do
+not assume these artifacts are safe for public distribution. Handle retention,
+access, and deletion according to the [operations guide](../operations.md).

-# 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 with a host as a base URL.
+It allows a path prefix but rejects userinfo, query strings, and fragments
+before local report work begins. The client posts a gzip-compressed source
+bundle to:
 
-The upstream application needs these values from deployment or operator configuration:
+```text
-
+POST /v1/pipelines/<pipeline_id>/upload
-- distributor endpoint: the HTTP server base URL, such as `https://distributor.example.com`;
+Authorization: Bearer <token>
-- upload token: bearer token that authenticates the producer;
+Content-Type: application/gzip
-- pipeline id: configured `http_upload` pipeline that should process this upload;
+Idempotency-Key: <key>
-- 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
 ```
 
-## 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
+The adapter requires nonblank pipeline ID, bundle ID, and idempotency key, plus
-package reports
+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 (
+Weatherreporter reads at most 1 MiB from each Distributor response. An

-For producer jobs that may retry after process restart, supply a key derived from the producer run, such as `<bundle-id>.<run-id>`.

-`Status` polls `/runs/<run-id>` while the distributor server retains the in-memory status record. Status values are `accepted`, `queued`, `running`, `succeeded`, and `failed`.

+# 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
+Every mapping pairs an operator-owned Markdown output with one bundle-relative
-import "gitea.maximumdirect.net/eric/distributor/pkg/bundle"
+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
+The upstream canonical file-format contract is
-manifest, err := bundle.WriteBundle(bundle.WriteBundleOptions{
+`docs/integrations/source-bundle.md` in the Distributor repository. It defines
-	Root: "/var/spool/distributor/weather/hourly-2026-06-07T15",
+the complete manifest and archive format; this page records only the mapping and
-	ID:   "weather.hourly.brentwood",
+path constraints Weatherreporter relies on.
-	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 reserved basename, including `manifest.json` and the distributor sidecar
-  basename formed from a leading dot plus `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.

+# 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
+The adapter constructs the client with the prevalidated HTTP(S) endpoint,
-import "gitea.maximumdirect.net/eric/distributor/pkg/upload"
+bearer token, and an HTTP client whose timeout is the configured Distributor
-```
+timeout. The endpoint may include a path prefix but never userinfo, a query, or
+a fragment. It passes no custom retry options, so the pinned client's defaults
+apply: three attempts, 100 ms base delay, and one-second maximum delay.
+The adapter bounds every response to 1 MiB before handing it to the pinned
+client. A response above that boundary is rejected as a local overflow rather
+than decoding or retaining a prefix.
 
-`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
+It leaves bundle validation enabled. `UploadFiles` creates the temporary source
-import "gitea.maximumdirect.net/eric/distributor/pkg/bundle"
+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
+The client decodes the accepted upload result (`run_id`, `status`) and the run
-client, err := upload.NewClient(upload.ClientOptions{
+status record. A `409` response is an upstream idempotency conflict; the
-	Endpoint: "https://distributor.example.com",
+adapter translates it to its own conflict error without exposing the token.
-	Token:    token,
-})
-if err != nil {
-	return err
-}
-```
 
-`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. Normal diagnostics use local status classifications; they
+do not expose remote response text or the status report. 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
+The upstream package workflow is documented in
-
+`docs/consumers/pkg-upload.md` in the Distributor repository. Weatherreporter
-Use `UploadFiles` when the producer has generated output files but has not assembled a bundle directory.

+`Status` operations described here.
-```go

-	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.

+# 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 report's exact generated-text report/schema/template catalog binding, prompt version and hash, output contract, and selected profile. Active profiles must resolve a nonblank backend and model identity. 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. Before accepting that JSON, Weatherreporter requires exactly one preparation callback and reconciles its prompt/profile/backend/model and rendered/input hashes with the inspected identity and completed result. The callback output contract and completed validation must use the report's expected JSON Schema mode and path. The package contains only reviewed prompt-facing warning summaries, never source transport or provenance details. Safe active provenance remains in memory. Content-rich diagnostics are opt-in through `--llm-debug-dir`; see [operations](../operations.md) for retention and permissions.
+
+When capture is enabled, its preparation artifact projects a provider endpoint
+to its scheme and host and retains only reviewed execution settings. Provider
+extras and URL user information, paths, queries, and fragments are omitted.
+Capture storage remains confined to the operator-selected debug root; an unsafe
+filesystem path causes the requested execution to fail. Host availability and
+operator handling are documented in the
+[operations guide](../operations.md#optional-prompt-debug-capture).
+
+## Comparison Execution
+
+For `compare`, Weatherreporter validates the report's generated-text catalog
+binding, one exact prompt, and every explicitly selected profile before weather
+collection. It prepares one deterministic YAML
+data package, retains immutable copies of the report inputs, and executes every
+profile against the same exact data-package bytes. Each profile remains an
+independent Promptkit execution: one provider, provenance, or validation failure does not
+stop its peers, while caller cancellation applies to every in-flight execution.
+
+Weatherreporter starts selected profile executions concurrently and does not
+add an application-level concurrency limit. Promptkit owns backend capacity and
+any profile or backend concurrency policy. A shared Weatherreporter executor
+must safely accept those concurrent `Execute` calls. The durable comparison output and
+its compatibility rules are defined by the
+[comparison bundle contract](comparison-bundle.md); the user-facing command
+contract is in the [CLI reference](../cli.md).
+
+The generated-text schemas require `summary`, `forecast_discussion`, and `precipitation_timing`, and reject additional properties. Promptkit results are accepted only when their raw JSON is at most 64 KiB; the adapter drops larger results before copying them into Weatherreporter's execution values or debug artifacts. The validator also limits total generated prose to 20,000 characters, with 4,000-character summary and timing fields, a 12,000-character Hourly discussion, and at most 12 day-style paragraphs of 4,000 characters each. 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 report artifacts. 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>
-```
-
-Structured generated-text report generation uses the same command shape:
-
-```bash
-scriptorium run \
-  --prompt <prompt_id> \
-  --input data_package=<path> \
-  --out <generated_text_raw_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.
-
-For generated-text reports, Scriptorium selects the structured output schema
-from the prompt configuration associated with the prompt ID. `weatherreporter`
-does not pass `--format`, schema path, or JSON Schema flags for structured
-generation.
-
-## 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. Structured
-generated-text run results use the same captured fields and output-path
-recording, with the output path pointing at the raw generated-text JSON
-artifact.
-
-`weatherreporter` persists render preflight JSON when orchestration reaches the
-preflight save point. For direct Markdown reports, Scriptorium writes the
-managed Markdown artifact to the `--out` path. For generated-text-template
-reports, Scriptorium writes raw JSON to the `--out` path; later
-weatherreporter workflow steps validate those bytes and render Markdown from an
-embedded template.
-
-## Failure Behavior
-
-The adapter validates required request fields before starting Scriptorium:
-
-- prompt ID
-- data package path
-- output path for `run` and structured generated-text `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.

-## Endpoints Used
+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.
 
-The adapter fetches these endpoints once per bundle:
+The adapter accepts response bodies up to 10 MiB and rejects larger bodies
+before decoding. A non-2xx response reports its relative endpoint and status,
+without including upstream response text. Request construction, response-limit,
+read, and decode failures include endpoint context in their errors.
 
-- `/observations`
+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.

-- `/alerts/active`
-- `/discussion`
-- `/weatherstories/latest`
-- `/outlooks/convective`
-
-`weatherreporter` does not call day-slice forecast endpoints or discussion
-subsection endpoints. Report-period selection and daypart summarization happen
-inside Go after the full hourly and narrative products are fetched.
-
-## Required And Optional Sources
-
-Hourly forecast is required:
-
-- `data: null` for `/forecast/hourly` fails the fetch.
-- an hourly forecast with no `periods` fails the fetch.
-- malformed hourly data fails the fetch.
-
-Other fetched sources are optional and follow `missing_source.default` or a
-source-specific `missing_source.sources` policy:
-
-- `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` for `/outlooks/convective`
-
-Policy behavior:
-
-- `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
-
-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.
-
-For `/outlooks/convective`, a non-null data object with empty outlook and
-discussion arrays is accepted as checked empty data.
-
-## Source Identity
-
-For source payloads accepted into the bundle, including the explicit `null`
-alerts payload, the adapter records:
-
-- 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 weather data
-bundle types in `internal/weatherdata/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
-- SPC convective outlook run metadata, outlooks, discussions, and GeoJSON
-  geometry
-
-The adapter intentionally keeps upstream transport and envelope details inside
-`internal/adapters/weatherapi`; downstream packages consume the normalized
-bundle.

-This document describes the workflow coordinator in `internal/app`.
+`internal/app` owns stateless report generation, batch execution, comparison
+orchestration, 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
+`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. Output preflight validates the final filename, permits only an absent or regular final destination, and validates the bounded same-directory temporary form without creating a missing parent. It then validates the report's generated-text catalog binding, exact Promptkit prompt, and selected profile before collecting weather data. The resolved profile, backend, and model are carried in the active result.
-loading are complete. It resolves report definitions, collects weather data
-through `internal/collect`, 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.
 
-## Inputs And Outputs
+The workflow builds facts, a module snapshot, briefing metadata, and the YAML prompt package in memory. It executes Promptkit only against the inspected prompt and profile, reconciles the preparation callback and completed result with that identity and the prepared report schema, validates the returned generated text, builds a render context, and renders Markdown. `fileutil` writes the completed Markdown through a same-directory temporary file, rechecks the final destination and context after close and immediately before the atomic rename. 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.

+## Batches
-- `BatchRequest` for morning or evening batch commands
-- `FetchBundleRequest` for explicit bundle collection and save workflows
-- `ReportRequest` for single-report generation
-- resolved report definitions from `internal/report`
-- collection results from `internal/collect`
-- prior snapshots loaded from `internal/state`
-- optional collector, renderer, notifier, and state-store fakes for tests
 
-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 generated-text catalog, 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,
+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
+Cancellation and deadline expiry stop the sequential loop before another report
+starts. Completed report results and published paths remain successful; the

+Focused checks:
 
-Single-report commands validate the report command, collect once through
+```sh
-`internal/collect`, resolve the requested report, and pass the resolved report

-plus explicit collection into `GenerateReport`. `GenerateDetailed` returns the
+```
-resulting `ReportResult`; `Generate` wraps the same workflow for error-only
-callers.
-
-`GenerateReport` then uses this setup:
-
-1. Create or use a filesystem store.
-2. Locate any prior compatible snapshot through `internal/state`.
-3. Build collected and derived facts from the supplied collection.
-4. Execute configured modules and save the module snapshot.
-5. Compute Recent Changes from structured prior and current module snapshots.
-6. Build and save the YAML Scriptorium `data_package`.
-7. Run Scriptorium render preflight.
-8. Save preflight JSON when a render result is available.
-9. Save metadata for inspection.
-
-For `scriptorium_markdown` reports, generation then:
-
-10. Runs Scriptorium report generation to the managed report path.
-
-For `generated_text_template` reports, generation then:
-
-10. Looks up the generated-text catalog entry for the report schema/template
-    IDs.
-11. Runs structured Scriptorium generation to the raw generated-text JSON path.
-12. Saves the structured Scriptorium run result.
-13. Validates and saves normalized generated text.
-14. Builds and saves a typed render context.
-15. Renders Markdown from the embedded template to the managed report path.
-
-After either mode has produced a managed Markdown report, shared finalization:
-
-1. Copies the managed report to the requested `--out` or `--out-dir` path when
-   provided.
-2. Saves final metadata with the managed report path and any generated-text
-   artifact paths already produced.
-3. If distributor notification is enabled, notifies using the managed report
-   path as the source file.
-4. Saves a distributor notification debug artifact and updates 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 collection,
-module snapshot, prompt input, render, Scriptorium run, or metadata-save
-failures.
-Generated-text report failures are returned with report ID, RunID, and the
-failed operation. When available, the app preserves the latest generated-text
-artifacts already reached by the workflow: preflight output, structured run
-result, raw generated text, validated generated text, and render context.
-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` collects once, plans Today Report, Tomorrow Report, and eligible
-future Daily Reports from the collected hourly forecast, then passes the same
-collection into each report generation. `run evening` uses the same collection
-and planning rules, but starts with Tomorrow Report. Future Daily reports start
-with the day after tomorrow and require complete hourly forecast coverage for
-the target local civil day. Dynamic Daily `--out-dir` copies use
-`daily-YYYY-MM-DD.md`; other batch copies use report definition output names.
-A collection failure stops the batch before planning or report generation.
-After planning succeeds, 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.
-
-Batch report generation suppresses per-report distributor notification. After
-all planned reports finish, app orchestration evaluates batch notification:
-
-1. If distributor notification is disabled, the batch notification result is
-   omitted.
-2. If batch notification is disabled, the batch notification result is omitted
-   and there is no per-report fallback upload.
-3. If any planned report failed, the batch notification result is `skipped`
-   with reason `one or more reports failed`, and distributor is not called.
-4. If every report succeeded, app orchestration renders batch pipeline, bundle
-   ID, and idempotency key templates, renders report-specific distributor
-   paths for each included report, validates every managed source path and
-   bundle path, checks duplicate bundle paths across the batch, calls the
-   notifier once with a multi-file request, and saves a batch notification
-   debug artifact.
-
-Batch notification failure records a top-level failed notification, increments
-the aggregate batch failure count, and returns an aggregate batch error without
-marking individual report items failed. `--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 collection.
-- Collection 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.
-- Generated-text report errors preserve available intermediate artifacts and do
-  not create extra output copies.
-- Single-report notification errors are wrapped with report ID, RunID, and
-  managed report path context. Detailed generation returns the inspectable
-  report, metadata, and notification artifact paths when finalization has
-  already saved them.
-- Batch notification errors are recorded on the top-level batch notification
-  result and do not change individual report item status.
-- 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/app/batch_plan_test.go`
-- `internal/collect/collect_test.go`
-- `internal/cli/root_test.go`
-- `internal/state/filesystem_test.go`
-
-## Invariants
-
-- Report behavior is resolved through `internal/report`.
-- Generate and run commands collect once before report generation.
-- Batch planning is app-owned because future Daily membership depends on
-  collected hourly forecast coverage.
-- Generated reports use the same app request and result types regardless of
-  report ID.
-- Render preflight precedes Scriptorium report generation.
-- Generated-text reports render Markdown from a curated render context, not from
-  a raw data package.
-- Recent Changes are computed from structured module snapshots.
-- Metadata links artifacts produced for a run.
-- Single-report distributor notification maps the managed Markdown report path
-  to configured bundle paths.
-- Batch distributor notification maps each included managed Markdown report
-  path to bundle paths rendered for that report and uploads once for the
-  batch.
-- 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.

-`area_forecast_discussion` uses optional `sections` configuration to include a
-subset of discussion fields. Hourly Report defaults this module to
-`key_messages` and `short_term`; Daily Report defaults it to `long_term`.
-
-`spc_convective_outlooks` uses collected SPC run metadata and derived

-empty run, reports `outlook_count`, and includes prompt-facing outlook fields
-such as risk label, `period_begins`, `period_ends`, image URL, and whether the

-for categorical outlooks that overlap the report period, contain the location,
-and meet the configured-in-code minimum severity for report rendering. It does
-not emit GeoJSON geometry, source URL, expiration time, or severity rank.
-
-Prompt-facing module intervals use friendly local `period_begins` and
-`period_ends` labels. Canonical report metadata, source provenance,
-`issued_at`, `updated_at`, and point-in-time fields remain separate.
-
-`spc_convective_discussion` uses the same derived report-period outlooks and

-
-## External Adapters Used

-## 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

-
-## Failure Behavior
-
-- Required derived modules return errors when their dependent facts are not

-- Composition validation rejects unknown modules, duplicate modules,
-  incompatible report/module combinations, duplicate stanza names, and invalid

-## Purpose
+The root `--version` flag reports the build version supplied by `internal/buildinfo`. Tagged release builds replace its development default at link time.

-## Command Categories
+For each `generate`, `run`, or `compare` action, `Runner` constructs one project-owned Promptkit executor after request preflight and configuration loading. 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`.

-## Quiet Mode
-
-`--quiet` is supported only by action commands. It suppresses successful stdout

-`writeActionResult`. It does not suppress returned errors.
-
-Quiet mode is intentionally not accepted by inspection commands because

-

-  the generate JSON contract.
-- `newBatchSummary` converts `*app.BatchResult` into the run JSON contract and

-
-Summary types must not expose full app internals, module contents, data package
-contents, raw generated text, Scriptorium result bodies, or full distributor
-payloads.
-
-## Helper Path
-
-New action commands should:
-
-1. parse command-specific flags into CLI option structs;
-2. call the app-layer use case;
-3. convert app results into a CLI summary type;
-4. write through `writeActionResult`;
-5. use a status writer only for routine stderr status lines.
-
-New inspection commands should call the app inspection use case and write the
-returned data through `writeJSON`.

+# Comparison Execution Internals
+
+The comparison execution core receives an already prepared report and an
+already inspected, ordered profile list. It initializes an outcome for every
+selected profile, launches each started profile in its own goroutine, and
+waits for every started goroutine before returning. Results retain the supplied
+selection order even though execution completes in an arbitrary order.
+
+Every profile uses the exact inspected prompt identity and a private copy of
+the same prepared data package. Provider, generated-text validation, rendering,
+or debug-write failure becomes that profile's safe failed outcome and does not
+cancel its peers. The shared executor must support those concurrent `Execute`
+calls. The application deliberately imposes no additional semaphore: Promptkit
+owns backend capacity. A profile failure completed before a later cancellation
+remains its original safe outcome; cancellation or a deadline marks only
+unfinished or cancellation-terminated outcomes as skipped or failed, joins work,
+and prevents bundle publication.
+
+When debugging is enabled, each execution receives a deterministic reference
+derived from the comparison identity, ordered profile position, and safe
+profile slug. This keeps concurrent captures separate. The debug writer itself
+owns secure-root validation and file permissions. It safely creates shared
+missing ancestors during concurrent writes, then rejects symlink and non-
+directory components. Operational retention and sensitivity are documented in
+the [operations guide](../operations.md). This secure writer is enabled only on
+Unix hosts; comparison fails before execution when another host requests debug
+capture.
+
+The output result and its safe errors are converted into the durable contract
+only by comparison publication. See [comparison publication

+contract](../integrations/comparison-bundle.md).

+# Comparison Publication Internals
+
+`internal/comparison` separates the logical bundle from filesystem mechanics.
+The application builds a validated manifest, exact shared data-package bytes,
+and only the Markdown files for successful profiles. The durable layout,
+schema, and compatibility rules are owned by the [comparison bundle
+contract](../integrations/comparison-bundle.md).
+
+Recognition first token-validates the manifest's object fields, rejecting
+unknown, case-variant, and duplicate names before decoding its typed schema.
+Manifest validation derives each successful report filename from its ordered
+position, total profile count, and logical profile ID; logical-bundle and
+filesystem validation then require that exact path and file set.
+
+Destination planning is read-only. It requires an exact absolute target that
+is neither the filesystem root nor the working directory, rejects unsafe
+symlinks and non-directories, accepts a missing or empty directory, and permits
+replacement only for a recognized current bundle. Publication rechecks the
+destination namespace and type immediately before it writes a private sibling
+staging directory. For replacement, it moves the prior bundle to a private
+sibling backup, fully reauthorizes that moved entry, checks for cancellation,
+and restores it if cancellation or installing the new bundle prevents
+replacement. If guarded restoration fails, the error retains the prior bundle's
+recovery path.
+
+Planning also validates the final component and the bounded fixed names used
+for private staging and backup siblings. A destination that cannot form those
+names is rejected before publication creates a missing parent directory; a
+maximum-length valid destination remains usable because transaction siblings do
+not incorporate its basename.
+
+The new bundle is committed only after the staged directory has been installed
+at the target. From that point its artifact paths are authoritative: a failure
+to remove the retained sibling backup does not roll back the new bundle.
+After a cleanup failure, publication inspects the sibling without masking the
+original filesystem cause. Its inspectable cleanup result distinguishes a
+complete recognized recovery bundle, partial remnants, an absent sibling, or
+an uninspectable state. A recovery path is reported only when something
+remains; only a complete recognized bundle is suitable for rollback recovery.
+
+The application preflights before prompt inspection and collection. Publication
+performs its transaction-boundary checks and final moved-destination
+authorization before installation. A cancellation or any failure before the
+commit leaves the prior destination untouched. Completed bundles include
+partial profile results; comparison publication never coordinates Distributor
+notification. Operator-facing lifecycle and cleanup are in the
+[operations guide](../operations.md).

-## Inputs And Outputs
+The upstream client is an implementation dependency, not a source of

+templates, and report rendering are defined by
+[configuration](../config.md) and [application orchestration](app-orchestration.md).
 
-Inputs:

+Before calling the dependency, `Upload` validates the endpoint and token

+Remote response bodies, status reports, and remote error text are not retained

-The app layer passes weatherreporter-owned request values to the adapter. The

+## Verification
-`docs/integrations/distributor/`.
 
-## Config Fields Used
+Focused tests cover configuration validation, request mapping, response size
+boundaries, safe diagnostics, timeouts and polling, status translation, conflict
+handling, and token redaction. A local HTTP server exercises the production
+upload and status boundary:
 
-The adapter is built from `notify.distributor` config:
+```sh
-
+go test ./internal/adapters/distributor
-- `endpoint`
+```
-- `token_env`
-- `timeout`
-
-The app layer renders single-report pipeline ID, bundle ID, idempotency key,
-and bundle paths from:
-
-- `pipeline_id_template`
-- `bundle_id_template`
-- `idempotency_key_template`
-- report-specific path templates
-
-For batch uploads, the app layer renders pipeline ID, bundle ID, and
-idempotency key from `notify.distributor.batch.*`, resolves report-specific
-path templates once per included report, and passes the resulting multi-file
-request to this adapter.
-
-Report-specific path resolution happens entirely in the app layer. Explicit
-`reports.<report>.distributor.path_templates` overrides take precedence over
-report definition defaults.
-
-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 paths: managed Markdown report paths selected by app orchestration
-- bundle paths: rendered bundle-relative report paths for each source
-- created: the report or batch 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.

-distributor service.
-
-## Invariants

-  uploaded.
-- The adapter never scans the workspace.
-- Token values are not included in errors, CLI output, metadata, docs, or

+Daily, Today, and Tomorrow use a day-style value with required trimmed summary

-

-
-- display metadata derived from report metadata;
-- validated generated text;
-- typed module outputs decoded from the module snapshot;
-- collected facts;
-- derived facts.
-
-Daily, Today, and Tomorrow share common civil-day render-context fields such as
-forecast date labels, valid period, generated-at labels, current conditions,
-hourly forecast, precipitation timing, alert digest, SPC outlooks, AFD, SPC
-discussion, weather story, daily summary, and ordered daypart summaries.
-
-Each civil-day report keeps its report-specific planning module:
-
-- Daily exposes `DailyPlanning`.
-- Today exposes `TodayPlanning`.
-- Tomorrow exposes `TomorrowPlanning`.
-
-Today's ordered daypart context omits unavailable or elapsed dayparts according
-to Today report rules. Daily and Tomorrow use fallback daypart behavior.
-
-## Boundaries
-
-- This package owns typed generated-text validation and render-context shaping.
-- It owns generated-text catalog lookup for schema/template combinations.
-- It uses typed module snapshot decoding through `module.StanzaValue`.
-- It does not invoke Scriptorium, write state artifacts, choose report
-  definitions, compare snapshots, or own embedded template/schema files.
-- It renders through `internal/reporttemplate`; embedded asset lookup remains
-  in `internal/reporttemplate`.
-- It does not use a Go JSON Schema dependency; schema enforcement in Go is
-  limited to typed JSON decoding, unknown-field rejection, and required-field
-  checks.
-
-## Failure Behavior
-
-- Malformed generated-text JSON fails with decode context.
-- Unknown generated-text JSON fields fail during decoding.
-- Empty required fields fail after trimming whitespace.
-- Daily, Today, and Tomorrow forecast discussion fails when no nonblank
-  paragraphs remain.
-- Missing optional render-context stanzas become nil module pointers.
-- Invalid render metadata, including missing timezone, missing generated time,
-  or invalid valid period, fails before template rendering.
-- Unsupported generated-text schema IDs, template IDs, or schema/template
-  combinations fail during catalog lookup with report ID context.

-- `internal/generatedtext/render_context_test.go`
-
-## Invariants
-
-- Render contexts are curated structs, not raw prompt-input packages.
-- Required generated text is normalized before downstream artifact storage.
-- Generated-text-template reports must have one catalog entry matching their
-  report definition schema and template IDs.
-- Missing optional weather narrative stanzas produce empty or fallback render
-  context fields rather than forcing raw module data into templates.

 # Module Contract Internals
 
-This document describes the module contract in `internal/module`.
+`internal/module` defines the 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;

+`NewSnapshot` builds and validates the ordered in-memory snapshot. Its JSON
+representation carries a package-owned schema marker, 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.

-- `module.Snapshot` with schema version `weatherreporter.modules.v1`
-- ordered snapshot outputs with module ID, stanza name, and typed value
-- runtime-only prompt export values on module outputs
-- `module.Output.DataPackageValue`, which selects the prompt export value and

-
-## Daily Planning
-
-`daily_planning` emits dated daily planning facts for the `daily` report ID.
-Its output stanza is also named `daily_planning`. The module is supported only
-by that report ID and depends on daily summaries for the selected local civil
-day. The default Daily Report composition includes it.
-
-The output uses this shape:
-
-- `morning_readiness`
-- `commute_school_workday_concerns`
-- `overnight_change_watch`
-
-The type is `briefing.DailyPlanningModule`; it is independent from
-`briefing.TomorrowPlanningModule`.
-
-## Today Planning
-
-`today_planning` emits current-day planning facts for Today Report. Its output
-stanza is also named `today_planning`. The module is supported only by Today
-Report and depends on daily and daypart summaries for the current local civil
-day.
-
-The output uses this shape:
-
-- `morning_readiness`
-- `commute_school_workday_concerns`
-- `outdoor_planning`

-Hourly Report does not include daily or daypart summary modules by default.
-Its `area_forecast_discussion` item is configured to include only
-`key_messages` and `short_term`.

-## Options
-
-Most modules use an empty options struct, including

-## 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, collect 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. Snapshot JSON contains rich module values only; runtime prompt
-export values are not persisted.
-
-## Failure Behavior
-
-- Snapshot construction fails for duplicate module outputs or duplicate stanza
-  names.
-- Typed stanza lookup returns `found=false` for missing stanzas.
-- Typed stanza lookup wraps JSON marshal/decode failures with stanza context.
-
-## Tests
-
-Inspect:
-
-- `internal/module/module_test.go`
-- `internal/briefing/modules_test.go`
-- `internal/report/period_test.go`
-
-## Invariants
-
-- `internal/module` does not import `internal/report`.
-- Module IDs are stable strings.
-- Each emitted module output has exactly one stanza name and one rich typed
-  value.
-- Built module outputs have a data-package value, either from a custom prompt
-  exporter or from default pass-through behavior.
-- Snapshot output order is caller-owned and preserved.

+# Prepared Report Internals
+
+`internal/app` validates the report's generated-text catalog binding during
+prompt inspection, before collection, and carries the resulting handler into
+`preparedReport` construction after collection. This is the immutable boundary
+shared by ordinary report generation and profile comparison; it is not a
+durable artifact.
+
+Preparation first establishes one `PreparedIdentity` for the report run, report
+and prompt IDs, variant, generation time, units, timezone, valid period,
+location, and source warnings. It passes that identity to the configured module
+snapshot, curated prompt-input package, serialized YAML, generated-text render
+context, and generated-text definition. Each boundary projects only the fields
+it needs from that prepared authority.
+
+Preparation deep-copies mutable facts, snapshots, identity, and data-package
+bytes before returning them. Consumers receive independent copies so one
+execution cannot change another's input or rendering context.
+
+Before accepting generated JSON, the execution boundary reconciles the prepared
+report definition, inspected prompt hash and selected profile identity, the one
+preparation callback, and the completed Promptkit result. The callback and
+completion must agree on prompt, profile, backend, model, and rendered/input
+hashes; the callback output and completed validation must name the prepared
+report's JSON Schema. A mismatch produces no rendered Markdown and leaves
+results with only the inspected safe identity.
+
+Single-report generation executes one prepared profile and publishes its
+Markdown. Comparison prepares once, gives every selected profile the same YAML
+bytes, and only then assembles the resulting logical bundle. The prompt-input
+shape is owned by [prompt-input internals](prompt-input.md); profile execution
+semantics are owned by [Promptkit integration](../integrations/promptkit.md).
+
+Catalog incompatibility stops prompt inspection before weather collection or
+model work. Preparation failure has no publication side effects. Tests for this
+boundary cover catalog-preflight ordering, mutation isolation, byte equality,
+and reuse by both execution paths.

-`internal/promptinput` converts report metadata, ordered module outputs, Recent

-## Inputs And Outputs
+This package does not collect weather, choose an output destination, execute a
+provider, or persist data packages. The application passes its in-memory YAML
+to the Promptkit adapter as part of prepared report execution.
 
-Inputs:
+## Verification
 
-- report metadata from app/state orchestration
+Focused tests cover package construction, report-local dates, validation,
-- `module.Snapshot`
+curated snapshot exports, deterministic YAML grouping, and safe source-warning
-- optional `[]changes.Change`

-  module stanzas grouped for prompt presentation, Recent Changes, and source
-  warnings
-- YAML bytes from `promptinput.MarshalYAML`
-- YAML file written atomically by `promptinput.Save`
-
-The YAML shape includes:
-
-```yaml
-schema_version: weatherreporter.data_package.v3
-run_id: <run_id>
-report:
-  id: <report_id>
-  prompt_id: <prompt_id>
-briefing:
-  metadata: {}
-  applicable_risk_products:
-    alert_digest: {}

-recent_changes:

 ```
-
-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.
-Prompt-facing module intervals use local `period_begins` and `period_ends`
-labels; canonical report metadata and source timestamps remain structured
-timestamps where applicable.
-
-## Module Export Boundary
-
-Data packages are curated prompt inputs. They are not full template render
-contexts and should not be treated as a dump of every field available to Go
-templates.
-
-When module outputs are built by `internal/briefing`, the registry attaches a
-runtime prompt export value. `internal/promptinput` serializes
-`output.DataPackageValue()` for each stanza. That helper prefers the runtime
-prompt export and falls back to the rich `Value` when no prompt export is set,
-which keeps loaded snapshots and hand-built tests usable.
-
-Modules without custom export policy use pass-through behavior. Modules with
-custom exports currently include:
-
-- `current_conditions`: omits lower-case condition text and duplicate
-  wind-direction text.
-- `hourly_forecast`: omits hour labels, lower-case description text, and the
-  template precipitation-mention helper while keeping forecast facts.
-- `derived_daypart_summaries`: omits deterministic sentence-construction
-  helpers while keeping daypart period, condition, temperature trend,
-  precipitation, wind, notable-condition, hazard, and alert-relevance facts.
-
-The rich module snapshot and generated-template render context still contain
-the helper fields used by deterministic Markdown templates.
-
-Daily Report, Today Report, Tomorrow Report, and Hourly Report module snapshots
-use the same package schema and categories when converted into prompt input.
-The default hourly module list places
-`precip_timing` under `derived_summaries`, alert and SPC outlooks under
-`applicable_risk_products`, AFD/SPC discussion/weather story under
-`narrative_products`, and current/hourly data under `raw_data`. It does not
-include civil-day summary stanzas. Generated-text and render context artifacts
-are produced later in app orchestration and are not part of the YAML data
-package.
-
-The default Daily, Today, and Tomorrow module lists include civil-day summary
-stanzas, planning stanzas, and `hourly_forecast` in the data package before
-structured GeneratedText is requested from Scriptorium. Daily uses
-`daily_planning`, Today uses `today_planning`, and Tomorrow uses
-`tomorrow_planning`.
-
-Current categories are:
-
-- `applicable_risk_products`: location-applicable alerts, warnings, outlooks,
-  and similar risk products. Current stanzas include `alert_digest` and
-  `spc_convective_outlooks`.
-- `derived_summaries`: deterministic summaries and calculated report facts.
-- `narrative_products`: official narrative text products and forecast stories.
-  Current stanzas include `narrative_forecast`,
-  `area_forecast_discussion`, `spc_convective_discussion`, and
-  `weather_story`.
-- `raw_data`: minimally transformed underlying weather data.
-
-## Boundaries
-
-- This package owns prompt package schema, YAML marshaling, YAML loading, and
-  validation.
-- It does not collect weather data, derive forecast summaries, execute modules,
-  choose module prompt export shapes, 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
-`internal/state`.
-
-## Skip And Resume Behavior
-
-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
-missing or inconsistent, when the valid period is invalid, or when no module
-stanzas are present. Save failures include filesystem operation and path
-context.
-
-## Tests
-
-Inspect:
-
-- `internal/promptinput/package_test.go`
-- `internal/app/app_test.go`
-
-## Invariants
-
-- Scriptorium receives structured YAML through `--input data_package=<path>`.
-- Module stanza order is deterministic within each prompt-facing category.
-- Every non-metadata module stanza has exactly one prompt-input category.
-- Data-package stanzas use curated module prompt exports when present and rich
-  values only as pass-through or fallback values.
-- Data packages are narrower than generated-template render contexts.
-- Recent Changes are provided by `internal/changes`; this package does not
-  infer changes from rendered report text.

+# 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).

-## Reports
-

-| --- | --- | --- | --- | --- | --- | --- |
-| Daily Report | `daily` | `weather.daily_generated_text` | `generated_text_template` | `daily` | `daily.md` | Daily Report |
-| Today Report | `today` | `weather.today_generated_text` | `generated_text_template` | `today` | `today.md` | Today Report |
-| Tomorrow Report | `tomorrow` | `weather.tomorrow_generated_text` | `generated_text_template` | `tomorrow` | `tomorrow.md` | Tomorrow Report |

-| Weekend Outlook | `weekend` | `weather.weekend_outlook` | `scriptorium_markdown` | `weekend` | `weekend.md` | Weekend Outlook |
-| Storm Report | `storm` | `weather.storm_report` | `scriptorium_markdown` | `storm` | `storm.md` | Storm Report |
-
-All report definitions are eligible for generation.
-
-## Valid Periods
-
-- Daily Report covers the selected local civil day and requires an explicit
-  date.
-- Today Report covers the selected local civil day, or the current local civil
-  day when no date override is supplied.
-- Tomorrow Report covers the next local civil day from generation time.
-- Hourly Report covers the half-open six-hour period from generation time in
-  the effective report timezone. The duration is an internal report constant,
-  not a configuration field.
-- 3-Day Outlook covers the interval from generation time through local midnight
-  three days later.
-- Weekend Outlook covers the upcoming weekend window.
-- Storm Report covers an explicit event window supplied by the caller.
-
-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.
-
-## Boundaries
-
-`internal/report` defines report metadata, public report names, batch command
-names, output naming, and time coverage. It does not collect weather data, plan
-batch membership, build module values, compare snapshot contents, write state,
-parse CLI flags, or invoke Scriptorium.
-
-The CLI parses flags and command structure, then uses report-owned helpers for
-report and batch command names. Config loading uses report-owned helpers for
-report override keys.
-
-## 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. Report
-module overrides can use short keys such as `daily`, `today`, `tomorrow`, and
-`hourly`, or descriptive names such as `three_day_outlook`.
-
-## Batch Commands
-
-`internal/report` owns the public batch command names `morning` and `evening`
-and validates them through `BatchForCommandName`. Data-dependent batch
-membership is owned by `internal/app`, because it depends on collected hourly
-forecast coverage.
-
-Report definitions still declare default batch output copy filenames. App
-batch planning uses those filenames for fixed report entries and supplies
-date-qualified names for dynamic Daily entries.
-
-## 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.
-- Public command names, config-key aliases, and batch command names are owned
-  by `internal/report`.
-- Direct Markdown reports have empty template and generated-text schema IDs.
-- Generated-text-template reports declare prompt, template, and schema IDs in
-  their report definition.
-- 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.
-- App-owned batch planning uses report definitions but does not live in the
-  report registry.

-
-## Boundaries
-
-This package owns embedded asset lookup, Go template parsing, and Markdown
-template execution. It does not collect weather data, build module outputs,
-validate GeneratedText, construct render contexts, choose report definitions,

-
-GeneratedText validation is owned by `internal/generatedtext`. App
-orchestration uses `internal/generatedtext` catalog lookup to connect
-`internal/report` definition schema/template IDs to the matching validator,
-render-context builder, and embedded assets.
-
-## Template Contracts
-
-Daily, Today, Tomorrow, and Hourly rendering use typed render contexts with:
-
-- report metadata labels such as title, location, valid period, and generation
-  time
-- validated GeneratedText prose slots
-- deterministic labels derived from module outputs, including current
-  conditions, hourly forecast rows, precipitation timing, alerts, SPC outlooks,
-  forecast discussion, SPC discussion, and weather story
-
-Daily, Today, and Tomorrow additionally expose forecast-date labels, ordered
-daypart forecast rows, daily/daypart summaries, planning facts, and a
-multi-paragraph forecast discussion generated-text slot. The ordered daypart
-slice is built in Go so templates do not range over maps.
-
-The Daily template asset uses the same Markdown structure as Tomorrow's
-template and renders from `generatedtext.DailyRenderContext`.
-
-Templates use `text/template` with `missingkey=error`, so missing context fields
-fail rendering instead of producing incomplete Markdown.
-
-Daily and Tomorrow call the shared `daypart_forecast` partial. Today calls
-`today_daypart_forecast` so it can omit elapsed or missing dayparts. Daily,
-Today, Tomorrow, and Hourly call the shared `alert_digest` and
-`precipitation_timing` partials. Partial files are parsed with each top-level
-template at render time and receive the same typed render context as the
-caller. The `alert_digest` partial renders the combined Alerts and Risk
-Products section from relevant NWS alerts and curated SPC outlook digest
-records.
-
-## Schema Contract
-
-The GeneratedText schemas describe the structured prose Scriptorium is expected
-to write for each generated-text prompt. Hourly requires:
-
-- `summary`
-- `forecast_discussion`
-
-Daily, Today, and Tomorrow require `summary` and a nonempty
-`forecast_discussion` array. All generated-text schemas allow optional
-`precipitation_timing` and `confidence`, and reject additional properties.
-Weather truth remains in module outputs; GeneratedText is limited to prose
-slots consumed by the template.
-
-## Failure Behavior
-
-- Unknown template IDs return actionable lookup errors.
-- Unknown schema IDs return actionable lookup errors.
-- Template parse errors include the template ID.
-- Partial read or parse errors include the partial path.

-- captured stdout and stderr
-- truncation flags for captured output
-- exit code
-- report output path for `run`
-- raw generated-text output path for structured `run`
-
-## Boundaries
-
-`internal/adapters/scriptorium` owns Scriptorium command construction and
-subprocess execution. It does not choose report types, build prompt input,
-collect weather data, decide workflow order, or persist workflow metadata.
-
-The adapter exposes request and result structs for render, Markdown run, and
-structured generated-text run operations. State persistence uses state-owned
-artifact shapes; app orchestration converts adapter 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>
-```
-
-Structured generated-text argv uses the same `scriptorium run` form, with the
-`--out` value set to the raw generated-text JSON artifact path. The adapter
-does not add `--format`, schema path, or JSON Schema flags for structured
-generation; Scriptorium selects the structured output schema from prompt
-configuration.
-
-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, Markdown run, and structured 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, Markdown run, and structured 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, Markdown run, and structured 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
-- generated-text raw, run-result, validated text, and render-context artifacts
-- rendered report path preparation request
-- RunID for inspection lookups
-
-Outputs:
-
-- module snapshot JSON path
-- prompt input data package YAML path
-- render preflight JSON path
-- generated-text raw JSON path
-- generated-text run-result JSON path
-- validated generated-text JSON path
-- render context JSON path
-- managed Markdown report path
-- metadata JSON path
-- distributor notification debug artifact paths
-- prior comparable snapshot metadata
-- loaded module snapshot, data package, generated text, generated-text run
-  result, or render context
-- 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, and the RunID. Filenames put the artifact kind before
-the RunID.
-
-```text
-<workspace.root>/
-  reports/<artifact_group>/<YYYY-MM-DD>/report.<run_id>.md
-  snapshots/<artifact_group>/<YYYY-MM-DD>/modules.<run_id>.json
-  snapshots/<artifact_group>/<YYYY-MM-DD>/metadata.<run_id>.json
-  snapshots/<artifact_group>/<YYYY-MM-DD>/generated_text_raw.<run_id>.json
-  snapshots/<artifact_group>/<YYYY-MM-DD>/generated_text_result.<run_id>.json
-  snapshots/<artifact_group>/<YYYY-MM-DD>/generated_text.<run_id>.json
-  snapshots/<artifact_group>/<YYYY-MM-DD>/render_context.<run_id>.json
-  data-packages/<artifact_group>/<YYYY-MM-DD>/data_package.<run_id>.yaml
-  preflight/<artifact_group>/<YYYY-MM-DD>/render.<run_id>.json
-  notifications/<artifact_group>/<YYYY-MM-DD>/distributor.<run_id>.json
-  notifications/batches/<batch>/<YYYY-MM-DD>/distributor.<batch_run_id>.json
-```
-
-Metadata is stored beside module snapshots and links the module snapshot, data
-package, preflight, report paths, notification path when attempted, and
-configured prompt location. For generated-text-template reports, metadata also
-records the generated text schema ID and links the raw generated text,
-Scriptorium run result, validated generated text, and render context artifacts.
-Markdown-report metadata omits those generated-text fields. Report listing
-walks metadata files under the snapshots directory.
-
-Batch notification artifacts are stored under the notifications tree rather
-than report metadata because they describe a batch-level upload. The date
-directory is the batch start date in the effective report timezone.
-
-## 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 Report compares with prior Daily Report snapshots for the same valid
-  local date.
-- Today Report compares with prior Today Report snapshots for the same valid
-  local date.
-- Tomorrow Report compares with prior Tomorrow Report snapshots 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.
-- Hourly Report uses the rolling-window comparison strategy and currently
-  returns no prior snapshot from filesystem lookup.
-- 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. Generated-text raw and
-validated JSON artifacts are written atomically as bytes; generated-text run
-result and render context artifacts are written atomically as JSON. 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.
-
-Single-report notification artifacts use schema version
-`weatherreporter.distributor_notification.v1` and record one managed source
-path plus that source's bundle paths. Batch notification artifacts use schema
-version `weatherreporter.batch_distributor_notification.v1` and record:
-
-- `batch`
-- `batchRunId`
-- `attemptedAt`
-- `endpoint`
-- `pipelineId`
-- `bundleId`
-- `idempotencyKey`
-- `bundleCreated`
-- `includedReports`, each with `reportId`, `runId`, `sourcePath`, and
-  `bundlePaths`
-- `status`
-- `upload`
-- `runStatus`
-- `statusError`
-- `error`
-
-Inspection helpers read existing metadata, module snapshot, data package,
-generated text, generated-text run result, and render context 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.
-- Generated-text artifacts live under the snapshots tree beside module
-  snapshots and metadata.
-- Batch notification artifacts live under `notifications/batches` and are not
-  linked from report metadata.
-- 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

+adapter translates provider responses into these types; its request, response,
+and availability contract is documented in the

-## Purpose
+## Bundle contract
 
-`internal/adapters/weatherapi` fetches normalized weather data from the

-## 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

-## Boundaries
+An empty product can be meaningful checked data. For example, an explicit

+## Warning semantics
 
-- `weather_api.base_url`

-- `weather_api.timeout`
+endpoint, and `CompletenessImpact`. When collection proceeds with a warning,
-- `weather_api.format`

-SPC convective outlook data is stored on

-## Skip And Resume Behavior
-
-No resume behavior. Optional missing or malformed sources may be omitted,

-## Failure Behavior
-

-Batch commands:
+Weatherreporter validates the final output filename before prompt inspection or
+weather collection. A valid long filename is published through a short,
+same-directory temporary sibling, so temporary naming does not shorten the
+operator-selected destination. A rejected filename does not create a missing
+parent directory. The final destination itself must be absent or a regular
+file: symlinks, directories, named pipes, sockets, and other special objects
+are rejected before prompt inspection or weather collection. The destination is
+checked again immediately before the atomic replacement; cancellation or a

-## Filesystem Layout
+For a single report, Distributor notification follows the atomic output write.

-The default workspace root is `workspace`.
+## Comparison Bundles
 
-```text
+Use `compare` when an operator needs to evaluate explicit Promptkit profiles
-workspace/
+against the same report input. The command writes one flat, operator-owned
-  reports/<artifact_group>/<YYYY-MM-DD>/report.<run_id>.md
+bundle directory and never sends a Distributor notification. Command syntax,
+profile validation, JSON output, and exit behavior belong to the
+[CLI reference](cli.md); the durable file contract belongs to the
+[comparison bundle contract](integrations/comparison-bundle.md).
 
-  snapshots/<artifact_group>/<YYYY-MM-DD>/modules.<run_id>.json
+The output destination follows the normal `output.directory` fallback. An
-  snapshots/<artifact_group>/<YYYY-MM-DD>/metadata.<run_id>.json
+explicit `--out-dir` takes precedence and names the exact bundle directory,
-  snapshots/<artifact_group>/<YYYY-MM-DD>/generated_text_raw.<run_id>.json
+not a parent to be combined with another name. The standard names are derived
-  snapshots/<artifact_group>/<YYYY-MM-DD>/generated_text_result.<run_id>.json
+from the report output name, such as `comparison-today` and
-  snapshots/<artifact_group>/<YYYY-MM-DD>/generated_text.<run_id>.json
+`comparison-daily-2026-05-29`; see the [configuration reference](config.md)
-  snapshots/<artifact_group>/<YYYY-MM-DD>/render_context.<run_id>.json
+for output-directory resolution.
 
-  data-packages/<artifact_group>/<YYYY-MM-DD>/data_package.<run_id>.yaml
+A comparison bundle contains the shared data package, a manifest, and one
-  preflight/<artifact_group>/<YYYY-MM-DD>/render.<run_id>.json
+Markdown file for every successful profile. Treat all of these files as
+potentially sensitive: the data package and generated reports can contain
+location or forecast context. Weatherreporter creates no application-owned
+history, retention store, or cleanup job. Retain, archive, or remove only the
+specific bundle directories your operating policy permits.
 
-  notifications/<artifact_group>/<YYYY-MM-DD>/distributor.<run_id>.json
+The destination is preflighted before prompt inspection and collection, then
-  notifications/batches/<batch>/<YYYY-MM-DD>/distributor.<batch_run_id>.json
+rechecked immediately before an atomic publish. A missing or empty directory
+is usable. A nonempty directory can be replaced only when `--replace` is given
+and it is recognized as a current Weatherreporter comparison bundle; ordinary
+directories, symlinks, and unsafe destinations are rejected. Cancellation and
+all failures before publication preserve an existing bundle, including a
+cancellation observed while a replacement is being prepared. If guarded
+restoration cannot complete, the error names the retained sibling bundle for
+manual recovery. Profile failures are different: the command publishes a
+complete partial bundle, with failed profiles represented in the manifest and
+no Markdown file for those profiles.
+Comparison preflight also checks that private publication siblings can be
+formed. An infeasible destination name is rejected before a missing parent
+directory is created.
+
+## 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
 ```

+operators and remove the captures when they are no longer needed. Comparison
+captures additionally identify each selected profile so concurrent executions
+remain distinct. Normal output, summaries, and routine logs omit that sensitive
+content. Debug capture is never created for an ordinary command without
+`--llm-debug-dir`.

-20260529T100000.123456789Z_daily_2026-05-31
+filesystem component prevents secure artifact creation.
-20260529T100000.123456789Z_today
+
+If capture creation or writing fails, the affected run fails rather than
+silently continuing without the requested diagnostics.
+
+## Diagnosing Failures
+
+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. For a comparison
+failure, inspect the published manifest when its path is present: individual
+profile failures retain their safe result and successful Markdown files, while
+cancellation and pre-publication errors leave the prior destination unchanged.
+
+If a replacement commits but cleanup of its prior sibling backup fails, the new
+bundle remains valid and its artifact paths appear in the failed command
+summary. The summary records a safe `publication_cleanup` error that indicates
+whether a complete prior bundle remains, only partial remnants remain, or no
+prior bundle remains; it also identifies when the sibling cannot be inspected.
+The returned command error includes a recovery path only when a sibling remains.
+Preserve a complete recognized recovery bundle until it has been inspected and
+cleaned up manually; partial remnants are not a rollback artifact. Do not
+remove the new bundle to retry cleanup.
+
+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
 ```
 
-Batch notification RunIDs use the batch start timestamp plus the batch command
+This removal cannot be recovered by Weatherreporter. Keep or archive any
-name:
+historical files that are still needed before deleting them.

-
-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
-- generated text schema ID and generated-text artifact paths for
-  generated-text-template reports
-- distributor notification debug artifact path, when notification is attempted
-
-Batch summaries include report status, error text when applicable, valid
-period, and known artifact paths for each attempted report. Single-report
-notification fields on report items are empty for batch commands. When a batch
-notification is attempted, skipped, or fails, the summary includes one
-top-level `notification` object with fields such as `status`, `reason`,
-`runId`, `pipelineId`, `bundleId`, `idempotencyKey`, `path`,
-`includedReports`, and `error`.
-
-## Distributor Notification
-
-Distributor notification is configured with `notify.distributor` and is
-disabled by default. For `generate <report>`, weatherreporter uploads the
-managed Markdown report path recorded in the report result and metadata. That
-single source file is mapped to report-specific bundle paths. Extra copies
-written by `--out` or `--out-dir` are operator conveniences only.
-
-For `run morning` and `run evening`, per-report notification is suppressed. If
-`notify.distributor.enabled` and `notify.distributor.batch.enabled` are both
-true, the batch uploads once after all reports finish successfully. The upload
-contains one file mapping set per included report. Each mapping uses the
-managed Markdown report as the source and report-specific path templates for
-that report. All rendered bundle paths across the batch must be unique. If any
-report fails, weatherreporter records a top-level
-notification status of `skipped` with reason `one or more reports failed` and
-does not call distributor. If batch notification is disabled, run commands do
-not fall back to per-report uploads.
-
-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 single-report 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. Batch bundle
-IDs default to `weatherreporter.{location_id}.{batch}`, and batch idempotency
-keys default to `{bundle_id}.{batch_run_id}`. Distributor owns destination
-merge, retention, and derived snapshot behavior such as `latest`. For Daily,
-the default report ID and artifact group values are both `daily`, and the
-default output filename value is `daily.md`. For Today, the default report ID
-and artifact group values are both `today`, and the batch output filename value
-is `today.md`.
-
-Single-report notification happens after final metadata save for generated
-reports. Batch notification happens after all planned reports have finished and
-only when all report generations succeeded. Collection, module snapshot,
-data-package, render preflight, Scriptorium run, generated-text validation,
-template rendering, and metadata-save failures do not trigger notification. A
-single-report notification failure fails that report. A batch notification
-failure makes the batch return nonzero and increments the aggregate failure
-count, but individual report items remain succeeded.
-
-Each notification attempt writes a debug artifact under `notifications/`.
-Single-report artifacts live under
-`notifications/<artifact_group>/<YYYY-MM-DD>/distributor.<run_id>.json`. Batch
-artifacts live under
-`notifications/batches/<batch>/<YYYY-MM-DD>/distributor.<batch_run_id>.json`,
-where the date directory is the batch start date in the effective report
-timezone. The artifact records the rendered pipeline ID, bundle ID,
-idempotency key, managed source paths, 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 collect 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 with rich
-template-facing values, and `inspect data-package` to review the curated prompt
-package passed to Scriptorium. 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 Report compares with prior Daily Report snapshots for the same valid
-local date. Today Report compares with prior Today Report snapshots for the
-same valid local date. Tomorrow Report compares with prior Tomorrow Report
-snapshots for 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.
-Hourly Report and Storm Report leave 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.
-- Generated-text failures for Daily, Today, Tomorrow, and Hourly reports preserve
-  available intermediate artifacts, such as the structured run result, raw
-  generated-text JSON, validated generated text, and render context. Metadata
-  links those paths when it can be safely written.
-- If single-report distributor notification fails, report artifacts and final
-  metadata remain available, but the report command returns nonzero.
-- If batch distributor notification fails, report artifacts and final metadata
-  remain available, the top-level batch notification links the debug artifact,
-  and the batch command returns nonzero.
-- For batch commands, inspect the stdout JSON summary first, then inspect the
-  artifact paths for each failed report or the top-level notification path.
-
-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.

-# Architecture
+# Architecture Policy
 
-This document defines the development principles for this Go project. It is inward-facing: developers and LLM coding agents should use it to preserve the project’s shape, boundaries, and invariants as the code evolves.
+## Purpose
 
-## weatherreporter
+This policy defines Weatherreporter's system shape, ownership, dependency direction,
-`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.
+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.
+An explicit profile comparison prepares one report input once, executes the
+same exact prompt and data package across selected profiles concurrently, and
+atomically publishes one operator-owned comparison bundle. It remains local:
+it does not create application state or send a Distributor notification.
 
-`scriptorium` is an external adapter, not domain logic. Subprocess execution must be isolated under `internal/adapters/scriptorium`, use context-aware execution, avoid shell interpolation, capture actionable stderr, and keep scriptorium-specific flags from leaking into domain packages.
+The 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.
 
-`distributor` is also an external adapter. Upload behavior must be isolated
+## Ownership And Boundaries
-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.
 
-## Project Shape
+- `internal/cli` owns command parsing, help, summaries, and one executor
+  construction per action.
+- `internal/config` owns defaults, loading, validation, and secret loading.
+- `internal/app` owns in-memory workflow order, partial results, atomic output
+  publication, and notification coordination through project-owned contracts.
+- `internal/comparison` owns comparison identity, durable logical bundle
+  validation, safe destination recognition, and atomic bundle publication.
+- 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.
 
-Default to a small, explicit, dependency-light Go application. Keep the design modular enough to test and change safely, but do not add abstraction unless it protects a real boundary or enables a real extension point.
+Dependency-specific Promptkit types remain inside its adapter. The application
+does not parse flags, construct provider clients, or render provider output
+directly.
 
-Business/domain logic should live outside CLI, transport, and external-adapter packages.
+## Prompt Execution Invariants
 
-## Dependency Policy
+- Prompts receive curated module packages, never unbounded raw weather payloads.
+- Every execution 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.
+- Comparison validates every explicit profile before collection, prepares one
+  immutable report input, and delegates backend capacity to Promptkit rather
+  than adding an application-wide execution limit.
+- 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.
 
-Prefer the Go standard library where practical.
+## Output, Notification, And Testing Invariants
 
-Use external dependencies only when justified by correctness, security, interoperability, or substantial complexity reduction. Good reasons include complex security-sensitive behavior, such as HTML sanitization, or widely used de facto standards, such as YAML parsing.
+- 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.
+- A single-report final destination is either absent or a regular file.
+  Symlinks and special filesystem objects are rejected during preflight and
+  rechecked immediately before the atomic replacement.
+- Configuration or explicit CLI input selects that operator-owned destination;
+  it does not create an application-owned state boundary.
+- Comparison bundles are flat, versioned operator outputs. Their guarded
+  replacement accepts only a recognized current bundle; cancellation and every
+  pre-publication failure preserve a prior bundle, while individual profile
+  failures can publish a complete partial bundle.
+- 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.
+- Comparison never invokes Distributor notification.
+- Profile comparison supports operator review only: it does not score, rank,
+  select, resample, or replay profile executions.
+- Default tests are deterministic, offline, and use Promptkit/provider fakes
+  rather than live provider calls. See the [testing policy](testing.md).
 
-Avoid dependencies for small conveniences. Do not let external dependency types leak across internal package boundaries unless the dependency is itself the explicit public contract of that package.
+## Non-Goals
 
-## Package Layout
+Weatherreporter is not a weather-data ingestion service, general LLM
-
+orchestration framework, plugin platform, HTTP service, multi-user job system,
-Use this layout unless the project has a documented reason to differ:
+or a replacement for Promptkit or Distributor.
-
-- `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.

-
-## 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;
-- declare whether the command is an action command or an inspection/data-output
-  command;
-- convert parsed values into app-layer request structs;
-- keep domain decisions in `internal/app` or domain packages;
-- use the centralized output helpers in `internal/cli/output.go`;
-- keep action-command summary conversion in `internal/cli/result.go`;
-- 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.

+owner. Its goal is to keep documentation accurate, concise, discoverable, and
-1. users who need to run the application;
+resistant to drift for users, operators, developers, integrators, maintainers,
-2. administrators/operators who need to configure and operate it;
+and coding agents.
-3. developers who need to understand and change it safely;
-4. LLM coding agents that need clear scope, boundaries, and invariants.
-
-Docs should be accurate, concise, task-oriented, and organized by audience. Prefer links to canonical docs over repetition.
 
 ## Core Rules
 
-### 1. Keep docs concise
+### One Canonical Documentation Owner
-
+
-Each document should cover a defined scope and only the essentials for that scope.
+Each authoritative fact belongs in one canonical document or documentation
-
+area. A non-owning document may give a short, stable summary for orientation,
-Avoid:
+but it must link to the canonical owner instead of maintaining a second
-- long background explanations;
+definition.
-- repeated reference material;
+
-- implementation detail in user-facing docs;
+Volatile details include commands, flags, configuration fields and defaults,
-- aspirational language outside roadmap docs;
+report and module IDs, schemas, file names, paths, status and exit behavior,
-- verbose examples where one minimal example is clearer.
+retry behavior, and runtime guarantees. If readers could reasonably treat a
-
+statement as a contract, its exact documentation belongs with the owner named
-### 2. Document only implemented behavior outside roadmap files
+in this policy.
-
+
-Unimplemented, planned, aspirational, experimental, or future work may be described only under:
+Executable sources of truth and documentation owners serve different purposes.
-
+Code, schemas, and embedded assets determine runtime behavior. The canonical
-- `docs/roadmap/`
+document owns the corresponding explanation or reference for readers. Both may
-
+necessarily express the same contract, but other documentation should summarize
-No other documentation file, including `README.md`, should describe code, features, modules, stages, commands, config fields, or behaviors that do not currently exist.
+and link rather than create another complete reference. When implementation and
-
+documentation disagree, verify the intended behavior and update them together.
-If a feature is partial, non-roadmap docs may describe only the implemented portion and its current boundary.
+
-
+### Current State, Decisions, And Future Work
-### 3. Use canonical homes
+
-
+Outside `docs/roadmap/`, documentation describes implemented behavior only.
-Each type of information should have one canonical location.
+Partial features may be described only to their implemented boundary.
-
+
-Canonical homes:
+An accepted architecture decision may describe an approved direction before it
-
+is implemented, but acceptance is not evidence that the behavior exists.

+Current-state documents change when the implementation lands. Temporary

+external contracts instead of restating them.
-
+
-Other files should summarize briefly and link to the canonical source.
+### Links
-
+
-### 4. Keep examples real
+Use descriptive link text and repository-relative links for repository
-
+documents. Link to the canonical owner rather than to a duplicate summary.
-Examples should be valid, maintained, and free of secrets.
+Check every added or changed link, and repair or remove links when their target
-
+moves or is retired.
-Where practical:
+
-- example configs should load successfully;
+### Examples And Code Fences
-- example commands should match real CLI syntax;
+
-- important examples should be covered by tests.
+Complete copyable files belong in `examples/` when maintained examples exist.

+including diagnosis, explicit debug capture, and safe legacy cleanup.
-## Required Documents
+
-
+When a workflow crosses these topics, place the complete procedure with the

-Document secret-handling mechanisms, not actual secret values.
-
-## Maintenance Rules
-
-When docs change, verify the affected behavior.
-
-Where practical:
-
-- load example config files in tests;
-- test CLI examples or command parser behavior;
-- validate documented flags against real flags;
-- remove stale references;
-- update links after renames;
-- keep roadmap content out of non-roadmap docs.
-
-If documentation and code disagree, fix the documentation and/or open a roadmap item; do not leave aspirational behavior in current-behavior docs.
-
-Documentation is complete only when it matches the current code.
-
-## Documentation Change Checklist
-
-Before merging documentation changes, verify:
-
-- README is concise and orientation-focused.
-- `docs/policy/architecture.md` describes development principles.
-- Future work appears only under `docs/roadmap/`.
-- User-facing docs avoid unnecessary internals.
-- Developer-facing docs preserve boundaries and invariants.

+# 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 v0.12.0
+
+This release completes a repository-wide correctness, security, efficiency,
+test-durability, and documentation audit.
+
+## Summary
+
+Weatherreporter now applies stricter validation and bounded diagnostics across
+its configuration, weather collection, Promptkit, rendering, publication,
+comparison, and Distributor boundaries. Report preparation and execution carry
+one reconciled identity, independent weather sources are collected
+concurrently, and cancellation preserves completed report and comparison
+outcomes.
+
+The release also removes obsolete compatibility surfaces and consolidates
+duplicated implementation and test policy without changing ordinary report
+commands or output identities.
+
+## Compatibility
+
+This release is compatible with `v0.11.0` for ordinary `generate`, `run`, and
+`compare` commands, configuration files, report filenames, comparison bundles,
+and Distributor integration.
+
+Sensitive prompt-debug capture through `--llm-debug-dir` is now supported only
+on Unix hosts. Non-Unix hosts reject an explicit capture request before prompt
+inspection, weather collection, or provider execution because the required
+handle-relative, no-follow filesystem guarantees are unavailable there.
+
+Several unused internal compatibility exports were removed. They were not part
+of the documented CLI, configuration, artifact, or integration contracts.
+
+## Upgrade
+
+No special action is required for ordinary installations. Operators who use
+`--llm-debug-dir` on Windows must run that diagnostic workflow on a Unix host.
+Review any automation that depended on undocumented internal Go APIs removed by
+this release.
+
+## Changes
+
+- Hardened configuration loading, source validation, secrets rollback,
+  endpoint validation, HTTP diagnostics, generated-text limits, prompt-debug
+  redaction, output publication, comparison replacement, and Distributor
+  failure reporting.
+- Reconciled inspected, prepared, callback, and completed Promptkit identity
+  and provenance before accepting generated content.
+- Preserved metric values, civil-day and daypart identity, overnight alerts,
+  precipitation semantics, and Markdown structure across deterministic report
+  preparation and rendering.
+- Collected independent Weather API sources concurrently and reused readiness
+  data while retaining deterministic normalized results.
+- Preserved completed report and comparison failures independently from shared
+  cancellation, stopped unfinished work, and skipped batch notification after
+  cancellation or partial report failure.
+- Made secure prompt-debug traversal descriptor-relative on Unix and fail
+  closed elsewhere. See the [operations
+  guide](../operations.md#optional-prompt-debug-capture).
+- Strengthened default test portability and determinism, including
+  capability-aware symbolic-link fixtures and platform-appropriate process
+  signal coverage.
+- Removed obsolete compatibility helpers, duplicated test ownership, dormant

+# 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.

+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.

-Shared named partials live under `internal/reporttemplate/templates/partials/`:

+  explicit no-details fallback.
 
-## Hourly Context
+Minimal optional-value pattern:
-
-The hourly template receives five top-level values:
-
-| Variable | Type | Description |
-| --- | --- | --- |
-| `.Report` | HourlyReportContext | Display metadata and friendly labels for the rendered report. |
-| `.GeneratedText` | Hourly | Structured text returned by Scriptorium. |
-| `.Modules` | HourlyTemplateModules | Preferred deterministic template surface, keyed by module purpose. |
-| `.Collected` | facts.CollectedFacts | Normalized upstream facts for advanced template use. |
-| `.Derived` | facts.DerivedFacts | Shared derived facts for advanced template use. |
-
-Prefer `.Modules` for normal template edits. `.Collected` and `.Derived` are
-available when a template needs lower-level facts, but templates should still
-avoid nontrivial derivation.
-
-## Report
-
-| Variable | Type | Description |
-| --- | --- | --- |
-| `.Report.Title` | string | Display title. Currently `Hourly Report`. |
-| `.Report.LocationName` | string | Prompt/report location label, such as `Brentwood, MO`. |
-| `.Report.GeneratedAt` | time.Time | Canonical generation timestamp. |
-| `.Report.GeneratedAtLabel` | string | Friendly local generation time label. |
-| `.Report.ValidPeriod` | timeutil.Period | Canonical valid period. |
-| `.Report.ValidPeriodLabel` | string | Friendly local valid period label, such as `2026-05-29 at 8:30 AM to 2026-05-29 at 2:30 PM`. |
-| `.Report.Timezone` | string | Effective report timezone. |
-
-## GeneratedText
-
-These fields are written by Scriptorium as structured JSON, validated by
-weatherreporter, and then inserted into the render context.
-
-| Variable | Type | Description |
-| --- | --- | --- |
-| `.GeneratedText.Summary` | string | Required short prose summary. |
-| `.GeneratedText.ForecastDiscussion` | string | Required prose for the Forecast Discussion section. |
-| `.GeneratedText.PrecipitationTiming` | string | Optional prose rendered after deterministic precipitation windows. |
-| `.GeneratedText.Confidence` | string | Optional confidence or uncertainty note. Empty when omitted by the LLM; not rendered by the current hourly template. |
-
-Example:
-
-```gotemplate
-{{ .GeneratedText.Summary }}
-
-## Forecast Discussion
-
-{{ .GeneratedText.ForecastDiscussion }}
-```
-
-## Tomorrow Context
-
-The Tomorrow template receives five top-level values:

-| Variable | Type | Description |
-| --- | --- | --- |
-| `.Report` | TomorrowReportContext | Display metadata and friendly labels for the rendered report. |
-| `.GeneratedText` | Tomorrow | Structured text returned by Scriptorium. |
-| `.Modules` | TomorrowTemplateModules | Preferred deterministic template surface, keyed by module purpose. |
-| `.Collected` | facts.CollectedFacts | Normalized upstream facts for advanced template use. |
-| `.Derived` | facts.DerivedFacts | Shared derived facts for advanced template use. |
-
-Tomorrow report metadata includes `.Report.Title`, `.Report.ForecastDate`,
-`.Report.ForecastDateLabel`, `.Report.ForecastDayName`,
-`.Report.GeneratedAt`, `.Report.GeneratedAtLabel`, `.Report.ValidPeriod`, and
-`.Report.Timezone`.
-
-Tomorrow generated text uses the same `.GeneratedText.Summary`,
-`.GeneratedText.PrecipitationTiming`, and `.GeneratedText.Confidence` fields as
-Hourly. `.GeneratedText.ForecastDiscussion` is a slice of paragraphs and should
-be rendered with `range`.
-
-Tomorrow uses the shared `alert_digest`, `daypart_forecast`, and
-`precipitation_timing` partials.
-
-Tomorrow modules include the Hourly module fields plus:
-
-| Variable | Type | Description |
-| --- | --- | --- |
-| `.Modules.DerivedDailySummary` | *briefing.DerivedDailySummaryModule | Daily summary facts for the forecast date. |
-| `.Modules.DerivedDaypartSummaries` | *map[string]briefing.DerivedDaypartSummaryModule | Raw daypart summary map, when direct keyed access is needed. |
-| `.Modules.Dayparts` | []generatedtext.TomorrowDaypartContext | Ordered daypart summaries for deterministic template rendering. |
-| `.Modules.TomorrowPlanning` | *briefing.TomorrowPlanningModule | Planning facts for the next local civil day. |
-
-Prefer `.Modules.Dayparts` over ranging through
-`.Modules.DerivedDaypartSummaries`; it follows configured daypart order and
-falls back to sorted keys for any unmatched entries.
-
-## Daily Context
-
-The Daily template receives the same five top-level values as Tomorrow, using
-`DailyReportContext`, `Daily`, and `DailyTemplateModules`.
-
-Daily report metadata includes `.Report.Title`, `.Report.ForecastDate`,
-`.Report.ForecastDateLabel`, `.Report.ForecastDayName`,
-`.Report.GeneratedAt`, `.Report.GeneratedAtLabel`, `.Report.ValidPeriod`, and
-`.Report.Timezone`.
-
-Daily generated text uses `.GeneratedText.Summary`,
-`.GeneratedText.ForecastDiscussion`, `.GeneratedText.PrecipitationTiming`, and
-`.GeneratedText.Confidence`. Forecast discussion is a slice of paragraphs and
-should be rendered with `range`.
-
-Daily uses the shared `alert_digest`, `daypart_forecast`, and
-`precipitation_timing` partials.
-
-Daily uses template ID `daily`, generated-text schema ID `daily`, and prompt
-source `internal/reporttemplate/prompts/daily.generated_text.md`.
-
-Daily modules include the Hourly module fields plus:
-
-| Variable | Type | Description |

-| `.Modules.DerivedDailySummary` | *briefing.DerivedDailySummaryModule | Daily summary facts for the forecast date. |
-| `.Modules.DerivedDaypartSummaries` | *map[string]briefing.DerivedDaypartSummaryModule | Raw daypart summary map, when direct keyed access is needed. |
-| `.Modules.Dayparts` | []generatedtext.DailyDaypartContext | Ordered daypart summaries for deterministic template rendering. |
-| `.Modules.DailyPlanning` | *briefing.DailyPlanningModule | Planning facts for the selected local civil day. |
-
-Prefer `.Modules.Dayparts` over ranging through
-`.Modules.DerivedDaypartSummaries`; it follows configured daypart order and
-falls back to sorted keys for any unmatched entries.
-
-## Today Context
-
-The Today template receives the same five top-level values as Tomorrow, using
-`TodayReportContext`, `Today`, and `TodayTemplateModules`.
-
-Today report metadata includes `.Report.Title`, `.Report.ForecastDate`,
-`.Report.ForecastDateLabel`, `.Report.ForecastDayName`,
-`.Report.GeneratedAt`, `.Report.GeneratedAtLabel`, `.Report.ValidPeriod`, and
-`.Report.Timezone`.
-
-Today generated text uses `.GeneratedText.Summary`,
-`.GeneratedText.ForecastDiscussion`, `.GeneratedText.PrecipitationTiming`, and
-`.GeneratedText.Confidence`. Forecast discussion is a slice of paragraphs and
-should be rendered with `range`.
-
-Today uses the `today_daypart_forecast` partial so elapsed or missing dayparts
-can be omitted while Daily and Tomorrow keep their fallback row. It also uses
-the shared `alert_digest` and `precipitation_timing` partials.
-
-Today uses template ID `today`, generated-text schema ID `today`, and prompt
-source `internal/reporttemplate/prompts/today.generated_text.md`.
-
-Today modules include the Hourly module fields plus:
-
-| Variable | Type | Description |

-| `.Modules.DerivedDailySummary` | *briefing.DerivedDailySummaryModule | Daily summary facts for the forecast date. |
-| `.Modules.DerivedDaypartSummaries` | *map[string]briefing.DerivedDaypartSummaryModule | Raw daypart summary map, when direct keyed access is needed. |
-| `.Modules.Dayparts` | []generatedtext.TodayDaypartContext | Ordered daypart summaries for deterministic template rendering. |
-| `.Modules.TodayPlanning` | *briefing.TodayPlanningModule | Planning facts for the current local civil day. |
-
-Prefer `.Modules.Dayparts` over ranging through
-`.Modules.DerivedDaypartSummaries`; it follows configured daypart order and
-falls back to sorted keys for any unmatched entries.
-
-## Modules
-
-`.Modules` exposes typed outputs from the same module pipeline used for the
-prompt data package. Module fields are pointers because missing-data policy may
-omit a stanza.
-
-Templates render from rich module values, not from the curated YAML data
-package. Some fields documented below are deterministic wording helpers for
-Markdown templates and are intentionally omitted from data packages passed to
-Scriptorium. The data package is a prompt input, while the render context is the
-template surface.
-
-| Variable | Type | Description |
-| --- | --- | --- |
-| `.Modules.Metadata` | *briefing.MetadataModule | Report metadata module output, when present. |
-| `.Modules.CurrentConditions` | *briefing.CurrentConditionsModule | Current conditions from `/conditions/current`. |
-| `.Modules.HourlyForecast` | *briefing.HourlyForecastModule | Hourly forecast periods overlapping the report valid period. |
-| `.Modules.PrecipTiming` | *briefing.PrecipTimingModule | Derived precipitation timing facts and threshold windows. |
-| `.Modules.AlertDigest` | *briefing.AlertDigestModule | Active alert status and relevant alert overlaps. |
-| `.Modules.SPCConvectiveOutlooks` | *briefing.SPCConvectiveOutlooksModule | SPC outlooks that overlap the report valid period. |
-| `.Modules.AreaForecastDiscussion` | *briefing.AreaForecastDiscussionModule | AFD key messages and configured discussion sections. |
-| `.Modules.SPCConvectiveDiscussion` | *briefing.SPCConvectiveDiscussionModule | SPC discussions retained for qualifying overlapping categorical risk days. |
-| `.Modules.WeatherStory` | *briefing.WeatherStoryModule | Latest NWS weather story, when available. |
-
-### Current Conditions
-
-Common fields:
-
-| Variable | Type | Description |
-| --- | --- | --- |
-| `.Modules.CurrentConditions.ConditionText` | string | Current condition text. |
-| `.Modules.CurrentConditions.ConditionTextLower` | string | Lower-case current condition text for inline sentences. |
-| `.Modules.CurrentConditions.TemperatureF` | *int | Rounded current temperature. |
-| `.Modules.CurrentConditions.ApparentTemperatureF` | *int | Rounded apparent temperature. |
-| `.Modules.CurrentConditions.RelativeHumidityPercent` | *int | Rounded relative humidity. |
-| `.Modules.CurrentConditions.WindDirection` | string | 16-point compass wind direction. |

+{{ plainText . }}
-{{ else }}
+{{ end }}
-- No hourly forecast rows available.
-{{ end }}{{ end }}
 ```
 
-### Precipitation Timing
+## Registered Functions
 
-Common fields:
+Templates have these helpers in addition to Go template built-ins:

-### Daypart Summaries
+For example, the alert partial uses the first two functions to decide whether
+to render the section:
 
-Daily, Today, and Tomorrow templates should use `.Modules.Dayparts` for
+```gotemplate
-ordered daypart rendering. Each item has `Key` and `Summary`; `Summary` is a
+{{ if hasRelevantAlerts .Modules.AlertDigest }}
-rich `briefing.DerivedDaypartSummaryModule`.
+## Alert Digest
+{{ end }}
+```
 
-The shared daypart partials render from these same `.Modules.Dayparts` values.
+## Render Context
-Edit `daypart_forecast.md.tmpl` for common Daily/Tomorrow wording, and edit
-`today_daypart_forecast.md.tmpl` for Today-specific omission behavior.
 
-Common rich daypart fields:
+Every rendered template receives one typed context with these three top-level
+fields:
 
-| Variable | Type | Description |
+| Field | Purpose |

-### Area Forecast Discussion
+GeneratedText is prose returned by Promptkit and validated before rendering.
+It is not a source for deterministic weather facts.
 
-| Variable | Type | Description |
+| Field | Hourly type | Daily, Today, and Tomorrow type | Notes |
-| --- | --- | --- |
+| --- | --- | --- | --- |
-| `.Modules.AreaForecastDiscussion.Product` | string | Source product identifier. |
+| `.GeneratedText.Summary` | `string` | `string` | Required; at most 4,000 characters. |
-| `.Modules.AreaForecastDiscussion.KeyMessages` | []string | AFD key messages. |
+| `.GeneratedText.ForecastDiscussion` | `string` | `[]string` | Required; Hourly permits 12,000 characters. Day-style values permit up to 12 paragraphs of 4,000 characters each. |
-| `.Modules.AreaForecastDiscussion.ShortTerm` | string | AFD short-term section text. |
+| `.GeneratedText.PrecipitationTiming` | `string` | `string` | Required field, at most 4,000 characters; an empty string represents no supported prose. The precipitation partial uses nonempty prose only when deterministic windows exist. |
-| `.Modules.AreaForecastDiscussion.LongTerm` | string | AFD long-term section text. |
 
-### Weather Story
+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). All validated generated prose together
+is limited to 20,000 characters, so template edits can rely on a bounded prose
+surface.
 
-| Variable | Type | Description |
+### Deterministic Module Values
-| --- | --- | --- |
-| `.Modules.WeatherStory.Available` | bool | True when a story is available. |
-| `.Modules.WeatherStory.OfficeID` | string | Source office ID. |
-| `.Modules.WeatherStory.PeriodBegins` | string | Friendly story period start. |
-| `.Modules.WeatherStory.PeriodEnds` | string | Friendly story period end. |
-| `.Modules.WeatherStory.UpdatedAt` | *time.Time | Canonical update timestamp. |
-| `.Modules.WeatherStory.Title` | string | Story title. |
-| `.Modules.WeatherStory.Description` | string | Story description. |
-| `.Modules.WeatherStory.AltText` | string | Story image alt text. |
-| `.Modules.WeatherStory.Priority` | bool | Source priority flag. |
-| `.Modules.WeatherStory.Order` | int | Source order. |
-| `.Modules.WeatherStory.DownloadURL` | string | Source download URL. |
 
-## Collected And Derived Facts
+Module values are deterministic outputs built from collected and derived facts.
+Module pointers can be nil when their source or policy permits omission.
 
-The template also receives the full `facts.CollectedFacts` and
+| Module field | Available in |
-`facts.DerivedFacts` structs:
+| --- | --- |
+| `.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.HasDaypartDetails` | Today |
+| `.Modules.OutdoorWindows`, `.Modules.DailyPlanning` | Daily |
+| `.Modules.TodayPlanning` | Today |
+| `.Modules.TomorrowPlanning` | Tomorrow |
 
-- `.Collected` contains normalized source data and provenance from upstream
+The repository templates currently use the following nested display values.
-  Weather API fetches.
+They are the preferred surface for comparable edits:
-- `.Derived` contains shared slices and calculations used across modules, such
-  as valid-period hourly periods, precipitation timing, alert overlaps, and SPC
-  filtering inputs.
 
-These values are intentionally lower-level than `.Modules`. Use them when a
+| Area | Values |
-template needs a specific field that is not exposed by a module, but keep
+| --- | --- |
-calculation-heavy changes in Go.
+| 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` |
 
-## Validation
+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).
 
-After editing a template, run:
+## Validate Changes
 
-```bash
+Run the focused checks after editing templates, partials, prompts, or schemas:
+
+```sh
 go test ./internal/reporttemplate ./internal/generatedtext ./internal/app
-```
-
-For a full check, run:
-
-```bash
-go test ./...
-go run ./cmd/weatherreporter --help
 git diff --check
 ```
 
-Template render tests exercise the Daily, Today, Tomorrow, and Hourly
+The render-context and template tests cover Daily, Today, Tomorrow, and Hourly
-templates through `internal/generatedtext/render_context_test.go` and
+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 collecting 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).
-
-## Generated Text Validation Fails
-
-Symptom: Daily, Today, Tomorrow, or Hourly generation fails with generated-text
-decode, unknown-field, required-field, or multiple-JSON-values context.
-
-Likely cause: Scriptorium wrote structured JSON that does not match the
-GeneratedText contract for the selected report.
-
-Diagnostic:
-
-```sh
-weatherreporter inspect metadata RUN_ID
-```
-
-Then inspect the generated-text raw path recorded in metadata, if present.
-
-Safe fix: update the Scriptorium prompt or schema configuration so the prompt
-writes the expected structured JSON for the report.
-
-Relevant docs: [Operations guide](operations.md),
-[Generated Text internals](internal/generatedtext.md),
-[Scriptorium integration](integrations/scriptorium.md).
-
-## Template Rendering Fails
-
-Symptom: Daily, Today, Tomorrow, or Hourly generation fails with report template
-parsing or execution context after generated text validation succeeds.
-
-Likely cause: an embedded template references a missing context field or
-receives a value shape that does not match its typed render context.
-
-Diagnostic:
-
-```sh
-weatherreporter inspect metadata RUN_ID
-```
-
-If metadata records generated-text and render-context paths, inspect those
-artifacts along with the template named by the report definition.
-
-Safe fix: update the embedded template or render-context builder so the
-template uses the implemented typed context.
-
-Relevant docs: [Report Templates](templates.md),
-[Report Template internals](internal/reporttemplate.md).
-
-## Batch Command Returns Nonzero
-
-Symptom: `run morning` or `run evening` returns nonzero.
-
-Likely cause: weather collection failed before planning, or at least one
-planned report failed after planning succeeded, or every report succeeded but
-the top-level batch distributor notification failed.
-
-Diagnostic: if stdout contains a JSON summary, inspect each failed report item
-and the top-level `notification` object. Stderr includes one
-`batchNotification` line when batch notification is attempted, skipped, or
-fails. If no summary was emitted, inspect the command error; configuration,
-Weather API collection, or batch validation failed before any report artifacts
-were created.
-
-Safe fix: for collection failures, fix the configuration or upstream Weather
-API availability and rerun the batch. For report failures, use the failed
-report's artifact paths from the summary, then inspect metadata, sources,
-module snapshot, and data package for that RunID. For a batch notification
-failure, inspect the notification artifact path from the top-level
-`notification.path`.
-
-Relevant docs: [CLI reference](cli.md), [Operations guide](operations.md).
-
-## Batch Upload Skipped
-
-Symptom: a batch JSON summary contains
-`"notification":{"status":"skipped","reason":"one or more reports failed"}`.
-
-Likely cause: at least one planned report failed, so weatherreporter did not
-call distributor for the batch.
-
-Diagnostic: inspect the failed report items in the batch JSON summary and the
-matching stderr report lines. A skipped batch notification has no distributor
-run ID and no notification artifact path.
-
-Safe fix: fix the report-generation failure first, then rerun the batch. The
-batch upload is all-or-nothing.
-
-Relevant docs: [Operations guide](operations.md).
-
-## Batch Upload Fails
-
-Symptom: every report item in a batch summary is succeeded, but the batch
-returns nonzero and the top-level notification has `status: "failed"`.
-
-Likely cause: the distributor upload was rejected, the distributor service was
-unavailable, status polling reached a terminal distributor failure, or
-weatherreporter rejected the batch file mapping before upload.
-
-Diagnostic: inspect `notification.error`, `notification.pipelineId`,
-`notification.bundleId`, `notification.idempotencyKey`, and
-`notification.path` in stdout. Then inspect the notification artifact; it
-records included report source paths, bundle paths, upload status, distributor
-run status, status lookup error, and raw status report JSON when available.
-
-Safe fix: fix the endpoint, token, distributor pipeline, batch identity
-templates, or report path templates indicated by the error, then rerun the
-batch. Individual report artifacts from the failed batch notification remain
-available and do not need to be regenerated for diagnosis.
-
-Relevant docs: [Configuration reference](config.md),
-[Operations guide](operations.md).
-
-## Duplicate Batch Bundle Path
-
-Symptom: a batch returns nonzero with duplicate bundle path context before a
-distributor run ID is accepted.
-
-Likely cause: report-specific distributor path templates rendered the same
-bundle-relative path for two included reports in the same batch.
-
-Diagnostic: inspect the error in stdout or stderr. The validation error
-includes the duplicate bundle path plus the report IDs, RunIDs, and managed
-source paths involved.
-
-Safe fix: configure a per-report distributor path override so every report in a
-batch renders a unique path. Include values such as `{artifact_group}`,
-`{valid_start_date}`, `{batch_output_name}`, or `{run_id}` when needed.
-
-Relevant docs: [Configuration reference](config.md),
-[Operations guide](operations.md).
-
-## Distributor Source Conflict
-
-Symptom: distributor accepts or rejects an upload with conflict context for a
-source, destination, digest, or idempotency key.
-
-Likely cause: the rendered bundle ID or idempotency key does not match the
-intended producer identity. A bundle ID identifies the logical source stream;
-an idempotency key identifies a retry of the same upload request.
-
-Diagnostic: inspect the report notification artifact linked from metadata or
-the batch notification artifact linked from the top-level notification path.
-Compare the rendered pipeline ID, bundle ID, idempotency key, included source
-paths, and bundle paths with `notify.distributor.*` templates and distributor
-pipeline state.
-
-Safe fix: keep bundle ID templates stable for the source stream that should be
-updated, and keep idempotency keys stable only for retries of the same generated
-content. Do not reuse one idempotency key for different report or batch
-content.
-
-Relevant docs: [Operations guide](operations.md),
-[Distributor adapter internals](internal/distributor-adapter.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. For batch commands, use the top-level notification
-object rather than per-report notification fields. Compare the configured
-templates with the report RunID or batch RunID and report path.
-
-Also inspect the notification artifact linked from metadata or from the
-top-level batch notification path. 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` or the top-level batch notification `error`. Confirm
-`notify.distributor.endpoint`,
-`notify.distributor.pipeline_id_template`,
-report-specific distributor paths, 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 the top-level
-notification object and the artifact linked by `notification.path`.
-
-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).
