+# Distributor Adapter Internals
+
+This document describes the distributor upload adapter in
+`internal/adapters/distributor`.
+
+## Purpose
+
+The adapter submits generated weatherreporter Markdown reports to a configured
+distributor HTTP upload endpoint. It isolates distributor package types,
+token-env lookup, upload client construction, source-bundle file mapping,
+timeout handling, and upload error wrapping from app orchestration.
+
+## Inputs And Outputs
+
+Inputs:
+
+- distributor endpoint URL
+- token environment variable name
+- upload timeout
+- bundle ID
+- idempotency key
+- source Markdown report path
+- bundle-relative Markdown path
+- context for cancellation
+
+Outputs:
+
+- accepted distributor run ID
+- accepted distributor status
+- weatherreporter-owned idempotency conflict error when applicable
+
+## Boundaries
+
+`internal/adapters/distributor` is the only weatherreporter package that imports
+`gitea.maximumdirect.net/eric/distributor/pkg/upload` or
+`gitea.maximumdirect.net/eric/distributor/pkg/bundle`.
+
+The app layer passes weatherreporter-owned request values to the adapter. The
+adapter does not choose report types, render templates, select output copies,
+configure destinations, wait for downstream publication, transform Markdown, or
+persist notification state.
+
+Full upstream distributor package and HTTP contract details stay under
+`docs/integrations/distributor/`.
+
+## Config Fields Used
+
+The adapter is built from `notify.distributor` config:
+
+- `endpoint`
+- `token_env`
+- `timeout`
+
+The app layer renders bundle ID, idempotency key, and bundle path from:
+
+- `bundle_id_template`
+- `idempotency_key_template`
+- `report_path_template`
+
+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 exactly one file:
+
+- source path: the managed Markdown report path selected by app orchestration
+- bundle path: the rendered bundle-relative report path
+
+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.
+
+## Failure Behavior
+
+The adapter validates required endpoint, token env name, token value, bundle ID,
+idempotency key, source path, bundle path, and upload client inputs before
+uploading.
+
+Upload failures include endpoint, bundle ID, idempotency key, source path, and
+bundle path 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.
+
+## Tests
+
+Inspect:
+
+- `internal/adapters/distributor/client_test.go`
+- `internal/app/app_test.go`
+- `internal/cli/root_test.go`
+
+Adapter tests use a fake upload client factory and do not require a live
+distributor service.
+
+## Invariants
+
+- Distributor package types do not leak outside the adapter.
+- Only the managed Markdown report is uploaded.
+- The adapter never scans the workspace.
+- Token values are not included in errors, CLI output, metadata, docs, or
+  examples.
+- Destination routing and Markdown-to-HTML transformation belong to
+  distributor, not weatherreporter.

+## Distributor Notification
+
+Distributor notification is configured with `notify.distributor` and is disabled

+operator conveniences only.
+
+The default bundle ID is derived from producer name, location ID, report ID, and
+RunID:
+
+```text
+weatherreporter.{location_id}.{report_id}.{run_id}
+```
+
+The default idempotency key is the rendered bundle ID. The default bundle path
+for the Markdown file is the report definition's batch output name, such as
+`daily.md`, `tomorrow.md`, `three-day.md`, or `weekend.md`.
+
+Notification happens after final metadata save. Weather API, briefing,

+not trigger notification. A notification failure fails that report. In a batch,
+other reports continue, the failed report includes notification fields in the
+JSON summary, and the batch returns nonzero.

+HTTP endpoint. Distributor remains responsible for destination routing,

-## Current Repository Facts
+## Deferred Enhancements
 
-- `weatherreporter` does not currently implement a notify hook.
-- Generated Markdown reports are written to the managed report path returned as
-  `ReportResult.ReportPath`.
-- Optional `--out` and `--out-dir` copies are user-requested extra copies and
-  are not canonical integration inputs.
-- The managed workspace also contains briefing snapshots, metadata, prompt data
-  packages, and preflight artifacts; these should not be treated as a
-  distributor source tree.
-- The provided distributor docs recommend `pkg/upload.UploadFiles` for
-  producers that already have generated files, so the initial integration can
-  upload selected report files directly.
+- Add a supported warning-only notification policy.
+- Include selected non-report artifacts in uploaded bundles.
+- Poll distributor run status after upload acceptance.
+- Persist upload retry state across process restarts.
+- Add explicit CLI controls for distributor behavior.
 
-## Decisions Locked
+## Non-Goals Without A Separate Design
 
-- Add generic configurable secrets-directory support before the distributor
-  adapter work. This is project infrastructure, not a distributor-only token
-  helper.
-- When a secrets directory is configured, each regular file directly under that
-  directory maps filename to environment variable name and file contents to
-  environment variable value.
-- Secret-file values overwrite pre-existing environment variables.
-- Secrets loading must never log, print, persist, or include secret values in
-  errors, metadata, batch output, examples, or docs.
-- Add a narrow `internal/adapters/distributor` adapter for the external
-  integration.
-- Keep `gitea.maximumdirect.net/eric/distributor/pkg/upload` and
-  `gitea.maximumdirect.net/eric/distributor/pkg/bundle` types inside that
-  adapter.
-- Upload one distributor bundle per successfully generated report.
-- Include only the generated Markdown report in the initial bundle.
-- Use the report definition's batch output filename as the default
-  bundle-relative Markdown path, such as `daily.md`, `tomorrow.md`,
-  `three-day.md`, `weekend.md`, or `storm.md`.
-- Derive the default bundle ID and idempotency key from producer name, location
-  ID, report ID, and RunID.
-- Treat distributor upload failure as a report failure when notification is
-  enabled; single-report and batch commands should exit nonzero for enabled
-  upload failures.
-- Keep destination routing, Markdown-to-HTML transformation, public URLs, and
-  nginx directory layout in distributor configuration, not in
-  `weatherreporter`.
+- Do not make distributor scan the weatherreporter workspace.
+- Do not move destination routing into weatherreporter.
+- Do not move Markdown-to-HTML transformation into weatherreporter.
+- Do not store raw bearer tokens in configuration files.
 
-## Planned Configuration
+## Required Constraints For Future Work
 
-Add future generic secrets configuration:
-
-```yaml
-secrets:
-  directory: ""
-```
-
-Add future distributor configuration under `notify.distributor`:
-
-```yaml
-notify:
-  distributor:
-    enabled: false
-    endpoint: https://distributor.example.com
-    token_env: DISTRIBUTOR_UPLOAD_TOKEN
-    timeout: 30s
-    failure_policy: error
-    bundle_id_template: "weatherreporter.{location_id}.{report_id}.{run_id}"
-    idempotency_key_template: "{bundle_id}"
-    report_path_template: "{batch_output_name}"
-```
-
-Planned behavior:
-
-- `secrets.directory` defaults to an empty string, which disables secrets
-  loading.
-- When `secrets.directory` is configured, load only regular files directly
-  under that directory.
-- Each secret filename must be a valid environment variable name matching
-  `[A-Za-z_][A-Za-z0-9_]*`.
-- Reject missing configured directory, invalid filenames, subdirectories,
-  symlinks, unreadable files, and empty filenames.
-- Strip one trailing `\n` or `\r\n` from secret file contents for compatibility
-  with common mounted-secret formats. Preserve all other bytes.
-- `enabled` defaults to `false`.
-- `endpoint` is required only when distributor notification is enabled.
-- `token_env` is required only when enabled. Raw bearer tokens should not be
-  stored in config files. The token value is read from normal environment state
-  after secrets-directory loading has been applied.
-- `timeout` controls the upload call timeout and should default to `30s`.
-- `failure_policy` should initially support `error`. Reserve `warn` as a
-  future option only if it is implemented and tested.
-- Template variables should be explicit and validated:
-  `location_id`, `report_id`, `run_id`, `artifact_group`, and
-  `batch_output_name`.
-- `idempotency_key_template` may reference `{bundle_id}` after the bundle ID is
-  rendered.
-- `report_path_template` should be user-visible from the first implementation
-  because bundle-relative paths can affect downstream distributor routing.
-- Rendered template values must produce valid distributor bundle paths: relative
-  slash-separated paths with no empty path, absolute path, backslash, `.`, `..`,
-  empty segment, `manifest.json`, or `.distributor.json`.
-
-## Recommended Implementation Stages
-
-### Stage 1: Secrets Directory Support
-
-Goal: add generic file-backed environment secret loading before distributor
-notification depends on environment tokens.
-
-Implementation guidance:
-
-- Add a generic `secrets.directory` config field under `internal/config`.
-- Default the directory to an empty string so secrets loading is disabled unless
-  explicitly configured.
-- Load secrets after config file parsing and before validation that needs
-  environment-backed values.
-- Map each regular file directly under the configured directory to an
-  environment variable: filename becomes the variable name and contents become
-  the value.
-- Use secret-file values to overwrite pre-existing environment variables.
-- Strip one trailing `\n` or `\r\n`; preserve all other bytes.
-- Reject missing directories, invalid environment-variable filenames,
-  subdirectories, symlinks, unreadable files, and empty filenames.
-- Keep secret values out of errors, logs, CLI output, metadata, and examples.
-
-Acceptance criteria:
-
-- Empty `secrets.directory` performs no environment changes.
-- Configured secrets directory values are available through normal environment
-  lookup after config loading.
-- Secret files overwrite existing environment variables with the same name.
-- Invalid directory entries fail with path/name context but without secret
-  values.
-- Existing config loading behavior remains unchanged when secrets are disabled.
-
-Suggested tests:
-
-- Config defaults leave secrets loading disabled.
-- A configured missing secrets directory fails.
-- Regular files set environment variables and overwrite existing values.
-- Invalid filenames, subdirectories, symlinks, and unreadable files fail.
-- One trailing newline or CRLF is stripped; other content is preserved.
-- No secret values appear in returned errors.
-
-### Stage 2: Config And Validation
-
-Goal: add disabled-by-default distributor notification configuration.
-
-Implementation guidance:
-
-- Add notify/distributor config structs under `internal/config`.
-- Add defaults for disabled notification, timeout, failure policy, bundle ID
-  template, idempotency key template, and report path template.
-- Validate enabled config: endpoint must be an absolute URL, `token_env` must be
-  non-empty, timeout must be positive, failure policy must be supported, and
-  templates must use only known variables.
-- Keep `token_env` as the configured token selector. Do not add raw token config.
-- Update maintained examples and config documentation only after code support is
-  implemented.
-
-Acceptance criteria:
-
-- Disabled distributor notification requires no endpoint or token env.
-- Enabled distributor notification rejects invalid endpoint, missing token env,
-  nonpositive timeout, unsupported failure policy, unknown template variables,
-  and invalid rendered report bundle paths.
-- Existing config loading behavior and precedence remain unchanged.
-
-Suggested tests:
-
-- Config defaults include disabled distributor notification.
-- Example configs load successfully.
-- Enabled config validation covers required fields and invalid template cases.
-- A distributor token supplied through `secrets.directory` is visible through
-  the configured `token_env` name after config loading.
-
-### Stage 3: Distributor Adapter
-
-Goal: isolate distributor package usage behind an internal adapter.
-
-Implementation guidance:
-
-- Add `internal/adapters/distributor` with package-owned request and result
-  types.
-- Read the bearer token from the configured environment variable after
-  secrets-directory loading has populated environment state.
-- Use distributor `UploadFiles` with one file:
-  the managed Markdown report as the source path and the rendered
-  `report_path_template` as the bundle path.
-- Return upload result information that app orchestration can record or expose
-  without leaking distributor dependency types.
-- Wrap upload errors with endpoint, bundle ID, and report path context while
-  avoiding token exposure.
-
-Acceptance criteria:
-
-- No distributor dependency types leak outside `internal/adapters/distributor`.
-- Missing source report path, missing token, invalid bundle path, and upload
-  failure return actionable errors.
-- Idempotency conflict errors are preserved or wrapped clearly enough for
-  troubleshooting.
-
-Suggested tests:
-
-- Adapter request construction uses the configured endpoint, token, bundle ID,
-  idempotency key, source report path, and bundle-relative path.
-- Token values do not appear in returned errors.
-- Upload conflict and generic upload failure produce useful wrapped errors.
-- Tokens supplied through the secrets directory are accepted via `token_env`.
-
-### Stage 4: App Notify Hook
-
-Goal: upload successful generated reports through the configured notifier.
-
-Implementation guidance:
-
-- Add an app-owned notifier interface so app tests can use fakes.
-- Construct distributor notification requests from the successful
-  `ReportResult`, resolved report definition, configured location, and
-  notification config.
-- Invoke notification only after Scriptorium report generation succeeds and
-  final metadata has been saved.
-- Do not notify after Weather API, briefing, prompt input, render preflight, or
-  Scriptorium run failure.
-- In batch mode, notify each successful report independently. If notification
-  fails and distributor notification is enabled, mark that report failed and
-  make the aggregate batch result nonzero.
-
-Acceptance criteria:
-
-- Disabled notification is a no-op.
-- Single-report generation returns an error when enabled upload fails.
-- Batch generation continues independent reports, records upload failures per
-  report, and exits nonzero when any enabled notification fails.
-- Existing report artifact paths, optional output copies, and Scriptorium
-  behavior remain unchanged.
-
-Suggested tests:
-
-- No notifier call occurs before successful report generation.
-- Successful notifier call receives the managed report path, not `--out` or
-  `--out-dir` copy paths.
-- Enabled notifier failure affects single-report and batch command outcomes.
-- Batch still continues later reports after one notification failure.
-
-### Stage 5: CLI And Output Behavior
-
-Goal: preserve CLI syntax while surfacing notification outcome where useful.
-
-Implementation guidance:
-
-- Do not add distributor-specific CLI flags in the first implementation; use
-  configuration only.
-- Preserve existing command names, flags, help text shape, workspace paths, and
-  generated Markdown outputs.
-- Extend batch JSON report items only if the implementation records useful
-  notification status, accepted distributor run ID, or notification error.
-- Keep stderr status lines concise and avoid exposing secrets.
-
-Acceptance criteria:
-
-- `go run ./cmd/weatherreporter --help` remains accurate.
-- Existing generate and run command syntax remains stable.
-- Batch summaries clearly indicate notification-caused report failures if
-  notification status is added.
-
-Suggested tests:
-
-- Existing CLI parser tests continue to pass.
-- Batch JSON includes notification fields only when implemented and documented.
-- Secret-like token values never appear in CLI output.
-
-### Stage 6: Documentation
-
-Goal: document implemented distributor behavior after the feature exists.
-
-Implementation guidance:
-
-- Update `docs/config.md` with `secrets.directory`,
-  `notify.distributor` fields, and defaults.
-- Update `docs/operations.md` with notification timing, failure behavior, and
-  the fact that managed report paths are uploaded.
-- Update `docs/troubleshooting.md` with invalid secrets directory, missing
-  token, upload conflict, upload rejection, and distributor unavailable cases.
-- Update `docs/internal/app-orchestration.md` to include notify ordering.
-- Add `docs/internal/distributor-adapter.md` for the adapter contract.
-- Keep distributor API details in `docs/integrations/distributor/`; link there
-  instead of duplicating the full upstream contract.
-
-Acceptance criteria:
-
-- Non-roadmap docs describe only implemented notification behavior.
-- Config examples include no raw tokens.
-- Secret handling documentation describes mechanisms, not secret values.
-- Documentation clearly distinguishes distributor destination routing from
-  weatherreporter upload responsibilities.
-
-### Stage 7: Final Validation
-
-Goal: verify the feature without requiring live distributor service access.
-
-Validation commands:
-
-```bash
-go test ./...
-go run ./cmd/weatherreporter --help
-git diff --check
-```
-
-Additional validation:
-
-- Run focused config, adapter, app, and CLI tests.
-- Confirm maintained example configs load.
-- Search for accidental raw-token config examples.
-- Confirm `go.mod` includes distributor only after implementation requires it.
-- Confirm no test failures leak secret values in error output.
-
-## Open Questions

+# Distributor Follow-Up Roadmap
 
-This roadmap turns `docs/roadmap/distributor.md` into staged implementation
-work for a future coding agent. It is a planning document only. The feature is
-not implemented until the stages below are completed and the implemented docs
-are updated.
+Current distributor notification behavior is documented in:
 
-## Purpose
+- [Configuration reference](../config.md)
+- [Operations guide](../operations.md)
+- [Troubleshooting](../troubleshooting.md)

-Implement generic file-backed environment secrets and distributor notification
-support while preserving current CLI syntax, managed artifact paths, RunIDs,
-and report output behavior. Distributor package types must stay behind a narrow
-adapter boundary, and distributor should receive explicitly selected generated
-Markdown files rather than scanning `workspace/`.
+This roadmap tracks only future work that is not implemented.
 
-## Locked Decisions
+## Deferred Enhancements
 
-- Implement generic `secrets.directory` support before distributor notification.
-- Secret files overwrite pre-existing environment variables.
-- Never expose secret values in errors, logs, CLI output, metadata, docs, or
-  examples.
-- Add `notify.distributor` config; do not add raw token config.
-- Keep public CLI commands and flags unchanged.
-- Upload one distributor bundle per successfully generated report.
-- Initial distributor bundles include only the managed Markdown report at
-  `ReportResult.ReportPath`.
-- The default bundle-relative Markdown path uses the report definition's
-  `BatchOutputName`.
-- Default bundle ID and idempotency key derive from producer, location ID,
-  report ID, and RunID.
-- Enabled distributor upload failure is a report failure and should produce a
-  nonzero command exit.
+- Support a non-failing distributor notification policy such as
+  `failure_policy: warn`.
+- Upload additional generated artifacts, such as metadata, briefing snapshots,
+  data packages, or preflight output.
+- Poll distributor status after upload acceptance and expose downstream
+  publication failures.
+- Add durable retry queues for upload failures.
+- Add distributor-specific CLI controls if operators need per-run behavior that
+  configuration cannot cover cleanly.
 
-## Stage 1: Secrets Directory Support
+## Boundaries To Preserve
 
-Goal: implement generic file-backed environment secret loading in
-`internal/config`.
-
-Implementation guidance:
-
-- Add `secrets.directory` config with a built-in default of `""`, meaning
-  disabled.
-- Load secrets after config file parsing and CLI overrides, before validation
-  completes.
-- Read only regular files directly under the configured directory.
-- Map each file basename to an environment variable name and file contents to
-  the value.
-- Validate names with `[A-Za-z_][A-Za-z0-9_]*`.
-- Reject missing configured directory, invalid filenames, subdirectories,
-  symlinks, unreadable files, and empty filenames.
-- Strip one trailing `\n` or `\r\n`; preserve all other bytes.
-- Keep error messages actionable but do not include secret values.
-
-Acceptance criteria:
-
-- Empty `secrets.directory` performs no environment changes.
-- Valid secret files set environment variables after config loading.
-- Secret file values overwrite existing environment variables.
-- Invalid entries fail before application workflows run.
-- Existing config loading behavior remains unchanged when secrets are disabled.
-
-Tests:
-
-- Defaults leave secrets loading disabled.
-- Valid file sets an environment variable.
-- File value overwrites an existing environment variable.
-- Missing directory, invalid filename, subdirectory, symlink, and unreadable
-  file cases fail.
-- Newline and CRLF trimming works exactly once.
-- Secret values are absent from error strings.
-
-## Stage 2: Notify Configuration And Templates
-
-Goal: add disabled-by-default `notify.distributor` config and template
-validation.
-
-Planned config:
-
-```yaml
-notify:
-  distributor:
-    enabled: false
-    endpoint: https://distributor.example.com
-    token_env: DISTRIBUTOR_UPLOAD_TOKEN
-    timeout: 30s
-    failure_policy: error
-    bundle_id_template: "weatherreporter.{location_id}.{report_id}.{run_id}"
-    idempotency_key_template: "{bundle_id}"
-    report_path_template: "{batch_output_name}"
-```
-
-Implementation guidance:
-
-- Add notify/distributor config structs, defaults, YAML loading, and validation
-  under `internal/config`.
-- When disabled, omit endpoint and token requirements.
-- When enabled, validate absolute endpoint URL, non-empty `token_env`, positive
-  timeout, `failure_policy=error`, known template variables, and valid rendered
-  report bundle paths.
-- Supported template variables are `location_id`, `report_id`, `run_id`,
-  `artifact_group`, and `batch_output_name`; `idempotency_key_template` may
-  also reference `{bundle_id}`.
-- Do not add distributor-specific CLI flags.
-
-Acceptance criteria:
-
-- Defaults include disabled distributor notification.
-- Enabled config rejects invalid endpoint, token env, timeout, failure policy,
-  templates, and rendered bundle paths.
-- Rendered bundle paths reject absolute paths, backslashes, `.`, `..`, empty
-  segments, `manifest.json`, and `.distributor.json`.
-- Tokens supplied by `secrets.directory` are visible through `token_env` after
-  config loading.
-
-Tests:
-
-- Config defaults and examples load.
-- Disabled distributor config accepts omitted distributor fields.
-- Enabled validation covers each invalid field.
-- Template rendering and validation are covered with table tests.
-
-## Stage 3: Distributor Adapter
-
-Goal: isolate distributor upload behavior in `internal/adapters/distributor`.
-
-Implementation guidance:
-
-- Add weatherreporter-owned request and result types.
-- Keep `gitea.maximumdirect.net/eric/distributor/pkg/upload` and
-  `gitea.maximumdirect.net/eric/distributor/pkg/bundle` types inside the
-  adapter.
-- Read the bearer token from `token_env` after config/secrets loading.
-- Use `UploadFiles` with exactly one file: source path is the managed Markdown
-  report path and bundle path is the rendered `report_path_template`.
-- Return the accepted distributor run ID when available.
-- Wrap endpoint, bundle ID, idempotency key, source path, and bundle path
-  context into errors without exposing token values.
-- Preserve idempotency conflict diagnosis.
-
-Acceptance criteria:
-
-- No distributor dependency types leak outside the adapter.
-- Missing token, source path, bundle path, or upload client inputs fail with
-  actionable errors.
-- Upload success returns a weatherreporter-owned result.
-- Upload failure errors do not include token values.
-
-Tests:
-
-- Fake upload client receives expected endpoint, token, bundle ID, idempotency
-  key, source path, and bundle path.
-- Missing token/source path/bundle path errors are actionable.
-- Token values are not present in errors.
-- Upload conflict and generic failure are wrapped clearly.
-
-## Stage 4: App Notification Hook
-
-Goal: add app-level notification orchestration after successful report
-generation.
-
-Implementation guidance:
-
-- Add an app-owned notifier interface for tests.
-- Default to no-op notification when distributor notification is disabled.
-- Notify only after successful `scriptorium run` and final metadata save.
-- Use `ReportResult.ReportPath` as the distributor source file.
-- Never use `--out` or `--out-dir` copies as distributor source files.
-- Do not notify after Weather API, briefing, prompt input, render preflight, or
-  Scriptorium run failure.
-- Single-report generation should return an error when enabled notification
-  fails.
-- Batch generation should continue independent reports; notification failure
-  marks that report failed and makes the aggregate batch nonzero.
-
-Acceptance criteria:
-
-- Disabled notification leaves current generation behavior unchanged.
-- Successful notification is recorded in the app result when useful.
-- Enabled notification failure fails a single-report command.
-- Batch results distinguish generation failure from notification failure enough
-  for operators to diagnose the failed report.
-- Existing artifact paths, output copies, and Scriptorium behavior remain
-  unchanged.
-
-Tests:
-
-- No notifier call occurs on pre-generation failures.
-- Notifier receives the managed report path.
-- Enabled notifier success and failure are covered.
-- Batch continues after one notification failure and reports aggregate failure.
-
-## Stage 5: CLI Output And Batch Reporting
-
-Goal: keep public CLI syntax stable while surfacing notification outcome if the
-app records it.
-
-Implementation guidance:
-
-- Do not add distributor-specific CLI flags.
-- Preserve current command names, help shape, generated paths, `--out`, and
-  `--out-dir`.
-- If batch JSON is extended, use explicit fields such as
-  `notificationStatus`, `notificationRunId`, and `notificationError`.
-- Keep stderr status lines concise and secret-free.
-
-Acceptance criteria:
-
-- `weatherreporter --help` remains accurate.
-- Existing CLI parser behavior remains stable.
-- Batch JSON includes notification details only when implemented and
-  documented.
-- CLI stdout and stderr do not include token values.
-
-Tests:
-
-- Existing CLI parser tests pass, except intentional JSON additions.
-- Batch output covers notification success and failure.
-- Secret-like token values are absent from CLI output.
-
-## Stage 6: Documentation
-
-Goal: update implemented documentation after the feature exists.
-
-Implementation guidance:
-
-- Update `docs/config.md` with `secrets.directory`, `notify.distributor`,
-  defaults, and secret handling.
-- Update `docs/operations.md` with notification timing, failure behavior, and
-  managed report upload source.
-- Update `docs/troubleshooting.md` with invalid secrets directory, missing
-  token, upload conflict, upload rejection, and distributor unavailable cases.
-- Update `docs/internal/app-orchestration.md` to include notify ordering.
-- Add `docs/internal/distributor-adapter.md` for adapter inputs, outputs,
-  boundaries, config fields, failure behavior, tests, and invariants.
-- Keep full upstream distributor contract details in
-  `docs/integrations/distributor/`.
-
-Acceptance criteria:
-
-- Non-roadmap docs describe only implemented behavior.
-- Config examples load and contain no raw secrets.
-- Secret handling docs describe mechanisms, not secret values.
-- Docs distinguish weatherreporter upload responsibility from distributor
-  destination routing and Markdown-to-HTML transformation.
-
-Tests and checks:
-
-- Run config example loading tests.
-- Search docs and examples for accidental raw tokens.
-- Run `git diff --check`.
-
-## Stage 7: Final Validation
-
-Goal: verify behavior without a live distributor service.
-
-Validation commands:
-
-```bash
-go test ./...
-go run ./cmd/weatherreporter --help
-git diff --check
-go test ./internal/config ./internal/app ./internal/cli ./internal/adapters/distributor
-```
-
-Manual validation:
-
-- No token values appear in errors, CLI output, docs, examples, metadata, or
-  batch JSON.
-- `go.mod` includes distributor only after adapter implementation requires it.
-- Existing report paths, RunIDs, and `--out` / `--out-dir` behavior are
-  unchanged.
-- Distributor upload tests use fakes or local test doubles, not a live service.
-
-## Deferred Work
-
-These are out of scope for the initial implementation:
-
-- `failure_policy: warn`.
-- Uploading metadata, briefing, data package, or preflight artifacts.
-- Distributor status polling after `202 Accepted`.
-- Durable upload retry queues.
-- Distributor-specific CLI flags.
-- Making distributor scan `workspace/`.
-- Destination routing, Markdown-to-HTML transformation, public URLs, or nginx
-  layout in `weatherreporter`.
-
-## Global Validation Checklist
-
-- Preserve current public CLI syntax.
-- Preserve managed workspace artifact paths.
+- Keep public CLI syntax stable unless a separate CLI design changes it.
+- Keep managed workspace artifact paths and RunIDs stable.
 - Keep distributor dependency types behind `internal/adapters/distributor`.
-- Keep secrets out of user-facing and persisted output.
-- Keep examples valid and secret-free.
-- Update implemented docs in the same change as implementation.
-- Run `go test ./...`, `go run ./cmd/weatherreporter --help`, and
-  `git diff --check` before finishing implementation.
-
+- Keep raw token values out of errors, CLI output, metadata, docs, examples,
+  and persisted artifacts.
+- Upload explicitly selected generated files; do not make distributor scan the
+  weatherreporter workspace.
+- Leave destination routing, Markdown-to-HTML transformation, public URLs, and
+  nginx layout to distributor.

+## 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.
+By default the key derives from bundle ID, which includes location ID, report
+ID, and RunID.
+
+Diagnostic: inspect the failed batch JSON or stderr line for bundle and
+idempotency context. Compare the configured templates with the report RunID and
+report path.
+
+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, bundle ID,
+idempotency key, source file, or bundle path.
+
+Diagnostic: inspect stdout JSON or stderr status lines for
+`notificationError`. Confirm `notify.distributor.endpoint`,
+`notify.distributor.report_path_template`, and token configuration. Token values
+are redacted from weatherreporter errors.
+
+Safe fix: fix the endpoint, token, templates, or distributor-side upload
+configuration. The weatherreporter upload source is the managed Markdown report,
+not `--out` or `--out-dir` copies.
+
+Relevant docs: [Configuration reference](config.md),
+[Operations guide](operations.md),
+[Distributor adapter internals](internal/distributor-adapter.md).
+
+## Distributor Unavailable
+
+Symptom: notification fails with network, timeout, or service unavailable
+context.
+
+Likely cause: the configured distributor endpoint is unreachable, slow, or
+temporarily unavailable.
+
+Diagnostic: check network access from the weatherreporter host to
+`notify.distributor.endpoint`. For batch runs, inspect which reports have
+`notificationStatus: "failed"`.
+
+Safe fix: restore distributor service availability and rerun the affected
+report or batch. Stable idempotency keys make retrying the same generated report
+safe unless the distributor reports a conflict.
