+## M25 — provenance-aware knowledge statistics (2026-08-10)
+
+- Expanded knowledge health with separate counts for authoritative local source
+  documents, the latest persisted n8n sync report and documents independently verified
+  as indexed. The API includes failed sync count, report time and an explicit statistics
+  provenance state.
+- Confirmed against RAGcore's checked-in OpenAPI and route implementation that the
+  service intentionally exposes identity-based single-document lookup but no corpus-size
+  or space-browse endpoint. Fleet Ops therefore keeps `document_count=null` for RAGcore
+  and never mislabels an accepted upload as proven indexing/publication.
+- Knowledge, dashboard and Integration Management now present the available source and
+  sync evidence in all three locales. The deterministic demo provider continues to
+  report its directly verified per-language corpus count.
+- Regenerated the Fleet Ops OpenAPI contract and documented the provenance rules.
+- Evidence: focused knowledge/demo suite **36 passed with zero warnings** from a rebuilt
+  image; ruff/mypy passed; frontend TypeScript lint and production build passed. The
+  prior Starlette/httpx warning is confirmed absent in the rebuilt environment.
+- Exact next action: run complete clean acceptance, push all five milestone commits,
+  create a verified live backup, redeploy and execute live browser acceptance.

+The versioned Markdown files under `knowledge/procedures/` (currently eleven per supported
+language) are the authoritative sources. Keep their IDs, versions and effective dates as
+metadata.
+
+## Index statistics and provenance
+
+`GET /api/v1/knowledge/status` keeps three different measurements separate:
+
+- `source_document_count`: authoritative procedure files available to Fleet Ops for the requested language;
+- `reported_synced_document_count`, `reported_failed_document_count` and `last_sync_at`: the latest persisted result reported by the central n8n synchronization workflow;
+- `document_count`: documents independently verified as indexed by the active provider.
+
+The current RAGcore contract deliberately has no corpus-size or space-browse endpoint. For
+the RAGcore provider, `document_count` therefore remains `null`; a successful upload report
+is never relabelled as proof that indexing and publishing completed. The deterministic demo
+provider can verify its in-memory corpus and reports `statistics_state=verified`. RAGcore
+reports `sync_reported` only when a persisted workflow callback exists, otherwise
+`not_reported`.
