+## M17 — grounded knowledge and integration evidence UX (2026-08-10)
+
+- Replaced transient false demo/unavailable/not-configured labels with explicit loading,
+  settled-unavailable and provider-aware states on Knowledge and Automation.
+- Deduplicated RAGcore citations by their human-visible identity instead of volatile
+  document/version UUIDs and capped each answer at three concise, collapsible source
+  cards. Re-uploaded copies can no longer dominate an answer.
+- Added answer latency and authenticated helpful/not-helpful feedback. Feedback is
+  correlation-bound to the requesting user, auditable and safely updateable without
+  creating duplicate audit events.
+- Explained the expected cadence of all four central n8n workflows so event-driven and
+  scheduled no-event states are understandable rather than looking broken.
+- Regenerated the OpenAPI contract. Evidence: frontend production build passed; focused
+  backend knowledge suite **31 passed**; targeted ruff and mypy checks passed. The E2E
+  journey now verifies the three-source limit, unique source titles and persisted
+  feedback.
+- Exact next action: turn the data-quality queue, booking planning, fleet overview and
+  user administration into complete daily operational workspaces.
