+## M31 — verified RAG inventory and dashboard attention polish (2026-08-10)
+
+- RAGcore health now verifies every language-specific managed source through the
+  documented exact `/v1/documents` identity lookup. Only an active document with a
+  published active version and the authoritative Fleet Ops content hash is counted.
+  Lookups are bounded, concurrent and cached for five minutes; an unavailable verifier
+  remains explicitly unknown instead of being presented as zero or as a reported count.
+- Persisted n8n sync provenance no longer downgrades the stronger provider-verified
+  statistics state. The Knowledge Hub shows the verified count as a separate evidence
+  fact alongside source, sync and recency evidence, in all three supported languages.
+- The dashboard's remaining-attention action is now a compact 52 px evidence-backed row
+  with count badge, legible title/hint and a 14 px directional icon. The attention panel
+  no longer stretches to the neighbouring full-day timeline; desktop and responsive
+  layouts remain overflow-free.
+- Validation: isolated backend **241 passed**; Ruff clean; mypy clean across 58 files in
+  the locked container; frontend lint/build passed; focused visual regressions **5 passed**;
+  localized knowledge regressions **3 passed**; complete Playwright **152 passed in 5.4
+  minutes**; full and production npm audits report zero vulnerabilities. In-app visual
+  inspection confirmed the new action dimensions and presentation.
+- Exact next action: commit and push M31, create and verify a live database backup,
+  redeploy the committed archive, then verify live RAG inventory, create a real post-reset
+  MCP Hub tool-call audit record, and complete production browser/acceptance evidence.
