 - **Shipped on `claude/search-cross-mode-links-qscj1n`:** post-answer "Also in your library" strip (`src/lib/cross-mode-links.ts` + `CrossModeLinksStrip`), thread-wide entity fallback, word-boundary field matching in `rankCatalogRecords` (substring hits like "renal" inside "adrenaline" no longer count as name/title matches), `fields=index` slim mode on `/api/medications`, cross-mode click telemetry via `/api/search/interaction` (`crossMode` target, `metadata.interaction: "cross_mode_link_open"`), the same strip on documents-mode results, and answer `crossModes` command-surface parity.
 - **Verification debt:** `npm run verify:release` (and its governance/eval gates) has not been run for this workstream — the authoring environment has no live Supabase/OpenAI keys. Run it from a secrets-equipped environment after merge; the cross-mode surface itself is additive/navigational, so `verify:cheap` + `verify:ui` are the load-bearing local gates.
 - **Telemetry note:** cross-mode clicks write `rag_query_misses` rows with `clicked_document_id: null` and the target mode/slug in `metadata`; retrieval-quality reviews that aggregate misses by document should filter on `metadata.interaction`.

+## Answer-thread Back button: URL and visible answer can disagree (2026-07-06)
+
+- **Behaviour:** inside an Answer thread, browser Back changes the URL (`/?mode=answer&q=A&run=1` ← `...q=B&run=1`) but the rendered answer/thread does not change. Two guards produce this: the auto-run effect skips when `run=1` is already present, and the answer view early-returns when an answer is already on screen (`ClinicalDashboard`). This is thread persistence by design, not an accident — clearing the thread on Back would destroy in-progress clinical context.
+- **Open product decision:** either (a) accept that the URL is not a faithful pointer to the visible answer inside a thread (current state), or (b) make Back restore the previous question's answer from thread history. Option (b) needs answer-thread state keyed by URL and re-render on `popstate`/param change; it is a deliberate feature, not a bug fix.
+- **Guardrail until decided:** do not "fix" the skipped auto-run on Back in isolation — re-running the search on Back would clobber the visible thread with a regenerated (and possibly different) answer, which is worse than either deliberate option.
