Reviewer round 1 on the #260 collab-doc-name fix: - F1: replaceImage is the one path where the resolved UUID gates BOTH the collab-doc open AND the per-page mutex key (withPageLock(pageUuid)). Add a deterministic test to resolve-page-id-collab-doc-name.test.mjs: it gates /files/upload so replaceImage parks mid-upload holding its lock, asserts the doc opened as page.<uuid> (never page.<slug>), and probes the SHARED page-lock chain — a withPageLock(UUID) probe must stay blocked while replaceImage holds it (with a free-key probe as a non-vacuity guard). The test fails if the lock key is reverted to the slugId (verified). - F2: drop the dead `pageIdCache.set(uuid, uuid)` — resolvePageId returns on the isUuid() short-circuit before the cache is ever read with a uuid key, so only slugId->uuid entries are stored/read.
