Source: /home/ubuntu/wt/issue-24160/.t3/userdata/statev2.sqlite
Access: sqlite URI mode=ro; PRAGMA query_only=ON; SELECT only.
Revision attribution supplied by lead: before=66ee628e0875b2b735b199f42e6151e347833637; after=e92888749daf8b70d2dd9603823e3f9d6c1b4644. Database rows do not independently encode server git revision.
Environment: isolated worktree .t3; machine fs-35. Provider claudeAgent / claude-opus-5-5. No server/browser started for extraction.
Chronology: before parent FIRST/SECOND/THIRD completed; old fork first /compact failed, normal FORK completed, subsequent /compact completed. After fresh fork first own /compact completed; nonfork empty control rejected in both revisions.
Scope: test fixture rows only; no credentials or general conversation dump. Compaction summary content omitted.

READ-ONLY CROSS-CHECKS: PASS (parent 3 completed; fresh fork from parent run3; exactly one local message /compact tied to completed run1; native provider fork; same-run completed compaction 84252 -> 1478; both empty controls rejected; old fork failed/completed/completed).
Fresh fork run requested 16:32:19.847Z; started 16:32:20.100Z; compaction 16:32:22.305Z–16:32:34.415Z; run completed 16:32:34.506Z (14.659 seconds from request).
Render paths: full base-to-head diff changes only ProjectionStore.ts and TurnStartReads.test.ts. Existing ProviderTurnStartService.ts:391 consumes hasConversation. No client renderer, contract, or persisted shape change. Empty capture matrix applies; no unverified affected rows claimed.
FRICTION: Revision attribution for historical runtime is lead-supplied, not stored in projection rows. Green count is 41 rather than earlier reported 36. Raw red reproduced without checkout mutation using temporary Vite pre-load substitution; two expected failures, other two passed. No server/browser/DB mutation/commit/forge write.
