main f17c9d202b: vp i; vp run dev (PID 15474, server 16733, web 8693).
Created local git repo cursor-store-verification through Add project > New project.

PR f4d3659e2ddea871eb47591c34d7b9499b9e3712: vp i; vp run dev --home-dir /home/user/t3code/.t3 (server 13773, web 5733).
Created separate local git repo with the same name and sent matching prompts through web UI.
Codex gpt-6.1-sol: ACK; cedar-24859. Reload: both replies present.
Stopped captured server process group and restarted against the same isolated data.
Third UI turn asked for the earlier word without repeating it: cedar-24859.
Same native provider thread persisted across restart. No repeated replies in the exercised Codex turns.

Cursor added through Settings > Providers > Add provider on main and PR.
PR UI: Not authenticated; Sign in with Cursor or add CURSOR_API_KEY in provider settings; 0 models.
cursor-agent status: Not logged in.
Original Windows MAX_PATH/SQLite failure could not be reproduced on Linux.
No authenticated Cursor turn, Windows write, or Windows resume was exercised.
Codex results are neighboring integration checks, not proof of the Cursor fix.

Blacksmith checks on exact PR head:
vp test run packages/provider-cursor/src/server/CursorAgentSdk.test.ts -> 3 passed
vp test run apps/server/src/orchestration-v2/testkit/CursorReplayFixtures.integration.test.ts -> 11 passed
Replay fixtures use recorded SDK behavior; they are not real Cursor provider turns.
No source changes, commits, pushes, labels, merge, close, rebase, or force-push.
