Result: FAIL

Token usage: input 173398, output 3127, total 176525

bun test ran but failed with 3 failing tests; the PR-introduced tests/file-size.test.ts currently fails because many existing .ts files exceed 250 lines, and two notification config tests also fail in the current checkout. I also could not refresh origin/main because git fetch origin main was blocked by the sandbox with cannot open '.git/FETCH_HEAD': Operation not permitted.

Bugs were detected and sent back to implementation.

Reviewed PR #64 changes locally against main; the production change is a behavior-preserving extraction of agent chat-log state helpers with re-exports maintained, and I found no PR bugs. bun test ran successfully with 253 passing tests; bun run typecheck also passed. Note: fetching latest origin/main was blocked by the sandbox writing .git/FETCH_HEAD, and bun run check fails on ignored local-only adhd-ai.local.config.ts, which is not in the PR diff.

No bugs found.
