 ## Log
 
 - `2026-02-22T00:25:23Z` session started; reading backlog + subagent context; entering planning.
+- `2026-02-22T00:53:25Z` implemented TASK-82 smoke suite + workflow/docs wiring; verified smoke/launcher/fast/docs lanes; finalized backlog TASK-82 Done (build/dist smoke blocked by unrelated TASK-80 IPC typing errors).

+- `package.json`
+- `.github/workflows/ci.yml`
+- `.github/workflows/release.yml`
+- `docs/development.md`
