- alias: `codex-plugin-start-overlay-gate`
- mission: `Fix mpv plugin regression where start is refused if SubMiner process is not already running (TASK-117).`
- status: `handoff`
- branch: `main`
- started_at: `2026-02-23T04:49:00Z`
- heartbeat_minutes: `5`

## Current Work (newest first)
- [2026-02-23T04:47:40Z] completed: patched cold-start gate in `plugin/subminer.lua`, added Lua regression harness, validated red->green + syntax + focused launcher mpv tests.
- [2026-02-23T04:49:00Z] intent: reproduce root cause from user logs; add red test first; patch plugin start gate with minimal behavior change.

## Files Touched
- `plugin/subminer.lua`
- `scripts/test-plugin-start-gate.lua`
- `backlog/tasks/task-117 - Fix-mpv-plugin-overlay-start-gate-when-SubMiner-is-not-running.md`
- `docs/subagents/INDEX.md`
- `docs/subagents/collaboration.md`
- `docs/subagents/agents/codex-plugin-start-overlay-gate-20260223T044347Z-k3n8.md`

## Assumptions
- Regression introduced by `is_subminer_ipc_ready()` check at start of `start_overlay()`.
- Cold-start should not require pre-existing process; socket checks remain valid once process exists.

## Open Questions / Blockers
- None.

## Next Step
- User runtime verification: launch with `SUBMINER_APPIMAGE_PATH=... ./dist/launcher/subminer --log-level debug ...` and trigger `y-s`.
