# Agent Log: codex-task74-launcher-tests-20260221T201635Z-10i6

- alias: `codex-task74-launcher-tests`
- mission: `Implement TASK-74 launcher regression tests for config discovery + command branching end-to-end`
- status: `done`
- last_update_utc: `2026-02-21T20:20:52Z`

## Intent

- add launcher regression coverage for config discovery matrix + command branching paths
- keep tests deterministic via fs/process/spawn mocks; no external process deps
- wire tests into existing launcher/core test workflow

## Planned Files

- `launcher/main.ts`
- `launcher/main.test.ts` (new)
- `launcher/config.test.ts` (extend if needed)
- `package.json` (only if test command wiring needed)
- `backlog/tasks/task-74 - Add-launcher-regression-tests-for-config-discovery-and-command-branching.md` (status/checklists evidence)

## Assumptions

- existing test runner: `bun test`
- task expects launcher tests in repo test gates (likely `test:launcher`)
- no behavior change needed unless tests expose branch gaps

## Progress

- `2026-02-21T20:16:35Z` started; protocol + task context loaded
- `2026-02-21T20:19:30Z` added `launcher/main.test.ts` regression suite (config discovery + command branching via child-process harness + fake app binary capture)
- `2026-02-21T20:20:02Z` wired launcher tests into scripts (`test:launcher:src`, `test:launcher`) and included launcher tests in `test:core:src`
- `2026-02-21T20:20:20Z` documented launcher test command in `docs/launcher-script.md`
- `2026-02-21T20:20:52Z` verification complete:
  - `bun run test:launcher`
  - `bun run test:core:src`
  - both green

## Files Touched

- `launcher/main.test.ts` (new)
- `package.json`
- `docs/launcher-script.md`
- `backlog/tasks/task-74 - Add-launcher-regression-tests-for-config-discovery-and-command-branching.md`
- `docs/subagents/INDEX.md`
- `docs/subagents/agents/codex-task74-launcher-tests-20260221T201635Z-10i6.md`

## Handoff

- task status moved to `Done` in backlog markdown with AC/DoD checked
- no blockers
