# Agent Session: opencode-task-94-20260221T033647Z-7ou2

- alias: `opencode-task-94`
- mission: `Finish TASK-94 thin composition root refactor and close acceptance criteria`
- status: `done`
- last_update_utc: `2026-02-21T04:12:45Z`

## Intent

- Pull TASK-94 context from Backlog MCP; verify remaining gap.
- Use writing-plans skill to produce execution plan.
- Use executing-plans skill to implement remaining extraction and verify gates.

## Planned Files

- `src/main.ts`
- `src/main/runtime/composers/*`
- `src/main/runtime/registry/*`
- `src/main/runtime/shared/*`
- `src/main/runtime/**/*.test.ts`
- `backlog/tasks/task-94 - Reduce-main.ts-to-thin-composition-root.md` (via MCP task edits only)

## Assumptions

- TASK-94 already has partial progress from prior slice.
- Remaining work targets acceptance criterion #1 only.
- No commit requested in this run.

## Activity Log

- `2026-02-21T03:36:58Z` session start; backlog/task context loaded; preparing planning skill.
- `2026-02-21T03:47:00Z` extracted IPC + shortcuts composition into dedicated composers; rewired `src/main.ts`; added composer tests.
- `2026-02-21T04:05:00Z` extracted startup-lifecycle + app-ready composition clusters into composer modules; rewired `src/main.ts` lifecycle/app-ready assembly.
