# Agent Session: opencode-task100-dead-code-prune-20260222T033155Z-qenz

- alias: `opencode-task100-dead-code-prune`
- mission: `Execute TASK-100 dead-code prune and cleanup via writing-plans + executing-plans (no commit).`
- status: `done`
- started_utc: `2026-02-22T03:32:21Z`
- last_update_utc: `2026-02-22T04:00:41Z`

## Intent

- Load TASK-100 from Backlog MCP and capture a concrete execution plan.
- Run dead-code candidate discovery with import/export checks and safe pruning.
- Preserve behavior with regression-safe removals and gate verification.

## Planned Files

- `src/**/*.ts`
- `scripts/**/*.ts`
- `package.json`
- `docs/**/*.md`
- `docs/plans/*.md`

## Files Touched

- `docs/subagents/agents/opencode-task100-dead-code-prune-20260222T033155Z-qenz.md`
- `docs/subagents/INDEX.md`
- `docs/subagents/collaboration.md`
- `docs/plans/2026-02-22-task-100-dead-code-prune-cleanup.md`
- `docs/reports/2026-02-22-task-100-dead-code-report.md`

- `src/renderer/positioning/position-state.ts`
- `src/tokenizers/index.ts`
- `src/token-mergers/index.ts`
- `src/core/utils/index.ts`

## Assumptions

- TASK-100 scope is code/test/docs cleanup only; no feature behavior changes.
- Existing guardrails (`check:file-budgets`, runtime-cycle check, tests) are available.
- Parallel subagents can split dead-code scan and docs/report updates safely.

## Phase Log

- `2026-02-22T03:32:21Z` Session started; loaded backlog overview/TASK-100 and subagent coordination files.
- `2026-02-22T03:39:55Z` Wrote execution plan in `docs/plans/2026-02-22-task-100-dead-code-prune-cleanup.md` and started implementation.
- `2026-02-22T03:49:20Z` Parallel subagents completed dead-code candidate analysis and safe-removal shortlist.
- `2026-02-22T04:00:41Z` Completed dead-code removals + report, verified required gates, and finalized TASK-100 as Done in Backlog MCP.

## Next Step

- Finalize TASK-100 in Backlog MCP with report path and verification evidence.
