+
+- alias: `opencode-task98-source-tests`
+- mission: `Execute TASK-98 shift core tests to source level and trim dist coupling without commit`
+- status: `blocked`
+- started_utc: `2026-02-21T09:45:24Z`
+- backlog_task: `TASK-98`
+
+## Intent
+
+- Load TASK-98 context from Backlog MCP.
+- Build execution plan via `writing-plans` skill.
+- Execute with `executing-plans` skill.
+- Use parallel subagents where slices are independent.
+
+## Planned Files
+
+- `src/**/*.test.ts`
+- `scripts/**/*.mjs`
+- `package.json`
+- `docs/**/*.md`
+
+## Files Touched
+
+- `package.json`
+- `.github/workflows/ci.yml`
+- `.github/workflows/release.yml`
+- `docs/development.md`
+- `docs/plans/2026-02-21-task-98-source-tests-dist-smoke-split.md`
+- `docs/subagents/INDEX.md`
+- `docs/subagents/collaboration.md`
+
+## Assumptions
+
+- Backlog task exists and is actionable.
+- No commit requested.
+- Existing TASK-96/TASK-97 in-flight workspace changes may affect `bun run build` verification.
+
+## Next Step
+
+- Unblock `bun run build` from unrelated in-flight composer/type errors, then rerun CI-equivalent gate and close TASK-98 DoD #2.
+
+## Heartbeat Log
+
+- `2026-02-21T09:45:24Z` session start; subagent + backlog context loading.
+- `2026-02-21T09:51:00Z` plan written to `docs/plans/2026-02-21-task-98-source-tests-dist-smoke-split.md` and recorded in Backlog.
+- `2026-02-21T09:55:00Z` migrated default scripts to source lane; added explicit `test:smoke:dist`; rewired CI/release quality gate.
+- `2026-02-21T09:56:47Z` verification: source lane PASS; dist smoke PASS; `bun run build` blocked by unrelated pre-existing TS errors in `src/main.ts` and `src/main/runtime/composers/mpv-runtime-composer.test.ts`.
