## Current Work (newest first)

- [2026-02-21T23:26:29Z] handoff: Completed TASK-72 end-to-end (no commit): strict startup constructor loading, shared parse-error formatter wiring, startup fail-fast guard in `main.ts`, docs update, focused tests pass, backlog task finalized to Done.
- [2026-02-21T23:26:29Z] test: `bun test src/config/config.test.ts src/main/config-validation.test.ts src/main/runtime/startup-config.test.ts` passed (46/46); full `bun run build` blocked by unrelated pre-existing TASK-75/TASK-77 TypeScript errors outside TASK-72 scope.
- [2026-02-21T23:24:20Z] progress: executed plan Tasks 1-2 via parallel subagents (`opencode-task72-strict-startup-config-*`, `opencode-task72-parse-details-*`), then integrated Task 3 (`src/main.ts`) and Task 4 (`docs/configuration.md`) in-session.
- [2026-02-21T23:19:40Z] progress: wrote execution plan at `docs/plans/2026-02-21-task-72-strict-startup-config-loading.md` via writing-plans skill.
- [2026-02-21T23:18:04Z] intent: Load TASK-72 context from Backlog MCP, produce execution plan with writing-plans skill, then implement/test/docs updates without commit.
