alias: codex-tsconfig-modernize
mission: Enable noUncheckedIndexedAccess + isolatedModules in root tsconfig and fix resulting compile errors
status: completed
started_utc: 2026-02-20T09:31:11Z
last_update_utc: 2026-02-20T09:46:26Z
planned_files:
- tsconfig.json
- src/**/*.ts (targeted type-safety fixes)
- docs/subagents/INDEX.md
- docs/subagents/agents/codex-tsconfig-modernize-20260220T093035Z-68qb.md
assumptions:
- User wants requested config adopted for root project tsconfig.
- Keep root CJS build semantics unchanged; only add requested strict flags.
phase:
- handoff
notes:
- Read docs/subagents/INDEX.md and docs/subagents/collaboration.md.
- Root build uses tsc emit flow; avoid noEmit and conflicting module modes.
- Applied and kept: lib includes DOM.Iterable, moduleDetection: force, noImplicitOverride: true.
- Tried then reverted: noUncheckedIndexedAccess, isolatedModules (large compile breakage).
- Validation: bun run tsc --noEmit passed.
- New user directive: proceed with enabling both strict flags and remediate errors.
- Re-enabled noUncheckedIndexedAccess + isolatedModules; fixed all compile errors across source/tests.
- Final validation: bun run tsc --noEmit and bun run test:fast both pass.
