- eslint.config.js block 3: no-restricted-syntax bans Date.now() and
setInterval() inside src/sim/**, with src/sim/scheduler/clock.ts as
the single allowed wall-clock owner (CONTEXT D-33, RESEARCH Pitfall 1)
- date-now-violator.ts deliberate-violation fixture (excluded from
default lint by Block 1's top-level ignores; the programmatic ESLint
test passes ignore: false to override)
- lint-firewall.test.ts gains 2 new cases: positive (rule fires on
violator) + negative (rule does NOT fire on clock.ts the one exception)
- Existing CORE-10 firewall test left untouched and remains green
- src/sim/__test_violation__/violator.ts deliberately imports from
src/render/__firewall_target__.ts to trigger the firewall rule.
- src/sim/__test_violation__/lint-firewall.test.ts runs ESLint
programmatically (with ignore: false) against the violator and
asserts boundaries/element-types fires with severity=error and the
message mentions both 'sim' and 'render'.
- src/render/__firewall_target__.ts is a minimal export so the
boundaries plugin can resolve the import to a real path on disk.
Without a real target, the plugin marks the import as isUnknown
and silently skips the rule (verified empirically; see SUMMARY).
- eslint.config.js gains an import/resolver: typescript block so the
TS-aware resolver follows extension-less imports
('../../render/foo' -> src/render/foo.ts). Required by the
boundaries plugin's element classification of import targets.
- tsconfig.app.json excludes *.test.ts and src/sim/__test_violation__/
so 'tsc -b' does not try to typecheck Node-API-using test code with
the DOM-only project's lib settings; vitest still discovers them
via its own include glob.
- Added eslint-import-resolver-typescript as devDep.
Verifies green:
npm run lint -> 0 errors, 0 warnings (violator excluded)
npm test -> 2/2 pass (sentinel + firewall)
npm run build -> tsc -b clean, vite build clean
npx eslint --no-ignore src/sim/__test_violation__/violator.ts
-> exits 1 with the expected
boundaries/element-types error

- New eslint.config.js (flat, ESLint 9) declaring 9 element types:
the seven Phase-1 firewall directories (sim, render, ui, save,
content, audio, store) plus the template's app + game.
- One rule, severity error: sim cannot import from render or ui (CORE-10).
- Default posture allow — Phase 1 enforces ONE rule, not closed-by-default.
- src/sim/__test_violation__/ excluded from default lint glob; the rule's
end-to-end correctness is proven by Task 2's Vitest test, not by 'lint
exits 0 on clean code'.
- Added typescript-eslint as devDep (parser only — no rule sets) so
ESLint can parse .ts/.tsx (Espree default cannot). Documented as a
Plan 02 deviation in 01-02-SUMMARY.md (Rule 3 — Blocking).
Verifies green on the clean codebase: 0 errors, 0 warnings via
'npm run lint'. Stderr notices from boundaries plugin about deprecated
rule name (element-types vs dependencies in v6) and legacy selector
syntax are informational only — they don't count as ESLint warnings.
