23# Strict TypeScript: Zero-Error Batch
24 
25## Task
26 
27Add 16 files that already have zero strict-mode errors to `CORE_FILES` in `scripts/check-strict-core.js`. These files already pass `tsc --strict` with `noUncheckedIndexedAccess` — they just need to be registered.
28 
29## Branch
30 
31```
32git checkout main && git pull origin main && git checkout -b cursor/strict/zero-errors-batch
33```
34 
35## Files to Add to CORE_FILES
36 
37Add these entries to the `CORE_FILES` Set in `scripts/check-strict-core.js`, maintaining alphabetical order within each directory group:
38 
39```
40injected/src/features/click-to-load/ctl-config.js
41injected/src/features/context-menu.js
42injected/src/features/duckplayer-native/error-detection.js
43injected/src/features/duckplayer-native/sub-feature.js
44injected/src/features/page-observer.js
45injected/src/features/web-detection/matching.js
46injected/src/features/web-detection/parse.js
47injected/src/features/web-interference-detection.js
48injected/src/navigator-global.js
49injected/src/types/context-menu.ts
50injected/src/types/favicon.ts
51injected/src/types/hover.ts
52injected/src/types/page-observer.ts
53injected/src/types/print.ts
54injected/src/types/web-compat.ts
55injected/src/utils/dom-metadata.js
56```
57 
58## Expected Errors
59 
60**None.** All 16 files already compile clean under strict mode.
61 
62## Workflow
63 
641. `npm ci`
652. Add files to CORE_FILES in `scripts/check-strict-core.js`
663. `npm run tsc-strict-core` — must print "✅ All injected core files pass strict TypeScript checking."
674. `npm run test-unit` — must pass
685. `npm run lint` — must pass (run `npm run lint-fix` first if needed)
696. Commit: `fix(types): add 16 zero-error files to strict core checking`
707. `git push -u origin cursor/strict/zero-errors-batch`
71 
72## Constraints
73 
74- Do NOT modify any source files — only `scripts/check-strict-core.js`
75- Do NOT remove existing CORE_FILES entries
76- Do NOT add files that are not in the list above
