eslint

1. Found behind latest

   Oct 28, 02:08 UTC

   eslint 8.57.1 is declared in package.json; the registry's latest is 9.37.0.

2. Compared the release's API

   ESLint 9 reads only eslint.config.* by default; the repository's .eslintrc.cjs is ignored ("couldn't find an eslint.config.* file").

   Candidate	Result	Reason
   9.37.0	Verified	Independently verified

3. ESLint: Flat config is the default

   ESLint 9 reads eslint.config.* and ignores .eslintrc.* unless ESLINT_USE_FLAT_CONFIG=false.

   Evidence: Migration guide (eslint.org/docs/latest/use/configure/migration-guide) · Observed failure ("couldn't find an eslint.config.(js|mjs|cjs) file")

4. Rewrote 1 call site

   .eslintrc.cjs:1

   − .eslintrc.cjs (legacy config)

   + eslint.config.cjs (flat config, fixupConfigRules)

5. Validated with 1,212 tests

   Each check ran on the unmodified repository first; only checks that pass there judge the change.

   test (22.x)	ci.yml	Passed	5 min
   typecheck	ci.yml	Passed	1 min
   lint	ci.yml	Passed	1 min

8. Waiting for a person to merge

   Converted .eslintrc.cjs with ESLint's own @eslint/migrate-config; lint and tests pass. Draft PR waiting for review.
