Epic P7. Locks in the epic's gains with ESLint gates so the adoption work
does not regress.
- ccs/no-new-throw-error (error): custom flat-config rule that flags NEW
throw new Error(...) outside a generated baseline allowlist. Forces the
typed-error taxonomy (src/errors/error-types.ts). Existing 338 sites are
grandfathered in eslint-rules/throw-error-baseline.json; only NEW violations
error. Rule normalizes the filename to repo-root-relative to match baseline
keys regardless of how ESLint reports paths.
- max-lines (warn, 400, skipBlankLines/skipComments): warns on files over
400 LOC (goal of P5/P6 god-file splits). Currently 51 warnings on the
not-yet-split god-files (P6 territory).
- scripts/generate-throw-error-baseline.js: emits the allowlist from raw
source (superset of real throws; never undercounts). Run after intentionally
grandfathering a site, or quarterly to prune.
- tests/unit/eslint-rules/no-throw-new-error.test.ts: rule logic (flags
off-allowlist, passes on-allowlist/typed/rethrow, line-sensitivity).
- docs/code-standards.md: Lint Enforcement Gates section.
- docs/logging-contract.md: error.code -> ExitCode table (from P4).
