  "objective": "Bring kcd2_dice_solver/src/core/scoring.ts (361 lines) under the repo-wide 250-line file cap by extracting the move generator -- the enumeration of every legal single step from a position (straights, badge formations, n-of-a-kind, singles, and both joker rules) together with the n-of-a-kind value helpers -- into a sibling module, leaving Scorer with its caches and recursions, and proving Farkle scoring is unchanged with the project's own 288-test suite at 100% coverage.",
  "acceptance_criteria": [
    "scoring.ts and the new sibling module are each at most 250 lines, and check_file_length.sh --all no longer lists src/core/scoring.ts.",
    "npx vitest run still reports 24 files and 288 tests, all passing -- no test was added, deleted, or had an assertion weakened.",
    "npx vitest run --coverage still reports 100% statements, 100% branches, 100% functions and 100% lines, with the same 863/375/181/810 totals, since no statement is added or removed.",
    "npm run lint (tsc --noEmit && eslint src) still exits 0 with no output.",
    "Every importer of a moved symbol imports it from the module that now defines it, with no re-export barrel added to scoring.ts for the moved symbols. scoring.ts's pre-existing re-export of CATEGORIES/FACES/WILD_ALONE/WILD_COMBO/CountVector from counts.ts predates this change and stays as it is.",
    "Zero suppressions added: no eslint-disable, no @ts-ignore, no @ts-expect-error, and vite.config.ts is byte-identical (thresholds and exclude untouched)."
  ],
  "out_of_scope": [
    "Any change to the scoring rules themselves -- the doubling rule, the two joker rules, the Emperor/Tyche triple-only multipliers, the straight and badge-formation values, and the 'only a natural 1 or 5 scores alone' rule all keep their current semantics exactly.",
    "Changing Scorer's caching strategy or its public method set (score, scoreKey, scoreFaces, scoreUsingAll).",
    "Removing or altering scoring.ts's existing re-exports from counts.ts, which other modules rely on.",
    "Modifying vite.config.ts, including adding any new file to the coverage exclude list.",
    "Splitting badgeValue.ts or App.tsx -- each is its own separate commit.",
    "Wiring the file-length pre-commit hook -- it must land last."
