- package.json test script now covers test/ recursively + nrmse/errorMetric.
- Removed 5 broken test files that used Mocha-style describe()/it() globals
with no test runner installed. All 5 have working kebab-case node:test
equivalents (e.g. childRegistration.test.js → child-registration-utils.test.js).
- 4 remaining pre-existing assertion failures in output-utils + validation-utils
logged in OPEN_QUESTIONS.md for Phase 10.5.
166/170 tests pass (4 known pre-existing failures).
