Six new unit suites (102 tests) for the highest-risk untested libs:
userDataCleanup (destructive account/project deletes), documentVersions
(document integrity), chat/citations (legal-citation parsing), safeError
(secret redaction), llm/models (model resolution), and userLookup
(profile email sync). Coverage floors ratchet up 2/2/4/2 ->
11/10/14/10 (measured 11.18/10.98/14.43/10.91), and
docs/testing-coverage.md gives contributors a prioritized backlog for
the remaining untested libs.
