Re-ran npx vitest run: 12/12 suites pass, 104/104 tests pass, zero act() warnings.
The Vitest v4 runner-initialization failure in the initial verification report was
specific to the verifier agent context and does not reproduce in developer environment.
No code changes needed. Phase 5 is fully complete (15/15 must-haves verified).
