Three repositories have no unit tests (notification-outbox, notification-delivery-log, nip05-verification) #905

Gap

Three repositories have no unit tests — no spec file imports them:

• src/repositories/notification-outbox-repository.ts (162 lines)
• src/repositories/nip05-verification-repository.ts (140 lines)
• src/repositories/notification-delivery-log-repository.ts (96 lines)

Note the trap: test/unit/services/notification-outbox-service.spec.ts exists, but it stubs the repository (claimBatch, markDelivered, markFailed are all sinon stubs) — so the 162 lines of actual SQL in the repository are untested. The user, invoice, event, and invite-code repositories all have specs; these three don't.

How measured

Import graph over the suite: 175 spec files vs 325 src/**/*.ts files — zero spec files reference these three modules (the service spec references the repository only as a stubbed interface).

What's worth covering

• Outbox claimBatch semantics: batch claiming without double-delivery across workers
• markDelivered / markFailed state transitions and failure-count accounting
• nip05-verification-repository.listForAdmin filters (domain, verified, stale, minFailures, pagination) — new in feat(admin): add operations console for mirrors, workers, and NIP-05  #895 and already serving the admin API untested
• Delivery-log writes: what gets recorded on success vs failure
