# Specification quality: Independent Kavita provider services

**Created**: 2026-10-22
**Feature**: [spec.md](../spec.md)

- [x] User scenarios define observable outcomes and independent checks.
- [x] Requirements cover requested metadata, recommendations, reviews and sync.
- [x] Missing capabilities and credential dependencies are explicit.
- [x] Acceptance distinguishes source, fixture, image and live proof.
- [x] Preservation, privacy, rollback and unsupported-provider behavior are defined.
- [x] Full parity is a completion criterion rather than an unsupported claim.

- [x] US4 covers protected deletion, cooldowns, provider/action isolation, outage retention and confirmed delivery.
- [x] FR-014–018 map to source and executable acceptance in the hardening review.
- [x] Follow-up history distinguishes implementation-time specification from earlier requirements.
- [x] Reread/reset and genuine account acceptance remain explicit limits.

This checklist assesses requirement quality. Rollout and implementation evidence are recorded separately in tasks and validation. No `.specify/extensions.yml` is registered in this checkout.

- [x] FR-019–021 define credential-clear retention, cold-process outage retention and bounded storage behavior.
- [x] Protected/legacy receipts and ambiguous reservations cannot be retired by time-only cleanup.
- [x] Full capacity holds events and refuses protected writes before provider mutation.
- [x] Snapshot binding, corruption refusal, capability revocation and failed-save limitations are specified.
