# Specification Quality Checklist: Spec 405 - JSON-to-JSONB Data-layer Hardening
**Purpose**: Validate specification completeness and quality before implementation preparation is handed off.
**Created**: 2026-06-23
**Feature**: `specs/405-json-to-jsonb-data-layer-hardening/spec.md`
## Content Quality
- [x] Focused on product value, operator trust, and data-layer hardening risk.
- [x] No application implementation is performed by this preparation package.
- [x] Runtime implementation details are limited to expected migration/test/validation surfaces.
- [x] Mandatory Spec Kit sections are completed or explicitly marked N/A with rationale.
- [x] Scope excludes new product behavior, UI surfaces, authorization model changes, lifecycle semantics, and broad abstractions.
## Requirement Completeness
- [x] No unresolved clarification markers remain.
- [x] Requirements are testable and unambiguous.
- [x] Success criteria are measurable.
- [x] Acceptance scenarios are defined for inventory, conversion, and regression/reporting.
- [x] Edge cases are identified, including `jsonb` key order normalization and rollback limitations.
- [x] Dependencies and assumptions are identified.
- [x] Required final implementation report structure is defined.
## Feature Readiness
- [x] Functional requirements map to concrete tasks in `tasks.md`.
- [x] User stories cover the minimum viable implementation sequence.
- [x] The plan identifies likely affected repository surfaces without authorizing unrelated runtime edits.
- [x] Tasks include tests, PostgreSQL validation, focused browser proof, staging-like validation handling, and final close-out.
## Constitution And Product Surface Readiness
- [x] Spec Candidate Check is completed with approval class, score, and decision.
- [x] Completed-spec guardrail is explicit and related specs are read-only context.
- [x] No UI surface impact is checked with a clear rationale.
- [x] Product Surface Contract is handled as no-rendered-surface-change plus focused regression proof.
- [x] Browser verification is required as backend regression proof for existing payload-backed surfaces.
- [x] Human Product Sanity is scoped to unchanged trust semantics.
- [x] Proportionality review states no new runtime framework, persisted entity, status family, or UI taxonomy.
- [x] Test governance names PostgreSQL, feature, and focused browser lanes with fixture-cost controls.
## Notes
Preparation review result: pass. The package is ready for a separate implementation loop, provided the implementation agent completes the inventory matrix before writing migrations and preserves the no-product/no-UI boundary.
