+# Specification Quality Checklist: LLM Table Translation Service
+
+**Purpose**: Validate specification completeness and quality before proceeding to planning  
+**Created**: 2026-05-08  
+**Updated**: 2026-05-08 (post-review)  
+**Feature**: [spec.md](../spec.md)
+
+## Content Quality
+
+- [x] No implementation details (languages, frameworks, APIs) leak into spec.md
+- [x] Focused on user value and business needs — translation workflow, dictionary management, scheduling for operational stakeholders
+- [x] Written for non-technical stakeholders — uses business terminology throughout
+- [x] All mandatory sections completed (User Scenarios, Clarifications, Requirements, Key Entities, Success Criteria, Assumptions, Access Control Matrix)
+
+## UX Consistency
+
+- [x] Functional requirements fully support all flows in ux_reference.md (Flows A–G, updated for Superset API execution)
+- [x] Error handling requirements match all 'Error Experience' scenarios (A–I) in ux_reference.md
+- [x] No requirements contradict the defined User Persona or Context
+- [x] UX principles (preview gates manual runs, traceability, graceful degradation, cost awareness) are reflected in functional requirements
+- [x] INSERT execution via Superset API is consistent across spec, UX, quickstart, and contracts
+
+## Requirement Completeness
+
+- [x] No [NEEDS CLARIFICATION] markers remain — all post-review ambiguities resolved in Clarifications sessions
+- [x] Requirements are testable and unambiguous — each FR describes a specific, verifiable behavior
+- [x] Success criteria are measurable — 15 SC items include specific percentages, time bounds, or coverage targets
+- [x] Success criteria are technology-agnostic (no implementation details)
+- [x] All acceptance scenarios are defined — 7 user stories with 41 total acceptance scenarios
+- [x] Edge cases are identified — 19 edge cases covering NULL values, missing tables, large datasets, concurrency, LLM failures, composite keys, dictionary duplicates, schedule overlaps, retention gap, Superset API errors, SQL injection
+- [x] Scope is clearly bounded — covers configuration, preview quality gate, execution via Superset API, history, dictionary management, feedback loop, and scheduling; dialect-aware SQL generation (PostgreSQL/Greenplum, ClickHouse)
+- [x] Dependencies and assumptions identified — 22 assumptions
+
+## Feature Readiness
+
+- [x] All functional requirements have clear acceptance criteria (mapped to user story acceptance scenarios)
+- [x] User scenarios cover primary flows: Configuration (P1) → Preview Quality Gate + Dictionary (P2) → Superset API Execution + Feedback + Scheduling (P3) → Audit (P4)
+- [x] Feature meets measurable outcomes defined in Success Criteria
+- [x] No implementation details leak into specification
+- [x] Feature aligns with existing ss-tools architecture patterns (plugin system, Superset integration, LLM provider, scheduler, notification, RBAC)
+- [x] Contradictions resolved: FR-023 (snapshot isolation), dictionary conflict model (overwrite/keep existing), preview model (quality gate), auto-insert for scheduled runs (after first successful manual run)
+- [x] New entities added: TranslationBatch, TranslationPreviewSession, TranslationPreviewRecord, MetricSnapshot
+- [x] Event model expanded: nullable run_id, terminal states (succeeded/partial/failed/cancelled/skipped), pre-run events
+- [x] Access control matrix defined with ownership constraints
+- [x] Dialect-aware SQL generation declared (PostgreSQL/Greenplum + ClickHouse, detected from Superset connection)
+- [x] Retention gap resolved: MetricSnapshot persistence before event pruning
+
+## Notes
+
+- Post-review session resolved 3 critical contradictions and 10+ medium gaps.
+- FR count: 49 | SC count: 15 | Key entities: 10 | Edge cases: 19
+- Preview model clarified as quality gate (not row-level approval for all rows).
+- INSERT execution standardized on Superset `/api/v1/sqllab/execute/` API.
+- All manual copy/paste SQL Lab references removed from spec, UX, quickstart, and contracts.
+- Specification is ready for the next phase (`/speckit.plan` re-validation or `/speckit.implement`).
