# Production Quality Requirements Checklist: Background Indexing for Large Repositories **Purpose**: Validate requirements quality for production-grade background indexing feature **Created**: 2025-10-17 **Feature**: [spec.md](../spec.md) **Domain**: Production Quality & Reliability ## Checklist Methodology This checklist tests **requirements writing quality**, not implementation correctness. Each item validates that the specification itself is complete, clear, consistent, measurable, and unambiguous. **Scoring**: - ✅ **PASS**: Requirement meets quality standard - ⚠️ **WARN**: Requirement needs minor clarification or improvement - ❌ **FAIL**: Critical gap or ambiguity requiring spec revision --- ## 1. Requirement Completeness ### 1.1 Lifecycle Coverage - [ ] **Are all 6 job lifecycle states clearly defined with descriptions?** - Referenced: FR-004 (pending, running, completed, failed, cancelled, blocked) - Test: Can a developer implement state transitions without asking "what does 'blocked' mean?" - Gap Check: Are state transition rules specified? (e.g., can cancelled → running?) - [ ] **Are state transition rules documented for all valid/invalid transitions?** - Referenced: Key Entities - Background Job invariants - Test: "Job cannot transition from completed/failed/cancelled states back to running" - Gap Check: What about pending → blocked? running → blocked? - [ ] **Are all error scenarios identified with recovery behavior?** - Referenced: Edge Cases (database loss, embedding service outage, storage exhaustion) - Test: Each edge case includes "What happens when" + resolution - Gap Check: Missing scenarios? (network errors, permission errors, corrupted files) ### 1.2 Performance Requirements - [ ] **Are all performance metrics quantified with specific targets?** - Referenced: FR-002 (1s), FR-006 (100ms), FR-007 (200ms), FR-008 (5s), FR-009 (10s) - Test: No vague terms like "fast", "quickly", "responsive" - Gap Check: Missing metrics? (checkpoint write latency, queue wait time) - [ ] **Are performance requirements consistent across all sections?** - Cross-reference: FR-001 (60s trigger) vs A-002 (60s threshold) vs SC-006 (constitutional 60s target) - Test: All 3 references use same 60-second value - Gap Check: Any conflicting timing values? - [ ] **Are performance degradation scenarios addressed?** - Referenced: FR-011 (3 concurrent jobs without degradation), SC-006 - Test: Spec defines what "without degradation" means (each job meets same targets) - Gap Check: What happens with 4+ concurrent jobs? (queued - FR-011 acceptance criteria) ### 1.3 Recovery & Resilience - [ ] **Are checkpoint frequency requirements specified?** - Referenced: FR-010 (<1% duplicate work), User Story 4 Scenario 2 - Test: Measurable outcome defined (1% threshold) - Gap Check: Is checkpoint frequency interval specified? (Not in spec, deferred to implementation) - [ ] **Are automatic recovery requirements complete?** - Referenced: FR-009 (auto-resume within 10s), FR-010 (checkpoint-based recovery) - Test: All aspects covered (detection, resumption timing, duplicate prevention) - Gap Check: What if database corruption? (Not specified - edge case missing?) - [ ] **Are failure recovery requirements defined for all edge cases?** - Referenced: Edge Cases (6 scenarios with recovery behavior) - Test: Each edge case includes expected outcome - Gap Check: All edge cases have actionable resolution (yes - pause/retry, cleanup, etc.) --- ## 2. Requirement Clarity ### 2.1 Terminology Consistency - [ ] **Is terminology used consistently throughout?** - Test: "background job" vs "background operation" vs "async task" vs "indexing task" - Review: FR-001 (operation), FR-002 (operation), FR-004 (operation), Key Entities (Background Job), User Stories (task) - Finding: Minor inconsistency - "operation" in FRs, "job" in entities, "task" in stories - [ ] **Are all domain terms defined before use?** - Check: "Background Job", "Job Checkpoint", "Job Event" defined in Key Entities - Test: First use of each term has definition or reference - Gap Check: "MCP client timeout" used in FR-001 - defined in A-001 (good) ### 2.2 Ambiguity Detection - [ ] **Are all [NEEDS CLARIFICATION] markers resolved?** - Count: 3 markers in initial draft - Status: All 3 resolved in Clarifications section (Session 2025-10-17) - Test: Search spec for remaining markers (none found) - [ ] **Are requirements unambiguous with single valid interpretation?** - FR-005 test: "every 10 seconds or every 100 work units completed, whichever occurs first" - Analysis: Clear - uses specific numbers and precedence rule (whichever first) - FR-008 test: "stops gracefully within 5 seconds" - Analysis: Potential ambiguity - what if can't stop gracefully? (Acceptance criteria clarifies: "completes current batch") - [ ] **Are all acceptance criteria objectively testable?** - FR-010: "<1% of work is repeated after restart" - Test: Yes - can measure files processed before/after restart and calculate percentage - SC-008: "95% of users understand job status" - Test: Measurable but requires user study (acceptable for UX success criteria) ### 2.3 Prerequisite Clarity - [ ] **Are all prerequisites and dependencies identified?** - Referenced: Assumptions section (A-003: Ollama embedding service), Scope Clarity checklist - Test: Dependencies listed (database, embedding service, existing indexing logic) - Gap Check: Missing dependencies?
