Complete Phase 4 (User Story 2) - AI-Powered Feedback Analysis
Verification revealed Phase 4 was 96% complete (27/28 tasks). Implemented missing retry logic (T081) and marked all tasks as complete in tasks.md. Implementation Status: - Tests (T065-T070): ✅ 6/6 complete - 5 unit tests for AIAnalyzer interface and extraction methods - 2 integration tests for full analysis flow - All tests passing - Core Implementation (T071-T092): ✅ 22/22 complete - AIAnalyzer abstract base class with interface - AnalysisResult dataclass for structured results - ClaudeAnalyzer with Anthropic SDK integration - Single-call prompt design (categorize + summarize + translate) - Language detection and category extraction - Summary and translation extraction with regex - 45s API timeout handling - NEW: Retry logic with exponential backoff (3 retries, 1s/2s/4s) - Retries transient errors (rate limits, server errors) - Does not retry timeouts or non-retryable errors - Analysis storage to analysis.md - Background threading for async analysis - Automatic trigger on feedback submission - Status transitions: new → analyzing → analyzed/analysis_failed - Language and category stored in metadata.yaml - ANTHROPIC_API_KEY documented in .env.example - FR-016 compliance: Original content.txt preserved - FR-021 compliance: Images stored but not OCR'd New Implementation: - Added retry logic for transient API failures (T081): - Max 3 retries with exponential backoff (1s, 2s, 4s) - Only retries rate limits and server errors - Does not retry timeouts or permanent errors - File: app/services/ai_analyzer.py lines 70-123 Test Results: - 8 tests passed (unit + integration + contract) - All analysis features verified working - Manual analysis trigger tested - Background analysis tested - Error handling and status transitions verified Integration Points: - Automatic analysis on submission (app/routes/submission.py:93-94) - Manual analysis trigger (app/routes/dashboard.py:207-285) - Analysis storage (app/services/feedback_storage.py:476-548) - Status management throughout analysis lifecycle 🎯 CHECKPOINT: User Stories 1 AND 2 work together seamlessly - feedback is submitted AND automatically analyzed with categorization, summarization, and translation. Manual re-analysis also available via dashboard. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
