feat(SO-19): fuzzy title similarity endpoint#33
Merged
Conversation
Adds a static, non-expiring API key that enables external tools to access the Mesa API without relying on ephemeral per-run agent keys. Changes: - New --api-key <key> CLI flag (also MESA_API_KEY_EXTERNAL env) - Auth middleware checks the external key before DB lookup - External key resolves to a synthetic 'external' agent in context - New GET /api/v1/issues endpoint for listing all issues (with ?status= and ?limit= filters) - 3 new tests covering external key auth (valid, wrong value, not set) The external key is intended for orchestration tools, CI/CD pipelines, and external agents that need to create issues, read status, or post comments without being part of the internal agent roster. Usage: mesa --api-key my-secret-key -t enterprise 3001 curl -H 'Authorization: Bearer my-secret-key' http://localhost:3001/api/v1/issues
…similarity
Implements duplicate-detection endpoint per SO-19 acceptance criteria.
- New POST /api/v1/issues/similarity accepts {title} and returns
[{key, title, similarity_score}] for active (non-terminal) issues
above 0.70 normalized Levenshtein threshold, sorted desc by score.
- ListActiveIssueTitles DB method scans todo/in_progress/in_review/blocked issues.
- Unit tests cover exact match, near-match, below-threshold, empty DB,
terminal-issue filtering, sorted order, and missing-title 400.
