Find directly blocked issues via 'blocks' dependencies\n 2. Recursively propagate blockage to descendants (max depth: 50)\n 3. Exclude all blocked issues from results\n\n## CPU Profile Analysis\n\n- Database syscalls (pthread_cond_signal, syscall6): ~75%\n- SQLite engine overhead: inherent to recursive CTE\n- Application code (query construction): \u003c1%\n\n**Bottleneck is the recursive CTE query execution, not application code.**\n\n## Optimization Recommendations\n\n### High Impact (Likely to achieve \u003c50ms target)\n\n1. **Cache blocked issue calculation**\n - Add `blocked_issues` table updated on dependency changes\n - Trade write complexity for read speed (ready called \u003e\u003e dependency changes)\n - Eliminates recursive CTE on every read\n\n2. **Add/verify database indexes**\n ```sql\n CREATE INDEX IF NOT EXISTS idx_dependencies_blocked \n ON dependencies(issue_id, type, depends_on_id);\n CREATE INDEX IF NOT EXISTS idx_issues_status \n ON issues(status);\n ```\n\n### Medium Impact\n\n3. **Reduce allocations** (167K allocations for GetReadyWork)\n - Profile `scanIssues()` for object pooling opportunities\n - Reuse slice capacity for repeated calls\n\n### Low Impact (Not recommended)\n- Query optimization for CRUD operations (already \u003c3ms)\n- Connection pooling tuning (not showing in profiles)\n\n## Verification\n\nRun benchmarks to validate optimization:\n```bash\nmake bench-quick\ngo tool pprof -http=:8080 internal/storage/sqlite/bench-cpu-*.prof\n```\n\nProfile files automatically generated in `internal/storage/sqlite/`.","status":"tombstone","priority":0,"issue_type":"bug","created_at":"2025-11-14T09:02:46.507526-08:00","updated_at":"2025-12-25T01:21:01.952723-08:00","deleted_at":"2025-12-25T01:21:01.952723-08:00","deleted_by":"batch delete","delete_reason":"batch delete","original_type":"bug"} {"id":"bd-5r5md","title":"test","status":"closed","priority":2,"issue_type":"task","created_at":"2026-01-10T19:26:53.245563-08:00","created_by":"beads/crew/dave","updated_at":"2026-01-10T19:27:06.494897-08:00","closed_at":"2026-01-10T19:27:06.494897-08:00","close_reason":"Closed"} {"id":"bd-5rj1","title":"Merge: bd-gqxd","description":"branch: polecat/furiosa\ntarget: main\nsource_issue: bd-gqxd\nrig: beads","status":"closed","priority":2,"issue_type":"merge-request","created_at":"2025-12-23T16:40:21.707706-08:00","updated_at":"2025-12-23T19:12:08.349245-08:00","closed_at":"2025-12-23T19:12:08.349245-08:00"} +{"id":"bd-5rlsy","title":"Session ended: gt-beads-refinery","status":"closed","priority":2,"issue_type":"event","owner":"steve.yegge@gmail.com","created_at":"2026-01-11T20:07:23.717739-08:00","created_by":"beads/refinery","updated_at":"2026-01-11T20:07:23.781498-08:00","closed_at":"2026-01-11T20:07:23.781498-08:00","close_reason":"auto-closed session cost wisp","ephemeral":true} {"id":"bd-5s91","title":"CLI API Audit for OSS Launch","description":"Comprehensive CLI API audit before OSS launch.\n\n## Tasks\n1.
