-{"id":"gt-o3is","title":"gt sling pinToHook doesn't set pinned boolean field","description":"## Bug\n\nWhen `gt sling` pins work to an agent's hook via subprocess, `bd pin` reports success but the `pinned` boolean field is NOT persisted.\n\n## Root Cause (Found 2025-12-23)\n\nThe issue is a sync/flush timing problem:\n\n1. `gt sling` calls `pinToHook()` which runs `bd --no-daemon pin`\n2. `bd pin` updates the SQLite database with `pinned=1`\n3. `bd pin` schedules a flush to JSONL (via FlushManager)\n4. Subprocess exits BEFORE flush completes\n5. `gt sling` then calls `syncBeads()` which runs `bd sync`\n6. `bd sync` imports from JSONL which DOESN'T have pinned field\n7. Import overwrites SQLite, resetting `pinned=0`\n\nThe assignee field IS set correctly because it's also in the database before sync, but sync imports the JSONL which doesn't have the pinned field (due to omitempty on false value).\n\n## Reproduction\n\n```bash\n# Create issue\nbd create \"test\" --json\n\n# Sling it\ngt sling \u003cid\u003e gastown/crew/max\n\n# Check - pinned is null!\nbd show \u003cid\u003e --json | jq '.[0].pinned'\n```\n\n## Fix Options\n\n1. **Make bd pin synchronous**: Force flush before subprocess exit\n2. **Skip sync after pin**: Don't call syncBeads after pinToHook\n3. **Use direct DB update in gt**: Call UpdateIssue directly instead of bd subprocess\n4. **Fix flush-on-exit**: Ensure PersistentPostRun waits for flush completion\n\n## Workaround\n\nThe handoff bead attachment (`AttachMolecule`) is the primary mechanism for tracking what's on an agent's hook. The pinned field is cosmetic for `bd hook` visibility.\n\n## Files\n\n- gastown: internal/cmd/sling.go (slingToCrew, pinToHook, syncBeads)\n- gastown: internal/beads/beads.go (Pin method)\n- beads: cmd/bd/pin.go (bd pin command)\n- beads: cmd/bd/flush_manager.go (async flush)","status":"open","priority":1,"issue_type":"bug","created_at":"2025-12-23T04:41:12.668958-08:00","updated_at":"2025-12-23T12:03:22.343937-08:00"}
+{"id":"gt-o3is","title":"gt sling pinToHook doesn't set pinned boolean field","description":"## Updated Root Cause Analysis (2025-12-23)\n\nThe issue is **NOT** in gt as originally thought. It's in the beads (bd) codebase.\n\n### What happens:\n1. `bd pin` correctly sets pinned=1 in SQLite\n2. Any subsequent `bd` command (even `bd show`) resets pinned to 0\n3. This happens even with `--no-auto-import` and `--sandbox` flags\n\n### Evidence:\n```bash\n$ bd --no-daemon pin gt-k08o --for=max\n📌 Pinned gt-k08o to max's hook\n\n$ sqlite3 beads.db 'SELECT id, pinned FROM issues WHERE id=\"gt-k08o\"'\ngt-k08o|1   # ← Correct immediately after pin\n\n$ bd --no-daemon --no-auto-import show gt-k08o\n[shows issue without pinned field]\n\n$ sqlite3 beads.db 'SELECT id, pinned FROM issues WHERE id=\"gt-k08o\"'  \ngt-k08o|0   # ← WRONG\\! bd show overwrote it\n```\n\n### Where to look:\nThe bug is likely in one of these beads code paths:\n- Some import/hydration running despite --no-auto-import\n- WAL mode not flushing before subsequent reads\n- Multi-repo or redirect handling corrupting pinned field\n\n### Workaround:\nThe handoff bead attachment mechanism (AttachMolecule) works correctly.\nThe pinned field is cosmetic for `bd hook` visibility only.\ngt sling correctly uses AttachMolecule for work assignment.\n\n### Next steps:\nCreate a beads issue to fix this properly in the bd codebase.\nThis is not a gt issue.","notes":"Created beads bug: bd-phtv in ~/gt/beads","status":"open","priority":1,"issue_type":"bug","created_at":"2025-12-23T04:41:12.668958-08:00","updated_at":"2025-12-23T12:32:43.506087-08:00"}
