Implement event-driven daemon improvements for bd-85

- Add mutation events for label/dep/comment operations - Create separate export-only and import-only functions - Add dropped events counter with safety net export - Complete bd-80 mutation channel implementation Event-driven mode now: - Emits mutation events for ALL write operations (not just create/update/close) - Uses createExportFunc() for mutations (export+commit/push only, no pull) - Uses createAutoImportFunc() for file changes (pull+import only, no export) - Tracks dropped events and triggers safety export every 60s if any dropped - Achieves <500ms latency target by avoiding full sync on each trigger Behind BEADS_DAEMON_MODE=events flag (poll is still default)

 {"id":"bd-8","title":"Daemon fails to auto-import after git pull updates JSONL","description":"After git pull updates .beads/issues.jsonl, daemon doesn't automatically re-import changes, causing stale data to be shown until next sync cycle (up to 5 minutes).\n\nReproduction:\n1. Repo A: Close issues, export, commit, push\n2. Repo B: git pull (successfully updates .beads/issues.jsonl)\n3. bd show \u003cissue\u003e shows OLD status from daemon's SQLite db\n4. JSONL on disk has correct new status\n\nRoot cause: Daemon sync cycle runs on timer (5min). When user manually runs git pull, daemon doesn't detect JSONL was updated externally and continues serving stale data from SQLite.\n\nImpact:\n- High for AI agents using beads in git workflows\n- Breaks fundamental git-as-source-of-truth model\n- Confusing UX: git log shows commit, bd shows old state\n- Data consistency issues between JSONL and daemon\n\nSee WYVERN_SYNC_ISSUE.md for full analysis.","design":"Three possible solutions:\n\nOption 1: Auto-detect and re-import (recommended)\n- Before serving any bd command, check if .beads/issues.jsonl mtime \u003e last import time\n- If newer, auto-import before processing request\n- Fast check, minimal overhead\n\nOption 2: File watcher in daemon\n- Daemon watches .beads/issues.jsonl for mtime changes\n- Auto-imports when file changes\n- More complex, requires file watching infrastructure\n\nOption 3: Explicit sync command\n- User runs `bd sync` after git pull\n- Manual, error-prone, defeats automation\n\nRecommended: Option 1 (auto-detect) + Option 3 (explicit sync) as fallback.","acceptance_criteria":"1. After git pull updates .beads/issues.jsonl, next bd command sees fresh data\n2. No manual import or daemon restart required\n3. Performance impact \u003c 10ms per command (mtime check is fast)\n4. Works in both daemon and non-daemon modes\n5. Test: Two repo clones, update in one, pull in other, verify immediate sync","notes":"**Current Status (2025-10-26):**\n\n✅ **Completed (bd-128):**\n- Created internal/autoimport package with staleness detection\n- Daemon can detect when JSONL is newer than last import\n- Infrastructure exists to call import logic\n\n❌ **Remaining Work:**\nThe daemon's importFunc in server.go (line 2096-2102) is a stub that just logs a notice. It needs to actually import the issues.\n\n**Problem:** \n- importIssuesCore is in cmd/bd package, not accessible from internal/rpc\n- daemon's handleImport() returns 'not yet implemented' error\n\n**Two approaches:**\n1. Move importIssuesCore to internal/import package (shares with daemon)\n2. Use storage layer directly in daemon (create/update issues via Storage interface)\n\n**Blocker:** \nThis is the critical bug causing data corruption:\n- Agent A pushes changes\n- Agent B does git pull\n- Agent B's daemon serves stale SQLite data\n- Agent B exports stale data back to JSONL, overwriting Agent A's changes\n- Agent B pushes, losing Agent A's work\n\n**Next Steps:**\n1. Choose approach (probably #1 - move importIssuesCore to internal/import)\n2. Implement real importFunc in daemon's checkAndAutoImportIfStale()\n3. Test with two-repo scenario (push from A, pull in B, verify B sees changes)\n4. Ensure no data corruption in multi-agent workflows","status":"in_progress","priority":0,"issue_type":"epic","created_at":"2025-10-25T23:13:12.270766-07:00","updated_at":"2025-10-27T22:22:23.815209-07:00"}
