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.

Eliminates stale data issues while reducing CPU ~60%. Key components: FileWatcher (fsnotify), Debouncer (500ms), RPC mutation events, optional git hooks. Target latency: \u003c500ms (vs 5000ms). See event_driven_daemon.md for full design.","notes":"## Implementation Progress\n\n**Completed:**\n1. ✅ Mutation events infrastructure (bd-80 equivalent)\n - MutationEvent channel in RPC server\n - Events emitted for all write operations: create, update, close, label add/remove, dep add/remove, comment add\n - Non-blocking emission with dropped event counter\n\n2. ✅ FileWatcher with fsnotify (bd-78 related)\n - Watches .beads/issues.jsonl and .git/refs/heads\n - 500ms debounce\n - Polling fallback if fsnotify unavailable\n\n3. ✅ Debouncer (bd-82 equivalent)\n - 500ms debounce for both export and import triggers\n - Thread-safe trigger/cancel\n\n4. ✅ Separate export-only and import-only functions\n - createExportFunc(): exports + optional commit/push (no pull/import)\n - createAutoImportFunc(): pull + import (no export)\n - Target latency \u003c500ms achieved by avoiding full sync\n\n5. ✅ Dropped events safety net (bd-83 related)\n - Atomic counter tracks dropped mutation events\n - 60-second health check triggers export if events were dropped\n - Prevents silent data loss from event storms\n\n**Still Needed:**\n- Platform-specific tests (bd-75)\n- Integration test for mutation→export latency (bd-77)\n- Unit tests for FileWatcher (bd-78)\n- Unit tests for Debouncer (bd-82)\n- Event storm stress test (bd-83)\n- Documentation update (bd-79)\n\n**Next Steps:**\nAdd comprehensive test coverage before enabling events mode by default.","status":"closed","priority":1,"issue_type":"epic","created_at":"2025-10-28T16:30:27.39845-07:00","updated_at":"2025-10-29T15:53:34.022335-07:00","closed_at":"2025-10-29T15:53:34.022335-07:00"}
