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.

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.
