Optimization to avoid JSON unmarshalling when strings match exactly (common case).
Simple 1-line change instead of complex streaming rewrite for P3 issue.
- Add snapshotMetadata struct with version, timestamp, commit SHA
- Validate snapshots are <1 hour old, from compatible version
- Auto-cleanup stale snapshots from interrupted syncs
- All snapshot functions now write/validate metadata files
- Fixes issue where crash/kill -9 left stale snapshots
- Added getMultiRepoJSONLPaths() helper to enumerate all JSONL files
- Updated daemon_sync.go to capture/update snapshots for each repo
- Added TestMultiRepoDeletionTracking to verify fix
- Added TestMultiRepoSnapshotIsolation for isolation guarantees
Previously, deletion tracking only worked for single-repo mode because
snapshot operations were hardcoded to the primary JSONL path. This fix
ensures snapshots are managed per-repository in multi-repo mode.
- Add 3-way merge deletion tracking using snapshot files
- Create .beads/beads.base.jsonl and .beads/beads.left.jsonl snapshots
- Integrate into both sync.go and daemon_sync.go
- Add comprehensive test suite in deletion_tracking_test.go
- Update .gitignore to exclude snapshot files
This fixes the resurrection bug where deleted issues come back after
multi-workspace git sync. Uses the beads-merge 3-way merge logic to
detect and apply deletions correctly.
