- compute_diff() for comparing local vs cloud records
|
|
- --diff flag for diff reporting without sync
|
|
- --smart-sync flag for differential uploads
|
|
- --delete-orphans flag for removing orphan records

# Phase 5 Plan 1: Smart Sync Summary
|
|
|
|
**CloudKit differential sync with query_all() pagination, compute_diff() change detection, and --smart-sync flag for selective uploads**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** 6 min
|
|
- **Started:** 2026-01-10T16:02:53Z
|
|
- **Completed:** 2026-01-10T16:08:31Z
|
|
- **Tasks:** 2
|
|
- **Files modified:** 1
|
|
|
|
## Accomplishments
|
|
|
|
- Added `query_all()` method with pagination using continuationMarker for >200 records
|
|
- Added `compute_diff()` function returning new/updated/unchanged/deleted categorization
|
|
- Added `--diff` flag showing change report without importing
|
|
- Added `--smart-sync` flag for differential uploads (skips unchanged records)
|
|
- Added `--delete-orphans` flag for removing CloudKit records not in local data
|
|
- Added update operation handling with recordChangeTag conflict detection
|
|
- Added menu options 12 (Smart sync) and 13 (Smart sync + delete orphans)
|
|
|
|
## Task Commits
|
|
|
|
Each task was committed atomically:
|
|
|
|
1. **Task 1: Add change detection with diff reporting** - `0c74495` (feat)
|
|
2. **Task 2: Add differential sync with smart-sync flag** - `d9a6aa4` (feat)
|
|
|
|
## Files Created/Modified
|
|
|
|
- `Scripts/cloudkit_import.py` - Added query_all(), compute_diff(), sync_diff(), new flags
|
|
|
|
## Decisions Made
|
|
|
|
- New records use forceReplace (creates or replaces)
|
|
- Updated records use update operationType with recordChangeTag
|
|
- Conflict handling (409) retries with forceReplace after re-query
|
|
- Location comparison uses 0.0001 degree tolerance for lat/lng
|
|
- Orphan deletion requires explicit flag (safe by default)
|
|
- Field comparison ignores recordChangeTag and timestamps
|
|
|
|
## Deviations from Plan
|
|
|
|
None - plan executed exactly as written.
|
|
|
|
## Issues Encountered
|
|
|
|
None.
|
|
|
|
## Next Phase Readiness
|
|
|
|
- Smart sync infrastructure complete
|
|
- Ready for 05-02: Verification and record management
|
|
- --diff can verify CloudKit state before/after sync operations
