### Latest Update: Bulk File Import Cluster Assignment Bug Fix (2026-02-10)
**Critical Bug Fix: Files now correctly distributed across multiple clusters for same location**

Replacement in CLAUDE.md at line 631 [5.363912]

B:BD[2.608] → [2.608:672]

### Latest Update: File Modification Time Fallback (2026-02-07)

[2.608]

[6.4021]

**Problem:** When the same location appeared multiple times in the CSV with different date ranges, all files ended up in the **last cluster created** instead of being distributed across their respective clusters.
**Root Cause:** The `clusterIDMap` used only `LocationID` as the key, causing each new cluster for the same location to overwrite the previous one in the map.
**Example of Bug:**
```csv
A12,loc123,/path/2019,2019,8000,864
A12,loc123,/path/2020,2020,8000,180
A12,loc123,/path/2022,2022,8000,180
A12,loc123,/path/2024,2024,8000,549
```
- **Before fix:** 4 clusters created, ALL 1773 files go into 2024 cluster
- **After fix:** 4 clusters created, files distributed correctly (864 in 2019, 180 in 2020, etc.)
**Solution:** Changed map key from `LocationID` to composite key `LocationID|DateRange`.
**Modified:**
- `tools/bulk_file_import.go` (lines 125, 171-172, 183-184)
  - Line 125: Updated map comment to reflect composite key
  - Line 171-172: Store with `compositeKey := loc.LocationID + "|" + loc.DateRange`
  - Line 183-184: Retrieve with same composite key
**Impact:**
- ✅ **Data integrity restored:** Files now go to correct clusters
- ✅ **Multiple date ranges per location:** Now works correctly
- ✅ **No breaking changes:** Simple 3-line fix
- ✅ **Backwards compatible:** Single location CSV rows work identically
**Verification:**
```sql
SELECT
    l.name as location_name,
    c.name as cluster_name,
    COUNT(f.id) as file_count
FROM cluster c
JOIN location l ON c.location_id = l.id
LEFT JOIN file f ON f.cluster_id = c.id
WHERE l.name = 'A12'
GROUP BY c.id, l.name, c.name
ORDER BY c.name;
```
**Note:** Data previously imported with the buggy code will need to be re-imported to fix cluster assignments.
