# Source audit

| Source | Rows | License/terms | Pair type | Label method | Restrictions |
|---|---:|---|---|---|---|
| Blackline Atlas Sentinel-2 paired capture | 15 | Copernicus Sentinel data terms / internal derived capture | optical-to-optical | manual scenario labels converted to reporter JSON | Verify redistribution terms; low spatial resolution |
| GabeT29/BRIGHT-XView2Format via ChrisRPL/satellite-disruption-triage-aux-v2-2 | 144 | CC-BY-NC-4.0 | optical-to-SAR | BRIGHT mask/evidence mapping | Non-commercial; cross-modality artifacts possible |
| xBD-Ukraine local materialization from sda-kr/xbd-ukraine lineage | 47 | MIT | optical-to-optical | xBD/xView2 building labels aggregated to tile | Building-level labels are not VLM expert reports |

Excluded or capped sources: SEN12MSCR was not used because license status is unclear; generic natural disaster rows from the larger v2.1 BRIGHT corpus were not used except the human-caused explosion events; synthetic reasoning rows were excluded from train/eval.
