- The v5 tile audit passed with zero blank positive tiles. The automated CUDA
loop started from the strongest prior candidate and will checkpoint every
train/calibrate/test/background assessment without promoting failed models.
## 2026-07-27 - Feature-level temporal mismatch filtering
- Added provider-native creation-time filtering for dated training imagery:
GRB `BEGINDATUM` and PICC `DATE_CREAT` are parsed with explicit UTC handling.
Buildings created after the image period are audited and excluded rather
than taught as labels for structures absent from the image.
- Frozen corpus `building-be-v6-temporal-20260727-r1` excludes 246 such temporal
mismatches, accepts 13,524 labels and retains all 75 independent AOIs.
Manifest SHA-256 is
`973828b453e6fbeb5c04aa567ddb615566d92825d8698654f5056d2997d382eb`.
- Composition, spatial leakage, temporal identity and positive-imagery QA pass.
The v6 train/calibration/test/background exports are ready for the next loop
checkpoint; the running v5 iteration remains evidence but cannot supersede
the cleaner v6 corpus.
