+## 2026-07-27 - Dated imagery corpus v4 and loop continuation
+
+- Added governed, detection-capable fixed products for SPW Orthophotos 2024,
+  Digitaal Vlaanderen 2025 and its official Brussels coverage. Rolling
+  `latest` mosaics are no longer used by the training provisioner.
+- Expanded the corpus to 75 AOIs, with 15 training AOIs per region and the
+  protected validation/calibration/test/background composition unchanged.
+- Frozen corpus `building-be-v4-dated-20260727-r1` contains 13,765 accepted
+  labels from 13,899 inputs. Manifest SHA-256 is
+  `32f0c969e3131da33497ebffb6782ddf1b58e83b8a46f929818c2140af867fd3`.
+  Spatial leakage passed and temporal-unknown samples fell from 60 to zero.
+- Iteration 2 improved fixed-IoU test F1 from `0.375` to `0.419`; regional F1
+  became Brussels `0.566`, Wallonia `0.427`, Flanders `0.222`. The generic-base
+  iteration did not beat it. Both remained rejected, and iteration 4 started
+  from the stronger candidate on the dated 75-AOI corpus.
