Add v44 Flemish corpus expansion

   narrowly from `0.525` to `0.496`. Added a `0.03` precision/recall sampling
   guard-band so a just-passing region retains stabilizing evidence while the
   hard-failing region remains the primary target (`21 passed`).
+- Iterations 5 and 6 confirmed that the guard-band retains Wallonia above its
+  gates, but Flanders remains structurally below precision, recall and F1
+  gates. Stopped iteration 7 before its first result row and freed the GPU
+  rather than repeating the same evidence. Added 12 independent v44 Flemish
+  acquisition targets across coastal, industrial, ribbon, dunes, port and
+  farmland-hard-negative contexts for the next immutable corpus wave.
