WP-040 — overfit-100 on an accelerator¶
Train-set recall 0.9747 against the 0.95 floor, MPS, 4:47 wall clock, decoded NMS-free through the deployed path.
The structural decision that outlived it: goldens/gpu/ is excluded from default harness discovery and recomputed only under --include-gpu, which is what keeps the offline gate accelerator-free while still holding accelerator numbers under version control. The cost of that split is that a gpu/ golden can go stale unnoticed — shapes_regression_det.json currently has an outstanding re-freeze.
Superseded by WP-167. The outstanding re-freeze is closed: all five files under goldens/gpu/, shapes_regression_det.json among them, were regenerated on an L4. The sentence above is left as written because the staleness it predicted is exactly what happened — golden-gpu returned 46/48 on the pre-WP-169 values — and a log that edits its own correct predictions into the past tense stops being evidence that anything was predicted.
