| # Controlled Diet recording/mask audit |
|
|
| **137 audit rows describe 42 selected source images in nine recording IDs.** |
| They are not 137 images, independent releases, chemical measurements or gas-free |
| sessions. This native CSV dataset transfers the reviewed frozen CPU JSON records; |
| it adds no source pixel access, scoring, fitting or model selection. |
|
|
| | Configuration | Development roles | Rows | |
| |---|---|---:| |
| | recording_manifest | development_train / development_tune / development_compare | 18 / 12 / 12 = 42 | |
| | compare_frames | development_compare | 12 filenames × 7 frozen arms = 84 | |
| | candidates | development_tune | All 11 candidates, including the six learned fits | |
| |
| `recording_manifest` exposes original filenames, recording IDs, source paths/full |
| LFS SHA256/bytes, dietary class IDs and publisher foreground counts. Original |
| publisher splits are descriptive; the study assigns complete recording IDs to |
| disjoint development roles. `recording_selection.json` contains the same minimal |
| 42 row records. Source dietary IDs are not per-frame concentration measurements. |
| All source foreground counts are positive; physical-release independence is unknown. |
|
|
| `compare_frames` exposes native 640×480 integer TP/FP/FN/TN and original nullable |
| IoU/Dice/precision/recall/`background_pixel_overprediction_ratio`. Counts refer to |
| publisher-generated nonzero masks. Undefined metrics are empty CSV cells, not zero. |
| The background-pixel ratio FP/(FP+TN) is weak-reference pixel overprediction; it is |
| never a gas false-alarm rate, gas-absence score or count of negative recording sessions. |
| Primary aggregation is equal-weight recording means of frame IoU, as defined in |
| `protocol.json`; these rows are per-frame evidence, not a new pooled selection rule. |
|
|
| `candidates` retains completed outcomes, frozen selection flags, L2/step counts, |
| objective endpoints/trace counts and tune recording-macro IoU. Baselines' undefined |
| training objectives/L2 are empty cells. Comparison did not retune/refit/promote. |
| The spatial prior comparison IoU is 0.138078, tiny MLP 0.026416, logistic 0.022555: |
| both learned models lose. No industrial pipeline integration or field/chemical/device |
| qualification is provided. All roles remain exploratory `development_*` roles. |
