cd-ogi-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.

Exact revision 9475f96c32dd4764471e4358ca6659b0dd348ecd. Pinned source license declares CC BY 4.0; a source metadata JSON separately declares CC0. The unresolved discrepancy is retained; this audit elects CC BY 4.0 and makes no public-domain claim. See ATTRIBUTION.md, LICENSE and CC BY 4.0 terms. No endorsement is implied.

Changes: prospectively selected 42 pairs; recording-disjoint development roles; nonzero binary mask occupancy; fractional training targets and native-resolution confusion counts; CSV transfer of the frozen source IDs and CPU results. Filenames, source hashes, bytes and publisher counts are retained. No copied article or image payload is in this audit repository. The related model's original cloud archive retains the qualified PNG subset with its source notices and separate dependency grants.
