Question

On the board path, which factor makes a line's raw score <= MIN_RAW_FOR_SCALE -- team volume (volume_for), share, or efficiency (efficiency priors)? And what stack value does the guard in stacked_line discard for those men?

Prediction

Prereg research/scientist/prereg/2026-09-23T2158Z-h114-zero-factor.md: every M row is SHARE, zero VOLUME, zero EFF (falsifier: any EFF/VOLUME or touches >= 0.5). F2: >= half of M rows discard v >= 1.0.

Finding and verdict

MEASURED NOTHING FOR THE FORECAST LAYER, AND H-114'S RESCUE CLAIM IS VACUOUS. 22/22 raw<=MIN_RAW rows are share-stage zeros (touches <= 0.0082); volume and efficiency zero none, and the efficiency negative fixture (rates forced to 0) classes 469/469 as EFF, so the classifier could have said so. The stack the guard discards is 0.54 pts in total (max 0.04 per man): a later stage 'cannot rescue' a zero share because the trailing points it would rescue with are also zero. The points H-114's graded zero men scored are information absent from every trailing input -- elevations (H-259), QB regime (H-258), a stale locked build (H-260) -- not a volume, efficiency or stacking defect.

Reasoning

H-114 asserts no later stage can rescue a zero share; the forecast lane owns the stages after share (volume x efficiency x stack). Needed to know whether any of them zeroes or could un-zero a line.

Next action

Nothing further in the forecast layer for H-114. Its remaining work is the share model's handling of ~0-usage men who then play (6 model-stage men here) and the information rows already filed (H-258/259/260). Replaying at the locked wk2 sha a312a9e2 was not done: efficiency.py, MIN_RAW_FOR_SCALE and stacked_line are unchanged since then, and volume_for only lost its market term, so the factor answer should carry, but it is not measured on that build.
