Constraint (★): the XmR validator's verdict math is unsound. Verified in code: min_sample_impressions is pre-registered on every experiment but read by zero lines; CTR is fed to XmR as a daily mean-of-ratios. The RFD flagging
Constraint (★): the XmR validator's verdict math is unsound. Verified in code: min_sample_impressions is pre-registered on every experiment but read by zero lines; CTR is fed to XmR as a daily mean-of-ratios. The RFD flagging this (specs/RFD-gsc-verdict-math-sparse-ctr.md) has been Open since 2026-05-24, and its "pause the cron if you don't fix it" escape clause was never followed — validate-experiments.yml has committed verdicts daily for 51 days.
This has propagated into the biggest decision in the repo: GDA's 2026-07-14 S4 all-in fired on a baseline center of 0.054 clicks/day vs test weeks of 1.43/1.00/1.14 — roughly 8 clicks/week, with no volume floor on the promote gate. Re-check before building the page factory.
Also records a prod audit finding that corrects specs/gda-page-factory.md: its premise that the price-guide generator is "the gap to fill" is wrong — 430 price-guide, 336 compare and 85 best-* pages are already live.
No code changed.
