The 07-15 live gate never made a real decision: live_session_favorable read
today's breadth_rvol from today's OWN setup_events rows, which only the
NIGHTLY labeler writes — always None intraday, fail-open every session (the
07-15 "validation block" was computed pre-guard on a zero-filled feature).
Worse, breadth_rvol was unit-corrupted: _session_context pooled all setup
versions and pm1 stores RAW cumulative premarket volume in relative_volume
(median ~261k) vs the ratio tracks (~0.8) — ~240/267 historical sessions'
breadth was actually median premarket volume, and plan 009's v1 RVOL fallback
was about to flip forward sessions to ratio units.
Fixes (TDD, 21 regime tests):
- breadth_rvol is now pm1-ONLY: median premarket volume — the dominant
historical source, unit-consistent, and strictly pre-open knowable.
- _live_breadth_rvol recomputes today's pm1 fires IN MEMORY from premarket
minute_bars (pure compute_premarket_setups, no insert); previous_close
falls back to the latest prior daily close when today's daily_bars row is
absent intraday (else the gap basis silently flips to the premarket open).
- _regime_reject: verdicts before 9:50 ET are PROVISIONAL (re-scored ~5 min;
ingest lag can truncate the premarket frame) and the first verdict at/after
9:50 is FINAL even when None — caps the scorer at a handful of runs/day
instead of ~78 on quiet days (hot-path stall guard). Throttle arithmetic
moved inside the fail-open try (naive/aware mixing must not escape).
- Live fit excludes breadth_rvol-NULL training rows (zero-fill taught a
"zero premarket volume" class the serve path can never produce).
Prod re-validation on the cleaned feature (regime_features rebuilt, scores
rewritten): regime_meta_v1 fire-weighted expR_delta +0.0570 (pre-registered
bar +0.05, n=2058, PASS — the contaminated +0.0965 was inflated), keeps 37%;
recent-80-session delta +0.149R/session (always −0.141 → gated +0.008).
First genuine live verdict 2026-07-16: UNFAVORABLE (pm breadth 612,819).
Known accepted skew: live scaled-IEX volumes vs nightly SIP tape — the
meta_live-vs-EOD comparison is the standing forward measure.
Also backfilled the missed 07-15 nightly job supervised (SIP refetch, 50 v1
+ 6 pm1 setups, SPY/QQQ ingest, regime row) — plan 009's accrual clock is
unbroken.
