Authoritative report history-depth-20260719-103315: race guard pass on deep
research.sqlite. Sector residual still short-window only (no pre-2021); fip sign
flips on broad deep sample; no production retune.
Tier-1 alpha research (local only, no production deploy):
Sector residual momentum: two-factor SPY+sector residual and sector demean signals, IC harness + A/B. Sector resid clears pre-registered bars narrowly (PROMOTE for human wire design only). Sector demean fails t vs market resid.
Earnings: earnings_events backfill (FMP bulk paid; FMP/AV per-symbol), 2a gap diagnostic report-only, 2b SUE IC (PARK; incomplete 48/506 coverage).
History-depth: pre-registered doc + runner for MacBook deep rebuild/harness.
Do not ship production residual or filters from this branch.
