Sector-residual deep test (masked, repaired snapshot)
Generated: 2026-07-19T11:33:19.102779
SURVIVORSHIP BIAS: today's constituents backfilled. Relative IC only — not levels.
Pre-registered grade (mechanical)
Verdict: FAIL
Task 1 CLOSED — sector residual dead on deep evidence.
Reason: failed one or more pre-registered checks (see checks)
