Log the 21:14 orphan as a snapshot-build race, rewrite the context table to
authoritative ICs only, and soften the vol-tilt warning. Add extender completion
manifest + breadth refuse guard; strip intermediate/orphaned reports; park the
thread (no book sim, no deploy).
Add research-only snapshot extender, PIT dollar-volume mask for signal IC,
rank-only harness path, fingerprint+breadth runner, and docs. Fingerprint
reproduced IC -0.045 / t -2.91 on prod.sqlite. No production gate/schedule changes.
