Mirrors forward.py::score_oracle semantics verbatim (constants frozen from
study_oracle/tape); live-only suppress-only guards; $100 FAK walks the live
asks inside p_ref*1.05; three settle layers (own-feed tick, CLOB flags,
nightly CTF re-grade via grade_oracle.py -> oracle_paper_ledger.jsonl).
Shakedown 2026-07-22: 52 events/9 fills/43 craters at p50 541ms; 30/30
event agreement vs tape scorer on the comparable set. Verdict still binds
to forward_ledger only (#17).
