T2: the maker species is real and distinct — 673 wallets clear the taker
screen's z>=2.5 discipline on the orders_matched stream (~33 expected by
chance), pooled +$5.9M over 47,693 resolved bets in ~6 tape days; only
96/673 overlap the taker informed set, 3/37 watch_sharps. Not copyable by
taking (their edge IS the spread) — follow-ons: inventory-lean signal,
T1 generic maker sim.
T4: print-substrate sibling-sum scan reads 2.8%/1.5% violation minutes but
the top examples expose the artifact (resolution-time dust prints at bids,
not standing offers); persistence p50 1min. Verdict: inconclusive at v0,
needs standing-book data (L2 recording / live paired scanner) — parked
behind the T1 decision.
