"""T1 EXPLORATORY (2026-07-23) — crypto maker quoting on the oracle feed.

Every taker study died at the requote wall (60-83% craters; makers repriced
in <4s). This sims BEING the maker: a resting bid pinned to oracle-fair
minus a margin, refreshed with latency R (the stale-quote window is the
risk), filled when a tape print crosses it, graded to chain truth.

Model per print at t: our active bid = fair(S(t-R), vol(t)) - m (vol drift
over R<=4s is negligible; S(t-R) is the staleness that matters). Fill if
print px <= bid (the book crossed our level — queue-position optimism
stated). Fill price = our bid. Maker pays no taker fee. Per-token cooldown
60s, max 5 lots. Sprints only inside their window (no s0 lookahead —
harness rule, not the tape scorer's).

Grid (pre-declared, not tuned after): m in {2c, 4c, 7c} x R in {1s, 4s}.
Readouts: EV/fill (chain), hit, fills/day, fair-markout at +60s (adverse
selection: how far fair moves against us right after we're filled).
NOT pre-registered — Stage 1 of the maker pivot; a live paper maker arm
only if this survives its own optimism caveats."""
