- H3 (burst overflow): per-wallet trade cursor + paginated activity fetch
(up to 5×100, walks back to the last processed timestamp) — a gkmg-scale
clip burst can no longer scroll past a single newest-100 page. Cursor
only advances after a fetch; 600s overlap re-serves boundary rows into
the seen-tx dedupe. offset pagination verified against the data-api.
- clone-guard: Bearer auth (fine-grained PATs reject the 'token' scheme)
with unauthenticated fallback + 40-hex sanity on the answer — Fly's
shared egress IPs rate-limit the anonymous path.
- preflight_live.py rewritten for the unified SDK: deposit-wallet auth,
pUSD collateral, order-book reach, RTDS stream delivery, geo verdict.
- ledger-drift ALARM floor 1c → 5c (4dp fill rounding accumulates pennies
across 60+ copies; the check stays for real bugs — it caught $15.45 and
$7.24. The self-heal path keeps its own threshold.)

User call 2026-07-13 after a big 0.001 longshot was floor-blocked (the
same band class that blocked the 16x Hive copy at 0.05). Executor's
protected prices now round to 4dp and scale with the price — the old 2dp
rounding zeroed the bound on sub-penny books (BUY never bounds below the
quoted cross; SELL never above the quoted bid; verified at 0.001/0.002).

2026-07-12 phantom-cash incident (+$7.86 book-only, alarms caught it):
overlapping pendings on one token each read the same balance drop via
max(matched, diff) — one real 1.48-share sell booked 3×. No real money
moved wrongly (the CLOB rejects oversells); the book just self-inflated.
Fixes: (1) order's own size caps every adoption fill; (2) the balance
diff is consulted ONLY when the exchange no longer answers for the order
(a definitive killed/0 is final); (3) SELL adoptions cap at book
holdings; (4) ONE outstanding pending per token — engine buy/sell and
exit-retries refuse while the resolver owns a token. Regression suite:
the incident scenario books exactly the real fill; phantoms zero.
Surgery (machine stopped): cash → chain $11.206, the two poisoned bets
corrected from real chain fills (residual adjustment −$0.08), drift 0.
