Root cause of zero live placements: the FIRST two qualifying signals
(Kruto 21:21, badaf Epic 21:53) each CRASHED the bot inside the
unguarded live order path (machine events: exit_code=1 seconds after
each signal; tick-size rejection the likely thrower — price was rounded
to 3dp on 1c-tick books). Fly restarted it and boot baseline marked the
fresh trades seen-without-copying: crash -> restart -> trade eaten,
twice. Fixes: _order never raises (failures return ok:False and feed
the new missed-row instrumentation); tick-size-aware pricing (cached
get_tick_size, buys ceil / sells floor, 0.01 fallback valid on every
book); size floored to 2dp; per-wallet poll guard (parity with the push
handler); baseline exempts trades younger than the stale window so a
restart can never eat a copyable trade again. host/order_probe.py =
controlled end-to-end placement proof (~$2 round trip).
