Bolts SmartExecBridge into the flight's scan loop behind UV_SMART_EXEC (default off). Fully
lazy: flag off => smart_bridge is never imported and the naive maybe_promote runs unchanged
(verified: runner import does not load smart_bridge when the flag is unset). Flag on =>
entries rest as PostOnly GTX makers, exits stay MARKET, the 6s tick drives TTL-abandon.
Reuses bridge.gate (two-man rule) + bridge.stats. runner.py compiles; wire import-safe both
paths. This is the 'bolt to flight 5/6' — dormant until an operator flips the flag and restarts.

SmartExecBridge: a drop-in for PromotionBridge.try_promote that rests entries as PostOnly GTX
makers (via exec_unified.router policy) instead of always paying the taker cross. DORMANT —
selected only by UV_SMART_EXEC=1 (default off); nothing imports it yet, so the running flight
is untouched. T1 = smallest bug surface (spec §15):
- ENTER -> maker (ACQUIRE): PostOnly LIMIT @ touch; unfilled by next scan tick -> CANCEL/abandon
('a missed entry is free' §4-1). No chase, no cross, no requote race.
- EXIT -> MARKET unchanged (never strand; zero new exit risk in v1).
- the 6s scan tick IS the drive clock: sweep-stale-then-place each promote.
Reuses router.decide + friction side-lane (never blocks a promote); fail-soft (never raises
into the scan loop). 11 tests, 2 mutation litmus RED (entry-maker policy; stale-sweep).

Real colnames (timestamp/u_prefix_client_id, anomaly_events.ts), query/VST
errors FAIL never PASS (no green-by-error), openOrders wrapper unwrap,
check(d) CH_ALLOWLIST_DBS attribution (BLUE OBF writer no longer flagged).
Maiden live runs by Fable caught all 6; PASS8 fixed same-night.
Read-only auditor for arming-checklist §4 anomalies, the instrument for the
72h-clean finish-line clock. 5 checks against CH + VST (all read-only):
(a) venue order without matching BRIDGE exec_journal row
(b) exec_journal row without venue order
(c) venue order without 'u-' clientOrderId prefix
(d) CH write outside dolphin_uv.* in runner window
(e) tripwire_ok=false occurrences

SHA256-identical to source. Fable verification: 20/20 pass; mutation litmus
RED (inverting the check-(c) prefix guard fails 6 tests incl. PASS8's own
test_c_mutation_* guards — the doctrine's litmus baked into the suite);
read-only confirmed (no writes on any path).
