domain.py: refined scalar aliases (BarsHeld kills the bars_held=-106 UInt16 poison class by construction), DivergenceRow (DDL-shaped, frozen, extra=forbid), ExecDriverSettings (env boundary for the V2 driver; ttl override exists because the shared router clamps TTLs >= 0.5s), ExecGateReport schema, beartype 'typed' decorator with DOLPHIN_VIOLET_BEARTYPE=0 kill-switch. divergence.py: rows now parse through DivergenceRow before the sink — malformed rows die at the source with a rate-limited WARNING + counter, never at the head of the CH spool. Properties (hypothesis, derandomized): ExecutionRouter state machine (fill/retry mutual exclusion via pop-semantics, R1 exit escalation same trade_id, bounded retry chains, <=1 working ENTER), LatencyHistogram percentile laws (member-of-samples, monotone, extremes), DivergenceRow parse laws. 34 new tests; violet suite 64 green; router 77 green; zero shared-file edits.
