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.

launch_dolphin_violet.py: own namespaces hard-set (CH dolphin_violet, HZ
DOLPHIN_STATE_VIOLET/PNL, Zinc prefix violet, DOLPHIN-VIOLET-001); own
credentials (BINGX_VIOLET_API_KEY/SECRET) — DARK idle with periodic WARNING
until provisioned; CH preflight SELECT-probes the required tables and NEVER
creates (DDL-before-code); kernel snapshot path repointed away from PINK's
fixed /tmp/.pink_kernel_state.json; mainnet hard-disabled; observe loop
never calls runtime.step(). ObserveOnlyVenue: submit/cancel raise
ObserveOnlyViolation with full attribute delegation — the kernel's
venue-submit-failure rollback converts a refusal into a synthetic REJECT
(slot back to IDLE), proven against the real kernel. FeedDivergenceMonitor:
per-asset scan-vs-venue divergence rows (bookTicker WS via
prod/bingx/market_stream, REST fallback) with stale-mid suppression and
plane seq propagation — the FET 0.2176-vs-0.1878 detector; runs even DARK
(public data). Supervisord [program:dolphin_violet] autostart=false, no
keys in conf by design. Violet package: 42 tests green + V0 gate.

ch_writer: _writer_violet (db=dolphin_violet) + ch_put_violet, the existing
per-strategy singleton pattern. bingx/journal: explicit violet entries in
_STRATEGY_DB_MAP/_SINK_MAP/_SINK_NAME_MAP — closes the hazard where the
unknown-strategy fallback routes venue journals into BLUE's dolphin DB
(regression-pinned in the new test, which documents the footgun for any
future strategy color). test_violet_namespace_isolation: violet sink
targets dolphin_violet exclusively; journal resolves violet explicitly;
Zinc region names for prefix violet disjoint from pink; persistence wired
with the violet sink routes only to dolphin_violet; HZ map-name contract
pinned for the C4 launcher. Shared-lib regression: 57/57 across PINK
kernel/runtime + BLUE tp_floor/malformed-open + bingx http safety.
