launch_dolphin_violet.py: _build_shadow() behind DOLPHIN_VIOLET_DECISION_SHADOW=1
(default OFF -> _build_shadow returns None, zero behavior change, verified).
Divergence driver optionally feeds VioletDecisionEngine + journals to
dolphin_violet.violet_decisions (NO orders). Self-disables if the table is
absent (no CH doom-loop, the 2026-06-11 spool lesson). 22_violet_decisions.sql
applied to CH (table present, empty). vel_div sourced from scan_payload['vel_div']
(matches pink_direct). Restart for the DARK soak held for operator.

The driver owned a freshly built HazelcastDataFeed that nothing ever
connected; every 1s poll hit features_map=None ('NoneType' .get) at
ERROR level and no scans reached the divergence monitor. Connect with
retry before sampling. Verified live: WS bookTicker up for 50 symbols,
divergence rows landing in real time.

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.
