Launcher shadow path now keeps the persistent state BLUE keeps across scans (faithful, not
per-scan single-shot): ONE OBFeatureEngine wired lazily on first assets and kept for the
service lifetime, reading BLUE's EXTANT published OBF feed via HZOBProvider (read-only HZ
entry-listener cache — NO new OB storage; provider is the swap seam for a future direct
BingX/3rd-party OB stream); per-scan ob_bar_idx into step_live/get_market; and prior_boost_beta
carried across scans (stale exf keeps the prior). shadow_decision_step threads ob_engine +
bar_idx + prior into source_live_blue_sizing_factors; build_shadow_live_source seeds the state
+ a default ob_engine_factory (injectable for tests).
TODO_HZBRIDGE markers added at all 3 VIOLET->Hazelcast touch points: per operator the upcoming
dolphinng5_predict/hzbridge must become the sanctioned HZ connection (silent client-death /
lockup / dropout mitigation) — refactor ASAP once it ships.
Doc VIOLET_OB_FEED_AND_AGENT_COORDINATION.md: OB-feed sourcing doctrine, HZ-bridge TODO, and
the multi-agent worktree + doctrine/release/status scheme (prompted by the shared-index
incidents where agents' staged files cross-contaminate commits).
6 launcher tests (+wired-once/bar_idx-increments, +prior-carries). violet-only; partial commit
(only my 4 paths) to avoid sweeping a concurrent agent's staged files.

Per operator: VIOLET must keep a "prior" on stale ExF rather than collapse to neutral, and
the ACB's role must be commented-in + logged.
- KEEP-PRIOR on stale/missing exf: BLUE keeps _day_base_boost/_day_beta on the stale branch
(update_acb_boost isn't called). _source_boost_beta now takes `prior` (boost,beta) and
returns it on ValueError / no-exf, seeded by the first successful compute. Threaded as
`prior_boost_beta` through source_live_blue_sizing_factors (caller persists last good).
- LOGGING: violet.live_blue_source logger emits live boost/beta + the full sourced plane.
- SEMANTICS: documents the ACB in effect (inverse v6) and CONFIRMS ACB IS in the sizing layer
via _day_base_boost/_day_beta → _update_regime_size_mult (esf_alpha_orchestrator.py:771-772,
898-909). OB Sub-4 beta modulation dormant in live — per operator found NON-PERFORMANT and
deliberately bypassed; TODO_SOMEDAY in-code to find documentary confirmation.

Operator directive: VIOLET must do IDENTICALLY what BLUE does for the three parity
flags — approximation cannot guarantee bit-for-bit functioning. Reworked
live_blue_source.py to call BLUE's OWN code paths, not reconstruct/substitute them.
boost/beta — was reading the published DOLPHIN_FEATURES.acb_boost scalar
(acb_processor_service's daily value). BLUE's trader does NOT use that for sizing; it
recomputes live via acb.get_dynamic_boost_from_hz(exf_latest, w750_velocity, direction)
with a bare AdaptiveCircuitBreaker() and NO ob_engine (nautilus_event_trader.py
on_exf_update:4769 / rollover prewarm:2710). New _source_boost_beta replicates that call
exactly (reads exf_latest + latest_eigen_scan.w750_velocity; 0.0→None like BLUE; on stale
exf ValueError → neutral, mirroring BLUE's "ACB Stale Data Fallback"). The published
acb_boost is never read. Test pins bit-identity against the real ACB.
signal-gen (dc_status) — was AlphaSignalGenerator() bare defaults; coincidentally equal to
BLUE today, but BLUE builds it from ENGINE_KWARGS (trader:128-133, threaded at
esf_alpha_orchestrator.py:180-191), so a champion retune would silently diverge. Now
constructed with BLUE_SIGNAL_GEN_KWARGS (vel_div_* imported from the kernel constants).
Test parses ENGINE_KWARGS from the trader source and asserts each param matches — drift
becomes a red test, not a silent miss.
OB — was a reinvented HazelcastOBProvider reading asset_*_ob with custom parsing. Now uses
BLUE's OWN HZOBProvider + OBFeatureEngine, wired exactly as _wire_obf
(nautilus_event_trader.py:4967-4980): step_live(assets, bar_idx) then get_market. Engine
is injectable + persistent so OB accumulation matches BLUE across scans (caller owns it).
Deleted: HazelcastOBProvider, _extract_acb, the status-label mc path. mc_scale fix
(begin_day cat/env thresholds) retained. Module docstring + structural-divergence doc
updated: all three flags FIXED; only _derive_mc_scale remains hand-replicated (pinned by
formula test). OPEN follow-up: launcher shadow_decision_step should pass a persistent
ob_engine + bar_idx for cross-scan OB history.
34 tests (33 + live-HZ smoke deselected): boost/beta-vs-ACB bit-identity (incl. w750=0→None,
no-exf, stale ValueError, ignores acb_boost), signal-gen ENGINE_KWARGS pin (parametrized),
OB wiring (step_live call, HZ coords, neutral paths), mc_scale formula, sequence dc/selector
parity, anomaly handling. violet-only; no shared-file edits.

REVIEW of the V3.4c/d/e work (other agents) for BLUE-algo compliance found one
real bug and one architectural concern.
BUG FIXED — mc_scale derivation (live_blue_source.py):
The adapter mapped `mc_forewarner_latest.status == "ORANGE"` → 0.5. But BLUE's sizing
mc_scale is NOT the MC service's `status` label (that label, from mc_forewarner_flow.py,
uses GREEN<0.10/ORANGE<0.30/RED — observability only). The live trader re-derives the
haircut in begin_day (esf_alpha_orchestrator.py:956-962) from the SAME published fields
`catastrophic_prob` + `envelope_score` with DIFFERENT thresholds:
mc_red = cat>0.25 or env<-1.0
mc_orange = (not mc_red) and (env<0 or cat>0.10)
mc_scale = 0.5 if mc_orange else 1.0
The two disagree (e.g. cat=0.05/env=-0.5 → label GREEN→1.0 but BLUE orange→0.5;
cat=0.28 → label ORANGE→0.5 but BLUE red→1.0). Rewrote `_derive_mc_scale` to mirror
begin_day exactly on the source fields. Per operator: there is genuine ambiguity over
which surface is "nominal" — we go with the SOURCE FIELDS + begin_day formula (the path
that actually drives BLUE's sizing); the ambiguity + decision are noted in the docstring.
TESTS — the old fixtures were complicit: they fed `{"status":"ORANGE"}`, a payload shape
BLUE never emits, so they "passed" against fiction. Replaced with BLUE's real payload
(`catastrophic_prob`/`envelope_score`) and added a parametrized formula test covering the
exact divergence cases the status-based code got wrong, plus missing/garbage-field neutral.
15 passed (live-HZ smoke deselected).
ARCHITECTURAL DEBT documented — VIOLET_BLUE_PARITY_STRUCTURAL_DIVERGENCE.md:
VIOLET imitates BLUE's computations in a DIFFERENT module/scope structure. Kernels are
WRAPPED (safe), but orchestration arithmetic (compose/regime/ob/strength/mc_scale) is
HAND-REPLICATED out of the monolithic NDAlphaEngine — making orderly, verifiable BLUE↔VIOLET
parity comparison and refactoring hard. Doc inventories every re-derivation with BLUE's
file:line authority, the drift risk, and mitigations (parity-pin tests; single canonical
surface per ambiguous factor; eventual DITAv2 Rust-backplane convergence). Pointer added to
live_blue_source.py's module docstring.
Also reviewed (no change needed): launcher launch_dolphin_violet.py is DARK-safe
(ObserveOnlyVenue + shadow gated default-OFF, no order path); shadow_live_factors.py glue
is correct; trade_slot_compare.py reimplements no BLUE algo. fb34431's launcher tests —
which the authoring agent never ran on the slow mount — pass (14 green).
