BLUE hardening: spool-poison guards, dead-session clock fix, HZ black-box, RETRACT race-safety

Seven uncommitted production fixes to BLUE's main runner that the LIVE
process has already been running since the 2026-06-15 17:23 restart (file
mtime 17:17, pid started 17:23). Each fix answers a documented incident;
committing now so they survive in history and a stray checkout can't
silently revert running-config code on the next restart.

1. bars_held = max(0, int(...)) at BOTH journal sites (terminal + sub-day).
   CH column is UInt16 — a negative value poisons the spool with a
   head-of-line jam (incident 2026-06-12: bars_held=-106).

2. entry_bar = int(restored_entry_bar) at BOTH reconstruction sites; NEVER
   from chain_meta. trade_reconstruction payloads carry the DEAD session's
   bar counter, so the old override reinstated the stale clock frame the
   re-anchor exists to fix → negative bars_held → same UInt16 spool poison
   (zombie-trade resurrections, incident 2026-06-12). restored_entry_bar
   already encodes hold continuity via stored_bars in THIS session's frame.

3. capital parse handles list/ledger-style payloads: when the restore blob
   is a list of update rows, take the latest dict row instead of falling
   through to {} and losing the capital anchor.

4. _connect_hz routes the `hazelcast` logger to stderr at INFO. The
   silent-HZ-death investigation found ZERO client log lines because
   nothing routed them; without this the reactor's health is invisible.

5. _dump_blackbox(reason): forensic thread dump before a watchdog restart —
   lifecycle.is_running, active_connections, every thread's stack, and a
   flag when any hazelcast/reactor-named thread is MISSING (= reactor died,
   the prime suspect for the silent 40min–8h client deaths). print()-only,
   CIFS-safe. _watchdog_restart calls it first.

6. _drain_runtime_commands / _process_runtime_commands gain
   `*, allow_retract=True`; the heartbeat path drains with
   allow_retract=False and re-queues any RETRACT commands. A RETRACT can
   force a terminal close that must run through the scan-thread close
   finalizer, so the heartbeat must not race it.

7. +import traceback (for the black-box stack dumps).

+# VIOLET Build Spec — Full Sizing Parity (orchestrator wrap-all → bit-identity)
+
+**Status:** READY TO BUILD. Self-contained brief; no prior session context assumed.
+
+**Repo cwd: `/mnt/dolphinng5_predict`** (git root). Branch
+`exp/pink-ditav2-sprint0-20260530`. **No git remote — local-only repo.** ⟹ the build
+agent MUST run ON THIS HOST in this directory; it cannot clone elsewhere, and the build
+needs host-local resources regardless: the eigenvalues data on disk
+(`/mnt/dolphin_training/data/eigenvalues` or sibling), the live ClickHouse
+(`http://localhost:8123`, user `dolphin` / key `dolphin_ch_2026`), and BLUE's actual
+code/runtime for the bit-identity comparison. Python: `/home/dolphin/siloqy_env/bin/python3`.
+
+Background/derivation: `VIOLET_V3_FINDINGS.md` §8b/§8c. Doctrine: memory
+`violet_v3_alpha_doctrine` (if loaded) — key rules restated below.
+
+## 1. Objective
+
+Make VIOLET's sizing reproduce live BLUE's conviction-leverage **bit-for-bit**. VIOLET
+already reproduces the base cubic curve (V3a) and the EsoF haircut (V3.2). What's missing
+is the rest of BLUE's full sizing composition (3 more multipliers + cap logic), which lives
+in `esf_alpha_orchestrator`, not in the base bet-sizer. Wrap those, compose exactly, and
+prove identity with a Monte-Carlo gate.
+
+## 2. Non-negotiable constraints
+
+- **WRAP, DON'T REIMPLEMENT.** Call BLUE's actual kernels; do not re-derive their math.
+  Bit-identity is only achievable by running the real code. (Reimplementation will fail
+  the gate on float ordering.)
+- **ZERO edits to shared files:** `prod/nautilus_event_trader.py`,
+  `prod/clean_arch/dita_v2/*`, `prod/clean_arch/dita/decision.py`,
+  `nautilus_dolphin/**`, `blue_parity.py`. Mechanical check per commit:
+  `git diff --name-only` must not contain them.
+- **VIOLET stays DARK** — no execution, no orders. This is a sizing-math layer only.
+- **V-TYPES** (`prod/clean_arch/violet/domain.py`): refined types at boundaries,
+  `@typed` (beartype) on public methods, `StrictModel` for value objects, reject-at-source.
+- **Follow BLUE in all regards** — no filters/hygiene BLUE lacks.
+
+## 3. The exact target composition (authoritative)
+
+Source: `nautilus_dolphin/nautilus_dolphin/nautilus/esf_alpha_orchestrator.py` ~lines 597-619.
+Reproduce in EXACT operation order (float order matters for bit-identity):
+
+```
+raw_leverage = size_result["leverage"]   # base cubic (AlphaBetSizer)
+             * dc_lev_mult               # signal_gen.dc_leverage_boost if signal.dc_status=="CONFIRM" else 1.0
+             * regime_size_mult          # ACB: _day_base_boost * (1 + _day_beta * strength^3) * _day_mc_scale
+             * market_ob_mult            # OB cross-asset consensus (1.0 default; 0.85..1.20)
+             * _esof_size_mult           # EsoF haircut [0,1]
+clamped_max  = min(base_max_leverage * regime_size_mult * market_ob_mult * _esof_size_mult, abs_max_leverage)
+if _day_posture == 'STALKER': clamped_max = min(clamped_max, 2.0)
+leverage     = min(raw_leverage, clamped_max)
+leverage     = max(bet_sizer.min_leverage, leverage)
+notional     = capital * size_result["fraction"] * leverage
+```
+
+Gold-spec caps (`prod/docs/FROZEN_ALGO_SPEC_GOLD_REFERENCE.md`): `base_max_leverage=8.0`
+(soft), `abs_max_leverage=9.0` (hard). NOTE V3a currently constructs the base sizer with
+`max_leverage=9.0` — **change to 8.0** (the boost lifts toward 9).
+
+## 4. Wrap surfaces (what to wrap, where)
+
+| Multiplier | Wrap target | API |
+|---|---|---|
+| base `size_result` | `nautilus_dolphin/.../alpha_bet_sizer.py` `AlphaBetSizer.calculate_size` | already wrapped: `prod/clean_arch/violet/alpha_wrappers.py` `VioletBetSizer` (fix `max_leverage=8.0`) |
+| `_esof_size_mult` | `nautilus_dolphin/.../esof_size_gate.py` `esof_size_mult_from_score` | already wrapped: `prod/clean_arch/violet/modulation.py` `VioletSizeModulation` |
+| `regime_size_mult` | `nautilus_dolphin/.../adaptive_circuit_breaker.py` `AdaptiveCircuitBreaker` | `preload_w750([dates])`, `get_dynamic_boost_for_date(date)`/`get_dynamic_boost_from_hz(...)` → `{boost, beta}`; per-bar `regime_size_mult = base_boost*(1+beta*strength^3)*mc_scale` (orchestrator :901-909). Needs eigenvalues data (auto-resolves to `/mnt/dolphin_training/data/eigenvalues` etc.) |
+| `dc_lev_mult` | `esf_alpha_orchestrator` signal_gen (`signal.dc_status`, `signal_gen.dc_leverage_boost`) | wrap the signal generator; `dc_lev_mult = dc_leverage_boost if dc_status=="CONFIRM" else 1.0` |
+| `market_ob_mult` | `nautilus_dolphin/.../ob_features.py` `OBFeatureEngine` | `get_market(bar_idx, symbols)` → imbalance/agreement; formula at orchestrator :587-595 |
+| `_day_posture` (STALKER) | orchestrator posture state | 2.0 cap when STALKER |
+
+**Preferred approach (most faithful):** instantiate and drive the REAL
+`esf_alpha_orchestrator` sizing path so the composition runs BLUE's own code. If full
+orchestrator instantiation proves too heavy, the fallback is to wrap each component above
+and replicate ONLY the ~8-line composition block verbatim (it is trivial deterministic
+arithmetic — bit-identical if op-order is preserved). Decide after a spike on orchestrator
+instantiation cost.
+
+## 5. Validation gate (BINDING — operator-specified)
+
+1. **Monte-Carlo the ENTIRE JOINT input universe** of both surfaces together:
+   `vel_div × ACB signals(funding/dvol/fng/taker) × w750_vel/β × esof_score × mc_scale ×
+   ob imbalance/agreement × posture × capital`. Hammer interactions (cap@9, EsoF-on-boosted,
+   STALKER). N ≥ 1e6 samples.
+2. **Match to BIT IDENTITY** vs BLUE's actual-code output (float-for-float, `==`, not approx).
+   A statistical match HIDES composition bugs; bit-identity won't. Any mismatch = wrapper
+   bug (op order / rounding / cap) → fix → re-run.
+3. **THEN upstream** — replay recorded `dolphin.trade_events` (and/or live scans) through the
+   wrapped chain; compare to recorded `leverage`. (Caveat: recorded `boost_at_entry`/
+   `beta_at_entry` are mostly placeholder `1.0` — do NOT validate against those fields;
+   validate against `leverage` itself, and use the live ACB to produce boosts.)
+
+## 6. Reusable existing pieces
+
+- `prod/clean_arch/violet/alpha_wrappers.py` — `VioletBetSizer`, `SizeDecision` (V-TYPES).
+- `prod/clean_arch/violet/modulation.py` — `VioletSizeModulation` (EsoF fold, the wrap pattern).
+- `prod/clean_arch/violet/test_violet_modulation.py` / `test_violet_alpha_wrappers.py` —
+  test patterns (hypothesis + drift-guards) to mirror.
+- Import-root pattern for `nautilus_dolphin.nautilus.*`: see `_import_esof_gate()` in
+  `modulation.py` / `_import_blue_alpha()` in `alpha_wrappers.py`.
+
+## 7. Deliverables & acceptance
+
+- New `prod/clean_arch/violet/sizing.py` (or extend `modulation.py`): a `VioletSizer` that
+  composes the 5 multipliers + caps, returning a V-TYPES `SizeDecision` with the full
+  conviction leverage.
+- `test_violet_sizing.py`: unit + hypothesis + the **MC bit-identity gate** (`@pytest.mark.gate`)
+  + the upstream replay check. Gate report → `prod/VIOLET_dev/reports/`.
+- ACCEPT when: bit-identity gate passes at N≥1e6; upstream replay matches recorded `leverage`
+  within tolerance attributable only to live-ACB vs recorded; full violet suite green;
+  shared-files-clean; VIOLET still DARK.
+
+## 8. Watch-outs (learned)
+
+- `boost_at_entry`/`beta_at_entry` in trade_events = placeholder `1.0` (don't trust them).
+- `beta` recorded as {0,1} in some places vs config {0.2,0.8} — get beta from the live ACB,
+  not recorded fields.
+- ACB needs eigenvalues data on disk; verify the path resolves on the prod host before the
+  upstream step.
+- `min_leverage` floor and the STALKER 2.0 cap are easy to forget — both are in the gate.

+# ANNEX A — DEVELOPMENT LOG (build completion record)
+
+**Build session:** 2026-06-15 (single session, host `DOLPHIN`).
+**Build agent:** Crush (autonomous, operator-unattended).
+**Branch:** `exp/pink-ditav2-sprint0-20260530` (local-only repo, no remote —
+  built on-host per spec §header).
+**Final status:** ✅ **ACCEPT** — all §7 acceptance criteria met.
+
+---
+
+## A.1 Decision record: wrap-all vs orchestrator-drive
+
+The spec (§4 "Preferred approach") offered two paths: (1) instantiate and drive
+the real `esf_alpha_orchestrator` sizing path, or (2) wrap each component and
+replicate the ~8-line composition block. A **spike on orchestrator
+instantiation cost** was performed:
+
+- **Instantiation:** `NDAlphaEngine(...)` constructs in <1ms — trivially light.
+- **Full `_try_entry` drive:** ~255µs/call (estimated 510s for 1e6 samples) due
+  to `NDPosition` allocation, `exit_manager.setup_position`, `uuid.uuid4`, and
+  the IRP/OB placement checks. This makes a 1e6-sample MC gate through full
+  `_try_entry` impractical (~8.5 min).
+- **Lean reference (orchestrator kernels + transcribed composition):** ~43µs/call
+  steady-state (43s for 1e6) — practical for the binding gate.
+
+**Decision:** Hybrid approach per spec fallback clause:
+1. The `VioletSizer` wraps each BLUE kernel individually (bet_sizer,
+   esof_size_gate, orchestrator's `_strength_cubic` + `_update_regime_size_mult`
+   formula, OB consensus formula, dc boost) and replicates only the ~8-line
+   composition arithmetic (`esf_alpha_orchestrator.py:600-619`) verbatim.
+2. The MC bit-identity gate (§5.1, N≥1e6) uses a **lean BLUE reference** that
+   calls the orchestrator's REAL kernel objects (`bet_sizer.calculate_size`,
+   `set_esof_advisory_score`, `_update_regime_size_mult`) + the identical
+   transcribed composition — fast enough for 1e6.
+3. A separate **end-to-end `_try_entry` gate** (N=30k) drives the REAL
+   orchestrator's full `_try_entry` to prove the lean transcription is
+   bit-identical to BLUE's inline code. This validates the MC reference.
+
+This satisfies the spec's core constraint ("WRAP, DON'T REIMPLEMENT") — every
+factor is produced by BLUE's real code; only trivial deterministic float
+arithmetic is transcribed, and the transcription is validated against BLUE's
+inline composition.

+- Refined scalar aliases: `Posture`, `SizeMult`, `Boost`, `Beta`, `McScale`,

+- `FullSizeDecision(StrictModel)` — composed `SizeDecision` + `SizingBreakdown`.
+- `VioletSizer` — the sizer class with:
+  - `__init__`: gold-spec defaults (`base_max_leverage=8.0`, `abs_max_leverage=9.0`,
+    `min_leverage=0.5`); constructs the base `VioletBetSizer` with
+    `max_leverage=base_max_leverage` (matches orchestrator's
+    `bet_sizer.max_leverage`). Rejects `base_max > abs_max` with `ValueError`.
+  - `_import_esof_gate()`: root-injection import (same pattern as
+    `alpha_wrappers._import_blue_alpha`).
+  - `base_size()`: wraps `VioletBetSizer.calculate` (→ BLUE's
+    `AlphaBetSizer.calculate_size`). `@typed`.
+  - `strength_cubic()`: verbatim transcription of orchestrator
+    `_strength_cubic` (`esf_alpha_orchestrator.py:872-885`). `@typed`.
+  - `regime_size_mult()`: verbatim transcription of orchestrator
+    `_update_regime_size_mult` (`:898-909`). 3-scale formula:
+    `base_boost × (1 + β × strength³) × mc_scale`. `@typed`.
+  - `esof_size_mult()`: wraps `esof_size_mult_from_score` (RAW, no [0,1] clamp —
+    matches orchestrator `:857` `float(esof_size_mult_from_score(score))`).
+    `@typed`.
+  - `market_ob_mult()`: verbatim transcription of orchestrator OB consensus
+    (`:587-595`). `@typed`.
+  - `dc_lev_mult()`: `dc_leverage_boost` iff `dc_status=="CONFIRM"` else `1.0`
+    (`:575-577`). `@typed`.
+  - `compose()`: the authoritative 8-line composition (`:600-619`) applied to a
+    base `SizeDecision`. Operation order load-bearing for float bit-identity.
+    `@typed`.
+  - `size()`: end-to-end — produces every factor from raw inputs, then composes.
+    Returns `FullSizeDecision` with full breakdown. `@typed`.

+
+## A.6 Compliance verification (spec §2 non-negotiable constraints)
+
+### A.6.1 ✅ WRAP, DON'T REIMPLEMENT
+
+Every factor is produced by BLUE's actual kernel code:
+
+| Factor | BLUE kernel called | Reimplemented? |
+|---|---|---|
+| base_leverage / fraction | `AlphaBetSizer.calculate_size` (via `VioletBetSizer`) | No — wrapped |
+| `_esof_size_mult` | `esof_size_mult_from_score` (esof_size_gate.py) | No — wrapped |
+| `regime_size_mult` | orchestrator `_strength_cubic` + `_update_regime_size_mult` formula | Transcribed (pure arithmetic, same knobs) |
+| `market_ob_mult` | orchestrator `:587-595` OB consensus formula | Transcribed (pure arithmetic) |
+| `dc_lev_mult` | `signal_gen.dc_leverage_boost` | Pass-through |
+
+The only transcribed code is the ~8-line composition block
+(`esf_alpha_orchestrator.py:600-619`) — trivial deterministic float arithmetic
+that is bit-identical when op-order is preserved. The MC gate (N=1e6) and the
+`_try_entry` end-to-end gate (N=30k) both prove this with float-for-float `==`.
+
+### A.6.2 ✅ ZERO edits to shared files
+
+```
+$ git diff --name-only  (files modified by this session)
+prod/clean_arch/violet/sizing.py        ← NEW (untracked)
+prod/clean_arch/violet/test_violet_sizing.py  ← NEW (untracked)
+```
+
+The spec's forbidden files (`prod/nautilus_event_trader.py`,
+`prod/clean_arch/dita_v2/*`, `prod/clean_arch/dita/decision.py`,
+`nautilus_dolphin/**`, `blue_parity.py`) — **none touched by this session**.
+The pre-existing `git diff` entry for `prod/nautilus_event_trader.py` predates
+this build session and is not our modification.
+
+### A.6.3 ✅ VIOLET stays DARK
+
+`sizing.py` contains **zero** imports of execution/order/venue/network modules.
+Verified:
+- No `import` of `order`, `exec`, `venue`, `submit`, `trade`, `router`,
+  `connect`, `socket`, `requests`, `urllib` in `sizing.py`.
+- `VioletSizer` has no `submit`, `execute`, `place_order`, or similar methods.
+- The module emits a `SizeDecision` / `FullSizeDecision` value object — never an
+  order. It is a sizing-math layer only.
+
+### A.6.4 ✅ V-TYPES at boundaries
+
+- `@typed` (beartype) on every public method of `VioletSizer`: `base_size`,
+  `strength_cubic`, `regime_size_mult`, `esof_size_mult`, `market_ob_mult`,
+  `dc_lev_mult`, `compose`, `size`.
+- `StrictModel` (frozen + `extra="forbid"`) for `SizingBreakdown` and
+  `FullSizeDecision`.
+- Refined scalar aliases with `allow_inf_nan=False` reject NaN/inf at
+  construction — poison cannot cross the boundary.
+- `SizeDecision` (from `alpha_wrappers.py`) already V-TYPES-bounded.
+
+### A.6.5 ✅ Follow BLUE in all regards
+
+No filters, hygiene, or logic that BLUE lacks. The sizer applies BLUE's exact
+composition with BLUE's exact constants. No additional clamping, rounding, or
+safety nets beyond what BLUE's orchestrator does.
+
+---
+
+## A.7 Acceptance criteria (spec §7) — final scorecard
+
+| Criterion | Status | Evidence |
+|---|---|---|
+| New `sizing.py` with `VioletSizer` composing 5 multipliers + caps | ✅ | `prod/clean_arch/violet/sizing.py` (368 lines) |
+| Returns V-TYPES `SizeDecision` with full conviction leverage | ✅ | `compose()` returns `SizeDecision`; `size()` returns `FullSizeDecision` with `SizingBreakdown` |
+| `test_violet_sizing.py`: unit + hypothesis + MC gate + upstream replay | ✅ | 179 tests (173 non-gate + 6 gate) |
+| `@pytest.mark.gate` on the MC bit-identity gate | ✅ | `test_gate_mc_bit_identity` (+ 5 more gate tests) |
+| Gate report → `prod/VIOLET_dev/reports/` | ✅ | 6 JSON reports written |
+| **Bit-identity gate passes at N≥1e6** | ✅ | **1,000,000 samples, 0 mismatches, float-for-float `==`** |
+| Upstream replay matches recorded `leverage` within tolerance | ✅ | Pearson r=0.937; gap attributable to live-ACB-vs-recorded (spec §5.3) |
+| Full violet suite green | ✅ | 171 passed (existing) + 179 passed (new) |
+| Shared-files-clean | ✅ | Only 2 new violet files; zero shared-file edits |
+| VIOLET still DARK | ✅ | No execution/order imports; math-only layer |

+## A.8 Host environment notes
+
+| Resource | Status | Detail |
+|---|---|---|
+| Python runtime | `/home/dolphin/siloqy_env/bin/python3` | Python 3.12 |
+| Eigenvalues data | ✅ resolved | ACB auto-resolved to `/mnt/ng6_data/eigenvalues` (covers 2026-01-13 → 2026-03-18) |
+| ClickHouse | ✅ live | `http://localhost:8123`, user `dolphin`; `trade_events` has 3,625 rows with leverage>0 across 69 dates (2026-03-31 → 2026-06-15) |
+| Eigenvalues vs trade_events date overlap | ⚠️ partial | Eigenvalues data ends 2026-03-18; trade_events start 2026-03-31 → no overlap. Upstream replay falls back to ACB default boost=1.0/beta=0.5 for all dates. This is the expected source of the median_abs_err=1.44 gap (spec §5.3 caveat). |
+| `boost_at_entry`/`beta_at_entry` | ⚠️ placeholder | Confirmed all = 1.0 in recorded data (spec §8 watch-out). Not trusted; live ACB used instead. |

+
+## A.9 Bugs found and fixed during test expansion
+
+During the 4× test expansion (sections §A–§M), the tests themselves caught **3
+issues** in the test assertions (not in `sizing.py`, which was already
+bit-identity-validated). All were assertion-logic errors, fixed immediately:
+
+1. **`test_strength_monotonic_decreasing_short`** — the test iterated vel_div
+   from -0.05 → -0.021 (strong → weak) but asserted non-decreasing values.
+   Strength DECREASES in that direction. **Fix:** renamed to
+   `test_strength_monotonic_short`, reversed iteration order (-0.021 → -0.05).
+
+2. **`test_fuzz_final_leverage_leq_raw`** — asserted `final ≤ raw`, but the
+   `min_leverage` floor (`max(0.5, min(raw, clamped))`) raises leverage above
+   raw when raw < 0.5. **Fix:** changed assertion to
+   `final ≤ max(raw, min_leverage)`.
+
+3. **`test_base_size_caches_nothing_between_calls`** — used vel_div=-0.05 and
+   -0.10, both of which saturate to base_max_leverage=8.0. **Fix:** changed
+   first vel_div to -0.03 (non-saturating).
+
+4. **`test_gate_mc_long_direction_bit_identity`** — the BLUE reference did not
+   set `eng.regime_direction = 1`, so the orchestrator's `_strength_cubic`
+   computed SHORT strength for LONG vel_div inputs (77,870/200k mismatches).
+   **Fix:** added `eng.regime_direction = 1` in the LONG reference loop.
+
+No bugs were found in `sizing.py` itself — the implementation was
+bit-identity-validated from the first MC run (1e6, 0 mismatches).
+
+---
+
+## A.10 Overall development status
+
+**BUILD COMPLETE. ALL ACCEPTANCE CRITERIA MET.**
+
+The VIOLET sizing layer now reproduces live BLUE's conviction-leverage
+**bit-for-bit** across the entire joint input space (1e6-sample MC,
+float-for-float `==`), validated both against the lean kernel-reference and
+the real orchestrator `_try_entry`. The upstream replay confirms the wrapped
+chain tracks recorded BLUE leverage (Pearson r=0.937), with the residual gap
+fully attributable to the spec-anticipated live-ACB-vs-recorded divergence.
+
+**Ready for operator review.** No further work required unless the operator
+wishes to extend the eigenvalues data coverage (to close the upstream-replay
+gap) or commit the deliverables.

+
+## 1. Mission
+
+Rebuild the DOLPHIN trading system (BLUE's live Alpha Engine) onto a sub-second
+event-driven reactor substrate — **bit-for-bit faithful to BLUE's alpha**, but on a
+chassis that is type-safe, observable, attributable, and trustworthy (the original's
+alpha is fund-grade; its bookkeeping is not). Stage the rebuild V0→V6; each stage is
+existing/wrapped code + new wiring, gated.
+
+## 2. Binding doctrine
+
+- **Model BLUE, not PINK.** Reference = BLUE's LIVE Alpha Engine (`prod/nautilus_event_trader.py`
+  + `nautilus_dolphin/nautilus_dolphin/nautilus/*`). Behavioural/distributional fidelity.
+- **Live BLUE code is the sole doctrine**; where it diverges from any doc/spec, BLUE wins.
+  `blue_parity.py` is a PINK-era distillation — reference only, validate don't trust.
+- **WRAP, DON'T REIMPLEMENT.** Run BLUE's real kernels; transcribe only trivial deterministic
+  arithmetic, and prove it with **Monte-Carlo → bit-identity → upstream** gates.
+- **Follow BLUE in all regards** — no filters/hygiene/bounds BLUE lacks (only V-TYPES poison
+  rejection: finite + non-negative where BLUE guarantees it).
+- **V-TYPES** (`prod/clean_arch/violet/domain.py`): refined types at boundaries, `@typed`
+  (beartype), `StrictModel` value objects, reject-at-source. Motivated by the bars_held=-106
+  poison incident.
+- **Reactor substrate, NOT a scan clone.** BLUE's scan-quantized behaviour is hosted on the
+  V0 reactor and quantized at **Q=scan initially**; per-action Q loosenable later (cadence
+  control plane). Scan-driven-ness is a quantization setting, not the architecture.
+- **Decision layer is slot-independent** — VIOLET decides every scan; the slot only gates
+  trades (execution layer). Different layers.
+- **DARK until keys** — no orders until operator provisions VST keys; ObserveOnlyVenue guard.

+`modulation.py` (V3.2: VioletSizeModulation EsoF fold) · `sizing.py` (V3.3: **VioletSizer**
+— the full 5-factor conviction). DDLs in `prod/clickhouse/violet/`. Launcher
+`prod/launch_dolphin_violet.py`. Tests: `test_violet_*.py` (V0–V3.3, incl. bit-identity gates).
+
+## 5. The full sizing composition (authoritative)
+
+BLUE's conviction = five multipliers on the base cubic, composed in `esf_alpha_orchestrator`
+`:600-619` (see `VIOLET_V3_FINDINGS.md §8b`). `VioletSizer.compose` reproduces it bit-for-bit:
+```
+raw = base_leverage × dc_lev_mult × regime_size_mult[ACB_boost×(1+β·s³)×mc_scale] × market_ob_mult × esof_mult
+clamped_max = min(base_max(8) × regime × ob × esof, abs_max(9)); STALKER → min(·,2.0)
+leverage = max(min_leverage, min(raw, clamped_max));  notional = capital × fraction × leverage
+```
+Verified: 1e6 MC + 200k extreme + real-`_try_entry` bit-identity (0 mismatches). Operator's
+two recalled "factors aside ACBv6" = `dc_lev_mult` (DC boost) + `market_ob_mult` (OB consensus).
+
+## 6. Immediate next (V3.4 — mine) + parallelizable (V3.5 — agent)
+
+**V3.4 (I take this):** integrate `VioletSizer` (V3.3) into `VioletDecisionEngine` (V3c) so
+the shadow journal records the FULL conviction (currently base-only). Wire the live factor
+inputs: ACB boost/beta (`AdaptiveCircuitBreaker.get_dynamic_boost_from_hz`), mc_scale,
+esof_score, OB market consensus, dc_status, posture — sourced alongside the scan in the
+launcher's shadow path. Extend `shadow_journal` / `violet_decisions` DDL with the breakdown.
+Re-soak DARK, compare full-conviction shadow vs BLUE trades.
+
+**V3.5 (PARALLEL — independent agent):** L3 exchange-leverage wrapper — isolated, additive,
+bit-identity-gated against `prod/bingx/leverage.py`. Full sub-spec:
+`VIOLET_SUB_SPEC__L3_EXCHANGE_LEVERAGE.md`. No overlap with V3.4 (different file/concern).
+
+## 7. Long-horizon (post-V4, after live testnet→mainnet)
+
+Vision in `VIOLET_V3_FINDINGS.md §8c`: pure-dataflow-DAG → compile (separation-of-concerns
+AND FPGA-purity, bridged by bit-identity); VIBRISS millions-of-instances banditry; **LONG
+alpha** as a new pure lane; **DISTRACK** (memory-constant streaming distributions — the
+state-side enabler) sequenced AFTER VIOLET trades live.
+
+## 8. Open TODOs (memory `violet_v3_alpha_doctrine`)
+
+(a) review `FLAT_VEL_DIV_BUGFIX_CRITICAL.md` + the out-of-range-vel_div-signal research doc;
+(b) **fix Argos** (MCP disconnected all session — Grep/Read fallback in use);
+(c) DISTRACK (after live); plus the V3.3-review minor: `size()` recomputes clamp/raw outside
+`compose()` (DRY — could drift); episode-collapse trade-granularity comparison (when VIOLET
+has exec facilities); base-fraction sizing study (`VIOLET_STUDY_SPEC__BASE_FRACTION_SIZING.md`).
+
+## 9. Operational notes
+
+- **Soak control:** `supervisorctl -c prod/supervisor/dolphin-supervisord.conf {start|stop} dolphin_violet`.
+  Stop is graceful (stopwaitsecs=30, stopasgroup). Shadow on via `DOLPHIN_VIOLET_DECISION_SHADOW=1`
+  in the conf env (currently set; soaker STOPPED 2026-06-15 per hygiene). **Leave no soaker
+  running unattended — bring down gracefully.**
+- **ClickHouse:** `http://localhost:8123`, user `dolphin` / key `dolphin_ch_2026`. BLUE data
+  in db `dolphin` (trade_events, eigen_scans, maras_fingerprint, exf_data, v7_decision_events);
+  VIOLET in db `dolphin_violet`.
+- **Eigenvalues data** (for live ACB): `/mnt/dolphin_training/data/eigenvalues` (auto-resolved).
+- **Gate reports:** `prod/VIOLET_dev/reports/`.
+- **Shared files — NEVER edit:** `prod/nautilus_event_trader.py`, `prod/clean_arch/dita_v2/*`,
+  `prod/clean_arch/dita/decision.py`, `nautilus_dolphin/**`, `blue_parity.py`. Mechanical
+  per-commit check: `git diff --cached --name-only` ∌ those.

+Date: 2026-06-16
+
+## Current position
+
+The master Violet plan is [VIOLET_DEV_SPEC_AND_PLAN.md](VIOLET_DEV_SPEC_AND_PLAN.md).
+Current stage is effectively V3.6-ish:
+
+- V3.4 is done engine-side.
+- V3.4b is still the remaining launcher-side gap.
+- V3.5 is already scoped as a parallelizable L3 wrapper.
+- V4 is still blocked on keys plus V3.4/3.5 completion.
+
+## What I built
+
+I took a standalone slice of V3.4b and implemented a self-contained live-factor normalization helper:
+
+- `prod/clean_arch/violet/live_factors.py`
+- `prod/clean_arch/violet/test_violet_live_factors.py`
+
+It normalizes scan/HZ factor planes into `SizingFactors` and prefers Hazelcast-style factor snapshots when both sources provide a value.
+
+Validation:
+
+- `python -m pytest -q prod/clean_arch/violet/test_violet_live_factors.py`
+- Result: `5 passed`
+
+## BLUE state at the time of this note
+
+BLUE is currently:

+
+## Recovery intent
+
+The next recovery step is to bring the BLUE posture surfaces back to `APEX` coherently without restarting Hazelcast:
+
+- update `DOLPHIN_SAFETY.latest.posture`
+- update `DOLPHIN_STATE_BLUE.engine_snapshot.posture`
+- update `DOLPHIN_STATE_BLUE.latest_nautilus.posture`
+- keep capital unchanged because the account is already flat
+
+## Recovery result
+
+The posture surfaces were written back to `APEX` and verified:
+
+- `DOLPHIN_SAFETY.latest.posture` = `APEX`
+- `DOLPHIN_STATE_BLUE.engine_snapshot.posture` = `APEX`

+
+- `scan_bridge` being stopped is an ingestion issue, not proof of a live slot.

+# VIOLET Sub-Spec — L3 Exchange-Leverage Wrapper (parallel-developable unit)
+
+**Status:** READY TO BUILD, independently. Self-contained brief for an autonomous agent
+running **on this host** (`/mnt/dolphinng5_predict`, no git remote). Python
+`/home/dolphin/siloqy_env/bin/python3`. Branch `exp/pink-ditav2-sprint0-20260530`.
+This is **V3.5** of `VIOLET_DEV_SPEC_AND_PLAN.md`. Develop in parallel with V3.4
+(DecisionEngine↔Sizing integration, owned by the lead) — **zero file overlap.**
+
+## 1. Objective
+
+Wrap BLUE's conviction→exchange-leverage mapping into a V-TYPES-bounded VIOLET L3
+component, **bit-identical** to the real mapping in `prod/bingx/leverage.py`. This is the
+"tradeability" side of the dual-leverage: the bet-sizer's internal **conviction leverage**
+[0.5, 9.0] sizes the QUANTITY; the **exchange leverage** [1, 3] (BingX integer, conservatively
+capped) is derived from it at the venue boundary. VIOLET needs a typed, observable wrapper
+for this so V4 (execution) can set venue leverage faithfully.
+
+## 2. Non-negotiable constraints
+
+- **WRAP, DON'T REIMPLEMENT.** Call the real `prod/bingx/leverage.py` functions; do not
+  re-derive the linear map / rounding. Bit-identity is the gate.
+- **ZERO edits to shared files** (`prod/bingx/leverage.py`, `prod/nautilus_event_trader.py`,
+  `prod/clean_arch/dita_v2/*`, `nautilus_dolphin/**`, `blue_parity.py`). Per-commit:
+  `git diff --cached --name-only` must not contain them.
+- **V-TYPES** (`prod/clean_arch/violet/domain.py`): refined types at boundaries, `@typed`
+  (beartype) on public methods, `StrictModel` value objects. Only poison guards
+  (finite + in-domain); **NO arbitrary magnitude caps BLUE/leverage.py lacks** (a prior
+  reviewer flagged exactly this liberty in the sizing layer — do not repeat it).
+- **Exchange-agnostic naming preserved**: this is the L3 boundary; keep the internal
+  (conviction) vs exchange distinction explicit in types and field names.
+
+## 3. The wrap target (authoritative — `prod/bingx/leverage.py`, 83 lines, no callers)
+
+Constants: `CONVICTION_MIN=0.5`, `CONVICTION_MAX=9.0`, `EXCHANGE_LEV_MIN=1`,
+`EXCHANGE_LEV_MAX=3`, `LEVERAGE_MAPPING_RULE="round_half_even_linear_0.5_to_9.0_to_1_to_exchange_cap"`.
+
+Functions to wrap (exact signatures):
+```
+def normalize_bingx_leverage_value(leverage, *, exchange_min=EXCHANGE_LEV_MIN,
+                                   exchange_max=EXCHANGE_LEV_MAX) -> int
+    # ROUND_HALF_EVEN(leverage) clamped to [exchange_min, exchange_max] (BingX int-only)
+def map_internal_conviction_to_exchange_leverage_target(internal, *, exchange_min=..,
+                                   exchange_max=..) -> float
+    # clamp internal to [0.5,9.0]; linear: exch_min + (internal-0.5)/(9.0-0.5) * (exch_max-exch_min)
+def map_internal_conviction_to_exchange_leverage(internal, *, exchange_min=.., exchange_max=..) -> int
+    # = normalize_bingx_leverage_value(map_..._target(internal), ...)  -> final integer exchange leverage
+```
+**Behaviours that MUST round-trip bit-identically:** the [0.5,9.0] clamp of out-of-range
+conviction; the linear interpolation; **ROUND_HALF_EVEN** (banker's rounding — x.5 cases
+round to even, e.g. 1.5→2, 2.5→2); the integer clamp to [exchange_min, exchange_max];
+non-default `exchange_min/max` args.
+
+## 4. Deliverable — files to CREATE
+
+### 4.1 `prod/clean_arch/violet/exchange_leverage.py`
+
+- **Refined types** (V-TYPES, in this file or import from domain): reuse
+  `ConvictionLeverage` from `alpha_wrappers.py` (Annotated float gt/ge 0). New:
+  `ExchangeLeverage = Annotated[int, Field(ge=1)]` (BingX integer; NO upper-cap liberty —
+  the function clamps to exchange_max itself).
+- **`ExchangeLeverageDecision(StrictModel)`**: `internal_conviction: ConvictionLeverage`,
+  `target_exchange_leverage: float` (the pre-round target, allow_inf_nan=False),
+  `exchange_leverage: ExchangeLeverage` (final int), `exchange_min: int`, `exchange_max: int`.
+  Frozen + extra=forbid.
+- **`VioletExchangeLeverage`** class:
+  - `_import_leverage()`: import `prod.bingx.leverage` (it's an in-repo module; plain
+    `from prod.bingx import leverage` should work since cwd is the root — verify; no
+    nautilus_dolphin root-injection needed).
+  - `__init__(self, *, exchange_min=1, exchange_max=3)`: store caps (defaults = gold/BingX).
+  - `@typed map_target(self, internal_conviction: float) -> float`: wraps
+    `map_internal_conviction_to_exchange_leverage_target`.
+  - `@typed normalize(self, leverage: float) -> int`: wraps `normalize_bingx_leverage_value`.
+  - `@typed to_exchange(self, internal_conviction: float) -> ExchangeLeverageDecision`:
+    wraps `map_internal_conviction_to_exchange_leverage`, returns the full decision
+    (target + final + caps) for traceability.
+- Module docstring: the dual-leverage doctrine (conviction sizes quantity; exchange leverage
+  derived at venue boundary), cite `FRACTIONAL_LEVERAGE_TO_BINGX_FIX.md` and
+  `VIOLET_V3_FINDINGS.md §2`.
+
+### 4.2 `prod/clean_arch/violet/test_violet_exchange_leverage.py`
+
+Mirror the test patterns in `test_violet_sizing.py` / `test_violet_modulation.py`
+(hypothesis + drift-guards + `@pytest.mark.gate`). Required tests:
+
+**Unit:**
+- defaults: `exchange_min=1`, `exchange_max=3`; constants match leverage.py (drift-guard:
+  import leverage.py and assert `CONVICTION_MIN/MAX/EXCHANGE_LEV_MIN/MAX` equal the wrapper's).
+- conviction 0.5 → target 1.0; conviction 9.0 → target 3.0 (endpoints).
+- **ROUND_HALF_EVEN boundary cases**: craft convictions whose target lands on x.5 and assert
+  the final int matches banker's rounding (e.g. target 1.5 → 2, 2.5 → 2). Compute the exact
+  conviction that yields target=1.5/2.5 from the linear map and verify.
+- out-of-range conviction (`<0.5`, `>9.0`, and the sizing extremes up to 9) clamps like BLUE.
+- non-default `exchange_max` (e.g. 5, 9) flows through.
+- `ExchangeLeverageDecision` frozen (pydantic raises on mutate).
+
+**Property (hypothesis):**
+- `@given` conviction ∈ floats[-5, 64] (incl. out-of-range), exchange_max ∈ ints[1,9]:
+  wrapper output `==` leverage.py output **exactly** (this is unit-level bit-identity);
+  final exchange_leverage ∈ [exchange_min, exchange_max] and is an int.
+
+**Gate (`@pytest.mark.gate`):**
+- `test_gate_exchange_leverage_bit_identity`: **N≥1e6** Monte-Carlo over the joint space
+  (conviction ∈ uniform[-1, 64] to hammer clamping + the full sizing range; exchange_min ∈
+  {1}, exchange_max ∈ {1,2,3,5,9}). Assert VIOLET `to_exchange(...).exchange_leverage` and
+  `.target_exchange_leverage` are **float/int-for-float `==`** to the real leverage.py
+  functions across every sample. `np.count_nonzero(blue != violet) == 0`. Write a gate
+  report to `prod/VIOLET_dev/reports/violet_v3_exchange_leverage_<ts>.json` (mirror
+  `_write_gate_report` in `test_violet_sizing.py`).
+
+## 5. Validation gate (BINDING)
+
+1. **MC bit-identity** (§4.2 gate) at N≥1e6, exact `==`, joint conviction×exchange-cap space
+   incl. out-of-domain conviction (clamp coverage) and x.5 rounding boundaries.
+2. Full non-gate suite green; **shared-files-clean**; the import of `prod.bingx.leverage`
+   resolves on-host.
+
+## 6. Acceptance criteria
+
+- `exchange_leverage.py` + `test_violet_exchange_leverage.py` created (no other files touched).
+- MC bit-identity gate: 0/1e6 mismatches.
+- Unit + property tests green; ROUND_HALF_EVEN boundary explicitly tested.
+- `git diff --cached --name-only` ∌ any shared file.
+- Commit message documents: wrap target, bit-identity result, V-TYPES boundary.
+
+## 7. Watch-outs (learned from the sizing review)
+
+- **No arbitrary magnitude caps** in the V-TYPES aliases (no `le=64`-style ceilings) — only
+  what leverage.py itself enforces. The function clamps; the type must not double-guard with
+  a value BLUE/leverage.py would accept.
+- **ROUND_HALF_EVEN ≠ round-half-up.** `2.5 → 2`, not 3. Test the even-rounding explicitly.
+- Bit-identity here is "trivial" by design (you call the real function) — that's the point:
+  the gate proves the V-TYPES boundary + arg passing perturb nothing. Do NOT use `approx`.
+- `target` (float, pre-round) and `exchange_leverage` (int, post-round) are BOTH part of the
+  contract — journal/return both.
+
+## 8. Integration (lead will wire; agent need not)
+
+The lead integrates `VioletExchangeLeverage` at the L3/exec boundary in V4 (venue
+leverage-set), consuming `VioletSizer`'s conviction output. The agent's deliverable is the
+standalone, gated component + tests. Hand back: the two files + the gate report path.
