Additive (non-breaking): decide(factors=None) keeps the V3a base-only path (existing
11 tests unchanged); decide(factors=SizingFactors(...)) produces BLUE-complete
conviction via VioletSizer (base_max=8 + dc/regime(ACB)/ob/esof, capped@9) with the
full factor breakdown on ShadowDecision (base_leverage/dc_lev_mult/regime_size_mult/
market_ob_mult/esof_size_mult, None on the base path). SizingFactors value object =
the live-plane inputs the launcher will source (V3.4b). 6 new tests incl. consistency

Logs the open question (noise/denominator artifact vs real depeg micro-edge

Soak surfaced USDCUSDT being shorted. BLUE has a hardcoded exclusion gate around
its (muted-IRP) picking: _STABLECOIN_SYMBOLS removed from prices_dict pre-select
(nautilus_event_trader.py:24/3906). Replicate exactly: VioletDecisionEngine skips
the same 10 symbols in observe() so IRP never sees them. Following BLUE in all

90s BTCUSDT-PERP capture on the prod host, public data, dummy creds
(factory demands key env vars even for the data client; public endpoints
ignore the header). NT internal dispatch p50 0.23ms / p99 3.3ms — inside
VIOLET reactor budgets; 77 ticks/s sustained, zero drops. Qualifications:
NT owns its (uvloop) event loop -> recommended separate feed process
bridging via Zinc/HZ; exchange->cb p50 135ms is network+NTP+throttle, a
relative baseline only; PRODGREEN-era launcher API calls no longer exist
in 1.219 (FUTURES->USDT_FUTURE) — pin version + API smoke on adoption.

exec_driver.py lifts PINK's TTL-resolution logic (_exec_after_submit /
_handle_expired_working, live-proven) into a standalone driver with
injected ports (router/submit/pump/slot_view/venue_flat/ref-price) and
replaces the 1s polling sweep with one DeadlineScheduler deadline per
working order. The driver is the TIMING authority (router clamps TTLs
>=0.5s — its internal deadline is vestigial here); the router stays the
POLICY authority. R1 preserved verbatim: exit TTL -> MARKET escalation on
the SAME trade_id; post-only reject -> schedule_in(0) through the one
shared resolution path; venue-truth requote gate fails safe.
scripted_venue.py subclasses MockVenueAdapter (zero shared edits) with
per-trade directives: IMMEDIATE_FILL / REST_THEN_FILL / REST_THEN_EXPIRE /
POST_ONLY_REJECT / CANCEL_REJECT / FILL_RACES_CANCEL; deferred fills
release through reconcile() (the production pump seam), never the 50ms
subscribe() poll.
17 new tests incl. full-kernel CANCEL->venue mapping, fill-races-cancel,
bounded retry chains, on_fill deadline cancellation, fail-safe probe.
Router 77 green untouched; shared files clean.

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

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

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

ch_writer: _writer_violet (db=dolphin_violet) + ch_put_violet, the existing

_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

PinkAssetPicker/PinkAlphaSizer (BLUE-parity IRP picker + sizer, 2026-06-10)
plus the 2026-06-11 fix: price_of falls back to the dehyphenated symbol —
reconcile/fill paths write venue format (FET-USDT) into the slot while the
scan universe keys are Binance-style (FETUSDT); without the fallback an
adopted slot had no price and TP/SL/MAX_HOLD never evaluated (the unmanaged

TP_FLOOR (LINK 5e05eeeb, -$1,248.71): once the BASE 0.20% TP is crossed,

TP-widening (which is logged per decision now: dynamic_tp_pct,
tp_mod_factor, cascade_count, ob_regime_signal, tp_floor_armed on
v7_decision_events). Class default OFF (champion parity); live ON via
DOLPHIN_TP_FLOOR.
Malformed-OPEN Option A (causal fix): POSITION_DUST_NOTIONAL_USD shared by
the full-close decision and the single _ps_write_open lifecycle gate (OPEN
rows can never round to zero size on disk); retract terminal leg writes its
trade_exit_legs + trade_reconstruction rows; restore reject-exhaustion halts
for unknown-corruption classes and flat-continues only for the documented
zero-size tombstone class; chain-token mismatch emits a CHAIN_TOKEN_MISMATCH
journal event; restored entry_bar preserves bars_held continuity (negative
entry_bar allowed, Int32) in both CH and HZ restore paths.
Tests: test_tp_floor.py 16/16 incl. LINK golden replay;

Review of PINK_ACCOUNTING_EXEC_FIX execution found the Phase 3.2 repair
path triply broken: (1) !closed guard blocked repair on terminal fills —
the common price-less case; (2) wrapper on_account_event was a raw FFI
passthrough so repairs never settled into published capital; (3) live
FILL_SETTLED carried no slot_id and realized_pnl=0 (pre-folded) — repair
was dead code. Fixes: repair allowed on closed slots (flag+dedup keep it
idempotent); wrapper settles the baseline diff on FILL_SETTLED-with-slot_id;
dedicated repair_realized_pnl field avoids double-folding the K-ledger;
_FakeKernelAccount fixture mirrors the Phase 1 anchor_to_exchange contract.

Two related accounting fixes:
1. _calibrate_fee_model startup guard: before calling calibrate_fee,
compute raw deviation from the published taker/maker rate (ignoring
any stale calibration_ratio). If >15%, skip and log WARNING rather
than letting a bad REST fill set calibration_ratio to ~0.8 and cause
ESTIMATED fees to understate actuals by 20% for the entire session.
2. fee_settled_events trade_id: BingX WS does not echo back our
clientOrderId in fill events (field "c" is empty). Was falling back
to BingX's internal orderId (p-e-mq5.../p-x-mq5...) which can't
be joined to trade_events. Now reads trade_id from kernel slot 0
(which retains the trade_id until the next ENTER) so
fee_settled_events.trade_id = BTCUSDT-T-N. Added venue_order_id
field to persist_fee_settled for bidirectional reconciliation.
128/128 tests green.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
trade_seq was missing from the kernel account snapshot dict, so the
intent engine always computed trade_id = "BTCUSDT-T-000000000001".
The Rust FSM SLOT_BUSY guard only fires on *different* trade_ids; with
the same ID it resets the slot and submits a new exchange order on each
ENTER signal tick (~86 duplicate orders observed in one session).
Fix:
- Add _slot_was_closed dict to ExecutionKernel; set False on ENTER
accepted (both sync/async), True on on_venue_event when slot.closed
- Increment account.snapshot.trade_seq on the IDLE→CLOSED transition
- Expose trade_seq in snapshot()["account"] so DecisionContext carries
the correct counter → intent engine generates unique IDs per trade

Adds dolphin-supervisord.service (installed + enabled) and dolphin_startup_check.sh:
- ExecStartPre waits for HZ (CRITICAL/blocks), CH+Prefect (WARN/degraded-ok)
- Logs to /tmp/dolphin_logs/startup.log + run_logs/dolphin_startup_<date>.log
- Writes machine-readable /tmp/dolphin_logs/startup_status.json on every start
- nautilus_trader remains autostart=false — BLUE must be started manually
SYSTEM BIBLE bumped to v7.1; §16.10 updated, §16.14 added.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Add §16.10 corrected daemon start sequence (supervisord NOT auto-started on boot),
§16.12 critical supervisord.conf rules (no /tmp paths, OBF starvation → BLUE freeze,
pre-restart position check), §16.13 OOM recovery runbook with exact commands.
Incident context (2026-06-08):
- Previous agent set nautilus_trader to /tmp/blue_runtime_mirror/ — broken after OOM reboot
- OBF died during BLUE run, degraded gate for 285+ bars, BLUE stuck in RETRACT on LTCUSDT
- Fix: revert supervisord.conf to /mnt canonical paths, restart supervisord
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
A previous agent changed nautilus_trader to run from /tmp/blue_runtime_mirror/prod/
and updated PYTHONPATH + DOLPHIN_LOCAL_RUNTIME_ROOT to match. /tmp/blue_runtime_mirror
no longer exists after the OOM reboot, so supervisord could not start BLUE.
Fix: restore canonical paths for nautilus_trader:
command: /mnt/dolphinng5_predict/prod/nautilus_event_trader.py
directory: /mnt/dolphinng5_predict/prod
PYTHONPATH: /mnt/dolphinng5_predict:/mnt/dolphinng5_predict/nautilus_dolphin:/mnt/dolphinng5_predict/prod
DOLPHIN_LOCAL_RUNTIME_ROOT: /mnt/dolphinng5_predict
Rule: NEVER point nautilus_trader at /tmp. /tmp dirs are volatile;
canonical trader binaries must always be referenced via /mnt paths.

Defect A (fee sign): bingx_user_stream._normalise_order flipped to
fee = -raw_fee so BingX negative-n costs arrive as positive kernel
costs. k_maker_rebates no longer accumulates phantom rebates.
Defect B (opening fee dropped): fill_qty now falls back to "z"
(cumFilledQty) when "l" (lastFilledQty) is zero/absent, so
apply_predicted_fill computes a non-zero opening-leg fee.
Architectural fix (WARN unfreezes): lib.rs reconcile() now unfreezes
capital_frozen on WARN as well as OK. WARN (0.01-20 USDT delta) is
normal in-flight settlement — only ERROR (≥20, unexplained) should
halt ENTERs. The old keep-state logic trapped the kernel permanently
frozen after the first trade's ENTER predicted-fee phase pushed delta
briefly into ERROR.
Acceptance criterion: |k_capital - bingx_balance| < 1 USDT, frozen=False
after every round-trip trade — verified numerically against T-1/T-2
ground truth from the CRITICAL doc.

Root cause: open_positions()/open_orders() called _backend_snapshot() ->
_call_backend() -> _run() -> pool.submit(asyncio.run, coro) which spawned a
temporary event loop in a worker thread. httpx AsyncClient created inside that
temp loop, loop closed immediately. All subsequent HTTP calls raised Event loop
is closed or asyncio.locks.Event bound to different loop. Crash triggered WS
stream reconnects; each reconnect re-ran reconcile with N>1 BingX positions and
orphaned all but the largest.
Fix: open_positions()/open_orders() now read backend._state (populated by
await backend.connect() in the main loop). Fallback to _backend_snapshot()
for callers without a connected backend.
Fixes test_bingx_bugs::TestConnectNoDoubleRefresh: connect() is now async.
New test_orphan_prevention.py: 23 tests covering all 5 orphan mechanisms:
A. open_positions/open_orders use backend._state, never hit thread pool
B. connect() awaitable, backend.connect() runs in main event loop
C. Reconcile guard: >1 position logs ERROR and takes only largest
D. clientOrderId p-action-base36-rand4 on every order
E. EXIT sizing capped to kernel slot_size
391 passed, 2 skipped, 0 failed across all 14 test files.

_reconcile_position_slot passed all N BingX positions (all slot_id=0) to
reconcile_from_slots; with N>1 the kernel silently took one and forgot the
rest. Now: sort by size desc, take only the largest, log ERROR naming every
ignored orphan symbol. Caller must flatten exchange to 0 before restarting.

- monitor_pink.py: wire real PinkClickHousePersistence so monitor roundtrips

Root cause 1 (http.py): duplicate signature= in POST body — canonical_query
included signature key after build_signed_params injected it, then body
appended &signature= again. Fix: exclude 'signature' from canonical.
Root cause 2 (bingx_direct + http.py): HTTP retry sent same MARKET order to
backup URL (bingx.pro), which hits the same VST account. Without clientOrderId,
each retry opened a new SHORT position; EXIT BUY 10 only closed one. Fix:
restore clientOrderId in hyphen format p-{e/x}-{base36_ts}-{rand4} (pure
alphanumeric rejected by VST; hyphen format accepted). Adds max_retries_override
+ urls_to_try to _request_json for non-idempotent override path.
Root cause 3 (flat_and_start_pink): k.venue.connect() ran backend.connect()
inside asyncio.run() in a thread-pool. httpx session created there references
a dead event loop; order POSTs raise RuntimeError("Event loop is closed").
Fix: await adapter.connect() directly from main event loop.
Also: enter_wall_ms + tight _is_our_position createTime filter to separate
PINK's position from concurrent strategies on shared VST account. 1.5s
settle sleep before flat check.
New test suite test_bingx_http_safety.py: 20 tests covering idempotency,
retry correctness, backup-URL dedup, event-loop hygiene, signing correctness.
Live result: ENTER 290ms, EXIT 260ms — both sub-second. Position flat.

Bug fixes:
1. bingx_venue.py: add cancel_async() — async cancel that awaits backend.cancel()
directly in the main event loop. The sync cancel() path goes through _run()
→ thread-pool → asyncio.run() in a new thread, but aiohttp is bound to the
main loop → deadlock. Identical root cause as the old sync submit() → fixed
via submit_async. Remove dead cancel_order branch (BingxDirectExecutionAdapter
has cancel, not cancel_order).
2. rust_backend.py: process_intent_async CANCEL path now uses cancel_async when
available (matching the submit_async pattern for ENTER/EXIT). Sync cancel()
fallback kept for MockVenueAdapter compat.
3. bingx_direct.py: guard S2 background refresh task per symbol. Old code discarded
the task reference; rapid submits piled up concurrent _refresh_state_background
calls all writing self._state in arbitrary completion order (stale last-writer-
wins). Now: skip creating a new task if one is already pending for the symbol;
store reference and clear via done-callback.
Test additions (test_bingx_bugs.py, 29 tests):
- cancel_async: awaitable, calls backend.cancel directly, maps all statuses
- process_intent_async CANCEL: dispatches cancel_async / falls back to sync
- S2 guard: task stored, no duplicates while pending, new task after done
- _events_from_submit with None snapshots: FILLED/NEW/REJECTED/PARTIAL/RATE_LIMITED
- _filled_size_from_snapshots(None, None): safe 0.0 return
- _events_from_cancel: before/after completely ignored
- connect(): no double refresh_state, no-op if backend has no connect
- submit() sync with None snapshots: FULL_FILL still emitted
- cancel() branch audit: uses cancel not cancel_order, raises for no-cancel backend
Fix: test_exchange_event_seam_parity.py TestMockSubscribe — replace deprecated
asyncio.get_event_loop().run_until_complete() with asyncio.run() (Python 3.12
raises RuntimeError when event loop is closed by earlier suite tests).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Fix 1: connect() — remove redundant _backend_snapshot(include_history=True).
backend.connect() already called refresh_state(); this was a second identical
network round-trip at startup (~400ms wasted).
Fix 2: cancel() — remove snapshot_before + snapshot_after. _events_from_cancel
never reads 'before' or 'after' — two gratuitous round-trips per cancel with
zero benefit.
Fix 3: submit() (sync/legacy path) — drop both _backend_snapshot calls, pass
None like submit_async already does. Receipt executedQty fields take precedence;
_filled_size_from_snapshots returning 0.0 is the correct safe fallback.
117/117 tests pass (2 pre-existing pytest-ordering failures in TestMockSubscribe
are unrelated — asyncio.get_event_loop() contamination from other suite files,
25/25 pass when the file runs alone).

S1 — Leverage cache (bingx_direct.py):
_ensure_leverage(): per-symbol asyncio.Lock + cached value check; skips ~350ms
POST when exchange already has the requested leverage. Saves ~350ms/trade.
Cache updated ONLY on success; failed POST leaves cache stale → correct retry.
Persist: JSON sidecar /tmp/.bingx_leverage_cache_{env}.json; survives restarts.
connect(): _verify_leverage_drift() detects when another process changed leverage
at the exchange and updates cache to exchange truth (logs WARNING on drift).
Multi-runner contract: leverage is account-level on BingX; documented that
concurrent runners with different leverage desires for same symbol conflict.
20 mock tests: same-lev skip, change-triggers-POST, failure-no-cache-update,
concurrent-same-symbol (lock prevents race), drift-detect, persist/restore,
multi-runner known-limitation documentation test.
S2 — Background state refresh (bingx_direct.py):
MARKET fills: asyncio.create_task(_refresh_state_background) — does not block
submit path. WS FILL_SETTLED + ACCOUNT_UPDATE deliver capital truth anyway.
LIMIT fills: synchronous refresh retained (include_history=False, not True) —
needed to detect resting order state for next pump cycle.
Saves ~600–900ms/trade on MARKET exits. ENTER similarly improved.
Gap 1 — VenueEvent friction fields (contracts.py):
Added: fee, fee_asset, fee_source, is_maker, exchange_ts, slippage_bps,
mark_at_submit — all with defaults so existing callers are unaffected.
Detailed inline docs for sign conventions and provenance codes.
Gap 2 — Fee estimation + WS_SETTLED provenance (bingx_direct.py, pink_clickhouse.py):
submit_intent: estimates fee from fill_price × fill_qty × taker/maker rate;
annotates ack_row with _fee_estimated, _fee_source, _is_maker_est.
persist_fee_settled(): new method writes fee_settled_events row when WS
ORDER_TRADE_UPDATE delivers actual commission ("n" field); fee_source="WS_SETTLED".
pink_direct._run_account_stream: calls persist_fee_settled on FILL_SETTLED.
Gap 3 — Slippage measurement (bingx_direct.py, bingx_venue.py, pink_clickhouse.py):
Captures mark_at_submit before the order POST; computes slippage_bps signed
by side: positive = adverse (taker overpaid / maker undersold), negative =
price improvement. Measured for BOTH taker and maker fills for symmetry.
Flows through VenueEvent → trade_events.slippage_bps + trade_exit_legs.slippage_bps.
S3 / SOR — Maker order placement: comprehensive TODO block in submit_intent with:
SHORT/LONG-aware price offset design, OBF integration requirements,
TODO_ADD_PARAMSET_VIBRISS for spread_bps threshold, intelligent timeout_s
calibration requirements, price-impact awareness gap, SOR abstraction CRITICAL TODO.
REST/WS split: documented why BingX (and all retail venues) separate these
and why a unified VenueAdapter protocol is the long-term solution.
151/151 existing tests green + 20 new leverage cache tests = 171 total.
