+# UV execution priority ladder — HJ's A–G adapted to our subsystems
+
+**Status:** doctrine. Supersedes the ad-hoc P0–P4 mapping in
+`asex_kernel_executor.py:_intent_priority`.
+**Origin:** HJ's generalized ladder (2026-07-13), adapted to DOLPHIN/UV subsystems.
+**Occasion:** the 2026-07-13 orphan incident, which is a textbook violation of it.
+
+---
+
+## The law
+
+Work is ranked by **what is irrecoverable if it is late**. Truth outranks action;
+safety outranks profit; profit outranks permission; research outranks nothing.
+
+A tier may never be starved by a lower tier. A lower tier may never *destroy* a
+higher tier's work — which is precisely what happened on 2026-07-13, when tier-G
+telemetry annihilated a tier-B fill.
+
+---
+
+## The ladder, mapped to our subsystems
+
+### A — Exchange / session safety  *(nothing is true if the pipe is lying)*
+| HJ's item | Our subsystem | State |
+|---|---|---|
+| heartbeat | MHS (market-health sensors), HZ client death detector | **not ranked work** — lives outside the queue |
+| disconnect | `LiveEFeed` WS lifecycle, HZ client isolation doctrine | **not ranked** |
+| sequence gap | `EEvent.venue_seq`, scanner dedup ratchet | **not ranked** (ratchet bug bit us 2026-06-22) |
+| trading halted | — | **MISSING** |
+| stale price / book | `E-TRIPWIRE` (e_feed), staleness labels | logs only, **not ranked** |
+| kill switch | `rm /root/uv-wt/prime-live/UV_PROMOTED.arm` (two-man arm) | **P0 ✓** |
+
+**Gap:** only the kill switch is ranked. Every other A-item is a log line or a
+startup gate (`VenueReadiness`, M4), not pre-emptive ranked work. A feed that has
+silently died outranks every trade decision — today it outranks nothing.
+
+### B — Execution truth  *(you cannot manage what you do not know you hold)*
+| HJ's item | Our subsystem | State |
+|---|---|---|
+| fills / partial fills | `EEvent.FILL` → `EKBridge` → kernel | **P4 — LAST** |
+| cancels / rejects | venue events → FSM | P4 |
+| open order state | `bingx_venue.reconcile()` | kernel-out only (cannot discover) |
+| true position | `/user/positions`, `AccountProjection` | **no adopt path at all** |
+
+**THE INVERSION — the single most important finding.**
+`asex_kernel_executor.py:319` enqueues account events at **priority=4**, the lowest
+tier — *below ENTER (P3)*. Under queue pressure UV will open a new position **before**
+applying the fill that tells it what it already owns.
+
+Tonight is the proof, and it is exact: the venue filled 6 orders (tier-B truth), and a
+tier-G telemetry exception erased the record of every one of them. UV then believed it
+was flat while holding 6 live SHORTs. **No SL, TP, or ADVSL can save a position the
+kernel does not know exists** — which is why B ranks above C and D, not below them.
+
+**Required:** account/fill events re-rank to **tier B (immediately below A)**, with a
+bounded drain batch so B cannot starve C.
+
+### C — Price-triggered capital preservation
+| HJ's item | Our subsystem | State |
+|---|---|---|
+| hard SL | catastrophic floor 0.0120, scan tighten-only | **P1 ✓** |
+| max adverse excursion | ADVSL (5 gates, `ASL_PRESSURE_CONT_STRESS`) | **P1 ✓** |
+| liquidation distance | — | **MISSING** |
+| daily / session loss | — | **MISSING** |
+| symbol loss | — | **MISSING** |
+| account leverage | leverage read for `tp_curve` only | **not a trigger** |
+| reduce-only emergency exit | P0 catastrophic EXIT | ✓ (used tonight to flatten) |
+
+### D — Profit preservation
+| HJ's item | Our subsystem | State |
+|---|---|---|
+| TP | `tp_curve` (0.0020 base + cubic), OB ×1.40/×0.60/×0.75, TP_FLOOR ratchet | **P2 ✓** |
+| trailing stop | — | **MISSING** |
+| giveback stop | TP_FLOOR ratchet is a partial analogue | partial |
+| time stop | MAX_HOLD (250 base × regime) | **P2 ✓** |
+| reprice / cancel stale resting exit | PINK `ExecutionRouter` maker/taker | **not ranked** |
+
+### E — Existing-order maintenance
+| HJ's item | Our subsystem | State |
+|---|---|---|
+| prevent duplicate orders | `TpSlHandler.submit_decision()` reservation boundary | ✓ (not ranked) |
+| cancel bad quotes / amend exits | `ExecutionRouter` | **not ranked** |
+| prevent self-cross | — | **MISSING** |
+
+### F — Entry permission  *(the only tier allowed to be slow)*
+| HJ's item | Our subsystem | State |
+|---|---|---|
+| DOLPHIN regime | regime/posture feed | ✓ upstream of queue |
+| SHEKHINAH / HD prediction | EFSM overlay, HD/TSF | ✓ |
+| OBF imbalance | OBF mid-injection | **double-dead** (hook-10 orphaned; runner steps pre-hook prices) |
+| spread / depth / slippage | — | **MISSING as a gate** |
+| funding / external | `FUNDING_FEE` events | accounted, not gated |
+| time-slot weighting | — | MISSING |
+| risk budget | capital/leverage | partial |
+
+`ENTER` sits at **P3 ✓** — correctly below every exit. The *gates* themselves run in
+decision code upstream of the queue, which is fine: permission may be slow.
+
+### G — Persistence / research  *(outranks nothing; may never block anything)*
+| HJ's item | Our subsystem | State |
+|---|---|---|
+| replay log / CH spool | M6 journal lane (durable spool + batcher) | ✓ off-path |
+| dashboards / telemetry | `bingx_venue` telemetry lane | ✓ **off-path as of today** |
+| LMDB | — | n/a |
+| model updates | MALKHUT / research | off-path |
+
+**2026-07-13:** telemetry was inline on the exec path and able to raise. It is now a
+bounded non-blocking ring (`deque(maxlen=4096)`, drop-oldest, drops counted) drained by
+a daemon lane. Measured: 3.65 µs/call on the exec path against a plane that blocks for
+2 s per publish; inline that was a 2000 s stall.
+
+---
+
+## Standing rules that fall out of the ladder
+
+1. **Truth before action.** Tier B is applied before any tier C/D/F work is
+   *decided*. A decision taken on a stale book is not a decision, it is a guess.
+2. **Nothing below tier B may ever mutate or veto tier B.** Telemetry, journals and
+   dashboards observe; they do not get a vote on whether a fill happened.
+3. **Non-blocking below tier C.** Anything at D or lower that touches I/O does it via
+   a bounded ring with drop-oldest. Loss of research data beats backpressure on capital.
+4. **Every tier is either ranked work or an explicit, documented exemption.** "It's
+   handled somewhere upstream" is how heartbeat, halt, and stale-book ended up
+   ranking below a dashboard write.
