ciph_msg:1:bcast:dev-coord:[J2 #340] Bug A 真因 dig + Bug A/B SHIP (commit 5cbd219b4) — UTXO race RCA = markUtxoSpent silent skip since 4/11 + preview报价 + 求 NWT review + J1 advisory Console restart

per Owner 5/14 严训 + NWT 2d7b88e8 alignment (J2 dig (i)(iv), NWT dig (ii)(iii)(v)).

mode: implementor (dig done + ship done)
acknowledged invariants: I-1, I-2, I-3, I-4
ships invariants: BSC menu DM reply 真上链 (Layer A markUtxoSpent 修 + Layer B reply retry handler) + preview 真报价
breaks invariants: NONE
coord-ack: 2d7b88e8 (NWT 2d7b88e8 alignment J2 ship Bug A+B + Tier 4 测试 plan)

## 1. Bug A 真因 — 比 NWT 假设更深 (silent skip since 4/11)

NWT 2d7b88e8 假设: "broker-v3 publish via /api/exchange/publish endpoint, reply via send_command, 不同 caller → broadcast 路径可能没 mark".

J2 dig (i)+(iv) 实证 (kasia-relay/src/lib/transaction.mjs:52 + console.log 实证):

**真因**: markUtxoSpent 旧 key probe `entry.entry?.transactionId || entry.transactionId` **不 match kaspa-wasm IUtxoEntry shape** (real path `entry.outpoint.transactionId` per kaspa-wasm v1.1.0 typed.ts L900-913 IUtxoEntry interface).

每 entry probe → undefined → key = ':0' → 安全 guard `if (key === ':0') return;` **silent skip** → `_pendingSpentUtxos` 永远空 → `filterPendingUtxos` 不 filter → publish broadcast + reply DM 3 ms apart pick 同 UTXO → RPC reject.

**markUtxoSpent 自 678a35b0f (4/11) 以来 silent 失效 33 天**. Phase D J1-D-4 (19bc9c09b) 的 explicit `markUtxoSpentByOutpoint` 从 error msg 提取 outpoint — 只 patch send_broadcast 路径 (relay.mjs:428), reply 路径 (rpc-listener.mjs:996) 没此 handler → Bug A surface.

console.log 实证 trace (Owner 5/14 08:51 实测):
```
01:50:43.344 [rpc] AI → ✓ 挂单已上链.
01:50:43.347 [rpc] Reply send failed: ... output (481658e5..., 0) already spent by
                   transaction 16c172301b... in the mempool
```

3 ms delta = publish broadcast TX 16c172... 真消耗 UTXO 481658e5:0, reply DM TX e4e4dd45... 同时 select 同 UTXO → 撞.

## 2. fix ship (commit 5cbd219b4, 4 files, 131 insertions / 12 deletions)

### Layer A — transaction.mjs (真 root cause fix)
- 加 `_outpointOf(entry)` 优先 entry.outpoint (kaspa-wasm UtxoEntry/UtxoEntryReference 都暴露 top-level outpoint)
- 加 `_utxoKey(entry)` backward-compat: outpoint → entry.entry.outpoint → flat (`entry.transactionId`)
- markUtxoSpent + filterPendingUtxos 改用 _utxoKey
- 不动 kasToSompi (J1 0ac4a571 Bug-Z23 保留)

### Layer B — rpc-listener.mjs replyToMessage (belt-and-suspenders)
- 加 mempool reject branch (mirror relay.mjs:428 send_broadcast Phase D J1-D-4)
- 识别 `already spent ... in the mempool` → markUtxoSpentByOutpoint + 2/4/6s backoff retry
- 不动 T-J2-2026-05-12 RPC state observability

### Bug B — state-machine.js _previewText (Owner 5/14 严训 §2 盲下单 fix)
- async + 调 exchange-client.getKasPrice (live oracle, 跟 router.js _doPublish 同 source)
- 加 KAS 中间价 + 总额 USDT/USDC line (base USDC 其余 USDT)
- oracle down → fallback 0.04 + warning
- _handleTradeFlow + processInput dispatch 改 async/await

### regression test (PASS)
- kasia-console/test-framework/cases/broker/bug_a_b_5_14_regression.test.mjs (6/6 PASS, 51ms)
- broker_v3_menu_6_chain.test.mjs 仍 4/4 PASS (no break)

## 3. NWT review 求 audit 第 0 步 + diff + 真因 cross-verify

NWT 5+ 步 audit:
- 第 0 步: grep 历史 fix — 4/11 678a35b0f + 4/28 19bc9c09b Phase D 看是否 sediment 漏 shape 问题
- diff 5cbd219b4 — 4 file 131 insertion
- 真因 cross-verify — kasia-wasm/kaspa.d.ts L900-913 IUtxoEntry shape vs L52 markUtxoSpent old probe
- exchange domain Phase 2 β + Phase B P0+P1 不退 (regression PASS proof)
- Tier 4 BSC C1 ship 后启

ETA NWT verdict ~15 min, 后 Tier 4 启.

## 4. ⚠ J1 advisory — Console restart needed for fix takes effect

state-machine.js 在 Console process import graph. Console 不 restart fix 不 take effect.
Console restart = 全 relay restart (含 J1 Bettor host decider).

J1 #170 刚 ship Sub 9.12 (2db1b6907) post-restart real fill 实测中. 我**等 J1 ack** 再 restart, 避免撞 J1 production tick.

@J1 — Bettor Sub 9.12 post-restart real fill 实测 done 后告知, 我立即 Console restart 启 Tier 4. ETA window ~30 min OK?

## 5. Tier 4 C1 BSC BUY round-trip (J2 ship 后立即 run)

NWT 2d7b88e8 §3 Test C1 1-6 step 用 J2 relay (作为 NWT test actor surrogate) → Trader-B real DM → verify:
- C1.1 'menu' → 6 选项 reply
- C1.2 '1' BUY → chain menu 6 选项 reply
- C1.3 '1' BSC → "已选 BSC 数量?" reply
- C1.4 '10' qty → **带报价 preview** reply (Bug B fix verify)
- C1.5 'Yes' → "✓ 挂单已上链 offer_id xxx" reply (Bug A fix verify)
- C1.6 '5' MY_ORDERS → status readable reply

每 step record TX hash + reply 时间戳 + 数据库 state. 失败 = 真 trace 真因.

J2 + NWT 各自 run, 不互 sign verdict, Owner 抽测 break chain.

## 6. immediate next

J2: standby J1 ack restart window + NWT review verdict.
J1: Bettor Sub 9.12 real fill 实测 done 后 ack restart OK.
NWT: 5+ step audit + verdict 5cbd219b4.

per [[feedback_no_pass_after_consensus]] + [[feedback_broadcast_after_commit]] + Owner 5/14 严训 + [[feedback_user_facing_audit_tier_4_required]] (KI 第 11 次复刻 sediment 求 NWT 同 ack).
