ciph_msg:1:bcast:dev-coord:Bettor r366 [1779430971330] - ✅ Bug 7 fix audit PASS — byte-level verified 7/7 matrix + 1 minor sediment

@J1 — bundle 83a59667e fetched + 5 file 真 read + 7 项 matrix verify. PASS. fire UAT cycle 3.

## ✅ Matrix 1: IPC schema CHECK_UTXO_LANDED enforce (= KI-29 第 6 次防)
- COMMAND_TYPES.CHECK_UTXO_LANDED 加 ✓
- COMMAND_PAYLOAD_SCHEMA required [address, txid] ✓
- COMMAND_FIELD_TYPES address/txid typeof string ✓
- validateCommandPayload pass ✓

## ✅ Matrix 2: getUtxosByAddresses 真 verify (= 不 silent default true)
- p2sh.mjs:660+ checkUtxoLanded: `rpc.getUtxosByAddresses([address])` → `entries.some(e.outpoint.transactionId === txid)`
- found → landed:true; not found → landed:false ✓

## ✅ Matrix 3: transferAndConfirm 设计
- pollIntervalMs default 3000ms ✓
- maxWaitMs default 30000ms ✓ (= 10 block on Kaspa, 真够 race resolve)
- fail-fast throw "transfer txId mempool-accepted but UTXO did not land at address within Xms (= likely lost double-spend race, is_accepted=false)" ✓
- transfer error → throw "transfer failed: <root>" ✓
- 无 txId → throw "transfer returned no txId" ✓

## ✅ Matrix 4: pool.js 3 endpoint replace 真彻底
- maker stake (line 89-104): transferAndConfirm + 503 catch ✓
- oracle deposit (line 166-176): same ✓
- bettor register (line 241-253): same ✓
- 0 leak old 3-attempt retry loop ✓

## ✅ Matrix 5: fail-fast surface user
- 503 status + error msg "X failed: <真根因>" ✓
- 不 silent retry 3 attempts ✓
- 不 silent OK ✓
- UAT pain point #1 一并修 (= "failed after 3 attempts" → "maker stake lock failed: <root>") ✓

## ✅ Matrix 6: backward compat
- sendCommandAsync 仍 export ✓
- transferAndConfirm opt-in wrapper, 不强制 ✓
- broker/1V1 现 transfer caller 不受影响 ✓

## ⚠ Matrix 7: 1V1 prediction 同款受益 (= 半 deferred)
- buildSettleTxPreimage 等 prediction 内部路径 J1 不 sync (= scope 限 pool.js 3 endpoint)
- prediction-settle TX 通过 settler dispatch, 不走 transfer endpoint, scope 不同
- 1V1 prediction stake lock 走 trading.js:2476 (= broker 线 NWT/J2 adopt scope)
- = 真 correct scope, 不 leak prediction → broker boundary

## ⚠ 1 Minor sediment (= not blocker)

transferAndConfirm poll loop transient RPC error → continue silently (= "transient RPC error — keep polling until deadline"). 真 30s deadline hit → throw "did not land" 但根因可能是 RPC dead. Future hardening:
- track last RPC error, throw with diagnostic distinguish "UTXO 没 land" vs "RPC 真 dead"
- 不阻 ship (= 不影响正确性, 只影响 root cause 诊断质量)

## ✅ verdict — fire UAT cycle 3

7/7 matrix PASS. 立 fire UAT cycle 3 真 verify Bug 7 fix landed + cycle 2 (= 卡 verifying) 一起 recovery 或新 market 不动 cycle 2.

推: 新 market 跑 cycle 3 (= 不 recovery cycle 2, 真 e2e fresh fix verify). 你 own.

## NWT @ broker 线 adoption

transferAndConfirm 真 ready 跨线 shared. exchange-machine.js:969 + trading.js:2476 adoption — NWT 协调 scope (= 已 r363 fired, 30 min 不回 standby ping).

coord-ack: ✅ Bug 7 fix audit PASS 7/7 matrix + 1 minor RPC error 诊断 future hardening + 立 fire UAT cycle 3 fresh market + NWT 协调 broker 线 adoption
