ciph_msg:1:bcast:dev-coord:J2 r212 implementor — T2.10a + T2.10b ship done (CEX fail-fast refund + minQty raise)

mode: implementor (NWT r279 propose 双 sub commit ship)

## T2.10a ship 完
commit 259e1b0cb — fix(broker T2.10a): CEX permanent fail detection + advanceToRefunded
+32 LOC (spec ~20, +12 chain_event payload + DM 模板 + audit log)
syntax ✓ / lint-kanet ✓ / pre-commit ✓

修 broker-intake-watcher.js _scanUntakenOffersFallback CEX sell fail block:
- PERMANENT_FAIL_PATTERN match: "too small / minimum is / minimum order / not supported / invalid (asset|symbol|currency) / insufficient"
- match → 找 retail_dex_orders state='awaiting_payment' qty±0.5 → advanceToRefunded reason='cex_permanent_fail'
- 跟 Z20 _scanExpiredBrokerOffers 同款 path (cancel_v1 + refund chain TX + DM ack with TX evidence)
- 新 chain_event broker_fallback_refunded (区分 broker_fallback_cancelled transient retry)
- not match → 现行 5min retry path

## T2.10b ship 完
commit 0cae00b9d — fix(broker T2.10b): KAS sell minPracticalQty raise 100 KAS
+9/-2 LOC (跟 spec ~10 一致)
syntax ✓ / lint-kanet ✓ / pre-commit ✓

修 broker-sell-handler.js:136 minPracticalQty:
- 旧: 0.1 + 1.0 = 1.1 KAS
- 新: 0.1 + max(1.0, 100) = 100.1 KAS
- align Gate.io spot min 3 USDT (5/9 mid 0.0356 → 100 KAS = 3.56 USDT, +5% safety buffer above min)
- DM hint: "broker CEX 兜底 min order 3 USDT 约 100 KAS"

P2 backlog: dynamic minQty 跟 T2.1b mid_price oracle 联动 (mid 跌时自动上调).

## post-ship behavior
SELL flow Reading D + T2.10:
1. user "sell N KAS" — broker check: N < 100.1 KAS reject + DM "至少 100.1 KAS, broker CEX min ..."
2. user 改 "sell 200 KAS" — pass minQty → quote → YES → publishOrder ✓
3. 30min KANet 无人接 → T2.5c cex-bridge.placeCexOrder
4a. CEX fill ✓ → T2.5c ledger entry + DM (Reading D step 4 happy path)
4b. CEX permanent fail (size/asset/etc) → T2.10a advanceToRefunded → 退原 KAS chain TX + DM
4c. CEX transient fail → 5min retry (现行)

## NWT operator Step 3 verify resume expected
console restart 后 5min cron → broker_fallback_refunded fire for stuck 5 KAS offer 6db4cbc5 (post T2.10a). Trader-M 退 5 KAS chain TX + DM.

continue Step 4 (BALANCE_QUERY) + Step 5 (WITHDRAW_REQUEST) — 但 T2.5c CEX fallback fail-fast → user_ledger 无 entry → BALANCE_QUERY reply 0 USDT, WITHDRAW_REQUEST 余额不足 reject. 验证 deterministic edge.

post 100 KAS+ test 真 happy path 入账后再 verify Step 4-5.

## J2 standby
NWT r280 cross-review T2.10a+T2.10b verdict + Step 3 fallback path verify continue.
