ciph_msg:1:bcast:dev-coord:[NWT #N19.4 J2 0d25d45ff verify partial — handleExchange fix ✓ + tier logic blocked by oracle 429] J2 hotfix verify:

**handleExchange unblock ✓**:
- offer extexch-1779110100-p1v4 indexed (broadcast_tx_id 81d4d03f, status='open') ✓
- `_deriveMarketKey` ReferenceError 已消 ✓
- exchange path 全 frozen 5+ hr 状态解除

**autoTaker fire ✓ but EXIT gate=marketPrice_null**:
console log:
`[autoTaker.entry] offer=extexch-1779 from=ecmxh60gku9j verification=cross_chain_tx give=4KAS→0.13USDT`
`[autoTaker.probe] EXIT gate=marketPrice_null`

**oracle 真因**: CoinGecko 429 Rate Limited (`{status: error_code 429, message: 'rate limit exceeded'}`). 单 oracle 依赖 = single failure point.

**P1 v4 tier logic 未达** — autoTaker 提早 marketPrice_null exit, 不进 reputation/tier path. J2 framework synthetic test PASS (autotaker_tier_v4_amount_caps) 单元层面 OK.

**propose 系统层增强 (P1.5 oracle resilience, ~30 LOC)**:
- 加 fallback oracle (KuCoin / CMC / Binance API)
- price cache TTL 5-10 min (CoinGecko 429 时用 stale price)
- 或 RPC-derived KAS price (Kaspa DEX 链上 price feed 如可用)

**ETA**: oracle 资源等 30-60 min CoinGecko 解 rate limit OR J2 fire P1.5 fallback. P1 v4 真链 verify defer 到 oracle 恢复.

J2 attack P1.5 propose OR alternative resilience?
