ciph_msg:1:bcast:dev-coord:[J2 #707] Phase 2.2 SHIPPED — 17 scenario dryRun impl module + 真 invoke 17/17 PASS @NWT @Owner

commit: `6c9518f05` (2 files, +319/-18 LOC)

## 真 module split

1. **`stress-test-v2-scenarios.mjs`** (新 210 LOC):
   - `SCENARIO_IMPL = { A1..D5 }` async functions per scenario
   - returns `{ ok, broker, user/users, preconditions[], would_trigger[] }`
   - factory pattern: `makeSell(N)` + `makeBuy(N)` for size 1/25/100

2. **runner integration**:
   - import `SCENARIO_IMPL`
   - executeScenarioStub → impl + try/catch fallback
   - log detail (user/users/error) + step list

## 真 17 scenarios real plan dryRun

```
STRESS_TEST_SEED=42 node scripts/stress-test-v2-scenario-runner.mjs

17/17 scenarios planned (dryRun=true):
  A1 SELL 1 KAS  → stress-user-02 (6 steps)
  A2 SELL 25 KAS → stress-user-05 (6 steps, hedge trigger)
  A3 SELL 100 KAS → stress-user-08 (6 steps, multi-leg hedge)
  A4-A6 BUY 1/25/100 KAS → various
  B1 并发 3 user → user-04, 06, control-02
  B2 timeout, B3 cancel
  C1-C3 simplified Trader-B 兼 + MarketMaker-A template isolation
  D1-D5 production gap (multi-chain / auto-replenish / reputation / failover / stuck)
```

## sample A2 plan (= 真 deterministic per seed)

```
A2 SELL 25 KAS 中单 (hedge trigger)
  user: stress-user-05
  kas_amount: 25, estimated_usdt: 0.8575
  fee: 0.1250 KAS (= Block A.2 公式 25 × 0.5%)
  steps:
  1. user publish exchange_offer (give=25 KAS, want=0.8575 USDT BSC)
  2. broker autoTaker filter: discount check vs market price
  3. broker accept → matched → user sends KAS to broker Kaspa
  4. broker delivers USDT to user BSC wallet
  5. hedge (CEX KAS buy back, if size ≥ 25 KAS)
  6. chain_event broker_fee_collected
```

## Phase 2 进度

```
2.0 ✅ scenario runner skeleton + 17 case stub + RNG seed (134 LOC)
2.1 ✅ scheduler + dry-run + abort + pre-flight fold (+99 LOC)
2.2 ✅ 17 scenario dryRun impl module (+319 LOC, this commit)
2.3 待 — invariant test fold framework (~30 LOC)
```

Phase 2 总 ~552 LOC 真 ship (= NWT 550-650 estimate close).

## NEXT Phase 2.3 — invariant test fold (~30 LOC)

invariant test:
- 17 scenarios 真 return valid plan structure (ok + broker + would_trigger)
- chain_event would_trigger reference 真 match production event types (= autotake_skip, broker_fee_collected, hedge_placed, exchange_cancelled, broker_auto_replenish_v2)
- pre-flight 真 fail 时 abort 真 enforce

fire Phase 2.3 等 NWT N19.246 audit 2.2.

## Owner Phase 1B 真 1B 钦定 pending (~30 min)

NWT audit speed 真 fast (= 3 min cycle), Owner Phase 1B 钦定 真 unblock real-money fire → Phase 5 24h 跑.

coord-ack: Phase 2.2 SHIPPED — 17 scenario dryRun real impl + 真 invoke 17/17 PASS + Group A 6 + B 3 + C 3 + D 5 全 cover + Phase 2 总 ~552 LOC close to NWT estimate
