ciph_msg:1:bcast:dev-coord:[J2 #732] Block A.3 Wave 3 SHIPPED — 3 production hardcode sweep, swap capability unblocked @NWT @Owner

commit: `72511ded5` (4 files, +32/-9 LOC)

## NWT r248 spec verbatim — Option C ack

Owner thesis 5/23: '换一个 broker 和 MarketMaker-A maker 可以吗? 这样才能看看系统真实迁移能力.'

## 3 production fixes

### A. broker-state-machine.js — checkBrokerEscrow dynamic broker addr

```js
// before: const TRADER_B_KAS_ADDR = 'kaspa:qrxw764...' (used 2x lines 302/313)
// after:  import { getBrokerRelay } + resolve broker.address at call time
```

Graceful: returns false if no broker configured (= swap mid-transit safe).

### B. cross-match-engine.js — dynamic broker org names

```js
// before: const BROKER_ORG_NAMES = ['Trader-A', 'Trader-B', 'Trader-M']
// after:  import { getBrokerOrgNames } new export in broker-config-resolver
//        SELECT name WHERE roles_json json_each value IN ('broker','marketmaker')
```

New helper `getBrokerOrgNames()` 真 source of truth (= follow roles_json updates).

### C. admin.js stress-test-fund — dynamic broker name display

```js
// before: source: { broker: 'Trader-B' } hardcoded
// after:  SELECT name FROM relay_nodes WHERE address = brokerWallet.address
```

## NOT swept (intentional preserve)

- `migrate.js`:3044/4387/4391 — one-time backfill scripts, not runtime
- `test-framework/cases/*.test.mjs` — test fixture data, swap test target post-sweep

## Swap capability 真 unblocked

Before: 3 production code paths depend on Trader-B identity strings.
After: all resolver-driven. SQL UPDATE Trader-B roles_json removing 'broker' →
  resolver auto-fallback Trader-A (= ORDER BY created_at ASC LIMIT 1).

真 NWT swap test propose (~$0 dry-run):
```
1. SQL UPDATE relay_nodes SET roles_json='["user"]' WHERE name='Trader-B'
2. curl /api/admin/overview → broker should resolve to Trader-A
3. fire BUY DM 到 Trader-A address → broker-v3 handleMessage fires for Trader-A
4. verify _ensureRelation chain_event + relation_states INSERT
5. SQL UPDATE marketmaker remove → MarketMaker-A 接管
6. revert all (= restore Trader-B roles)
```

真 Trader-A KAS pool empty → 不真 deliver, config swap dispatch verify 即可证明.

## framework system 12/12 PASS

block_b_broker_fees_invariant Playwright flake → re-run PASS.

## task #86 Block A.3 真 close (finally)

Wave 1+2 5/22 ship, Wave 3 5/23 ship 闭关. 真 broker / MarketMaker swap test ready.

## standby NWT N19.270 audit + swap test fire 钦定

真 J2 broker line code 全 ready for Owner swap test. ~$0 dry-run.

coord-ack: Block A.3 Wave 3 SHIPPED — 3 production hardcode dynamic resolver-driven (broker-state-machine + cross-match-engine + admin.js) + getBrokerOrgNames new helper + swap capability unblocked + ~$0 dry-run swap test ready
