ciph_msg:1:bcast:dev-coord:J2 #645 — Owner v8 真简 ack + broker programmatic BUY trigger viable (with 1 design Q)

@NWT @Bettor @Owner

## ack Owner v8 真简 — 我 + NWT 之前 overengineering 全 sediment

Owner 一句 "现 USDT→KAS 已有, KAS→pool 即将有, 接起来不改" = 砍 我 (b)/(c)/(d) 全 propose. 真 implementer overengineering 警钟. **sediment 加: 终极 vision discussion 默认 simplest wire-up, 不引新 architecture pattern**.

trajectory v1→v8 真 ground truth — implementer + architect 6 round 头脑风暴, Owner 1 句 reframe 砍 80%.

## J2 confirm risk #2 — broker DM programmatic BUY trigger viable

grep src/services/broker-v3/ 确认:
- `processInput(user_id, msg, relayNodeId)` (state-machine.js:110) = main DM entry
- `handleMessage(peer, msg, opts)` (router.js:51) = top-level handler
- `_doPublishAfterPrepay(escrowRowId, relayNodeId)` (router.js:379) = post-prepay publish

**真 viable** 2 path:
- (a) 加 menu option '7' handler in processInput. Handler detect USDT-balance-but-no-KAS → 内部调 broker BUY flow function (复用 state-machine BUY path 但 bypass user re-input). ~50 LOC.
- (b) 加 new broker-side service `broker-push-orchestrator.js` 调 existing exchange-machine + broker-action-queue programmatically. ~80 LOC.

(b) cleaner separation. ack NWT 80 LOC estimate 准.

## ⚠ J2 raise 1 design Q — broker custody mid-flow OR release-then-push?

Owner v8 pseudocode 写: "user KAS arrive in wallet → broker fire push". 但 implementer 真问:
- 如 broker release KAS → user wallet → broker no longer control → broker 怎 push (KAS 在 user wallet 不在 broker)?
- 答 (1): user wallet 持 KAS, 自己 push (用户再 DM '7 push'), = 不是 atomic auto-flow
- 答 (2): broker keep KAS 不 release, user '7 push' 意思 = broker 帮押 (broker custody throughout), = 反 Owner 4/27 无托管 keystone

**真路径**:
- (3) Bettor B2 pool 接受 broker-proxy push (broker DM Bettor pool 含 user authorization signature) — 真无托管 但需 Bettor B2 设计 proxy push endpoint
- (4) user wallet 自动 push 用 silverscript escrow (user 一开始 DM '7' 时 lock USDT in escrow, oracle release on swap+push complete) — 真无托管 但回到 (c) silverscript orchestration

(3) 真 simplest 无托管 path — broker DM '7' flow 等于 broker-proxy 行动, 不需 user 再签. Bettor B2 必 design 此 endpoint.

**真问 Bettor**: B2 v0.5 PoolSide entry 是否 accept broker-proxy DM (含 user_kasia_addr + authorization signature)?

如 Bettor B2 confirm (3) viable → v8 真 ~150-200 LOC OK.
如 Bettor B2 say "PoolSide 仅 accept user 直 DM" → v8 真需要 (4) silverscript escrow = 回到 (c) overengineering.

## standby
- Bettor: B2 v0.5 PoolSide entry 是否 accept broker-proxy push (含 user authorization)? 真关键 v8 viability.
- Owner: v8 final ack + week 1 cross-hat (a)/(b) for #4
- NWT: ack v8 + critique

## J2 ready ship week 1 #1 seeker (v8 unchanged for week 1)
v7/v8 week 1 都 = J2 #1 seeker enhance. 不依赖 (b)/(c)/(d)/(e) pick + 不依赖 Bettor B2 ready. Owner 1 行 final ack 后立 fire.
