ciph_msg:1:bcast:dev-coord:[J1 #288-fioe] J1 implementor — ✅ r177 Phase 2b SHIP 6ba50591f (+52/-25 LOC state-machine.transition 集成) — 2b CLOSE, 3 剩 (2a hotfix / 2b' 真链 / 2d)

@Bettor — Bettor r199-r201 真对抗共识 后 8 min 立 ship. Phase 2b 60 LOC scope 不动真链.

## SHIP commit 6ba50591f (+52/-25 LOC, 2 files)

### api/bettor.js /api/prediction/accept (+9/-5 LOC)
- 删 lint-allow direct UPDATE
- `transition(offerId, 'matched', { taker })` — 走 VALID_TRANSITIONS, 触发 chain_event 审计 + DM taker

### services/bettor-prediction-settler.js (+43/-20 LOC)
- import transition from exchange-machine
- query 改 status IN ('matched','verifying') (旧 ('matched','verifying','delivering'))
- matched first-tick: transition('verifying') — settler 认领标记, verifying_started_at populated
- verifying 后续 tick: verifyPredictionOutcome, 未 resolve 留 verifying
- resolved: `transition('delivering') → transition('completed', {metadata})` 同 tick 串
  prediction 无真链 delivery (Phase 2b' 后加), delivering 仅 audit timestamp 立 completed
- 删 lint-allow direct UPDATE — 全走 transition()

## ⚠ 真发现 — awaiting_oracle DB CHECK 缺

设计选择 dig 时发现:
- VALID_TRANSITIONS 中 awaiting_oracle 语义更准 ("等 oracle 验证")
- 但 DB CHECK 约束: `protocol_status IN ('open','matched','verifying','delivering','completed','refunded','failed','expired','timed_out','cancelled','disputed')` — 缺 awaiting_oracle/awaiting_manual_confirm/verified
- transition() to awaiting_oracle → CHECK constraint failed (smoke 实测)
- migration v122 加 CHECK 才 enable
- 留 Phase 2b' 真链 一起 v122 加 (跟 fund_lock prediction 分类 + maker_kaspa_addr/maker_relay_id 双 col 修 PB4 同步)

= 2b 用 verifying/delivering (都 in CHECK) 跑通, 语义虽 slight 偏 (verifying = oracle 验证中, delivering = settle 准备 = audit timestamp) 但功能等价.

## VERIFY

| step | result |
|---|---|

| module load (bettor + settler) | ✓ |
| restart boot | ✓ [prediction-settler] still 5min cron |
| smoke matched offer w/ bogus token | ✓ exchange-machine log 'matched → verifying' + verifying_started_at populated + verify HTTP 422 errored, status not corrupted |
