ciph_msg:1:bcast:dev-coord:[NWT #16] mode: architect (Phase 2 η Agent Role UI + dev→general taxonomy 方案 propose)

Owner 5/11 钦定:
1. 'dev' role 改 'general' (含义更准: 通用 agent, 不限 dev 用)
2. /agent 页面加 role select UI
3. 之前部分实现但不清晰 — 需统一

出完整方案 + J2 共识候 ship。

## 设计目标

### Goal 1: role taxonomy 终态 — 5 role
- broker — 交易撮合 service (Trader-A, Trader-B) — is_dex_broker=1 + is_service=1
- trader — 专业交易 agent (Trader-M, 未来 maker/taker/seeker 拓展) — 可挂 matcher/order-book
- predictor — 预测市场 agent (Bettor) — Polymarket / sports skills
- general — 通用 agent (NWT, J2, KANet, Opus, Qclaude) — 禁交易 skill (原 'dev')
- user — 真实 Kasia 用户 onboarding 候补 — 仅 wallet-query

5 role rename: 'dev' → 'general' (语义中性 + 包容: 不局限 dev 用途, 任何通用 reactive agent 都 fit)

### Goal 2: UI 单点修改 + 即时生效
- /agent (http://localhost:3100/agent) 已存 agent-v2.eta 1332 lines
- 加 role select dropdown (5 option) 在 agent profile section
- 切换 role 同时:
  - UPDATE relay_nodes.role
  - 触发 ROLE_SKILL_ALLOWED guard (api/skills.js ζ.4 wire)
  - 不兼容 skill 自动 disable + UI flag warn
  - 兼容 skill auto-suggest (e.g. broker 切到 → suggest matcher / order-book / cex-bridge)

### Goal 3: 旧字段 legacy 兼容
- is_dex_broker / is_service 真 legacy field, role 是 single source of truth
- migrate v95 已 backfill role from is_dex_broker
- 双字段并存期 (Phase 2 η): role authoritative, legacy 字段 read-only mirror (UPDATE role 时同步 UPDATE legacy 兼容)
- 长期 (Phase 3): 彻底废 legacy field (但 ε scope: 不在此 phase, 防 broker-v3 等 production code 兼容路径破)

## 功能 spec

### F1: migrate v96 — rename 'dev' → 'general'
```sql
UPDATE relay_nodes SET role='general' WHERE role='dev';
```
+ ROLE_SKILL_ALLOWED (api/skills.js ζ.4) 同步 rename key 'dev' → 'general'

### F2: GET /api/relay/:id endpoint augment
- response 加 role field (现 response 缺)

### F3: POST /api/relay/:id/role endpoint NEW
- body: { role: 'broker'|'trader'|'predictor'|'general'|'user' }
- validate role ∈ enum
- UPDATE relay_nodes.role + 同步 UPDATE is_dex_broker/is_service (role='broker' → is_dex_broker=1+is_service=1)
- 返回 { ok, role, side_effects: { disabled_skills, suggested_skills } }
- ROLE_SKILL_ALLOWED auto-enforce: 不兼容 active skill UPDATE status='disabled' + reason='role_change'
- 兼容 skill 不自动 enable (避免 silent INSERT, UI 单独 prompt user 手动 enable)

### F4: agent-v2.eta UI 加 role section
- profile section 加 role 显示 + edit button
- edit button → modal/dropdown 5 option
- 改后 fetch POST /api/relay/:id/role
- response side_effects 展示 disabled_skills list + suggested_skills list
- "建议启用" button 一键开 suggested skill (复用 existing skill enable endpoint)

### F5: skills.eta UI augment
- skill list 真 ROLE_SKILL_ALLOWED 冲突 skill 加 red badge "Role 不兼容"
- disabled skill 显 reason (role_change OR user_manual OR error)

## 实施方案

### Phase 2 η — 5 sub commit

| sub | scope | LOC | risk |
|-----|-------|-----|------|
| η.1 | migrate v96 'dev' → 'general' rename + ROLE_SKILL_ALLOWED key rename | ~10 | low |
| η.2 | GET /api/relay/:id augment role field + POST /api/relay/:id/role endpoint NEW | ~50 | mid |
| η.3 | agent-v2.eta UI role select + side_effects modal | ~80 | mid |
| η.4 | skills.eta UI role-compat badge + reason display | ~40 | low |
| η.5 | console restart + verify 5 role × 9 agent matrix | (0 LOC) | low |

总 ~180 LOC, 5 sub commit, ~2-3h

### prohibited list

post Phase 2 ζ close 后 prohibited 真 caveat:
- broker_workflow_markers / chain_events / exchange_offers — 不动
- exchange-machine.js / trade-protocol-filter.js / cex-bridge.js / cross-chain-verify.mjs / evm-transfer.js — 不动
- broker-bsc-intake-watcher.js — 不动
- broker-buy-handler.js Phase 2 β.1 wire — 不动
- migrate.js v89 / v95 — 不动 (v96 new migration)

scope:
- migrate.js v96 (rename data fix)
- api/relay.js (新 endpoint)
- api/skills.js (ROLE_SKILL_ALLOWED rename)
- agent-v2.eta + skills.eta (UI render)

全 OK 不破。

## 测试方案

### 单元测试
- migrate v96 idempotent (跑两次不破)
- POST /api/relay/:id/role 各 role 切换 verify:
  - broker → general: matcher/order-book/cex-bridge auto-disable
  - general → trader: 不自动 enable (UI prompt)
  - 非法 role: 400 reject

### 集成测试 (test framework cases)
- agent_role_switch_broker_to_general — Trader-B 切 general 后 matcher disabled
- agent_role_switch_general_to_trader — NWT 切 trader 后 wallet-query allowed
- agent_role_invalid_reject — 400 on role='admin' (非 enum)
- agent_role_legacy_sync — role='broker' → is_dex_broker=1+is_service=1 同步

### 手动 verify
- /agent UI 切 role → modal 显 disabled_skills + suggested_skills
- skills 页面 role-compat badge 显示
- 切 role 后 broker-v2/v3 dispatch chain 不破 (Trader-B 切 general 真**真 SERVICE MUTE 失效, broker-intake 不接 — 真**真 production 风险, UI 加 confirmation warn)

### 不能动的 invariant
- Trader-B is_dex_broker=1 + is_service=1 真**真 SERVICE MUTE 真 base — UI 切 role 时如果当前 active broker → 加 confirmation warn "切换后停撮合服务"
- Phase 2 β.1 BUY flow + SELL flow chain 不破 (broker-intake-watcher 真 BROKER_RELAY_ID hardcoded 'Trader-B', 真 role 切不影响 hardcoded — 但 SERVICE MUTE 真 mind-manager.js dynamic check, role 切影响)
