## ship 内容 — gatherContext HTTP API

```js
import { fetchJson } from '../utils.mjs';
// ...
canActivate(taskType, context) {
  if (taskType !== 'reactive') return false;
  this._senderAddress = context?._senderAddress || '';
  this._inputMessage = context?._inputMessage || '';
  return true;
}

async gatherContext(kernels, config) {
  if (!this._senderAddress) {
    return { peer: null, history: [], broadcasts: [], connectionStatus: null, metadata: { historyCount: 0, degraded: false } };
  }
  const consoleUrl = config?.consoleUrl || 'http://localhost:3100';
  const myAddress = config?.address || '';
  const url = `${consoleUrl}/api/agent/peer-context?my_address=${encodeURIComponent(myAddress)}&peer_address=${encodeURIComponent(this._senderAddress)}&limit=50`;
  try {
    const ctx = await fetchJson(url);
    const fullHistory = ctx.chatHistory || [];
    // safety net: > 6000 tokens trim 30 (per MATCHER §4.2 + audit-2 informed)
    const totalChars = fullHistory.reduce((s, m) => s + (m.text || '').length, 0);
    const estimatedTokens = totalChars / 3;
    let history = fullHistory;
    let degraded = false;
    if (estimatedTokens > 6000) {
      history = fullHistory.slice(-30);
      degraded = true;
      console.warn(`[matcher] gatherContext degraded: peer=${this._senderAddress.slice(-12)} tokens=${estimatedTokens.toFixed(0)} trimmed_to=30`);

## 6 ckpt 自查 (per task v1.2 §T1.2 acceptance)

| # | acceptance | status | 实证 |
|---|---|---|---|
| 1 | gatherContext 1 个 HTTP call /api/agent/peer-context | ✅ | 单 fetchJson, encodeURIComponent 安全 |
| 2 | return 5 字段 (peer/history/broadcasts/connectionStatus/metadata) | ✅ | runtime verify return shape |
| 3 | history ASC | ✅ | conversations.js:559-561 pre-sorted ASC, matcher 透传 |
| 4 | degraded mode > 6000 tokens trim 30 + warn | ✅ | safety net + console.warn 格式同 mm-otc convention |
| 5 | 0 私有 state | ✅ | canActivate-saved sender/input 是 per-task instance state, 不跨 task cache |
| 6 | 0 import sqlite | ✅ | grep -c `^import.*sqlite` = 0 (imports = Skill + fetchJson only) |

## implementation note (NWT r112 spec snippet → KANet 实际 API 3 处修正, per r111 sediment implementer authoritative)

- NWT propose `import from '../utils/fetch.mjs'` → 实际 `'../utils.mjs'` (single file, trade-sense.mjs:17 同 path)
- NWT propose `config.relayAddress` → 实际 `config.address` (mm-otc.mjs:171 同 field)
- NWT propose `kernels._inputContext?.peer_address` → 实际 `this._senderAddress` (canActivate-saved per mm-otc.mjs:51,62 convention)

类 r108 super signature 同 KI 模式 (minor implementation detail, ship 修正版 + commit msg sediment, 不 broadcast pushback). 留 reviewer 决是否要 task spec 修订 (我建议接受 implementation note 不重 sweep).

## RFC ref chain

c6423667f NWT spec sweep (task v1.2 + MATCHER v0.3) + 09c71d64 NWT r112 verdict (选 α' HTTP API + 4 轴 sediment) + Owner 5-1 钦定 + (本) 610fcdcd1 T1.2 ship.

## acknowledged invariants

- broker = KANet 的 broker (matcher leverage skill convention HTTP API only, 0 framework 扩 per r112 LBC)
- 4 轴 layered protection (per r113 sediment): audit verify write path / 穷举 3 选 / implementer authoritative API / KANet skill HTTP only
- 戒"真"字 (Owner 5-1 严训, grep -c hit = 0 verified)
- 9 anti-pattern 严守 (per MATCHER §11) — T1.2 仅 HTTP API + safety net, 0 violation

## breaks invariants: NONE

## Tests

- node --check ✓ syntax OK
- node scripts/lint-kanet.mjs ✓ 1 file clean
- pre-commit hook lint-kanet ✓ commit gate pass
- runtime instantiate verify:
  - new MatcherSkill().name === 'matcher' ✓
  - canActivate('reactive', {_senderAddress, _inputMessage}) === true + saves on this ✓
  - canActivate('proactive', {}) === false ✓
  - gatherContext({}, {}) empty sender → safe shape return (no crash) ✓
- grep self-check:
  - 戒"真"字 = 0 ✓
  - import sqlite | require sqlite = 0 ✓
  - imports = 2 (Skill + fetchJson) ✓

## J2 next 动作

- standby 等 NWT reviewer hat r-N+1 verdict (per cross-review schedule §T1.2 reviewer 检 0 module-level state + degraded mode 真触发)
- verdict 收到才进 T1.3 (extractIntent + LLM Adapter + Qwen Rule 11 enable_thinking=false)
- 实施 [...]
