## 2026-09-02 — FB-01 智能兜底 P1（只读）
|
||||
|
||||
- **类型**：feature + test + docs
|
||||
- **做了什么**：意图未识别（`assistant.reply`/`unknown` 分支）时不再只回固定话术，而是拉起 Pi headless 做**一次只读分析兜底**（方案 S1/S5 进产品路径，草稿语义，不写主干世界）。
|
||||
- `server/agent_core/fallback_lane.py`（新建，moduleId: core-fallback-lane）：兜底编排器——`propose_reply` 唯一接线入口（绝不抛出）、FallbackConfig/from_env、三重熔断（超时 90s / 步数 30 / 输出 2MiB）、白名单环境清洗 + `PI_CODING_AGENT_DIR` 配置圈禁 + taskkill 进程树回收、模型端点协商（GET /models，避开 P0 实测 404 坑，缓存 300s）、成败只看事件流 stopReason（pi 退出码恒 0 不可信）。
|
||||
- `server/integrations/pi_bridge.py`（新建，moduleId: integ-pi-bridge）：围墙内工具桥——注册表只暴露 fs_read / aps_query（快照制）/ report_emit 三个只读项（写类工具刻意不登记）；callId 凭证账（calls.jsonl，入参只落 sha256 摘要）；报告引用校验（引用不存在的 callId = forged_citation 物理判败）；fs_read 限 run 目录（resolve + is_relative_to）；任务简报模板（USER_REQUEST 隔离标记防注入）。
|
||||
- Harness：`_POWER_MAP`/`_POLICY_DESC` 各纯追加一行 `agent.fallback.propose = P1`（仅权力登记动作名，不是意图枚举成员，contracts.py 未动）。
|
||||
- FF-01 开关：`FEATURE_CATALOG` 追加 `fallback`；新增 `_DEFAULT_OFF_KEYS={"fallback"}`——文件缺失/损坏/未配置/非 bool 时 fallback 默认 **False**（会拉起外部 LLM 子进程产生 token 成本，与其余键 fail-open 相反，有意取舍）；`/api/features` 响应追加 `defaultOff` 字段显式标注。
|
||||
- 接线：`workflow.py` `assistant.reply/unknown` 分支 +8 行——开关开且意图未识别 → `propose_reply`；返回 None（开关关/空 query）时原路径逐字节不变；失败 = 原话术 + 一行显式失败说明（审计留痕）。
|
||||
- **设计张力处置（简报层）**：callId 凭证由编排器围墙外事后签发，真实 Pi 无法获知其值——原简报「引用必须标注 callId」会把真实路径误判 forged。处置：任务简报撤销强制标注，改为明示「凭证不可获知、不得编造、出现不存在的编号即判伪造成果整轮失败」；校验硬失败语义不动，伪造识别能力不变。
|
||||
- **验证**：`tests/golden/test_fallback_lane.py` + `test_feature_flags.py` **19 passed**（13 兜底全确定性 fake runner + 6 开关，含伪造凭证判败/三重熔断/默认关三态/路径越界）；受影响回归切片（contract_sync/assistant/guidance/folder_pack/tool_runtime/gov_api + 聊天网关门禁 13 文件）**83 passed**；文档/端点门禁（doc_drift/health/openapi/rebuild）**20 passed**；全量黄金四批 **1084 passed / 1 failed**（`test_preference_features::test_extract_features_from_world` 为既有日期炸弹——dueDate 写死 2026-08-03/04，`server/knowledge/` 与该测试文件 `git diff` 均为零，与本轮无关，建议另开轮次修）；ruff 本轮新增/修改文件全绿（fallback_lane/pi_bridge/test_fallback_lane `All checks passed!`，修改文件零新增告警）。**冒烟复证（2026-09-02，Agent-H）**：真实端到端冒烟首轮抓到守卫模板注释行未转义花括号（`KeyError: ' block'`，fake runner 结构性盲区）与 node.CMD 垫片坑，修复（模板转义 + Windows 优先 `node.exe` + 新增 `test_write_guard_extension_real_template_format` 防回归）后原样代码复跑 `poc/pi-fallback/smoke/smoke_e2e.py` 七条判据全 PASS（真实 kimi-k2.6，run fb-20260902-075907-3af703，stopReason=stop，steps=2，13.0s，凭证 valid，审计 SUCCESS 落租户世界哈希链，收尾零残留）——详见 `poc/pi-fallback/P1-SMOKE.md` §7，**P1 GO**。
|
||||
- **影响分析**：GitNexus MCP 不可用，按 P1-DESIGN §7 rg 盘点 + 人工复核——harness.py 纯追加 LOW；feature_flags.py 产品调用方仅 `/api/features`（响应纯增量），三条 all-enabled 既有断言同轮修复 MED；workflow.py 聊天热路径接线 MED（缓解：默认关 + propose_reply 不抛 + 90s 硬熔断，开关关时逐字节不变已被测试断言）。无 HIGH/CRITICAL。
|
||||
- **文档同步**：docs/architecture/harness.md 权力矩阵 + `/api/features` 条目 + 变更记录、新建 docs/architecture/fallback.md（登记进 architecture/README.md 索引）、本节。
|
||||
- **边界**：P1 不做写操作/确认卡执行/pi 进程内实时工具/异步回投/桌面打包/SSE 转发；真实 pi 端到端冒烟未做（本轮全 fake runner，需带 key 环境按 P0 方法补）；凭证引用从「强制」降级为「出现即必须是真」的防伪绊线（见 fallback.md 凭证语义节）；token 预算以输出字节数近似。协同交接物：`poc/pi-fallback/`（GOAL-P1 / P1-DESIGN / P1-IMPL-NOTES / P1-VALIDATION）。
|
||||
- **发布动作**：无 commit/push/merge/publish。

# 智能兜底（Pi Agent）
|
||||
|
||||
> 对齐《Pi-Agent兜底能力详细方案》§4/§6 与 `poc/pi-fallback/`（GOAL-P1 / P1-DESIGN / P1-IMPL-NOTES / P1-VALIDATION）。
|
||||
> 落地态：**P1 只读兜底**（方案 S1 意图未识别 / S5 自由分析进产品路径）。
|
||||
|
||||
## 定位
|
||||
|
||||
用户在对话里说了一句产品功能覆盖不了的话（意图识别落到 `assistant.reply`/`unknown` 分支）时，
|
||||
不再只得到固定话术，而是拉起 Pi headless 做**一次只读分析**，返回一份真实产出的分析草稿：
|
||||
|
||||
- **草稿语义（P1）**：产物只是回复文本与 run 目录归档，**不写主干世界**；
|
||||
回复带 `[智能兜底 · 草稿]` 前缀与「未改动任何数据」声明。
|
||||
- **失败显式**：任何失败（熔断/不可用/伪造凭证/空报告）都回退原话术 + 一行中文化失败原因，
|
||||
并写 FAILED 审计；`propose_reply` 绝不抛出，聊天链路永远有回复。
|
||||
- **接线点唯一**：`server/aps_domain/workflow.py` 的 `assistant.reply/unknown` 分支
|
||||
→ `fallback_lane.propose_reply()`；开关关时返回 `None`，原路径逐字节不变。
|
||||
|
||||
## 组件
|
||||
|
||||
| 组件 | moduleId | 职责 |
|
||||
| --- | --- | --- |
|
||||
| `server/agent_core/fallback_lane.py` | core-fallback-lane | 兜底编排器：触发判定、任务简报、拉起/回收 Pi 子进程、三重熔断、环境清洗、run 目录管理、审计 |
|
||||
| `server/integrations/pi_bridge.py` | integ-pi-bridge | 围墙内工具桥：只读工具注册表、callId 凭证账（calls.jsonl）、报告凭证校验、只读快照导出、任务简报模板 |
|
||||
|
||||
Harness 登记：`agent.fallback.propose = P1`（见 [harness.md](./harness.md) 权力矩阵）。
|
||||
它只是权力登记动作名，**不是意图枚举成员**（`IntentName` 封闭 Literal 未变），LLM 无法产出它。
|
||||
|
||||
## 开关语义（FF-01 `fallback`，默认关）
|
||||
|
||||
- 配置：复用 FF-01 文件化开关（`server/data/features.json`，`APS_FEATURES_PATH` 可覆盖）；
|
||||
`{"features": {"fallback": true}}` 显式开启。
|
||||
- **默认关**：`feature_flags._DEFAULT_OFF_KEYS = {"fallback"}`——文件缺失/损坏/未配置/取值非 bool
|
||||
时 `fallback` 默认 **False**，与其余键的 fail-open **相反**；`/api/features` 响应携带
|
||||
`defaultOff` 字段显式标注。
|
||||
- **为什么相反**：fallback 会拉起外部 LLM 子进程并产生 token 成本，默认开会在无模型/离线现场
|
||||
制造意外副作用；兜底是增强能力而非主干功能，关了只回到现状话术，系统不失能（有意取舍，
|
||||
fail-open 的「损坏不锁死」保护对该键反向成 fail-closed）。
|
||||
- 查询入口 `fallback_feature_enabled()` 直接消费 `load_feature_flags()` 单一事实源；
|
||||
任何异常 → False（宁可误关不可误开）。
|
||||
|
||||
## 运行目录
|
||||
|
||||
根：`<APS_FALLBACK_DIR>` 或 `path_under_data("fallback")/`
|
||||
（web=`server/data/fallback/`，desktop=`~/.aps/data/fallback/`）。
|
||||
|
||||
```
|
||||
<根>/
|
||||
├── pi-home/models.json # PI_CODING_AGENT_DIR 配置圈禁；apiKey 只写环境变量名引用，不落明文
|
||||
└── fb-YYYYMMDD-HHMMSS-xxxxxx/
|
||||
├── inbox/ # 注入区：snapshot.md / orders.csv（export_snapshot 只读快照）
|
||||
├── work/ # pi 子进程 cwd 圈禁于此
|
||||
├── outbox/report.md # 产物唯一出口
|
||||
├── events.jsonl / orchestrator.log / result.json / calls.jsonl
|
||||
└── guard-<runId>.ts # 本次运行加载的守卫扩展（随运行归档）
|
||||
```
|
||||
|
||||
配置环境变量（`APS_FALLBACK_*`）：`DIR` / `PI_CLI`（默认复用 `poc/pi-fallback/runtime/` 的 P0 安装，
|
||||
打包留后续阶段）/ `PI_HOME` / `NODE` / `MODEL` / `TIMEOUT_SEC`(90) / `MAX_STEPS`(30) /
|
||||
`MAX_OUTPUT_BYTES`(2MiB)。模型 key 复用 `LLM_BASE_URL`/`LLM_API_KEY`/`LLM_MODEL`，只经白名单清洗后的
|
||||
子进程环境注入，**绝不打印、绝不落盘**；`resolve_model()` 经 `GET /models` 协商（避开 P0 实测的
|
||||
404 坑），进程内缓存 300s。
|
||||
|
||||
node 解析顺序（`_resolve_node`，P1 真实冒烟坑 B 对策）：① 显式 `APS_FALLBACK_NODE` 最高优先级
|
||||
原样命中；② 默认 `"node"` 且 Windows 时 `shutil.which("node.exe")` **优先于** `shutil.which("node")`
|
||||
——避开 PATH 中先于 node.exe 命中的 `node.CMD` 垫片（Popen 起 .cmd 引号语义会炸，pi 秒败，
|
||||
2026-09-02 冒烟实测）；③ 其余平台/兜底回退 `shutil.which("node")`。
|
||||
|
||||
## 三重熔断与成败判定
|
||||
|
||||
| 闸 | 上限 | 触发后果 |
|
||||
| --- | --- | --- |
|
||||
| 超时 | 90s（聊天同步预算；executor 线程内运行，不堵事件循环） | 杀进程树，`breaker:timeout(...)` 显式判败 |
|
||||
| 工具步数 | 30 | 同上，`breaker:max_steps(...)` |
|
||||
| 输出体量 | 2MiB | 同上，`breaker:max_output(...)` |
|
||||
|
||||
成败**只看事件流 stopReason**（`stop` 才为成功），绝不相信进程退出码（P0 实测 pi 恒退 0）；
|
||||
`stop` 但报告为空判 `error:empty_report`；runner 抛错/桥违规归并 `harness_error`；
|
||||
运行时不可用（无 node/pi/模型配置）判 `unavailable:<原因>`。
|
||||
|
||||
## 围墙与工具桥只读面
|
||||
|
||||
- **L1 工具层**：pi 启动参数只挂 `read,grep,find,ls` 只读四件套；守卫扩展在 pi 侧拦截
|
||||
`bash/edit/write` 全禁、文件工具路径限 run 目录（拦截落 guard-blocked-calls.jsonl）。
|
||||
- **L2 目录圈禁**：子进程 cwd=work/；桥侧 `handle_fs_read` resolve + is_relative_to，
|
||||
越界（`../`、绝对路径逃逸）抛 `ToolBridgeViolation`。
|
||||
- **L4 环境清洗**：白名单制子进程环境，剥离 `CONDA_*`/`PYTHON*`/`PIP_*`/`VIRTUAL_ENV*`。
|
||||
|
||||
桥注册表（`TOOL_REGISTRY`）P1 只暴露三项，写类工具（fs_write/shell_run/aps_invoke 等）
|
||||
**刻意不登记——不登记即不可见，这是墙的一部分**：
|
||||
|
||||
| 工具 | 权力 | 语义 |
|
||||
| --- | --- | --- |
|
||||
| `fs_read` | P0 | 读 run 目录内文件（真实 pi 侧由内置 read/grep/find/ls + 守卫扩展实现） |
|
||||
| `aps_query` | P0 | 快照制：run 启动时把只读世界视图导出为 inbox/snapshot.md + orders.csv，pi 经 fs_read 消费；**不做 pi 进程内实时查询工具** |
|
||||
| `report_emit` | P1 | 产物唯一出口：编排器把 pi 最终文本写 outbox/report.md |
|
||||
|
||||
**callId 凭证**：每次工具事件由编排器在围墙外签发 `call-<uuid4>` 落 calls.jsonl
|
||||
（入参只落 sha256 摘要，不落明文；桥 callId 与 pi 事件流 toolCallId 双向登记）。
|
||||
报告引用校验 `validate_report_citations()`：**报告中出现的每个 callId 必须真实存在，
|
||||
否则判 `forged_citation` 物理失败**（伪造成果防线，安全性质不可降级）。
|
||||
|
||||
**凭证语义的已知限制与 P1 处置（2026-09-02）**：凭证由编排器从事件流**事后签发**，
|
||||
真实 Pi 进程内的 LLM 无法获知其值——若简报强制要求标注 callId，真实引用必然被误判 forged
|
||||
（设计张力，P1-IMPL-NOTES 遗留风险 #2）。P1 处置 = **任务简报不再要求标注凭证**，并明示
|
||||
「凭证由围墙外签发、你不可获知、不得编造；出现不存在的凭证编号即判伪造成果整轮失败」。
|
||||
即引用从「强制」降级为「出现即必须是真」的防伪绊线；报告数字的可靠性改由
|
||||
「唯一数据来源 = inbox 只读快照」保证。伪造 callId 识别能力不变
|
||||
（`test_forged_callid_rejected` 保持绿）。
|
||||
|
||||
## 审计
|
||||
|
||||
- 完成时 1 条 `TOOL agent.fallback.propose`（成败都写，power=P1）：rationale 携带
|
||||
runId / queryDigest（sha256 前 16 位，不落原话明文）/ stopReason / steps / elapsedSec /
|
||||
citationCheck 计数 / runDir / reportPath；`evidence_refs=["fallback-run:<runId>"]`。
|
||||
- 每个工具事件 1 条 `TOOL tool.run`（actor=`pi-fallback:<runId>`，power=P0）——
|
||||
GovConsole「工具调用」视图零改动即可见。
|
||||
|
||||
## 边界（P1 明确不做）
|
||||
|
||||
1. 一切写操作（fs_write/shell_run/aps_invoke/checkpoint_create 不登记）；
|
||||
2. 确认卡执行路径（`agent.fallback.execute` 不登记、不实现）；
|
||||
3. pi 进程内实时工具 / HTTP 桥回调（aps_query 只做启动时快照，不新增网络监听面）；
|
||||
4. 后台/异步兜底与结果回投（同步 + 90s 硬上限是有意取舍）；
|
||||
5. 桌面打包 / sidecar 集成（路径已可配置，sidecar.cjs 未动）；
|
||||
6. SSE 实时转发 pi 事件、token 预算闸（以输出字节数近似）、端口级网络限制、junction/8.3 短路径防护；
|
||||
7. S2（已登记意图执行失败的兜底）、S3/S9 写路径、真实 pi 端到端冒烟（需带 key 环境，见
|
||||
`poc/pi-fallback/P1-VALIDATION.md` 未验证清单）。
|
||||
|
||||
## 验证
|
||||
|
||||
`tests/golden/test_fallback_lane.py` 13 例全确定性（fake runner 注入 +
|
||||
tmp_path 隔离 + 清 LLM env，不依赖真实 node/pi/网络/LLM）：开关关原行为不变 /
|
||||
开关开 propose 成功 / 未登记意图仍拒绝 / 审计链不断 / 三重熔断显式失败 /
|
||||
伪造凭证判败 / runner 异常显式失败 / 默认关三态 / 路径越界拦截 / 运行时不可用回话术。
