+# 文件库 · 开工计划（v1.0）
+
+> 配套文档：《文件库-接口契约.md》(v0.1，仓库根目录)。本计划已吸收规划顾问评审意见，包含开工前必须先冻结的**架构收口决策 D11–D19**（回写契约 v0.2 时并入）。
+> 工期按 1 人全栈估算；前端从 Phase 2 后可并行。
+
+## 开工判定
+
+**可以开工。** 四个外部依赖（版本包 / Group / 审计 / 平台身份）全部有契约可依、可 mock 并行开发；无阻塞项。唯一前置：本文件的 D11–D19 决策在写第一行 schema 前过一遍（半天，自查即可，有异议再升级）。
+
+## 架构收口决策（新增，先冻结再动工）
+
+| 编号 | 决策 | 理由 |
+|---|---|---|
+| D11 | `creator` 是 Node 的**不可变列**，创建时同时落一条 Manage grant；独立权限开关关闭时，**creator 的 Manage 仍生效**，其余项目级 grant 冻结不参与计算 | 否则 creator 可能被自己关掉的开关锁死 |
+| D12 | 移动节点授权 = **本节点 Manage + 目标父 Edit+**；移动在事务 + Postgres 咨询锁内完成，防并发成环 | 预检环检测在并发下不安全 |
+| D13 | Group resolve 失败返回 **503**（不伪装 404/403）；每次 HTTP 请求 fresh resolve，不跨请求缓存；单请求内多次校验合并为一次调用（此点与 Group 团队确认，OPEN-9） | 依赖故障 ≠ 无权限；契约 G4 要求实时 |
+| D14 | 命名规则：NFC 归一化、trim、≤128 字符、禁 `/` 与控制字符；**活跃兄弟节点大小写不敏感唯一**；根节点全局唯一 | 缺命名规则必有脏数据 |
+| D15 | 删除 = 只给被删节点打标，后代**不递归打标**，靠"任一祖先已删"过滤；所有查询链路强制此过滤（含递归 SQL，不只靠 Prisma middleware） | 递归打标的写放大与恢复复杂度不可控 |
+| D16 | `baseVersion` 为**文件级版本**（GET file 返回的 version）；无关文件的提交不产生冲突 | 与 C1 `head(dir, filePath)` 语义一致 |
+| D17 | breadcrumb 只暴露用户有 View 的祖先名称；无权限祖先显示占位符 `…`，不暴露名字 | 404 不泄露语义（D8）延伸到面包屑 |
+| D18 | v1 **单副本部署**（git 仓库在本地磁盘）；多副本需共享存储或分片，后置 | 不解决不存在的扩展问题 |
+| D19 | 网站管理员**不隐式读内容**；force_adjust 凭 node id 操作（id 从审计或用户上报获得） | C4 已定的最小权限原则 |
+
+## 阶段计划
+
+### Phase 0 · 骨架与身份先行（1–2 天）
+
+- [ ] 过 D11–D19，回写契约 v0.2
+- [ ] repo 骨架 `server/` + `web/`，Postgres docker-compose，CI（lint / typecheck / vitest / 集成测试用真实 Postgres service container）
+- [ ] **JWT 中间件 + 本地 JWKS 测试服务 + 签名 token fixtures**（有效/过期/错 issuer/错 audience/错算法/未知 kid/轮换）——身份先行，不做"宽松 mock 身份"
+- [ ] 4 个 port 接口定义 + mock：`VersionStore`、`GroupResolver`、`AuditSink`（直写 outbox 表的实现就是真的，mock 的是对端服务）、`ExportAdapter`
+- [ ] fastify-swagger 接入，OpenAPI 骨架——**OpenAPI 随每个端点同步产出，不留到最后**
+- **验收**：骨架可 `pnpm dev` 起服务；本地 JWKS 六类 token fixture（有效/过期/错 issuer/错 audience/错算法/未知 kid）中间件行为全对；CI 流水线绿
+
+### Phase 1 · 数据模型与权限引擎（2–3 天）⚑ 心脏
+
+- [ ] Prisma schema：`Node`（parentId **权威** + id 编码的 materialized path 派生列，name 不入 path）、`Grant`、`ProjectIndependentSettings`、`OutboxEvent`（含 attempts/nextAttemptAt/lease/lastError，relay 字段一次到位）、`ExportJob`
+- [ ] 数据库约束：kind 枚举、项目无子节点、活跃兄弟名唯一（部分唯一索引，root 的 NULL parent 特殊处理）、活跃 grant 按 (nodeId, principalType, principalId) 唯一、独立设置仅项目
+- [ ] **纯权限 reducer**：输入已解析的 grants + 祖先链 + 用户组集合，输出 role|null；不碰 DB/网络。fast-check 属性测试：max 单调、加 grant 只升不降、祖先继承、toggle 行为、顺序无关、软删过滤
+- [ ] 数据获取层 + `effective(user, node)` 组装
+- [ ] 树操作服务：create（creator 自动 Manage、root 仅管理员且必带 ≥1 Manage）、rename、move（D12 事务+咨询锁）、soft delete（D15）、breadcrumb（D17）
+- **验收**：并发对移（A→B 与 B→A）、移动+并发建子、property tests、删除祖先过滤，真实 Postgres 全绿
+
+### Phase 2 · 树与授权 API（1–2 天）
+
+- [ ] nodes 端点组 + grants 端点组 + independent-permission 开关 + effective-permission 自查
+- [ ] 授权矩阵校验（契约 8.1：creator-only 授 Manage、Manage 不可动 creator、force_adjust 独立通道）
+- [ ] 全部写操作落 outbox 事件（C3 词汇表）
+- **验收**：契约 8.1 矩阵逐格 API 测试；D8 的 404/403/503 三分语义测试
+
+### Phase 3 · 仓库生命周期与文件 API（2 天）
+
+- [ ] 项目 provisioning 状态机 `PROVISIONING → READY | FAILED`：先建 DB 行（PROVISIONING）→ 调 `VersionStore.init`（幂等）→ 置 READY；失败可重试；孤儿仓库对账 job
+- [ ] 每项目写锁（Postgres 咨询锁，跨进程安全）——不假设版本包能跨进程串行
+- [ ] 路径安全：canonical 后必须落在项目根内、拒绝 `.git`、禁 symlink 逃逸、路径长度上限
+- [ ] 上传限额（单文件 10MB / 单项目配额，数值 OPEN-5）+ 流式接收
+- [ ] files 端点组全量（list/read/upload/commits→409/diff/history/delete）+ 双客户端冲突 e2e
+- **验收**：DB/git 故障注入（init 失败、提交后崩溃）→ 对账能收敛；路径穿越语料库测试全拒
+
+### Phase 4 · 外部集成（1–2 天）
+
+- [ ] `GroupResolver` HTTP client：超时/5xx/429/畸形 JSON/万级 group 的故障注入测试；失败 → 503（D13）
+- [ ] Audit relay worker：租约领取、指数退避、eventId 幂等、重启恢复、积压告警
+- [ ] 导出 job：状态机 + 轮询 + 下载权限校验；`ExportAdapter` 桩（参数 OPEN-6 未定前**不计入完成标准**）
+- **验收**：relay 重启不丢不重（对端幂等）；group 故障时写操作 503、读操作按 D13
+
+### Phase 5 · 前端（3–5 天，Phase 2 后并行启动）
+
+- [ ] 登录（平台 SSO 占位 + 本地 JWKS 直通开关）
+- [ ] 树浏览（懒加载 + 分页）、breadcrumb（D17 占位符）、创建对话框（类型 + 批量授权选择器，Group search 接 C2）
+- [ ] 权限管理面板（按 8.1 矩阵控制可选项，creator 标识）
+- [ ] 文件页：查看/上传/下载/历史列表（编辑 UI 不归我方，留对接位）
+- [ ] 导出按钮 + job 轮询
+- **验收**：无权限节点全链路不可见；授权面板不会送出矩阵禁止的组合
+
+### Phase 6 · 硬化与交付（1–2 天）
+
+- [ ] 404/403/503 全端点核对；并发与重试幂等抽查
+- [ ] 备份脚本（DB + git 仓库一致性快照）、健康检查（DB/JWKS/磁盘/Group）、磁盘水位告警
+- [ ] OpenAPI 终稿 + 部署脚本 + 一页运维手册
+
+## 里程碑
+
+| 里程碑 | 内容 | 累计工期 |
+|---|---|---|
+| M1 | Phase 0–1：骨架 + 权限引擎 + 树操作可跑 | ~4 天 |
+| M2 | Phase 2–3：后端 API 全量（含文件冲突流） | ~7 天 |
+| M3 | Phase 4：外部集成（导出不计） | ~9 天 |
+| M4 | Phase 5–6：前端 + 硬化，可交付 | ~14–18 天 |
+
+## Mock 保真红线（mock 可以顶，但不许骗）
+
+| Mock | 不许掩盖的事 | 真身到位后的契约测试 |
+|---|---|---|
+| VersionStore | 磁盘延迟、半初始化、锁残留、跨进程并发 | 真包跑临时仓库：并发 commit/init 重试/遍历与 symlink 语料 |
+| GroupResolver | 超时、5xx、畸形响应、大规模组集 | 故障注入 HTTP 桩全过；我方绝不自己推祖先 |
+| GroupSearch（前端选择器） | 与 resolve 是**两个独立端点**，不可用 resolve mock 顶替 | C2 `/groups/search` 真身到位后跑分页/空结果/超时 |
+| Audit 对端 | 重复投递、乱序、长时间不可用 | relay 重启恢复 + 对端幂等 |
+| JWT | issuer/audience/算法/轮换 | 本地 JWKS 全用例 |
+| ExportAdapter | 参数、幂等、耗时 | 参数定了再写，之前不算完成 |
+
+## Top 5 风险
+
+1. **DB/git 分裂**（崩溃导致元数据、仓库、审计三边不一致）→ provisioning 状态机 + 对账 job，Phase 3 前置
+2. **移动子树改变整树权限** → D12 事务+锁+源目标双授权，并发测试
+3. **creator/独立权限开关交互** → D11 先冻结
+4. **外部契约缺口**（导出参数、请求内 resolve 合并）→ OPEN 清单跟踪，mock 保真红线不许掩盖
+5. **存储滥用/路径逃逸** → 路径安全 + 配额进 Phase 3 验收，不拖到硬化
+
+## OPEN 清单（在契约文档基础上增补）
+
+- OPEN-9：单请求内合并多次 resolve 是否符合 G4"实时"语义（找 Group 团队确认）
+- OPEN-10：恶意软件扫描归属（我方/平台/不做）

-这 5 条是 `spec/` 这份语义母本的定位与约束,是本仓库一切工作的前提。
+这 4 条是本仓库的协作约定,是一切工作的前提。
 
-1. **角色 —— Lean 是研发侧的上游参照。**
+1. **角色 —— ADR 是决策真相。**
-   `spec/` 用 Lean 编写,是开发者(领域专家)与 coding agent **共用**的 spec 工具,用来沉淀产品各部件的**语义**。它**不进入产品运行时**——产品里"站在 Lean 这个位置"的那个 checker 用什么技术实现,尚未决定;但那个东西的语义,先在 `spec/` 里固定下来。
+   跨部件的语义决策只记录在 `docs/adr/`,一份决策一份 ADR,编号顺延、正文不改写历史。代码里的关键不变量用注释锚到 ADR 编号,保持可 grep。没有第二份权威文档。
 
-2. **对齐机制 —— Lean 只做上游参照。**
+2. **对齐机制 —— 人肉承载,无机器兜底。**
-   不做 extract / codegen,不派生 conformance test,CI 里**没有** spec→实现的 gate。实现对齐 spec,由"开发者 review + agent 巡逻 diff"这个人肉环节承载。
+   CI 只验各部件自身良构(build / test / clippy),**没有**决策↔实现的一致性 gate。实现对齐 ADR,由"开发者 review + agent 巡逻 diff"这个人肉环节承载。发现漂移,报告它,不要默默让其中一边将就另一边。
-   (CI 里的 `spec check` 只验 spec **自身**能否 type-check,即契约内部良构,不是 spec↔实现的对齐检查。)
 
-3. **资产性 —— 由 review 纪律承载,无机器兜底。**
+3. **形态 —— 自包含。**
-   这份仓库给你的是"精确、自洽、机器验内部良构的语义共识",**不是**"实现正确性保证"。spec 与实现之间那道缝,是我们自愿用人来守的——清醒地守,它就是资产;放任实现漂移而不回头同步,它就退化成最贵的过期文档。
+   凡 ADR 未明文规定的,开发者与 agent 双方都不该假设;遇到没覆盖的地方,**显式 surface** 出来让开发者决定。
 
-4. **形态 —— 它是人机共识的契约。**
+4. **深度判据 —— 只收录分歧点。**
-   契约必须**自包含**:凡契约未明文规定的,开发者与 agent 双方都不该假设。这比"文档"严格——type checker 会逼这份契约在结构上无洞。
+   一条语义该不该写进 ADR,取决于一句话:**"不写明,开发者与 agent 会不会各自做出不同假设?"** 会 → 进 ADR;显然的东西 / 纯 plumbing / 普通 CRUD 字段 → 不进(写进去只稀释信噪比、增加维护面)。
-
+   深度上限是**你愿意在每次实现变更时手动回头同步的量**——写得比你能维护的更深,多出来的部分会率先过期、反过来误导实现。
-5. **深度判据 —— 只收录分歧点。**
-   一条语义该不该写进 Lean,取决于一句话:**"不写明,开发者与 agent 会不会各自做出不同假设?"** 会 → 进契约;显然的东西 / 纯 plumbing / 普通 CRUD 字段 → 不进(写进去只稀释信噪比、增加维护面)。
-   深度上限不是 Lean 的表达力,而是**你愿意在每次实现变更时手动回头同步的量**——写得比你能维护的更深,多出来的部分会率先过期、反过来误导实现。
 
 ## CI
 
-`.gitea/workflows/spec-check.yml` 在每次 push / PR 时于 `spec/` 下跑 `lake build`,确保契约始终 type-check 通过(从第一天起就是"绿"的)。这是良构 gate,见宪法第 2 条。
-
 Rust checker 的本地与 CI 工具链由根 `rust-toolchain.toml` 固定;`.gitea/workflows/checker-check.yml`
 必须安装同一精确版本并执行 `cargo fmt --all --check`、Clippy `-D warnings` 与 workspace
 全测试。升级 Rust 时这两处必须在同一提交更新并通过完整 checker gate。

+# ADR 0026: Usage Fact Ledger
+
+## Status
+
+Accepted.
+
+## Context
+
+ADR-0022 pins the cost-attribution contract for the platform: token,
+provider-reported cost, run count, and duration are attributed by Organization,
+Project, Run, model, and Provider Connection; "missing provider cost remains
+unknown rather than zero." ADR-0021 scopes usage accounting as operational
+reporting, not payment collection (commercial billing stays deferred).
+
+The implementation today stores this as **one scalar per `AgentRun`**:
+`inputTokens`, `outputTokens`, `costUsd?`, `costSource?`, written once from the
+Claude Agent SDK's `result.total_cost_usd` when the run finishes. This is
+adequate for a single provider-reported model loop, but it cannot represent:
+
+- **External capability consumption** inside a run. PDF→Markdown bundle
+  conversion, audio/video transcription, OCR and similar media transforms are
+  not the main agent loop. They run as side effects of a run, may use a
+  different provider/model, may bill in non-token units (pages, seconds,
+  invocations), and may report cost through a different channel than the
+  OpenRouter gateway. Today there is no row to write that cost to — it would
+  either disappear or silently corrupt the run's single scalar.
+- **Multiple model calls within one run** (e.g. a sub-model invoked by a
+  tool, a gateway-side reroute). The scalar collapses them into one number.
+- **Pricebook derivation** after the fact. With only a final USD figure and no
+  `(provider, model, occurredAt, tokens)` fact, an operator cannot re-derive
+  cost from a price table when the provider did not report it.
+
+Treating each external call as a nested `AgentRun` was considered and
+rejected: `AgentRun` carries lock ownership (ADR-0002), session/provider/role
+binding (ADR-0017), admission/capacity semantics (ADR-0022), and the
+user-visible task boundary. External calls hold none of those. Making them
+`AgentRun`s would pollute run counts, admission, lock semantics, and session
+continuity, and would still not solve non-token metering.
+
+## Decision
+
+Introduce **`UsageFact`** as the single source of truth for billable
+consumption inside an `AgentRun`. An `AgentRun` owns zero or more
+append-only `UsageFact` rows; each row records one billable consumption event:
+
+- `kind` — `model_completion` (the main agent loop) | `external_capability`
+  | `tool_proxy`. The kind set is `OPEN`; new kinds must be surfaced, not
+  silently folded into an existing one.
+- `provider` — e.g. `openrouter`, `mineru`, `openai_whisper`.
+- `model?`, `inputTokens?`, `outputTokens?` — token metering, optional
+  because non-token capabilities have none.
+- `quantity?` + `unit?` — non-token metering (pages, audio_seconds,
+  invocations), coexisting with tokens rather than replacing them.
+- `costUsd?` + `costSource` — `provider_reported` | `pricebook_derived` |
+  `unknown`. `costUsd = null` means **unknown, not zero** (ADR-0022). When the
+  provider reported a cost, `costSource = provider_reported` and that value
+  wins. When only tokens are known, a later pricebook pass may derive
+  `costUsd` with `costSource = pricebook_derived`. When neither is possible,
+  `costSource = unknown` and `costUsd` stays null.
+- `occurredAt` — when the consumption happened; the pricebook derivation
+  depends on this, not on `AgentRun.finishedAt`, because an external
+  capability may complete before the run finishes.
+- `capabilityId?` — for `external_capability` facts, the registered capability
+  id (e.g. `pdf_to_md_bundle`, `audio_video_to_text`).
+- `correlationId?` — external request id for reconciliation / idempotency;
+  not part of the aggregation key.
+
+### Invariants
+
+1. **Append-only.** A `UsageFact` row is never updated or deleted. A cost
+   correction is a new row; the old row stays. `onDelete: Cascade` exists only
+   so a hard run delete (itself not a normal path) cleans up its facts.
+2. **Belongs to exactly one Run; never holds a lock.** A fact is a side-effect
+   ledger of one run, not a sub-run. External capability calls obey the same
+   boundary: their identity is `capabilityId + correlationId`, not `RunId`.
+3. **Missing cost ≠ zero.** Aggregation MUST NOT sum `null` `costUsd` as 0.
+   A run whose facts all have `costUsd = null` is "cost unknown" — reported as
+   `runsWithoutCost`, exactly as the pre-migration `costUsd = null` runs are
+   today. A run with at least one `costUsd`-bearing fact contributes its sum.
+
+### Rollup cache
+
+`AgentRun.costUsd / inputTokens / outputTokens / costSource` columns are kept
+as a **derived rollup cache**, not dropped:
+
+- Existing non-`/usage` readers (slash `/usage`, session detail, integration
+  tests asserting `run.costUsd`) continue to work without code changes for
+  historical runs.
+- On run finish, the writer writes the `UsageFact` row first and then mirrors
+  it onto `AgentRun` as two separate statements, not one transaction. The
+  fact is the truth, so it is written first; the cache is derived, so it is
+  written second. A crash between the two leaves the cache stale, but the
+  usage service re-reads `UsageFact` directly, so staleness is recoverable
+  (and the reverse order would lose the truth, which is not). Keeping the
+  fact insert and the run update in separate statements also avoids holding
+  the `AgentRun` row lock across the FK ShareLock taken by the insert, which
+  deadlocks against concurrent workspace teardown under the cascade path
+  `Organization → Project → AgentRun → UsageFact`.
+- The org/project usage service and the slash `/usage` command read from
+  `UsageFact` directly — they are the canonical aggregation path.
+
+### Migration
+
+A new `UsageFact` table is added. For every existing `AgentRun` with a
+non-null `costUsd` or non-null `inputTokens`/`outputTokens`, the migration
+inserts **one synthetic `model_completion` fact** carrying the run's
+provider, model, tokens, cost, and `costSource`. Its `correlationId` is the
+run id, so the row is identifiable as a backfill artefact. This keeps
+historical reporting correct under the new aggregation path. Pre-migration
+runs with no recorded cost remain `runsWithoutCost` by design, matching
+ADR-0022's "missing cost ≠ zero" rule and the existing migration
+`20260709143000_agent_run_cost_tracking`'s "no backfill" stance for the
+truly unrecorded.
+
+## Consequences
+
+- The billing model now supports external capabilities (PDF→MD, ASR, OCR, …)
+  without per-capability schema changes: a new capability is one new
+  `capabilityId` value and one or more `external_capability` facts.
+- `AgentRun.costUsd` is no longer the truth; it is a convenience cache.
+  Readers that need the truth (cost breakdown, per-capability attribution)
+  must read `UsageFact`. The cache MUST be kept consistent on the write path.
+- The capability registry, pricebook, and any commercial settlement remain
+  `OPEN` and out of pilot scope (ADR-0021). This ADR only pins the ledger
+  shape and invariants.
+- `usage.ts` and `/usage` now perform a join against `UsageFact` rather than a
+  single-table scan of `AgentRun`; the index on `(runId, occurredAt)` and
+  `(provider, model, occurredAt)` keeps the existing org/project/report
+  queries bounded.
+- Cost corrections (e.g. a provider rebills a run) produce a new fact row; the
+  rollup cache must be recomputed. The initial release writes facts once at
+  run finish and does not support post-hoc correction flows — that remains
+  `OPEN`.
+
+## Deferred
+
+- **Capability registry** as a first-class spec entity (`Spec.System.Capability`)
+  with org-scoped enable/disable, input/output contracts, metering schemas,
+  and org-exclusive credentials (ADR-0024 alignment). This ADR only reserves
+  the `capabilityId` field and the `external_capability` fact kind.
+- **Pricebook** — a versioned price table keyed by `(provider, model, unit)`
+  with time validity. Required to actually produce `pricebook_derived` costs;
+  until then, facts without provider-reported cost stay `unknown`.
+- **Post-hoc cost correction flow** — append-only today; correction UI and
+  rollup recompute are `OPEN`.
+- **Commercial billing, invoicing, settlement** — still deferred per ADR-0021.

+# ADR 0027: External Capability Registry
+
+## Status
+
+Accepted.
+
+## Context
+
+ADR-0026 introduced the `UsageFact` ledger with a `kind = external_capability`
+fact and a `capabilityId` field, but deferred the capability registry itself.
+Two concrete needs now force the issue:
+
+- **PDF→Markdown bundle** conversion (and, imminently, audio/video→text)
+  must run as a side effect of an `AgentRun`, bill in non-token units
+  (pages, seconds), use a different provider than the model loop, and report
+  cost through a different channel. It is not a sub-run (ADR-0026 rejected
+  that) and not a model-provider call (it does not speak the Anthropic/
+  OpenRouter protocol).
+- The Agent already has a Bash tool. Without a first-class capability seam,
+  the path of least resistance is for the agent to shell out to ad-hoc
+  scripts that embed API keys, write to arbitrary paths, and report nothing
+  to the ledger. That is exactly the unattributed, uncontained external
+  consumption ADR-0022/0026 exist to prevent.
+
+The model-provider connection (`OrganizationProviderConnection`, ADR-0024)
+is the wrong seam for these services:
+
+- Its payload schema (`baseUrl` + `authToken` + `anthropicApiKey`) and
+  readiness probe (`/v1/models?supported_parameters=tools`) are specific to
+  OpenRouter/Anthropic. MinerU, Whisper, and future OCR/ASR services have
+  different auth shapes (an API token, optionally a project id) and no
+  `/v1/models` endpoint.
+- Its uniqueness key is `(organizationId, providerId)` where `providerId`
+  is an OpenRouter-style model-routing id. A capability provider id
+  (`mineru`) names a *service*, not a model.
+- Coupling capability credentials into the model-provider table would force
+  every capability's auth shape through `ProviderSecretPayloadV1` and every
+  readiness probe through `probeOpenRouterCredential`.
+
+The Feishu Application Connection (`OrganizationFeishuApplicationConnection`)
+is the right structural precedent: it reuses the ADR-0024 envelope (KEK →
+DEK → AES-256-GCM, AAD-bound to purpose/org/connection/version) but has its
+own connection table, its own payload schema, its own readiness probe, and
+its own per-org uniqueness. Capability connections follow the same pattern.
+
+## Decision
+
+### External Capability
+
+An **External Capability** is a platform-registered, org-enabled document or
+media transform service invoked as a side effect of an `AgentRun`. It is
+identified by a stable `capabilityId` (e.g. `pdf_to_md_bundle`,
+`audio_video_to_text`). A capability:
+
+- Has an **input kind** (PDF, image, audio, video, …) and an **output
+  contract** (markdown bundle with extracted images, transcript text, …).
+- Bills in **non-token units** (pages, audio-seconds) recorded on a
+  `UsageFact` with `kind = external_capability`, or in tokens when the
+  backing service reports them.
+- Writes its output **into the invoking run's workspace** (ADR-0018
+  `AgentSurface` — no escapes).
+- Is invoked through a **capability adapter** in Hub, never by the Agent
+  shelling out with embedded credentials.
+
+### Capability Connection
+
+Credentials for a capability live in an **`OrganizationCapabilityConnection`**,
+structurally identical to the Feishu Application Connection:
+
+- Belongs to exactly one Organization.
+- Unique by `(organizationId, capabilityId)`.
+- `DRAFT` / `ACTIVE` / `DISABLED`; resolution accepts only `ACTIVE` with a
+  valid active secret version.
+- Secret material is an immutable, AAD-bound, KEK-wrapped envelope version
+  (`CapabilityCredentialVersion`), reusing the ADR-0024 encryption
+  machinery with `purpose = "capability"`.
+- Its payload schema is capability-specific (`CapabilitySecretPayloadV1`:
+  `baseUrl`, `apiToken`, optional `projectId`). New capability types extend
+  the payload, not the connection table.
+- A capability-specific **readiness probe** validates the credential before
+  activation (e.g. MinerU: a trivial authenticated GET). The probe is
+  injectable, matching the Feishu/provider pattern, so tests never hit the
+  network.
+
+### Capability Adapter
+
+The adapter is the seam between the Agent and the external service. It:
+
+- Resolves the org's active capability connection (fail-closed, no
+  process-global fallback — ADR-0024).
+- Accepts a workspace-relative input path and an output directory.
+- Calls the backing service (MinerU, Whisper, …) via an injectable
+  `Client` interface so the real HTTP client is swappable and mockable.
+- Writes the produced markdown + image assets into the run's workspace.
+- Writes one `UsageFact` (or more, if the service reports per-stage
+  consumption) with `kind = external_capability`, `capabilityId`,
+  `provider` (the service id), `quantity + unit` (pages / seconds), and
+  `costUsd + costSource = provider_reported` when the service reports cost.
+
+### Registry
+
+The platform maintains a **registry** of known capabilities: their id,
+input kind, output contract, metering unit, and adapter. This is
+code-level registration (like `ToolRegistry`), not a database table — a
+capability is available to an Organization only when (a) the platform
+knows the adapter and (b) the Organization has an `ACTIVE` connection for
+it. Both gates are required.
+
+### What is NOT in this ADR
+
+- The capability invocation is **not** a first-class persisted record
+  (`CapabilityInvocation` table) in this ADR. The `UsageFact` row with
+  `capabilityId` + `correlationId` is the durable trace. If we later need
+  a richer invocation log (retries, partial output, multi-stage status),
+  that is a follow-up; for now the fact is enough.
+- **Pricebook** remains deferred (ADR-0026). Capability facts use
+  `provider_reported` when the service returns cost; otherwise `unknown`.
+- **Org-scoped enable/disable policy** beyond connection status is
+  deferred. An org with an `ACTIVE` connection has the capability; one
+  without does not. A finer "enabled but no credential" toggle is not
+  needed yet.
+- **Agent-facing tool exposure** (how the Agent discovers and calls the
+  capability — MCP tool, Bash wrapper, or built-in) is an implementation
+  detail of the adapter wiring, not a contract concern. The contract pins
+  that the Agent never receives the capability credential.
+
+## Consequences
+
+- Adding a new external capability (e.g. `image_ocr`) is: register an
+  adapter, add a `capabilityId` constant, optionally extend the secret
+  payload — no schema change to `UsageFact` or `AgentRun`.
+- The model-provider connection table stays focused on model routing;
+  capability credentials do not pollute its payload or readiness probe.
+- Three connection types now share the ADR-0024 envelope: model-provider,
+  Feishu application, and capability. Each has its own table, payload
+  schema, and probe, but the same encryption, rotation, and resolver
+  boundary.
+- The Agent's Bash tool remains available, but the intended path for
+  document/media transforms is the capability adapter. Whether to narrow
+  Bash for capability-shaped tasks is an operational policy decision,
+  not a contract one.
+- Tests prove: workspace containment of capability output, fail-closed
+  credential resolution, `UsageFact` attribution with non-token metering,
+  and that the Agent process never receives the capability credential.
+
+## Deferred
+
+- `CapabilityInvocation` as a first-class durable record (status, retries,
+  partial output) — currently the `UsageFact` row is the only trace.
+- Pricebook derivation for capability costs (ADR-0026 deferred).
+- Org-scoped capability enable/disable policy finer than connection status.
+- Agent-facing tool discovery (MCP vs built-in) for capabilities.

+description: >
+  Convert PDF documents to Markdown bundles using the convert_pdf_to_md tool.
+  Handles PDFs from Feishu messages, local workspace files, and produces
+  high-quality Markdown with LaTeX formulas and extracted images.
+---
+
+# PDF to Markdown Conversion
+
+## When to use
+
+Use this skill when the user asks to convert a PDF to Markdown, extract text
+from a PDF, or turn a PDF document into an editable format.
+
+## How it works
+
+The `convert_pdf_to_md` tool (provided by the `cph_hub` MCP server) calls
+Alibaba Cloud Document Mind to parse the PDF. It:
+
+- Extracts text in reading order (handles multi-column, scanned, and
+  multi-language documents)
+- Converts mathematical formulas to **LaTeX** (`$...$` inline, `$$...$$` block)
+- Extracts tables as Markdown tables
+- Downloads embedded images into the output directory
+- Writes a single `document.md` file plus image files
+
+## Workflow
+
+### PDF from a Feishu message
+
+1. Use `feishu_read_context` to find the `file_key` of the PDF attachment.
+2. Use `feishu_download_resource` to download it into the workspace.
+3. Use `convert_pdf_to_md` with the downloaded file path and an output directory.
+
+### PDF already in the workspace
+
+1. Use `convert_pdf_to_md` directly with the file path and an output directory.
+
+## Important rules
+
+- **Always** use `convert_pdf_to_md` for PDF→Markdown. Do NOT attempt to parse
+  PDFs yourself with Read, Bash, Python, or any other method. The tool provides
+  accurate formula, table, and image extraction that manual methods cannot
+  match.
+- If `convert_pdf_to_md` fails because no capability connection is configured,
+  tell the user to ask their organization admin to configure the Aliyun
+  docmind credential in the admin web UI (组织后台 → 能力).
+- The output directory will be created if it does not exist.
+- After conversion, use `send_file` to send the generated markdown back to the
+  user if they requested it.
+
+## Output
+
+The tool returns a list of generated files:
+- `document.md` — the main markdown file
+- `*.jpg` / `*.png` — extracted images, referenced from the markdown
+
+## Cost
+
+The conversion is billed per page (0.04 CNY/page ≈ $0.0056/page for the
+enhanced formula mode). The cost is automatically recorded on the run's
+usage ledger.

+`/database/*` HTTP 面。代码写在这个目录里，`hub.ts` 通过 `plugin.ts` 挂载它，
+所以服务器启动时能正确识别这些路由。
+
+页面：
+
+- `/database/admin` —— 飞书登录页（唯一登录方式）
+- `/database/dashboard` —— 左菜单 + 右内容的后台，未登录会跳回 `/database/admin`
+
+登录走平台既有的飞书 OAuth：登录页的按钮指向 `/auth/feishu/<orgSlug>`，
+回调由 `src/admin/routes/authRoutes.ts` 处理并种下 session cookie。
+
+## 开发模式：用环境变量开启一键登录
+
+本地开发没有真实飞书 app 时，可以用环境变量开启一键登录，跳过飞书 OAuth，
+直接以现有 OWNER/ADMIN 身份登入后台。**仅限开发，不是生产登录路径。**
+
+### 怎么开
+
+在 `hub/.env` 里设：
+
+```sh
+HUB_DEV_LOGIN_BYPASS="true"
+```
+
+改完重启服务（`npm run dev`，或本地手动 `npx tsx src/server.ts`）。启动日志会
+打印一行 `DEV login bypass enabled: /database/dev-login ...` 作为确认。
+
+开启后：
+
+- `/database/admin` 登录页显示「⚡ 一键登录管理员」按钮
+- 后端注册 `/database/dev-login` 端点：按钮就是打它，它签发一个和飞书 OAuth
+  回调完全一样的 session，然后跳到 `/database/dashboard`
+
+### 怎么关
+
+把值设成 `false`（或 `0` / `no` / `off`），或删掉这一行。关闭后按钮消失、
+`/database/dev-login` 返回 404 —— 按钮和端点同进同退。
+
+### 双重门禁（重要）
+
+真正的开关是两个条件的**与**（判断在 `plugin.ts`）：
+
+```
+allowDevLoginBypass = (NODE_ENV !== "production") && HUB_DEV_LOGIN_BYPASS 为真
+```
+
+即：**只要 `NODE_ENV=production`，无论 `HUB_DEV_LOGIN_BYPASS` 设成什么，一键登录
+都强制关闭。** 生产始终只能走真实飞书 OAuth。
+
+> 提醒：`HUB_DEV_LOGIN_BYPASS` 是敏感开关，别把开着它的 `.env` 带到任何联网 /
+> 共享环境。整个旁路逻辑自包含在本目录（`plugin.ts` + `routes/databaseRoutes.ts`），
+> `src/admin` 的登录路由未受影响。

+
+关键语义速查:
+
+- **D8**:无权限 → 404(不泄露存在性);越权 → 403;Group 服务故障 → 503
+- **D11**:creator 不可变 + 自动 MANAGE;独立权限关闭时项目级非创建者 grant 冻结
+- **D12**:move = 本节点 MANAGE + 目标父 EDIT+,事务 + pg 咨询锁
+- **D15**:删除只打标本节点,"任一祖先已删"即整支不可见
+- **8.1**:MANAGE 仅创建者可授/收;creator grant 不可动
+- **审计**:一切写操作在业务事务内写 AuditEntry(同事务,失败即回滚);
+  文件内容写先 versionStore.commit 再审计(宁多版本,不造假审计)
+
+## 约定（与 admin 面一致）
+
+1. 路由用**绝对路径** `"/database/..."`，不用 Fastify prefix —— 每条路由 grep 得到。
+2. **guard 前置、fail closed**：凡碰数据的端点第一行先跑
+   `requireSession` / `requireOrgRole` / `requireProjectPermission`
+   （都在 `../admin/auth/guards.js`）。
+3. **租户隔离**（ADR-0020）：每个 Prisma 查询都 scope 到 `auth.organization.id`，
+   不得跨 org。禁止无鉴权的数据路由。
+4. 数据库通过传入的 `config.prisma` 访问（全进程单例，见 `../db.ts`）；
+   不要在这里 `new PrismaClient()`。
+
+## 为什么代码在 `src/` 下
+
+`tsconfig.json` 固定 `rootDir: "src"` 且 `include: ["src/**/*.ts"]`。只有
+`src/` 下的 `.ts` 会被 `tsc` 编译、被 `tsx watch`（`npm run dev`）加载。放在
+`src/` 之外的目录不会被构建，外部识别不到。
