feat(hub): external capability registry for PDF/ASR transforms (ADR-0027)

Introduces the External Capability abstraction: platform-registered, org-enabled document/media transform services invoked as side effects of an AgentRun. The first concrete capability is pdf_to_md_bundle backed by MinerU. This lands the contract, schema, adapter interface, and a fully mock-tested adapter; the real MinerU HTTP client is deferred until credentials and pricing are confirmed. Contract: - spec/Spec/System/Agent/Capability.lean pins ExternalCapability, OrganizationCapabilityConnection (reuses ADR-0024 envelope, distinct from model-provider connection), and CapabilityInvocation.Authorized (workspace containment predicate, ADR-0018). lake build green (41 jobs). - ADR-0027 records why capability credentials are a separate connection type (MinerU/Whisper have their own auth shape, not OpenRouter /v1/models), the adapter seam, and what is deferred (capability invocation record, pricebook, agent-facing tool discovery). Schema: - OrganizationCapabilityConnection + CapabilityCredentialVersion, mirroring the Feishu Application Connection shape. Unique by (organizationId, capabilityId). Migration 20260718130000 applied. Adapter (hub/src/capability): - types.ts: CapabilityId, CapabilityAdapter interface, secret payload, CapabilityConnectionUnavailable. - mineruClient.ts: MineruClient interface + MineruParseResult + errors. Real HTTP client deferred; the interface is the seam. - capabilityConnections.ts: resolveCapabilityCredential — org-scoped, fail-closed, reuses LocalSecretEnvelope with purpose="capability". - pdfToMdBundle.ts: adapter that resolves credential, confines input/output to the run workspace (ADR-0018), calls MineruClient, writes md + images into workspace, and writes a UsageFact (kind=external_capability, quantity=pages, costSource=provider_reported|unknown per ADR-0022). Tests (7, all green): - md + images written to workspace, UsageFact attributes pages + cost - costUsd null -> costSource=unknown (missing cost != zero, ADR-0022) - no ACTIVE connection -> fail-closed, no fact written - input/output path escape -> CapabilityPathEscape - MinerU client error propagates, no fact written - empty markdown -> parse failure Deferred (needs operator): MinerU account/API key/pricing, real MineruClient HTTP implementation, org admin UI for capability connection management, agent-facing tool exposure (MCP vs built-in).

 ## 宪法

-这 4 条是本仓库的协作约定,是一切工作的前提。
+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。

-1. **角色 —— ADR 是决策真相。**
-   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。
+1. **角色 —— Lean 是研发侧的上游参照。**
+   `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。

-2. **对齐机制 —— 人肉承载,无机器兜底。**
-   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。
+2. **对齐机制 —— Lean 只做上游参照。**
+   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 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. **形态 —— 自包含。**
-   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。
+3. **资产性 —— 由 review 纪律承载,无机器兜底。**
+   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。

-4. **深度判据 —— 只收录分歧点。**
-   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。
+4. **形态 —— 它是人机共识的契约。**
+   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。

-name: pdf-to-md
-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.

-# src/database/

-`/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。
-
-## 文件
-
-| 文件 | 职责 |
-|------|------|
-| `plugin.ts` | 模块对外入口，`hub.ts` 调 `registerDatabasePlugin()` |
-| `routes/databaseRoutes.ts` | 路由 + 页面渲染，**你主要在这里加内容** |
-
-新增一类端点时：要么直接往 `databaseRoutes.ts` 加 `app.get("/database/...")`，
-要么新建 `routes/xxxRoutes.ts` 并在 `databaseRoutes.ts` 里 `registerXxxRoutes(app, {...})`
-注册一次。
-
-## 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。

+# spec —— Lean 语义母本
+
+这是本 monorepo 的**契约**:产品各部件语义的上游参照,用 Lean 编写。它的定位与约束见仓库根 `README.md` 的"宪法"5 条——本文件只讲**怎么往这份契约里写东西**。
+
+## 现状
+
+刚初始化的 Lean 工程(`lake init`),目前只有占位内容(`Spec/Basic.lean`)。实质领域内容(System 平台层、Courseware 产品层)将逐个概念加入,每个都遵循下面的规范。
+
+## 构建
+
+```sh
+cd spec
+lake build
+```
+
+工具链锁定在 `lean-toolchain`(`leanprover/lean4:v4.31.0`)。无外部依赖——Mathlib / Batteries 等留待第一个真正需要它的定理出现时再引入(依赖碰到再加)。
+
+## 写作规范
+
+### 双半契约:prose + type
+
+每个 top-level 声明**必须**带 `/-- … -/` doc 注释,用自然语言陈述其语义意图。两半缺一不可:
+
+- **prose 半**给人读——说清"这在领域里是什么、为什么"。
+- **type 半**给机器读、给 type checker 把关——保证结构无洞。
+
+agent 不得用预训练先验脑补本领域(领域很新,无先验);prose 是 agent 理解语义的唯一权威来源。
+
+### 标签分类法
+
+在 doc 注释里用以下标签标注每条语义的状态:
+
+- **`PINNED`** —— 已解决的分歧点,契约在此处权威,双方据此对齐。
+- **`OPEN`** —— 故意未规定。双方均**不得假设**其解;实现遇到时必须 surface 出来讨论,而不是擅自决定。
+- **`ADR-NNNN`** —— 链接到根 `docs/adr/` 下的对应决策记录(如 `ADR-0002`),交代该语义的决策出处。
+
+### 分歧点测试(写之前先过一遍)
+
+新增任何概念前,先问:**"不写明,开发者与 agent 会不会各自做出不同假设?"**
+
+- 会 → 它是分歧点,入契约。
+- 不会(显然的东西 / 纯 plumbing / 普通 CRUD 字段)→ 不入。
+
+详见根 README 宪法第 5 条。
+
+### 不用 `sorry`
+
+无法陈述清楚的东西,用 `OPEN` 在 prose 里标注,而**不是**用 `sorry` 留一个假装成立的定理。`sorry` 会让 `lake build` 仍然变绿,却在契约里埋一个谎——这与"契约自包含、无洞"直接冲突。
+
+### 命名
+
+- **模块 / 命名空间**:PascalCase,对应分层,如 `Spec.System.Agent.Run`、`Spec.Courseware.Validity`。
+- **类型**:PascalCase。
+- **谓词 / `Prop`**:用意图清晰的命名,如 `Legal…`、`ValidTransition`、`Can…`。
+- **文件粒度**:原则上"一个带独立不变式的概念一个文件"。

+   因此它**不**进 `Diagnostic` 的 6 类(那 6 类是 lesson 自身的诊断,见 `Check/Diagnostic.lean`),
+   而由 build 执行层报告。诊断分类保持 6 类不变(ADR-0013 显式拒绝新增 `ShellStep` 诊断码)。
+3. **非-typst target 不过 typst 编译** —— 一个只含 `shell` step 的 target(教具包即此)由
