+# 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.

+# ADR 0028: Agent Configuration Folder Tree
+
+## Status
+
+Accepted.
+
+## Context
+
+ADR-0017/0018 made Agent roles and skills Organization-scoped dynamic runtime
+configuration, managed without process restarts. The org admin surfaces for
+them (`/admin/roles` and `/admin/skills`) render every
+role/skill as one large editor card in a single flat list. As an Organization
+accumulates roles and skills, the management pages degrade into an endless
+scroll with no grouping affordance.
+
+The project explorer already solves the analogous problem for projects with
+transparent folders (ADR-0021): org-scoped navigation nodes that are not
+permission resources. Roles and skills need the same affordance, but their
+semantics differ from projects in one crucial way: skill names and role IDs
+are referenced by role→skill bindings, run-time skill snapshot loading, and
+Feishu slash commands. Any grouping mechanism must not leak into those
+resolution paths.
+
+## Decision
+
+Introduce an Organization-scoped folder tree shared by Agent roles and Agent
+skills:
+
+- One folder tree per Organization is shared by both roles and skills (e.g. a
+  "高三化学组" folder groups that team's roles and its skills together). It is
+  a distinct entity from the project explorer `Folder` of ADR-0021 — the two
+  trees are managed independently and never reference each other.
+- Folders are **transparent organization nodes**, following the ADR-0021
+  project-folder precedent: they exist for management-surface navigation and
+  grouping only, are not permission resources, and hold no grants.
+- Folder membership is **not part of role/skill identity or resolution**:
+  - skill `name` and role `roleId` remain unique per Organization regardless
+    of folder membership;
+  - role→skill bindings, run admission's frozen role snapshot, run-scoped
+    skill loading, and Feishu slash commands never reference folders.
+- Each role/skill sits in at most one folder; membership is optional
+  (unfiled items remain first-class). Folders nest arbitrarily.
+- Folder assignment is a label-class change in the ADR-0017 sense: it never
+  archives Agent sessions, because the execution surface (model, prompt,
+  tools, skill content) is untouched.
+- A folder can be deleted only when empty — no child folders, no roles, no
+  skills. Relocating items out of a folder is an explicit user action, so no
+  orphan-placement rule is needed yet.
+- Admin web renders both pages as a left folder tree plus the item list of
+  the selected folder ("all" and "unfiled" included). The host-console CLI is
+  unchanged: folder management lives in the web surface, and CLI
+  `upsert-role`/`install-skill` never touch folder assignment.
+
+## Consequences
+
+- New DB entity `OrganizationAgentConfigFolder` (org-scoped, self-nesting via
+  `parentId`, delete restricted while referenced) plus nullable `folderId` on
+  `OrganizationAgentRole` and `OrganizationAgentSkill` (SetNull on folder
+  delete, though the service refuses to delete non-empty folders).
+- The spec pins the transparency and single-membership semantics in
+  `Spec.System.AgentRole` (`AgentConfigFolder`), so future implementors do
+  not re-derive them differently (e.g. path-style names or per-folder
+  uniqueness).
+- Org admin APIs gain folder CRUD plus role/skill folder-assignment endpoints
+  that skip session archival by construction.
+- Moving a role/skill between folders changes nothing about authorization,
+  run resolution, or audit-visible configuration lineage beyond the folder
+  assignment event itself.
+
+## Open Questions / Deferred
+
+- Drag-and-drop assignment and bulk moves are deferred; assignment is a
+  per-item select for now.
+- Folder-level usage aggregation for roles/skills is deferred (project
+  folders already aggregate usage under ADR-0021; agent configuration has no
+  usage dimension yet).
+- CLI flags for folder assignment are deferred until a console workflow asks
+  for them.
+- Folder-scoped default-role policies (e.g. per-folder defaults) are rejected
+  for now: the Organization keeps exactly one active default role
+  (ADR-0017/0018 invariant) regardless of folder structure.

+  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.

+/**
+ * Org-admin Agent configuration routes (ADR-0017 / ADR-0018).

+ * pipeline and one set of safety checks (SKILL.md manifest required, 512-file
+ * / 16-byte limits, symlink rejection).
+ *
+ * Folder tree (ADR-0028): one org-scoped transparent folder tree shared by
+ * roles and skills for management-surface grouping. Folder endpoints never
+ * touch session state — assignment is a label-class change (ADR-0017).

+# Capability —— 外部能力注册与调用(ADR-0027)
+
+`AgentRun` 内可能调用**外部能力**:PDF→MD bundle、音视频→文本、OCR 等。这些能力
+不是主 agent loop 的模型 completion,不持项目锁,不占 session 语义(ADR-0026 已拒绝
+nested Run)。它们是 Run 内的副作用:读 workspace 输入、调外部服务、产物落 workspace、
+写一条 `UsageFact`。
+
+本模块 pin 三件事:
+
+1. **ExternalCapability** —— 平台注册的、org 启用的文档/媒体转换服务,由稳定
+   `capabilityId` 标识。
+2. **CapabilityConnection** —— org-scoped 凭证连接,复用 ADR-0024 信封机制但独立于
+   model-provider connection。只有 `active` connection 可被 resolver 使用。
+3. **CapabilityInvocation 良构** —— 调用的输入/输出必须落在 run 的 workspace 内
+   (ADR-0018 `AgentSurface`),且调用产生的消耗必须以 `UsageFact` 记录。
+
+凭证不经 Agent 子进程:Agent 只通过 capability adapter 间接调用,adapter 在 Hub 侧
+解析 org-scoped 凭证并调用外部服务(ADR-0024 resolver boundary)。这与 model-provider
+的 loopback proxy 是不同的机制——capability 调用不走 agent 的网络面,走 Hub 直连。
+
+不变式(`PINNED`, ADR-0027):
+
+- **凭证隔离** —— capability credential 不进 Agent 进程环境;adapter 在 Hub 侧解析。
+- **workspace 边界** —— 输入路径与输出目录都必须落在 run 的 workspace 内(ADR-0018)。
+- **必记 fact** —— 一次成功调用必须产生 ≥1 条 `UsageFact`(`kind = externalCapability`),
+  即使 `costUsd = none`(unknown ≠ 零,ADR-0022/0026)。
+
+`CapabilityInvocation` 作为一等持久记录(status/retries/partial output)在 pilot 不做;
+`UsageFact` 的 `capabilityId + correlationId` 是唯一可追溯痕迹(ADR-0027 Deferred)。

+# Usage —— Run 内用量计量事实账本(ADR-0026)
+
+一次 `AgentRun` 内可能产生**多条**可计费消耗:主模型 completion、外部能力调用
+(PDF→MD bundle、音视频转写等)、或代理网关侧旁路调用。这些消耗**不**是子 Run——
+它们不持项目锁、不占 session 语义、不复用 `AgentRun` 状态机。它们是 Run 内的
+append-only **计量事实**(`UsageFact`)。
+
+`AgentRun` 上的 cost/token 标量是 facts 的派生 rollup cache,不是真相来源;真相在
+`UsageFact` 行。这一层抽象让"主模型"与"外部能力"两类消耗共享同一账本,而非给后者
+各开一种特化字段或 nested Run。
+
+核心不变式(`PINNED`, ADR-0022 + ADR-0026):
+
+- **append-only** —— fact 一旦写入只读不更不删;`costUsd` 修正走新 fact,不改旧行。
+- **`costUsd = none` 表示"未知",不是"零成本"** —— ADR-0022:missing provider cost
+  remains unknown rather than zero。聚合时不得把 none 当 0 求和。
+- **fact 不持锁、不跨 run** —— 它是 Run 内的副作用账本,不是又一次 `@bot` 生命周期。
+  外部能力调用亦同:它的语义边界是 `capabilityId` + `correlationId`,不是 `RunId`。
+- **价目回算是派生** —— `costSource = pricebookDerived` 时,`costUsd` 由
+  `occurredAt × (provider, model)` 查价目表派生;provider 实报(`providerReported`)
+  优先于派生。无价目可查时 `costSource = unknown`,`costUsd = none`。
+
+外部能力(capability)注册表、价目表(pricebook)、商业结算均 `OPEN`,pilot 不做
+(ADR-0021 仍 defer commercial billing)。本模块只 pin **账本结构与不变式**。
