 ## 画板优先规则

 写文档时，重要信息优先画板化。遇到核心流程、系统架构、方案对比、风险链路、里程碑、指标趋势、因果归因、组织关系、能力分层等内容，不要只用段落或表格承载；除非内容只是一次性补充说明，否则应规划为画板。

-同一篇文档可以有多个画板。优先多个聚焦画板，而不是把所有信息塞进一张大图。

-简单图判定：节点少、静态、布局可控、适合一个完整自包含 SVG 表达，例如小型流程、2-3 方对比、小型状态机、简单时间线或小型示意图。
+> [!IMPORTANT]
+> ⚠️ **分别对每个图表进行决策**

-复杂图判定：节点多、跨泳道/跨系统、需要自动布局或精细排版、包含数据图表、组织架构、复杂架构、复杂依赖、已有画板更新，或需要 `lark-whiteboard` 的渲染验证。
+如果有多个位置需要插入图表，你需要根据每个图表的内容**分别决定**采用步骤 2A 还是 2B
+中的方式插入这个图表。在需要插入思维导图、时序图、类图、饼图、甘特图的时候可以插入 mermaid 块，在需要插入其他类型图表时启动
+SubAgent 插入 SVG。

-### 步骤 2A：简单图 — SubAgent 直接插入 SVG 画板
+建议优先使用 SVG 插入图表，除非其属于思维导图、时序图、类图、饼图、甘特图这类可以直接使用 mermaid 语法描述，且不适宜用 SVG 绘制的图表
+
+### 步骤 2A: 使用 mermaid 插入图表
+
+```xml
+
+<whiteboard type="mermaid">
+    mermaid 代码...
+</whiteboard>
+```
+
+### 步骤 2B: SubAgent 使用 SVG 插入图表

 主 Agent 启动 SubAgent，让它用 `docs +create --api-version v2` / `docs +update --api-version v2` 插入：

 ```xml
-<whiteboard type="svg"><svg ...>...</svg></whiteboard>
+
+<whiteboard type="svg">
+    <svg...>...
+    </svg>
+</whiteboard>
 ```

-简单图 SubAgent 的最小上下文：
+Sub Agent 需要携带以下的最小上下文，以及后续的 [SVG 设计 Workflow] 章节指南：
+
 - doc token、插入位置（标题 / block_id / command）
 - 图表目标、受众、源段落或数据
 - 要求读取 `lark-doc-xml.md`；不需要读取 `lark-whiteboard`
 - SVG 必须完整自包含：包含 `<svg>` 根节点和 `viewBox`，不引用外部图片、脚本、远程资源

-### 步骤 2B：复杂图 — 先创建空白画板
+#### 画板 SVG 设计指南

- 主 Agent 使用 `docs +create --api-version v2` / `docs +update --api-version v2` 插入 `<whiteboard type="blank"></whiteboard>`。
- 从 v2 响应的 `data.document.new_blocks[]` 中读取 `block_type == "whiteboard"` 的 `block_token` 作为 board_token。

-### 步骤 3B：复杂图或已有画板 — 启动 lark-whiteboard SubAgent
+- 大多数 AI 如果只考虑“绝对不报错/完美映射”, 最终给出的都是全篇纯白底色加单层 `<rect>` 的方正卡片网格, 极其死板单调, *
+  *这将被视为不及格！**
+- **SVG 给你了完全的设计自由**, 请大胆使用你脑内的图标路径 (`<path>`), 连接指引 (`流畅的 <path>`), 各种环境氛围点缀,
+  大胆一点, 充分信任你的品味, 发挥出你的顶级艺术创造力！
+
+##### SVG 设计 Workflow
+
+###### 1. 想清楚要画什么
+
+- **核心信息是什么？** 能做到一图胜千言, 绝对不要只生成平平无奇的文字表格, 要有设计感
+- **内容充实度**：如果用户描述稀疏简略, 利用你的领域知识扩展, 保证信息维度和内容充实, 但不要过度堆砌, 淹没重点
+- **视觉层级与隐喻**：这个没有固定的形式, 你自由判断, 比如: 给重要的节点加光环, 加高亮背景；给对比项设计天平或对称结构
+
+###### 2. 写 SVG
+
+> [!IMPORTANT]
+> 布局, 配色, 信息密度, 装饰物——**全部由你判断**, 打破单调的 `<rect>` 牢笼, 严禁通篇用矩形和文字应付用户
+> 操作边界约束：
+
+- **语言跟随用户**：图表文字的语言与用户 prompt 保持一致, 技术术语用行业里通用的写法, 不机械翻译
+- 文字用 `<text>`(不是 `<path>`), 容器宽度留够——画板按 CJK ≈ 1em / Latin ≈ 0.6em 重排
+- 连线使用正交折线替代斜直线(`<polyline>` 带水平/垂直折点)视觉效果更好
+- 可自由使用 `translate`, `rotate`, `scale`但请尽量避免使用 `skewX` / `skewY` / `matrix(...)` 发生空间级扭曲
+
+###### 画板怎么处理 SVG
+
+画板的 svg-parser 把可识别元素转成可编辑节点, 其余降级为内嵌图片(渲染没问题, 虽然不可编辑, 但是可以正常显示)；但
+`<radialGradient>` / `<filter>` / `<clipPath>` 等装饰特性画板完全不支持，会导致渲染问题（见下方⚠️）
+**不需要所有元素都可编辑, 但必须避免使用不支持的装饰特性, 且要兼顾可编辑和美观漂亮**
+
+**可识别的元素**
+
+- 形状：`<rect>` / `<circle>` / `<ellipse>` / `<polygon>`
+- 连线：`<line>` / `<polyline>` / `<path>`(自动识别为直线 / 折线 / 曲线)
+- 文本：`<text>` / `<tspan>` 画板硬编码 Noto Sans SC **文字必须用 `<text>`**
+- 分组：`<g>` / `<a>` / `<use>` 引用 `<symbol>`
+- 变换：`translate` / `rotate` / `scale` 正常；`skewX` / `skewY` / `matrix(...)` 降级
+
+> [!IMPORTANT]
+> ⚠️ ** 不支持的装饰特性**
+
+- `<radialGradient>` / `<filter>` / `<pattern>` / `<clipPath>` / `<mask>` → 画板都不支持，**请避免使用，否则会导致画板渲染问题
+  **
+
+###### 3.插入后审查
+
+插入画板后，可以从返回值使用 lark-cli 指令，将画板内容导出为 png
+图片。若是对设计不满意，可以修改后，删除原来的画板再重新插入，或是调用 [
+`../../lark-whiteboard/SKILL.md`](../../lark-whiteboard/SKILL.md) 编辑。
+
+```bash
+lark-cli whiteboard +query \
+  --whiteboard-token "wbcnxxxxxxxx" \
+  --output_as image \
+  --output ./preview.png
+```
+
+### 步骤 3B：编辑已有画板 — 启动 lark-whiteboard SubAgent

 复杂图和已有画板更新必须启动 SubAgent。主 Agent 只传最小上下文，不直接执行 `lark-whiteboard` 的渲染和写入流程。

 - 与图表直接相关的源段落或数据

 ### 步骤 4：完成校验

- 简单 SVG：确认插入的是 `<whiteboard type="svg">`，且内容是完整 `<svg ...>...</svg>`
- 复杂画板：确认每个 token 对应的画板都已填充真实内容
+- Mermaid: 确认插入的是 `<whiteboard type="mermaid">`，且内容 mermaid 语法完整
+- SVG: 确认插入的是 `<whiteboard type="svg">`，且内容是完整 `<svg ...>...</svg>`
 - 不保留空白占位画板；复杂路径只有空白画板而无内容视为任务未完成

+# drive +secure-label-list / +secure-label-update（云文档密级标签）
+
+## 何时使用
+
+- `drive +secure-label-list`：查询当前用户可用的密级标签，先拿到目标 `id`。
+- `drive +secure-label-update`：把目标云文档调整为指定密级标签。
+
+这两个 shortcut 都使用用户身份（`--as user`）。修改密级前，通常先执行 `+secure-label-list` 确认可用标签 ID。
+
+## 查询可用密级标签
+
+```bash
+lark-cli drive +secure-label-list --page-size 10 --lang zh
+```
+
+可选参数：
+
+| 参数 | 说明 |
+|------|------|
+| `--page-size` | 分页大小，范围 `1..10`，默认 `10` |
+| `--page-token` | 上一页响应里的 `page_token` |
+| `--lang` | 标签语言：`zh`、`en`、`ja` |
+
+底层接口：`GET /open-apis/drive/v2/my_secure_labels`。
+
+## 修改文档密级
+
+```bash
+lark-cli drive +secure-label-update \
+  --token "https://example.feishu.cn/docx/doxcnxxxx" \
+  --label-id "7217780879644737539"
+```
+
+参数：
+
+| 参数 | 说明 |
+|------|------|
+| `--token` | 目标文档 URL 或 bare token；URL 可自动推断 `--type` |
+| `--type` | bare token 必填；URL 输入时可省略。可选：`doc`、`docx`、`sheet`、`file`、`bitable`、`mindnote`、`slides` |
+| `--label-id` | 要设置的密级标签 ID |
+
+底层接口：`PATCH /open-apis/drive/v2/files/:file_token/secure_label`，query 参数 `type`，请求体 `{ "id": "<label-id>" }`。
+
+## 错误处理
+
+CLI 不会在 shortcut 中为密级错误码追加专用 hint；agent 必须根据返回的 `error.code` 做以下引导。
+
+| 错误码 | 含义 | 引导 |
+|--------|------|------|
+| `1063013` | 密级降级需要审批 | 提示用户打开目标文档，在文档界面完成密级降级审批后重试；如果用户传入的是文档 URL，必须把该 URL 一并给用户作为操作入口 |
+
+遇到 `1063013` 时，不要继续重试 API，也不要提示补 scope；这是文档侧审批流程要求，需要用户到文档里操作。

+# Minutes Events
+
+> **Prerequisite:** Read [`../SKILL.md`](../SKILL.md) first for the `event consume` essentials (commands, subprocess contract, jq usage).
+
+## Key catalog (1)
+
+| EventKey | Purpose |
+|---|---|
+| `minutes.minute.generated_v1` | A minute (妙记) has been generated |
+
+This key uses a **Custom schema** (flat output at `.xxx`) and carries a **PreConsume hook** that auto-subscribes / unsubscribes via OAPI on first / last consumer.
+
+## Scopes & auth
+
+| EventKey | Scope | Auth |
+|---|---|---|
+| `minutes.minute.generated_v1` | `minutes:minutes.basic:read` | user |
+
+Requires `--as user`.
+
+## `minutes.minute.generated_v1`
+
+### Output fields
+
+| Field | Type | Description |
+|---|---|---|
+| `type` | string | Event type; always `minutes.minute.generated_v1` |
+| `event_id` | string | Globally unique event ID; safe for deduplication |
+| `timestamp` | string (timestamp_ms) | Event delivery time (ms timestamp string) |
+| `minute_token` | string | Minute token |
+| `title` | string | Minute title (enriched via detail API) |
+| `minute_source` | object | Minute source metadata; only present when the source is a meeting |
+| `minute_source.source_type` | string | Source type; only present when the source is a meeting (value: `meeting`) |
+| `minute_source.source_entity_id` | string | Source entity ID (meeting ID); only present when the source is a meeting |
+
+### Enrichment & degradation
+
+The Process hook calls `GET /open-apis/minutes/v1/minutes/{minute_token}` to enrich `title`. If the detail API fails, this field is left empty — the base fields (`type`, `event_id`, `timestamp`, `minute_token`, `minute_source`) are always present.
+
+`minute_source` is populated from the event payload directly (not the detail API), so it survives enrichment failures. Note: `minute_source` is only present when the minute originates from a meeting; for other sources (e.g. recording, local upload) this field is absent.
+
+### Example
+
+```bash
+lark-cli event consume minutes.minute.generated_v1 --as user
+
+# Project title and token only (skip events where enrichment failed)
+lark-cli event consume minutes.minute.generated_v1 --as user \
+  --jq 'select(.title != "") | {minute_token, title}'
+
+# Filter by source type
+lark-cli event consume minutes.minute.generated_v1 --as user \
+  --jq 'select(.minute_source.source_type == "meeting") | {minute_token, title}'

+| `end_time` | string | Meeting end time in RFC3339, converted to the local timezone |
+| `calendar_event_id` | string | Calendar event ID associated with the meeting |
+
+### Gotchas
+
+- `start_time` / `end_time` are **not** the raw unix-seconds from OAPI — the Process hook converts them to local-timezone RFC3339. If the raw value is empty or non-numeric, the field is left empty.
+- No detail API call is made; all fields come from the event payload itself.
+
+### Example
+
+```bash
+lark-cli event consume vc.meeting.participant_meeting_ended_v1 --as user
+
+# Project meeting topic and end time only
+lark-cli event consume vc.meeting.participant_meeting_ended_v1 --as user \

sang-neo03	9e2be14301	feat(schema): output json spec envelope for all API commands (#1048 ) * feat(schema): add envelope types and ordered properties container * feat(schema): build meta_data.json key-order index for property ordering * feat(schema): implement convertProperty with file/enum/range/nested handling * feat(schema): build inputSchema with x-in / file binary / yes injection * feat(schema): build outputSchema wrapping responseBody * feat(schema): build _meta with scopes/risk/access_tokens normalization * feat(schema): scaffold affordance overlay loader (PR-1 stub) * feat(schema): wire up AssembleEnvelope main entry point * feat(schema): parse dotted and space-separated path arguments * feat(schema): batch envelope assembly with optional method filter * feat(schema): implement L1-L3 envelope lint (structure/type/cross-field) * feat(schema): measure L4 coverage and gate all envelopes through L1-L3 * feat(schema): add golden test harness with UPDATE_GOLDEN refresh * test(schema): seed 20 golden envelopes covering edge cases * feat(schema): output MCP envelope as default JSON, preserve pretty mode Rewrites cmd/schema/schema.go so the default --format json branch emits MCP-spec envelopes via schema.AssembleAll/AssembleService/AssembleEnvelope. The legacy --format pretty branch is preserved verbatim and still uses printServices / printResourceList / printMethodDetail. Args max raised from 1 to 8 so the path can be supplied either as a single dotted argument (im.reactions.list) or as space-separated segments (im reactions list); both forms route through schema.ParsePath and produce byte-identical output. The completeSchemaPath function is extended to drive tab-completion for both forms: legacy dotted prefix when len(args) == 0, and per-segment resource/method completion when args already contains earlier segments. BREAKING CHANGE: default JSON output shape changes from the raw meta_data structure to an MCP envelope array/object. Existing scripts parsing the old shape must either pin --format pretty or migrate to the new envelope fields (name, description, inputSchema, outputSchema, _meta). * test(schema): cover envelope JSON output, space-form path, yes injection Replaces TestSchemaCmd_NoArgs with two variants reflecting the new default shape: TestSchemaCmd_NoArgs_Pretty asserts the legacy "Available services" text appears only under --format pretty, and TestSchemaCmd_NoArgs_JSON_IsArray asserts the default JSON output parses as an envelope array with at least 180 entries. Adds six new tests: - TestSchemaCmd_JSONIsEnvelope: single-method output has name / description / inputSchema / outputSchema / _meta keys and envelope_version "1.0". - TestSchemaCmd_SpaceSeparatedPath_EqualsDotted: dotted and space forms produce identical output bytes for the same command path. - TestSchemaCmd_ServiceListIsArray: schema <service> returns a JSON array whose every entry's name starts with "<service> ". - TestSchemaCmd_HighRiskYesInjection: high-risk-write commands inject inputSchema.properties.yes. - TestSchemaCmd_NoYesForReadRisk: read-risk commands do not inject yes. - TestSchemaCmd_PrettyUnchanged_KeyTextPresent: --format pretty still surfaces the legacy section markers (Parameters:, Response:, Identity:, Scopes:, CLI:). * feat(schema): assemble envelope from embedded data only for stability * chore(schema): lint cleanup * fix(schema): preserve dotted resource segments in envelope name Nested resources whose meta_data key contains a dot (e.g. chat.members, user_mailbox.templates) were previously split on '.' and rejoined with spaces, producing envelope names like 'im chat members bots'. AI consumers doing name.split(' ') and feeding the result back as argv got 'lark-cli im chat members bots' which the CLI rejects — the actual invocation form is 'lark-cli im chat.members bots'. Pass the dotted resource key as a single argv segment so the envelope name 'im chat.members bots' round-trips through name.split(' ') back to the CLI. Mirror the same convention in the golden harness so its single-method assembly matches the live AssembleService walk. * fix(schema): align MCP envelope output with JSON Schema 2020-12 contract - coerce enum literals to typed JSON values (integer to int64, number to float64, boolean to bool) so type:"integer" fields no longer emit string enums; sort numeric/boolean enums while preserving meta_data order for string enums that carry semantic priority - translate non-standard meta_data type:"list" to JSON Schema type:"array" with items:{} fallback when element shape is absent (covers the two mail attachment_ids fields) - render inputSchema.required even when empty so consumers see a stable envelope shape ("[]" means no required fields, not "field is missing") - reject trailing path segments in both JSON and pretty modes so schema im.messages.delete.foo errors instead of silently returning the delete method - drop dead "list type" entry from lint_test isKnownDataInconsistency whitelist now that list values are translated upstream * fix(schema): address CodeRabbit findings and stabilize CI tests CI fix - Replace hard-coded absolute key-order assertions in TestKeyOrderIndex_* and TestBuildInputSchema_* with set-membership and propagation invariants; the upstream meta_data API does not guarantee stable JSON key order across fetches, so the old tests were flaky on CI by design. - Skip byte-level TestGoldenEnvelopes when CI=true; golden snapshots are a manual refresh artefact tied to a specific meta_data fetch, not a CI gate. - Add TestMain to isolate registry-backed tests from any host ~/.lark-cli cache (LARKSUITE_CLI_CONFIG_DIR + LARKSUITE_CLI_REMOTE_META=off) so the suite gives the same answer on every machine. CodeRabbit review actionables - EmbeddedServiceNames returns a defensive copy so callers cannot mutate the package-level slice and affect subsequent assembly determinism. - coerceEnumValue is now also applied to default literals: integer fields no longer ship default: "500" — they ship default: 500 (same idea as the earlier enum coercion fix). - options-branch string enums preserve meta_data source order, matching the enum-branch policy; only numeric/boolean enums get sorted. - validatePropertyTypes now validates the array element schema itself (type, nested items), not only items.properties — previously a primitive element with an invalid type (e.g. items.type="list") slipped past lint. - OrderedProps.MarshalJSON falls back to alphabetical key order when Map has entries but Order is empty, instead of silently emitting {}. Tests pass locally and with CI=true env (simulating GitHub Actions). * chore(schema): refresh golden envelopes after meta_data drift Re-generated with UPDATE_GOLDEN=1 against the current meta_data.json snapshot. The bulk of the diff is upstream noise (description wording, enum entries, field order) which the CI snapshot diff can no longer reasonably gate (see previous commit). Side-effects of the code fixes in the parent commit are also captured: - integer-typed defaults now emit numeric literals (e.g. page_size default 500, not "500") thanks to coerceEnumValue - mail.user_mailbox.templates.create _meta.risk corrects to "write" (assembler already emitted "write"; the old golden was stale) * fix(schema): address CodeRabbit round-3 review findings - TestMain: cleanup now runs reliably. os.Exit skips deferred functions, so the previous defer os.RemoveAll(dir) never executed. Replace defer with explicit cleanup, and fail fast if MkdirTemp errors instead of silently running against the host cache (which defeats isolation). - convertProperty default coercion: when the literal cannot be coerced to the declared type (e.g. default:"" on integer field, used by meta_data to mean "no default"), omit the field entirely rather than emit a type-mismatched default. Removes a contract violation flagged on im.reactions.list.json#page_size. * feat(schema): wire affordance overlay into envelope _meta Replace the loadAffordance stub (which always returned nil and read from an empty embedded annotations/ directory) with parseAffordance, which lifts the affordance block from method["affordance"]. The block is authored under larksuite-cli-registry's registry-config.yaml in the overrides: section and flows through gen-registry.py's deep_merge into the embedded meta_data.json. Simplify buildMeta signature: the service/resourcePath/method args existed only to feed the old dotted-path lookup. Refresh 9 golden envelopes for unrelated upstream meta_data.json drift. * refactor(schema): drop x-in extension from inputSchema x-in (path/query/body) was an HTTP-shape leak in a CLI-facing tool spec. AI consumers call the CLI by name with named args — they never construct HTTP requests directly, so the path-vs-body-vs-query distinction is the CLI's internal concern, not part of the contract. Execution path (cmd/service/service.go) already reads location from meta_data.json directly, so removing x-in does not affect routing. Drop: - Property.XIn field - validXIn map and the two lint rules that depend on x-in (L1 "top-level missing x-in" and L2 "path field must be in required") - contains() helper, no longer referenced after the path-required rule went away Refresh 20 goldens for the now-absent x-in lines. * refactor(schema): wrap inputSchema into params/data/flags sub-objects Replace the flat inputSchema with a 3-bucket nested structure that mirrors the CLI's actual flag layout, so AI consumers can directly map envelope fields to lark-cli invocation: inputSchema: properties: params: { ...path + query fields } → CLI --params JSON data: { ...body fields } → CLI --data JSON flags: { yes: ... } → CLI --yes (only for high-risk-write) Each sub-object only appears when the method has the corresponding source, so read-only GETs have a single `params` block, body-only POSTs have a single `data` block, etc. The `flags` wrapper carries an explicit description marking it as a CLI control bucket (not API fields), so AI does not confuse `yes` with a backend parameter. Lint: - L2 walkForL2 helper recurses into params/data sub-objects so leaf invariants (format:binary on non-string, min<max, required-in-properties) still apply. - L3 yes-presence check now navigates flags.properties.yes. Refresh all 20 goldens for the new shape. * refactor(schema): drop flags wrapper, put yes at top level alongside params/data The flags wrapper added one extra layer for a single field. Flatten so inputSchema.properties has three siblings: inputSchema: properties: params: { ...path + query } → CLI --params data: { ...body } → CLI --data yes: { boolean, default:false } → CLI --yes (only when risk == high-risk-write) `yes` description strengthened to mark it as a CLI confirmation gate (consumed by lark-cli, not sent to the backend), so AI can still distinguish it from API fields without needing a wrapper. Lint L3 yes-presence check goes back to top-level Properties.Map["yes"]. Refresh 20 goldens. * feat(schema): add `file` top-level sub-object for binary upload fields Splits file fields out of `data` into their own sibling, so the four top-level slots in inputSchema map 1:1 to CLI flag dispatch: inputSchema.properties: params { path + query fields } → --params JSON data { non-file body fields } → --data JSON file { type:file body fields, format:binary } → --file <key>=<path> yes boolean → --yes (only when risk == high-risk-write) Each slot is conditional: only registered when the method actually has fields for that source. This matches the CLI's own conditional flag registration (cmd/service/service.go:170-195), so what AI sees in the schema is exactly what flags exist for that method. The file sub-object carries a description explaining its semantics so AI knows to use --file for those fields rather than embedding the binary in --data JSON. Refresh im.images.create golden (the only file-upload method in the golden set). * test(schema): cover L2 lint recursion into params/data sub-objects Add two negative test cases that stuff bad values inside the wrapped inputSchema sub-objects (rather than at top-level), to lock in walkForL2's recursive coverage: - format:binary on a non-string field nested under params - sub-object Required referencing a key not in its Properties Regression guard so future walkForL2 refactors do not silently lose recursion and let leaf-field violations slip past lint. * fix(schema): coerce example, aggregate nested required, fix path hint - coerce `example` literal to the declared JSON Schema type (rename coerceEnumValue -> coerceLiteral, drop on coerce failure to match the `default` policy). Without this, integer/boolean/number fields emitted string examples and failed strict validators. - aggregate child field `required:true` into the enclosing nested object's `required[]` (both object and array-items shapes). Previously only the top-level params/data sub-objects scanned `required`, so envelopes silently under-reported the real call contract. - check method existence before reporting trailing-segment failure in both JSON and pretty `schema` paths. A typo like `schema im messages typo extra` now reports "Unknown method: im.messages.typo" instead of the misleading "Method 'typo' exists but trailing segments ..." hint. - extract risk level constants (RiskRead / RiskWrite / RiskHighRiskWrite) in internal/cmdutil/risk.go; replace literal usages in schema, lint, and confirm helpers so the typo radius is one file. - reconcile AssembleEnvelope docstring with implementation reality (the package-level currentMethodOrder + assembleMu serialize concurrent callers; output is deterministic per inputs). - drop testdata/golden/ and golden_test harness. End-to-end envelope shape regression now relies on real CLI invocations and the existing property-level unit + lint coverage. * fix(schema): emit items:{} for all typeless arrays, restore lint gate The list→array fallback only added items:{} when the source type was "list", leaving ~64 natively-typed array fields (e.g. approval.instances.cc.cc_user_ids) as {type:"array"} with no items. These violated the L1 lint rule, but TestAllEnvelopesPass skipped the "array missing items" error as a known data inconsistency, so the MCP tool contract was not actually lint-clean. Relax the fallback to cover every array lacking element shape regardless of source type, and drop the lint-test skip so the gate is hard again.	2026-05-27 12:04:01 +08:00
