test(markdown): make disappearing-upload-file cases deterministic

The three temporary_file_disappears_before_stat subtests raced a polling goroutine against a 16MB write, hoping the removal landed between write and stat. On fast CI runners the window is routinely missed, failing Coverage jobs on main and every open PR. Replace the race with an injectable markdownStatUpload seam that removes the file before delegating to os.Stat.

 # Repository Agent Guide

-This file applies to the entire repository. Keep it as a routing page: load
-the detailed guide for the surface you are changing instead of treating this
-file as a repository wiki.
+This file applies to the entire repository. Keep changes scoped, preserve
+unrelated work, and use `gofmt` for every modified Go file.

-## Always
+## Build and test

- Preserve unrelated and pre-existing work; inspect `git status` before edits.
- Make the smallest coherent change and update its tests and user-facing docs.
- Use `gofmt` for every modified Go file.
- Treat repository code, tests, scripts, and versioned docs as the source of
-  truth. Do not depend on generated Wiki or CodeWiki content.
- Do not hand-edit generated Schema Catalog or Agent metadata. Change their
-  reviewed inputs or generators, then regenerate.
+- Build: `go build ./cmd`
+- Full test suite: `DWS_PACKAGE_VERSION=0.0.0-test go test ./...`
+- Generate Schema assets: `go generate ./internal/cli`
+- Check generated drift: `./scripts/policy/check-generated-drift.sh`
+- Check the Schema contract: `./scripts/policy/check-schema-catalog.sh`

-## Read by task
+Generated Schema JSON is committed. Change its source inputs and generators,
+then regenerate; do not hand-edit generated Catalog or Agent metadata files.
+`internal/cli/schema_command_registry.json` is different: it is a reviewed
+`CommandRegistry` source, not a generated snapshot. It is the single reviewed
+source of stable canonical identity,
+primary paths, aliases, and navigation. Edit it only when reviewed exposure,
+identity, primary path, or aliases change; parameter, Skill, and metadata-only
+changes must not rewrite it mechanically.

+## Agent Schema contract

-Read the closest code and tests for the affected package as well. Nested
-`AGENTS.md` files take precedence for their subtrees.
+The Schema data flow is one way:

-## Common checks
+```text
+1. app.NewRootCommand()
+   └─ builds the real Cobra command tree and flags

-Choose checks from the matrix in `docs/coding-agent-guide.md`; do not claim a
-check that was not run.
+2. schema_command_registry.json
+   + schema_hints/metadata/<product>.json tool parameters (+ cli_path)
+   └─ forms EffectiveCommandRegistry
+      └─ binds exactly to real Cobra leaves and aliases

-```bash
-make coding-agent-harness
-make build
-make format-check
-make test
-make policy
-git diff --check
+3. Parameter resolution
+   Cobra flags
+   + schema_parameter_bindings.json
+   + metadata tool parameters
+   └─ produces ParameterSpec and constraints
+
+4. Agent and interface semantics
+   schema_hints/selection/<product>.json   (selection prose)
+   + schema_hints/metadata/<product>.json  (safety/interface/runtime_gate)
+   + pinned MCP metadata
+   └─ resolves Agent metadata by source precedence
+      Markdown is evidence only; it is not concatenated into final prose
+
+5. One typed hub
+   BoundCommandRegistry
+   + ParameterSpec
+   + Agent metadata
+   + Interface metadata
+   └─ resolves every command exactly once into ToolSpec
+      └─ aggregates SchemaRegistry + SchemaIndex
+
+6. One-way publication
+   SchemaRegistry
+   └─ internal/cli/schema_catalog.json
+      └─ dws schema list/product/group/leaf/--all
 ```

-For Schema work, the minimum generation entry point is `make generate-schema`.
-For CLI path or flag changes, also run
-`./scripts/policy/check-command-surface.sh --strict`. Report failures,
-environment limits, and unrun checks explicitly in the handoff.
+Parameter overlays from metadata are merged into `EffectiveCommandRegistry`
+*before* Cobra binding; after that point there is no second identity source and
+no identity precedence winner. The binder must reject a missing/non-runnable
+Cobra path, an alias collision, and any native identity annotation that
+disagrees with the effective registry. A missing native identity annotation is
+allowed because annotations are implementation-side assertions, not identity
+fallbacks.
+
+The assembler resolves every bound command exactly once into one `ToolSpec`.
+Build-time gates and the snapshot serializer consume that source-resolved typed
+registry/index. Runtime projections and delivery gates consume the typed
+registry/index returned by the production snapshot loader. Neither path may
+reopen annotations, merge source records, or use a previous Catalog or other
+generated JSON as a source. `schema_catalog.json` is output-only in the
+generation graph. The production loader decoding the embedded published
+snapshot is a delivery boundary, not source resolution; it must never create or
+repair a Cobra command, flag, registry entry, or later Catalog generation.
+
+This split is architecturally isomorphic to Lark's typed metadata registry,
+navigation catalog, and schema renderer. DWS intentionally preserves its
+existing flat JSON wire contract for compatibility; do not treat architectural
+alignment as permission to make an unversioned wire-format change.
+
+The reviewed `CommandRegistry` is the sole source of stable command identity
+and navigation. The executable Cobra tree remains the source of truth for
+whether a CLI path exists, is runnable, and which flags it accepts. Schema
+coverage is bidirectional:
+
+1. Every final `SchemaRegistry` tool, including its serialized Catalog
+   projection, must resolve to an executable Cobra command.
+2. Every public runnable Cobra leaf must either resolve to Schema or appear as
+   an exact, reviewed exclusion with a non-empty reason in
+   `internal/cli/schema_command_exclusions.json`.
+
+Do not use prefix or wildcard exclusions: they can silently hide future
+commands. Remove an exclusion when its command enters Schema; stale, invalid,
+or duplicate exclusions must fail generation and CI.
+
+When adding or changing an Agent-visible command, review all relevant inputs:
+
+- `internal/cli/schema_command_registry.json` for the reviewed
+  `CommandRegistry`: canonical identity, primary CLI path, aliases, and stable
+  navigation. It is the identity source and is not a generated artifact.
+- `internal/cli/schema_command_registry.schema.json` is its closed,
+  machine-readable editing contract. Preserve the local `$schema` reference;
+  unknown fields, invalid visibility values, stale paths, and collisions fail
+  Go validation and policy.
+- `internal/cli/schema_hints/metadata/<product>.json` for safety, interface,
+  `runtime_gate`, and optional parameter overlays (`parameters` / `cli_path`).
+- `internal/cli/schema_hints/selection/<product>.json` for reviewed Agent
+  selection prose (`agent_summary`, `use_when`, `avoid_when`, `examples`).
+- `internal/cli/schema_hints/index.json` only maps product IDs to those files.
+- Native Runtime Schema identity annotations, when present, as consistency
+  assertions against `EffectiveCommandRegistry`. They must agree exactly and
+  must never materialize, infer, or override registry identity.
+- Flag-to-interface property mappings and required/default semantics.
+- Generated files under `internal/cli/schema_agent_metadata/` and
+  `internal/cli/schema_catalog.json` after running generation.
+
+Run the reverse-completeness tests whenever the Cobra tree changes. A command
+that works through `dws <path>` but cannot be found through the matching
+`dws schema` lookup is a contract failure unless it has a reviewed exact
+exclusion.
+
+Metadata parameter overlays must reference an exact public runnable Cobra leaf
+and real flags. They may override Schema description, interface-property/type
+mapping, `required`, and `required_when`; they must not create commands or
+flags, define an interface, or advertise an unknown RPC. Every authored entry
+requires `reviewed: true` and a non-empty review reason.
+
+For Agent-authored metadata or selection edits:
+
+1. Confirm the exact command and flag names in the current Cobra tree.
+2. Edit only the owning block (`metadata/` or `selection/`); do not mix fields.
+3. Add the smallest possible entry; do not copy generated Catalog fields into
+   the input.
+4. Describe user-visible semantics in `review_reason` and parameter
+   descriptions.
+5. Run generation, drift, Schema policy, and the focused CLI tests before
+   proposing the change.
+
+## Agent curation workflow (Schema hints)
+
+Use this workflow when refreshing Agent selection prose and confirmation
+alignment. Prefer **agent-authored review** over bulk merge scripts that dump
+`selection-review.json` or Skill Markdown into Catalog fields.
+
+Human-authored inputs are split into two blocks:
+
+| Block | Path | Owns |
+|---|---|---|
+| **metadata** | `internal/cli/schema_hints/metadata/<product>.json` | `effect` / `risk` / `confirmation` / `idempotency` / `interface_*` / `runtime_gate` / optional `parameters` |
+| **selection** | `internal/cli/schema_hints/selection/<product>.json` | `agent_summary` / `use_when` / `avoid_when` / `examples` (+ product routing) |
+
+`index.json` only maps product IDs to those files. Do not mix selection fields
+into metadata files or metadata fields into selection files.
+
+### Goals
+
+1. **Selection prose** is decision-oriented (Feishu/Lark style): trigger intent,
+   sibling-command routing, and outcome shape — not a restatement of the
+   summary. Delivered Catalog provenance is `reviewed_explicit` from
+   `selection/`.
+2. **Safety** follows Runtime: `confirmation=user_required` iff the tool's
+   metadata `runtime_gate != none` (for example `confirm_delete`, `typed_yes`,
+   `confirm_dangerous`).
+3. **Parameter overrides** (former Manual `commands`) live on metadata tools as
+   `parameters` (+ `cli_path`) and are applied into EffectiveCommandRegistry.
+
+### Authoring
+
+For every curated tool:
+
+1. Edit `metadata/<product>.json` for safety/interface/gates/parameters.
+2. Edit `selection/<product>.json` for selection prose (`reviewed: true`,
+   `review_reason`, `source_refs`).
+3. Run `make generate-schema`. Do not hand-edit generated
+   `schema_agent_metadata/` or `schema_catalog.json`.
+
+### Pull live MCP descriptions (personal token)
+
+Pinned `internal/cli/schema_mcp_metadata.json` is a sanitized baseline. Prefer
+live Schema from a logged-in personal session:
+

+Resolve MCP identity via `interface_ref` when CLI canonical ≠ MCP path

+
+Precedence when sources disagree: **Runtime/Cobra > live MCP > pinned MCP >
+Skill (evidence only)**.
+
+### Parallel product agents
+
+Split work by product groups. Each agent must:
+
+- Read Skill, Cobra/`--help`, Runtime confirmation sites, and live `dws schema`
+  for its tools.
+- Hand-write selection + metadata; forbid wholesale JSON merges from review
+  dumps.
+- Edit only its `metadata/<product>.json` and `selection/<product>.json`.
+- **Never** `git checkout` unrelated product files to “clean scope”.
+
+### Regenerate and gates
+
+```bash
+make generate-schema
+./scripts/policy/check-runtime-confirmation-truth.sh
+go test ./internal/app -run '^TestSheetFinalSchemaConfirmationMatchesRuntimeGuards$' -count=1
+```
+
+Example rules (fail generation otherwise):
+
+- At most two examples per tool; no `--yes` in stored examples.
+- Examples must match live Cobra argv (path, flags, required groups).
+- No shell comments in examples.
+
+After generation, spot-check Catalog: selection provenance is
+`reviewed_explicit` from `selection/`, and `user_required` count equals
+metadata `runtime_gate != none`.
+
+`make generate-schema` is a full deterministic snapshot rebuild, not an
+incremental patch over the previous Catalog. It rereads every reviewed input,
+removes stale generated product metadata, and rewrites the exact metadata and
+Catalog projections. Incremental work happens only when an Agent or human
+edits selected `metadata/` or `selection/` entries; the next publication still
+recomputes all outputs. Generated files must never be read back as merge input,
+and byte guards fail generation if it changes the hint inputs or CommandRegistry.
+
+Selection prose may choose a more or less restrictive recommendation. It cannot
+create a Cobra command or flag, change parameter facts, invent an
+RPC/interface, alter safety metadata, or bypass command completeness. Examples
+must use an executable primary/alias path and flags accepted by the live Cobra
+command; never add `--yes` to stored examples.
+
+Every example is always checked against its real `BoundCommand`: exact path,
+accepted flags, Cobra required flags/positionals, and the effective
+`require_one_of`, `require_together`, and `mutually_exclusive` constraints must
+all pass before execution eligibility is considered. A missing required value,
+constraint failure, runtime error, or MCP resolution error is a contract bug;
+none is a valid reason to skip an example.
+
+Example execution defaults to contract validation only. Runtime execution is
+opt-in: an example enters `dry_run` only when its final `ToolSpec` publishes an
+explicit reviewed dry-run capability. The test never injects `--yes`, and
+`risk`/`confirmation` values do not manufacture preview support. A narrow
+runtime precondition that cannot be derived from the typed contract may use an
+exact zero-based `example_dispositions` entry with `mode=contract_only`,
+`reviewed=true`, one of the schema-enumerated reason codes, and a concrete
+non-empty reason. Such a disposition may only narrow an explicit dry-run
+capability; it cannot turn an ordinary contract-only example into a skip.
+Duplicate, missing, and out-of-range indexes fail validation. Never catch a
+dry-run failure and dynamically downgrade it to `contract_only`.
+
+Normal Go tests run the exhaustive contract gate. Run
+`make test-schema-agent-examples` to additionally execute the eligible subset
+through the real Cobra `--dry-run` path with isolated HOME and blocked proxies.
+The test reports stable `total`, `contract`, `dry_run`, `contract_only`,
+`reviewed_manual`, and per-reason counts; changing those counts requires a
+review of the corresponding typed dry-run capability or manual disposition.
+This target is also part of `make policy`.
+
+Treat every tool `use_when` entry as a reviewed positive selection scenario
+whose expected result is that tool's canonical path, and every `avoid_when`
+entry as a reviewed negative scenario that must not choose that tool. The
+deterministic gate derives a typed evaluation fixture from these same fields;
+it requires exact tool coverage, a real runnable `BoundCommandRegistry`
+primary command, at least one positive and negative assertion per tool, and no
+literal contradictory expectations. It does not claim that string matching
+proves natural-language understanding.
+
+Semantic selection is an explicit opt-in live-model check. Run the smoke set
+(one positive and one negative scenario per product) with
+`DWS_AGENT_SELECTION_LIVE=1 ARK_API_KEY=... ARK_BASE_URL=... ARK_MODEL=... go test ./internal/app -run TestManualAgentSelectionArkLive -count=1`.
+Add `DWS_AGENT_SELECTION_FULL=1` to evaluate every committed tool scenario, or
+set `DWS_AGENT_SELECTION_CASES` to comma-separated fixture case IDs. Normal CI
+never calls a model; its blockers remain the reproducible fixture, binding,
+example, provenance, and final-delivery facts.
+
+The live evaluator sends only case IDs/scenarios plus one same-product
+candidate table; expected/forbidden assertions stay local and must never be
+included in the model prompt. Built-in Ark HTTPS bases are allowlisted. A
+different HTTPS provider requires its exact base in
+`DWS_AGENT_SELECTION_ALLOWED_BASE_URLS`; plaintext HTTP is accepted only for a
+loopback test server so API credentials are never sent to an arbitrary clear
+text endpoint.
+
+## Safety metadata
+
+Parameter and safety resolution is mostly source-precedence based and
+value-neutral: do not choose a winner because one value looks stricter. A
+higher-priority reviewed metadata/explicit source may intentionally raise or
+lower description, mapping, `effect`, `risk`, `confirmation`, or `idempotency`.
+Preserve all candidates and the selected source in provenance, and fail
+same-precedence conflicts rather than silently merging them.
+
+`required` is the exception. Cobra `MarkFlagRequired` is a hard floor: the
+final Agent projection must keep `required=true` and cannot be lowered by
+manual/hint overlays. Overlays may still raise an optional flag to required.
+`cli_required` continues to mirror the executable Cobra marker.
+
+For command text, reviewed `ToolSchemaHint` wins first, then command-specific
+Cobra Help, then MCP metadata. Generic RPC prose may remain an unselected
+provenance candidate (and parameter-level `interface_description`); it must not
+overwrite a specialized leaf's title or description.
+
+For every delivered `ToolSpec` and `ParameterSpec` field, the provenance
+winner value must exactly equal the delivered value. Checking only source,
+count, presence, or hash is not a sufficient final-delivery invariant.
+
+The same resolved `ToolSpec` must drive every projection. The full leaf payload
+must equal the corresponding tool in `schema --all` and the full Catalog tool.
+Overview/product/group summaries and Catalog summaries must equal
+`ToolSpec.ToSummaryPayload()`. An alias lookup may change only the view fields
+`cli_path` and `is_alias`; it must not re-resolve or mutate the command
+contract.
+
+This build-time rule is distinct from runtime drift handling. If shipped Help
+and leaf Schema disagree, pass only flags accepted by Cobra. For conflicting
+safety information, do not silently take the less restrictive behavior: use
+the safer interpretation or stop and report the contract drift.
+
+Do not infer one safety field from another. In particular, `effect=destructive`
+or `risk=high` does not mechanically rewrite `confirmation`; the final
+precedence winner for each field is authoritative. When
+`confirmation=user_required`, obtain confirmation before adding `--yes`.
+Keep CLI confirmation behavior and Schema metadata consistent, and add a
+semantic regression test through the final embedded loader/query delivery
+path; a generator unit test or JSON count alone is insufficient.
+
+## Current Schema boundaries
+
+- `schema list` remains a progressive overview. `schema --all` is the stable
+  full-export contract: every final `SchemaIndex` tool must contain its
+  complete leaf parameters, constraints, and safety semantics, including an empty
+  `parameters` object for commands without flags. Keep it suitable for the #602
+  compatibility baseline and fail rather than silently emitting a partial
+  export.
+- `schema --all` is not normal command discovery. Use overview -> product/group
+  -> leaf for routine Agent work. `--compact` is supported for context-saving
+  projections, but a compact full export is not a complete compatibility
+  baseline.
+- `dws <path> --help` defines whether Cobra exposes a path and which flags the
+  executable accepts. A leaf Schema defines Agent selection, parameter mapping
+  and constraints, and safety/confirmation semantics. A conflict is contract
+  drift, not permission to guess.
+- Schema and Help describe commands; neither returns DingTalk business data.
+  After discovery, execute the real read/search/list command to obtain data.

+## [1.0.55-beta.2] - 2026-07-23
+
+This beta validates Wukong capability parity across Chat, Contacts, documents,
+Drive, Markdown, and Todos, together with faster guarded releases and legacy
+authentication migration.
+
+### Added
+
+- **Chat editing and group management** — adds `chat message edit`, conversation-category lookups through `chat category list-by-conv` and `chat category batch-info`, and the confirmed, irreversible `chat group upgrade-to-external` flow.
+- **Contact maintenance commands** — adds `contact user update`, `contact user update-self`, `contact dept create`, `contact dept update`, and `contact account update`, all with guarded write behavior.
+- **Markdown file workflows** — adds the `markdown` product with `fetch`, `create`, `overwrite`, and `patch` commands for Drive-native `.md` files, including explicit routing, dry-run previews, and confirmation for destructive writes.
+- **Todo labels** — adds `todo tag add`, `delete`, `update`, `list`, and `create`.
+
+### Changed
+
+- **Faster guarded releases** — trusts an independently revalidated, exact `CHANGELOG.md`-only successor of an already admitted `main` commit, runs cloud planning alongside governance, and executes sealed-release automation, compatibility, and multi-profile validation in parallel with artifact compilation. Normal cloud publication no longer requires an unshareable local packaging preflight.
+- **Scoped document reads and group mentions** — `doc read --content-format jsonml` can return `outline`, `range`, `section`, or custom-tag fragments with depth and block-boundary controls; document comment create, reply, and update can mention groups through `--mentioned-open-conversation-id`.
+- **Drive overwrite uploads** — `drive upload --node <fileId>` can replace an existing Drive or document-space file, is mutually exclusive with `--folder`, supports dry-run, and requires confirmation before writing.
+- **Chat nickname clearing and cross-organization todos** — omitting `--nick` from `chat group update-nick` now clears the current user's group nickname, while `todo task list --query-all` queries todos across organizations.
+
+### Fixed
+
+- **Legacy authentication compatibility** (#756) — migrates pre-v1.0.53 global and organization-scoped login state into the identity-aware token store, including all legacy organizations, while keeping unresolved accounts isolated from exact `corpId:userId` credentials so external or no-directory identities can complete login without borrowing another user's token.
+
+## [1.0.55-beta.1] - 2026-07-23
+
+This beta validates MCP Market URL resolution, the supported Wukong local-file
+send path after retiring the legacy credential-based media upload command from
+discovery, and reliable message-read rendering for rich content, forwarded
+records, encrypted messages, and media-download ID aliases.
+
+### Added
+
+- **MCP URL resolution** — adds `dws mcp url get <mcpId>` for resolving a DingTalk MCP Market ID to the current user and organization scoped Streamable HTTP URL, while keeping the helper-only `mcp-meta` endpoint out of the public product command surface.
+
+### Changed
+
+- **Chat local-file sending** — hides the open-source-only `chat media upload` compatibility command from Help, Schema, and bundled Skills, and removes its legacy AppKey/AppSecret OAPI path. Historical argv still receives an actionable migration error. Send local images and files through `chat message send --msg-type file --file-path`; callers that already hold a mediaId may continue to use `--msg-type image --media-id`.
+
+### Fixed
+
+- **Message-read shortcut projection** (#706) — the message-list shortcuts (`chat +chat-messages` / `+messages-list` / `+messages-list-direct` / `+at-me` / `+search-msg` / `+thread-replies`) now render card and out-of-office rich-content JSON as readable text (without ever rewriting ordinary text that merely embeds a JSON fragment), expand a forwarded chat record's nested `forwardMessages` instead of collapsing to a "[卡片]" summary, and mark undecryptable encrypted card messages as `[加密消息]`; the speaker is read from the bare `sender` key, nested `{name:…}` sender objects yield their display name, and the literal string `"null"` is treated as absent. Shared projection helpers now live in `internal/shortcut/chatmsg`. `chat message download-media` also gains `--msg-id` / `--open-message-id` aliases for its `--message-id` flag so agents copying the `openMessageId`/`msgId` output field no longer hit "unknown flag".
+
 ## [1.0.54] - 2026-07-21

 This release promotes the validated `v1.0.54-beta.2` baseline to stable. It restores the default transport envelope for personal event output with opt-in flattening, plus Schema CLI path and plugin overlay compatibility fixes.

-3. New shared behavior joins the existing shared package that owns the
-   contract; do not create a new shared package for a single caller.
-4. Schema/Agent metadata changes start from reviewed inputs in `internal/cli`
-   per [`schema-contributor-guide.md`](schema-contributor-guide.md); never
-   hand-edit generated Catalog output.
-5. Bundled skill content under `skills/` follows
-   [`skill-authoring-guide.md`](skill-authoring-guide.md); skills are embedded
-   via `skills/embed.go` and ship with the binary.
-6. A new top-level package (under `internal/` or `pkg/`) requires a stated
-   boundary reason in its PR and an update to the Repository Structure list

-# Coding Agent Workflow
-
-This is the task intake and self-check contract for coding agents working in
-this repository. It is intentionally independent of external Wiki systems:
-the checked-out repository is the execution context and evidence source.
-
-## 1. Normalize the task input
-
-Start from the copyable
-[`coding-agent-task-template.md`](coding-agent-task-template.md). Keep one
-primary outcome per task. Fill unknown fields from the issue, nearby code,
-tests, and versioned docs; state any assumption that can affect behavior.
-
-For a saved, filled template, run `make coding-agent-task TASK=path/to/task.md`.
-The local checker rejects missing required fields, unsupported task kinds, and
-unresolved placeholders before implementation begins.
-
-Do not invent acceptance criteria that expand the requested behavior. Stop for
-user input only when the unresolved choice would change externally visible
-behavior, compatibility, destructive scope, credentials, or external state.
-
-## 2. Establish the baseline
-
-1. Run `git status --short` and identify pre-existing changes.
-2. Read the applicable guides linked from the root `AGENTS.md`.
-3. Locate the implementation and its closest tests with `rg`/`rg --files`.
-4. Reproduce the bug or capture the current contract before changing it.
-5. Pick the smallest owning layer; avoid duplicating policy in a caller when a
-   shared typed layer already owns it.
-
-Never clean, overwrite, stage, or reformat unrelated user changes. If a
-required file is already modified, inspect the overlap and preserve both
-intents or stop with the exact conflict.
-
-## 3. Implement from authoritative inputs
-
- Go behavior belongs in the package that owns the contract, with focused
-  tests beside it.
- Product handlers under `internal/helpers` follow
-  [`helpers-structure-guide.md`](helpers-structure-guide.md): thin
-  `{product}.go` wiring plus `{product}_{resource}.go` files; do not enlarge
-  megafiles such as `chat.go`.
- Public CLI paths and flags must match the live Cobra tree and compatibility
-  policies.
- Schema and Agent-facing changes start from reviewed source inputs; generated
-  outputs are publication artifacts.
- Documentation describes behavior that exists in the same change.
- Secrets, tokens, local identities, and private endpoints must not enter code,
-  fixtures, logs, or handoff output.
-
-For generated files, run the repository generator and inspect the resulting
-diff. A large or unrelated generated diff is a signal to stop and find the
-wrong input or nondeterminism, not something to accept automatically.
-
-## 4. Select validation by change surface
-
-Run the narrow check while iterating, then the applicable admission checks
-before handoff. `make help` is the authoritative target list.
-
-| Changed surface | Focused check | Admission checks |
-|---|---|---|
-| Documentation only | inspect links/examples | `git diff --check` |
-| Go implementation | `go test ./path/to/package` | `make format-check`, `make test` |
-| CLI paths or flags | focused command/help tests | `make build`, `./scripts/policy/check-command-surface.sh --strict`, `make interface-integrity` |
-| Schema registry, hints, or generators | focused generator/app tests | `make generate-schema`, `./scripts/policy/check-generated-drift.sh`, `./scripts/policy/check-schema-catalog.sh`, `make test-schema-agent-examples` |
-| Skill command examples | inspect referenced `dws` help | `make skill-command-integrity` |
-| CI or test sharding | run the affected script/test | `make test-plan`, `make lint`, and the CI workflow's pinned actionlint command when workflows change |
-| Packaging or installers | focused release-script tests | `make package`, `./scripts/release/verify-package-managers.sh` |
-| Authentication, transport, or OS-specific code | focused tests, including failure paths | `make test`; run relevant platform checks or disclose the unavailable platform |
-
-`make policy` is the combined policy gate and is appropriate for command,
-Schema, generated-asset, or broad cross-cutting changes. Platform credentials
-and live services are not prerequisites for ordinary unit tests; never turn a
-missing credential into permission to skip deterministic checks.
-
-The guide contract itself is executable. Run `make coding-agent-harness` after
-changing `AGENTS.md`, this guide, the Schema contributor guide, helpers
-structure guide, or their routed commands and paths. This remains a local,
-opt-in agent aid and is not wired into CI.
-
-## Design references
-
-This repository adapts two patterns without copying their product-specific
-rules:

- [Lark CLI's contributor guide](https://github.com/larksuite/cli/blob/5efaf65aec59c33899475bb90e6bff1bc3b5b65c/AGENTS.md): one primary goal, machine-consumable errors/output, and validation selected by behavior surface.
- [WeCom CLI's root routing guide](https://github.com/WecomTeam/wecom-cli/blob/9eb7898b959861af879495e211e37431fa908f19/AGENTS.md) and [human helper template](https://github.com/WecomTeam/wecom-cli/blob/9eb7898b959861af879495e211e37431fa908f19/src/helpers/HUMANS.md): a thin root guide, scoped implementation guidance, and a copyable request format.
-
-## 5. Pre-handoff self-check
-
-Confirm every applicable item:
-
- The diff implements the stated goal and no unrelated cleanup.
- Pre-existing changes are still present and were not attributed to this task.
- New behavior has a regression test; removed behavior has an explicit reason.
- Public command paths, flags, output, exit behavior, and compatibility remain
-  intentional.
- Destructive or mutating operations retain the required confirmation path.
- Generated files came from their reviewed inputs and generation is clean.
- Docs and examples use commands accepted by current help/Schema.
- Errors preserve actionable context without leaking secrets.
- `git diff --check` passes and the final diff has been read.
- Every reported check is labeled passed, failed, or not run with a reason.
-
-Use this compact handoff shape:
-
-```text
-Outcome: what is now true
-Files: intentional files changed
-Validation: exact commands and results
-Limits: unrun checks, environment constraints, follow-ups

-# Helpers Package Structure Guide
-
-This is the coding-structure contract for product commands under
-`internal/helpers/`. Business teams and coding agents must follow it when
-adding or moving CLI leaves. Behavioral contracts (stdout, errors, confirmation,
-Schema) stay in [`internal/helpers/AGENTS.md`](../internal/helpers/AGENTS.md);
-this document only owns file layout and split rules.
-
-Reference implementations already in-tree:
-
-| Pattern | Use as |
-|---|---|
-| [`sheet.go`](../internal/helpers/sheet.go) + `sheet_*.go` | Preferred product layout: thin root wiring, resource files |
-| [`chat_media_upload.go`](../internal/helpers/chat_media_upload.go) | Incremental extract from a megafile without behavior change |
-| `connect_*.go` | Concern-based split inside the same `helpers` package |
-
-Anti-pattern to stop growing: single megafiles such as `chat.go` / `aitable.go`
-(thousands of lines). New work must not enlarge them.
-
-## 1. Package boundary
-
-Keep product handlers in the flat package `helpers`:
-
-```text
-internal/helpers/                 # package helpers (default)
-  register_products.go            # public product registration table
-  {product}.go                    # product root: new{Product}Command()
-  {product}_{resource}.go         # one resource / cohesive concern
-  {product}_{resource}_test.go    # focused tests beside the file
-  helpers.go / interfaces.go …    # cross-product shared machinery
-```
-
-Do **not** create `internal/helpers/{product}/` subpackages by default. The flat
-package exists so leaves can share unexported helpers (`callMCPToolOnServer`,
-flag validators, confirmation wrappers, transport adapters) without exporting a
-public API surface. Split into a subpackage only when the concern is a real
-library boundary with its own tests and almost no need for helpers-private
-symbols—and get an explicit review for that exception.
-
-Repository layers outside helpers stay unchanged:
-
-| Layer | Owns |
-|---|---|
-| `internal/app` | Root/static wiring, plugin load |
-| `internal/helpers` | Product Cobra trees and handler behavior |
-| `internal/cobracmd` | Shared Cobra construction primitives |
-| `internal/executor`, `internal/transport` | Invocation and transport |
-| `internal/output`, `internal/errors`, `internal/safety` | Projection, failures, confirmation |
-| `internal/cli` | Schema identity / Agent metadata |
-
-Ordinary product leaves belong in helpers. Do not push product business mapping
-into app, transport, or Schema generators.
-
-## 2. File roles inside a product
-
-### 2.1 Product root — `{product}.go`
-
-Owns exactly one entry constructor, registered from `register_products.go`:
-
-```go
-func newChatCommand() *cobra.Command { /* wire subgroups only */ }
-```
-
-The root file should:
-
-1. Define the product `cobra.Command` (`Use` / `Short` / `Long` / aliases).
-2. Call resource factories and `AddCommand` them.
-3. Register product-level aliases or hint stubs when needed.
-4. Avoid large inline `RunE` bodies for leaves.
-
-Target size: wiring-only, roughly under **400 lines** (see `sheet.go` ≈ 270).
-If the root grows past that because leaves are inlined, extract a resource file.
-
-### 2.2 Resource / concern file — `{product}_{resource}.go`
-
-Split on the **CLI path segment or cohesive concern**, not on “one function per
-file”:
-
-| CLI path | File |
-|---|---|
-| `dws chat group …` | `chat_group.go` |
-| `dws chat message …` | `chat_message.go` |
-| `dws chat media …` | `chat_media_upload.go` (or `chat_media.go`) |
-| `dws sheet filter-view …` | `sheet_filter_view.go` |
-| `dws sheet dimension …` | `sheet_dimension.go` |
-
-Each file exposes one or more unexported factories, for example:
-
-```go
-func newChatGroupCmd() *cobra.Command { … }
-func newChatMessageCmd() *cobra.Command { … }
-func newWorkbookCmds() []*cobra.Command { … }
-```
-
-The product root only wires those factories. Prefer keeping a leaf’s flags,
-`RunE`, and nearby request-mapping helpers in the same resource file until a
-helper is reused by multiple resources.
-
-Soft size guide per resource file:
-
-| Lines | Action |
-|---|---|
-| &lt; 600 | Normal |
-| 600–1000 | Prefer splitting the next cohesive subgroup before adding more |
-| &gt; 1000 | Required split before landing substantial new leaves |
-
-“One command per file” is **not** required. Tiny sibling leaves that share
-flags and mapping belong together. Split when the file holds multiple unrelated
-resources or becomes hard to review.
-
-### 2.3 Shared product helpers — `{product}_{concern}.go`
-
-Use a concern suffix when code is shared across resources and is not itself a
-command tree:
-
- `sheet_validate.go` — shared validation
- `chat_args.go` / similar — grant/arg builders used by several leaves
- `connect_command.go` — slash-command parsing used by the daemon
-
-Do not park unrelated products’ utilities in these files. Cross-product
-machinery belongs in non-prefixed shared files (`helpers.go`, `interfaces.go`,
-output/error helpers), never copied per product.
-
-### 2.4 Tests
-
- Name tests after the file or scenario: `chat_message_search_test.go`,
-  `sheet_filter_view_test.go`.
- Prefer exercising public product construction (`newChatCommand().Find(…)`)
-  for command-surface regressions.
- Pure helpers may be unit-tested directly in the same package.
- A mechanical file split without behavior change should keep existing tests
-  green with no assertion edits; if tests must change, the split leaked a
-  behavior or visibility change and needs review.
-
-## 3. Registration and naming
-
-1. Public products enter the CLI only through the table in
-   `register_products.go` (`new{Product}Command` factories). Do not invent a
-   second registration path for ordinary product leaves.
-2. Constructor names stay unexported (`new…`) unless a deliberate test helper
-   requires otherwise.
-3. File names are lowercase snake_case. Match the CLI resource token when
-   practical (`filter-view` → `filter_view`).
-4. Do not hand-edit generated sync markers in `register_products.go` outside
-   the product-registration workflow that owns that file.
-
-## 4. How to add a new command (business-team checklist)
-
-1. Confirm the owning product and CLI path with `dws <product> --help`.
-2. Open `{product}.go` only to wire `AddCommand`; put the leaf in
-   `{product}_{resource}.go`.
-3. If the product is still a megafile (`chat.go`, `aitable.go`, …) and your
-   resource file does not exist yet, **create the resource file and move only
-   the subgroup you need** (or add the new leaf there and wire it from the
-   root). Do not append another large leaf into the megafile.
-4. Keep stdout / stderr / error / confirmation contracts from
-   `internal/helpers/AGENTS.md`.
-5. If path, flags, safety, or Agent selection change, follow
-   [`schema-contributor-guide.md`](schema-contributor-guide.md).
-6. Add or extend the closest test; run
-   `go test ./internal/helpers -count=1` (or a tighter `-run`) plus the checks
-   selected by [`coding-agent-guide.md`](coding-agent-guide.md).
-
-## 5. Migrating an existing megafile
-
-Mechanical splits are welcome and preferred over “big-bang” rewrites.
-
-Rules for a split PR:
-
-1. **Behavior-neutral**: same command paths, flags, help text, request mapping,
-   confirmation, and output.
-2. **Stable entrypoint**: keep `new{Product}Command()` as the registration
-   symbol; only its body becomes wiring.
-3. **Move by resource**: extract one CLI subgroup per commit/PR when possible
-   (`group`, `message`, `category`, …).
-4. **No drive-by cleanups** in the same PR (renames, flag redesign, Schema
-   edits) unless the task explicitly includes them.
-5. **Stop growing the megafile**: after the first extract, new leaves for that
-   resource go to the new file only.
-
-Suggested first-wave split for `chat` (illustrative, not mandatory order):
-
-| Extract to | Contents |
-|---|---|
-| `chat.go` | `newChatCommand()` wiring only |
-| `chat_permission.go` | `chmod`, `data-auth` |
-| `chat_group.go` | `group` tree |
-| `chat_message.go` | `message` tree |
-| `chat_category.go` | `category` tree |
-| `chat_bot.go` | `bot` tree |
-| `chat_conversation.go` | top-level conversation ops (`set-top`, mute, red-point, …) |
-| existing `chat_media_upload.go` | keep; optionally rename to `chat_media.go` only in a dedicated rename PR |
-
-Apply the same pattern to `aitable`, `attendance`, `mail`, and `doc` when those
-products take new work.
-
-## 6. What this guide does not change
-
- Wire format, MCP method names, or Schema identity rules.
- The choice to keep `package helpers` flat.
- Runtime confirmation / dry-run policy (still owned by safety + Schema metadata).
- Permission to skip tests because a change was “only a move”—moves still need
-  the product’s focused tests green.
-
-## 7. Harness check
-
-After editing this guide or its links from `AGENTS.md` /
-`internal/helpers/AGENTS.md`, run:
-
-```bash
-make coding-agent-harness
-```
-
-This check is a local, opt-in agent aid; it is not part of `make policy` or CI.

-# Schema and Agent Contract Contributor Guide
-
-Read this guide when changing public CLI commands, Schema identity or
-parameters, Agent selection/safety metadata, or generated Schema assets.
-
-## Ownership and data flow
-
-The publication graph is one way:
-
-```text
-Cobra command tree
-  + reviewed CommandRegistry identity/navigation
-  + reviewed metadata parameter overlays
-  -> EffectiveCommandRegistry and executable binding
-  + parameter bindings
-  + reviewed selection and safety/interface metadata
-  + pinned MCP metadata
-  -> one resolved ToolSpec registry/index
-  -> generated Agent metadata and embedded Schema Catalog
-  -> dws schema projections and runtime metadata lookup
-```
-
-The owning sources are:
-
-| Concern | Authoritative input |
-|---|---|
-| Executable paths and accepted flags | Cobra tree built by `app.NewRootCommand()` |
-| Stable canonical identity, primary path, aliases, navigation | `internal/cli/schema_command_registry.json` |
-| Registry editing contract | `internal/cli/schema_command_registry.schema.json` |
-| Safety, interface, runtime gates, parameter overlays | `internal/cli/schema_hints/metadata/<product>.json` |
-| Agent selection prose and examples | `internal/cli/schema_hints/selection/<product>.json` |
-| Product-to-hint-file routing | `internal/cli/schema_hints/index.json` |
-| Flag/property bindings | `internal/cli/schema_parameter_bindings.json` |
-| Sanitized interface fallback | `internal/cli/schema_mcp_metadata.json` |
-| Exact reviewed omissions from Schema | `internal/cli/schema_command_exclusions.json` |
-
-Generated files under `internal/cli/schema_agent_metadata/` and
-`internal/cli/schema_catalog.json` are output only. Runtime loading is a delivery
-boundary: it must not create or repair commands, flags, registry entries, or
-generation inputs.
-
-## Invariants
-
-1. Every delivered tool resolves to a public runnable Cobra leaf.
-2. Every public runnable Cobra leaf resolves to Schema or has one exact,
-   reviewed exclusion with a non-empty reason. Wildcard/prefix exclusions are
-   forbidden.
-3. The reviewed CommandRegistry is the only stable identity/navigation source.
-   Native annotations, when present, are consistency assertions and must agree.
-4. Metadata overlays may describe or constrain real flags; they cannot create
-   commands, flags, interfaces, or unknown RPCs.
-5. Cobra-required flags are a hard floor. An overlay may make an optional flag
-   required but cannot make a Cobra-required flag optional.
-6. Each tool is resolved once into one typed `ToolSpec`; all Catalog, `schema
-   --all`, leaf, summary, safety, and runtime projections derive from it.
-7. Provenance winner values must equal delivered values. Same-precedence
-   conflicts fail instead of being merged silently.
-8. `confirmation=user_required` requires user confirmation before `--yes`.
-   Do not infer confirmation mechanically from risk/effect; keep runtime gates
-   and published metadata consistent.
-9. Stored examples use real primary/alias paths and accepted flags, satisfy all
-   required/constraint rules, contain no shell comments, and never add `--yes`.
-10. `schema --all` remains the complete compatibility export. Routine discovery
-    should use overview, product/group, then leaf queries.
-
-When Help and shipped Schema disagree, treat it as contract drift. Cobra still
-defines executable flags; use the safer interpretation for confirmation or
-stop rather than guessing.
-
-Parameter and safety resolution is source-precedence based and otherwise
-value-neutral: a value must not win merely because it looks stricter. Preserve
-all candidates and the selected source, and fail same-precedence conflicts.
-Command text resolves from reviewed tool hints, then command-specific Cobra
-help, then MCP metadata; generic RPC prose must not replace a specialized
-leaf's description. An alias lookup may change only view fields such as
-`cli_path` and `is_alias`, never the resolved command contract.
-
-## Editing workflow
-
-1. Confirm the live path and flags in the Cobra tree and current `--help`.
-2. Change only the owning reviewed block. Do not copy generated Catalog fields
-   into inputs or mix selection fields into metadata files.
-3. Keep registry edits limited to intentional identity/navigation changes.
-4. For selection prose, write decision-oriented routing: when to choose the
-   command, when a sibling is better, and the result shape. Do not restate help.
-5. For parameter overlays, use an exact runnable leaf and real flags; set
-   `reviewed: true` with a concrete review reason.
-6. Regenerate the complete snapshot; publication is deterministic even when
-   only one product input changed.
-7. Inspect authored and generated diffs separately, then run the gates below.
-
-Pinned MCP metadata is a sanitized fallback. When a task requires refreshing
-it and a personal session is available, inspect live metadata with `dws auth
-status`, `dws cache refresh`, and `dws schema <canonical> -f json`. Never print
-or commit tokens. Evidence precedence is Runtime/Cobra, live MCP, pinned MCP,
-then Skill prose as evidence only.
-
-## Required checks
-
-```bash
-make generate-schema
-./scripts/policy/check-runtime-confirmation-truth.sh
-./scripts/policy/check-generated-drift.sh
-./scripts/policy/check-schema-catalog.sh
-./scripts/policy/check-command-surface.sh --strict
-make test-schema-agent-examples
-```
-
-Also run focused tests for the changed binder, generator, command, or runtime
-consumer. Run reverse-completeness tests whenever the Cobra tree changes.
-
-Agent examples are contract-checked by default. Eligible reviewed dry-run
-examples are additionally exercised by `make test-schema-agent-examples` with
-isolated state; a runtime failure must not be converted into an ad hoc skip.
-Live-model selection evaluation is optional and never a normal CI dependency.
-
-An example enters runtime dry-run only when its final typed contract publishes
-an explicit reviewed dry-run capability. Risk or confirmation metadata does
-not manufacture preview support, and the harness never injects `--yes`. A
-narrow precondition that cannot be derived from the contract may use an exact,
-reviewed `example_dispositions` entry to narrow dry-run to contract-only; it
-must not become a general skip or a fallback applied after execution fails.
-
-Every `use_when` entry is a positive selection fixture and every `avoid_when`
-entry is a negative fixture for that tool. The deterministic gate checks
-coverage and contradictions; it does not claim to prove natural-language
-understanding. When explicitly requested, the optional live-model smoke test
-can be run with:
-
-```bash
-DWS_AGENT_SELECTION_LIVE=1 \
-ARK_API_KEY=... ARK_BASE_URL=... ARK_MODEL=... \
-go test ./internal/app -run TestManualAgentSelectionArkLive -count=1
-```
-
-Use `DWS_AGENT_SELECTION_FULL=1` for the full fixture or
-`DWS_AGENT_SELECTION_CASES=<comma-separated-ids>` for selected cases. A custom
-HTTPS provider must be explicitly allowlisted; plaintext is accepted only for
-a loopback test server so credentials are not sent over arbitrary clear text.
-
-## Runtime boundaries
-
- `schema list` is a progressive overview; `schema --all` is the complete,
-  non-compact compatibility baseline with full parameters, constraints, and
-  safety semantics.
- `--compact` saves discovery context but is not a full compatibility export.
- `dws <path> --help` decides whether a path and its flags are executable. Leaf
-  Schema owns Agent selection, mapping, constraints, and safety semantics.
- Help and Schema describe commands; they do not return DingTalk business
-  data. Execute the real read/list/search command after discovery.

-# Skill Authoring Guide
-
-Contract for the bundled agent skills under `skills/`. Skills are embedded via
-`skills/embed.go` and installed by `dws skill setup`, so every edit ships with
-the binary. Keep skill prose concise: long command references belong in
-`references/`, not in `SKILL.md`.
-
-## Layout
-
-| Path | Role |
-|---|---|
-| `skills/mono/` | Single bundled skill (stable mode) with shared `references/` and `scripts/` |
-| `skills/multi/dingtalk-<product>/` | One skill per product (experimental mode) |
-| `skills/multi/dws-shared/` | Shared prerequisite: auth, global flags, routing, safety |
-| `skills/embed.go` | Embeds `mono` + `multi`; do not add new roots |
-
-A product skill directory contains:
-
-```text
-dingtalk-<product>/
-  SKILL.md          # frontmatter + concise routing/usage prose
-  references/       # long command references, playbooks
-  scripts/          # executable recipes (python), kept minimal
-```

-## SKILL.md contract

-Frontmatter:
-
-```yaml

-description: <触发场景>. Use when … Distinct from <相邻skill>(…). 命令前缀：dws <product>。
-cli_version: ">=<minimum dws version>"
-metadata:
-  category: product
-  stability: experimental
-  requires:
-    bins:
-      - dws
---
-```
-
-Body rules:
-
- State the safety rules directly in concise prose; there is no injected
-  preamble mechanism in this repository.
- State the `dws-shared` prerequisite for multi skills.
- Route by intent: shortcuts table first when one covers the scenario, then
-  scripts/recipes, then atomic commands with `dws schema` / `--help`.
- Every referenced `dws` command must exist in the current binary; verify with
-  `dws <cmd> --help` and keep prose version-agnostic ("以当前 dws 二进制为准").
- Mutating commands must point at the leaf Schema `confirmation` contract; do
-  not invent confirmation rules in prose.
-
-## Dual-write rule
-
-Skill behavior described in prose must match the CLI it references. When a
-command, flag, or confirmation contract changes, update the affected `SKILL.md`
-/ `references/` in the same change; when skill routing changes, check whether
-Schema selection hints (`internal/cli/schema_hints/`) need a reviewed update
-per [`schema-contributor-guide.md`](schema-contributor-guide.md).
-
-## Validation
-
-| Change | Check |
-|---|---|
-| Any skill edit | `make skill-command-integrity` |
-| Referenced CLI surface changed | `./scripts/policy/check-command-surface.sh --strict` |
-| Schema hints touched | `make generate-schema` + schema gates |
-| Recipe scripts | run the script's own smoke path or `test/skill_e2e` when applicable |
-
-`make skill-command-integrity` builds `scripts/policy/skill-command-check` and
-verifies every `dws` command referenced by skills resolves against the current
-binary. Run it before handoff; do not claim a command exists without it.

-# Schema Runtime and Publication Agent Guide

-This file applies to `internal/cli/`. Read
-[`docs/schema-contributor-guide.md`](../../docs/schema-contributor-guide.md)
-before editing.
-
-## Owning inputs
-
-| Change | Edit |
-|---|---|
-| Canonical identity, primary path, aliases, navigation | `schema_command_registry.json` |
-| Parameter/property mapping | `schema_parameter_bindings.json` or reviewed metadata overlay |
-| Safety, interface, runtime gate | `schema_hints/metadata/<product>.json` |
-| Agent selection and examples | `schema_hints/selection/<product>.json` |
-| Exact reviewed omission | `schema_command_exclusions.json` |
-| Runtime query/projection behavior | Go implementation and focused tests in this package |
-
-The executable Cobra tree outside this package owns whether a command exists
-and which flags it accepts. Do not create a command or flag in Schema inputs.
-
-## Generated boundary
-
- `schema_catalog.json` and `schema_agent_metadata/` are generated outputs.
- Never hand-edit, merge from, or use a previous generated output as an input.
- Change the owning reviewed input or generator, run `make generate-schema`,
-  and inspect authored and generated diffs separately.
- A broad unrelated generated diff is a failure signal, not acceptable churn.
-
-## Self-check
-
- Every public runnable Cobra leaf is bound or has one exact reviewed
-  exclusion; every delivered tool binds back to a runnable leaf.
- Registry identity and native annotations agree; aliases do not mutate the
-  resolved contract.
- Parameters reference real flags and retain Cobra-required floors.
- Selection examples use executable paths/flags and never include `--yes`.
- Runtime confirmation gates and published safety metadata agree.
- Full, compact, summary, alias, and Catalog projections derive from the same
-  typed `ToolSpec` and preserve provenance winners.
-
-Run the focused package/generator tests and the complete command list in
-`docs/schema-contributor-guide.md`, beginning with `make generate-schema`.

-# Product Command Handler Agent Guide
-
-This file applies to `internal/helpers/`. Read the root `AGENTS.md`,
-[`CONTRIBUTING.md`](../../CONTRIBUTING.md), and
-[`docs/coding-agent-guide.md`](../../docs/coding-agent-guide.md) first.
-For package/file layout, read
-[`docs/helpers-structure-guide.md`](../../docs/helpers-structure-guide.md)
-before adding or moving product leaves.
-
-## Scope and routing
-
-`internal/helpers` owns product command construction and handler behavior. Find
-the owning product file and its closest tests before editing.
-
-| Concern | Owning surface |
-|---|---|
-| Root/static command wiring or plugin loading | `internal/app` |
-| Product command flags and handler behavior | `internal/helpers` |
-| Helpers file layout / megafile splits | [`docs/helpers-structure-guide.md`](../../docs/helpers-structure-guide.md) |
-| Shared Cobra construction | `internal/cobracmd` |
-| Invocation and transport | `internal/executor`, `internal/transport` |
-| Structured failures and recovery hints | `internal/errors`, `internal/recovery` |
-| Output encoding and projections | `internal/output` |
-| Confirmation and dry-run guards | `internal/safety` and command runtime gates |
-| Agent identity/Schema/parameters | `internal/cli` and [`docs/schema-contributor-guide.md`](../../docs/schema-contributor-guide.md) |
-
-Do not modify `internal/app` or shared layers merely to register an ordinary
-product leaf when the existing helper construction already owns it. Cross the
-package boundary only when the task changes that shared contract.
-
-## File layout (hard rules)
-
- Stay in flat `package helpers`; do not add `helpers/{product}` subpackages by
-  default.
- Product root `{product}.go` owns `new{Product}Command()` and wires subgroups.
- Put leaves in `{product}_{resource}.go` by CLI resource (see `sheet_*.go`).
- Do not grow megafiles such as `chat.go` or `aitable.go`; extract or add the
-  resource file instead.
- Mechanical splits must be behavior-neutral and keep registration symbols
-  stable. Details and size guides:
-  [`docs/helpers-structure-guide.md`](../../docs/helpers-structure-guide.md).
-
-## Command contract
-
- Confirm the current path and flags with `dws <path> --help` and the Cobra
-  construction before changing behavior.
- Keep stdout machine-readable business data. Send progress, warnings, and
-  diagnostics through the established stderr/logging paths.
- Preserve structured error category, stable exit behavior, cause, trace ID,
-  and an actionable recovery hint. Do not replace a typed lower-layer failure
-  with an unclassified message.
- Treat paths, JSON payloads, filenames, and remote content as untrusted input;
-  use existing validation and sanitization helpers.
- Mutating or destructive commands must keep their preview/confirmation
-  behavior aligned with runtime safety and published Schema metadata.
- If flags, identity, parameters, selection, or safety metadata change, follow
-  the scoped `internal/cli/AGENTS.md` and regenerate from reviewed inputs.
-
-## Verification matrix
-
-| Change | Required focused evidence |
-|---|---|
-| Handler bug or behavior | package regression test including the failure path |
-| Flags or request mapping | Cobra/help test plus dry-run request assertion when the command supports preview |
-| Output or error behavior | structured payload, stderr/stdout, and exit-code assertions |
-| Mutating behavior | preview/confirmation test; live execution only with explicit authorization and disposable data |
-| Shared helper refactor | affected product tests plus `go test ./internal/helpers/...` |
-| Public command surface | Schema/command gates from `internal/cli/AGENTS.md` |
-
-Before handoff, run the narrow package tests, `make format-check`, and the
-admission checks selected by `docs/coding-agent-guide.md`. Do not claim a live
-round-trip when only dry-run or mocked transport was exercised.

修雨	735ef6b3f2	test(markdown): make disappearing-upload-file cases deterministic The three temporary_file_disappears_before_stat subtests raced a polling goroutine against a 16MB write, hoping the removal landed between write and stat. On fast CI runners the window is routinely missed, failing Coverage jobs on main and every open PR. Replace the race with an injectable markdownStatUpload seam that removes the file before delegating to os.Stat.	2026-07-24 11:12:52 +08:00
