Merge remote-tracking branch 'origin/master' into worktree/default-model-persistence

Carries two edits beyond conflict resolution, both forced by what master
brought in:

- `CustomProviderCard`: master added front-end key validation and a
  component-level `keyValue` (already trimmed) while still writing
  `apiKeyEnv` unconditionally. Kept this branch's blank-key rule and its
  committed-profile retry gate, and adopted master's single `keyValue` so
  the component has one spelling of the key rather than two.
- `docs/user/guide/providers`: master merged #1810, whose default-model
  section still taught overriding the `api-gateway` row in
  `$DSH_HOME/config.yaml` — the behavior this branch replaced. Rewritten
  for the settings section the picker now writes, plus the review fix from
  #1810 replacing the colloquial 挂着 in the opener.

File-tool path summaries (`read` / `write` / `edit` args carrying `path` or `file_path`) render as hover-underline links with a pointer cursor. Clicking the path calls `host.openPath` through `WorkspacesService.openPath`, resolving relative paths against the session cwd. File-link rows disable args expand (leading icon is inert); whole-row click, row hover fill, and the click-to-open-details gesture are removed from tool rows (including bash and todo registrations). The details panel and its inject surface remain for programmatic selection; rows no longer drive them.
`host.openPath` is a privileged unary RPC accepted only from loopback, same-origin browser requests (same carrier guard as `host.pickDirectory`).

Platform adapters open without a shell: `open` on macOS, PowerShell `Invoke-Item` on Windows, and `xdg-open` on desktop Linux. WSL is a separate host shape despite Node reporting `linux`: the adapter recognizes its environment or Microsoft kernel release, translates the Linux path with `wslpath -w`, and passes the resulting Windows/UNC path to the same PowerShell handoff. The opener's platform facts and command runner are injectable for tests. URL-only read args (`web_fetch`) are not file links.

- Open files inside an in-app preview — rejected; the ask is the OS default application.

# Agent Note: Guarded-mutation errors append the recovery instruction at the model boundary
Status: implemented
English | [中文](2026-08-03-fs-tool-error-remedy.zh.md)
## Problem
Guarded `write` and `edit` failures reach the model with messages that state the condition but not the only correct recovery: `FS_STALE_VERSION` ("file changed since it was read") and `FS_NOT_OBSERVED` ("edit requires reading … first"). The model must guess that the recovery is a re-read (or a first read) followed by a retry, and the retry/permission/UI layers that route on the structured code see the same message text. The provider-owned messages are part of the storage seam's machine-oriented vocabulary ([filesystem capability seam](../architecture/2026-06-17-filesystem-capability-seam.md)), so the remedy cannot live there without leaking model-facing wording into every consumer of `FsError`.
## Decision
`dsh-tool-fs` owns a model-facing error wrapper, `remediateFsError` in `src/error.ts`, applied in `write.ts` and `edit.ts` after the sandbox denial mapping. It appends the recovery instruction to the two guarded-mutation codes and passes everything else through untouched:
- `FS_STALE_VERSION` (including a missing edit target, which shares the stale code) gains `— re-read the file, then retry`.
- `FS_NOT_OBSERVED` gains `— read the file, then retry`.
The structured `FsError` code is preserved so retry/permission/UI layers keep routing on it, and the original error chains as `cause`. Provider messages stay machine-oriented and unchanged.
In `edit.ts` the `fs/edit-intent` waterfall now sits inside the same `try` as the provider mutation, so the policy plugin's `FS_NOT_OBSERVED` refusal thrown from the intent slot also receives the remedy — both refusal paths reach the model with the same recovery wording.
## Alternatives considered
- **Append the remedy to the provider messages in `dsh-fs` / `dsh-fs-local`.** Rejected because those messages are machine-oriented seam vocabulary consumed by retry, permission, and UI layers as well as the model surface; model-facing wording belongs at the model boundary, where `dsh-tool-fs` already owns result formatting ([filesystem capability seam](../architecture/2026-06-17-filesystem-capability-seam.md)).
- **Add the recovery to prompt guidance instead.** Rejected because the failure arrives mid-task; a static instruction does not reliably reach the retry decision, while the error message is present exactly when the model must act.
- **Signal the remedy with a new `FsError` code.** Rejected because the two failures are the same conditions retry layers already handle; splitting the code would fork routing on identical semantics.
## Consequences
Model-visible text for the two codes changes; the `fs-policy-reject` keyless snapshot is re-recorded, and the READMEs of `dsh-tool-fs` and `dsh-fs-policy` pin the exact appended text. Unit tests cover the wrapper directly (remedy text, code preservation, cause chaining, passthrough of other codes and non-`FsError` values) and the assembled tool paths assert the remedy reaches the model for both codes.
The remedy is not a promise: a deleted observed target cannot be unblocked, because re-reading a missing file fails with `FS_NOT_FOUND` and records no observation. That dead end is pinned fail-closed in the integration tests — the retried mutation fails identically until the target exists again and is freshly observed.

# Agent Note: Guarded-mutation errors append the recovery instruction at the model boundary
Status: implemented
[English](2026-08-03-fs-tool-error-remedy.md) | 中文
## Problem
受防护的 `write` 与 `edit` 失败以只陈述条件、不给出唯一正确恢复方式的消息到达模型:`FS_STALE_VERSION`("file changed since it was read")与 `FS_NOT_OBSERVED`("edit requires reading … first")。模型必须自行猜测恢复方式是重新读取(或首次读取)后重试,而基于结构化错误码路由的重试/权限/UI 层看到的也是同一段消息文本。提供方拥有的消息属于存储接缝的面向机器词汇([filesystem capability seam](../architecture/2026-06-17-filesystem-capability-seam.md)),因此恢复指令不能放在那里,否则会把面向模型的措辞泄漏给 `FsError` 的每个消费者。
## Decision
`dsh-tool-fs` 拥有一个面向模型的错误包装 `remediateFsError`(位于 `src/error.ts`),在 `write.ts` 与 `edit.ts` 中于沙箱拒绝映射之后应用。它为两个受防护变更错误码追加恢复指令,其余错误原样透传:
- `FS_STALE_VERSION`(包括缺失的编辑目标——它与陈旧错误共用同一错误码)追加 `— re-read the file, then retry`。
- `FS_NOT_OBSERVED` 追加 `— read the file, then retry`。
结构化 `FsError` 错误码保持不变,使重试/权限/UI 层继续基于它路由;原始错误作为 `cause` 链入。提供方消息保持面向机器且不变。
在 `edit.ts` 中,`fs/edit-intent` waterfall 现在与提供方变更位于同一个 `try` 内,因此策略插件从 intent 槽抛出的 `FS_NOT_OBSERVED` 拒绝也会获得恢复指令——两条拒绝路径都以相同的恢复措辞到达模型。
## Alternatives considered
- **在 `dsh-fs` / `dsh-fs-local` 的提供方消息中追加恢复指令。** 被拒绝:这些消息是面向机器的接缝词汇,除模型表面外还被重试、权限与 UI 层消费;面向模型的措辞应位于模型边界,即 `dsh-tool-fs` 已经拥有结果格式化之处([filesystem capability seam](../architecture/2026-06-17-filesystem-capability-seam.md))。
- **改为在提示词引导中加入恢复方式。** 被拒绝:失败发生在任务中途;静态指令无法可靠地影响重试决策,而错误消息恰好在模型必须行动时出现。
- **用新的 `FsError` 错误码表达恢复指令。** 被拒绝:这两种失败本就是重试层已处理的相同条件;拆分错误码会让语义相同的路由分叉。
## Consequences
两个错误码的模型可见文本发生变化;`fs-policy-reject` 无密钥快照被重新录制,`dsh-tool-fs` 与 `dsh-fs-policy` 的 README 逐字固定追加后的文本。单元测试直接覆盖包装器(恢复指令文本、错误码保留、cause 链、其他错误码与非 `FsError` 值的透传),组装后的工具路径断言两个错误码的恢复指令都到达模型。
恢复指令不是承诺:已删除的观察目标无法被解除阻塞,因为重新读取缺失文件会以 `FS_NOT_FOUND` 失败且不记录观察。这一死胡同在集成测试中以 fail-closed 方式固定——在目标重新存在并被新鲜观察之前,重试的变更以相同方式失败。
