+# Agent Note: Compaction checkpoints use an English engineering register
+
+Status: implemented
+
+English | [中文](2026-07-31-english-compaction-checkpoints.zh.md)
+
+## Problem
+
+A compaction checkpoint becomes part of the next model request's durable prefix. When a multilingual conversation leads the compactor to preserve its narrative material in the conversation language, the checkpoint can introduce a large amount of a language that is absent from the code, tool output, and existing reasoning prefix. That language then persists across later compaction cycles and can influence the conversation model's reasoning register.
+
+## Decision
+
+`COMPACTION_INSTRUCTION` requires an English-language internal engineering checkpoint. It asks the model to translate narrative source material as needed while preserving exact literals, including paths, commands, errors, identifiers, signatures, and quoted wording when exactness matters. The checkpoint's headings and terse engineering bullets remain the existing structured format.
+
+The requirement is integrated into the first sentence of the trailing compaction instruction. The replayed system prompt, tools, and conversation history remain byte-identical to the routed request, so the change retains the prefix-cache reuse owned by the [compaction summary prefix-cache note](2026-07-21-compaction-summary-prefix-cache-reuse.md).
+
+## Alternatives considered
+
+- **Leave checkpoint language to the replayed conversation** — rejected: the checkpoint is a durable prompt prefix, so preserving a transient conversational register can amplify it across later compactions.
+- **Constrain the conversation model's language** — rejected: the policy is for an internal checkpoint, not the user's visible conversation, and a conversation-wide rule would unnecessarily change normal interaction.
+- **Require ASCII-only output** — rejected: ASCII is a character-set constraint rather than an engineering-register constraint and would unnecessarily distort legitimate literals and technical material.
+- **Append a separate final English-only sentence** — rejected: stating the requirement in the instruction's opening output contract is shorter and ties it directly to the checkpoint being requested.
+
+## Consequences
+
+- New checkpoints normalize narrative context into English while retaining the exact strings that future tool use and code work depend on.
+- Existing checkpoint structure, compaction routing, and cache alignment are unchanged; only the final user instruction is different.
+- The direct summarization call remains outside transcript snapshots because it emits no `assistant/chunk` events. The real-loop regression instead asserts the exact final instruction received by the summarization request.

+# Agent Note: 压缩检查点使用英语工程文体
+
+Status: implemented
+
+[English](2026-07-31-english-compaction-checkpoints.md) | 中文
+
+## 问题
+
+压缩（compaction）检查点会成为下一次模型请求中持久存在的前缀。当多语言对话使压缩器以对话语言保留叙述性材料时，检查点可能引入大量代码、工具输出和既有推理（reasoning）前缀中均未出现的语言内容。该语言随后会在后续压缩周期中持续存在，并影响对话模型的推理文体。
+
+## 决策
+
+`COMPACTION_INSTRUCTION` 要求生成英语的内部工程检查点。它要求模型在必要时翻译叙述性源材料，同时保留精确的字面量；这包括路径、命令、错误、标识符、签名，以及精确性重要时的引用措辞。检查点的标题及简洁的工程项目符号仍沿用既有的结构化格式。
+
+这项要求被整合到尾部压缩指令的第一句话中。回放的系统提示词、工具和对话历史与已路由请求保持字节级一致，因此该变更保留 [compaction summary prefix-cache note](2026-07-21-compaction-summary-prefix-cache-reuse.md) 所确立的前缀缓存复用。
+
+## 考虑过的替代方案
+
+- **让回放的对话决定检查点语言**——不采纳：检查点是持久的提示词前缀，保留短暂的对话文体可能在后续压缩中放大这种影响。
+- **约束对话模型的语言**——不采纳：该策略针对内部检查点，而不是用户可见的对话；对整个对话施加规则会不必要地改变正常交互。
+- **要求仅输出 ASCII**——不采纳：ASCII 是字符集约束，而非工程文体约束，并会不必要地扭曲合法的字面量和技术材料。
+- **在末尾追加一句独立的仅限英语要求**——不采纳：在指令开头的输出契约中说明该要求更简洁，也直接将其与所请求的检查点绑定。
+
+## 后果
+
+- 新检查点会将叙述性上下文规范化为英语，同时保留未来工具使用和代码工作所依赖的精确字符串。
+- 既有检查点结构、压缩路由和缓存对齐保持不变；只有最后一条 user 指令不同。
+- 直接摘要调用仍不纳入 transcript（文本记录）快照，因为它不会发出 `assistant/chunk` 事件。真实循环回归改为断言摘要请求收到的精确最终指令。

The denial marker names the mode at the moment it matters and the escalation fields carry the recovery. The absence decision is superseded by [the current-policy decision](2026-07-30-current-sandbox-policy-context.md); this measurement and causal observation remain the evidence that any replacement must counter-test.

 - A denied command retried with `sandbox_permissions` + `justification` prompts the user through the composed answerer chain; a grant runs THAT call under the wider mode (result facts say so) while every other call keeps its own effective mode; every non-grant outcome produces its distinct error text and executes nothing.
 - The escalation fields exist exactly when the mounted executor confines; a request that is not strictly wider than the call's effective mode fails closed with its own text and prompts no one; a deployment with no ApprovalService fails escalating calls closed and leaves plain calls untouched.
-- The system prompt never states the sandbox mode (an approval `'never'` policy is the one stated knob), and the whole exchange — headers, knob events, notices, approvals, results — reconstructs from the session log alone, with no event types beyond the two knob events.

-- A resumed session's overrides apply with no catch-up state; a default changed while the process was down is narrated before the session's first new request, attributed to the operator.

+# Agent Note: Current sandbox policy context
+
+Status: implemented
+
+English | [中文](2026-07-30-current-sandbox-policy-context.zh.md)
+
+## Problem
+
+The sandbox policy already enforced and logged each session's file-effect mode, but a fresh model request did not contain that state. In a Web session under `read-only`, write and edit schemas remained visible, so the model claimed it could write and learned otherwise only after a denied call. After `/permission danger-full-access`, the next request carried the approval-policy change but still omitted the sandbox mode. Denial results were therefore the first model-visible policy source even when the user asked about capability before any operation.
+
+## Decision
+
+`dsh-sandbox-policy`, the owner of mode and workspace-root resolution, registers one `sandbox:policy` cache-safe context contribution. Every agent request resolves the active session directly through `ctx.sandboxPolicy.resolve({ session })`; there is no denial-history scan or process-local “last told” state.
+
+The policy contribution is capability-neutral and present for every agent session. It does not maintain a second inventory of mounted backends or tools; model-visible schemas remain the authority for available operations, while the context conditions its claims on any available operation that the DSH file sandbox enforces. The [capability-neutral policy context decision](../simplification/2026-07-31-capability-neutral-sandbox-policy-context.md) supersedes the earlier family-registration mechanism while retaining this note's cache-safe delivery and durable snapshot design.
+
+The contribution states only facts shared by every enforcement dialect. `read-only` says an available sandbox-enforced operation cannot modify files in the standing mode and directs the model to try an available tool normally, then follow any denial and escalation guidance that tool returns. `workspace-write` states the canonical session workspace with non-exclusive wording and summarizes, without enumerating, that some platform temporary areas may also be writable. `danger-full-access` says the DSH file sandbox does not restrict file modifications by available operations. Backend-selected temporary paths, `/dev/null`, runner readiness, exact tool availability, and other policy domains are absent because `resolve()` cannot establish them at request assembly.
+
+The existing `dsh-system-prompt` assembly now has ordered dynamic contexts alongside stable system sections and tool schemas. After assembling one step, agent-loop renders all active contexts as one full snapshot with an explicit supersession statement. It appends a sourced `user/message` only when no retained snapshot exists, the bytes changed, compaction removed the retained message, or the final contribution disappeared and needs one clearing snapshot. The snapshot is appended after existing history and before `step/start`, so a changed policy preserves the preceding system-and-conversation cache prefix. The session event itself reconstructs the exact model input; `request/header` remains byte-identical when only policy context changes.
+
+Ownership stays narrow. Approval policy contributes its complete current `ask` or `never` fact to the same full snapshot; migrating sandbox alone would not preserve cache because `/permission` changes both owners. Plan mode remains `plan:policy`, and tool plugins continue to own schemas plus attempt, denial, and escalation guidance. Context states standing policy; filesystem, one-shot bash, and terminal backends remain the enforcement boundaries.
+
+The cache decision follows current source rather than analogy alone. Codex models permissions as a developer-role `WorldState` section with a persisted fingerprint, emits it only when state changes or retained history lost the fragment, and records the snapshot transition. Hermes keeps its system prompt fixed for a session and explicitly prepends changing skill, model, and voice notices to the next user message to avoid invalidating prompt cache. Pi has no comparable built-in sandbox state, and Claude Code's current native implementation is not publicly inspectable; Anthropic's public cache guidance nevertheless places changing per-request context after the stable cached prefix.
+
+The earlier real-provider Web fixture quantified the defect in the system-section version. The first `danger-full-access` and `workspace-write` requests each reported only 256 cache-read tokens against 14,691 and 14,782 uncached input tokens. Later steps under an unchanged policy reported approximately 14.7k–15.5k cache-read tokens. Moving only the sandbox sentence would not fix those misses because the same preset switch also rewrote the approval-policy system section.
+
+## Wording evidence
+
+The wording experiment pre-registered preemptive refusal as its primary endpoint and required the old standing sentence to produce at least one refusal in twelve fresh sessions before any replacement could be judged. On 2026-07-30, commit `2bf41990401b194bd8637f07bbd90c67a9eeac75` ran `deepseek-v4-flash` through the shipped Web composition with the exact positive-control sentence `Bash commands run under the "read-only" file sandbox.` and the current tool-owned attempt guidance. The control produced zero preemptive refusals and zero speculative escalations; all twelve sessions made an ordinary bash call, observed a denial, escalated in the same turn, received approval, and landed the requested file. No sample was excluded.
+
+After the cache-safe delivery change, commit `10d4e0ff7b68d38fc4403403b644aac442b97a00` repeated the same twelve-session positive control through the new tail-context channel. It again produced zero preemptive refusals and zero speculative escalations; all twelve sessions made an ordinary first call, observed denial, escalated in the same turn, and received approval. Eight landed the exact requested file, and no sample was excluded.
+
+Both positive controls therefore failed the pre-registered sensitivity gate. The formal twelve-session Candidate A and B arms were not run, and these experiments do not select or validate the current wording. They establish that the earlier five-of-twelve result is not reproducible under this task and current tool guidance, and that a stronger positive control or different task distribution is required before making model-behavior rate claims. Deterministic tests below establish truthful request construction and replay only.
+
+The cache-safe delivery rework then supplied a separate, non-statistical acceptance comparison over the neutral Web task `Create the relative path policy-neutral.txt ...`; it does not replace the pre-registered twelve-session experiment. Candidate A's categorical read-only statement produced a text refusal with zero tool calls. Candidate B added one composition-conditioned sentence only for enforced families whose tools expose escalation. A fresh real-provider run then issued an ordinary `write`, observed the read-only denial, retried the same operation in the same turn with `sandbox_permissions: "workspace-write"`, received approval, read the file back, and verified the exact contents. It made no speculative escalation. Across the permission switches and four mutation steps, cache reads were 14,848–15,872 tokens while uncached input was 59–306 tokens per request, directly demonstrating the stable-prefix benefit.
+
+## Alternatives considered
+
+**Narrate only mode changes.** Rejected because it leaves a fresh session uninformed and makes the first denied operation the policy-discovery mechanism. It also requires a baseline definition that is unnecessary when current state can be rendered directly.
+
+**Scan denial history or remember the last narrated mode.** Rejected because denial events describe attempted operations, not authoritative current state, while process-local bookkeeping does not survive resume. The owner can fold the durable policy directly on every request.
+
+**Put current policy in a dynamic system section.** Rejected after real provider evidence showed that a first-time permission switch reduced cache reads to 256 tokens while roughly 14.7k input tokens missed. DeepSeek matches complete prefixes; changing the first wire message prevents reuse of the longer system-plus-history prefix.
+
+**Call `agent.inject()` independently from each policy owner.** Rejected because sibling listener order would define model order, separate messages could expose mismatched intermediate snapshots, and every owner would need its own compaction-retention scan. The existing assembly owner can order contributions and materialize one atomic full snapshot.
+
+**A generic runtime-facts package.** Rejected because the existing system-prompt assembly already owns sections, schemas, variables, scope, and the authoritative per-step waterfall. Extending that owner with ordered contexts adds no package or second registry service.
+
+**Repeat tool schemas or plan guidance in the context.** Rejected because those surfaces already have owners and independent lifecycles. Approval current state joins the snapshot only because the same `/permission` switch changes it and leaving its system section would retain the cache defect.
+
+**Keep Candidate A after the cache-safe move.** Rejected by the neutral real-provider task: the model returned a pure text refusal and made no tool call despite the existing bash attempt guidance. The surviving anti-refusal principle states no escalation mechanics itself; it tells the model not to infer impossibility from the standing label, then delegates denial and escalation behavior back to the available tool.
+
+**Keep sandbox mode absent because a standing mode label once caused preemptive refusal.** Rejected because a fresh Web request otherwise exposes mutation tools while withholding their standing policy, producing false capability claims before the first operation. The earlier live measurement remains a required counter-test: five of twelve turns ended without a tool call under `Bash commands run under the "read-only" file sandbox.` The committed tool-owned attempt guidance postdates that measurement, so the replacement is selected through a new positive-control experiment under the current tool contract rather than assuming the old and current conditions match.
+
+**A separate model-context package.** Rejected because the policy owner can resolve current session state directly and the existing assembly service can order it. A new package would add a shallow composition seam and documentation/gate surface around the same request boundary.
+
+**Enumerate writable temporary roots.** Rejected because the backend is selected later at `confine()`: bwrap, Landlock, Seatbelt, and the in-process filesystem fence do not grant one common temporary-path set. Host-specific paths in a standing request would be both unstable and overclaimed.
+
+## Consequences
+
+A model receives the standing file policy before probing a tool, and the next request after `/permission` reflects the committed mode. The stable system prompt no longer changes for sandbox or approval state; a changed full context snapshot is append-only after retained history, and unchanged state adds no message. Older snapshots remain in history but are explicitly superseded by the latest full snapshot. The statement is guidance, not an enforcement guard: runtime safety still comes from filesystem, one-shot bash, and terminal backends consuming the same resolved policy.
+
+Focused tests pin all modes, canonical roots, switch timing, service disposal, context ordering, clearing, stable request headers, resume, and byte stability across different `TMPDIR` values. Keyless assembled snapshots pin the durable context message through real Loader compositions. Keyless replay owns the neutral denial-to-escalation trajectory; it is a structural regression proof, not wording-selection evidence.

+# Agent Note: 当前沙箱策略上下文
+
+Status: implemented
+
+[English](2026-07-30-current-sandbox-policy-context.md) | 中文
+
+## 问题
+
+沙箱策略已经强制执行并记录每个会话的文件操作模式，但新的模型请求并不包含这一状态。在 `read-only` 下的 Web 会话中，write 与 edit schema 仍然可见，因此模型会声称自己能够写入，直到一次被拒绝的调用后才发现事实并非如此。执行 `/permission danger-full-access` 后，下一个请求带有批准策略变更，却仍省略沙箱模式。因此，即使用户在任何操作前询问能力，拒绝结果也是模型可见的首个策略来源。
+
+## 决策
+
+`dsh-sandbox-policy` 负责解析模式与工作区根目录，并注册一项缓存安全的 `sandbox:policy` 上下文贡献。每次 agent（智能体）请求都通过 `ctx.sandboxPolicy.resolve({ session })` 直接解析当前会话；不存在拒绝历史扫描或进程本地的「上次告知」状态。
+
+该策略贡献不依赖具体能力，并存在于每个 agent 会话中。它不会另行维护一份已挂载后端或工具清单；模型可见的 schema 仍是可用操作的权威来源，而上下文会将其声明限定在 DSH 文件沙箱所强制执行的任何可用操作上。[不依赖具体能力的策略上下文决策](../simplification/2026-07-31-capability-neutral-sandbox-policy-context.md)取代了较早的家族注册机制，同时保留本 Agent Note 的缓存安全交付与持久快照设计。
+
+该贡献只说明所有强制执行方言所共有的事实。`read-only` 表明受沙箱强制执行的可用操作在常驻模式下无法修改文件，并指示模型正常尝试可用工具，随后遵循该工具返回的任何拒绝与升权引导。`workspace-write` 用非排他措辞说明规范化的会话工作区，并概述某些平台临时区域可能也可写，而不逐一列举。`danger-full-access` 表明 DSH 文件沙箱不会限制可用操作修改文件。后端选择的临时路径、`/dev/null`、runner 就绪状态、确切的工具可用情况和其他策略领域都不会出现，因为 `resolve()` 无法在请求组装时确定它们。
+
+现有 `dsh-system-prompt` 组装在稳定系统段与工具 schema 之外，还包含有序的动态上下文。组装一个步骤后，agent loop（智能体循环）会将所有活动上下文渲染成一份带显式取代声明的完整快照。仅当不存在保留快照、字节发生变化、压缩（compaction）移除了保留消息，或最后一项贡献消失而需要一份清除快照时，它才会追加一条带来源的 `user/message`。快照追加在现有历史之后、`step/start` 之前，因此策略变化时仍会保留此前的系统与对话缓存前缀。会话事件本身可以重建确切的模型输入；只有策略上下文变化时，`request/header` 仍逐字节相同。
+
+归属范围保持收敛。批准策略会将其完整的当前 `ask` 或 `never` 事实贡献给同一份完整快照；只迁移沙箱无法保留缓存，因为 `/permission` 会同时改变两方。计划模式仍由 `plan:policy` 负责，工具插件也继续负责各自的 schema，以及尝试、拒绝与升级引导。上下文负责说明常驻策略；文件系统、一次性 bash 与终端后端仍是强制执行边界。
+
+缓存决策依据当前源码，而不只依靠类比。Codex 将权限建模为 developer 角色的 `WorldState` 段并保存其指纹；只有状态变化或保留的历史丢失该片段时才发出它，同时记录快照转换。Hermes 在会话期间保持系统提示词不变，并明确将不断变化的 skill（技能）、模型与语音通知前置到下一条用户消息，以免提示词缓存失效。Pi 没有可比的内置沙箱状态，Claude Code 当前的原生实现也无法公开检视；不过，Anthropic 的公开缓存指南仍将不断变化的逐请求上下文放在稳定缓存前缀之后。
+
+先前接入真实提供方的 Web fixture（测试前置数据）量化了系统段版本的缺陷。首次 `danger-full-access` 和 `workspace-write` 请求分别只有 256 个缓存读取 token，而未缓存输入 token 为 14,691 和 14,782 个。相同策略下的后续步骤报告约 14.7k–15.5k 个缓存读取 token。只移动沙箱语句无法修复这些未命中，因为同一次 preset 切换还会改写批准策略系统段。
+
+## 措辞证据
+
+措辞实验预先登记「预防性拒绝」为主要终点，并要求旧常驻句子在十二个 fresh session 中至少产生一次拒绝，之后才能评判任何替代措辞。2026-07-30，commit `2bf41990401b194bd8637f07bbd90c67a9eeac75` 通过已交付的 Web 组合运行 `deepseek-v4-flash`，使用精确的阳性对照句子 `Bash commands run under the "read-only" file sandbox.` 与当前工具归属方的尝试引导。对照组产生零次预防性拒绝和零次推测性升级；十二个会话全部先发起普通 bash 调用、观察到拒绝、在同一轮次升级、获得批准，并让所请求文件实际落盘。没有样本被排除。
+
+缓存安全交付变更后，commit `10d4e0ff7b68d38fc4403403b644aac442b97a00` 通过新的尾部上下文通道重复了同一项十二会话阳性对照。结果再次为零次预防性拒绝和零次推测性升权；十二个会话的首次调用均为普通调用，随后观察到拒绝、在同一轮次升权并获得批准。其中八个会话让所请求文件按确切要求落盘，没有样本被排除。
+
+因此，两项阳性对照均未通过预先登记的灵敏度门槛。Candidate A 与 B 的正式十二会话实验组均未运行，这些实验不选择也不验证当前措辞。它们说明先前十二次中五次的结果无法在本任务与当前工具引导下复现；在声明模型行为率之前，需要更强的阳性对照或不同的任务分布。下述确定性测试只证明请求构造与回放真实一致。
+
+随后，缓存安全交付重做针对中性 Web 任务 `Create the relative path policy-neutral.txt ...` 提供了一次独立的非统计验收对比；它不取代预先登记的十二会话实验。Candidate A 的绝对化只读声明导致模型以纯文本拒绝，工具调用为零。Candidate B 只针对受强制执行、且其工具公开升权能力的家族增加一句按组合条件化的文案。随后一次全新的真实提供方运行先发出普通 `write`，观察到只读拒绝，再在同一轮次用 `sandbox_permissions: "workspace-write"` 重试同一操作，获得批准、读回文件并核验确切内容。它没有进行推测性升权。在权限切换和四个变更步骤中，每个请求的缓存读取为 14,848–15,872 个 token，未缓存输入为 59–306 个 token，直接证明了稳定前缀的收益。
+
+## 曾考虑的替代方案
+
+**仅叙述模式变更。** 不予采用，因为这会让新会话不了解策略，并把首次被拒绝的操作变成策略发现机制。如果可以直接渲染当前状态，也就无需额外定义基线。
+
+**扫描拒绝历史或记住上次叙述的模式。** 不予采用，因为拒绝事件描述的是尝试过的操作，而不是权威的当前状态；进程本地的簿记也无法跨恢复保留。归属方可以在每次请求时直接折叠持久策略。
+
+**把当前策略放入动态系统段。** 不予采用，因为真实提供方证据显示，首次权限切换后缓存读取降至 256 个 token，而约 14.7k 个输入 token 未命中缓存。DeepSeek 匹配完整前缀；改变第一条 wire 消息会阻止复用更长的系统与历史前缀。
+
+**由每个策略归属方独立调用 `agent.inject()`。** 不予采用，因为同级监听器的顺序会决定模型所见顺序，分开的消息可能暴露不匹配的中间快照，并且每个归属方都需要各自扫描压缩后的保留状态。现有组装归属方可以对贡献排序，并具体化一份原子化的完整快照。
+
+**通用运行时事实包。** 不予采用，因为现有系统提示词组装已经拥有段、schema、变量、作用域和权威的逐步骤 waterfall（瀑布式事件）。为该归属方增加有序上下文，无需新增包或第二个注册表服务。
+
+**在上下文中重复工具 schema 或计划引导。** 不予采用，因为这些接口已有各自归属方和独立生命周期。批准的当前状态加入快照，仅仅是因为同一个 `/permission` 切换会改变它，而把它留在系统段会保留缓存缺陷。
+
+**缓存安全迁移后仍保留 Candidate A。** 不予采用，因为中性的真实提供方任务中，尽管已有 bash 尝试引导，模型仍以纯文本拒绝，且没有调用工具。保留下来的反预防性拒绝原则本身不说明任何升权机制；它告诉模型不要从常驻标签推断操作不可能完成，然后把拒绝与升权行为交还给可用工具。
+
+**继续省略沙箱模式，因为常驻模式标签曾引发预防性拒绝。** 不予采用，因为新的 Web 请求否则会暴露变更工具，却隐去这些工具的常驻策略，导致模型在首次操作前错误声称自身能力。先前的线上测量仍是必须执行的反证测试：使用 `Bash commands run under the "read-only" file sandbox.` 时，十二个轮次中有五个没有调用工具。已提交的工具归属方尝试引导晚于该测量，因此应通过当前工具契约下的新阳性对照实验选择替代文案，而不能假设旧条件与当前条件相同。
+
+**独立的模型上下文包。** 不予采用，因为策略归属方可以直接解析当前会话状态，现有组装服务也可以对其排序。新包只会围绕同一个请求边界引入浅层组合 seam 和额外的文档／门禁表面。
+
+**枚举可写临时根目录。** 不予采用，因为后端要到稍后的 `confine()` 才会选定：bwrap、Landlock、Seatbelt 和进程内文件系统围栏并不授予一套共同的临时路径。常驻请求中的主机特定路径既不稳定，也会作出过度承诺。
+
+## 后果
+
+模型在试探工具前就会收到常驻文件策略，且 `/permission` 后的下一个请求会反映已提交的模式。稳定的系统提示词不再随沙箱或批准状态变化；变化后的完整上下文快照会在保留的历史之后仅追加，状态不变时不增加消息。较旧的快照仍保留在历史中，但最新的完整快照会明确取代它们。该声明是引导，而不是强制执行护栏：运行时安全仍来自文件系统、一次性 bash 与终端后端消费同一项解析完成的策略。
+
+聚焦测试固定了所有模式、规范化根目录、切换时机、服务释放、上下文顺序、清除、稳定的请求 header、恢复，以及不同 `TMPDIR` 值下的字节稳定性。无密钥的组装快照通过真实 Loader 组合固定持久上下文消息。无密钥回放负责固定中性的拒绝到升级轨迹；它是结构回归证明，而不是措辞选型证据。

+# Agent Note: Web read card frontend — the read tool's line window renders line-numbered and highlighted
+
+Status: implemented
+
+English | [中文](2026-07-30-web-read-card-frontend.zh.md)
+
+## Problem
+
+The [read backend](2026-07-30-web-read-card.md) added a fourth render-intent card, `card: 'read'`, to `ToolResultView`: a settled read now carries `{ path, lines: [{ number, text }], totalLines, lang? }` onto the conversation snapshot as `resultView`. That data reaches the browser, but the Web client had no consumer for it. Every read row derived from args alone and the details panel flattened the result's content blocks into one `<pre>`, so a read showed as `N: text`-prefixed plain text with no gutter, no syntax highlighting, and no "showing N of M" affordance for a windowed read. The [web terminal card](2026-07-28-web-terminal-card.md) established the pattern for consuming a structured card; the read card follows it, result-side only.
+
+## Decision
+
+`ReadBlock` is a `ui-primitives` component that renders a read result as a line-numbered, optionally syntax-highlighted file view, and both Web render sites for a read consume the read render intent through it: the chat tool row (resident under the summary line) and the details panel's Output section. `ui-conversation/src/client/contract/read-card-model.ts` is the single place that turns the snapshot's `resultView` into the component's props, so the two sites cannot disagree.
+
+**A new `ReadBlock` primitive, not an extension of `CodeBlock`.** `CodeBlock` already does shiki highlighting with a language banner and a copy control, but a read view needs a per-line gutter carrying each line's own file number, which `CodeBlock` renders as a single `<pre>` tree with no per-line structure. Extending `CodeBlock` with an optional gutter would push a read-specific concern (windowed line numbers, a "showing N of M" note, a height cap) onto every markdown fence and every `run_code` body that shares that component. Instead `ReadBlock` reuses the part that is genuinely shared: the shiki grammar singleton in `markdown/highlight.ts`. A new `highlightLines(code, lang)` there tokenizes into shiki's own per-line token arrays (`codeToTokens`) rather than the single-`<pre>` HTML `highlightToHtml` produces, so the block can place one gutter number per line and still color the content through the same `--shiki-*` custom properties on the same grammar allowlist. The height cap and its head/tail expand arithmetic are copied from `TerminalBlock` (`ceil(max/2)` head plus the remaining tail), so a long read and a long command output collapse at the same place. The copy control writes the window's raw text (the lines joined by newlines), never the gutter numbers or the banner.
+
+`readCardModel` is result-side only, mirroring the backend: a read call carries no content until `execute` returns, so the pending call stays a `GenericCallView` (`kind: 'read'`) and this returns null for a running read — the row keeps its args-derived summary until the result arrives. It also returns null for a settled call whose result view is not a read card, including a `card` value this UI version does not know (which arrives over the wire and cannot be trusted to be a compiled variant) and the read tool's own generic fallback for an error result. The card's banner label is the read view's `title` when the tool supplied one (the contract's replacement-title rule), otherwise the file path relativized to the session workspace so a workspace-rooted absolute path shows the same short form the row summary shows. The model copies the frozen line array into the primitive's own line shape, so the card never holds a reference into the runtime's snapshot cache.
+
+The chat row renders the card **resident** under the summary line, capped at `CHAT_READ_MAX_LINES` (8, half the primitive's default), the same posture `BashRow` gives a terminal card — the block's internal expander keeps a long read from taking over the message flow. Two render sites carry it: the keyed `ReadRow` (registered under `read` in `apply.ts`, the load-order seam being `inject: ['slots', 'conversation']` exactly as the bash sample) whose summary is the file path as an openable host link, and `GenericToolCard`'s fallback for a read-declaring tool without its own keyed row (e.g. `web_fetch`, which classifies to the `read` variant). The details panel renders the same card at the primitive's own full-height cap (16), because the panel is the single-call reading surface.
+
+Whole-row collapse/expand (defaulting every tool call to collapsed) is a separate later change that will flip every resident card at once; this note's card is resident, matching the terminal card it sits beside.
+
+**Read-card grammars load lazily; only the boot three stay eager.** `highlight.ts` is a platform seed `ui-primitives` loads on every Web boot, and its warm-up unconditionally builds the shiki singleton. The read card's `langFromPath` hints span the full source/config/markup extension set (python, rust, yaml, html, …); registering all of them eagerly would add ~1.6 MB of grammar modules to the boot chunk and their synchronous init to every session, including sessions that never open a read card. So only the three grammars every session already renders — TypeScript, shell, JSON (the markdown-fence and `run_code` languages) — load at boot. Each read-card extension grammar sits behind a dynamic `import()` in `LAZY_GRAMMARS`, keyed by the grammar id its aliases resolve to. On the first `highlightLines`/`highlightToHtml` call for a lazy language, `ensureGrammar` starts the import (once) and returns not-ready, so the card renders plain that frame; when the import resolves it registers the grammar with `loadLanguageSync`, bumps a load counter, and notifies subscribers. `ReadBlock` and `CodeBlock` subscribe through `useSyncExternalStore(subscribeGrammarLoaded, grammarLoadCount)`, so the card re-renders with highlighting the moment the grammar is ready. An unknown/absent language still returns undefined synchronously (plain, never an error).
+
+**The empty-window copy control is hidden, matching `TerminalBlock`.** A successful read of an empty file returns `lines: []`, `totalLines: 0`, and `presentResult` still projects `card: 'read'`, so the empty-window branch is reachable — the read card is not, as an earlier draft assumed, unreachable for an empty result. `ReadBlock` therefore hides the copy control when `lines` is empty, exactly as `TerminalBlock` hides copy on empty output, so the button can never wipe the clipboard with an empty string.
+
+## Alternatives considered
+
+**Extend `CodeBlock` with an optional line-number gutter and `startLine`.** Rejected: it imposes a read-specific gutter, a windowed-count note, and a height cap on every markdown fence and `run_code` body that shares `CodeBlock`, for no benefit to those callers. The genuinely shared surface is the shiki grammar singleton, which both blocks reuse through `highlight.ts`; the chrome around it differs (a read has a gutter and a window note, a fence has neither), so a second small primitive is the correct split, exactly as `TerminalBlock` is a second primitive over the same tokens rather than a `CodeBlock` mode.
+
+**Reuse `highlightToHtml` and inject gutter numbers with CSS counters.** Rejected: the single-`<pre>` HTML shiki emits has no per-line boundary a gutter can hang a file line number off (a windowed read's numbers start above 1 and are not a simple CSS counter increment), and parsing the numbers back out of the HTML would be fragile. `codeToTokens` gives the per-line token structure directly.
+
+**Register all read-card grammars eagerly in the boot warm-up.** Rejected: it puts ~1.6 MB of grammar modules and their synchronous init on every Web boot for a card most sessions never open. The lazy path costs a single plain-first frame the first time a given language is read, then highlights on the grammar-load re-render; the boot cost is paid only for the three grammars every session already renders.
+
+## Consequences
+
+`ui-primitives` gains `ReadBlock` and `highlightLines`; no new runtime dependency (shiki was already present for `CodeBlock`). `ReadBlock` reads only the read view's fields, so it stays a pure function of what the render intent carries — no session lookups, replay-safe like the presenters that produce the view. A UI without the read capability still gets the backend's `content` fallback (the envelope-stripped text) through the generic card, unchanged.
+
+A read row in the Web chat now carries the file content resident, a deliberate density increase over a summary-only row, bounded by the chat cap. A `run_code` sub-dispatch does not reach a read card on the shipped wire for the same reason a nested bash call does not reach a terminal card: `session.ts` folds `tool/code-dispatch(-start)` with `resultView: null`, so a nested read keeps the generic flattened form.
+
+## Testing
+
+`packages/client/ui-primitives/tests/read-block.spec.tsx` pins the primitive and the token path: `highlightLines`' per-line css-variables runs, its trailing-terminator-line drop and the genuinely-blank-final-line case, its `undefined` for an unknown/absent language, and its lazy path (a lazy grammar returns plain on first touch, then highlights after the import registers and the subscriber fires); and `ReadBlock`'s gutter-numbered rows keeping the file's own numbers, the highlighted-vs-plain content arms, the banner (label, language, the count note only when the read is a window), the head/tail height cap with its `aria-expanded` toggle, the copy control writing the window's raw text on both the accepted and refused clipboard paths, and the empty-window arm hiding the copy control. `code-block.spec.tsx` covers `highlightToHtml` including its lazy path over every read-card grammar (each dynamic import thunk touched once). Both `ReadBlock.tsx` and `highlight.ts` (and `CodeBlock.tsx`) hold per-file 100% coverage across the two specs.
+
+`packages/client/ui-conversation/tests/read-card.spec.tsx` pins the wiring at every render site: `readCardModel`'s derivation and each null arm (running read, no view, generic view, unknown card), the result title replacing the relativized path, the path relativization against the workspace, the copy-not-alias of the frozen line array; the resident card in `GenericToolCard`'s fallback and in the keyed `ReadRow` (plus its path link opening the host, its running/error/stopped states, and its `read`-key registration); and the panel's Output section rendering the read card at full height while keeping the JSON Input section, with the running-read placeholder and non-read flattened-pre arms. That file sits on the coverage `exclude` list (`ui-conversation/src/*`), so it is written against no gate pressure.
+
+The fixture (`packages/client/connection/src/client/fixture.ts`) gains turn 66, a `read` call whose result view is a windowed read (lines starting at file line 41, `totalLines` 180, a `ts` hint), so the built-boot snapshot and a live `?fixture` server show the read card with its gutter numbers, highlighting, and count note. It is named `read` to exercise the keyed `ReadRow`. The turn 64 `run_code` sample's nested read sub-dispatches do not exercise the render-site fallback read card: `session.ts` folds them with `resultView: null`, so they cover only the fallback row's generic row shape, not a read card inside it; the fallback-row read card is pinned by `read-card.spec.tsx`'s `web_fetch` case. Turn 66 is ordered before the todo turn (now 67) for the same reason the terminal sample is: the standing plan retires at the next `turn/start`.

+# Agent Note: Web 读取卡片前端 —— 读取工具的行窗口以带行号、语法高亮的形式渲染
+
+Status: implemented
+
+[English](2026-07-30-web-read-card-frontend.md) | 中文
+
+## Problem
+
+[读取后端](2026-07-30-web-read-card.md)给 `ToolResultView` 增加了第四种渲染意图卡片 `card: 'read'`：一次已结算的读取现在会把 `{ path, lines: [{ number, text }], totalLines, lang? }` 作为 `resultView` 带到会话快照上。这份数据能到达浏览器，但 Web 客户端没有消费者。每个读取行都仅从参数派生，详情面板把结果的 content block 摊平进一个 `<pre>`，于是读取显示为带 `N: text` 前缀的纯文本，没有行号栏、没有语法高亮，也没有窗口读取的"显示 N / M"提示。[web 终端卡片](2026-07-28-web-terminal-card.md)确立了消费一个结构化卡片的模式；读取卡片沿用它，只在结果侧。
+
+## Decision
+
+`ReadBlock` 是一个 `ui-primitives` 组件，把一次读取结果渲染成带行号、可选语法高亮的文件视图，读取的两个 Web 渲染点都通过它消费读取渲染意图：聊天工具行（常驻在摘要行之下）与详情面板的 Output 区段。`ui-conversation/src/client/contract/read-card-model.ts` 是把快照的 `resultView` 转成组件 props 的唯一位置，因此两个渲染点不会产生分歧。
+
+**新建一个 `ReadBlock` primitive，而不是扩展 `CodeBlock`。** `CodeBlock` 已经带语言横幅和复制控件做 shiki 高亮，但读取视图需要一个每行带该行自身文件行号的行号栏，而 `CodeBlock` 把内容渲染为单个 `<pre>` 树、没有逐行结构。给 `CodeBlock` 加一个可选行号栏会把读取专属的关切（窗口行号、"显示 N / M"提示、高度上限）强加给共享该组件的每个 markdown 代码围栏和每个 `run_code` 程序体。`ReadBlock` 转而复用真正共享的部分：`markdown/highlight.ts` 里的 shiki 语法单例。那里新增的 `highlightLines(code, lang)` 把代码切成 shiki 自己的逐行 token 数组（`codeToTokens`），而不是 `highlightToHtml` 产出的单 `<pre>` HTML，于是该 block 能每行放一个行号、同时用同一套 `--shiki-*` 自定义属性、同一份语法白名单给内容上色。高度上限及其头/尾展开算法照抄自 `TerminalBlock`（`ceil(max/2)` 行头部加剩余的尾部），因此长读取和长命令输出在同一处折叠。复制控件写入窗口的原始文本（各行以换行拼接），绝不含行号栏或横幅。
+
+`readCardModel` 只在结果侧，与后端对称：一次读取调用在 `execute` 返回前不带任何内容，因此挂起中的调用保持为 `GenericCallView`（`kind: 'read'`），本函数对运行中的读取返回 null —— 该行保持其从参数派生的摘要，直到结果到达。它对结果视图不是读取卡片的已结算调用也返回 null，包括本 UI 版本不认识的 `card` 值（它从线路到来、不能被信任为一个已编译的变体）以及读取工具对错误结果自己的通用回退。卡片横幅标签在工具提供 `title` 时取它（契约的替换标题规则），否则取相对于会话工作区化简后的文件路径，使工作区根下的绝对路径显示为与行摘要相同的短形式。该 model 把冻结的行数组复制进 primitive 自己的行形状，因此卡片绝不持有指向运行时快照缓存的引用。
+
+聊天行把卡片**常驻**渲染在摘要行之下，上限 `CHAT_READ_MAX_LINES`（8，是 primitive 默认值的一半），与 `BashRow` 对终端卡片的姿态相同 —— block 的内部展开器让长读取不会占据整个消息流。两个渲染点承载它：keyed `ReadRow`（在 `apply.ts` 里以 `read` 键注册，加载顺序接缝为 `inject: ['slots', 'conversation']`，与 bash 样例完全一致），其摘要是作为可打开的宿主链接的文件路径；以及 `GenericToolCard` 对没有自己 keyed 行的读取声明工具（例如归到 `read` 变体的 `web_fetch`）的回退。详情面板以 primitive 自己的全高上限（16）渲染同一张卡片，因为面板是单次调用的阅读界面。
+
+整行折叠/展开（把每个工具调用默认折叠）是一个单独的后续改动，它会一次性翻转每张常驻卡片；本 note 的卡片是常驻的，与它旁边的终端卡片一致。
+
+**读取卡片的语法按需 lazy 加载，只有 boot 三种保持 eager。** `highlight.ts` 是 `ui-primitives` 在每次 Web 启动都加载的平台 seed，其预热会无条件构建 shiki 单例。读取卡片的 `langFromPath` 提示覆盖完整的源码/配置/标记扩展集（python、rust、yaml、html……）；把它们全部 eager 注册会给启动 chunk 增加约 1.6 MB 的语法模块、并把它们的同步初始化摊给每个会话，包括从不打开读取卡片的会话。因此只有每个会话本就渲染的三种语法 —— TypeScript、shell、JSON（markdown 围栏与 `run_code` 语言）—— 在 boot 时加载。每种读取卡片扩展语法置于 `LAZY_GRAMMARS` 中一个动态 `import()` 之后，以其别名解析到的语法 id 为键。对某个 lazy 语言首次调用 `highlightLines`/`highlightToHtml` 时，`ensureGrammar` 启动 import（仅一次）并返回未就绪，于是卡片该帧渲染纯文本；import 解析后用 `loadLanguageSync` 注册该语法、递增一个加载计数、并通知订阅者。`ReadBlock` 与 `CodeBlock` 通过 `useSyncExternalStore(subscribeGrammarLoaded, grammarLoadCount)` 订阅，因此语法就绪的那一刻卡片就重渲染带上高亮。未知/缺省语言仍同步返回 undefined（纯文本，绝不报错）。
+
+**空窗口的复制控件被隐藏，与 `TerminalBlock` 对齐。** 成功读取一个空文件会返回 `lines: []`、`totalLines: 0`，且 `presentResult` 仍投出 `card: 'read'`，因此空窗口分支是可达的 —— 读取卡片并非如早前草稿所假设的对空结果不可达。故 `ReadBlock` 在 `lines` 为空时隐藏复制控件，正如 `TerminalBlock` 对空输出隐藏复制，使按钮绝不会用空字符串清空剪贴板。
+
+## Alternatives considered
+
+**给 `CodeBlock` 加一个可选行号栏和 `startLine`。** 拒绝：这会把读取专属的行号栏、窗口计数提示和高度上限强加给共享 `CodeBlock` 的每个 markdown 围栏和 `run_code` 程序体，对那些调用者毫无好处。真正共享的界面是 shiki 语法单例，两个 block 都通过 `highlight.ts` 复用它；围绕它的外壳各不相同（读取有行号栏和窗口提示，围栏两者都没有），因此第二个小 primitive 是正确的切分 —— 正如 `TerminalBlock` 是基于同一套 token 的第二个 primitive，而不是 `CodeBlock` 的一种模式。
+
+**复用 `highlightToHtml`，用 CSS counter 注入行号。** 拒绝：shiki 产出的单 `<pre>` HTML 没有可供行号栏挂上文件行号的逐行边界（窗口读取的行号从大于 1 处开始，不是简单的 CSS counter 自增），而从 HTML 里把行号解析回来又很脆弱。`codeToTokens` 直接给出逐行 token 结构。
+
+**在 boot 预热里 eager 注册所有读取卡片语法。** 拒绝：这会给每次 Web 启动摊上约 1.6 MB 语法模块及其同步初始化，只为一张多数会话从不打开的卡片。lazy 路径的代价是某个语言首次被读取时的一帧纯文本，随后在语法加载的重渲染里高亮；boot 代价只为每个会话本就渲染的三种语法付出。
+
+## Consequences
+
+`ui-primitives` 增加 `ReadBlock` 和 `highlightLines`；没有新的运行时依赖（shiki 已因 `CodeBlock` 存在）。`ReadBlock` 只读取读取视图的字段，因此保持为渲染意图所承载内容的纯函数 —— 无会话查询，与产出该视图的 presenter 一样可安全回放。没有读取能力的 UI 仍通过通用卡片拿到后端的 `content` 回退（剥掉外壳的文本），保持不变。
+
+Web 聊天里的读取行现在常驻承载文件内容，是相对纯摘要行的一次刻意的密度增加，受聊天上限约束。`run_code` 子派发在已发布的线路上到不了读取卡片，与嵌套 bash 调用到不了终端卡片同因：`session.ts` 把 `tool/code-dispatch(-start)` 折叠为 `resultView: null`，因此嵌套读取保持通用的摊平形式。
+
+## Testing
+
+`packages/client/ui-primitives/tests/read-block.spec.tsx` 固定 primitive 与 token 路径：`highlightLines` 的逐行 css-variables 运行、它对尾部终止行的丢弃与真正空白末行的情形、它对未知/缺省语言返回 `undefined`、以及它的 lazy 路径（lazy 语法首次触碰返回纯文本，import 注册且订阅者触发后再高亮）；还有 `ReadBlock` 的带行号行保留文件自身编号、高亮与纯文本两条内容分支、横幅（标签、语言、仅当读取是窗口时的计数提示）、头/尾高度上限及其 `aria-expanded` 切换、复制控件在接受与拒绝两条剪贴板路径上写入窗口原始文本、以及空窗口分支隐藏复制控件。`code-block.spec.tsx` 覆盖 `highlightToHtml`，含它对每种读取卡片语法的 lazy 路径（每个动态 import thunk 各触碰一次）。`ReadBlock.tsx`、`highlight.ts`（及 `CodeBlock.tsx`）在这两个 spec 上均保持每文件 100% 覆盖。
+
+`packages/client/ui-conversation/tests/read-card.spec.tsx` 固定每个渲染点的接线：`readCardModel` 的派生与每条 null 分支（运行中读取、无视图、通用视图、未知卡片）、结果标题替换化简后的路径、路径相对工作区的化简、冻结行数组的复制而非别名；`GenericToolCard` 回退中与 keyed `ReadRow` 中的常驻卡片（外加其路径链接打开宿主、其 running/error/stopped 状态、以及其 `read` 键注册）；还有面板 Output 区段以全高渲染读取卡片同时保留 JSON Input 区段，含运行中读取占位与非读取摊平 pre 两条分支。该文件位于覆盖 `exclude` 列表（`ui-conversation/src/*`），因此不承受门槛压力。
+
+fixture（`packages/client/connection/src/client/fixture.ts`）增加 turn 66，一次 `read` 调用，其结果视图是窗口读取（行号从文件行 41 起、`totalLines` 180、`ts` 提示），使内置启动快照和实时 `?fixture` 服务器展示带行号、高亮和计数提示的读取卡片。它命名为 `read` 以驱动 keyed `ReadRow`。turn 64 的 `run_code` 样例中的嵌套读取子派发并不驱动渲染点回退读取卡片：`session.ts` 把它们折叠为 `resultView: null`，因此它们只覆盖回退行的通用行形状，而非回退行内的读取卡片；回退行读取卡片由 `read-card.spec.tsx` 的 `web_fetch` 用例钉住。turn 66 排在 todo turn（现为 67）之前，与终端样例同因：常驻计划在下一次 `turn/start` 退场。

+# Agent Note: Default Web search in the Web/headless composition
+
+Status: implemented
+
+English | [中文](2026-07-31-web-default-search.zh.md)
+
+## Problem
+
+The harness had a complete Web capability family—provider registry, DeepSeek/Exa/Perplexity search providers, local fetch, stable model tools, and structured result presentation—but the shipped `dsh web` composition mounted none of it. The model could not discover current information unless a deployment supplied a custom overlay. Merely mounting the existing DeepSeek provider would not complete the WebUI path: the Models page stores `DEEPSEEK_API_KEY` through `ctx.credentials`, while the search provider froze only the process environment at plugin load, so a key entered or rotated in the running UI would not reach search.
+
+## Decision
+
+`apps/cli/config/web.cordis.yml` explicitly mounts `dsh-web` with `searchProvider: deepseek-official`, `dsh-web-search-deepseek`, and `dsh-tool-web` with `fetch: false`. It does not mount `dsh-web-fetch-local` or select a fetch provider. The shared overlay makes only `web_search` a default for browser and headless sessions; the TUI composition remains unchanged. The explicit search provider id keeps selection independent of registration order and leaves personal or `--config` overlays able to replace or disable the rows.
+
+DeepSeek search uses the same `DEEPSEEK_API_KEY` credential reference as the official conversation adapter. The provider resolves that reference inside every search through the optional `ctx.credentials` service; only a composition without the seam falls back to the launching process environment, and a non-empty literal `apiKey` remains the programmatic last resort. A stored or rotated Web Models key therefore reaches the next search without restarting or retaining the value on the provider. Because `WebSearchProvider.available()` is synchronous, it treats an installed resolver as locally usable and missing dynamic credentials fail the operation with the provider-specific `WEB_PROVIDER_CREDENTIAL_MISSING` code while the stable tool schema stays registered.
+
+Search keeps its endpoint distinct from chat completions: `DEEPSEEK_SEARCH_BASE_URL` overrides the Anthropic-compatible base, while `DEEPSEEK_BASE_URL` continues to configure conversation requests. Each `web_search` performs an auxiliary DeepSeek Messages call with the native search server tool. Immediately before dispatch, the provider appends a log-only `web/deepseek-search-llm-request` event to the initiating Agent session with the resolved endpoint, API version, and exact secret-free JSON body. Credential preflight remains provider-local and races caller cancellation; neither concern expands the generic Web or credentials seams.
+
+The default mount does not create a Web-specific permission policy. `web_search` executes outside the bash/filesystem sandbox and approval presets, following `dsh-tool-web`'s existing contract. It does not mount `web_fetch` or a local fetch provider, so the default does not grant model-selected arbitrary URL retrieval. The shipped deployment already defaults to `danger-full-access`; a future restricted-network product stance must add a `tools/pre-execute` policy or capability-specific network confinement rather than implying that filesystem access mode governs Web calls.
+
+## Alternatives considered
+
+**Mount only `dsh-tool-web`.** Rejected because stable schemas without registered providers would make every default call fail; enablement and backend availability are deliberately separate, but a shipped default must supply its intended implementations.
+
+**Read `$DSH_HOME/.env` from `cordis.yml` or hoist it into `process.env`.** Rejected because the credential provider owns that document, environment values are read-only overrides, and hoisting would make stored keys unrotatable while bypassing the audited secret boundary.
+
+**Freeze `process.env.DEEPSEEK_API_KEY` at provider load.** Rejected because the Web Models page writes through `ctx.credentials`; the product's documented first-run path must make the next operation work without a restart.
+
+**Mount Web tools in `base.cordis.yml`.** Rejected because that would also change the TUI deployment. The browser and headless entries already share `web.cordis.yml`; they gain the capability together while TUI remains an explicit later decision.
+
+**Enable search and fetch together.** Rejected because default `web_fetch` would allow model-selected anonymous outbound HTTP(S) retrieval to arbitrary URLs. Search covers discovery; deployments that accept broader retrieval can opt into `dsh-web-fetch-local` and set `dsh-tool-web`'s `fetch` option to `true` in their overlay.
+
+## Consequences
+
+Web/headless model requests carry only the `web_search` schema and search-only prompt guidance in native mode; Code Mode exposes the same search capability beneath `run_code`. The prompt tells the model to use returned snippets and never advertises the disabled `web_fetch` tool. Search adds a complete auxiliary model call and may use the native server tool multiple times; its exact secret-free request remains reconstructable from the initiating session log. The default offers search-result snippets and source metadata but no arbitrary page retrieval; deployments that need full-page fetch must opt in. The Web snapshot lane boots the shipped tree, drives a replayed `web_search` call through the real DeepSeek provider against a local Messages fixture, asserts the durable auxiliary request and structured result, and pins the settled browser presentation. The real-composition smoke test pins the absence of `web_fetch`; provider tests pin missing, stored, and rotated credential behavior plus literal and ambient compatibility.

+# Agent Note: Web／无头组合中的默认 Web 搜索
+
+Status: implemented
+
+[English](2026-07-31-web-default-search.md) | 中文
+
+## 问题
+
+该 harness 已具备完整的 Web 能力体系：提供方注册表、DeepSeek、Exa 和 Perplexity 搜索提供方、本地抓取、稳定的面向模型工具，以及结构化结果呈现，但已交付的 `dsh web` 组合没有挂载其中任何一项。除非部署提供自定义覆盖层，否则模型无法发现最新信息。仅挂载现有 DeepSeek 提供方仍无法打通 WebUI 链路：Models 页面通过 `ctx.credentials` 存储 `DEEPSEEK_API_KEY`，而搜索提供方只会在插件加载时固定读取进程环境，因此在运行中的 UI 输入或轮换的密钥无法用于搜索。
+
+## 决策
+
+`apps/cli/config/web.cordis.yml` 明确挂载 `dsh-web`，配置 `searchProvider: deepseek-official`，同时挂载 `dsh-web-search-deepseek`，并以 `fetch: false` 挂载 `dsh-tool-web`。它不挂载 `dsh-web-fetch-local`，也不选择抓取提供方。共享覆盖层只将 `web_search` 设为浏览器与无头会话的默认工具；TUI 组合保持不变。显式搜索提供方 id 使选择不受注册顺序影响，同时个人覆盖层或 `--config` 覆盖层仍可替换或禁用这些配置项。
+
+DeepSeek 搜索使用与官方会话适配器相同的 `DEEPSEEK_API_KEY` 凭据引用。提供方在每次搜索内部通过可选的 `ctx.credentials` 服务解析该引用；只有未挂载该 seam 的组合才会回退到启动进程的环境变量，非空的 `apiKey` 字面值仍作为程序化配置的最后兜底。因此，由 Web 的 Models 页存储或轮换的密钥无需重启即可用于下一次搜索，提供方也无需保留该值。由于 `WebSearchProvider.available()` 是同步方法，它会将已安装解析器视为本地可用；若动态凭据缺失，操作会以提供方专属错误码 `WEB_PROVIDER_CREDENTIAL_MISSING` 失败，而稳定的工具 schema 仍保持注册。
+
+搜索端点与 chat completions 保持独立：`DEEPSEEK_SEARCH_BASE_URL` 覆盖 Anthropic 兼容基址，`DEEPSEEK_BASE_URL` 则继续配置会话请求。每次 `web_search` 都会发起一次辅助 DeepSeek Messages 调用，并携带原生搜索服务器工具。发出请求前一刻，提供方会向发起请求的 agent（智能体）会话追加仅用于日志的 LLM（大语言模型）请求事件 `web/deepseek-search-llm-request`，其中包含已解析端点、API 版本，以及不含密钥的精确 JSON 请求体。凭据预检仍留在提供方内部，并与调用方取消存在竞态；这两项关注点都不会扩展通用 Web seam 或凭据 seam。
+
+默认挂载不会创建 Web 专用权限策略。`web_search` 在 bash／文件系统沙箱及审批预设之外执行，并遵循 `dsh-tool-web` 的现有契约。组合不挂载 `web_fetch` 或本地抓取提供方，因此默认配置不会允许模型自行选择任意 URL 进行抓取。已交付部署的默认值本就是 `danger-full-access`；未来如果产品采取受限网络策略，必须添加 `tools/pre-execute` 策略或按能力限制网络访问，而不能暗示文件系统访问模式会管辖 Web 调用。
+
+## 考虑过的替代方案
+
+**仅挂载 `dsh-tool-web`。** 不予采纳：稳定的 schema 如果没有已注册提供方，每次默认调用都会失败。启用状态与后端可用性刻意分离，但已交付的默认配置必须提供其预期实现。
+
+**从 `cordis.yml` 读取 `$DSH_HOME/.env`，或将其提升到 `process.env`。** 不予采纳：凭据提供方拥有该文件，环境变量值是只读覆盖；提升后存储的密钥将无法轮换，还会绕过经审计的密钥边界。
+
+**在提供方加载时固定读取 `process.env.DEEPSEEK_API_KEY`。** 不予采纳：Web Models 页面通过 `ctx.credentials` 写入密钥；产品文档规定的首次运行路径必须保证下一次操作无需重启即可生效。
+
+**在 `base.cordis.yml` 中挂载 Web 工具。** 不予采纳：这也会改变 TUI 部署。浏览器与无头入口已经共享 `web.cordis.yml`；两者会一同获得该能力，是否为 TUI 启用则仍留作后续显式决策。
+
+**同时启用搜索和抓取。** 不予采纳：默认启用 `web_fetch` 会允许模型自行选择任意 URL，执行匿名出站 HTTP(S) 抓取。搜索负责发现信息；接受更广泛抓取范围的部署可以在覆盖层中选择启用 `dsh-web-fetch-local`，并将 `dsh-tool-web` 的 `fetch` 选项设为 `true`。
+
+## 后果
+
+Web／无头模型请求在原生模式下只会携带 `web_search` schema，以及仅用于搜索的提示词指引；Code Mode 通过 `run_code` 公开相同的搜索能力。该提示词要求模型使用返回的 snippet，且绝不会向模型提及已禁用的 `web_fetch` 工具。搜索会增加一次完整的辅助模型调用，并可能多次使用原生服务器工具；发起会话的日志仍可精确重建其不含密钥的请求。默认配置会提供搜索结果 snippet 与来源元数据，但不支持任意页面抓取；需要抓取完整页面的部署必须自行选择启用抓取。Web 快照通道会启动已交付配置树，使用本地 Messages fixture（测试前置数据），经由真实 DeepSeek 提供方驱动一次回放的 `web_search` 调用，断言持久化的辅助请求与结构化结果，并固定最终浏览器呈现。真实组合冒烟测试固定了不提供 `web_fetch` 这一事实；提供方测试固定缺失、已存储及已轮换凭据的行为，以及字面值与环境变量的兼容性。

+# Agent Note: Capability-neutral sandbox policy context
+
+Status: implemented
+
+English | [中文](2026-07-31-capability-neutral-sandbox-policy-context.zh.md)
+
+## Problem
+
+The current-policy context originally mirrored runtime composition through separate enforced-family and escalatable-family registries. Six backend, tool, and example call sites contributed `filesystem`, `bash`, or `terminal`; the policy service retained token sets for independent disposal, intersected and ordered the two registries, invalidated prompt assemblies on every lifecycle change, and tested every family combination.
+
+That inventory was neither needed to state the file policy nor authoritative for model-visible capability. A backend contribution could name a family whose model-facing tool was absent or hidden by request scope, while tool schemas already told the model which exact operations were available. The registries therefore widened the public service and lifecycle contract to maintain an approximate English sentence.
+
+## Decision
+
+`dsh-sandbox-policy` contributes one capability-neutral `sandbox:policy` context for every agent session. It derives the text only from `resolve({ session })`; there is no backend or tool family registration API, contribution map, ordering rule, or registration-driven prompt invalidation.
+
+The text conditions capability claims on available operations that the DSH file sandbox enforces. Under `read-only`, it states that such operations cannot modify files in the standing mode and tells the model to try an available tool normally, then follow any denial and escalation guidance that tool returns. Under `workspace-write`, it states the canonical session workspace and the qualified temporary-area allowance. Under `danger-full-access`, it states that the DSH file sandbox does not restrict file modifications by available operations.
+
+Tool schemas remain the authority for which operations are available. Tool results remain the authority for operation-specific denials and approved wider retries. Filesystem, one-shot bash, and terminal implementations continue to resolve and enforce the same per-call policy; only the redundant model-facing capability inventory is removed.
+
+This decision partially supersedes the family-registration and composition-conditioned wording in [the current sandbox policy context decision](../feature/2026-07-30-current-sandbox-policy-context.md). That note remains the owner of cache-safe context delivery, durable snapshot materialization, wording evidence, and the separation between guidance and enforcement.
+
+## Alternatives considered
+
+**Keep the registries but reduce their tests.** Rejected because the public methods, retained lifecycle state, six contribution sites, and approximate capability claim would remain. The combinatorial tests reflected the design cost; they did not create it.
+
+**Derive an exact inventory from the tool registry.** Rejected because current policy needs only a truthful conditional statement, while exact availability already appears in the assembled tool schemas and can vary by request scope. Mapping each schema back to an enforcement backend would introduce another derived relation with no current consumer.
+
+**Omit policy context unless a backend advertises enforcement.** Rejected because it recreates the registration problem and makes policy visibility depend on optional contributors. The conditional wording remains truthful even when no applicable operation is available.
+
+## Consequences
+
+The policy service has one owner-derived context path instead of two public registries and their disposal lifecycle. Capability additions and removals no longer churn the runtime-context snapshot, while mode and workspace changes still do. Exact mode wording, canonical roots, switching, resume, service disposal, and no-agent assembly remain covered; family-combination and contribution-lifecycle tests disappear with the behavior they protected.
+
+The model no longer receives a prose list of sandboxed capability families. It receives exact tool schemas plus one standing file-policy statement. If a future product needs a separate capability inventory, it must be derived from the authoritative per-request assembly rather than reconstructed through backend registration side channels.

+# Agent Note: 不依赖具体能力的沙箱策略上下文
+
+Status: implemented
+
+[English](2026-07-31-capability-neutral-sandbox-policy-context.md) | 中文
+
+## 问题
+
+当前策略上下文最初通过受强制执行家族与可升权家族两个独立注册表来映射运行时组合。后端、工具与示例中的六个调用点会贡献 `filesystem`、`bash` 或 `terminal`；策略服务保留 token 集合，以便独立释放各项注册，对两个注册表的内容求交集并排序，在每次生命周期变化时使提示词组装失效，并且需要测试覆盖所有家族组合。
+
+这份清单既不是说明文件策略所必需的，也不能作为模型可见能力的权威依据。后端贡献可能声明某个家族，而该家族面向模型的工具并不存在，或被请求作用域隐藏；工具 schema 已经向模型准确说明哪些操作可用。因此，为了维护一句近似的英文说明，注册表扩大了公开服务与生命周期契约。
+
+## 决策
+
+`dsh-sandbox-policy` 为每个 agent（智能体）会话贡献一项不依赖具体能力的 `sandbox:policy` 上下文。上下文文本只根据 `resolve({ session })` 派生；不存在后端或工具家族注册 API、贡献映射、排序规则，也不会因注册变化而使提示词失效。

+该文本将能力声明限定于 DSH 文件沙箱所强制执行的可用操作。在 `read-only` 下，它说明这类操作在常驻模式下无法修改文件，并指示模型正常尝试可用工具，随后遵循该工具返回的任何拒绝与升权引导。在 `workspace-write` 下，它说明规范化的会话工作区，以及带有适用条件的临时区域写入许可。在 `danger-full-access` 下，它说明 DSH 文件沙箱不会限制可用操作修改文件。
+
+哪些操作可用仍以工具 schema 为准。针对具体操作的拒绝以及获批后的更宽松模式重试，仍以工具结果为准。文件系统、一次性 bash 与终端实现继续解析并强制执行相同的逐调用策略；移除的只有面向模型的冗余能力清单。
+
+本决策取代了[当前沙箱策略上下文决策](../feature/2026-07-30-current-sandbox-policy-context.md)中关于家族注册与按组合条件化措辞的部分内容。缓存安全的上下文交付、持久快照具体化、措辞证据，以及引导与强制执行之间的边界，仍以该 Agent Note 为归属文档。
+
+## 曾考虑的替代方案
+
+**保留注册表，但减少对应测试。** 不予采用，因为公开方法、保留的生命周期状态、六个贡献点和近似的能力声明仍会存在。组合测试只是体现了这一设计成本，并非成本的成因。
+
+**从工具注册表派生确切清单。** 不予采用，因为当前策略只需要一句符合事实的条件性声明，而确切的可用情况已经体现在组装后的工具 schema 中，并且可能随请求作用域变化。若再把每个 schema 映射回其强制执行后端，就会引入另一项派生关系，而当前没有消费方需要它。
+
+**仅在后端声明会强制执行时提供策略上下文。** 不予采用，因为这会重现注册问题，并使策略是否可见取决于可选贡献方。即使没有可适用的操作，这段带条件的措辞仍然符合事实。
+
+## 后果
+
+策略服务只有一条由归属方直接派生的上下文路径，无需维护两个公开注册表及其释放生命周期。增加或移除能力不再导致运行时上下文快照反复变化，模式和工作区变化仍会触发快照更新。聚焦测试仍覆盖各模式的确切措辞、规范化根目录、模式切换、恢复、服务释放与无 agent 组装；家族组合与贡献生命周期测试则随其所保护的行为一同删除。
+
+模型不再收到以自然语言列出的沙箱能力家族清单，而是收到确切的工具 schema 与一项常驻文件策略声明。未来若产品需要独立的能力清单，该清单必须从权威的逐请求组装结果中派生，不能通过后端注册这种旁路机制重建。

 The shipped TUI and Web compositions register the native DeepSeek adapter plus pi-ai OpenAI and Anthropic profiles. Credentials and endpoint overrides come from the provider-standard `DEEPSEEK_API_KEY` / `DEEPSEEK_BASE_URL`, `OPENAI_API_KEY` / `OPENAI_BASE_URL`, and `ANTHROPIC_API_KEY` / `ANTHROPIC_BASE_URL` pairs in the boot's layered environment.
 
+The Web/headless composition also registers only `web_search`. Search uses DeepSeek's Anthropic-compatible Messages endpoint, resolves the same `DEEPSEEK_API_KEY` reference for every call, and accepts the separate `DEEPSEEK_SEARCH_BASE_URL` endpoint override; each search is an auxiliary model request with its own latency and token cost. `web_fetch` remains disabled and the composition mounts no default fetch provider, so deployments that need arbitrary page retrieval must opt in through an overlay. The TUI composition does not mount Web tools by default. The deployment decision and its security boundary live in the [default Web search Agent Note](../../.agents/notes/implemented/feature/2026-07-31-web-default-search.md).
+
 `DSH_TOOLS_MODE` selects the tool presentation mode for the whole Web/headless process: `native` (the schema default when unset), `code` (the `run_code`-only Code Mode wire), or `both`; any other value fails loud at boot through the `dsh-tools` config schema. It is a TEMPORARY seam — process-wide because Loader composition is static — and is removed once the web UI owns per-session tool-mode selection; the TUI surface ignores it (its config tree pins its own mode).
 
 Every `dsh` surface — TUI, Web, and headless — reports session telemetry by default (the row lives in the shared `base.cordis.yml`): every session-log event streams as OTLP/HTTP log records to `https://harness-telemetry.deepseeksvc.com/v1/logs` on a 10-second batch cadence. `DSH_TELEMETRY_OTLP_URL` points the exporter at a different collector; setting `DSH_TELEMETRY_DISABLED` to ANY non-empty value — including `0` or `false` — disables the row before it loads (a privacy switch prefers off-by-mistake over on-by-mistake). No redaction rule is mounted in this composition yet: exported records are the raw captured copy, including message text, tool arguments and results, and the session's working-directory path. The deployment rulings live in the [web-telemetry-default-mount Agent Note](../../.agents/notes/implemented/feature/2026-07-31-web-telemetry-default-mount.md).

 已交付的 TUI 和 Web 组合会注册原生 DeepSeek 适配器，以及 pi-ai 的 OpenAI 和 Anthropic 提供方配置。凭据和端点覆盖来自启动分层环境中的提供方标准变量对：`DEEPSEEK_API_KEY` / `DEEPSEEK_BASE_URL`、`OPENAI_API_KEY` / `OPENAI_BASE_URL` 和 `ANTHROPIC_API_KEY` / `ANTHROPIC_BASE_URL`。
 
+Web／无头组合还只会注册 `web_search`。搜索使用 DeepSeek 的 Anthropic 兼容 Messages 端点，每次调用都会解析同一个 `DEEPSEEK_API_KEY` 凭据引用，并接受独立的 `DEEPSEEK_SEARCH_BASE_URL` 端点覆盖；每次搜索都是一次辅助模型请求，会产生独立的延迟与 token 成本。`web_fetch` 仍处于禁用状态，组合也未挂载默认抓取提供方；需要任意页面抓取能力的部署必须通过覆盖层选择启用。TUI 组合默认不挂载 Web 工具。部署决策及其安全边界见[默认 Web 搜索 Agent Note](../../.agents/notes/implemented/feature/2026-07-31-web-default-search.md)。
+
 `DSH_TOOLS_MODE` 为整个 Web／无头进程选择工具呈现模式：可选值为 `native`（未设置时的 schema 默认值）、`code`（仅含 `run_code` 的 Code Mode 协议接口）或 `both`；任何其他值都会经由 `dsh-tools` 配置 schema 在启动时明确报错。它是一个临时 seam：Loader 组合是静态的，因此该设置作用于整个进程；待 Web UI 负责逐会话工具模式选择后便会移除。TUI 界面会忽略该变量（其配置树固定了自身模式）。
 
 每个 `dsh` 界面——TUI、Web 与无头——都默认上报会话遥测（该行位于共享的 `base.cordis.yml`）：每条会话日志事件以 OTLP/HTTP 日志记录的形式、按 10 秒批处理节奏流向 `https://harness-telemetry.deepseeksvc.com/v1/logs`。`DSH_TELEMETRY_OTLP_URL` 可将 exporter 指向其他 collector；将 `DSH_TELEMETRY_DISABLED` 设为**任意非空值**——包括 `0` 或 `false`——都会在该行加载前将其关停（隐私开关取「宁可误关、不可误开」）。该组合当前未挂载任何脱敏规则：导出记录即原始捕获副本，包含消息正文、工具参数与结果、以及会话工作目录路径。部署口径见 [web-telemetry-default-mount Agent Note](../../.agents/notes/implemented/feature/2026-07-31-web-telemetry-default-mount.md)。

 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.

 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
 
 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

 Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.

 Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
 
 Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.

-You are an AI agent powered by the DeepSeek Harness SDK.
-
-You are a coding assistant powered by the deepseek-v4-flash model. Your working directory is {{cwd}}. Your bash tool runs under a file sandbox — a `[sandbox: file access denied …]` result is policy, not a command bug.
-
-Verify your work by running the code or tests. Keep answers brief and factual.
-
-
-Use the read tool — not shell commands like cat — to inspect text files. Results include line numbers. Use offset and limit to continue reading large files.
-
-Use the write tool to create files or completely replace file contents. Existing files are overwritten, so read an existing file first (the default fs-policy requires it) and prefer edit for targeted changes.
-
-Use the edit tool for targeted changes to existing UTF-8 text files. It replaces literal old_string with new_string; by default old_string must appear exactly once. If old_string appears multiple times, provide a more specific old_string or set replace_all to true. Read the file first (the default fs-policy requires it), unless you just created or edited it in this session.
-
-Check the [exit code: N] marker on every bash result; investigate failures before moving on.
-
-Track every background task id you start. You are notified in-session when a task finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running task's work. Before giving a final answer, collect every still-relevant task with task_output (set wait: true only when you are genuinely blocked on it), and task_kill tasks that stopped mattering.
-
-Use goal tools for one long-running completion objective in the current session. create_goal may infer goal intent from a direct human request in any language; do not create a goal for routine single-turn work. Call get_goal before update_goal and copy its exact goal_id and revision. After session resume or fork, an active goal is disarmed: when a human asks to continue or resume in any wording or language, use update_goal action resume to rearm it. Mark complete only when the objective is actually achieved. Mark blocked only after the same blocking condition persists for at least 3 consecutive goal rounds, and report that concrete condition in blocked_reason; difficulty, uncertainty, or useful remaining work is not blocked.
-
-<!-- dsh-user-approval-policy:ask -->
-
-Use the workflow tool ONLY when the user explicitly asks for a workflow or for large multi-agent orchestration: you write a JavaScript script (the tool description documents the exact format) that fans work out across many subagents with phases and structured results. For one or two delegations, prefer plain subagent calls.
-
-Use the ralph tool ONLY when the direct human explicitly asks for a Ralph loop or fresh-agent iterative execution. Each Ralph round starts a fresh child with no conversation seed and uses the shared workspace as durable memory. Completion and blockers are worker reports, not independent evaluation. Use same-session goal tools for ordinary long-running objectives, and plain subagents or workflows for bounded delegation and fan-out.
