The ACP provider implements that rule from its closed stop reasons, current operation, closed tool kind, configured permission policy, selected permission outcome, and the managed subprocess exit code or signal.

Tool titles, raw input, locations, option names, and metadata are excluded. A diagnostic-bearing remote `aborted` result keeps its public stop reason; the one-shot Job adapter treats it as failed, while diagnostic-free local cancellation remains killed. + +### ACP facts + +| Stage | Owned operation | Safe categories and facts | +| --- | --- | --- | +| `initialize` | Parent workspace resolution, spawn, and ACP initialize | `configuration`, `transport`, `process-start`, or `process-exit` | +| `new-session` | ACP `session/new` and returned session-id validation | `protocol`, `transport`, or `process-exit` | +| `prompt` | ACP prompt request, remote stop reason, and permission callback | `remote-limit`, `remote-refusal`, `permission`, `transport`, or `unknown` | +| `process` | Managed child exits before a prompt terminal response | `process-exit` plus independently observed exit code and signal | +| `teardown` | EOF quiescence and managed process-tree termination | Fixed teardown facts; the original cleanup failure remains internal | + +`max_turn_requests` remains the shared `error` stop reason and adds `remote-limit`.

Fixed allowlisted facts preserve the actionable distinction without expanding the model-visible trust boundary. + +**Add a shared structured error enum.** ACP and other process-backed providers own different lifecycle points and closed termination vocabularies. A shared enum would invent false equivalence and force unrelated consumers to track provider releases. + +**Parse exception messages or stderr into categories.** Free-form text is neither stable nor safe. Only closed protocol values, typed errors, current call sites, and managed process outcomes qualify as diagnostic inputs. + +**Change existing stop reasons.** The stop reason remains the provider-neutral terminal result. The optional diagnostic explains why a non-completed result needs a different next action without adding new public result states. + +**Add retries, recovery state, or interactive approval.** Diagnostics report a failure; they do not own remediation. Retry policy, session recovery, and human interaction require separate user contracts and lifecycle owners. + +## Consequences + +The parent can distinguish an ACP remote limit, permission involvement, protocol or transport failure, deployment/process failure, and teardown failure without receiving child-controlled text. Startup and cleanup errors use the same safe facts as published results, while Host observation retains the original cause. + +The diagnostic remains display text rather than a public protocol. Consumers may present it but must not branch on its format. This decision adds no retry policy, recovery controller, shared provider-error enum, stderr classifier, authentication taxonomy, session persistence, progress stream, or new ACP capability. diff --git a/.agents/notes/implemented/feature/2026-08-21-out-of-process-subagent-minimal-diagnostics.zh.md b/.agents/notes/implemented/feature/2026-08-21-out-of-process-subagent-minimal-diagnostics.zh.md new file mode 100644 index 0000000000..386f85e6b5 --- /dev/null +++ b/.agents/notes/implemented/feature/2026-08-21-out-of-process-subagent-minimal-diagnostics.zh.md @@ -0,0 +1,73 @@ +# Agent Note: 进程外 subagent 公开最小可行动诊断 + +Status: implemented + +[English](2026-08-21-out-of-process-subagent-minimal-diagnostics.md) | 中文 + +## Problem + +ACP 子进程可能因为达到远端限制、拒绝必需权限、失去协议传输或进程退出而停止。共享结果以往只把这些结果压成 `error` 等结束原因，而启动和清理拒绝的消息还可能暴露原始异常。父 agent 若不读取 Host 日志，就无法决定应缩小任务、调整权限策略还是修复子运行时部署。 + +若把异常、stderr、任务内容、工具输入、路径、环境值、凭证或协议 payload 复制进 `SubagentResult.diagnostic`，不受信任的子进程文本就会变成模型可见内容。若复用完整的产品专属错误联合，又会在提供方无关的 [subagent seam](2026-06-21-subagent-capability-seam.zh.md) 中复制彼此独立版本化的权威。 + +## Decision + +每个进程外提供方分别拥有一份小型映射，把其协议与进程生命周期位置已经收到的事实转换成固定安全展示文本。ACP 提供方使用闭集结束原因、当前操作、闭集工具种类、已配置权限策略、选中的权限结果，以及受管子进程退出码或信号来实现该规则。消费方继续使用现有可选 `SubagentResult.diagnostic`，且不解析其标点或提供方私有 category 名称。 + +### 安全失败文本 + +首行采用以下固定字段顺序： + +```text +Subagent failure (provider: ;

An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

The closed `WebFetchBody` union makes the consumer side fail to compile until the new arm is handled. - Provider-backed extraction as a separate `web_extract` capability, rather than widening `web_fetch` silently. -- Permission policy integration: the permission system now exists ([sandbox and approval](../feature/2026-07-06-sandbox.md), [web permission presets](../feature/2026-07-23-web-permission-and-approval.md)) but bundles only sandbox mode and approval policy; web permission policy remains unintegrated. - Provider-neutral search controls beyond `query` and `maxResults`, once Exa and Perplexity can both honor them honestly. ## Open questions - Should product app packages probe web configuration at startup (treating `WEB_PROVIDER_CONFIGURED_MISSING`, `WEB_PROVIDER_CONFIGURED_UNAVAILABLE`, and `WEB_PROVIDER_AMBIGUOUS` as fatal when web is explicitly configured), or leave misconfiguration to surface at the first execution?

The shipped base has no telemetry redaction rule, so explicitly enabled exports can contain message text, tool arguments and results, and workspace paths; the [default-off Agent Note](../../../.agents/notes/implemented/feature/2026-08-10-telemetry-default-off.md) owns that deployment decision. diff --git a/apps/cli/reference/README.zh.md b/apps/cli/reference/README.zh.md index bf4dc4ca9f..758e7d4835 100644 --- a/apps/cli/reference/README.zh.md +++ b/apps/cli/reference/README.zh.md @@ -88,7 +88,7 @@ dsh web --help ## 共享部署行为 -基础组合包挂载原生 DeepSeek 适配器、settings 与凭据提供方、稳定的 `web_search` 和已禁用的会话遥测。提供方凭据依次从继承环境、`$DSH_HOME/.credentials.yaml`、调用目录的 `.env` 和 `$DSH_HOME/.env` 解析；受管文档从不物化进 `process.env`，而两个 `.env` 文件都是普通启动环境层。搜索使用 `DEEPSEEK_API_KEY` 并接受 `DEEPSEEK_SEARCH_BASE_URL`；只有 patch 层插入提供方并启用 `web_fetch` 后，该工具才可用。 +基础组合包挂载原生 DeepSeek 适配器、settings 与凭据提供方、稳定的 `web_search`、仅限公网的 HTTP fetch 提供方及其单次审批策略，以及已禁用的会话遥测。提供方凭据依次从继承环境、`$DSH_HOME/.credentials.yaml`、调用目录的 `.env` 和 `$DSH_HOME/.env` 解析；受管文档从不物化进 `process.env`，而两个 `.env` 文件都是普通启动环境层。搜索使用 `DEEPSEEK_API_KEY` 并接受 `DEEPSEEK_SEARCH_BASE_URL`。Web app 的 `cordis`、`code` 与 `standard` agent preset 会暴露 `web_fetch`；受限 sandbox mode 对每个公网 URL 调用询问一次，`danger-full-access` 不询问并继续执行，而审批策略 `never` 会在受限模式下直接拒绝且不显示提示。 会话遥测默认留在本地。`DSH_TELEMETRY_MODE=FULL` 将每条已投影会话事件作为 OTLP/HTTP 日志流式发送，`DSH_TELEMETRY_MODE=FEEDBACK_ONLY` 则仅在记录反馈时上传会话日志后缀。`DSH_TELEMETRY_OTLP_URL` 选择其他 collector。任何非空的 `DSH_TELEMETRY_DISABLED` 都是具有最终效力的遥测强制关闭开关。随附基础配置没有遥测脱敏规则，因此显式启用的导出可能包含消息文本、工具参数和结果，以及 workspace 路径；相关部署决策见[默认关闭 Agent Note](../../../.agents/notes/implemented/feature/2026-08-10-telemetry-default-off.zh.md)。 From 470af0a4042d93f2890dbbdb5bd62c65b27b59de Mon Sep 17 00:00:00 2001 From: Dudu-0223 Date: Mon, 24 Aug 2026 14:18:15 +0800 Subject: [PATCH 19/76] fix(web): preserve preview fetch composition --- apps/cli/tests/web-agent-presets.e2e.ts | 2 +- apps/web/tests/preview-boot.e2e.ts | 2 +- apps/web/tests/shipped-composition.e2e.ts | 8 +++++--- apps/web/tests/smoke-real.e2e.ts | 1 + .../webworker-runtime/README.i18n.yaml | 4 ++-- .../experimental/webworker-runtime/README.md | 2 +- .../webworker-runtime/README.zh.md | 2 +- .../webworker-runtime/src/module-proxies.ts | 2 ++ .../node/builtin_modules/mock/dns/promises.ts | 20 +++++++++++++++++++ .../webworker-runtime/src/node/builtins.ts | 2 ++ .../tests/node/node-stubs.spec.ts | 4 +++- .../agent-presets/tests/shipped-root.spec.ts | 12 +++++++---- packages/web/web-fetch-http/src/network.ts | 5 ++++- 13 files changed, 51 insertions(+), 15 deletions(-) create mode 100644 packages/experimental/webworker-runtime/src/node/builtin_modules/mock/dns/promises.ts diff --git a/apps/cli/tests/web-agent-presets.e2e.ts b/apps/cli/tests/web-agent-presets.e2e.ts index 1dc66b2f08..9ef4a489ce 100644 --- a/apps/cli/tests/web-agent-presets.e2e.ts +++ b/apps/cli/tests/web-agent-presets.e2e.ts @@ -231,7 +231,7 @@ describe('the shipped Web composition', () => { expect(toolNames(ctx, handle.agent).filter(name => name !== 'glob' && name !== 'grep')).toEqual([ 'ask_user_question', 'bash', 'create_goal', 'edit', 'exit_plan_mode', 'get_goal', 'interrupt_agent', 'job_kill', 'job_list', 'job_output', 'list_agents', 'ralph', 'read', 'read_image', 'send_message', 'skill', - 'subagent', 'subagent_fork', 'todo_write', 'update_goal', 'web_search', + 'subagent', 'subagent_fork', 'todo_write', 'update_goal', 'web_fetch', 'web_search', 'workflow', 'write', ]) expect(ctx.commands.find(handle.agent, 'goal')).toBeDefined() diff --git a/apps/web/tests/preview-boot.e2e.ts b/apps/web/tests/preview-boot.e2e.ts index 8ef63e1067..002c6c81b9 100644 --- a/apps/web/tests/preview-boot.e2e.ts +++ b/apps/web/tests/preview-boot.e2e.ts @@ -305,7 +305,7 @@ async function bootPreview(origin: string, browser: Browser): Promise { // The hero's workspace picker is the client tree's first interactive // surface, so it appears only once the startup chain completed over the // tunnel. - await page.getByRole('textbox', { name: 'Choose workspace' }).waitFor({ timeout: HERO_TIMEOUT_MS }) + await page.getByRole('button', { name: 'Choose workspace' }).waitFor({ timeout: HERO_TIMEOUT_MS }) const continueButton = page.getByRole('button', { name: 'Continue' }) await continueButton.waitFor({ timeout: 30_000 }) await continueButton.click() diff --git a/apps/web/tests/shipped-composition.e2e.ts b/apps/web/tests/shipped-composition.e2e.ts index 295e861b95..b7dc7e609a 100644 --- a/apps/web/tests/shipped-composition.e2e.ts +++ b/apps/web/tests/shipped-composition.e2e.ts @@ -29,9 +29,10 @@ const FILE_REFERENCE_PROMPT = fileURLToPath(new URL( * The catalog the shipped Web composition puts in front of the model, minus the * ripgrep-dependent pair below.

Provider usage anchors only completed requests: the first multimodal request, images added after the anchor, and offload-set changes all fed automatic compaction a pressure figure that was wrong by orders of magnitude, triggering it far too late (context overflow) or, after a route change, too early. The [version-one simplification](../simplification/2026-07-29-simplify-web-image-input-v1.md) had deliberately rejected a provider-neutral tile formula and deferred visual pricing until a provider-aware estimator had a concrete consumer. + +## Decision + +Compaction pressure is now priced by the routed model's own request projection. `LlmAdapter.imageRequestPricing(provider, model)` is an optional synchronous hook returning an `LlmImageRequestPricing` for one exact route, resolved through `ctx.llm.imageRequestPricing()`; the base adapter declares none and unknown providers degrade to `undefined`, never throw. Each ordered image occurrence resolves to an `LlmImageRequestPrice`: the provider's visual tokens for a retained image plus the model-visible text the wire actually carries (request-preview handle, offload placeholder, or text-only substitution), with the text left to the caller's own estimator so no provider fixes a text tokenization. + +The DeepSeek adapter implements the hook from its connection snapshot (`request-pricing.ts`): uncatalogued and text-only models price every occurrence as its `textOnlyImageText` substitution; image-capable models reproduce the serializer's first-stage oldest-first offload through the shared `offloadedImagePrefixCount()` and price retained images at their `requestImageDimensions` projection with `deepSeekImageTokens()` — a verbatim port of the provider's published v4 vision calculator (14px patches, 3:1 downsampling, 384-token cap, minimum-pixel scale-up, 8:1 width clamp), priced at the worst-case pad-to-4 alignment. The pure geometry moved from `attachment-local` to `dsh-attachment` so provider and pricing share it. + +The token meter's surface fold stores route-neutral facts per node — the fixed-heuristic price, the image-free price, and the durable image occurrences — and `measure()` prices the surface under the effective envelope's route on every call. The anchor holds its raw materials (surface snapshot, provider-output price, usage) instead of a precomputed baseline, so a matching header reprices both the anchor and the current surface under one route and the signed delta compares like with like; the usage-versus-estimated choice happens per measurement against the route-priced anchor. Public `TokenSurfaceNode` carries both `tokens` (route-priced; read by trigger, retention, and range selection) and `heuristicTokens` (fixed; the shadow-price protocol's unit, so `compaction/summary` and `compaction/prune` stay consistent with the O(1) projection fold's own appends). The `contextPressure` and `contextBreakdown` projections deliberately stay on the fixed heuristic. + +The test-support replay adapter declares a flat per-model `imageRequestTokens` so keyless assembled scenarios exercise the seam; the `image-compaction` ACP snapshot proves six inline images push the second turn's pre-step measurement over an automatic threshold that the text-only heuristic stays under, and that the triggered compaction shadows the image message at its heuristic price. + +## Alternatives considered + +**Price images inside the provider-neutral estimator.** Rejected by the [version-one note](../simplification/2026-07-29-simplify-web-image-input-v1.md) and still wrong: visual pricing varies by provider, model, detail mode, and preprocessing, and a hard-coded figure would look authoritative on routes it does not describe. The hook keeps every constant in the adapter that owns the route. + +**Correct pressure only from provider usage.** Usage cannot price the first multimodal request, an image added after the anchor, or a changed offload set — exactly the cases that made compaction fire too late. Usage stays the anchor for completed requests; the route projection prices the increment. + +**Reproduce the full serialization pipeline, including prepared-version bytes and the base64 fallback budgets.** The second-stage offload depends on encoded request bytes that only exist after asynchronous image preparation. The pricing reproduces the deterministic first stage from durable byte lengths; a fallback request can only offload more and cost less, so the estimate stays conservative without I/O in a synchronous hook. + +**Route-price the shadow-price protocol too.** Logged `shadowedTokenCount` feeds the O(1) projection fold, whose appends are priced by the fixed heuristic; pricing replacements by route would make the persisted running total drift. Keeping the protocol on `heuristicTokens` preserves the fold's by-construction agreement. + +**Fold route pricing into the meter's replay state.** A fold keyed to one route would have to replay on every route change and could not answer a `requestHeader` override for a different model. Storing route-neutral node facts and pricing at `measure()` keeps replay single-pass and measurement O(surface), which the contract already promises. + +## Consequences + +Automatic compaction now triggers on the pressure the routed model's next request will actually carry: image-dense DeepSeek sessions compact before overflow instead of after it, text-only routes charge substitution text instead of phantom visual tokens, and offloaded images cost their placeholder. The worst-case alignment pad overprices an image by at most three tokens, and the unreproduced base64-fallback budgets can only overprice — both errors are conservative, and provider usage remains the authoritative anchor once a request completes. The published v4 calculator constants live in `llm-deepseek` alone; if the provider revises its vision projection, that one module and its pinned vectors are the change site. Measurement cost gains one pricing resolution and one image-occurrence walk per call, still O(surface). + +## Testing + +Formula vectors in `image-tokens.spec.ts` pin the published calculator's outputs, including the aspect-clamp, scale-up floor, one-column solver, odd-grid trim, and second-pass convergence cases, cross-checked against the reference implementation over a dimension grid and 50,000-point fuzz during development. `request-pricing.spec.ts` covers text-only substitution, the low-detail preset, and count- and byte-driven offload boundaries. Token-meter specs cover the first multimodal estimate, post-anchor image deltas over usage, text-only repricing under a header override, pricer-less neutrality, occurrence-count mismatch, and nested tool-result images. Compaction specs prove trigger, retention, and range selection read the route price while the logged shadow price stays heuristic. The keyless `image-compaction` ACP snapshot exercises the assembled application end to end. diff --git a/.agents/notes/implemented/feature/2026-08-24-route-priced-image-request-pressure.zh.md b/.agents/notes/implemented/feature/2026-08-24-route-priced-image-request-pressure.zh.md new file mode 100644 index 0000000000..d9cb2b6047 --- /dev/null +++ b/.agents/notes/implemented/feature/2026-08-24-route-priced-image-request-pressure.zh.md @@ -0,0 +1,39 @@ +# Agent Note: 按路由定价的图片请求压力 + +Status: implemented + +[English](2026-08-24-route-priced-image-request-pressure.md) | 中文 + +## Problem + +token 计量服务把 `ImageBlock` 按其持久引用的 JSON 结构计价，约四十个 token，而一张 DeepSeek 请求图片最多消耗 384 个视觉 token，因此图片密集的会话可能携带数十万个未计入估算的 token。provider usage 只锚定已完成的请求：首次多模态请求、锚点之后新增的图片、offload 集合的变化，都会让自动 compaction 拿到数量级错误的压力值，触发得过晚（上下文溢出）或在路由切换后过早。[版本一简化](../simplification/2026-07-29-simplify-web-image-input-v1.zh.md)曾有意否决 provider-neutral 的 tile 公式，把视觉定价推迟到 provider-aware 估算器出现具体消费方之时。 + +## Decision + +compaction 压力现在按路由模型自身的请求投影定价。`LlmAdapter.imageRequestPricing(provider, model)` 是可选的同步钩子，为一条确切路由返回 `LlmImageRequestPricing`，经 `ctx.llm.imageRequestPricing()` 解析；基类不声明定价，未注册的 provider 降级为 `undefined` 而绝不抛出。每个按序的图片出现处解析为一个 `LlmImageRequestPrice`：保留图片的提供方视觉 token，加上线上实际携带的模型可见文本（请求预览句柄、offload 占位文本或纯文本替换），文本交由调用方自己的估算器计价，避免任何提供方固定一种文本 token 化。 + +DeepSeek 适配器基于连接快照实现该钩子（`request-pricing.ts`）：未编目和纯文本模型把每个出现处按其 `textOnlyImageText` 替换计价；支持图片的模型通过共享的 `offloadedImagePrefixCount()` 复现序列化器第一阶段的最旧优先 offload，并按 `requestImageDimensions` 投影尺寸用 `deepSeekImageTokens()` 为保留图片计价，后者是提供方公布的 v4 视觉计算器的逐句移植（14px patch、3:1 降采样、384 token 上限、最小像素放大、8:1 宽度钳制），按最坏的 pad-to-4 对齐计价。纯几何函数从 `attachment-local` 上移到 `dsh-attachment`，供提供方与定价共享。 + +token 计量服务的表层 fold 为每个节点存储与路由无关的事实：固定启发式价格、去图价格与持久图片出现处；`measure()` 在每次调用时按生效 envelope 的路由为表层定价。锚点保存原始材料（表层快照、提供方输出价格、usage）而非预先计算的基线，因此匹配的标头会把锚点与当前表层放在同一路由下重新定价，带符号 delta 的比较口径一致；usage 与估算的选择在每次计量时针对路由定价锚点做出。公开的 `TokenSurfaceNode` 同时携带 `tokens`（路由定价；触发、保留与选段读取它）和 `heuristicTokens`（固定值；影子价协议的计量单位，使 `compaction/summary` 与 `compaction/prune` 与 O(1) 投影 fold 自身的追加保持一致）。`contextPressure` 与 `contextBreakdown` 投影有意保持固定启发式规则。 + +test-support 的回放适配器按模型声明固定的 `imageRequestTokens`，让 keyless 装配场景走通这条 seam；`image-compaction` ACP 快照证明六张内联图片把第二轮 pre-step 计量推过自动阈值，而纯文本启发式保持在阈值之下，且被触发的 compaction 按启发式价格遮蔽了图片消息。 + +## Alternatives considered + +**在 provider-neutral 估算器里为图片定价。** 已被[版本一 note](../simplification/2026-07-29-simplify-web-image-input-v1.zh.md)否决且依然错误：视觉定价随提供方、模型、细节档位与预处理而不同，写死的数字在它不描述的路由上会显得权威却错误。钩子把每个常量留在拥有该路由的适配器里。 + +**只用 provider usage 校正压力。** usage 无法为首次多模态请求、锚点后新增图片或变化的 offload 集合定价，而这些正是让 compaction 触发过晚的情形。usage 仍是已完成请求的锚点；增量由路由投影定价。 + +**复现完整序列化管线，包括请求版本字节与 base64 回退预算。** 第二阶段 offload 依赖异步图片准备之后才存在的编码字节。定价复现由持久字节长度决定的确定性第一阶段；回退请求只会 offload 更多、花费更少，因此估算在同步无 I/O 的钩子里保持保守。 + +**让影子价协议也按路由定价。** 记录的 `shadowedTokenCount` 供 O(1) 投影 fold 消费，而该 fold 的追加按固定启发式计价；替换若按路由定价会让持久化的累计值漂移。协议保持在 `heuristicTokens` 上，维持 fold 的构造性一致。 + +**把路由定价并入计量服务的回放状态。** 绑定单一路由的 fold 在路由每次变化时都得重放，也无法回答指向另一模型的 `requestHeader` 覆盖。存储与路由无关的节点事实并在 `measure()` 时定价，保持单遍回放与契约已承诺的 O(surface) 计量。 + +## Consequences + +自动 compaction 现在按路由模型下一次请求实际携带的压力触发：图片密集的 DeepSeek 会话在溢出之前而非之后压缩，纯文本路由收取替换文本而非幻影视觉 token，被 offload 的图片按占位文本计费。最坏对齐 pad 对单图最多多计三个 token，未复现的 base64 回退预算只会多计——两种误差都偏保守，请求完成后 provider usage 仍是权威锚点。公布的 v4 计算器常量只存在于 `llm-deepseek`；提供方若修订其视觉投影，改动点就是这一个模块与其钉死的向量。每次计量多一次定价解析与一次图片出现处遍历，仍为 O(surface)。 + +## Testing + +`image-tokens.spec.ts` 的公式向量钉死公布计算器的输出，覆盖宽高比钳制、放大下限、单列求解、奇数网格裁剪与第二遍收敛的用例，开发期间与参考实现在尺寸网格及五万点模糊测试上对拍。`request-pricing.spec.ts` 覆盖纯文本替换、低细节预设以及数量与字节驱动的 offload 边界。token-meter 测试覆盖首次多模态估算、usage 之上的锚后图片 delta、标头覆盖下的纯文本重定价、无定价器时的中性行为、出现处数量不匹配与嵌套工具结果图片。compaction 测试证明触发、保留与选段读取路由价格而记录的影子价保持启发式。keyless 的 `image-compaction` ACP 快照端到端验证装配后的应用。 diff --git a/.agents/notes/implemented/simplification/2026-07-29-simplify-web-image-input-v1.i18n.yaml b/.agents/notes/implemented/simplification/2026-07-29-simplify-web-image-input-v1.i18n.yaml index 8c0a5aa1fb..8246ae9618 100644 --- a/.agents/notes/implemented/simplification/2026-07-29-simplify-web-image-input-v1.i18n.yaml +++ b/.agents/notes/implemented/simplification/2026-07-29-simplify-web-image-input-v1.i18n.yaml @@ -2,5 +2,5 @@ # side as of the last confirmed-consistent state.

Adapters whose provider charges visual tokens declare per-route `imageRequestPricing`; `ctx.llm.imageRequestPricing(provider, model)` resolves it synchronously for the token meter. Streaming is a raw chunk protocol (`block-start`, `text-delta`, `reasoning-delta`, `tool-call-delta`, `block-end`, `usage`, `finish`). Every adapter outcome reaches consumers as one terminal `finish`; operational failure uses its `error` or `aborted` reason rather than throwing across the stream API. `BlockAssembler` is the single shared implementation that assembles chunks into blocks/messages. A successful `finish` may carry a `ReplayEnvelope` — opaque response-level replay metadata plus optional per-block entries aligned with the emitted block sequence. Assembly makes one keep/drop decision for content and metadata together: a `max-tokens` finish drops tool calls that may have been truncated, and the envelope loses the entry at each dropped position, so stored metadata always describes stored content. diff --git a/packages/llm/llm/README.zh.md b/packages/llm/llm/README.zh.md index 8af1240cdb..803863d747 100644 --- a/packages/llm/llm/README.zh.md +++ b/packages/llm/llm/README.zh.md @@ -57,7 +57,7 @@ 消息内容是类型化内容块数组：`text`、`reasoning`、`image`、`tool-call`、`tool-result`。`ImageBlock` 只携带持久 `ImageAttachmentRef`；提供方字节和请求尺寸之后再解析。联合仍从可合并扩展的 `ContentBlockMap` 派生，因此插件可以通过 declaration merging 添加其他块类型。assistant 消息使用模型来源，其中携带生成该消息的提供方和模型，以及可选的适配器私有回放状态。dispatch 前，`LlmRuntime` 只在历史提供方路由与目标提供方路由当前由完全相同的适配器实例拥有时才保留该状态；随后由适配器判定能否在模型或提供方间恢复或转换该状态。 -每次分发都使用随适配器世代捕获的确切模型模态。支持图片的适配器把持久图片引用投影为路由专用请求版本。`resolveImageAttachmentAccess()` 单独组合附件提供方可选的宿主对象，以及消费方给出的宿主路径到当前工具执行环境的映射。解析结果不进入 `RequestImageAttachment` 或其 `variantId`。纯文本路由则收到确定性的附件占位文本，其中也包括嵌套工具结果图片，追加式会话历史不会改变。`offloadRequestImagesWithPolicy()` 提供确定性的从旧到新图片移除，支持按原始字节或 base64 计数，也支持图片数量或字节量步长；适配器提供确切派生版本的字节长度和必填的逐图占位文本。 +每次分发都使用随适配器世代捕获的确切模型模态。支持图片的适配器把持久图片引用投影为路由专用请求版本。`resolveImageAttachmentAccess()` 单独组合附件提供方可选的宿主对象，以及消费方给出的宿主路径到当前工具执行环境的映射。解析结果不进入 `RequestImageAttachment` 或其 `variantId`。纯文本路由则收到确定性的附件占位文本，其中也包括嵌套工具结果图片，追加式会话历史不会改变。`offloadRequestImagesWithPolicy()` 提供确定性的从旧到新图片移除，支持按原始字节或 base64 计数，也支持图片数量或字节量步长；适配器提供确切派生版本的字节长度和必填的逐图占位文本，纯函数 `offloadedImagePrefixCount()` 公开同一移除决策，使路由所属的请求定价无需构建投影即可复现它。提供方对图片收取视觉 token 的适配器声明按路由的 `imageRequestPricing`；`ctx.llm.imageRequestPricing(provider, model)` 为 token 计量服务同步解析它。 流式输出是原始分片协议（`block-start`、`text-delta`、`reasoning-delta`、`tool-call-delta`、`block-end`、`usage`、`finish`）。每个适配器结果都以一个终止 `finish` 到达消费方；运行故障使用 `error` 或 `aborted` 作为结束原因，而不会跨流 API 抛出。`BlockAssembler` 是将分片组装为块／消息的唯一共享实现。成功的 `finish` 可以携带 `ReplayEnvelope`——不透明的响应级回放元数据，加上与发射块序列对齐的可选逐块条目。组装对内容与元数据只做一次保留/丢弃决定：`max-tokens` 结束会丢弃可能被截断的工具调用，数据在每个被丢弃的位置同步失去对应条目，因此存储的元数据始终描述存储的内容。 diff --git a/packages/llm/llm/src/content.ts b/packages/llm/llm/src/content.ts index ed97a9b6f1..43c392a641 100644 --- a/packages/llm/llm/src/content.ts +++ b/packages/llm/llm/src/content.ts @@ -81,13 +81,13 @@ export function textOnlyImageText(ref: ImageAttachmentRef): string { * attachment id, so one shared version may serve occurrences whose display * names differ. * @param ref - the occurrence's durable normalized attachment. - * @param version - exact request image shown beside the text. + * @param version - exact request-image dimensions shown beside the text. * @param access - optional path resolved for the current tool execution world. * @returns attachment handle and request-image dimensions. */ export function requestImageHandleText( ref: ImageAttachmentRef, - version: RequestImageAttachment, + version: Pick, access?: ImageAttachmentAccess, ): string { const preview = `Image ${imageIdentity(ref)}; request preview ${version.width}x${version.height}px.` @@ -229,6 +229,39 @@ export function projectImagesForTextModel(messages: readonly Message[]): readonl }) } +/** + * Number of oldest image occurrences one request projection removes, in whole + * count and byte quanta, once a route budget is exceeded.

Process mechanics (spawn, env scrub, tree-scoped teardown) live in the `dsh-subprocess` seam; `subagent-acp` spawns through `ctx.subprocess`, while this backend spawns through the SDK client (the subprocess README's documented exception for SDK-managed transports) and applies the seam's `scrubbedParentEnv()` itself. -`dsh-sdk-jsonrpc-server` keeps serving unchanged (the wire is byte-identical). TypeScript and Python clients both consume the shared protocol through `dsh --profile sdk`; the Python wheel packages that CLI and its closed dependency tree. +`dsh-sdk-jsonrpc-server` validates the exact provider/model/effort route during `initialize`, stores only explicitly supplied effort and token values, and creates every SDK root Agent from that fixed process-wide route. TypeScript and Python clients both expose the same initialization fields through `dsh --profile sdk`; the Python wheel packages that CLI and its closed dependency tree. ## Testing Four tiers, per [testing policy](../../../../docs/testing.md): - **Keyless unit** — `sdk-client` drives a scripted fake runtime (`tests/fake-runtime.ts`, env-scripted, protocol-only — the Python `test_client.py` pattern) over real stdio; `subagent-dsh-sdk` drives the same fake through the real provider. 100% per-file coverage on all three packages. -- **Keyless Loader composition** — `subagent-dsh-sdk/tests/loader-composition.e2e.ts` boots a test-only cordis.yml (`examples/python-sdk-agent/tests/fixtures/subagent/subagent-dsh-sdk/`) where the child is a real second `dsh --profile sdk` runtime with its own isolated home and ordered patch; asserts the parent tool result and the child's own persisted transcript both carry the parent session's cwd. -- **Keyless snapshot** — `examples/python-sdk-agent/tests/sdk.snapshot.ts` drives the real `dsh --profile sdk` runtime through the real `dsh-sdk-client`, replaying recorded fixtures through an ordered `llm-replay` patch. Four scenarios — text turn, bash tool, spawn subagent, and the minimal persistent-tool composition — each pin the normalized notification stream, SDK turn result, and persisted parent and child logs. This also closes the protocol-tier gap the single-exe note's Python-side snapshot left on the vitest side. +- **Keyless Loader composition** — `subagent-dsh-sdk/tests/loader-composition.e2e.ts` boots a test-only cordis.yml (`examples/python-sdk-agent/tests/fixtures/subagent/subagent-dsh-sdk/`) where the child is a real second `dsh --profile sdk` runtime with its own isolated home and ordered patch; it asserts provider/model/reasoning/maxTokens and parent cwd in both the tool result and the child's persisted request header. +- **Keyless snapshot** — `examples/python-sdk-agent/tests/sdk.snapshot.ts` drives the real `dsh --profile sdk` runtime through the real `dsh-sdk-client`. Text, bash, and in-process subagent scenarios replay recorded fixtures through `llm-replay`; the DSH SDK scenario uses deterministic parent and child adapters to pin a model-selected route through the delegation tool, a second SDK runtime, and the child's persisted request header. The minimal persistent-tool scenario covers the smaller shipped profile. Every scenario pins the normalized notification stream, SDK result, and applicable session logs. - **With-key e2e** — the snapshot suite's `DSH_SNAPSHOT=record` mode is the live-API path (it produced the committed fixtures); the composition e2e needs no key by design. ## Alternatives considered diff --git a/.agents/notes/implemented/feature/2026-07-27-typescript-sdk-and-sdk-subagent-backend.zh.md b/.agents/notes/implemented/feature/2026-07-27-typescript-sdk-and-sdk-subagent-backend.zh.md index e97e951028..9288be6f7b 100644 --- a/.agents/notes/implemented/feature/2026-07-27-typescript-sdk-and-sdk-subagent-backend.zh.md +++ b/.agents/notes/implemented/feature/2026-07-27-typescript-sdk-and-sdk-subagent-backend.zh.md @@ -12,20 +12,20 @@ stdio JSON-RPC 对外服务接口（`@deepseek-ai/dsh-sdk-jsonrpc-server`，见[ 三个包，分层与既有 Python 栈完全一致，外加一个 Service Provider 注册： -- **`@deepseek-ai/dsh-sdk-protocol`**（`packages/sdk/protocol/`）—— 把线协议做成共享且具名。`JsonRpcLineTransport` 从 `dsh-sdk-jsonrpc-server` 原样移入（后者现在导入它），`types.ts` 为服务器所说的每个载荷命名：`InitializeParams/Result`、`SessionPromptParams/Result`、四个通知载荷，以及 `HarnessSdkRequestMap`/`HarnessSdkNotificationMap` 索引。该包根显式导出这一完整接口，且不提供指向源模块的深层导入。服务器的 `notify()` 调用点以这些具名载荷标注类型，服务器漂移会先破坏编译而不是破坏客户端。一处行为变化：错误响应现在以携带线上 `code`/`data` 的 `JsonRpcResponseError` 拒绝（Python 客户端本就保留这些；旧传输只抛携带消息的裸 `Error`）。 -- **`@deepseek-ai/dsh-sdk-client`**（`packages/sdk/client/`）—— `python/sdk` 的 TypeScript 孪生：`HarnessClient`（spawn、分帧、通知扇出、有类型的错误表面、经共享 dispose（资源释放）阶梯关闭至完全停稳）之上是 `DeepSeekHarness`/`HarnessSession`（惰性启动、记忆化 `initialize`、`run()` 把一个 `session/prompt` 与其 `session.finished` 配对）。其包根消费方接口显式导出两层客户端、面向调用方的类型，以及协议包所拥有的 `JsonRpcResponseError`；源模块、规范化辅助函数和通知投递端都保留为内部实现。`RunResult.events` 只包含根会话的类型化事件，而 `notifications` 则保留根会话及从 `subagent.started` 发现的后代各自的会话 id；基于 `subagent.started` 血缘边的会话树范围限定在客户端完成，镜像 `client.py`。启动接口解析同版本 `@deepseek-ai/dsh` 依赖并选择具名 profile，可选配置包括 `dshBin`、有序 patch、显式 Harness home、进程 cwd、环境和超时；任意 command/argv 启动只作为内部 fake-runtime 适配器。干净 checkout 中若不存在 `lib/bin.js`，client 会通过绝对 `tsx/esm` loader 使用该包的源码入口，并应用一个省略构建期生成 Typert 贡献加载的内部 patch；SDK 协议不消费这些贡献。`env` 整体替换而非合并，并在 `start()` spawn 时读取，因此凭据策略归调用方，且调用方可在首次使用前完成环境准备。`RunResult` 携带结构化 `reason`（Python 只暴露 `status`）；拆除走私有的 stdin-EOF → SIGTERM → SIGKILL 阶梯直到真正退出（client 运行在任何 harness 上下文之外，无法搭乘 `ctx.subprocess`）。 -- **`@deepseek-ai/dsh-subagent-dsh-sdk`**（`packages/subagent/subagent-dsh-sdk/`）—— 第二个进程外 `SubagentProvider`，采用与 `subagent-acp` 对等的结构：同样的全 false 能力与 `inheritsParentContext: false`，同样的握手后发布所有权事务，同样通过 `onError` sink 将结果归一为绝不拒绝，同样的父命名空间 run id。子答案从流式 `session.event` 读取——最后一条完整 `assistant/message`，否则累积的 `text-delta` 块，部分答案在取消时得以保留。停止原因由子进程的结构化 `TurnEndReason` 映射（`completed`/`max-tokens`/`aborted` 直通；其余一切、包括未运行任何轮次便已结束的子进程，都是 `error`）。其 `dshBin`／profile／patch／home 配置选择隔离的 SDK 应用，`provider`／`model` 写入子进程 `initialize`，`env` 则提供子进程专用的显式值，例如其 API key。 +- **`@deepseek-ai/dsh-sdk-protocol`**（`packages/sdk/protocol/`）—— 把协议格式做成共享且具名。`JsonRpcLineTransport` 位于此处，`types.ts` 为服务器所说的每个载荷命名：`InitializeParams/Result`、`SessionPromptParams/Result`、四个通知载荷，以及 `HarnessSdkRequestMap`/`HarnessSdkNotificationMap` 索引。`InitializeParams` 携带提供方、模型、可选且由适配器持有的推理强度，以及可选输出上限。该包根显式导出完整接口，且不提供指向源模块的深层导入。服务器的 `notify()` 调用点以这些具名载荷标注类型，服务器漂移会先破坏编译而不是破坏客户端。错误响应以携带协议 `code`/`data` 的 `JsonRpcResponseError` 拒绝，与 Python 客户端一致。 +- **`@deepseek-ai/dsh-sdk-client`**（`packages/sdk/client/`）—— `python/sdk` 的 TypeScript 孪生：`HarnessClient`（spawn、分帧、通知扇出、有类型的错误表面、经共享 dispose（资源释放）阶梯关闭至完全停稳）之上是 `DeepSeekHarness`/`HarnessSession`（惰性启动、记忆化 `initialize`、`run()` 持有一次完整活动区间）。其包根消费方接口显式导出两层客户端、面向调用方的类型，以及协议包所拥有的 `JsonRpcResponseError`；源模块、规范化辅助函数和通知投递端都保留为内部实现。`RunResult.events` 只包含根会话的类型化事件，而 `notifications` 则保留根会话及从 `subagent.started` 发现的后代各自的会话 id；基于 `subagent.started` 血缘边的会话树范围限定在客户端完成，镜像 `client.py`。启动接口解析同版本 `@deepseek-ai/dsh` 依赖并选择具名 profile，可选配置包括 `dshBin`、有序 patch、显式 Harness home、进程 cwd、环境和超时；任意 command/argv 启动只作为内部 fake-runtime 适配器。`initialize` 携带提供方、模型、可选推理强度与可选输出上限。干净 checkout 中若不存在 `lib/bin.js`，client 会通过绝对 `tsx/esm` loader 使用该包的源码入口，并应用一个省略构建期生成 Typert 贡献加载的内部 patch；SDK 协议不消费这些贡献。`env` 整体替换而非合并，并在 `start()` spawn 时读取，因此凭据策略归调用方，且调用方可在首次使用前完成环境准备。拆除走私有的 stdin-EOF → SIGTERM → SIGKILL 阶梯直到真正退出，因为 client 运行在任何 harness 上下文之外。 +- **`@deepseek-ai/dsh-subagent-dsh-sdk`**（`packages/subagent/subagent-dsh-sdk/`）—— 第二个进程外 `SubagentProvider`，采用与 `subagent-acp` 对等的结构，但声明 `agentOptions: true`：每次运行都会把提供方／模型／推理强度／maxTokens 合并到实例默认值之上，并且只把这些字段送入子进程 `initialize`。其他启动能力保持 false，`inheritsParentContext: false`。提供方保留握手后发布所有权事务、通过 `onError` sink 将结果归一为绝不拒绝，以及父命名空间 run id。子答案从流式 `session.event` 读取——最后一条完整 `assistant/message`，否则累积的 `text-delta` 块，部分答案在取消时得以保留。停止原因由子进程的结构化 `TurnEndReason` 映射（`completed`/`max-tokens`/`aborted` 直通；其余一切、包括未运行任何轮次便已结束的子进程，都是 `error`）。其 `dshBin`／profile／patch／home 配置选择隔离的 SDK 应用，`env` 则提供子进程专用的显式值，例如其 API key。 -

With no arguments the tool lists registered providers; with `provider` it calls that adapter's advisory model catalog; with `provider` and `model` it resolves the exact model and returns its reasoning efforts and default. At most one instance in a tool scope enables selection because the discovery name is global. Shipped product compositions put `modelSelectionSettings: true` on the primary Agent-scoped `subagent` instance and register the Host-owned `subagent-model-selection` settings namespace with `enabled: false`. A new top-level Session samples that preference during composition and logs an enabled decision as `subagent/model-selection-enabled` before any model request. A child Session inherits the live parent's decision, and a resumed Session uses its existing marker instead of the current preference. Therefore a settings edit affects only subsequently composed top-level Sessions. The fixed discovery definition remains available without the optional LLM service, while discovery and selected-route calls fail until that service is present.

Providers with static route defaults suppress parent-effort inheritance when the request omits effort, preserving the selected model's default. The LLM lookup owns provider registration, exact-model metadata, reasoning-effort validation, and adapter defaults.

Calls with no model-facing selection and no configured route fields preserve the existing provider path without requiring the optional LLM service. An enabled definition registers `list_subagent_models`. With no arguments the tool lists registered providers; with `provider` it calls that adapter's advisory model catalog; with `provider` and `model` it resolves the exact model and returns its reasoning efforts and default. At most one instance in a tool scope enables selection because the discovery name is global. Shipped product compositions put `modelSelectionSettings: true` on the primary Agent-scoped `subagent` instance and register the Host-owned `subagent-model-selection` settings namespace with `enabled: false`. A new top-level Session samples that preference during composition and logs an enabled decision as `subagent/model-selection-enabled` before any model request. A child Session inherits the live parent's decision, and a resumed Session uses its existing marker instead of the current preference. Therefore a settings edit affects only subsequently composed top-level Sessions. The fixed discovery definition remains available without the optional LLM service, while discovery and selected-route calls fail until that service is present.

Taking the parent as a parameter is deliberate — it makes composing a child WITHOUT that join unrepresentable at the call sites, which is the defect the one call exists to prevent. A deployment composing no preset roster joins nothing and needs nothing: its model-facing rows sit in the host composition, where the child already resolves them through the tool registry's global layer. diff --git a/packages/subagent/subagent/README.zh.md b/packages/subagent/subagent/README.zh.md index b1fe2b2742..46cabe00d2 100644 --- a/packages/subagent/subagent/README.zh.md +++ b/packages/subagent/subagent/README.zh.md @@ -42,7 +42,7 @@ subagent seam 允许一个 agent（智能体）通过具名提供方把工作委 - `toolFilter`：应用请求的子 agent 工具限制； - `persona`：应用每个子 agent 独立的 persona。 -两个进程内提供方都会声明 `agentOptions`：创建子 agent 时，请求字段会覆盖父级最新记录请求中的提供方、模型与推理强度；首个请求之前回退到其创建选项，并保留其中配置的 token 上限。更换路由但没有显式指定强度时，会清除继承的路由所属强度，使所选模型解析自己的默认值。DSH SDK 也声明该能力，并实现 `resolveAgentOptions()`，在 Consumer 预检确切路由之前填入其实例持有的 provider／model／maxTokens 默认值；直接调用方进入 `start()` 时会应用同一解析。ACP、Codex 与 Claude Code 声明不支持该能力，因此它们的传输会拒绝配置或模型选择的覆盖，而不会静默忽略。 +两个进程内提供方都会声明 `agentOptions`：创建子 agent 时，请求字段会覆盖父级最新记录请求中的提供方、模型与推理强度；首个请求之前回退到其创建选项，并保留其中配置的 token 上限。更换路由但没有显式指定强度时，会清除继承的路由所属强度，使所选模型解析自己的默认值。DSH SDK 也声明该能力，并公开不可变的 `agentRouteDefaults`，使其实例持有的 provider／model 默认值在确切路由预检前成为 Consumer 的合并基线；`start()` 仍对直接调用方与输出上限负责。ACP、Codex 与 Claude Code 声明不支持该能力，因此它们的传输会拒绝配置或模型选择的覆盖，而不会静默忽略。 每个进程内子 agent 都通过一次 `applyChildComposition(childCtx, parent, composition)` 调用完成组装：先加入父级的 agent-preset 组合，再应用子 agent 自己的 persona 和工具限制。加入父级组合正是子 agent 获得能力的途径：所有面向模型的行都位于 agent 平面，完全没有加入任何组合的子 agent 抵达模型时会看到空的工具注册表（见 [`dsh-agent-presets`](../../preset/agent-presets/README.zh.md)）。将父级作为参数是刻意设计：这让“组装子 agent 却不做该加入”在各调用点无法表达，而这正是这一次调用所要杜绝的缺陷。未组装 preset roster 的部署不加入任何组合、也不需要加入；其面向模型的行位于宿主组合中，子 agent 已能通过工具注册表的全局层解析到它们。 diff --git a/packages/subagent/subagent/src/types.ts b/packages/subagent/subagent/src/types.ts index 23deea7d44..0acdb47438 100644 --- a/packages/subagent/subagent/src/types.ts +++ b/packages/subagent/subagent/src/types.ts @@ -309,15 +309,12 @@ export interface SubagentProvider { */ readonly inheritsParentContext: boolean /** - * OPTIONAL provider-owned resolution for one-shot Agent options.

An explicit or configured provider, model, or effort resolves through `ctx.llm.resolveCallConfig()` after the provider baseline and request precedence are complete. Providers with static route defaults suppress parent-effort inheritance when the request omits effort, preserving the selected model's default. The LLM lookup owns provider registration, exact-model metadata, reasoning-effort validation, and adapter defaults. After the asynchronous lookup, the tool checks cancellation and confirms the same provider instance remains registered before creating a child or background job, so HMR cannot combine one provider's defaults with another provider's process. Calls with no model-facing selection and no configured route fields preserve the existing provider path without requiring the optional LLM service. diff --git a/.agents/notes/implemented/feature/2026-08-18-model-selected-subagent-routes.zh.md b/.agents/notes/implemented/feature/2026-08-18-model-selected-subagent-routes.zh.md index a102609e84..1d83e2e91f 100644 --- a/.agents/notes/implemented/feature/2026-08-18-model-selected-subagent-routes.zh.md +++ b/.agents/notes/implemented/feature/2026-08-18-model-selected-subagent-routes.zh.md @@ -14,7 +14,7 @@ Status: implemented 只有实例启用 `enableModelSelection`，或其 Agent 作用域的 `modelSelectionSettings` 实例解析出已启用的 Session 决定，且绑定的 subagent 提供方声明 `SubagentCapabilities.agentOptions` 时，`dsh-tool-subagent` 才公开可选的 `provider`、`model` 与 `reasoning_effort` 字段，不要求配置路由允许列表。已注册的 LLM 提供方路由都可供子级选择；本工具不会在部署的 LLM 注册表之上增加第二套授权策略。禁用的实例会省略并拒绝面向模型的选择，而配置的 `Config.agentOptions` 仍是部署方所有的默认值。如果提供方缺少该能力，任一种选择模式都会使插件挂载失败。 -提供方与模型共同组成一条路由，必须一起提供。如果配置值、父级值或提供方自有值能够提供生效路由，则可以只提供推理强度。静态的 `provider.agentRouteDefaults` 在存在时构成 provider／model／reasoning 基线；`Config.agentOptions` 与模型参数会在路由相关强度清除之前覆盖它。没有静态默认值的提供方会使用父 Agent 最新记录请求中的兼容字段，首个请求之前由创建选项提供回退，并保留其中配置的输出 token 上限。推理强度 ID 仍由 adapter 所有。只有所选基线的路由不变时才会继承省略的强度；更换提供方或模型但没有指定强度时，会清除下层路由自有的值，使所选模型解析自己的默认值。`AgentOptions` 把结果强度传入子级循环，其请求 header 会记录生效值。可继续描述符会把它与解析后的提供方和模型一同记录，使尚未写入首个请求的子级能以相同选择冷恢复。 +提供方与模型共同组成一条路由，必须一起提供。如果配置值、父级值或提供方持有的路由默认值能够提供生效路由，则可以只提供推理强度。静态的 `provider.agentRouteDefaults` 在存在时构成 provider／model 基线；`Config.agentOptions` 与模型参数会在路由相关强度清除之前覆盖它。没有静态默认值的提供方会使用父 Agent 最新记录请求中的兼容字段，首个请求之前由创建选项提供回退，并保留其中配置的输出 token 上限。推理强度 ID 仍由 adapter 所有。只有所选基线的路由不变时才会继承省略的强度；更换提供方或模型但没有指定强度时，会清除下层路由自有的值，使所选模型解析自己的默认值。`AgentOptions` 把结果强度传入子级循环，其请求 header 会记录生效值。可继续描述符会把它与解析后的提供方和模型一同记录，使尚未写入首个请求的子级能以相同选择冷恢复。 显式或配置的提供方、模型或强度会在提供方基线与请求优先级完成后，通过 `ctx.llm.resolveCallConfig()` 解析。具有静态路由默认值的提供方会在请求省略强度时禁止继承父级强度，从而保留所选模型的默认值。LLM 查询负责提供方注册、精确模型元数据、推理强度校验和 adapter 默认值。异步查询完成后、创建子级或后台 job 之前，工具会再次检查取消状态，并确认同一个提供方实例仍处于注册状态，因此 HMR 不会把一个提供方的默认值与另一个提供方的进程组合。既没有面向模型的选择、也没有配置路由字段的调用会保留原有提供方路径，不要求可选 LLM 服务存在。 diff --git a/docs/subsystems/subagent.i18n.yaml b/docs/subsystems/subagent.i18n.yaml index a0690c5a74..7f8ee525c8 100644 --- a/docs/subsystems/subagent.i18n.yaml +++ b/docs/subsystems/subagent.i18n.yaml @@ -2,5 +2,5 @@ # side as of the last confirmed-consistent state.

When model selection is enabled, its optional fields remain visible without `ctx.llm`; a call that selects a route rejects if the service is unavailable.

Process mechanics (spawn, env scrub, tree-scoped teardown) live in the `dsh-subprocess` seam; `subagent-acp` spawns through `ctx.subprocess`, while this backend spawns through the SDK client (the subprocess README's documented exception for SDK-managed transports) and applies the seam's `scrubbedParentEnv()` itself. -`dsh-sdk-jsonrpc-server` validates the exact provider/model/effort route during `initialize`, stores only explicitly supplied effort and token values, and creates every SDK root Agent from that fixed process-wide route.

Because JSON-RPC requests can dispatch concurrently, it rejects `session/prompt` until one initialization has completed successfully, preventing pending or invalid routes from falling back to constructor defaults.

The first native run exposed two failures hidden by the compatibility lane. Documentation projection tests derived an image basename by splitting only on `/`; they now use Node's platform basename. Chokidar consumers received `%TEMP%` through the `C:\\Users\\RUNNER~1` 8.3 alias while libuv returned the long directory name, tripping its Windows event-path assertion. Shared settings and credentials watchers, plus Cordis module and exact-config HMR, now canonicalize the existing native watch base or deepest existing ancestor before opening the watcher and preserve a missing suffix, while file access and diagnostics retain the configured path. Module HMR attaches listeners and awaits the main watcher's ready event before plugin startup settles, so an immediate post-boot edit cannot race the initial scan. HMR acceptance derives expected identities through the same asynchronous native realpath operation, avoiding a synchronous Windows spelling that can retain the 8.3 alias. diff --git

The permission select rides two new unary RPCs, `session.permissions` and `session.setPermission`, projecting `ctx.permissionPresets` into a protocol-owned `PermissionOption` DTO (the ACP bridge precedent: each protocol owns its presentation shape).

The [Web capability seam decision](../architecture/2026-06-24-web-capability-seam.md) owns the public-fetch security policy and Web preset default. 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.

Composition smokes pin the shared search roster and per-preset fetch choices; the built composition dump pins the one-minute shipped search budget; provider tests pin missing, stored, and rotated credential behavior plus literal and ambient compatibility. diff --git a/.agents/notes/implemented/feature/2026-07-31-web-default-search.zh.md b/.agents/notes/implemented/feature/2026-07-31-web-default-search.zh.md index a782c4b58b..825f0ee3f8 100644 --- a/.agents/notes/implemented/feature/2026-07-31-web-default-search.zh.md +++ b/.agents/notes/implemented/feature/2026-07-31-web-default-search.zh.md @@ -10,13 +10,13 @@ Status: implemented ## 决策 -`apps/cli/config/base.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` 和 `searchTimeoutMs: 60000` 挂载 `dsh-tool-web`。它不挂载 `dsh-web-fetch-http`，也不选择抓取提供方。共享 base 只将 `web_search` 设为 TUI、浏览器与无头会话的默认工具。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。已交付的一分钟预算用于覆盖一次辅助 DeepSeek Messages 请求及服务端检索，同时保持 `dsh-tool-web` 提供方无关的 30 秒默认值不变，以供自定义组合使用。 +`apps/cli/config/base.cordis.yml` 明确挂载 `dsh-web`，配置 `searchProvider: deepseek-official` 与 `fetchProvider: http`，同时挂载 `dsh-web-search-deepseek`、`dsh-web-fetch-http`，并以 `fetch: false` 和 `searchTimeoutMs: 60000` 挂载 `dsh-tool-web`。因此，共享 base 只会暴露 `web_search`，除非产品 preset 启用抓取；已交付的 Web `cordis`、`code` 与 `standard` preset 会启用抓取。显式提供方 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。已交付的一分钟预算用于覆盖一次辅助 DeepSeek Messages 请求及服务端检索，同时保持 `dsh-tool-web` 提供方无关的 30 秒默认值不变，以供自定义组合使用。[Web 能力 seam 决策](../architecture/2026-06-24-web-capability-seam.zh.md)负责公开抓取安全策略与 Web preset 默认值。 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` 的现有约定。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。已交付的 `workspace-write` 默认值只管辖文件修改；若产品采取受限网络策略，就需要添加 `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。 +默认挂载不会创建 Web 专用权限策略。`web_search` 与已启用的 `web_fetch` 调用会在 bash／文件系统沙箱及审批 preset 之外执行，并遵循 `dsh-tool-web` 的现有约定。HTTP 提供方把抓取限制到已验证的公开目的地址，但不限制公开数据出站。已交付的 `workspace-write` 默认值只管辖文件修改；若产品采取受限网络策略，就需要添加 `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 @@ -30,8 +30,8 @@ DeepSeek 搜索使用与官方会话适配器相同的 `DEEPSEEK_API_KEY` 凭据 **提高 `dsh-tool-web` 的提供方无关超时。** 不予采纳：自定义提供方和部署有各自不同的延迟预期；这一部署预算应归已交付的 DeepSeek 组合所有。 -**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-http`，并将 `dsh-tool-web` 的 `fetch` 选项设为 `true`。 +**在每个共享 base surface 上启用抓取。** 不予采纳：共享 base 服务于网络策略不同的产品。它会挂载仅限公网的提供方，但保持工具按需启用；已交付的 Web preset 会有意启用该工具，其他产品则可以继续隐藏它或添加更严格的网络策略。 ## 后果 -每个已交付界面的原生模型请求都只会携带 `web_search` schema，以及仅用于搜索的提示词指引；Web／无头 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。TUI/Web 组合冒烟测试固定了共享的 `web_search` 清单及不提供 `web_fetch` 这一事实；构建后组合配置的转储固定了已交付的一分钟搜索预算；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。 +每个共享 base surface 的原生模型请求都会携带 `web_search` schema 与搜索指引；Web／无头 Code Mode 通过 `run_code` 公开相同的搜索能力。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。已交付的 Web `cordis`、`code` 与 `standard` preset 还会暴露 `web_fetch`，实施公开地址强制校验且无需逐次审批。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。组合冒烟测试会固定共享搜索清单与各 preset 的抓取选择；构建后组合配置的转储固定已交付的一分钟搜索预算；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。 diff --git a/apps/cli/composition.md b/apps/cli/composition.md index d76ed6b568..2ba70f4088 100644 --- a/apps/cli/composition.md +++ b/apps/cli/composition.md @@ -160,8 +160,6 @@ flowchart LR cfg --> plugin_dsh_base_web_search_deepseek plugin_dsh_base_web_fetch_http["web-fetch-http

A conservative 512-level lexical guard and conversion exceptions produce a fixed omission marker rather than raw HTML, and table `colspan` is ignored because GFM has no spanning-cell representation; these bounds avoid blocking the event loop or expanding output from an untrusted numeric attribute ([archived dependency decision](../../../.agents/notes/archived/simplification/2026-07-26-turndown-for-tool-web-html-markdown.md)). - **The model-facing API is minimal by design, with promotions deferred** — `max_results` stays a config bound (not a model argument), and `web_fetch` takes only `url` (no `format`/`prompt`/LLM-summarization mode); both are named later steps in [the seam Agent Note](../../../.agents/notes/implemented/architecture/2026-06-24-web-capability-seam.md). -- **Permission remains composition-owned** — this tool package does not request `ctx.approval` itself. Shipped compositions mount [`dsh-web-fetch-approval-policy`](../web-fetch-approval-policy/README.md) for `web_fetch`; custom compositions may replace it, and no package defines persistent URL/domain grants. +- **Public fetches do not request approval** — the shipped `cordis`, `code`, and `standard` presets expose `web_fetch` in every sandbox and approval mode. The HTTP provider blocks non-public destinations, but a model can send data to a public URL. Deployments that require per-call confirmation must add a `tools/pre-execute` policy or disable fetch. diff --git a/packages/web/tool-web/README.zh.md b/packages/web/tool-web/README.zh.md index c69e0ccb79..65fcc28591 100644 --- a/packages/web/tool-web/README.zh.md +++ b/packages/web/tool-web/README.zh.md @@ -151,4 +151,4 @@ schema 校验会在执行前拒绝缺失或非数组的 `queries` 字段以及 - **没有覆盖整个批次的原生搜索计数器**：`searchMaxQueries` 限制 `ctx.web.search` 调用数，但提供方可以在每次调用内执行多次原生搜索。例如，配置了 `maxUses` 的模型型提供方最多可以执行 `searchMaxQueries × maxUses` 次原生搜索；`searchMaxResults` 只限制返回给调用方的组合来源。部署通过这些独立的消费方与提供方设置控制成本，因为通用 seam 不知道提供方内部的搜索计量单位。 - **HTML→markdown 转换会省略无法安全表示的输入**：[turndown](https://github.com/mixmark-io/turndown)（带 GFM 表格／删除线）通过真实 DOM 转换至多 `fetchMaxOutputChars` 个源字符。保守的 512 层词法守卫和转换异常会产生固定省略标记，而不会返回原始 HTML；表格的 `colspan` 会被忽略，因为 GFM 无法表示跨列单元格。这些限制可避免阻塞事件循环，也避免不受信任的数值属性使输出膨胀（[已归档的依赖决策](../../../.agents/notes/archived/simplification/2026-07-26-turndown-for-tool-web-html-markdown.md)）。 - **面向模型的接口有意保持精简，后续扩展暂缓**：`max_results` 保持为配置上限（不是模型参数），`web_fetch` 只接受 `url`（没有 `format`／`prompt`／LLM（大语言模型）摘要模式）；两项都列为 [seam Agent Note](../../../.agents/notes/implemented/architecture/2026-06-24-web-capability-seam.zh.md) 中的后续步骤。 -- **权限仍由组合负责**：此工具包自身不会请求 `ctx.approval`。已交付的组合为 `web_fetch` 挂载 [`dsh-web-fetch-approval-policy`](../web-fetch-approval-policy/README.zh.md)；自定义组合可以替换它，且没有任何包定义持久化的 URL／域名授权。 +- **公开抓取不会请求审批**：已交付的 `cordis`、`code` 与 `standard` preset 会在所有 sandbox 和审批模式下暴露 `web_fetch`。HTTP 提供方会阻断非公开目的地址，但模型仍可把数据发送到公开 URL。要求逐次确认的部署必须添加 `tools/pre-execute` 策略或禁用抓取。 diff --git a/packages/web/web-fetch-approval-policy/README.i18n.yaml b/packages/web/web-fetch-approval-policy/README.i18n.yaml deleted file mode 100644 index fc40285eaa..0000000000 --- a/packages/web/web-fetch-approval-policy/README.i18n.yaml +++ /dev/null @@ -1,6 +0,0 @@ -# Bilingual-pair consistency record (docs/i18n/README.md): the git blob hash of each -# side as of the last confirmed-consistent state.

The current Session's group opens automatically only when the user has not already stored an explicit state for that Workspace.

After a ready Workspace baseline changes, the browser removes expansion, order, and observed-timestamp records for ids absent from that baseline while retaining the Ungrouped and flat-list accounts. The combined view menu offers **Manual** and **Last updated** in grouped and flat presentation, with one browser-local persisted order per account. A real Workspace initializes from `WorkspaceView.sessionIds`; Ungrouped and the cross-Workspace flat list initialize from recency and have no Host Session account. Entering Last updated performs one complete recency sort; a later user prompt or steer promotes that Session once, and dragging may edit the resulting order. Returning to Manual preserves the current order and only disables later activity promotion. Manual-mode drags for a real Workspace also write the Host Session account, while Ungrouped and flat-list drags and activity promotion remain browser-local. Flat rows omit an empty leading status slot because they have no parent hierarchy, while a visible status retains its slot. -When New Session creation selects a blank Session, the browser promotes it once in both its grouped account and the flat-list account.

A Workspace remembers whether it is closed or showing Sessions; an open Workspace shows five non-blank Sessions by default, keeps the selected blank **New Session** as one provisional extra row until its first prompt, offers a transient **Show more** control for the hidden remainder, and returns to that folded projection after the whole Workspace is closed and reopened. Creating a Session from a Workspace row first opens that group so the new row remains visible when the Session state arrives. Once the Workspace list baseline is ready, browser-persisted expansion and Session-order records retain only current Workspace ids plus Ungrouped and the flat-list account.

Dragging edits the current order in either mode; Manual-mode drags for real Workspaces also update the Host Session account, while Ungrouped and flat-list orders remain browser-local because neither has one Workspace account. A collapsed group resolves drag boundaries from its rendered rows and places the source ahead of intervening hidden rows, so the dragged row cannot disappear into the remainder. Flat rows omit the empty leading status slot because they have no parent hierarchy, but retain it when a Session status is visible. Workspace drag order is Host-durable in either Session order mode. Collapsed search is one header action beside the view and add actions. In the rail, add and search render as 36px controls on the shell's shared horizontal entry path. Activating search expands the field across the header; an outside click collapses only a query that is empty after trimming — except while the rail search gesture is still in flight (until focus lands in the input after the column slide), so the expanding click cannot dismiss the search it opened — while the clear control always resets and collapses it. A non-blank search query replaces either browsing mode with one flat result list: case-insensitive title and Workspace substring matches appear immediately, while a 250 ms debounced Host request adds ranked current-conversation content matches and snippets. The English search input and its defensive request path remove NUL, cap the query at the wire schema's 500 UTF-16 code units without splitting a surrogate pair, and preserve the existing debounce and cancellation behavior. Each new query aborts the preceding request; a failed content search leaves metadata matches visible with a warning. The list is capped at 20, asks the user to narrow broader queries, and opens the selected Session without clearing the query or jumping to a specific event. diff --git a/packages/client/ui-workspace/README.zh.md b/packages/client/ui-workspace/README.zh.md index 93d117996e..e85b7d25e5 100644 --- a/packages/client/ui-workspace/README.zh.md +++ b/packages/client/ui-workspace/README.zh.md @@ -4,7 +4,7 @@ 共享 Workspace 浏览器与选择器插件。`WorkspaceBrowser` 填充侧边栏的 `sidebar.workspaces` slot，`WorkspacePicker` 则填充页面局部 Session Intent 主视觉区的 `conversation.hero.workspace` slot；两个界面使用同一套 Workspace 菜单和添加流程。 -该浏览器通过全局运行时钩子将 Session 行渲染为分组或扁平形式，并负责 Workspace 添加／重命名／重排序以及 Session 重排序。每个 Workspace 会记住自身是关闭还是显示 Session；打开后默认显示五条 Session，其余条目通过临时的**展开其余**控件显示，而关闭并重新打开整个 Workspace 后会恢复为五条。从 Workspace 行创建 Session 时会先打开该分组，使 Session 状态到达后新行保持可见。Workspace 列表基线就绪后，浏览器持久化的展开状态与 Session 顺序记录只保留当前 Workspace id、Ungrouped 和单列表记账。视图选项把分组方式和每个记账各自的一份浏览器持久化 Session 顺序放在一起：真实 Workspace 从 `WorkspaceView.sessionIds` 初始化，Ungrouped 和跨 Workspace 的单列表则从最近更新时间顺序初始化。**手动排序**和**最近更新**在两种呈现方式下都可用。进入最近更新时会执行一次完整的时间排序，后续 user prompt 或 steer 会将对应 Session 置顶一次；进入手动排序则保留所有当前位置并停用后续置顶。两种模式下的拖拽都会编辑当前顺序；真实 Workspace 在手动模式下的拖拽还会更新 Host Session 记账，而 Ungrouped 和单列表因没有单一 Workspace 记账，其顺序始终只保存在浏览器本地。单列表没有父级层次，因此不显示空的左侧状态槽；Session 存在可见状态时仍保留该槽。无论采用哪种 Session 顺序，Workspace 拖拽顺序都由 Host 持久化。 +该浏览器通过全局运行时钩子将 Session 行渲染为分组或扁平形式，并负责 Workspace 添加／重命名／重排序以及 Session 重排序。每个 Workspace 会记住自身是关闭还是显示 Session；打开后默认显示五条非空白 Session，当前选中的空白**新会话**在首条提示词落地前作为一条临时额外行保留，其余隐藏条目通过临时的**展开其余**控件显示，而关闭并重新打开整个 Workspace 后会恢复为该折叠投影。从 Workspace 行创建 Session 时会先打开该分组，使 Session 状态到达后新行保持可见。Workspace 列表基线就绪后，浏览器持久化的展开状态与 Session 顺序记录只保留当前 Workspace id、Ungrouped 和单列表记账。视图选项把分组方式和每个记账各自的一份浏览器持久化 Session 顺序放在一起：真实 Workspace 从 `WorkspaceView.sessionIds` 初始化，Ungrouped 和跨 Workspace 的单列表则从最近更新时间顺序初始化。**手动排序**和**最近更新**在两种呈现方式下都可用。进入最近更新时会执行一次完整的时间排序，后续 user prompt 或 steer 会将对应 Session 置顶一次；进入手动排序则保留所有当前位置并停用后续置顶。两种模式下的拖拽都会编辑当前顺序；真实 Workspace 在手动模式下的拖拽还会更新 Host Session 记账，而 Ungrouped 和单列表因没有单一 Workspace 记账，其顺序始终只保存在浏览器本地。折叠分组按当前渲染行确定拖拽边界，并把来源行放在中间隐藏行之前，因此拖动行不会掉入隐藏的剩余项。单列表没有父级层次，因此不显示空的左侧状态槽；Session 存在可见状态时仍保留该槽。无论采用哪种 Session 顺序，Workspace 拖拽顺序都由 Host 持久化。 折叠搜索是视图和添加操作旁的一枚区头按钮。在轨道中，添加和搜索会渲染为沿外壳共用横向进入路径移动的 36px 控件。激活搜索后，输入框会扩展并占据区头；点击外部只会收起经清除首尾空白后为空的查询——但轨道搜索手势仍在进行期间（直至列滑动结束、焦点落入输入框）除外，这样触发展开的那次点击不会收起它刚打开的搜索——而清除控件总会重置并收起搜索。非空白查询会以单一扁平结果列表替代任一浏览模式：不区分大小写的标题和 Workspace 子串匹配项会立即显示，经 250 ms 防抖的 Host 请求则会加入经过排序的当前对话内容匹配项及其摘要片段。英文搜索输入框及其防御性请求路径会移除 NUL，将查询限制在传输 schema 规定的 500 个 UTF-16 代码单元内且不会拆分代理项对，并保留现有的防抖与取消行为。每次新查询都会中止前一个请求；内容搜索失败时，元数据匹配项仍会显示，同时给出警告。列表最多显示 20 条结果，并会在查询过宽时提示用户缩小范围；打开所选 Session 时既不会清除查询，也不会跳转至特定事件。 diff --git a/packages/client/ui-workspace/src/client/rows/WorkspaceBrowser.tsx b/packages/client/ui-workspace/src/client/rows/WorkspaceBrowser.tsx index c95ad179e9..2b2aba93ce 100644 --- a/packages/client/ui-workspace/src/client/rows/WorkspaceBrowser.tsx +++ b/packages/client/ui-workspace/src/client/rows/WorkspaceBrowser.tsx @@ -40,6 +40,21 @@ const SEARCH_QUERY_MAX_CODE_UNITS = 500 /** Session rows visible per Workspace before the local overflow control. */ const COLLAPSED_SESSION_LIMIT = 5 +/** Fold one Workspace without charging its provisional New Session against the ordinary-row limit. */ +function collapsedSessionRows(sessions: readonly SessionNode[]): { + rows: readonly SessionNode[] + hiddenCount: number +} { + let ordinaryCount = 0 + const rows = sessions.filter((session) => { + if (session.blank) return true + if (ordinaryCount >= COLLAPSED_SESSION_LIMIT) return false + ordinaryCount += 1 + return true + }) + return { rows, hiddenCount: sessions.length - rows.length } +} + /** Keep controlled input and RPC payload inside the session.search wire contract. */ function sanitizeSearchQuery(value: string): string { const withoutNul = value.replaceAll('\0', '') @@ -339,22 +354,47 @@ function SessionTree({ setDrag(null) const group = groups.find(candidate => candidate.key === activeDrag.accountKey) if (group === undefined) return - const targetIndex = group.sessions.findIndex(session => session.id === over.id) + const sessionsExpanded = expandedSessionGroups.includes(group.key) + const renderedSessions = sessionsExpanded ?

Reader links each state to the prior same-kind Context instead of inventing a lifecycle ID for the entire Inbox. +Request Prompt demonstrates shared pure interpretation without shared target State: Chat and Trajectory call `inspectRequestPrompt()` from their own Definitions. The function canonicalizes the full header and classifies model-visible system/tool differences; each target then chooses its own output. Chat materializes every header carrying a non-empty system field, including `series` snapshots that repeat an unchanged header for an explicitly declared series or a post-replacement request, while Trajectory retains the complete request fact and its change classification. Ordinary append-only later Turns do not write another unchanged header. The first header in a Step follows the provider envelope rather than the header Event position: step one uses the owning Turn start and later steps use their Step start, placing the system field before the request's user-role messages; a later header in the same Step stays at its own Event after the surface rewrite that began the new series. When the preceding header is outside a partial window, a non-`initial` header stays at its own Event until prepend supplies that predecessor. Every header is a full snapshot, so a first loaded `resume`, `change`, or `series` header can render its system field without fabricating a comparison to unloaded history. + Retry, Assistant, and Turn Tail demonstrate independent claims on one Event.

Rendering that field as Markdown would restyle it — headings, emphasis, lists — so a reader would see a rendered document the model never received. Context injection already solves the same job with a 141px code-block scrollport and `
` text that keeps the bytes and line breaks the model read, so the row needs that presentation, not a second one.
+
+## Decision
+
+`SystemPromptRow` mounts the same expanded body as an opaque context injection. It reuses `ContextInjectionRow.module.css` for the 141px Figma 10:2482 scrollport and renders the durable `request/header` system string through `OpaqueBody` as one text block, so the disclosure shows model-facing text with its real line breaks and the same 20_000-character display bound. The row stays collapsed by default and still has no streaming path. It does not grow a producer label, form marker, or source-field list: the system field is one joined string on the header, not a sourced `user/message`.
+
+## Alternatives considered
+
+**Render settled Markdown in a card-styled body.** The chrome could match, but Markdown rewrites what the model read. A heading or bold span is a different document from the request bytes.
+
+**Split the joined system string into snapshot sections.** The durable header stores only the assembled text. Inventing section boundaries in the client would attribute prose the log does not name, and a resumed or foreign header could not reconstruct them.
+
+**Render through `ContextInjectionRow` itself.** That row is for sourced user-role messages: it titles a role, shows a producer, and chooses a form body. The system field is a different durable fact and has none of those fields.
+
+## Consequences
+
+The two disclosures now share one expanded-body chrome and one text presentation, so a later change to the 141px scrollport or the opaque bound applies to both. The cost is that a long system prompt scrolls inside 141px instead of 360px, and Markdown markup in the prompt stays visible as characters.
+
+## Testing
+
+`packages/client/ui-chat/tests/system-prompt-row.client.spec.tsx` expands and collapses the row and pins the opaque `[data-context-text]` bytes, including Markdown markers that must not become a heading. `apps/web/tests/replay-round-trip.e2e.ts` still opens the assembled disclosure and reads the persona line from that body.

+# Agent Note: System prompt expands into the opaque context body

+Status: implemented
+
+[English](2026-08-17-web-system-prompt-opaque-body.md) | 中文
+
+## Problem
+
+Chat 的 `系统提示词` 行和上下文注入共用 `DisclosureRow` 外壳，其展开内容区需要呈现请求的 system 字段。如果把该字段渲染成 Markdown——标题、强调、列表——读者看到的将是模型从未收到的排版文档。上下文注入已经用 141px 代码块滚动区和保留模型所见字节与换行的 `
` 文本解决了同一件事，因此该行需要复用这一呈现，而不是再造一套。
+
+## Decision
+
+`SystemPromptRow` 展开后挂载与不透明上下文注入相同的内容区。它复用 `ContextInjectionRow.module.css` 的 Figma 10:2482 的 141px 滚动区，并把持久 `request/header` 的 system 字符串作为一块文本交给 `OpaqueBody`，因此展开后看到的是带真实换行的模型可见文本，以及相同的 20_000 字符显示上限。该行默认折叠，仍然没有流式路径。它不增加生产者标签、form 标记或 source 字段列表：system 字段是 header 上的一段拼接字符串，不是带 source 的 `user/message`。
+
+## Alternatives considered
+
+**在卡片式内容区里渲染结算后的 Markdown。** 外壳可以对齐，但 Markdown 会改写模型读到的内容。标题或加粗是另一份文档，不是请求里的字节。
+
+**把拼接后的 system 字符串拆成 snapshot 分段。** 持久 header 只保存组装后的文本。客户端臆造分段边界会把日志未命名的正文归到某个子系统，恢复或外来 header 也无法重建这些分段。
+
+**直接走 `ContextInjectionRow`。** 那一行面向带 source 的 user-role 消息：它标角色、显示生产者，并按 form 选内容区。system 字段是另一件持久事实，没有这些字段。
+
+## Consequences
+
+两处展开现在共用同一套内容区外壳和同一套文本展示，因此之后改 141px 滚动区或不透明显示上限会同时作用到两边。代价是较长的系统提示词在 141px 而不是 360px 内滚动，提示词里的 Markdown 标记会以字符形式可见。
+
+## Testing
+
+`packages/client/ui-chat/tests/system-prompt-row.client.spec.tsx` 会展开并折叠该行，并钉住不透明 `[data-context-text]` 字节，包括不得变成标题的 Markdown 标记。`apps/web/tests/replay-round-trip.e2e.ts` 仍会打开组装后的展开行，并从该内容区读出 persona 行。

+Request headers use canonical full snapshots only. Initial and resume anchors remain full snapshots even when unchanged; an in-instance change appends another full `request/header` with reason `change`; and an unchanged envelope beginning an explicitly declared message series or following a surface replacement appends a full snapshot with reason `series`. Ordinary append-only later Turns, further Steps, and retries in that model-message series inherit the latest snapshot. The delta event, codec types, diff/apply helpers, and codec-only `fallback` reason are removed. Request reconstruction selects the latest snapshot.
 
 `SESSION_FORMAT_VERSION` remains pinned at `0`, so seed, append, and persistence-load validation explicitly reject old v0 `request/header-delta` events and full snapshots carrying the removed `fallback` reason. There is no compatibility fold or migration. JSONL and SQLite tests pin this fail-loud boundary, and the ACP snapshot harness represents legitimate mid-session changes as full pinned headers and full readable prompts.

Listeners may rewrite the claimed messages or reject them outright; a rejected or empty first claim still closes a durable turn that spent no step, so the log records the attempt. An enter decision may also set `startsRequestSeries` to begin a distinct model-message series: the loop then logs a fresh `request/header` (reason `series`, or `change` carrying `startsSeries: true` when the envelope changed too). A listener that rebuilds a downstream enter decision must spread it (`{ ...decision, messages }`) so the declaration survives. Each step reads the prompt sections and tool schemas that plugins registered.

 The browser Chat target for Conversation assembly. It registers Chat event definitions and snapshot construction, supplies `useChat`, renders transcript nodes and details, and owns Chat-specific stores, actions, localization, and scroll restoration; historical image URLs resolve through the Conversation-owned per-session cache (`ctx.uiConversation.imageUrl`).
 
+## System prompt row
+
+Chat contributes a `System prompt` row for a non-empty initial or resumed request, an explicit series start, or an actual system-field change; same-series config-only or tool-only changes, tool steps, and retries do not duplicate it. Chat places the first header in a step at that request's message boundary — turn start for step one, step start thereafter — before the user-role messages sent with the request, matching the provider envelope's system-before-messages order; when the preceding header is outside a partial window, a non-initial header stays at its own Event and renders conservatively until prepend supplies that predecessor. The row stays collapsed by default and mounts the complete prompt in the same 141px code-block body as an opaque context injection — model-facing text with its real line breaks, not Markdown — only while expanded; it has no streaming path. Systemless headers produce no row.
+
 ## Model Experience
 
 None, as this package renders logged conversation state in the browser and registers nothing model-facing.

+## 系统提示词行
+
+Chat 会为非空的初始或恢复请求、显式序列起点，或 system 字段真实变化贡献一行 `系统提示词`；同一序列内仅配置变化或仅工具变化、工具 step 和重试不会重复该行。Chat 会把一个 step 中的首条 header 放在该请求的消息边界——step one 使用 turn start，其余 step 使用 step start——位于该请求发送的 user-role 消息之前，与提供方信封「system 在 messages 之前」的顺序一致；部分窗口未包含前序 header 时，非 initial header 会保留在自身 Event 并保守渲染，直到 prepend 补入前序 header。该行默认折叠，仅在展开期间把完整提示词挂到与不透明上下文注入相同的 141px 代码块内容区——保留模型所见真实换行的模型可见文本，而非 Markdown；它没有流式路径。无系统提示词的 header 不生成行。

 无，因为本包在浏览器中渲染已记录的对话状态，不注册任何面向模型的内容。

 Every provider call that reaches a successful finish appends exactly one `assistant/message` completion anchor, including content-less calls and `max-tokens` finishes. The anchor records the assembled content as-is, lists the exact chunk seqs in `sourceEventSeqs` (`[]` for a stream with no chunks), and includes usage when available; empty content stays out of derived message history. A turn cancellation that interrupts streaming also appends an `interrupted: true` anchor when non-empty text or reasoning has reached the user. The anchor cites those chunk seqs and places the rendered prefix in derived message history, so the next request contains what the user saw. Undispatched tool calls are omitted, and an empty or tool-only stream produces no anchor; provider failures still commit no assistant content ([decision](../../../.agents/notes/implemented/architecture/2026-08-10-cancelled-stream-prefix-finalize.md)).
 
-After `agent/request` returns a provider/model call config, the loop asks `ctx.llm.prepareCall()` to validate adapter-owned fields and materialize configured reasoning-effort and output-token defaults under the active turn signal. The prepared call retains the exact adapter registration across this asynchronous resolution, `request/header` logging, and terminal dispatch, so HMR cannot mix one adapter's capability result with another adapter's request. The header records the effective config and which fields came from the adapter. Before the next waterfall, the loop removes those marked fields from the proposal so the current exact route rematerializes its own defaults; unmarked explicit settings persist across steps and route changes. A route with no registered adapter preserves the proposed config so an `llm/stream` listener can own and short-circuit it; unhandled terminal dispatch still fails with `NO_ADAPTER`. A new loop instance follows the same adapter-default marker rule when resuming.

The prepared call retains the exact adapter registration across this asynchronous resolution, `request/header` logging, and terminal dispatch, so HMR cannot mix one adapter's capability result with another adapter's request. The header records the effective config and which fields came from the adapter. The loop appends a full snapshot for its first request, for a changed header, and when an unchanged header begins an explicitly declared message series or the first request after a surface replacement. A changed header that also begins a series carries `startsSeries: true`; further same-series Steps, ordinary later Turns, and retries with an unchanged header inherit the latest snapshot. Before the next waterfall, the loop removes adapter-marked fields from the proposal so the current exact route rematerializes its own defaults; unmarked explicit settings persist across steps and route changes. A route with no registered adapter preserves the proposed config so an `llm/stream` listener can own and short-circuit it; unhandled terminal dispatch still fails with `NO_ADAPTER`. A new loop instance follows the same adapter-default marker rule and appends a `resume` snapshot.
 
 Plugin failure ends the current turn, not the loop. Final adapter selection, dispatch, and iteration failures arrive from `ctx.llm` as terminal error or aborted finishes and enter `agent/request-error`; middleware, result processing, tools, and other extension failures remain thrown and close directly. Recovery receives request coordinates, immutable provider facts, the immutable retry policy captured by the prepared adapter registration, and the turn signal; the policy is absent when middleware owns an unprepared route. A handling listener returns `{ kind: 'retry' }`; an unhandled failure is terminal. AgentLoop owns one cancellation signal for the current admission or turn. An effective `cancel(cause)` clears pending work unless `keepInbox` is set and cooperatively aborts that signal; idle cancellation is a no-op. Waking input that lands after the abort fires but before the activity converges to idle is latched (`wakeRequested`) and replayed at the driver's own convergence boundary, so it runs without a further waking send; a `disposed` cancel never latches, and a wake submitted while already idle always opens its turn boundary (status shows a transient `idle → running → idle` pair even when the message was cleared). Durable `turn/end` records `aborted` for `user` and `parent`, while disposal records `disposed`; undispatched model tool calls receive synthetic `tool/call` and `ABORTED_BEFORE_DISPATCH` result pairs. The cancellation cause changes reporting, not how result context finalized after cancellation is handled. Disposal waits for signal-ignoring work before registry removal. The [explicit-cancellation decision](../../../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.md) and the [cancel-convergence wake latch](../../../.agents/notes/implemented/bug-fix/2026-08-07-cancel-convergence-wake-latch.md) own the lifecycle and race contract.

 Most interception points are cooperative waterfalls. `agent/pre-step` receives a payload carrying the subject `agent`, the exclusive claimed `UserMessage[]`, and the proposed `turn`, `step`, and cancellation `signal`; its batch may be empty when tools already require another request. Agent-scoped turn extension points carry their explicit `AbortSignal` in the payload; the remaining turn-scoped extension points receive it through their request value. Listeners may cooperate with a signal but must not retain it as authority over another turn. `agent/request-error` is the failed-model-request recovery waterfall: it receives request coordinates, normalized failure facts, the serving registration's retry policy when available, and the signal. A listener returns `{ kind: 'retry' }` without calling `next()` when it owns recovery. `agent/turn-stopping` runs before an otherwise completed turn closes. The [explicit-cancellation decision](../../../.agents/notes/implemented/architecture/2026-07-16-explicit-turn-cancellation.md) owns signal lifetime; the [agent-scope runtime-design Agent Note](../../../.agents/notes/implemented/architecture/2026-07-12-agent-scope-runtime-design.md#three-execution-boundaries-are-deliberately-one-way) owns scoped dispatch and terminal settlement.

Its optional `adapterDefaults` map marks effective `reasoningEffort` or `maxTokens` values materialized by exact-model resolution, allowing the next request proposal to distinguish them from explicit conversation settings. `foldRequestHeader()` selects the latest snapshot; legacy delta events and the removed `fallback` reason are rejected. See the [reconstructable-requests Agent Note](../../../.agents/notes/implemented/architecture/2026-07-05-reconstructable-requests.md).
+`request/header` records a full canonical snapshot of the non-history request envelope with reason `initial`, `resume`, `change`, or `series`. `series` repeats an unchanged envelope when `agent/pre-step` explicitly starts a distinct model-message series or a surface replacement changes the model's message list; when that boundary coincides with an envelope change, the `change` snapshot carries `startsSeries: true` so both facts survive. Ordinary append-only later turns remain in the current series. Same-series steps and retries with an unchanged envelope keep using the latest snapshot. Repeating the complete system prompt and tool catalog grows the log linearly with message series, but keeps every header self-contained for partial-window rendering and exact request reconstruction; a lightweight reference marker would require predecessor availability and a second replay representation. Its optional `adapterDefaults` map marks effective `reasoningEffort` or `maxTokens` values materialized by exact-model resolution, allowing the next request proposal to distinguish them from explicit conversation settings. `foldRequestHeader()` selects the latest snapshot; legacy delta events and the removed `fallback` reason are rejected. See the [reconstructable-requests Agent Note](../../../.agents/notes/implemented/architecture/2026-07-05-reconstructable-requests.md).
 
 A `user/message` stores the complete `UserMessage` directly, including the identity created before inbox routing or step entry. It renders its `content` verbatim whether it is a direct human prompt, a synthetic injection, or an entered goal round; its typed `source` is the only channel that tells them apart and carries any domain-specific durable facts. `assistant/message` and `tool/result` likewise store complete message values. Turn execution remains enclosed by `turn/start` and `turn/end`; `agent.inject()` queues input until a later pre-step claims it and returns it in an enter decision.

 `user/message` 会直接存储完整的 `UserMessage`，其中包括收件箱路由或进入步骤前创建的标识。无论它是直接人类提示词、合成注入，还是已进入的 Goal Round，都会原样呈现其 `content`；带类型的 `source` 是区分三者的唯一通道，并携带各领域专有的持久事实。`assistant/message` 和 `tool/result` 也会存储完整的消息值。轮次执行仍由 `turn/start` 与 `turn/end` 包围；`agent.inject()` 会把输入排队，直到后续某次 pre-step 领取它，并在 enter 决策中返回它。

It queues one `` prompt with `GoalMessageSource`.

+When an exact live agent is idle with an active, armed goal and remaining capacity, the driver first checkpoints pending goal mutations, then reserves `roundsStarted + 1` for the current `{ goalId, revision }`. It queues one `` prompt with `GoalMessageSource`. The `agent/pre-step` listener verifies the complete claimed record and current goal both before and after downstream listeners; an accepted round sets `startsRequestSeries: true`, so that boundary is logged as `series` for an unchanged header or `startsSeries: true` on a coincident `change`. Chat renders the header before the round message to match the provider envelope order. Only an entered `user/message` increments `roundsStarted`. A reservation rejected as stale does not consume the round number.
 
 `MessageId` identifies the reserved message through durable inbox insertion and claim; it does not identify a turn result. Human messages do not consume the goal cap. If human work enters the inbox before a reservation or joins its pending batch, automatic work yields until the agent becomes idle; a pending automatic prompt in a mixed batch is rejected and re-reserved only after that checkpoint.

 `MessageId` 通过持久 inbox 插入和领取来标识预留消息；它不标识轮次结果。人类消息不消耗 goal 上限。如果人类工作在预留前进入 inbox，或加入预留的待处理批次，自动工作会让行，直到 agent 进入 idle；混合批次中的待处理自动提示词会被拒绝，只有在该检查点之后才重新预留。

+A session resolves its model selection from three tiers on every access: a selection made in this process, otherwise the session's latest logged `request/header`, otherwise this default. A session that has run a turn derives its selection from its log, while a blank session observes a default saved after it was created. A logged reasoning effort marked as an adapter default remains absent from the restored selection, so the next model resolution does not promote that default into an explicit choice or record a false header change.
 
 `session.selectModel` saves an accepted switch as the deployment default; there is no separate gesture. It stores the resolved `ModelSelection`, including an adapter-materialized default effort. The complete-section write clears a stored effort when the selected model has none. A storage failure is logged without undoing the session selection. A deployment with no settings provider keeps the composition entry and the switch remains session-local.

 Verify your work by running the code or tests. Keep answers brief and factual.
 
 
+Check the [exit code: N] marker on every bash result; investigate failures before moving on.
+
+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-observation-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-observation-policy requires it), unless you just created or edited it in this session.
+
+Use the glob tool — not shell find — to discover files by path pattern. A pattern with no "/" matches basenames at any depth, so "*" matches every file in the tree rather than its top level. Results are files only, never directories, and include hidden and ignored files: a result that fits comes back in modification-time order, while a larger one keeps the modification-time-ordered head.
+
+Use the grep tool — not shell grep or rg — to search file contents. Use read on a matched file when you need surrounding context.
+
+Track every background job id you start. You are notified in-session when a job finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running job's work. Before giving a final answer, collect every still-relevant job with job_output (set wait: true only when you are genuinely blocked on it), and job_kill jobs that stopped mattering.
+
+Use the web_search tool to discover current information on the web. The required queries array accepts 1–4 non-empty search queries; use a one-item array for a single search. It returns an optional answer plus a list of source URLs. Use the returned source snippets when available, and cite the relevant URLs as markdown links.
+
+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 subagent in the background by default. Start independent delegations together in one assistant message and continue useful work while they run. Set `run_in_background: false` only when your next action depends on that subagent's result. When a background run settles, the runtime sends you a notice containing its outcome and any final assistant message.

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under  mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a job id immediately; read its output with `job_output` and stop it with `job_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

Set `run_in_background: true` for long-running commands: the call returns a job id immediately; read its output with `job_output` and stop it with `job_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access.

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them.

+You are an AI agent powered by DeepSeek Harness.
+
+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.
+
+
+Check the [exit code: N] marker on every bash result; investigate failures before moving on.
+
+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-observation-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-observation-policy requires it), unless you just created or edited it in this session.
+
+Use the glob tool — not shell find — to discover files by path pattern. A pattern with no "/" matches basenames at any depth, so "*" matches every file in the tree rather than its top level. Results are files only, never directories, and include hidden and ignored files: a result that fits comes back in modification-time order, while a larger one keeps the modification-time-ordered head.
+
+Use the grep tool — not shell grep or rg — to search file contents. Use read on a matched file when you need surrounding context.
+
+Track every background job id you start. You are notified in-session when a job finishes — do not busy-poll or sleep on one; keep working on independent steps and do not duplicate a running job's work. Before giving a final answer, collect every still-relevant job with job_output (set wait: true only when you are genuinely blocked on it), and job_kill jobs that stopped mattering.
+
+Use the web_search tool to discover current information on the web. The required queries array accepts 1–4 non-empty search queries; use a one-item array for a single search. It returns an optional answer plus a list of source URLs. Use the returned source snippets when available, and cite the relevant URLs as markdown links.
+
+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 subagent in the background by default. Start independent delegations together in one assistant message and continue useful work while they run. Set `run_in_background: false` only when your next action depends on that subagent's result. When a background run settles, the runtime sends you a notice containing its outcome and any final assistant message.

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under  mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a job id immediately; read its output with `job_output` and stop it with `job_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them. The run executes in the foreground: this call returns when the whole script finishes.",

Each call runs in a fresh shell: no state (cwd, variables, functions) persists between calls — pass `workdir` instead of using `cd`. Non-zero exits are reported as `[exit code: N]`. Current harness environment facts are exposed through managed `$DSH_*` variables; inspect them when needed. Commands may run under a file sandbox; a blocked file operation is reported as `[sandbox: file access denied under  mode]` — a policy denial, not a bug in the command; do not retry another way. Long output is truncated to its tail; the full output is saved to a file whose path is reported when available. Set `run_in_background: true` for long-running commands: the call returns a job id immediately; read its output with `job_output` and stop it with `job_kill`. Attempting a command the sandbox may deny is safe and expected: run it and read the marker rather than assuming the denial. When a command is denied and a wider mode would let it succeed, escalate immediately in the same turn — the one sanctioned exception to a denial: retry the exact same command once with `sandbox_permissions` (the narrowest wider mode that suffices) plus a one-sentence `justification`. Do not detour through chat to ask permission first — the approval prompt raised by that retry is how the user consents. If the session states approval prompts are disabled, there is no exception: a denial is final — do not set `sandbox_permissions`. Never escalate speculatively: ground the request in a real denial — normally the one this command just hit; escalating up front is fine only when this session already denied the same access. A rejected escalation is final for that command — stop and explain, never work around it — but it does not forbid attempting or escalating other commands later.",

Use this for work that fans out across many independent pieces — an audit over many files, a migration, multi-angle research, adversarial verification of findings — where you write the orchestration as a script instead of delegating turn by turn.\n\nThe workflow's identity rides the `meta` parameter as JSON: required `name` (short kebab-case) and `description` strings, optional `whenToUse` string and `phases` array (`{title, detail?, provider?, model?}`). The `script` parameter is the plain JavaScript body ONLY (NOT TypeScript, and NO `export const meta` statement — meta is a parameter, not code), running with top-level await; end with `return ` — the value must be JSON-serializable and is this tool's result.\n\nScript-body hooks:\n- `agent(prompt, opts?): Promise` — run one subagent to completion. Without `opts.schema` it resolves to the child's final text; with `opts.schema` (an object-rooted JSON Schema using ONLY type/properties/required/additionalProperties/items/enum/const/oneOf — no pattern/format/numeric bounds) it resolves to the validated object. Resolves `null` when the child fails (filter with `.filter(Boolean)`). Other opts: `label` (display), `phase` (progress group), and independent `provider`/`model` LLM target overrides (either may be provided alone). Anything else (`effort`/`isolation`/`agentType`) is rejected loudly.\n- `pipeline(items, ...stages): Promise` — run each item through the stages independently with NO barrier between stages (prefer this for multi-stage work). Each stage receives `(prev, item, index)`. An ordinary stage throw drops that ITEM to `null` and skips its remaining stages.\n- `parallel(thunks): Promise` — run zero-argument functions concurrently and await ALL of them (a barrier; use only when a stage genuinely needs every prior result together). A throwing thunk resolves to `null`.\n- `phase(title)` — start a progress phase; `log(message)` — narrate progress; `args` — the tool call's `args` input, verbatim.\n\nMisused hooks (bad arguments, unknown options, unsupported schemas, tripped caps) throw errors that ALWAYS kill the script — they never dissolve into a per-item `null`.\n\nConstraints: concurrency and total-agent caps apply; no filesystem, network, timers, or Node.js APIs are provided — the agents do the work, the script only coordinates them. The run executes in the foreground: this call returns when the whole script finishes.",

@@ -14,21 +14,13 @@ Session logs must be upgradable after release, and the runtime that ships first
 
 **The writer decides bumps, not the reader.** A bump is required exactly when an old runtime could no longer handle a new log with full semantic correctness. "Parses without error" is not the bar: silently skipping content that shapes reconstruction is a wrong read. Only structural changes qualify — header shape, event envelope, core event semantics, the surface mechanism (`SurfaceEventType` set, `SurfaceOp` variants). When unsure, bump: a near-identity upgrader is almost free, a missed bump silently corrupts old readers.
 
-**Read rules by direction.** Equal version: decode normally. Newer than the reader: refuse, name the direction ("written by a newer harness — upgrade"), and point at the raw log artifact so the user can still see the text (`SessionFormatUnsupportedError`, distinct from `SessionPersistenceCorruptionError` because nothing is damaged). Older than the reader: require a complete chain of static n→n+1 `SessionFormatMigration` classes; a missing migration refuses the read and names the gap. The registry is part of the build rather than Cordis composition, so one build has the same durable read capability under every plugin set.
-
-**Format migration is the decoder, not a Coordinator repair branch.** Backends expose parsed durable data as `unknown` through a repeatable `StoredSessionSource`: one raw header, one exact revision, and `readEvents()` factories that create independently consumable `AsyncIterable` streams bound to that revision. Each migration class carries static adjacent `from`/`to` versions. One fresh instance handles one decode attempt: `header()` runs once, `event()` maps each input record to exactly one lossless-JSON output with the same seq, and optional `finish()` validates accumulated state after EOF. Instance fields may retain header and earlier-event facts without sharing state across sessions, concurrent reads, or revision retries. Header-only reads stop after `header()` and never call `finish()`, so that method validates EOF state rather than releasing resources. Any version conversion reads the complete event stream and applies the requested suffix only after all migrations; an equal-version read retains backend suffix seek. The decoder validates each output header version and each migration's seq preservation, then applies current `SessionHeader` and `SessionEvent` validation only after the complete chain.
-
-**A future format bump adds one format-owned migration.** The change adds `format-migrations/vN-to-vN+1.ts`, exports its class from the static `SESSION_FORMAT_MIGRATIONS` array, and increments `SESSION_FORMAT_VERSION`. The migration owns every old header and event variant it accepts, its instance state, and explicit failure for malformed input. It cannot add, remove, reorder, or renumber events: durable references use seq as event identity. A format change that alters facts consumed by a projection increments that projection's `stateVersion`; unchanged projections retain their cache rows. Backends and the Coordinator do not gain version-specific branches. Historical variants that never changed the version remain isolated in the format-v0 compatibility decoder and are not a template for later version migrations. This decoder maps the historical `compact/start`, `compact/summary`, `compact/end`, and `compact/prune` names to canonical `compaction/*` events while preserving the rest of each record.
-
-**Recovery and writeback consume current-format data.** `inspect()` and `readFrom()` decode only in memory. Cold `prepare()`/`load()` first decode the whole source, add the current recovery closers, and replace the exact old revision with that complete balanced current-format stream. Live HMR adoption uses the same replacement primitive after seed verification but does not synthesize closers for a turn still owned by the live Session. A successful replacement or revision conflict discards the prepared object and reopens the stored source before continuing.
-
-**Replacement is an internal backend compare-and-swap.** `replaceStored(expectedRevision, meta, events)` accepts a streaming current-format log and checks storage identity plus the source revision at the commit boundary. JSONL writes and fsyncs a sibling temporary artifact, rechecks the source revision immediately before the atomic replace, atomically replaces the path (using the Windows write-through replacement primitive there), and syncs the parent directory on POSIX; like every other coordinator freshness check, the recheck adds no cross-process writer exclusion — JSONL assumes one live writer per session. SQLite stages the event iterator, then rechecks and replaces the header and event rows in one transaction. A failed commit leaves one complete old or new log; retaining a permanent pre-upgrade copy is a separate recovery policy, not part of the format migration API.
+**Read rules by direction.** Equal version: read normally. Newer than the reader: refuse, name the direction ("written by a newer harness — upgrade"), and point at the raw log artifact so the user can still see the text (`SessionFormatUnsupportedError`, distinct from `SessionPersistenceCorruptionError` because nothing is damaged). Older than the reader: convert in memory through the chain of n→n+1 upgraders for viewing; persist the converted log only when the session is actually continued (atomic temp-file replace, original kept as backup). A step whose upgrader cannot be written is left empty, which cuts off every version at or below it — those degrade to raw-text viewing.
 
 **A per-event `ignorable` marker covers vocabulary growth, so ordinary event additions never bump the version.** The event vocabulary is decided by which plugins are mounted, which a single version integer cannot describe. A reader meeting an unrecognized event type refuses to interpret the log unless the event carries `ignorable: true` in its envelope. The default is *required*: forgetting the marker over-refuses a resumable session (an inconvenience), while a default of ignorable would make the same mistake silently resume a gutted one (a safety failure). The architecture makes this sound: model-visible content flows only through the three `surfaceOp`-marked surface event types plus the `request/header`/`request/context` folds, so the dangerous unknowns are exactly the non-surface events that change how the rest of the log is read (`session/end-seed` is the existing example).
 
 ## Consequences
 
-Format v0 carries direction-aware refusal with the raw-log path; the unknown-event guard against a generated known-vocabulary list (`KNOWN_SESSION_EVENT_TYPES`, emitted by `gen-persistence-catalog` from every `SessionEventMap` merge and kept fresh by `verify-persistence-catalog`); the `ignorable` envelope field accepted by seed validation, both backends (a dedicated SQLite column, `SCHEMA_VERSION` 15), and the BFF wire schema; and the static streaming migration decoder with an empty adjacent-version registry. `SESSION_FORMAT_VERSION` remains 0 until a real v0→v1 step lands. The decoder and backend replacement APIs therefore have direct tests without manufacturing a format bump. Writers do not yet set `ignorable` because no producer needs it. Until a registration surface exists, an out-of-repo plugin's events refuse resume under first-party readers; the refusal is loud rather than silent. The unknown-type guard is read-side only: `appendCore` keeps rejecting retired legacy shapes but does not vocabulary-check new types, because an append-time refusal would stall a live session's durability mid-flight, which costs more than a loud refusal at the log's next load. The JSONL backend additionally refuses a foreign version from the raw header line before validating today's header fields or decoding any event record, so a structurally different future format still reports the upgrade direction instead of "corrupt"; SQLite gates whole-file structure through its own `SCHEMA_VERSION` pragma first.

The upgrader chain itself is deferred until the first real v0→v1 step exists to test it against; writers do not yet set `ignorable` (no producer needs it), so `Session.append` gains that surface with its first user.

 - **Per-plugin runtime registration of known event types** — would make the known set composition-dependent, so a leaner same-version composition would refuse logs a fuller one wrote.

Repeatable revision-bound readers plus one-at-a-time event transforms preserve retry semantics without imposing that allocation.

 **升不升版本由写入方决定，与读取方能力无关。**当且仅当老运行时无法在语义上完全正确地处理新日志时才必须升版本。"解析不报错"不是标准：静默跳过影响重建的内容就是读错。只有结构性变更够得上这条线：header 形状、事件信封、核心事件语义、surface 机制（`SurfaceEventType` 集合、`SurfaceOp` 变体）。拿不准就升：近似恒等的升级器几乎没有成本，漏升一次会让老读取器静默读坏。
 
-**读取规则按方向区分。**版本相等：正常解码。比读取器新：拒绝，说明方向（"由更新的 harness 写入，请升级"），并给出原始日志文件的路径，用户仍能看到文本（`SessionFormatUnsupportedError`，与 `SessionPersistenceCorruptionError` 区分，因为数据没有损坏）。比读取器旧：要求静态 n→n+1 `SessionFormatMigration` 类组成完整链路，缺失任何 migration 都会拒绝并指出断点。注册表属于 build 而不是 Cordis composition，因此同一个 build 在任何插件组合下都具有相同的持久化读取能力。
-
-**格式迁移就是 decoder，不是 Coordinator 的修复分支。**后端通过可重复读取的 `StoredSessionSource` 把解析后的持久化数据作为 `unknown` 暴露：一个原始 header、一个精确 revision，以及每次产生独立 `AsyncIterable` 且绑定该 revision 的 `readEvents()` factory。每个 migration class 用静态且相邻的 `from`／`to` 标识版本。每次 decode 都创建一个新实例：`header()` 调用一次；`event()` 把每条输入记录映射为一条 seq 相同、可无损表示为 JSON 的输出；可选的 `finish()` 在 EOF 后验证累计状态。实例字段可以保留 header 与之前事件的事实，而不会在 Session、并发读取或 revision retry 之间共享状态。只读 header 时在 `header()` 后结束，绝不调用 `finish()`，因此该方法用于验证 EOF 状态而不是释放资源。只要发生版本转换，就读取完整事件流，并在所有 migration 完成后才应用请求的 suffix；版本相等时仍保留 backend suffix seek。Decoder 验证每一步输出的 header version 和每个 migration 是否保持 seq，完整链路结束后才执行当前 `SessionHeader` 和 `SessionEvent` 校验。
-
-**以后每次 format bump 只增加一个格式 migration。**改动新增 `format-migrations/vN-to-vN+1.ts`，把它的 class 导出到静态 `SESSION_FORMAT_MIGRATIONS` 数组，并递增 `SESSION_FORMAT_VERSION`。Migration 自己负责它接受的所有旧 header 和 event 变体、实例状态，以及对畸形输入的明确失败。它不能增加、删除、重排事件或重编号：持久引用以 seq 作为事件身份。如果格式变化影响了某个 projection 消费的事实，就递增该 projection 的 `stateVersion`；未受影响的 projection 保留 cache 记录。Backend 和 Coordinator 不增加版本特判。没有改变版本号的历史变体继续隔离在 format-v0 compatibility decoder 中，不作为后续版本 migration 的模板。该 decoder 将历史 `compact/start`、`compact/summary`、`compact/end`、`compact/prune` 名称映射为规范的 `compaction/*` 事件，并保留每条记录的其余内容。
-
-**Recovery 和写回只消费当前格式数据。**`inspect()` 和 `readFrom()` 只在内存中解码。Cold `prepare()`/`load()` 先解码完整 source，补充当前 recovery closers，再用完整、平衡的当前格式 stream 替换精确的旧 revision。Live HMR adoption 在 seed 校验后使用同一个 replacement primitive，但不会为仍由 live Session 掌握的 turn 合成 closer。替换成功或 revision 冲突后都会丢弃 prepared object，重新打开持久化 source 后再继续。

 **逐事件的 `ignorable` 标记吸收词汇表增长，普通的新增事件永远不用升版本。**事件词汇表由挂载了哪些插件决定，单个版本整数描述不了它。读取器遇到不认识的事件类型时拒绝解读日志，除非该事件的信封带 `ignorable: true`。默认为必需：忘写标记的后果是把一个本可恢复的会话拒绝过头（体验问题），而默认可忽略会让同样的疏忽静默恢复出残缺会话（安全事故）。架构保证了这条规则成立：模型可见内容只经三种带 `surfaceOp` 标记的 surface 事件加 `request/header`、`request/context` 折叠进入重建，危险的未知事件恰好是那些不进 surface 但改变日志其余部分解读方式的事件（`session/end-seed` 是现存例子）。

 ## Format refusal — logs a build cannot faithfully read
 
-A backend refuses a log it cannot faithfully interpret with `SessionFormatUnsupportedError`, distinct from `SessionPersistenceCorruptionError` because nothing is damaged. A header `version` ahead of `SESSION_FORMAT_VERSION` names the direction ("written by a newer harness — upgrade the harness to open it"); one behind it requires a complete registered adjacent-version migration path or names the missing step. After legacy-shape normalization, an event type outside this build's generated vocabulary (`KNOWN_SESSION_EVENT_TYPES`, emitted by `gen-persistence-catalog`) refuses the same way unless the event's envelope carries `ignorable: true` — silently skipping an unrecognized required event could change how the rest of the log must be read. The message appends the raw log path when the backend keeps one artifact per session, so the refused text stays reachable. The JSONL backend refuses a foreign version straight from the raw header line, before validating today's header shape or decoding any event row — a structurally different future format still reports the upgrade direction, never "corrupt"; SQLite gates whole-file structure through its own `SCHEMA_VERSION` pragma first. Design rationale lives in the [session-log-version-mechanism note](../../.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.md).

-## `SessionFormatMigration` — adjacent static format upgrades

-Each migration class declares one adjacent `from`/`to` pair and creates fresh state for one decode attempt. The decoder snapshots every header and event output as detached lossless JSON before the next migration receives it, preserves event sequence numbers, and calls optional EOF validation only after the complete event stream is consumed. The [package README](../../packages/session/session-persistence/README.md) owns the registration and version-bump procedure.

 Each `session/event` copies its event into the session controller. The first pending event starts a fixed batching window; later events join without resetting its deadline. The configured `writeBatchMaxDelayMs` bounds this intentional wait, not event-loop, initialization, serialized-operation, or backend latency. Events admitted during a write form a new bounded batch. `session/flush` cancels the wait and is a shared quiescence barrier that drains events admitted while it runs. A background failure is logged once, retains the ordered batch, and pauses automatic retry; a new event starts a fresh window, while explicit flush or backend teardown retries immediately and surfaces a repeated failure.

HMR adoption opens the same revision-bound source, applies the coordinator's cwd check, and never closes the active turn.

-## Format decoding and upgrades
-
-Every logical read opens a repeatable `StoredSessionSource` containing an untrusted header, an exact revision, and a `readEvents()` factory. The static decoder chooses a complete adjacent-version path, creates one migration instance per version, calls `header()` once, calls `event()` once per input record, and calls optional `finish()` after EOF. It then validates the final header and events as the current format. `inspect()` and `readFrom()` do not write. Cold continuation and live adoption replace a converted source through the backend's revision compare-and-swap, then reopen it; a concurrent change discards the decoded result and restarts from the new source. The [session-log versioning Agent Note](../../../.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.md) owns the rationale and refusal rules.
-
-A future vN→vN+1 change adds `src/format-migrations/vN-to-vN+1.ts`, exports its class from the static `SESSION_FORMAT_MIGRATIONS` array, and increments `SESSION_FORMAT_VERSION`. Static `from`/`to` identify adjacent versions; instance fields retain header and cross-event state. `header()` validates and converts the old header, `event()` returns exactly one lossless-JSON event with the input event's seq, and optional `finish()` validates state that can be settled only at EOF. Header-only reads do not call `finish()`. A migration that changes facts consumed by a projection also increments that projection's `stateVersion`; persistence does not invalidate every projection cache entry. Backends and the coordinator remain version-independent.
-
-The v0 decoder also recognizes the bounded pre-versioning variants recorded by the [pre-identity message](../../../.agents/notes/implemented/bug-fix/2026-07-28-load-pre-identity-session-messages.md) and [pre-react-loop session](../../../.agents/notes/implemented/bug-fix/2026-08-04-load-pre-react-loop-sessions.md) decisions, and normalizes the historical `compact/start`, `compact/summary`, `compact/end`, and `compact/prune` names to their canonical `compaction/*` names. These compatibility transforms are not format migrations.
+Backend reads convert the exact supported older records from the same format version before validating current records. Pre-identity messages receive the deterministic id `legacy-message::`; a tool-result content replacement inherits its target's imported id. A pre-react-loop `turn/start` loses its obsolete trigger, a removed `steering/message` becomes the same identified `user/message`, and an older `turn/end` maps its terminal reason without inventing a caller that the old record did not name. The coordinator uses the same converted view for `load`, `inspect`, `readFrom`, ownerless-state claims, and HMR prefix adoption. Storage remains append-only: reads do not rewrite old records, and later appends use the current format. These are narrow import exceptions from the [pre-identity message](../../../.agents/notes/implemented/bug-fix/2026-07-28-load-pre-identity-session-messages.md) and [pre-react-loop session](../../../.agents/notes/implemented/bug-fix/2026-08-04-load-pre-react-loop-sessions.md) decisions, not a general v0 migration promise.
 
 When a live session emits `session/disposed`, the coordinator waits for its controller, serializes a final drain, then releases state owned by that exact `Session` object. Failed retirement leaves the controller in the live-session map, so backend teardown can retry it. Backend teardown stops event admission first, flushes every remaining controller, awaits per-id operations, and only then closes the storage handle.

-## 格式解码与升级

-每次逻辑读取都会打开可重复使用的 `StoredSessionSource`，其中包含不可信 header、精确 revision 和 `readEvents()` factory。静态 decoder 选择完整的相邻版本路径，为每个版本创建一个 migration 实例，调用一次 `header()`，为每条输入记录调用一次 `event()`，并在 EOF 后调用可选的 `finish()`，最后按当前格式验证 header 与事件。`inspect()` 和 `readFrom()` 不写存储；冷 continuation 与实时接管通过后端的 revision compare-and-swap 替换已转换 source，然后重新打开。并发变更会丢弃解码结果，并从新 source 重新开始。[Session log 版本机制 Agent Note](../../../.agents/notes/implemented/architecture/2026-08-10-session-log-version-mechanism.zh.md)规定其原因和拒绝规则。
-
-以后新增 vN→vN+1 时，在 `src/format-migrations/vN-to-vN+1.ts` 添加 class，从静态 `SESSION_FORMAT_MIGRATIONS` 数组导出，并递增 `SESSION_FORMAT_VERSION`。静态 `from`／`to` 标识相邻版本，实例字段保留 header 和跨事件状态。`header()` 验证并转换旧 header；`event()` 只返回一条可无损表示为 JSON 且 seq 与输入相同的事件；可选的 `finish()` 验证只能在 EOF 时结算的状态。只读 header 时不调用 `finish()`。如果 migration 改变了某个 projection 消费的事实，还要递增该 projection 的 `stateVersion`；persistence 不统一作废所有 projection cache 记录。后端和协调器不增加版本特判。

+后端读取会在验证当前记录前，转换同一格式版本中明确受支持的旧记录。消息标识机制引入前的消息会获得确定性的 id `legacy-message::`；工具结果的内容替换会继承其目标导入后的 id。react-loop 引入前的 `turn/start` 会移除过时的 trigger，已移除的 steering（中途引导）事件 `steering/message` 会转换为同一条带标识的 `user/message`；旧版 `turn/end` 会映射终止原因，但不会虚构旧记录中没有记载的调用方。协调器对 `load`、`inspect`、`readFrom`、无所有者状态的认领和 HMR 前缀接管使用同一份转换后视图。存储仍然仅追加：读取不会重写旧记录，此后追加的事件使用当前格式。这些是[消息标识机制引入前的消息](../../../.agents/notes/implemented/bug-fix/2026-07-28-load-pre-identity-session-messages.zh.md)与 [react-loop 引入前会话](../../../.agents/notes/implemented/bug-fix/2026-08-04-load-pre-react-loop-sessions.zh.md)决策所规定的范围受限的导入例外，并不构成通用的 v0 迁移承诺。
 
 活动会话发出 `session/disposed` 时，协调器等待其 controller，以串行方式执行最终 drain，然后释放该精确 `Session` 对象拥有的状态。失败退役会将 controller 保留在活动会话 map 中，使后端拆卸可重试。后端拆卸先停止事件接纳，flush 每个剩余 controller，等待每 id 操作，最后才关闭存储句柄。

Subject: [PATCH 52/76] ci(windows): raise coverage test timeout to 60s

After the 4-partition split, other PRs' windows coverage now fails on
process-bound subagent-acp tests timing out at 30s under self-hosted
concurrency. Give the coverage lane the same 60s per-test budget that the
earlier failover profile used.

Subject: [PATCH 55/76] test(subagent-acp): double the per-test timeout
 relative to default

These tests spawn real ACP child subprocesses. On contended self-hosted
Windows runners the default 30s budget times out. Instead of raising the
global coverage timeout, give this file 2x the configured default
(DSH_COVERAGE_TEST_TIMEOUT_MS) so it follows future default changes.

 Windows

Windows anonymous pipes do not surface a child stdout EOF while the child
process stays alive. The three tests that simulate 'child closes protocol but
stays alive' therefore cannot be reproduced on Windows and hang until the
test timeout. Skip them on win32.

 `@deepseek-ai/dsh-tool-bash-persistent` consumes `ctx.terminals` and registers one `bash(command)` tool. It lazily creates one interactive shell per exact Agent and serializes that owner's calls. Cwd, exported variables, activated environments, functions, and background jobs persist. Random private markers delimit command output. Retained scrollback is paged backward to recover the command's original prefix; a dropped prefix is reported explicitly. A nonzero wrapped command appends `[exit code: N]`; a shell that dies before reporting that status instead appends `[shell exited: code N]`, `[shell killed by signal: SIG]`, or `[shell exited]` when the backend supplies neither. `maxOutputChars` bounds retained command output, while fixed diagnostics can extend the returned string. Timeout or cancellation closes the shell before another call can reuse uncertain state, and model-visible timeout/exit results disclose that reset. Cancellation always resets and discards the result, even when a complete status marker is already observable, so state changes the model never saw cannot survive. The configurable description defaults to persistence facts only, so network and package-mirror claims remain deployment-owned.
 
-`@deepseek-ai/dsh-tool-str-replace-editor` independently consumes `ctx.fs` and registers `str_replace_editor` with `view`, `create`, `str_replace`, and `insert`. It provides numbered text views, filtered two-level directory listings, unique literal replacement, canonical insertion boundaries, and bounded output. Paths are absolute; file views preserve content tabs so copied text remains valid literal replacement input; mutations preserve tabs outside the requested edit; and the public schema and failures use only `old_str`. The plugin can compose with persistent Bash, one-shot Bash, sandboxed Bash, or no shell.

The plugin can compose with persistent Bash, one-shot Bash, sandboxed Bash, or no shell.
 
 `dsh-system-prompt` accepts `includeHarnessIdentity: false`, while `dsh-agent-spine-demo` forwards that setting and accepts `toolBash: false`.

 ## Consequences
 
-Profiles can reproduce an external agent by configuring persona and descriptions while the underlying packages remain general. Persistent Bash requires an owning Agent and real PTY backend. Shell exit, timeout, or cancellation loses state. The editor delegates security and mutation policy to the mounted filesystem stack. A minimal Web agent retains Web permissions but must close its persistent shell before changing modes. Runtime-wheel consumers still need no Node installation; Linux wheels contain one executable, while macOS wheels also contain its private native helper.

 ## Tool
 
-The schema provides `view`, `create`, `str_replace`, and `insert` over absolute paths. File views use one-based line numbers and preserve content tabs, so displayed text remains valid literal replacement input; directory views omit hidden, dependency, and Python-cache entries and descend two levels. A metadata miss from `view`, `str_replace`, or `insert` records confirmed absence before returning `FS_NOT_FOUND`, so a later `create` can recover an externally deleted path through the mounted policy's guarded-create flow; absence never authorizes `str_replace` or `insert`. Replacement requires one unique literal match and reports errors only in the public `old_str` vocabulary. Insert follows the selected zero-based insertion boundary without adding an implicit trailing newline. Mutations preserve tabs outside the requested edit.

   /** Delegate a self-contained task to a subagent (a separate agent that works in its own context) to offload focused, independent work — research, a scoped implementation, an analysis — so it does not consume this conversation's context. The subagent returns its result, not its intermediate steps. Give it a complete, standalone prompt: it does not see this conversation. This tool runs in the background by default, immediately returns a durable subagent id, and keeps the child conversation available for later turns. When that run settles, the runtime sends the parent a notice containing its outcome and any final assistant message; `send_message` starts a later turn in the same child conversation. Set `run_in_background: false` only when your next action depends on receiving the result. Child LLM selection is optional. Omit `provider`, `model`, and `reasoning_effort` to use configured child defaults and inherit compatible missing values from the parent Agent. Supply `provider` and `model` together after using `list_subagent_models` to inspect advertised routes and efforts. Changing the effective route without naming an effort uses the selected model's default effort. */

   /** Delegate a self-contained task to a subagent (a separate agent that works in its own context) to offload focused, independent work — research, a scoped implementation, an analysis — so it does not consume this conversation's context. The subagent returns its result, not its intermediate steps. Give it a complete, standalone prompt: it does not see this conversation. This tool runs in the background by default, immediately returns a durable subagent id, and keeps the child conversation available for later turns. When that run settles, the runtime sends the parent a notice containing its outcome and any final assistant message; `send_message` starts a later turn in the same child conversation. Set `run_in_background: false` only when your next action depends on receiving the result. Child LLM selection is optional. Omit `provider`, `model`, and `reasoning_effort` to use configured child defaults and inherit compatible missing values from the parent Agent. Supply `provider` and `model` together after using `list_subagent_models` to inspect advertised routes and efforts. Changing the effective route without naming an effort uses the selected model's default effort. */

 ## Problem
 
-The `headless` product contract is one local task with final assistant text on stdout, a success-sensitive exit code, empty stderr on success, and no listening port. A composition containing Workspace Host services, ApiProxy, HTTP, the Web runtime, or browser plugins contradicts that contract and makes local completion depend on an unrelated transport tree.

A composition containing Workspace Host services, ApiProxy, HTTP, the Web runtime, or browser plugins contradicts that contract and makes local completion depend on an unrelated transport tree.
 
 The direct entry point still needs the same deployment model state as Web-created Agents. A separate provider/model default would give one deployment two answers, while deriving completion before the Agent and Session persistence are quiescent permits stdout and the exit code to observe incomplete state.

 The shipped `headless` profile contains `dsh-base` and `dsh-headless`. The base supplies the disabled module-HMR default; the headless bundle supplies its persona and tool mode, mounts the Code Mode worker explicitly, and inserts `headless-runner` without overriding that policy. Its tree contains no `@deepseek-ai/dsh-host-*` package, ApiProxy, HTTP server, Web runtime, or browser client. Code Mode and Session persistence are one-shot Agent capabilities independent of Web presentation.
 
-`headless-runner` is a direct core entry point. After Loader settlement, it reads `ctx.agentDefaultModel.currentSelection()`, creates a fresh persisted Agent through `ctx.agents.create`, installs that `ModelSelection` in the Agent scope, waits for startup quiescence, anchors the Session sequence, submits one ordinary user message, and waits for quiescence again. It awaits `ctx.sessions.flush`, folds its durable event interval for the last non-empty assistant text and final `turn/end` reason, writes the text plus one newline to stdout, and requests bounded launcher shutdown with exit 0 exactly when the reason is `completed`. A terminal `error` reason writes its durable code and message to stderr; unexpected driver failures also use stderr and exit 1.

 `@deepseek-ai/dsh-agent-default-model` owns the transport-independent default used for an Agent without a session-local selection. `AgentDefaultModelConfig` provides `ctx.agentDefaultModel` and registers the `agent-default-model` Settings section. Composition config supplies `{provider, model}`; user settings may also supply `reasoningEffort`. `currentSelection()` returns the live complete selection and `saveSelection()` writes it as a complete section, so a selection without an effort clears any stored effort. `dsh-base` supplies the composition entry. Direct and ApiProxy entry points consume this service; ApiProxy alone owns session-local precedence, model validation, and persistence of accepted Web selections.
 
 `loadProfile` recognizes the exact installation-owned headless tuple (`dsh-base`, `dsh-web-app`, `dsh-headless`) and normalizes it to the shipped headless template while preserving every other manifest field. Extra, missing, or reordered bundle lists are user-owned and remain untouched.

 ## Verification
 
-Package tests use the real Session store and Agent registry around a scripted Agent factory to pin idle-to-idle aggregation, late asynchronous completion, terminal model diagnostics, other non-completed exits, direct failures, Loader-time disposal, and flush-before-exit ordering. The keyless assembled snapshots drive `dsh --profile headless` through a replayed tool round trip, record a `user/message` with `source.kind: 'user'`, and expose a terminal model failure on stderr. Built-bin acceptance reaches a mock provider through the published entry and requires final text on stdout, exit 0, and empty stderr. Config-dump acceptance excludes every Host, Web, and Client package from the shipped headless tree; PTY shutdown coverage requires no observation line and bounded disposal.

 ## Consequences
 
-`dsh --profile headless` provides a local Agent task rather than browser observation, Host APIs, or HTTP. Users who need those capabilities choose `dsh web`. Successful stderr is empty, completion follows durable flush, and the persisted Session remains available to later tooling. Its initial user message records `source.kind: 'user'` and therefore carries no ApiProxy `rpcId`.

+# Agent Note: headless streams provider reasoning to stderr
+
+Status: implemented
+
+English | [中文](2026-08-21-headless-reasoning-progress.zh.md)
+
+## Problem
+
+The one-shot headless runner waits for complete Agent quiescence before printing the final assistant text. Reasoning-capable providers already expose their reasoning as durable `assistant/chunk` events, but a long reasoned response leaves the terminal silent until the run completes. The final answer must remain the only stdout payload so command substitution and other consumers keep a stable result channel.
+
+The earlier [direct core entry-point decision](../architecture/2026-08-09-headless-direct-core-entry-point.md) required empty stderr on every successful run. That clause prevents live reasoning progress and is superseded by this note; its transport, durability, and completion decisions remain unchanged.
+
+## Decision
+
+`headless-runner` observes the exact Session it creates after startup quiescence and before submitting the task. Once the owned interval opens with `turn/start`, each non-empty `assistant/chunk.reasoning-delta` is written immediately to stderr. A contiguous reasoning phase starts with `dsh: reasoning:` on its own line; deltas retain provider order without token-boundary decoration. The first later non-reasoning chunk, a new turn, or listener disposal terminates the phase with one newline when the provider supplied none.
+
+This output is a transient projection of the existing durable Session event stream. The runner still derives final text and exit status from the flushed log rather than from progress-presentation state. The LLM adapter, agent loop, Session event types, persistence format, and SDK projections do not change.
+
+Reasoning progress is not TTY-gated and has no separate flag. A redirected stderr stream and a supervisor receive the same provider-reported content as an attached terminal. A successful run without reasoning still writes nothing to stderr; terminal model and driver errors keep their existing `dsh:` diagnostics after any open reasoning phase is terminated.
+
+## Verification
+
+The package test holds the Agent active after a reasoning delta and observes stderr before idle, then pins newline ownership for provider-terminated and unterminated phases plus terminal errors. The keyless product snapshot drives the shipped headless profile through a reasoning-plus-tool round and pins both stderr and the persisted Session. Built-bin acceptance sends `reasoning_content` through the native DeepSeek SSE adapter and requires reasoning on stderr while stdout remains the final answer.
+
+## Alternatives considered
+
+**Dump reasoning after quiescence.** Folding reasoning from the persisted log would preserve content but leave the terminal silent during the long-running interval that motivates the feature.
+
+**Wrap the LLM stream.** Tapping `ctx.llm.stream()` would place a presentation concern in the request path and duplicate the authoritative chunks that the agent loop already appends to the Session.
+
+**Print a spinner or periodic heartbeat.** A timer reports process liveness rather than provider progress, adds an interval policy, and still hides reasoning that the provider already supplies. Time before the first reasoning delta remains silent and can be addressed separately if providers buffer their first token.
+
+**Enable output only on a TTY or explicit flag.** Headless runs under CI and supervisors need the same progress signal, while implicit TTY-dependent behavior makes redirected runs differ from interactive runs. Callers that do not want reasoning logs redirect stderr.
+
+## Consequences
+
+Reasoning-capable successful runs now write provider-reported content to stderr, so log collectors may retain substantially more and potentially sensitive model output. Stdout remains one final assistant result, text-only success keeps stderr empty, errors remain line-separated, and no new configuration or durable format is introduced. Silence before the provider emits its first non-empty reasoning delta remains an explicit limitation.

+# Agent Note: headless 将提供方推理流式写入 stderr
+
+Status: implemented
+
+[English](2026-08-21-headless-reasoning-progress.md) | 中文
+
+## 问题
+
+一次性 headless runner 会等待 Agent（智能体）完全停稳，再打印最终 assistant 文本。具备推理能力的提供方已经把推理作为持久化的 `assistant/chunk` 事件暴露，但耗时较长的推理响应会让终端在运行完成前始终保持静默。最终答案必须继续作为 stdout 中唯一的载荷，使命令替换和其他消费方保持稳定的结果通道。
+
+此前的[直接使用核心服务入口决策](../architecture/2026-08-09-headless-direct-core-entry-point.zh.md)要求每次成功运行都保持 stderr 为空。该条款会阻止实时推理进度，因此由本 Agent Note 取代；其中关于传输、持久性与完成状态的其他决策保持不变。
+
+## 决策
+
+`headless-runner` 在启动工作完全停稳后、提交任务前，观察其创建的精确 Session。自身持有的区间以 `turn/start` 打开后，每个非空的 `assistant/chunk.reasoning-delta` 都会立即写入 stderr。一段连续推理以独占一行的 `dsh: reasoning:` 开始；各分片保持提供方顺序，不添加 token 边界装饰。之后出现首个非推理分片、新轮次或 listener dispose（资源释放）时，如果提供方没有输出末尾换行，runner 会用一个换行终止该段。
+
+该输出是既有持久化会话事件流的瞬时投影。runner 仍从 flush 后的日志而不是进度呈现状态推导最终文本与退出状态。LLM（大语言模型）适配器、agent loop（智能体循环）、Session 事件类型、持久化格式与 SDK 投影均不改变。
+
+推理进度不按 TTY 启用，也没有单独 flag。重定向的 stderr 流与监督进程会收到和已连接终端相同的提供方报告内容。没有推理内容的成功运行仍不会写入 stderr；终止态模型错误与驱动器错误继续在任何已打开推理段终止后输出既有的 `dsh:` 诊断。
+
+## 验证
+
+包测试在推理分片后保持 Agent 活跃，并在 idle 前观察 stderr；测试同时固定由提供方终止和未终止的推理段换行归属，以及终止态错误。无密钥产品快照通过包含推理与工具调用的轮次驱动随附 headless profile，并固定 stderr 与持久化 Session。构建后二进制验收通过原生 DeepSeek SSE（Server-Sent Events）适配器发送 `reasoning_content`，要求推理出现在 stderr，同时 stdout 仍只包含最终答案。
+
+## 考虑过的替代方案
+
+**完全停稳后再输出推理。** 从持久化日志折叠推理能够保留内容，但在导致本功能产生的长时间运行区间内，终端仍会保持静默。
+
+**包装 LLM 流。** 截取 `ctx.llm.stream()` 会把呈现职责放入请求路径，并重复处理 agent loop 已经追加到 Session 的权威分片。
+
+**打印 spinner 或周期性心跳。** 定时器报告的是进程存活状态，而不是提供方进度；它还会新增间隔策略，并继续隐藏提供方已经给出的推理。首个推理分片前的时间仍保持静默；如果提供方会缓冲首个 token，可以另行处理。
+
+**仅在 TTY 或显式 flag 下启用输出。** CI 与监督进程中的 headless 运行需要相同的进度信号，而隐式依赖 TTY 会让重定向运行与交互式运行产生差异。不需要推理日志的调用方可以重定向 stderr。
+
+## 后果
+
+具备推理能力的成功运行会把提供方报告的内容写入 stderr，因此日志收集器可能保留明显更多且可能敏感的模型输出。stdout 仍只包含一个最终 assistant 结果，没有推理内容的成功运行保持 stderr 为空，错误继续与推理内容分行，并且本决策不引入新配置或持久化格式。提供方发出首个非空推理分片前保持静默，这是明确的限制。

 The dsh one-shot bundle. [`cordis.patch.yml`](cordis.patch.yml) rides directly over [`dsh-base`](../base/README.md): it inherits the base's disabled module-HMR policy, supplies the coding persona and tool mode, mounts Code Mode's worker as a core execution capability, and inserts this package's `headless-runner` plugin (config `{task}`, resolved from the injected `headlessStartup` provider). It mounts no Host, HTTP server, Web runtime, or browser plugin.
 
-After the Loader settles, the runner reads the shared [`ctx.agentDefaultModel`](../../core/agent-default-model/README.md), creates one fresh persisted Agent through `ctx.agents`, submits the task as an ordinary user message, and waits for quiescence. It flushes the Session before folding the owned durable event interval, writes the last non-empty assistant text to stdout, and requests exit through the launcher-provided `ctx.appExit` host hook ([`dsh-cmdline`](../../boot/cmdline/README.md)) (final `turn/end` completed → 0, otherwise 1). A terminal `error` reason also writes its code and message to stderr; successful runs keep stderr empty. The process opens no listening port. The task text is this app's command line: the ordinary `headless-startup` provider ([`src/startup.ts`](src/startup.ts)) injects `ctx.cmdlineArgs` ([`dsh-cmdline`](../../boot/cmdline/README.md)), reads the positional argument of `dsh --profile headless "task"`, prints the app's `--help`, and provides `headlessStartup`; the runner injects that service and reads its task from lazy config. A missing or whitespace-only task is rejected before the runner activates.

 ## Known Limitations and Deferred Work
 
 - **One submitted task only** — the runner has no interactive follow-up surface; it waits through any work the Agent completes before returning to idle and prints the last non-empty assistant message in that interval.
+- **No pre-token heartbeat** — stderr remains silent until the provider emits a non-empty reasoning delta; a provider that delays its first streamed token exposes no earlier progress signal.
 - **`ctx.appExit` is launcher-owned** — booting the headless profile outside the `dsh` launcher fails loud at activation until the host provides the exit request.

 ## Decision
 
-`headless-runner` observes the exact Session it creates after startup quiescence and before submitting the task. Once the owned interval opens with `turn/start`, each non-empty `assistant/chunk.reasoning-delta` is written immediately to stderr. A contiguous reasoning phase starts with `dsh: reasoning:` on its own line; deltas retain provider order without token-boundary decoration. The first later non-reasoning chunk, a new turn, or listener disposal terminates the phase with one newline when the provider supplied none.
+`headless-runner` observes the exact Session it creates after startup quiescence and before submitting the task. Once the owned interval opens with `turn/start`, each non-empty `assistant/chunk.reasoning-delta` is written immediately to stderr. A contiguous reasoning phase starts with `dsh: reasoning:` on its own line; deltas retain provider order without token-boundary decoration. Reasoning block boundaries and usage metadata keep that phase open; a later non-reasoning block or output delta, stream finish, new turn, or listener disposal terminates it with one newline when the provider supplied none.
 
 This output is a transient projection of the existing durable Session event stream. The runner still derives final text and exit status from the flushed log rather than from progress-presentation state. The LLM adapter, agent loop, Session event types, persistence format, and SDK projections do not change.

 该输出是既有持久化会话事件流的瞬时投影。runner 仍从 flush 后的日志而不是进度呈现状态推导最终文本与退出状态。LLM（大语言模型）适配器、agent loop（智能体循环）、Session 事件类型、持久化格式与 SDK 投影均不改变。

 - **One submitted task only** — the runner has no interactive follow-up surface; it waits through any work the Agent completes before returning to idle and prints the last non-empty assistant message in that interval.
 - **No pre-token heartbeat** — stderr remains silent until the provider emits a non-empty reasoning delta; a provider that delays its first streamed token exposes no earlier progress signal.
+- **Reasoning enters stderr logs** — redirection and supervisors may retain substantially more and potentially sensitive model output; route stderr to a controlled sink when that content must not be collected.

 ## Verification
 
-The package test holds the Agent active after a reasoning delta and observes stderr before idle, then pins newline ownership for provider-terminated and unterminated phases plus terminal errors. The keyless product snapshot drives the shipped headless profile through a reasoning-plus-tool round and pins both stderr and the persisted Session. Built-bin acceptance sends `reasoning_content` through the native DeepSeek SSE adapter and requires reasoning on stderr while stdout remains the final answer.
+The package test holds the Agent active after a reasoning delta and observes stderr before idle, then pins newline ownership for provider-terminated and unterminated phases plus terminal errors. The owner-local product expectation drives the shipped headless profile through a reasoning-plus-tool round and pins both stderr and the persisted Session. Recorded-session replay reconstructs expected stderr from scalar and packed chunk rows, closes sections on packed text and tool-call output, and uses the raw run log before fixture path tokenization in record modes. Built-bin acceptance sends `reasoning_content` through the native DeepSeek SSE adapter and requires reasoning on stderr while stdout remains the final answer.

 ## 验证
 
-包测试在推理分片后保持 Agent 活跃，并在 idle 前观察 stderr；测试同时固定由提供方终止和未终止的推理段换行归属，以及终止态错误。无密钥产品快照通过包含推理与工具调用的轮次驱动随附 headless profile，并固定 stderr 与持久化 Session。构建后二进制验收通过原生 DeepSeek SSE（Server-Sent Events）适配器发送 `reasoning_content`，要求推理出现在 stderr，同时 stdout 仍只包含最终答案。

+# Agent Note: Exact Web per-Turn token usage
+
+Status: implemented
+
+English | [中文](2026-08-24-web-per-turn-token-usage.zh.md)
+
+## Problem
+
+Web Chat exposes cumulative session token usage near the composer, but that value cannot explain the cost of one completed Turn. A paged history window may begin inside a Turn, retries may consume several model calls, streaming and final events may repeat one attempt's usage, and optional cache fields do not prove an exact total. Displaying a partial subtotal as Turn usage would make recorded provider facts look more complete than they are.
+
+## Decision
+
+The shared `TokenUsage` value carries optional `totalTokens` for one model call. Adapters publish it only from an exact provider total or authoritative aggregate prompt and output counters. DeepSeek checks its prompt-plus-completion aggregate against any wire total, and pi-ai preserves its provided total.
+
+Token-meter owns a browser-safe pure Turn-local fold over durable session events, shared with its retry-aware cumulative usage projection. `step/start` and `llm/retry-started` open actual attempts; a final assistant message replaces the same attempt's streaming sample; terminal failures, retries, and step boundaries close attempts without double counting. Every started attempt must close with safe non-negative integer usage and an exact total. Optional cache, reasoning, and route aggregates appear only when every contributing attempt reports them, and reasoning remains a subset of output.
+
+Web Chat selects a Turn only when its loaded match window includes `turn/start`, passes that complete durable-event window to the token-meter fold, and renders the result. A complete, exact result appears through a local-state `DisclosureRow` above the existing actions; incomplete or contradictory evidence produces no row. Chat owns no token-accounting state machine.
+
+## Alternatives considered
+
+**Subtract neighboring cumulative session values.** Rejected because pagination, compaction, retry coverage, and projection completeness can make adjacent values incomparable; subtraction would infer data that no call reported.
+
+**Publish historical per-Turn values through a new client session projection.** Rejected because the loaded per-Turn view already has the durable attempt events it needs, while a history-growing projection would add transport, persistence, and versioning costs. Reusing token-meter's pure fold keeps one accounting owner without adding another wire value.
+
+**Show known buckets without an exact total.** Rejected because a lower-bound subtotal presented in a completed Turn footer is indistinguishable from a complete bill.
+
+## Consequences
+
+New provider records can expose exact per-Turn accounting without a new transport or persisted UI state. Older sessions and adapters without enough evidence simply omit the disclosure. Model routes disappear as a group when any billed attempt lacks attribution, while trustworthy token totals remain visible.
+
+Focused adapter, token-meter fold/projection, component, pagination, and assembled Web replay tests pin total preservation, retry-attempt separation, fail-closed validation, optional-field omission, interaction, and full-window publication. The cumulative projection and exact Turn fold now share token-meter ownership; the projection remains a whole-log bucket view, while the fold alone makes the stricter exactness and completeness claim required by the disclosure.

+# Agent Note: Web 单轮次精确 token 用量
+
+Status: implemented
+
+[English](2026-08-24-web-per-turn-token-usage.md) | 中文
+
+## Problem
+
+Web Chat 在编辑框附近显示会话累计 token 用量，但该值无法解释一个已完成轮次的消耗。分页历史窗口可能从轮次中间开始，重试可能消耗多次模型调用，流式事件与最终事件可能重复携带同一次 attempt 的用量，而可选 cache 字段也不能证明精确总量。将局部小计显示成轮次用量，会让已记录的提供方事实显得比实际更完整。
+
+## Decision
+
+共享 `TokenUsage` 值为一次模型调用携带可选的 `totalTokens`。适配器只从提供方精确总量，或权威的提示词与输出聚合计数发布该字段。DeepSeek 会将提示词加输出的聚合值与协议提供的总量核对，pi-ai 则保留其提供的总量。
+
+token-meter 拥有一份可安全用于浏览器的纯轮次局部 fold，并与其具备重试感知能力的累计用量投影共享记账所有权。`step/start` 与 `llm/retry-started` 打开真实 attempt；最终 assistant 消息替换同一 attempt 的流式样本；终止失败、重试与步骤边界关闭 attempt，且不会重复计数。每个已开始的 attempt 都必须以安全的非负整数用量和精确总量关闭。只有每个参与聚合的 attempt 都报告时，才会显示可选的 cache、推理与路由聚合值；推理仍是输出的子集。
+
+Web Chat 只选择已加载匹配窗口包含 `turn/start` 的 Turn，将该完整的持久事件窗口交给 token-meter fold，再渲染结果。完整且精确的结果通过现有 actions 上方、仅保留本地状态的 `DisclosureRow` 显示；证据不完整或矛盾时不显示该行。Chat 不拥有 token 记账状态机。
+
+## Alternatives considered
+
+**对相邻的会话累计值做减法。** 不采用，因为分页、压缩、重试覆盖范围与投影完整性可能让相邻值无法比较；减法会推断任何调用都未报告的数据。
+
+**通过新的客户端会话投影发布历史单轮次值。** 不采用，因为已加载的单轮次视图已经拥有所需的持久 attempt 事件，而随历史增长的投影会增加传输、持久化与版本成本。复用 token-meter 的纯 fold，可以在不新增 wire 值的前提下保持唯一记账所有方。
+
+**缺少精确总量时仍显示已知 bucket。** 不采用，因为在已完成轮次 footer 中展示的下界小计与完整账单无法区分。
+
+## Consequences
+
+新的提供方记录无需新增传输接口或持久化 UI 状态，即可显示精确的单轮次记账。证据不足的旧会话与适配器只会省略 disclosure。任一计费 attempt 缺少归属时，模型路由会整体消失，可信 token 总量仍可显示。
+
+定向的适配器、token-meter fold／投影、组件、分页与组装 Web 回放测试固定了总量保留、重试 attempt 分离、fail-closed 校验、可选字段省略、交互与完整窗口发布。累计投影与精确 Turn fold 现在同归 token-meter 所有；投影仍是完整日志的 bucket 视图，只有 fold 会作出 disclosure 所需的更严格精确性与完整性声明。

 - pi-ai tool-call arguments are parsed objects; the harness stores raw JSON strings. The adapter parses input and re-stringifies output.
 - pi-ai reports failures as in-stream error events; these map to `finish {kind:'error'|'aborted', failure}` chunks. Provider-specific error text distinguishes terminal `QUOTA` from transient `RATE_LIMIT`, while text and usage signals evaluated against the resolved model's context window normalize overflow to `CONTEXT_WINDOW_EXCEEDED`. A terminal `stop` whose message carries no content blocks maps to a `finish {kind:'error'}` with code `EMPTY_RESPONSE` (retried by default policy) instead of a successful empty message.

 - pi-ai's `off` thinking level crosses the Harness capability seam unchanged and becomes an omitted pi-ai common `reasoning` option at dispatch.
 - `GenerateOptions.stop` is rejected with `UNSUPPORTED_OPTION` because pi-ai's common streaming UI cannot guarantee it across providers.

 When the composition provides `ctx.sessionProjections`, token-meter registers three units through an optional child fiber.
 
-`tokenUsage` carries the complete durable log's `uncachedInputTokens`, `outputTokens`, `cacheReadTokens`, and `cacheWriteTokens`. Usage chunks are counted even when a request later fails; a final assistant-message usage for the same `(turn, step)` replaces that sample instead of double-counting it. Reasoning remains an output subdivision. The single last-sample slot relies on a session-log ordering property: once a later step reports usage, a legal log never reports usage for an earlier step again.
+`tokenUsage` carries the complete durable log's `uncachedInputTokens`, `outputTokens`, `cacheReadTokens`, and `cacheWriteTokens`. Usage chunks are counted even when a request later fails; a final assistant-message usage replaces the streaming sample from the same model attempt instead of double-counting it. A matching `llm/retry-started` boundary ends that replacement scope, so a retry with the same `(turn, step)` contributes a new billed attempt. Reasoning remains an output subdivision. The single last-sample slot relies on a session-log ordering property: once a later step reports usage, a legal log never reports usage for an earlier step again.
+
+Token-meter also owns the browser-safe pure fold from one complete Turn's durable events to exact attempt and Turn usage. `step/start` and `llm/retry-started` open real attempts; final message usage replaces that attempt's streaming sample; terminal failures, retries, and step boundaries close it. Missing lifecycle evidence, unsafe counts, or contradictory exact totals fail closed. Presentation consumers select a complete Turn window and render the result; they do not define a second accounting state machine.
 
 `contextPressure` carries optional `pressureTokens` — the newest provider-reported prompt size, summing uncached input plus cache reads and writes — optional `projectedTokens`, and optional `contextWindow` from the newest `request/context` record. Both figures stay absent until a provider reports usage; capacity stays absent for a route whose adapter advertises none. Output is excluded, so `pressureTokens` holds still while a turn streams and steps forward when the next request reports its usage.

 当组合提供 `ctx.sessionProjections` 时，token-meter 会通过一个可选子 fiber 注册三个单元。
 
-`tokenUsage` 携带完整持久日志中的 `uncachedInputTokens`、`outputTokens`、`cacheReadTokens` 和 `cacheWriteTokens`。即使请求随后失败，用量分片仍会计入；同一 `(turn, step)` 的最终 assistant 消息用量会替换该样本，而不是重复计数。推理仍是输出的一个细分项。只保留单个最新样本，依赖的是会话日志的一条顺序性质：一旦某个更晚的步骤报告了用量，合法日志就绝不会再为更早的步骤报告用量。
+`tokenUsage` 携带完整持久日志中的 `uncachedInputTokens`、`outputTokens`、`cacheReadTokens` 和 `cacheWriteTokens`。即使请求随后失败，用量分片仍会计入；最终 assistant 消息用量会替换同一次模型 attempt 的流式样本，而不是重复计数。匹配的 `llm/retry-started` 边界会结束该替换作用域，因此复用同一 `(turn, step)` 的重试会贡献一次新的计费 attempt。推理仍是输出的一个细分项。只保留单个最新样本，依赖的是会话日志的一条顺序性质：一旦某个更晚的步骤报告了用量，合法日志就绝不会再为更早的步骤报告用量。
+
+token-meter 还拥有一份可安全用于浏览器的纯 fold，将一个完整 Turn 的持久事件归并为精确的 attempt 与 Turn 用量。`step/start` 与 `llm/retry-started` 打开真实 attempt；最终消息用量替换该 attempt 的流式样本；终止失败、重试与步骤边界关闭它。缺少生命周期证据、计数不安全或精确总量矛盾时一律 fail-closed。展示消费方只选择完整 Turn 窗口并渲染结果，不再定义第二套记账状态机。
 
 `contextPressure` 携带可选的 `pressureTokens`（提供方报告的最新提示词规模，为未缓存输入加缓存读取与写入之和）、可选的 `projectedTokens`，以及来自最新一条 `request/context` 记录的可选 `contextWindow`。提供方报告用量前两个数字都保持缺失；路由适配器未公布容量时容量也保持缺失。输出不计入其中，因此轮次流式输出期间 `pressureTokens` 保持不动，等到下一个请求报告用量时才前进。
