+# Agent Note: Feature-owned tabs in Plugins settings
+
+Status: implemented
+
+English | [中文](2026-08-11-plugin-settings-tabs.zh.md)
+
+## Problem
+
+Plugin configuration and the read-only Loader inventory each registered a top-level `settings.section`. They described the same Plugins domain but occupied two navigation rows, split search and configuration into unrelated pages, and gave the Settings shell no principled way to present them together. Combining their components directly would instead make one feature plugin import and own the other feature's data lifecycle.
+
+## Decision
+
+`@deepseek-ai/dsh-client-ui-plugin-config` owns the single `settings.section` contribution with id `plugins`. It renders the shared title and compact tab chrome, declares the root-scoped list slot `settings.plugins.tab`, and projects that ledger's id, order, and locale-following label into its tabs. The slot's canonical type lives in `ui-settings`, so a tab contributor depends on the Settings domain contract rather than on another feature plugin.
+
+The section owner contributes a `configurable` tab that declares the existing nested `settings.plugin.item` list. Configuration cards keep their namespace bindings, draft state, validation, and writes unchanged. `@deepseek-ai/dsh-client-ui-plugins` contributes an `all` tab to `settings.plugins.tab`; its Host Loader observer, generated Remote namespace, DTO, and search semantics remain unchanged. Disabled inventory entries omit the redundant unmounted runtime state from summaries and details, while enabled entries continue to expose their Cordis phase.
+
+The first ordered tab is selected by default. A tab mounts only when first selected and then remains mounted but hidden while the Plugins section stays mounted. This delays the inventory RPC until the user opens **Plugin list** and preserves drafts, search text, disclosure state, and the fetched snapshot while switching tabs. Closing Settings unmounts the section, so reopening it obtains a fresh inventory snapshot when that tab is selected again.
+
+Both registrations use `ctx.slots.inject()`. If the section declarer unloads, the tab declaration and every contribution collapse with it; redeclaration lets each feature re-register without a static import or activation-order dependency.
+
+## Alternatives considered
+
+**Keep two Settings navigation rows and only rename them.** Rejected because the duplication is structural, not copy-related: both pages still represent the same Plugins domain and compete for navigation space.
+
+**Import the inventory component into `ui-plugin-config`.** Rejected because the configuration plugin would then own another plugin's Remote dependency and lifecycle. It would also turn an optional browser contribution into a package-level dependency.
+
+**Hard-code the two tab labels and components in the section owner.** Rejected because a third feature would require editing the owner, and HMR teardown could leave chrome for a contribution that no longer exists. The slot ledger already provides identity, ordering, localization, and cascade semantics.
+
+**Move Plugins aggregation into `ui-settings-general`.** Rejected because the Settings shell owns generic navigation and modal chrome, not feature content. Adding Plugins-specific tabs there would make every future Plugins view a shell change.
+
+## Consequences
+
+Settings has one Plugins navigation row, ordered before Agent Presets, with **Plugin configuration** and **Plugin list** tabs. Agent Presets remains an independent section because it edits per-session agent compositions rather than the live Host Loader tree.
+
+Feature ownership remains explicit: `ui-plugin-config` owns the Plugins page and editable cards, `ui-plugins` owns the read-only inventory view, and the Host/RPC path does not change. A new Plugins view can join by registering one `settings.plugins.tab` contribution.
+
+The aggregation depends on the section owner being composed: without `ui-plugin-config`, `ui-plugins` waits for a tab declaration and renders nothing. That is an intentional composition dependency carried by the slot registry rather than a static package import.

+# Agent Note: “插件”设置中的功能自有标签页
+
+Status: implemented
+
+[English](2026-08-11-plugin-settings-tabs.md) | 中文
+
+## 问题
+
+插件配置与只读 Loader 清单各自注册了一个顶层 `settings.section`。两者描述同一个“插件”领域，却占据两行导航，把搜索与配置拆成互不相关的页面，也没有给 Settings 外壳一个有原则的聚合方式。若直接合并两者的组件，则会让一个功能插件 import 并拥有另一个功能的数据生命周期。
+
+## 决策
+
+`@deepseek-ai/dsh-client-ui-plugin-config` 拥有唯一一个 id 为 `plugins` 的 `settings.section` 贡献。它渲染共享标题和紧凑标签栏，声明根级列表 slot `settings.plugins.tab`，并把该记录中的 id、order 与跟随语言的 label 投影成标签页。该 slot 的规范类型位于 `ui-settings`，因此标签页贡献方依赖设置领域约定，而不是依赖另一个功能插件。
+
+分区拥有方贡献 `configurable` 标签页，由它声明既有的嵌套 `settings.plugin.item` 列表。配置卡片原有的命名空间绑定、草稿状态、校验与写入均保持不变。`@deepseek-ai/dsh-client-ui-plugins` 向 `settings.plugins.tab` 贡献 `all` 标签页；它的 Host Loader 观察器、生成的 Remote 命名空间、DTO 与搜索语义保持不变。已停用的清单条目会在摘要和详情中省略重复的“未挂载”运行状态，已启用条目仍显示其 Cordis 阶段。
+
+默认选择顺序中的第一个标签页。某个标签页只有首次被选择时才挂载，之后在“插件”分区保持挂载期间只隐藏而不卸载。这样会把清单 RPC 延迟到用户打开**插件列表**时，并在切换标签页时保留草稿、搜索文本、折叠状态和已读取的快照。关闭 Settings 会卸载该分区，因此再次打开后，重新选择该标签页时会取得新的清单快照。
+
+两项注册都使用 `ctx.slots.inject()`。分区声明方卸载时，标签 slot 及其全部贡献随之折叠；重新声明后，每项功能都能重新注册，无需静态 import，也不依赖激活顺序。
+
+## 备选方案
+
+**保留两行 Settings 导航，只改名称。** 否决，因为重复是结构问题，而非文案问题：两个页面仍然代表同一个“插件”领域，并继续争夺导航空间。
+
+**把清单组件 import 进 `ui-plugin-config`。** 否决，因为配置插件会因此拥有另一个插件的 Remote 依赖与生命周期，也会把可选的浏览器贡献变成包级依赖。
+
+**在分区拥有方硬编码两个标签页的名称和组件。** 否决，因为第三项功能需要修改拥有方，HMR teardown 也可能留下已不存在贡献的界面框架。slot 记录已经提供标识、顺序、本地化与级联语义。
+
+**把“插件”聚合移入 `ui-settings-general`。** 否决，因为 Settings 外壳拥有通用导航与模态界面框架，而不拥有功能内容。把“插件”专属标签页放在那里，会让今后每一种“插件”视图都需要修改外壳。
+
+## 影响
+
+Settings 只有一行“插件”导航，排在“Agent 预设”之前，包含**插件配置**与**插件列表**两个标签页。“Agent 预设”仍是独立分区，因为它编辑每个会话的 agent 组装，而非实时 Host Loader 树。
+
+功能所有权保持明确：`ui-plugin-config` 拥有“插件”页面与可编辑卡片，`ui-plugins` 拥有只读清单视图，Host／RPC 路径不变。新的“插件”视图只需注册一个 `settings.plugins.tab` 贡献即可加入。
+
+该聚合依赖分区拥有方被组装：没有 `ui-plugin-config` 时，`ui-plugins` 会等待标签 slot 的声明且不渲染任何内容。这是通过 slot 注册表承载的有意组合依赖，而不是静态包 import。

+# Agent Note: Full-session stats-strip figures through a sessionStats projection
+
+Status: implemented
+
+English | [中文](2026-08-12-full-session-turn-step-counts.zh.md)
+
+## Problem
+
+The web chat stats strip folded `StatsLine`'s loaded conversation window (`deriveStats` over `chat.legacy.nodes`) for every non-token figure: the "N turns · M steps" counter, the LLM and tool wall times, and the TTFT/throughput averages. History is paged 50 messages at a time, so each 加载更早 (Load earlier) click grew the window and every figure with it — 7 turns · 44 steps became 10 turns · 89 steps after one page, and the LLM duration climbed the same way. The product expectation is whole-session figures independent of how much history a client has loaded. Token accounting in the same strip already had the correct architecture: the durable `tokenUsage` projection.
+
+## Decision
+
+A new function plugin `@deepseek-ai/dsh-session-stats` registers a `sessionStats` projection unit on `ctx.sessionProjections`, mounted as a web-app bundle row. The value carries the strip's whole non-token figure set — `{ turns, steps, llmMs, toolMs, ttftMs, ttftSteps, decodeMs, decodeTokens }`, field names mirroring the window fold so the two swap wholesale. `steps` counts `step/end` events and `turns` counts distinct turns carrying at least one (turn numbers are monotonic, so one `lastTurn` slot suffices); `llmMs` sums `step/start` → `assistant/message`; TTFT records the first non-empty delta chunk per step (surviving in-step `llm/retry`, the window `resetForRetry` parity); decode spans first token → assembled message on usage-reporting steps; `toolMs` pairs `tool/call` → `tool/result` by callId with unresolved calls dropped at `turn/end`. The first-token predicate `isTokenDelta` moved to `@deepseek-ai/dsh-llm/message` (beside the `StreamChunk` type it discriminates) so the host fold and the client timing index share one implementation; client-runtime re-exports it. Delivery is entirely the existing projection seam — history tail-page block, `session/projection` push frames, list rows — with zero changes to apiproxy, wire schemas, or the client runtime. `StatsLine` reads `useProjection('sessionStats')` and falls back to the window fold when the key is undefined (an assembly without the unit). The client connection fixture mirrors the fold as `sessionStatsOf` under its existing every-composed-key discipline.
+
+`step/end` — not `assistant/message` — is the counted event, for two correctness reasons found while reviewing the obvious message-counting design:
+
+1. A max-tokens step appends an empty-content `assistant/message` that exists only to host usage and never reaches the surface; counting messages would count a step the transcript does not show.
+2. A cancelled step aborts before its message assembles (no `assistant/message` at all), yet the client synthesizes a visible interrupted assistant node; counting messages would silently drop common cancelled steps.
+
+`step/end` is appended exactly once per entered step, in the loop's `finally`, so completed, failed, cancelled, and max-tokens steps all land one — and the counter advances at step settlement, the same moment the window fold advanced, so live behavior does not shift.
+
+## Alternatives considered
+
+**Count `assistant/message` events.** Rejected for the two correctness defects above (overcounts usage-host messages, undercounts cancelled steps).
+
+**Count `step/start` events.** Equivalent coverage (it precedes every `step/end`), but the counter would advance when a step begins instead of when it settles — a visible live-behavior change with no benefit; `step/end`'s `finally` placement gives the same completeness.
+
+**Register the unit in `core/agent-loop` (the event producer).** The loop is the product spine; a UI read model there adds a session-projection dependency to every assembly, against "plugins, not loop changes" and "keep opt-ins out of shipped defaults".
+
+**Register the unit in `token-meter` (an existing fold over the same events).** Turn/step counting is not token measurement; every projection key lives in the package owning its domain.
+
+**Fold the full log client-side.** The client holds only the paged window by design; the projection RFC's no-client-folding rule exists exactly so figures survive paging, compaction, and cold reads.
+
+**Keep wall times, TTFT, and throughput window-scoped, reading them as "what is on screen".** Rejected: the same paging complaint applies to the LLM duration, and a strip mixing whole-log counts with window-scoped times reads as one inconsistent figure set. The projection carries the whole set, with the window fold demoted to the no-unit fallback.
+
+## Consequences
+
+The strip shows whole-log figures from the first tail page; paging leaves every group fixed. Defined edge differences from the old window semantics are documented in the package README: a step that produced no visible output (failed before content) still counts, a step interrupted by a crash counts once recovery closes it with a synthetic `step/end` on reload (`interruptedTurnClosers`), a cancelled step is counted but contributes no wall time (no message assembled), and a max-tokens usage-host message contributes model time the surface does not show. Every web tail page and list row carries one more small key, and the unit's internal state changes on step boundaries and first-token chunks, so the change feed emits a few value-identical frames per step; TUI and headless assemblies serve no `sessionStats` key and any consumer falls back to window folding. Two e2e probes that had parsed the strip as a loaded-window measure (`chat-scroll-contract`, `complex-history.perf`) now count mounted flow rows / turn-tail footers instead. The `stats-paged-history` web scenario seeds a 28-turn log cold and pins that the whole strip reads full totals on a partial tail page and does not move across Load earlier.

+# Agent Note: 通过 sessionStats 投影提供全会话统计条数字
+
+Status: implemented
+
+[English](2026-08-12-full-session-turn-step-counts.md) | 中文
+
+## 问题
+
+Web 聊天统计条的每个非 token 数字都折算自 `StatsLine` 已加载的会话窗口（`deriveStats` 遍历 `chat.legacy.nodes`）：「N 轮 · M 步」计数、LLM 与工具墙钟时间、TTFT／吞吐平均值。历史按每页 50 条消息分页，因此每点一次「加载更早」窗口变大、所有数字随之增长——7 轮 · 44 步在翻一页后变成 10 轮 · 89 步，LLM 时长同样攀升。产品预期是与客户端加载了多少历史无关的全会话数字。同一统计条里的 token 账目早已采用正确架构：持久的 `tokenUsage` 投影。
+
+## 决定
+
+新的函数插件 `@deepseek-ai/dsh-session-stats` 在 `ctx.sessionProjections` 上注册 `sessionStats` 投影单元，作为 web-app bundle 行挂载。值携带统计条完整的非 token 数字集——`{ turns, steps, llmMs, toolMs, ttftMs, ttftSteps, decodeMs, decodeTokens }`，字段名与窗口折叠一一对应以便整体互换。`steps` 统计 `step/end` 事件，`turns` 统计含至少一条该事件的不同 turn（turn 号单调递增，一个 `lastTurn` 槽即可）；`llmMs` 累加 `step/start` → `assistant/message`；TTFT 记录每步首个非空 delta chunk（在步内 `llm/retry` 后保留，与窗口 `resetForRetry` 对齐）；解码时长覆盖首 token → 已组装消息、仅统计上报 usage 的步；`toolMs` 按 callId 配对 `tool/call` → `tool/result`，未解决的调用在 `turn/end` 时丢弃。首 token 谓词 `isTokenDelta` 移入 `@deepseek-ai/dsh-llm/message`（与其判别的 `StreamChunk` 类型同处），Host 折叠与客户端计时索引共用同一实现；client-runtime 转发导出。投递完全复用现有投影缝——history 尾页块、`session/projection` 推送帧、列表行——apiproxy、wire schema 与客户端运行时零改动。`StatsLine` 读取 `useProjection('sessionStats')`，键为 undefined（未组合该单元的装配）时整体回退到窗口折叠。客户端 connection fixture 按其「镜像每个已组合键」的既有纪律以 `sessionStatsOf` 平行实现该折叠。
+
+计数事件选 `step/end` 而非 `assistant/message`，源于评审直觉方案（按消息计数）时发现的两个正确性问题：
+
+1. max-tokens 步会追加一条仅为承载 usage 而存在的空内容 `assistant/message`，它从不进入 surface；按消息计数会把 transcript 上看不到的步计进去。
+2. 被取消的步在消息组装前就中止（完全没有 `assistant/message`），但客户端会合成可见的 interrupted assistant 节点；按消息计数会悄悄丢掉常见的取消步。
+
+`step/end` 对每个进入的步在循环的 `finally` 中恰好追加一次，因此完成、失败、取消、max-tokens 的步都恰好落一条——且计数在步结算时推进，与窗口折算推进的时机相同，直播期行为不发生变化。
+
+## 备选方案
+
+**统计 `assistant/message` 事件。** 因上述两个正确性缺陷否决（多计 usage 宿主消息、少计被取消的步）。
+
+**统计 `step/start` 事件。** 覆盖等价（它先于每条 `step/end`），但计数会在步开始而非结算时推进——一个没有收益的可见直播期行为变化；`step/end` 的 `finally` 位置给出同等完整性。
+
+**把单元注册进 `core/agent-loop`（事件生产方）。** 循环是产品主干；把 UI 读模型放进去会给每个装配加上 session-projection 依赖，违反「用插件而非改循环」与「默认组合不带可选项」。
+
+**把单元注册进 `token-meter`（折叠同批事件的现有单元）。** 轮/步计数不是 token 度量；每个投影键都住在拥有其领域的包里。
+
+**在客户端折叠全量日志。** 客户端按设计只持有分页窗口；投影 RFC 的「不在客户端折叠」规则正是为了让数字在分页、压缩与冷读之间存活。
+
+**墙钟时间、TTFT 与吞吐保持窗口口径，解读为「屏幕上有什么」。** 否决：同样的分页问题一样落在 LLM 时长上，且全量计数与窗口时间混在一条统计条里读起来是一套自相矛盾的数字。投影携带完整集合，窗口折叠降级为无单元时的回退。
+
+## 后果
+
+统计条从第一个尾页起就显示全日志数字；翻页不再改变任何分组。与旧窗口语义的已定义边缘差异记录在包 README 中：未产生可见输出的步（在内容之前失败）仍计入；被崩溃打断的步在重新加载、恢复为其补写合成 `step/end` 后计入（`interruptedTurnClosers`）；被取消的步计数但不计时（没有组装出消息）；max-tokens 的 usage 宿主消息贡献 surface 上看不到的模型时间。每个 web 尾页与列表行多携带一个小键，且单元内部状态在步边界与首 token chunk 处变化，变更流每步会多发几帧值相同的推送；TUI 与 headless 装配不提供 `sessionStats` 键，其消费者回退窗口折叠。两个曾把统计条当作已加载窗口探针解析的 e2e（`chat-scroll-contract`、`complex-history.perf`）改为统计已挂载的消息流行／turn-tail 页脚。`stats-paged-history` web 场景冷种一份 28 轮日志，钉住整条统计条在不完整尾页上即读出全量数字、且「加载更早」前后不变。

 Both feeds use `DSH_TELEMETRY_MODE` as their positive consent setting. Unset and empty values resolve to `DISABLED`. `@deepseek-ai/dsh-session-telemetry-otel` also resolves an omitted `mode` to `DISABLED`, which constructs no OTel provider, processor, or exporter and leaves feedback in the local session log. The shared dsh base keeps the backend row mounted so disabled feedback can still explain that nothing was shared. A deployment opts into Session Log sharing through `FULL` or `FEEDBACK_ONLY`; only `FULL` also permits dsh-sdk launcher reporting. Any non-empty `DSH_TELEMETRY_DISABLED` remains an authoritative pre-load hard opt-out.

+Three host-plane plugins register their own settings namespace, and one browser-side Plugins section aggregates feature-owned tabs. Its configurable tab renders whatever editable settings the deployment exposes.
 
 **Layering, unchanged.** A section resolves as schema defaults → the plugin's composition entry → the user layer. Each plugin passes its `cordis.yml` entry as the `base` and reads its config through a source thunk, so a stored change reaches the next use and a detaching settings provider leaves the composition entry running. Constraints the schema cannot express — positive and finite, the timer bound on `graceMs`, the parallel cap being a positive integer — become the section validator, so a bad value is refused at the write instead of at the next command.

 **Exposure stays a Host allowlist.** The three namespaces join `WEB_SETTINGS_NAMESPACES`; registration alone still never crosses the transport, and a namespace absent from that list answers `settings-not-exposed` exactly as an unregistered one does.
 
-**The section knows no namespace.** `dsh-client-ui-plugin-config` declares a `settings.plugin.item` slot and renders the cards registered into it, so a plugin that ships a browser half owns its card and its controls. Each card binds its namespace through the client settings scope, which gained the two things a form needs: the raw `user` layer, whose key PRESENCE is what marks a field overridden, and `unset`, which clears one field back to the composition layer. A card renders nothing while its namespace is unavailable, so a deployment that does not compose the owning plugin shows no trace of it.
+**The configurable tab knows no namespace.** `dsh-client-ui-plugin-config` owns the Plugins section, contributes its `configurable` page through `settings.plugins.tab`, and declares a nested `settings.plugin.item` slot there.

 **A card stages its edits and writes them on save.** Controls hold no draft of their own: the card's form owns the staged text, every control renders it, and only **Save** turns it into document mutations. A settings write is durable and revision-fenced, so a control that committed as it settled spent a revision on a value the user had not decided to store and could not preview; the reset stages the composed default the same way. Because the Host's validators own the constraints no schema can express, the form reads the section back after writing and reports a save that did not land instead of predicting the outcome, keeping those drafts for the user to correct. The credential control is staged with the rest even though it writes through the credentials domain, so one save covers everything the card shows.

 Each of the three required Linux worker jobs, the independent native Windows job, and the `all checks passed` verdict job — which would otherwise stay queued on the failed pool even after every worker passed — resolves its runner pool through the `DSH_CI_FAILOVER` repository variable. Unset (normal), they run on the hosted enterprise pools. Set to `selfhosted` by any repository writer, all five retarget onto the in-house self-hosted pools: the Linux jobs and verdict onto the `vm-backup` pool, coverage and snapshot concurrency drop to shared-VM bounds, and the hosted-path pnpm cache restores are skipped; the native Windows job onto the `dsh-win-ci` pool. The switch is writer-manageable repository state, not a merge, so it works while every check is red. The in-house pools' readiness is continuously re-proven by the `serial / linux (self-hosted standby)` and `serial / windows (self-hosted standby)` lanes, which run the complete unsharded aggregates on every master push.
 
+`ci.yml` exempts exactly one event from `cancel-in-progress` (`${{ github.event_name != 'push' }}`), so one master push does not cancel the drill still running from the previous one. Each drill runs its complete unsharded aggregate with one gate worker, which takes longer than the interval between master merges; under unconditional cancellation a drill is superseded before reaching a verdict and the lane yields no readiness evidence for a responder to check.
+
+The exemption is narrower than "a drill always finishes", in two ways. GitHub keeps a single pending entry per group, so a newer pending run displaces an older one and intermediate push runs still end as `cancelled` during busy periods. And the expression is evaluated against the *newly triggered* run, so a run whose own event is not `push` — a benchmark dispatched on master, sharing the group `CI-<ref>` — evaluates to `true` and does cancel a drill that is mid-flight. That is a rare manual action and the next master push restores the evidence, so it does not warrant further mechanism. What the carve-out buys is that the lane periodically reaches a verdict at all, which is what makes it usable as evidence.
+
+The decision belongs at workflow level because cancellation applies to the whole superseded run: a job-level `concurrency` group does not exempt its job. The negated form is load-bearing rather than cosmetic: naming `pull_request` alone would also stop cancelling `workflow_dispatch`, and each runner benchmark fans out to twelve larger runners for up to fifteen minutes inside this same group on master, so a re-dispatch would queue ahead of a drill instead of replacing a stale measurement. What bounds the cost is that a master push carries only `wine-apt-cache` and these two drills; every other job is pull-request-gated, `workflow_dispatch`-gated, or `if: false`, and `scripts/ci-workflow.spec.ts` pins that set — classifying by exact condition, since a negated event test mentions the event it excludes — so a new push-reachable job cannot quietly start accumulating uncancelled runs.

 ### What the in-house pool is
 
 `vm-backup`: one 64-core VM, six always-on systemd-managed runner instances. Its image must preinstall Playwright Chromium's Linux system packages; CI downloads the lockfile-selected browser but never runs `apt` on this persistent shared host. Check the latest `serial / linux (self-hosted standby)` run before switching: its aggregate includes browser replay, so a green standby verifies both ordinary capacity and this browser prerequisite.

+`ci.yml` 只豁免一个事件不做取消（`${{ github.event_name != 'push' }}`），因此一次 master 推送不会取消上一次推送留下的、仍在运行的演练。每次演练以单门禁工作进程执行完整的未分片聚合流程，耗时长于 master 合并的间隔；在无条件取消下，演练会在得出结论前被后续运行取代，该通道无法产出供响应者查看的就绪证据。
+
+这项豁免比「演练总能跑完」要窄，有两点限制。其一，GitHub 每个组只保留一个待运行条目，更新的待运行条目会顶掉更早的，繁忙时段中间的推送运行仍会以 `cancelled` 结束。其二，该表达式是针对**新触发的运行**求值的，因此自身事件不是 `push` 的运行——例如在 master 上派发的基准测试，与演练共用 `CI-<ref>` 组——求值为 `true`，会取消正在运行中的演练。这属于罕见的手动操作，且下一次 master 推送即可恢复证据，因此不值得为它再加机制。这项豁免换来的是该通道**周期性**地得出结论，而这正是它能作为证据的前提。
+
+这个决定必须放在工作流级：取消作用于被取代的整个运行，作业级 `concurrency` 组并不能豁免其所属作业。采用否定式写法而非仅指名 `pull_request`，是有实质作用的：后者会连 `workflow_dispatch` 一起停止取消，而每次运行器基准测试会在 master 上的同一并发组内同时占用 12 台大规格运行器、最长 15 分钟，届时重复派发会排在演练之前，而不是替换掉已过时的测量。成本之所以可控，是因为一次 master 推送只承载 `wine-apt-cache` 和这两条演练；其余作业都受拉取请求门控、`workflow_dispatch` 门控或 `if: false`，并且 `scripts/ci-workflow.spec.ts` 会锁定这个集合——按条件精确匹配，因为否定式事件判断会包含它所排除的事件名——使新的推送可达作业无法悄悄开始累积未取消的运行。
+
 ### 自有池是什么
 
 `vm-backup`：一台 64 核虚拟机，6 个常驻 systemd 管理的运行器实例。其镜像必须预装 Playwright Chromium 的 Linux 系统软件包；CI 会下载锁文件选定的浏览器，但绝不在这台持久化共享主机上运行 `apt`。切换前先看 `serial / linux (self-hosted standby)` 最近一次运行：其聚合流程包含浏览器回放，因此绿色热备同时验证常规容量和这项浏览器先决条件。

A card shows the plugin's name and what it governs; expanding it in place reveals hand-written controls bound to that plugin's settings namespace, each field marking whether the user overrode it and offering a reset back to the value the deployment composed.
+The **Plugins** settings section and its **Plugin configuration** tab. The section owns the heading and compact tab chrome; feature plugins contribute pages through `settings.plugins.tab`.

A card shows the plugin's name and what it governs; expanding it in place reveals hand-written controls bound to that plugin's settings namespace, each field marking whether the user overrode it and offering a reset back to the value the deployment composed.
 
 ## What appears here
 
-The section reads which settings namespaces the Host serves and dispatches one slot key per namespace, so what renders is the intersection of two ledgers: the namespaces a live Host plugin registered, and the cards registered under those keys. A served namespace no card claims renders nothing — another surface owns it, or this deployment ships no browser half for it — and a card whose namespace this deployment does not serve is never dispatched, so an uncomposed plugin leaves no trace and does not hold the section back from its empty line. Cards appear in the order they registered, which is stable for the cards one package installs together and not stable across plugins: apply order between packages is unconstrained. The empty line waits for the Host's first answer, so an unanswered read never reads as "this deployment configures no plugin".

Cards appear in the order they registered, which is stable for the cards one package installs together and not stable across plugins: apply order between packages is unconstrained.
 
 The cards this package ships cover the shell executor (`bash`), the agent loop's tool-call parallelism (`agent-loop`), and the DeepSeek search provider (`web-search-deepseek`).
 
 ## Extension point
 
-The section declares `settings.plugin.item`, a root keyed slot whose key is the settings namespace a card edits. A plugin that ships a browser half registers its own card under its own namespace and owns every part of it — chrome, controls, and copy; this package supplies no form it was not given and never learns what a namespace means. Keying on the namespace is what lets a plugin distributed outside this repository appear here: it registers the namespace on the Host and the card in the browser, and the section pairs the two.
+The section declares `settings.plugins.tab`, a root list slot whose labels become ordered tabs. It keeps a tab mounted after its first selection, so local drafts and read-only snapshots survive tab switches.

 - **Only host-plane plugins appear** — a plugin an agent preset mounts carries its configuration inline in that preset's `agent.cordis.yml` and cannot register a settings namespace at all (a second session mounting the same preset would fail on a duplicate registration), so this section lists nothing for it. Editing those values remains the preset editor's job.
 - **A card still needs a browser bundle** — the browser half must be a `dsh.client` package built in the client module system's lazy-CJS factory format, and the `clientBundle` preset that emits it lives in `packages/client/tsdown.client.ts` rather than a published package, so a plugin outside this repository has to reproduce that build itself. The bundle-purity gate also forbids importing this package's card chrome or form model as values, so such a card owns its own staging and revision fencing.

The shell's own contract types live beside the shell for the same reason.
 
 The plugin injects nothing and waits for nothing: `ctx.settingsScope.bind(spec)` resolves the wire face through the CALLER's context at call time, so the bound scope's disposer belongs to the calling fiber, and the caller injects `connection` for the transport and `remote` for the invalidation. Listeners exist before the first background read starts, so a row's activation never blocks on the settings transport. A bound scope reloads on the forwarded `settings/document-updated` event for its own namespace and on `connection/reset`. Writes carry one field path and the last known namespace revision as `expectedRevision`; a rejected or failed write re-reads unless a newer write already superseded it, and a stale read never publishes over a newer one. Without a `decode` in the spec, a section that is not a plain object, fails its rehydrated schema, or carries a schema envelope this client cannot rehydrate publishes no value at all, so a row renders its own absent state instead of a half-decoded one.

 该插件不注入任何服务、也不等待任何服务：`ctx.settingsScope.bind(spec)` 在调用时经**调用方**的 context 解析线路面，因此绑定所得 scope 的 disposer 归调用方 fiber 所有，而由调用方注入 `connection` 取得传输层、注入 `remote` 取得失效通知。监听器在首次后台读取启动之前就已存在，因此某一行的激活绝不会阻塞在设置传输层上。已绑定的 scope 会在收到属于自己命名空间的转发 `settings/document-updated` 事件时、以及在 `connection/reset` 时重新读取。写入携带单一字段路径以及最近已知的命名空间 revision 作为 `expectedRevision`；被拒绝或失败的写入会重新读取，除非已有更新的写入取代了它，而过期的读取绝不会覆盖发布更新的结果。若 spec 未提供 `decode`，则分区不是普通对象、未通过其重建后的 schema 校验、或携带本客户端无法重建的 schema 信封时，一律不发布任何值，于是行渲染自己的缺失状态，而不是一份半解码的值。
