Committed mutations also drive the [Node-compatible watcher and confinement implementation](2026-08-23-webworker-vfs-watch-and-landlock.md). Boot diagnostics remain visible because cordis logger verbosity counts UP: `startWorkerHost` installs a console exporter with `levels: { default: 2 }` before any entry mounts, while an exporter with no declared level drops every warning.

 **The preview is the served page plus one tag.** One Vite build emits `dist/index.html` and `dist/preview.html` sharing every chunk; the only difference is a prepended bootstrap entry whose module connects the worker host. Startup then converges on one protocol: whichever side applies the injection table settles the `__DSH_BOOT_READY__` deferred — the served renderer resolves it in a tail script after the rendered rows, the worker bootstrap installs it before its first await and settles it after the last row — and the client entry awaits it before reading any injected state, so the chain from the stock entry onward is the served chain verbatim. Plugin combo scripts and maps travel through the tunnel; the page-side loader embeds each tunnel-only map as a Base64 data URL before executing its script Blob, preserving indexed-map component names in DevTools without another object-URL lifetime. The build uses a relative base so the output mounts under any static directory; the served form anchors deep SPA-fallback paths by rendering `<base href="/">` at serve time, keeping the on-disk pages byte-shared.

 - The transform corpus imports every built bundle through Node before comparing its lowered exports. Its pinned exemptions name the actual non-importable bundle and fail when one becomes importable: after Win32 process primitives became the Koffi type owner, `win32-process` carries the duplicate-type exemption and `sandbox-windows-acl` does not.
 - The served `<base href="/">` anchor exists because relative asset URLs would resolve under the request directory on SPA-fallback paths; remove it only together with the relative build base.
 - The image ships as a deterministically gzip-compressed tar (`vfs-image.tar.gz`; MTIME 0, OS byte 0xff): static hosts do not compress binary content types (type allowlists, CDN size caps), so the compression rides the artifact, and the worker inflates the fetch body through the browser's native `DecompressionStream` while it downloads.

+# Agent Note: Persistence compression latency and SQLite page size
+
+Status: implemented
+
+English | [中文](2026-08-25-persistence-latency-and-page-size.zh.md)
+
+## Problem
+
+The physical persistence optimizations need to reduce retained storage without moving disproportionate work into full writes, reads, or session forks. The original 105-session corpus showed that JSONL level-19 compression made full writes and forks more than twice as slow. The earlier SQLite page-size experiment predated shared-dictionary row compression and showed negligible savings, so it did not establish the best page size for the current row distribution.
+
+The decision needs evidence from more varied sessions, including long event streams and payloads outside the original corpus. The expanded corpus contains 501 real sessions, 16,153,332 logical events, and 2,002,145,570 bytes of serialized event data.
+
+## Decision
+
+### Storage encoding stays physical and independently decodable
+
+JSONL stores strictly increasing `sourceEventSeqs` as mixed scalar values and inclusive ranges; other orders remain verbatim. SQLite stores the same arrays as tagged zigzag-delta or `(start, count)` varints, choosing the smaller encoding. Both readers restore the original `number[]` before exposing an event.
+
+SQLite uses an internal integer `sessions.id` and keeps the public session id once in `sessions.session_key`, so event rows and their primary key do not repeat a text identifier. Each `events.data` value remains independently decodable: the writer tries level-3 Zstandard with the packaged 64 KiB raw-content dictionary and retains SQLite text when compression is not smaller. The dictionary bytes are part of schema 19 and a test pins their SHA-256 digest; replacing them requires another schema-version bump.
+
+### JSONL uses the standard Zstandard level
+
+The JSONL writer keeps one checksummed Zstandard frame per durable append batch but uses the compressor's standard level. Lossless `sourceEventSeqs` range encoding remains active. Frames stay independently decodable for suffix reads and torn-tail recovery; only the expensive level-19 search is removed.
+
+### New SQLite databases use 64 KiB pages
+
+The SQLite provider sets `page_size=65536` before initializing a pristine schema-19 database. An established schema-19 database retains its current page size because SQLite ignores the pragma after allocation.
+
+The page size is part of schema 19's fixed physical layout and is applied through the package's closed SQL resources like the other fixed SQLite pragmas.
+
+### Expanded benchmark
+
+Each candidate was rebuilt five times from the same 501-session corpus with 512-event append batches. Their order rotates between rounds so every candidate occupies each run position once. Each build runs three complete and suffix-read sweeps. For each displayed metric, the highest and lowest build are discarded and the remaining three values are averaged. Complete and suffix read times cover one sweep over all sessions, and fork time covers all 501 sessions.
+
+| Backend | Stored size | Full write | Full read | Suffix read | Fork |
+| --- | ---: | ---: | ---: | ---: | ---: |
+| JSONL `master` | 172.43 MB | 200.902 s | 8.033 s | 24.479 s | 72.670 s |
+| JSONL with provenance ranges | 148.15 MB (-14.1%) | 197.281 s (-1.8%) | 7.799 s (-2.9%) | 24.582 s (+0.4%) | 72.308 s (-0.5%) |
+| JSONL with provenance ranges and level 19 | 130.22 MB (-24.5%) | 329.442 s (+64.0%) | 7.764 s (-3.3%) | 24.454 s (-0.1%) | 166.177 s (+128.7%) |
+| SQLite `master` (schema 17) | 438.31 MB | 69.632 s | 8.211 s | 0.546 s | 64.290 s |
+| SQLite with all physical optimizations and 64 KiB pages | 233.18 MB (-46.8%) | 87.656 s (+25.9%) | 9.155 s (+11.5%) | 0.575 s (+5.3%) | 79.417 s (+23.5%) |
+
+Relative to standard-level frames with provenance ranges, level 19 saves another 12.1% of the JSONL bytes but increases full-write time by 67.0% and fork time by 129.8%. Its complete and suffix reads change by -0.4% and -0.5%. The extra search therefore benefits retained size without improving the latency-sensitive operations enough to offset its repeated encoding cost.
+
+An otherwise identical SQLite build isolates the page-size effect: 4 KiB pages use 256.97 MB and 64 KiB pages use 233.18 MB (-9.26%). The `events` table's unused page bytes fall from 30.25 MB to 6.95 MB, while the index changes from 5.92 MB to 6.03 MB. In the paired run, full write, full read, and suffix read change by -0.5%, -0.4%, and -3.8%; fork changes by -14.8%. The space gain therefore comes from better large-row page utilization rather than a smaller index or omitted data, without a measured latency regression.
+
+## Alternatives considered
+
+**Keep JSONL level 19.** Rejected. On the expanded corpus it saves another 12.1% relative to default-level frames but increases full-write time by 67.0% and fork time by 129.8%, while complete and suffix reads differ by less than 1%. Default-level frames plus provenance ranges retain a 14.1% size reduction relative to master without a material latency regression.
+
+**Compress one whole JSONL log as a single frame.** Rejected. It improves cross-batch compression but makes suffix reads decompress from the start and removes batch-local torn-tail recovery.
+
+**Keep 4 KiB SQLite pages.** Rejected for pristine databases. The current compressed-row distribution retains 9.26% more bytes because large compressed records leave more unusable space across 4 KiB B-tree pages. Existing databases keep their page size to avoid a historical rewrite.
+
+**Remove ROWID from `events`.** Rejected. The composite primary key becomes the table B-tree key and repeats through internal pages; the 105-session comparison produced a larger database than ordinary ROWID tables.
+
+**Deduplicate event content.** Rejected. Message restatements and tool arguments can be reconstructed only under assumptions that compaction, retries, and pruning may invalidate. Physical compression preserves every event without adding reconstruction semantics.
+
+**Use per-session SQLite files or DuckDB.** Rejected for the hot store. Per-session files lose cross-session queries, while DuckDB's OLAP write model fits cold batch analysis rather than durable append batches and low-latency suffix reads.
+
+## Consequences
+
+JSONL keeps the low-cost provenance optimization without the level-19 write and fork penalty. SQLite exchanges approximately 5–26% more time across the measured operations for a 46.8% retained-size reduction; its full write remains materially faster than JSONL, and its suffix read remains much faster. Its complete read and fork are slightly slower than default-level JSONL on this expanded corpus.
+
+New SQLite databases use 64 KiB WAL frames and cache pages. Small databases may reserve more bytes for sparsely populated schema and metadata pages, while the measured multi-session workload gains substantially better `events` page utilization. Schema 19 rejects every other schema version rather than migrating it.

+# Agent Note: 持久化压缩延迟与 SQLite page size
+
+Status: implemented
+
+[English](2026-08-25-persistence-latency-and-page-size.md) | 中文
+
+## 问题
+
+物理持久化优化需要减少保留存储，同时不能把不成比例的工作转移到完整写入、读取或会话 fork。原有的 105 会话语料显示，JSONL level-19 压缩会让完整写入与 fork 耗时增加一倍以上。此前的 SQLite page-size 实验早于共享字典行压缩，所得空间收益可以忽略，因此无法确定当前行分布的最佳 page size。
+
+该决策需要来自更多样会话的证据，包括长事件流与原语料之外的 payload。扩展后的语料包含 501 个真实会话、16,153,332 个逻辑事件与 2,002,145,570 字节序列化事件数据。
+
+## 决策
+
+### 存储编码保持为物理层行为并可独立解码
+
+JSONL 把严格递增的 `sourceEventSeqs` 存为标量值与闭区间的混合数组，其他顺序保持原样。SQLite 把同一数组存为带 tag 的 zigzag-delta 或 `(start, count)` varint，并选择更小的编码。两个读取方都会在暴露事件前还原原始 `number[]`。
+
+SQLite 使用内部整数 `sessions.id`，并只在 `sessions.session_key` 中保留一次公开会话 id，使事件行及其主键不再重复文本标识。每个 `events.data` 值仍可独立解码：写入方尝试用打包的 64 KiB raw-content 字典执行 level-3 Zstandard 压缩，结果不更小时保留 SQLite 文本。字典字节属于 schema 19，测试固定其 SHA-256 摘要；替换字典需要再次提升 schema 版本。
+
+### JSONL 使用 Zstandard 标准级别
+
+JSONL 写入方继续为每个持久 append 批次写入一个带 checksum 的 Zstandard frame，但使用压缩器的标准级别。无损 `sourceEventSeqs` 区间编码继续生效。各 frame 仍可独立解码，以支持后缀读取与撕裂尾部恢复；只移除昂贵的 level-19 搜索。
+
+### 新建 SQLite 数据库使用 64 KiB page
+
+SQLite 提供方在初始化全新 schema-19 数据库前设置 `page_size=65536`。SQLite 在 page 已分配后会忽略该 pragma，因此已有 schema-19 数据库保留其当前 page size。
+
+Page size 属于 schema 19 的固定物理布局，并与其他固定 SQLite pragma 一样通过包内封闭的 SQL 资源应用。
+
+### 扩展基准
+
+每个候选方案都从同一份 501 会话语料独立重建五次，每个 append 批次包含 512 个事件。各轮轮换执行顺序，使每个候选方案在每个运行位置各出现一次。每次重建执行三轮完整读取与后缀读取。下表中的每项指标都去掉最高与最低的一次重建，再平均其余三次。完整读取与后缀读取耗时覆盖对全部会话的一轮扫描，fork 耗时覆盖全部 501 个会话。
+
+| 后端 | 存储大小 | 完整写入 | 完整读取 | 后缀读取 | Fork |
+| --- | ---: | ---: | ---: | ---: | ---: |
+| JSONL `master` | 172.43 MB | 200.902 s | 8.033 s | 24.479 s | 72.670 s |
+| JSONL + 来源区间 | 148.15 MB (-14.1%) | 197.281 s (-1.8%) | 7.799 s (-2.9%) | 24.582 s (+0.4%) | 72.308 s (-0.5%) |
+| JSONL + 来源区间 + level 19 | 130.22 MB (-24.5%) | 329.442 s (+64.0%) | 7.764 s (-3.3%) | 24.454 s (-0.1%) | 166.177 s (+128.7%) |
+| SQLite `master`（schema 17） | 438.31 MB | 69.632 s | 8.211 s | 0.546 s | 64.290 s |
+| SQLite + 全部物理优化 + 64 KiB page | 233.18 MB (-46.8%) | 87.656 s (+25.9%) | 9.155 s (+11.5%) | 0.575 s (+5.3%) | 79.417 s (+23.5%) |
+
+相对使用来源区间的标准级别 frame，level 19 可再减少 12.1% 的 JSONL 字节，但会让完整写入增加 67.0%、fork 增加 129.8%；完整读取与后缀读取分别变化 -0.4% 与 -0.5%。因此，更深入的搜索只改善保留体积，无法通过延迟敏感操作的收益抵消反复付出的编码成本。
+
+其余条件相同的 SQLite 重建可单独观察 page-size 影响：4 KiB page 使用 256.97 MB，64 KiB page 使用 233.18 MB（-9.26%）。`events` 表的 page 内未使用字节从 30.25 MB 降至 6.95 MB，索引则从 5.92 MB 变为 6.03 MB。在该成对运行中，完整写入、完整读取与后缀读取分别变化 -0.5%、-0.4% 与 -3.8%，fork 变化 -14.8%。因此，空间收益来自更高的大记录 page 利用率，而不是索引缩小或数据省略，并且没有测得延迟退化。
+
+## 考虑过的替代方案
+
+**保留 JSONL level 19。** 不予采用。在扩展语料上，它相对默认级别 frame 可再减少 12.1%，却让完整写入增加 67.0%、fork 增加 129.8%，而完整读取与后缀读取的差异都不足 1%。默认级别 frame 配合来源区间后，相对 master 仍能缩小 14.1%，且没有实质性延迟退化。
+
+**把整份 JSONL 日志压成单个 frame。** 不予采用。该方案可改善跨批次压缩，但后缀读取必须从头解压，也会失去按批次恢复撕裂尾部的能力。
+
+**新建 SQLite 数据库继续使用 4 KiB page。** 不予采用。当前压缩行分布会在 4 KiB B-tree page 之间留下更多不可用空间，使保留字节增加 9.26%。已有数据库保留其 page size，避免改写历史数据。
+
+**从 `events` 移除 ROWID。** 不予采用。复合主键会成为表 B-tree 键并在内部 page 中重复；105 会话对比所得数据库大于使用普通 ROWID 的表。
+
+**对事件内容去重。** 不予采用。消息复述与工具参数只能在依赖重建假设时删除，而 compaction、重试和修剪可能让这些假设失效。物理压缩保留每个事件，不增加重建语义。
+
+**使用逐会话 SQLite 文件或 DuckDB。** 不用于热存储。逐会话文件会失去跨会话查询，DuckDB 的 OLAP 写入模型则更适合冷批量分析，而不是持久 append 批次与低延迟后缀读取。
+
+## 后果
+
+JSONL 保留低成本来源优化，同时避开 level-19 的写入与 fork 代价。SQLite 以实测各项操作约 5–26% 的额外耗时换取 46.8% 的保留体积缩减；其完整写入仍明显快于 JSONL，后缀读取也仍快得多。在这份扩展语料上，完整读取与 fork 略慢于默认级别 JSONL。
+
+新建 SQLite 数据库使用 64 KiB WAL frame 与 cache page。小型数据库可能为稀疏的 schema 与元数据 page 预留更多字节，而实测的多会话工作负载显著改善了 `events` page 利用率。Schema 19 会拒绝其他所有 schema 版本，而不是迁移它们。

+
+## Problem
+
+Provider sign-in for the pi-ai catalog (GitHub Copilot, OpenAI accounts) is moving out of the product into an optional out-of-tree plugin for provider terms-of-service reasons. The plugin needs its sign-in button and attempt UI inside the Models page's provider cards — the surface where a user meets a provider — but `ui-settings-models` rendered its cards from closed code: the only integration path was editing this package, which an external plugin cannot do, and the page's one open seam (`settings.section`) can only add a whole separate page.
+
+## Decision
+
+`ui-settings-models` declares two SlotMap seats in `src/client/slot-contract.ts`, claims them as `children` of its `settings.section` registration, and re-exports their types from `./client` so an out-of-tree plugin can merge them with a type-only import.
+
+`settings.models.provider-card` is `keyed` with `entryKey = ConfigurableProviderView.settingsNs`: one registration under an adapter family's settings namespace receives every card of that family — shipped catalog routes, adopted directory rows, and hand-declared routes alike — while the section never interprets the key. The key domain stays the open string space (no `keyProps` table) because hand-declared route ids are user-chosen at runtime. The seat dispatches on every card that shows a directory row: a saved row's card, its first-run setup posture, and the add-provider draft (its dormant row, `configured: false` in practice), which is where sign-in matters most — the user has just met the provider and holds no key. The hand-declared draft card has no directory row before saving and dispatches nothing. Owner props carry the row's `ConfigurableProviderView`, its `configured` join, and its confirmed api-key credential state (`keyConfigured`, which the first consumer uses to withhold sign-in beside a stored key); nothing more has a current consumer.
+
+`settings.models.footer` is a `list` seat after the rows and the add controls, for section-level extension content such as orphaned-record management.
+
+Without registrants both seats render nothing, so the shipped page is pixel-identical to before.
+
+## Alternatives considered
+
+**A `list` seat with self-filtering registrants instead of keying.** Every registrant would render (and return null) on every card, and two plugins could silently interleave UI inside one family's cards. Keying by namespace gives one accountable extension owner per adapter family and zero wasted dispatches, and reuses the exact pairing rationale of `settings.plugin.item`.
+
+**Keying by provider route id.** Route ids are dynamic — hand-declared routes are named by users at runtime — so a plugin could not register ahead of the rows it wants and would have to churn registrations as the directory changes.
+
+**A `chain` seat replacing the whole card body.** No current consumer needs to replace the editor; the sign-in surface is additive. A takeover contract would also make the section's layout a compatibility surface. A chain can still be added later without disturbing these seats.
+
+**Keeping the sign-in UI wired inside `ui-settings-models` (the pre-plugin design).** Ships the terms-of-service-sensitive surface in the product, which is the outcome this extension point exists to avoid.
+
+## Consequences
+
+An out-of-tree plugin can now integrate per-family card UI into the Models page with no product edits; `llm-pi-ai-oauth` is the first consumer. The cost is a public contract: `ProviderCardExtrasOwnerProps` exposes `ConfigurableProviderView` at the `./client` boundary, and the dispatch sites (saved card, setup posture, add draft, footer) become behavior extensions rely on. Per adapter family the keyed cell renders one owner at a time: a second registration under the same namespace at the same priority is refused by the registry, while a different priority deliberately shadows it (the lowest-priority entry renders) — the slot kit's standard override channel, never a silent merge.

+
+## Problem
+
+出于提供方服务条款的考虑，pi-ai catalog 的提供方登录（GitHub Copilot、OpenAI 账号）正从产品中移出，改由一个可选的仓库外插件承担。该插件需要把登录按钮与登录过程 UI 放进 Models 页的提供方卡片——用户与提供方相遇的界面——但 `ui-settings-models` 的卡片由封闭代码渲染：唯一的集成途径是修改本包，外部插件做不到；页面仅有的开放缝隙（`settings.section`）只能新增一整个独立页面。
+
+## Decision
+
+`ui-settings-models` 在 `src/client/slot-contract.ts` 声明两个 SlotMap 席位，在其 `settings.section` 注册中以 `children` 认领它们，并从 `./client` 再导出其类型，使仓库外插件通过 type-only import 即可获得类型合并。
+
+`settings.models.provider-card` 为 `keyed`，`entryKey = ConfigurableProviderView.settingsNs`：以某适配器家族的 settings namespace 注册一次，即可收到该家族的全部卡片——内置 catalog 路由、从目录采纳的行、手工声明的路由一视同仁——而分区从不解释这个 key。键域保持开放字符串空间（不设 `keyProps` 表），因为手工声明的路由 id 由用户在运行时命名。该席位在每张展示目录行的卡片上分发：已保存行的卡片、其首次运行 setup 形态、以及「添加提供方」草稿卡（其休眠行，实际为 `configured: false`）——草稿卡正是登录价值最大的时刻：用户刚遇到该提供方、手中还没有密钥。手工声明的草稿卡在保存前没有目录行，不分发。Owner props 携带该行的 `ConfigurableProviderView`、其 `configured` 合并结果与已确认的 api-key 凭据状态（`keyConfigured`，首个消费者用它在已存密钥旁抑制登录入口）；更多字段没有现役消费者。
+
+`settings.models.footer` 为 `list` 席位，位于行列表与新增控件之后，承载孤儿记录管理这类分区级扩展内容。
+
+没有注册方时两个席位均不渲染，产品页面与之前逐像素一致。
+
+## Alternatives considered
+
+**用 `list` 席位、由注册方自行筛选，替代按键分发。**每个注册方都会在每张卡片上渲染（再返回 null），且两个插件可能在同一家族的卡片里静默交错 UI。按 namespace 分发让每个适配器家族有唯一可问责的扩展所有者、零浪费分发，并完全复用 `settings.plugin.item` 的配对理由。
+
+**按提供方路由 id 分发。**路由 id 是动态的——手工声明的路由由用户在运行时命名——插件无法先于目标行注册，还得随目录变化反复重注册。
+
+**用 `chain` 席位整体接管卡片。**没有现役消费者需要替换编辑器；登录界面是加法。接管契约还会让分区布局成为兼容面。将来仍可在不动这两个席位的前提下追加 chain。
+
+**把登录 UI 继续织在 `ui-settings-models` 里（插件化之前的设计）。**会把服务条款敏感的界面随产品发布，而这正是本扩展点要避免的结果。
+
+## Consequences
+
+仓库外插件现在无需改动产品即可把按家族的卡片 UI 集成进 Models 页；`llm-pi-ai-oauth` 是首个消费者。代价是一份公开契约：`ProviderCardExtrasOwnerProps` 在 `./client` 边界暴露 `ConfigurableProviderView`，且各分发位点（已保存卡片、setup 形态、新增草稿、footer）成为扩展方依赖的行为。每个适配器家族的 keyed 单元格同一时刻只渲染一个所有者：同一 namespace 下同 priority 的第二次注册会被注册表拒绝，不同 priority 则是刻意的遮蔽（最低 priority 的条目渲染）——这是 slot 套件的标准覆盖通道，绝非静默合并。

+# Agent Note: Preset health resolves the rows it can prove will start
+
+Status: implemented
+
+English | [中文](2026-08-26-preset-health-resolves-rows.zh.md)
+
+## Problem
+
+A preset the roster listed as healthy could still be impossible to compose. Discovery's health check proved the composition parsed in the loader dialect and held named rows, and deliberately stopped there — it resolved no plugin name and applied no config.
+
+This note partly supersedes [broken presets are roster rows](../bug-fix/2026-08-09-broken-preset-roster-rows.md), whose rejected "validating deep" alternative is what shipped here, and it moved the reason off the card face; it also relaxes the shipped-roster assertion [plugin-owned shipped preset root](../bug-fix/2026-08-20-plugin-owned-shipped-preset-root.md) records. Both are updated in place.
+
+`broken` is load-bearing, though, not a card decoration. `presetOptions` drops a broken row from the session pickers so a chooser never defers the discovery to a failed session start, and `resolveMountable` refuses one before spending a mount. Everything downstream therefore reads "not broken" as "will compose".
+
+The gap surfaced when the [repository naming contract](2026-08-11-repository-naming-contract-and-rename-ledger.md) renamed packages under the pre-release stance. In-repo references moved with it; a preset authored under `<dshHome>/.agent-presets` did not, and one naming `@deepseek-ai/dsh-workspace-context` kept its healthy card, kept its place in the picker, and failed only when a person switched to it. A row naming a package a later release renamed or uninstalled is how an authored preset actually rots, and it was exactly the class the check excluded.
+
+The failure it did produce named less than it knew. The Loader's per-row wrapper builds a plain `Error` whose message ends with `cause.message` and keeps the cause only as `error.cause`. A group that fails on two rows therefore arrives as one wrapped row whose message is `failed to apply loader entry <group> (cordis:group): loader entries failed to apply`, with the two real reasons reachable through `cause.errors` alone. The mount diagnostic flattened `AggregateError.errors` and never followed `cause`, so it ended at that line and named neither row.
+
+## Decision
+
+**Discovery resolves each row it can prove will start, and imports nothing.** The resolve pass runs after the shape check in `packages/preset/agent-presets/src/discovery.ts`, so a malformed composition still answers with the shape reason. A package name is looked up on disk — Node's own upward `node_modules` walk, stopping at `<package>/package.json`. A preset-relative or absolute specifier is statted instead, because `import.meta.resolve` only joins URLs for those and a preset shipping a file that was deleted would otherwise pass. Nothing is evaluated either way.
+
+The disk lookup, not `import.meta.resolve`, for two reasons. It is the cheap one: a registered ESM loader hook turns every resolver call into a synchronous round-trip to the hooks thread, measured under the `tsx` hook the source launch installs at 2ms for a hit and 5ms for a miss against 0.055ms and 0.032ms on bare Node — 238ms of resolver time per roster read, where the walk answers the same 135 rows in 0.7ms. It is also the only one that can be asked about the harness at all: `import.meta.resolve`'s `parentURL` argument takes effect only under `--experimental-import-meta-resolve`, which no launch passes, so it resolves from the calling module and would answer about this package rather than about the deployment. The resolver that does honour an explicit parent is the Loader's internal one, whose `resolveSync` signature differs between Node 22 and 24. A Node builtin short-circuits ahead of the walk.
+
+What the walk gives up: a package resolvable only through a loader hook — an import map, or a tree with no `node_modules` — is reported broken. No supported install produces one, because `dsh plugin install` puts every plugin beside the roster.
+
+**One classifier decides where a row resolves.** `src/specifier.ts` owns the split — `cordis:` builtin, preset-relative, absolute file, package name — and both the mount's import override and discovery's check read it. A row discovery resolved from one base while the mount imported it from another would be reported healthy and then fail to load.
+
+**A row that may never start is skipped.** `disabled` is the one entry field the [Loader interpolates](2026-08-11-loader-entry-disabled-interpolation.md): a `!!js` expression evaluates against the loader context at mount time, which discovery cannot do from a file. A row carrying anything but an absent, null, or `false` value is left unchecked, and a disabled group takes its children with it. Every shipped preset gates its shell rows this way, so this is the common shape, not a corner.
+
+**The harness base is a required argument.** `discoverPresets(roots, harnessBase)` and `scanRoot(root, harnessBase)` take it; `AgentPresets` reads `ctx.baseUrl` once in its constructor and throws when it is absent. The base is what makes the question answerable at all — the same package name fails from a preset's own directory and resolves from the installed harness — so an optional one would silently restore the state this check exists to end.
+
+**The mount diagnostic follows a cause that carries more than its message.** `mountDetail` reads branches from `AggregateError.errors`, or from `error.cause.errors` when the cause is an `AggregateError`; a plain cause chain is already flattened into the message and is not followed, which would print every line twice. Nested branches indent under the row that owns them.
+
+**The client puts the reason on the badge.** The card face keeps the preset's own description, because a package specifier tells a chooser nothing they can act on there. The host's reason is revealed by hovering the badge or focusing the card, and a visually hidden `role="alert"` node announces it. A broken card says so through `aria-disabled` rather than `disabled` and refuses the pick in its own handler: `disabled` would take it out of the tab order, and with the reason off the face that would leave anyone without a pointer unable to reach it at all.
+
+**A refused switch says why, where it was refused.** The chip's own label reverts to the preset the session still runs, so without a word the pick simply appears not to have happened. It announces through the shared `Toast`, over the composer column, the way the model picker beside it already reports a rejected selection. Only a pick a person just made is announced — the applier also runs when a session becomes current, and a banner over that would report a refusal nobody asked for. The banner holds for eight seconds rather than the primitive's three, because it carries a cause that names packages and rows; `Toast` gained a `holdMs` for that, which also retired the hazard of a hold constant the stylesheet had to be kept in step with by hand.
+
+The wire already separated the two texts this needs: `message` wraps the cause in the roster's own "preset X failed to mount" frame, while `details.reason` holds the cause alone. A surface that names the preset itself takes the second, or it says the preset twice.
+
+## Alternatives considered
+
+**Check when a preset is selected rather than when the roster is listed.** Rejected. The pickers filter on `broken` before anyone selects, so a preset only checked at selection is still offered, and the reported failure still arrives after the click — the original complaint, relocated. The roster row is where every consumer already reads the verdict.
+
+**Keep the base optional and skip the check without one.** Rejected. Its failure mode is precisely the bug being fixed, delivered with no signal: healthy cards for presets that cannot compose. `ctx.baseUrl` is set on the root before any scoped context derives from it, so the throw is an assertion about something that does not happen rather than a branch with runtime cost.
+
+**Import each row instead of resolving it.** Rejected. Importing runs module top-level code on every roster read, which is a side effect a picker must not have, and it is the mount's job — a plugin that throws on apply or waits forever for a service still fails at the first session, by design.
+
+**Resolve every row through `import.meta.resolve`.** Shipped first and reverted on measurement: correct, and 445ms per roster read, which the client's three concurrent reads turned into 2.45 seconds apiece — the settings section visibly stalled. The resolver is the authority on what imports, but asking it about rows that are plainly installed pays a hooks-thread round-trip for each one.
+
+**Cache the whole of `compositionProblem` on the existing `CompositionStamp`.** Rejected as the answer to the cost: it would have made repeat reads free while leaving the first read of every edited composition at full price, and it keys resolution on the composition file, which does not change when an install does. The walk removed the cost instead, so nothing needs the stamp.
+
+**Send the switch failure to the roster card instead of a banner.** Rejected: the card is exactly where the failures that reach a mount are invisible. A composition whose rows all resolve is reported healthy, so "see the settings page for the reason" points at a card that says the preset is fine.
+
+**Report only the first unresolvable row, matching the shape check.** Rejected. A parse failure can cascade, so naming one is honest there; unresolvable names are independent facts all knowable at once, and reporting them one reload at a time is the avoidable part.
+
+**Follow `error.cause` unconditionally in `mountDetail`.** Rejected. The Loader's wrapper already appends `cause.message` to the message it builds, so a plain chain would render every line twice. An `AggregateError` cause is the one shape whose detail the message drops.
+
+**Keep rendering the reason on the card face.** Rejected. The reason names package specifiers and paths, and a picker card that shows them in place of the preset's description trades what a chooser needs for what a fixer needs — while the fixer's copy is one hover away either way.
+
+**Reuse the icon row's `data-tip` pseudo-element for the tooltip.** Rejected once measured: generated content joins an element's accessible text, so the card's aria snapshot grew a second verbatim copy of a reason the alert already carried. A real `aria-hidden` element keeps exactly one accessible copy — and the existing tooltip is one `nowrap` line sized for an icon label, while this one names package specifiers one per line.
+
+**Make the badge itself the focusable control.** Rejected: the badge sits inside the card's own `<button>`, so a focusable trigger there means restructuring the card head. Keeping the card focusable through `aria-disabled` reveals the same tooltip from the same key press and changes no layout. Leaving the reason reachable by pointer alone was rejected too — it was visible without any interaction before this change, so hiding it behind hover is a regression for anyone reading by keyboard rather than a path that never existed.
+
+## Consequences
+
+A preset naming a package that a rename or an uninstall took away is marked on the roster, refused before a mount is spent, and dropped from the pickers — the same treatment a ghost directory already got. The reason names each row at fault, and a failure that survives to mount names every row inside a group rather than the group alone.
+
+Health answers from what is installed, not from what would import: a package present but exporting a file that is missing still reports healthy and still fails at mount. That is the safe direction — under-reporting returns the previous behavior, while a false broken makes a usable preset unselectable — and it keeps the answer out of the build state of any one package. A source checkout is still not an installed host, though, because a shipped row names a package the deployment installs beside the roster: `shipped-root.spec.ts` asserts the shipped presets carry no reason other than unresolved rows rather than no reason at all. The mount fixtures name a module that loads and then refuses, since a fixture naming a file that does not exist can no longer reach the mount.
+
+A mount failure is now legible where it happens, which matters most for the failures health can never catch: a row that resolves and then refuses is reported healthy on the roster forever, so the banner is not a convenience over the card — it is the only account of that failure anywhere.
+
+Measured in the web app on a roster of eleven presets, `agentPreset.list` answers in 14ms cold and 6-8ms after, and the three concurrent reads the client opens with settle in 9ms of wall clock. The same reads took 2.45 seconds each while every row went through the resolver.
+
+`@deepseek-ai/cordis-plugin-group` is a devDependency of `dsh-agent-presets`: the mount fixtures now compose through `cordis:group` the way real presets do, and a preset outside the workspace cannot resolve that package by name, so the app registers it as a builtin and the fixture harness does the same.

+
+## Problem
+
+名单列为健康的 preset，仍可能根本无法组装。发现过程的健康检查只证明组装能以加载器方言解析、由具名行组成，并刻意止步于此——它不解析任何插件名，也不应用任何配置。
+
+本 note 部分取代了[损坏的 preset 是名单行](../bug-fix/2026-08-09-broken-preset-roster-rows.zh.md)：那份 note 在 Alternatives 中否决的「深度校验」正是这里落地的做法，而且原因也已移出卡片正面；它同时放宽了[插件自带内置 preset 根](../bug-fix/2026-08-20-plugin-owned-shipped-preset-root.zh.md)记录的随附名单断言。两份都已就地更新。
+
+但 `broken` 是承重的，不是卡片上的装饰。`presetOptions` 会把损坏的行从会话选择器里滤掉，好让选择的人不必等到会话启动失败才发现；`resolveMountable` 会在花费一次挂载之前拒绝它。因此下游一切都把「不是 broken」读作「能组装」。
+
+这个缺口在[仓库命名契约](2026-08-11-repository-naming-contract-and-rename-ledger.zh.md)按预发布立场重命名包时暴露出来。仓库内的引用随之更新；写在 `<dshHome>/.agent-presets` 下的 preset 没有，于是引用 `@deepseek-ai/dsh-workspace-context` 的那一个保住了健康的卡片、保住了在选择器里的位置，直到有人切换过去才失败。引用了被后续版本改名或卸载的包，正是手写 preset 真正的腐化方式，而它恰好是这项检查排除掉的那一类。
+
+而它真正产出的失败，说得比它知道的还少。加载器的逐行包装构造一个普通 `Error`，其 message 以 `cause.message` 结尾，cause 只留在 `error.cause` 上。于是一个有两行失败的 group，抵达时是一行被包装的行，message 为 `failed to apply loader entry <group> (cordis:group): loader entries failed to apply`，两条真正的原因只能经由 `cause.errors` 取得。挂载诊断只展平 `AggregateError.errors`，从不跟随 `cause`，因此它停在那一行，一行都没点名。
+
+## Decision
+
+**发现过程解析每一行它能证明会启动的行，且不 import 任何东西。** 解析这一趟跑在 `packages/preset/agent-presets/src/discovery.ts` 的形状检查之后，因此格式错误的组装仍然回答形状原因。包名先在磁盘上查——就是 Node 自己那套向上走 `node_modules`、停在 `<包>/package.json` 的做法。preset 相对路径与绝对路径改用 stat，因为对这两类 `import.meta.resolve` 只做 URL 拼接，否则一个丢失了自带文件的 preset 会蒙混过关。两条路都不求值。
+
+用磁盘查找而不是 `import.meta.resolve`，有两个理由。它便宜：只要注册了 ESM loader hook，每一次解析器调用就变成一次到 hooks 线程的同步往返，在源码启动所用的 `tsx` hook 下实测命中 2ms、未命中 5ms，而裸 Node 分别是 0.055ms 与 0.032ms——每次名单读取要背上 238ms 的解析器时间，而同样这 135 行磁盘走法只要 0.7ms。它也是唯一问得到「宿主」的：`import.meta.resolve` 的 `parentURL` 参数只在 `--experimental-import-meta-resolve` 下生效，而没有任何启动方式传它，因此它是相对调用方模块解析的，回答的是关于本包而不是关于部署的问题。真正认显式 parent 的是 Loader 的内部解析器，而它的 `resolveSync` 在 Node 22 与 24 上签名不同。Node 内建模块在磁盘查找之前直接短路。
+
+磁盘走法放弃了什么：只有经由 loader hook 才能解析的包——import map，或根本没有 `node_modules` 的目录树——会被报为损坏。任何受支持的安装都不会产出这种情况，因为 `dsh plugin install` 会把每个插件装在名单旁边。
+
+**只有一个分类器决定一行在哪里解析。** `src/specifier.ts` 拥有这个划分——`cordis:` 内建、preset 相对、绝对文件、包名——挂载的 import 覆写与发现过程的检查都读它。若发现过程按一个基准解析、而挂载按另一个基准 import，那一行会被报告为健康，然后加载失败。
+
+**可能永远不会启动的行被跳过。** `disabled` 是[加载器唯一会插值](2026-08-11-loader-entry-disabled-interpolation.zh.md)的条目字段：`!!js` 表达式在挂载时对加载器上下文求值，而发现过程无法仅凭文件做到。凡该字段不是缺失、null 或 `false` 的行都不做检查，被禁用的 group 连同其子行一起跳过。每个随附 preset 都用这种方式为 shell 行设门，所以这是常见形状，不是边角。
+
+**harness base 是必填参数。** `discoverPresets(roots, harnessBase)` 与 `scanRoot(root, harnessBase)` 都接收它；`AgentPresets` 在构造函数里读一次 `ctx.baseUrl`，缺失就抛。基准正是让这个问题可回答的前提——同一个包名从 preset 自己的目录解析会失败、从已安装的 harness 解析会成功——所以做成可选就等于悄悄恢复这项检查要终结的那个状态。
+
+**挂载诊断跟随携带信息多于自身 message 的 cause。** `mountDetail` 从 `AggregateError.errors` 取分支，或在 cause 是 `AggregateError` 时从 `error.cause.errors` 取；普通的 cause 链已被展平进 message，不再跟随，否则每一行都会打印两遍。嵌套分支在拥有它的那一行下缩进。
+
+**客户端把原因放到徽标上。** 卡片正面保留 preset 自己的描述，因为在那里一个包说明符不足以让选择的人采取行动。宿主给出的原因在悬停徽标或聚焦卡片时展开，另有一个视觉隐藏的 `role="alert"` 节点负责朗读。损坏的卡片用 `aria-disabled` 而非 `disabled` 表达这件事，并在自己的处理函数里拒绝这次选择：`disabled` 会把它移出 tab 序列，而原因已不在正面，那等于让不用指针的人完全够不到它。
+
+**被拒绝的切换要在被拒绝的地方说明原因。** chip 的标签会弹回会话仍在运行的那个 preset，因此不说话的话，这次选择看起来就像根本没发生。它经由共享的 `Toast` 在 composer 列上方自报，与旁边的模型选择器报告被拒绝的选择方式一致。只有人刚做出的选择会被自报——应用器在会话成为当前会话时也会运行，为那种情况弹横幅等于报告一个没人问过的拒绝。横幅停留八秒而非 primitive 默认的三秒，因为它承载的原因要点名包与行；`Toast` 为此获得了 `holdMs`，顺带也消除了「停留常量必须由人手与样式表保持同步」这一隐患。
+
+线上本来就把这需要的两段文本分开了：`message` 把原因裹进名单自己的「preset X failed to mount」框架，而 `details.reason` 只保留原因本身。自己会点名 preset 的表面取后者，否则会把 preset 说两遍。
+
+## Alternatives considered
+
+**在选中 preset 时检查，而不是在列出名单时。** 否决。选择器在任何人选中之前就按 `broken` 过滤，因此只在选中时检查的 preset 仍会被摆出来，报出的失败仍在点击之后到达——原本的抱怨只是换了个位置。名单行才是每个消费者已经在读判定的地方。
+
+**让 base 可选，没有它就跳过检查。** 否决。它的失败模式正是要修的这个 bug，而且不带任何信号：无法组装的 preset 顶着健康卡片。`ctx.baseUrl` 在任何作用域上下文派生之前就设在根上，因此这个抛出是对「不会发生的事」的断言，而不是一条有运行时代价的分支。
+
+**import 每一行而不是解析它。** 否决。import 会在每次读取名单时执行模块顶层代码，这是选择器不该有的副作用，而且那是挂载的职责——在 apply 时抛错、或永远等待某个服务的插件仍按设计在第一个会话处失败。
+
+**每一行都交给 `import.meta.resolve` 解析。** 先这样发出去，实测后回退：它是对的，但每次名单读取要 445ms，而客户端并发的三次读取把它放大成每次 2.45 秒——设置分区肉眼可见地卡住。解析器确实是「什么能 import」的权威，但为明摆着装好的行去问它，等于为每一行付一次 hooks 线程往返。
+
+**把整个 `compositionProblem` 缓存在已有的 `CompositionStamp` 上。** 作为省开销的手段被否决：它只能让重复读取免费，每个被编辑过的组装的第一次读取仍是全价；而且它把解析结果挂在组装文件上，可安装状态变化时组装文件并不会变。改用磁盘查找直接消掉了开销，于是没有什么还需要这个 stamp。
+
+**把切换失败送到名单卡片上，而不是弹横幅。** 否决：卡片恰恰是那些能走到挂载的失败看不见的地方。所有行都能解析的组装会被报告为健康，于是「去设置页看原因」指向的是一张写着「这个 preset 没问题」的卡片。
+
+**只报第一个无法解析的行，与形状检查保持一致。** 否决。解析失败会连锁，所以在那里只点名一个是诚实的；无法解析的名字是彼此独立、一次即可全部知晓的事实，而一次重载只修一个才是可以避免的部分。
+
+**在 `mountDetail` 里无条件跟随 `error.cause`。** 否决。加载器的包装已经把 `cause.message` 追加进它构造的 message，因此普通链会把每一行渲染两遍。`AggregateError` 类型的 cause 是唯一被 message 丢掉细节的形状。
+
+**继续把原因渲染在卡片正面。** 否决。原因里是包说明符和路径，把它们摆在 preset 描述的位置，等于用选择者需要的东西换取修复者需要的东西——而修复者需要的那份，无论如何都只隔一次悬停。
+
+**复用图标行的 `data-tip` 伪元素来做提示条。** 实测后否决：生成内容会并入元素的可访问文本，因此卡片的 aria 快照多出一份 alert 已经携带的原因的逐字副本。改用真实的 `aria-hidden` 元素后，可访问副本恰好只有一份——而且既有那条提示条是为图标标签准备的单行 `nowrap`，这一条要逐行列出包说明符。
+
+**把徽标本身做成可聚焦控件。** 否决：徽标位于卡片自身的 `<button>` 内部，在那里放可聚焦触发器意味着改造卡片头部结构。用 `aria-disabled` 让卡片保持可聚焦，同一次按键就能展开同一条提示条，且不改动任何布局。「原因只用指针可达」同样被否决——这次改动之前它无需任何交互就可见，因此把它藏到悬停之后，对用键盘阅读的人是退化，而不是一条本就不存在的路径。
+
+## Consequences
+
+引用了被改名或卸载掉的包的 preset，会在名单上被标出、在花费挂载之前被拒绝、并从选择器里剔除——与幽灵目录早已得到的待遇一致。原因会点名每一个出问题的行；而活到挂载阶段的失败，会点名 group 内的每一行，而不只是 group 本身。
+
+健康依据的是「装没装」，而不是「能不能 import」：包在、但导出指向的文件不在，仍会报告健康并仍在挂载时失败。这是安全的方向——漏报只是退回先前的行为，而误报会让一个可用的 preset 变得不可选——而且它让答案不依赖于任何单个包的构建状态。不过源码检出仍不是已安装宿主，因为随附行引用的是部署与名单装在一起的包：`shipped-root.spec.ts` 断言随附 preset 除未解析行之外不携带其他原因，而不是不携带任何原因。挂载夹具改为引用一个能加载、随后拒绝的模块，因为引用不存在文件的夹具已经到不了挂载。
+
+挂载失败现在在它发生的地方就可读，这对健康永远抓不到的那类失败最要紧：能解析、随后拒绝的行在名单上永远显示健康，因此这条横幅不是卡片之外的一份便利——它是那类失败在任何地方唯一的交代。
+
+在 web 应用中对十一个 preset 的名单实测：`agentPreset.list` 冷启动 14ms、之后 6–8ms，客户端开场并发的三次读取合计 9ms wall。在每一行都过解析器的版本里，同样这三次读取各要 2.45 秒。
+
+`@deepseek-ai/cordis-plugin-group` 成为 `dsh-agent-presets` 的 devDependency：挂载夹具现在像真实 preset 那样经由 `cordis:group` 组装，而工作区之外的 preset 无法按名解析该包，所以应用把它注册为内建，夹具 harness 也照做。

 Discovery owns health, and a damaged directory is a **roster row carrying a `broken` reason**, never a gap. `scanRoot` treats every directory whose name is a usable preset id as a preset slot: composition missing → broken ("still occupies the id; delete it or restore the file"), composition unreadable/unparsable/not-a-list-of-named-rows → broken with the parser's first line. The shape check parses with the loader's own `entryListSchema` (the `!!js` dialect), so health can never call broken what the loader would accept; directories whose names fail `PRESET_ID` are skipped outright, because no copy could ever collide with them. `broken` rides `AgentPreset`, the `agentPreset.list` wire entry, and the UI row. Mounting paths (`mount`/`recompose`/`standingKeyFor`) refuse a broken preset up front via `resolveMountable` with the discovery-reported reason; `resolve` still answers (delete/read/report need the row), and `copy`'s roster check now sees ghosts, which turns the "already exists" refusal actionable — the broken card to delete is on the same page.

 ## Testing
 
-`shipped-root.spec.ts` covers the plugin ownership directly: a bare roster lists the four shipped presets healthy and `system`-trusted (proving the moved files resolve from the package), the shipped root precedes configured roots and the derived user root with a fixture directory claiming a shipped id shadowed, and `includeShippedRoot: false` mounts the roster without the set. Existing suites that pin exact rosters opt out, which the option's documentation names as its second purpose.

+# Agent Note: Composer e2e gestures gate on the contenteditable attribute
+
+Status: implemented
+
+English | [中文](2026-08-26-composer-gesture-editable-gate.zh.md)
+
+## Problem
+
+Two Playwright gesture semantics silently changed when the composer became a Lexical `contenteditable` `<div>`, and both bit only under CI load. While the input machine is adjudicating or submitting a send — and in every locked state — the composer renders read-only by flipping `contenteditable` to `"false"` on the same element. On that element `fill()` throws immediately (`Element is not an <input>, <textarea> or [contenteditable] element`) instead of waiting through actionability, and `expect.poll(() => input.isEnabled())` is a no-op guard: Playwright's enablement check ignores both `aria-disabled` and `contenteditable` on a `<div>`, so it reports `true` throughout the read-only window. The exposed race is only a few frames wide — the permission-policy scenario stayed green for weeks until a Remote-routed subagent refactor stretched submit settling enough for CI to land inside it.
+
+## Decision
+
+Composer e2e gestures go through `writeComposerDraft` in `apps/web/tests/support.ts`, which waits for the editable attribute on the gesture's own target (`input.and(page.locator('[contenteditable="true"]'))`) before acting and replaces the draft with per-key strokes. Scenario code that must wait for the composer to reopen after a submit gates on the `contenteditable` attribute, never on `isEnabled()`.
+
+## Alternatives considered
+
+- **Waiting inside each scenario** instead of inside the helper: rejected — every new scenario re-discovers the trap the hard way, and the fix that motivated this note was already the second such site.
+- **Keeping `fill()` and polling `aria-disabled`** before each call: rejected — it leaves the dropped-edit race `fill()` has directly after trigger-menu and chip interactions (Lexical's internal selection lags the DOM selection inside one task), which the per-key helper also covers.
+- **Making the product surface tolerate `fill()`** (accepting synthetic edits while read-only): rejected — the read-only window is deliberate UI truth during submit adjudication; loosening it for tests would change user-visible behavior.
+
+## Consequences
+
+- A bare `input.fill(...)` against `[data-composer-input]` is a latent CI race even when it passes locally; the helper is the supported gesture.
+- `isEnabled()` on the composer asserts nothing. Existing polls of it guard nothing and read as coverage they do not provide.
+- A running turn by itself keeps the composer editable — that is what queueing types into — so the gate waits only through submit adjudication and locked states, not for turn completion.

+
+Status: implemented
+
+[English](2026-08-26-composer-gesture-editable-gate.md) | 中文
+
+## 问题
+
+composer 变为 Lexical `contenteditable` `<div>` 后，两个 Playwright 手势语义悄然改变，且都只在 CI 高负载下咬人。输入机在裁决或发送一次提交期间——以及所有 locked 状态下——composer 通过把同一元素的 `contenteditable` 翻成 `"false"` 呈现只读。在该元素上 `fill()` 立即抛错（`Element is not an <input>, <textarea> or [contenteditable] element`）而不再经 actionability 等待；`expect.poll(() => input.isEnabled())` 则是无效护栏：Playwright 的 enablement 检查对 `<div>` 同时无视 `aria-disabled` 与 `contenteditable`，整个只读窗口内一律报 `true`。暴露的竞态只有几帧宽——permission-policy 场景绿了数周，直到 subagent 控制 Remote 化把提交 settle 拉长，CI 才落进窗口。
+
+## 决策
+
+composer 的 e2e 手势统一走 `apps/web/tests/support.ts` 的 `writeComposerDraft`：动作前在手势自身的目标上等待可编辑属性（`input.and(page.locator('[contenteditable="true"]'))`），再以逐键击键替换草稿。场景代码若需等待提交后 composer 重新开放，一律以 `contenteditable` 属性为门，永不使用 `isEnabled()`。
+
+## 曾考虑的替代方案
+
+- **在各场景内各自等待**而不是收进 helper：否决——每个新场景都会以最痛的方式重新发现这个陷阱，而促成本 note 的修复本身已是第二个踩点。
+- **保留 `fill()`、每次调用前 poll `aria-disabled`**：否决——这仍留着 `fill()` 在触发菜单与 chip 交互之后的丢编辑竞态（单 task 内 Lexical 内部 selection 落后于 DOM selection），逐键 helper 同时覆盖了它。
+- **让产品表面容忍 `fill()`**（只读期间接受合成编辑）：否决——只读窗口是提交裁决期间刻意的 UI 事实；为测试放松它会改变用户可见行为。
+
+## 后果
+
+- 对 `[data-composer-input]` 裸写 `input.fill(...)` 即使本地全绿也是潜伏的 CI 竞态；helper 是受支持的手势。
+- 对 composer 调用 `isEnabled()` 断言不了任何东西。既有的此类 poll 不护任何路径，却读起来像提供了覆盖。
+- turn 运行本身保持 composer 可编辑——排队输入正是打进这里——因此该门只等待提交裁决与 locked 状态，不等待 turn 完成。

+# Agent Note: pi-ai grant payloads store their JSON image
+
+Status: implemented
+
+English | [中文](2026-08-26-pi-ai-grant-payload-json-image.zh.md)
+
+## Problem
+
+A GitHub Copilot sign-in against github.com failed at its commit step: `credentials-local: record "llm-pi-ai/github-copilot" payload holds a value JSON cannot represent`. pi-ai's Copilot credential carries its optional members as explicit `undefined` (`enterpriseUrl: undefined` when no Enterprise domain was given — idiomatic JavaScript that `JSON.stringify` would simply drop), and `llm-pi-ai`'s store bridge committed the credential object verbatim as the grant payload. The credential store's validator rightly refuses `undefined` as unrepresentable, so every grant whose flow left an optional member unset failed to store, and the sign-in reported failure after the provider had already authorized it.
+
+## Decision
+
+`toRecord` in `packages/llm/llm-pi-ai/src/auth.ts` stores the JSON image of a grant credential: `jsonImage` drops explicitly-undefined members of plain objects and renders undefined array entries as `null`, exactly as `JSON.stringify` would. Everything else — non-finite numbers, foreign-prototype objects — passes through untouched, so a genuinely unstorable value still fails loud at the store's validator rather than being silently reshaped. Reading back is unchanged: an absent member and an explicitly-undefined one are indistinguishable to pi-ai's consumers, which access optional members by property read.
+
+## Testing
+
+`tests/auth.spec.ts` writes the Copilot-shaped grant (explicit `undefined` member, nested drop, array hole) through the real `LocalCredentialProvider` and asserts the stored payload is the JSON image; a second case proves the fail-loud path survives by committing a `Date`-valued member and asserting the store's refusal reaches the caller.
+
+## Alternatives considered
+
+**`JSON.parse(JSON.stringify(credential))`.** Rejected: it also renders `NaN`/`Infinity` as `null` and runs `toJSON` methods, silently reshaping exactly the values the strict validator exists to refuse loudly.
+
+**Relaxing the store validator to skip `undefined` members.** Rejected: the seam stores payloads it never reads or reshapes, and every producer relies on byte-faithful round-trips; normalization belongs to the producer that knows its library's idiom, not to the store every plugin shares.
+
+**Fixing pi-ai upstream to omit unset members.** Out of this repository's hands and version-fragile: any future flow reintroducing the idiom would break sign-in again. The bridge owning the translation makes the harness robust against the whole class.
+
+## Consequences
+
+Grants from every pi-ai flow store regardless of which optional members the flow left unset. The bridge now owns a one-way normalization: a payload read back lacks members that were explicitly `undefined` at write time, which is indistinguishable from their absence for property access, and remains the documented JSON semantics.

+
+Status: implemented
+
+[English](2026-08-26-pi-ai-grant-payload-json-image.md) | 中文
+
+## Problem
+
+一次面向 github.com 的 GitHub Copilot 登录在提交环节失败：`credentials-local: record "llm-pi-ai/github-copilot" payload holds a value JSON cannot represent`。pi-ai 的 Copilot 凭据以显式 `undefined` 携带可选成员（未填 Enterprise 域名时为 `enterpriseUrl: undefined`——这是 `JSON.stringify` 会直接丢弃的 JavaScript 惯用写法），而 `llm-pi-ai` 的存储桥接把凭据对象原样作为 grant payload 提交。凭据存储的校验器正当地拒绝 `undefined` 为不可表示，于是所有流程留有未填可选成员的 grant 都无法落盘，提供方已经完成授权之后登录却报失败。
+
+## Decision
+
+`packages/llm/llm-pi-ai/src/auth.ts` 的 `toRecord` 改为落盘 grant 凭据的 JSON 像：`jsonImage` 丢弃普通对象里显式为 undefined 的成员，把数组中的 undefined 条目渲染为 `null`，与 `JSON.stringify` 完全一致。其余一切——非有限数、异种原型对象——原样透传，因此真正不可存储的值仍会在存储校验器处大声失败，而不是被静默改写。读回不变：成员缺失与显式 undefined 对以属性读取访问可选成员的 pi-ai 消费方不可区分。
+
+## Testing
+
+`tests/auth.spec.ts` 经真实 `LocalCredentialProvider` 写入 Copilot 形状的 grant（显式 `undefined` 成员、嵌套丢弃、数组空洞），断言落盘 payload 为 JSON 像；第二个用例提交带 `Date` 成员的 grant 并断言存储的拒绝到达调用方，证明 fail-loud 路径仍在。
+
+## Alternatives considered
+
+**`JSON.parse(JSON.stringify(credential))`。**否决：它还会把 `NaN`/`Infinity` 渲染为 `null` 并执行 `toJSON` 方法，把严格校验器本要大声拒绝的值静默改写掉。
+
+**放宽存储校验器、跳过 undefined 成员。**否决：seam 存储的 payload 它从不读取或改写，所有生产方都依赖逐字节往返；归一化属于了解自家库惯用法的生产方，而不是所有插件共享的存储。
+
+**在 pi-ai 上游修掉未填成员。**不在本仓库掌控内且随版本脆弱：将来任何流程重新引入该惯用法都会再次弄坏登录。由桥接层拥有这次翻译，让 harness 对整类问题免疫。
+
+## Consequences
+
+所有 pi-ai 流程的 grant 无论留空哪些可选成员都能落盘。桥接层现在拥有一次单向归一化：写入时显式为 undefined 的成员在读回时缺失，这对属性访问不可区分，且正是文档化的 JSON 语义。

+# Agent Note: Question drafts survive Session switches
+
+Status: implemented
+
+English | [中文](2026-08-26-question-drafts-survive-session-switch.zh.md)
+
+## Problem
+
+`conversation.composer` is a strict Session-scoped slot, so selecting another Session unmounts its question entry. The generic `QuestionFlow` kept its current question index, selected labels, custom text, and skip flags in React component state. A still-pending request therefore returned with empty answers after an A → B → A Session switch even though the pending carrier remained owned by Session A.
+
+The draft is transient presentation state: it must follow its Session within the current page, but it must not become mutable state on the pending business carrier or a user preference synchronized through Host settings.
+
+## Decision
+
+The question entry declares a non-persisted `createQuestionDraftStore` handle when it registers into `conversation.composer`. The renderer owns one instance per Session scope and retains that instance across selection changes, so remounting the same Session reads the same progress.
+
+The store holds at most one request identity and one progress value: current question index plus one selected/custom/skipped draft per question. `QuestionFlow` reads the stored value only when the local pending-request key and question count match. A new request therefore renders empty immediately and its first write atomically replaces the older value instead of accumulating request records. Successful answer and cancellation settlements clear only their matching request key, so a stale completion cannot erase a later draft.
+
+Busy state, failure feedback, collapse state, and focus bookkeeping remain component-local because they describe the mounted interaction rather than the unfinished answer. The `plan-review` presentation has no multi-question draft and does not read the store.
+
+This realizes the existing [Session-scope rule](../architecture/2026-07-25-web-client-session-scope-and-provide-channel.md) that remount-surviving state belongs in a Session-bound source, while retaining the [Host-backed preference decision](2026-08-06-host-backed-web-preferences.md): drafts remain page-local and never enter settings, `localStorage`, or disk. The answer semantics from [multi-select custom composition](2026-07-30-multi-select-custom-answer-composition.md) are unchanged.
+
+## Testing
+
+The store test pins keyed replacement and stale-cleanup isolation. The component test unmounts and remounts the strict entry over one store instance and requires its page, selected option, and custom text to return. The keyless assembled Web scenario types both answer forms, switches to a new Session, returns to the waiting Session, snapshots the restored composer, and submits the restored values through the real question waterfall.
+
+## Alternatives considered
+
+**Keep the state in `QuestionFlow`.** Rejected because a strict Session switch deliberately destroys that React instance; a component-local key cannot outlive the unmount it is intended to identify.
+
+**Put mutable drafts on `PendingQuestion`.** Rejected because the carrier represents pending request settlement, not React presentation state, and mutations there would bypass the Slot store's subscribed read/write surface and lifecycle ownership.
+
+**Use a module-level map keyed by Session and request.** Rejected because plugin reload and Session pruning would not own its disposal, and completed request entries could accumulate independently of the renderer's scope lifecycle.
+
+**Persist drafts through Host settings or browser storage.** Rejected because switching Sessions within one page needs remount continuity, not cross-page or cross-process durability. Persistence would synchronize transient answer text beyond the interaction that owns it.
+
+## Consequences
+
+Unsubmitted generic-question answers survive ordinary Session navigation in the current page, including the current question and explicit skips. They still reset after a page reload, Session-scope prune, or replacement pending-request identity. The per-Session memory cost is bounded to one request progress value and is released with the Slot store's Session scope.

+# Agent Note: 提问草稿在 Session 切换后保留
+
+Status: implemented
+
+[English](2026-08-26-question-drafts-survive-session-switch.md) | 中文
+
+## Problem
+
+`conversation.composer` 是严格按 Session 划分 scope 的 slot，因此选择另一个 Session 会卸载其提问条目。通用 `QuestionFlow` 把当前题号、已选标签、自定义文本和跳过标记保存在 React 组件状态中。因此，即使待处理载体仍归 Session A 所有，一个仍在等待的请求经过 A → B → A 的 Session 切换后，也会以空答案重新出现。
+
+草稿是临时呈现状态：它必须在当前页面内跟随所属 Session，但不能变成待处理业务载体上的可变状态，也不能成为通过 Host settings 同步的用户偏好。
+
+## Decision
+
+提问条目注册到 `conversation.composer` 时声明一个非持久化的 `createQuestionDraftStore` handle。renderer 为每个 Session scope 拥有一个实例，并在选择切换期间保留该实例，因此重新挂载同一 Session 时会读到相同进度。
+
+store 最多保存一个请求标识和一个进度值：当前题号，以及每道题各一份 selected/custom/skipped 草稿。只有本地待处理请求 key 与题目数量都相符时，`QuestionFlow` 才读取已存值。因此，新请求会立即渲染为空，并在首次写入时原子替换旧值，而不会累积请求记录。成功回答和取消落定后只清除与自身相符的请求 key，因此过期的完成动作不会删除较新的草稿。
+
+忙碌状态、失败提示、折叠状态和焦点记录仍留在组件本地，因为它们描述当前已挂载交互，而不是未完成的答案。`plan-review` 呈现界面没有多题草稿，也不读取该 store。
+
+这落实了既有的 [Session scope 规则](../architecture/2026-07-25-web-client-session-scope-and-provide-channel.zh.md)：需要跨重新挂载保留的状态应归 Session 绑定的数据源；同时保留[由 Host 持久化偏好的决策](2026-08-06-host-backed-web-preferences.zh.md)：草稿仍只存在于当前页面，从不进入 settings、`localStorage` 或磁盘。[多选自定义答案组合](2026-07-30-multi-select-custom-answer-composition.zh.md)规定的答案语义保持不变。
+
+## Testing
+
+store 测试固定按 key 替换和过期清理隔离。组件测试在同一个 store 实例上卸载并重新挂载严格 Session 条目，并要求题号、已选选项和自定义文本全部恢复。无密钥的组装 Web 场景会输入两种答案、切换到新 Session、返回仍在等待的 Session、对恢复后的编辑器生成快照，再经真实提问 waterfall 提交恢复的值。
+
+## Alternatives considered
+
+**继续把状态留在 `QuestionFlow`。** 不采用，因为严格 Session 切换会刻意销毁该 React 实例；组件本地 key 无法比其试图标识的卸载过程活得更久。
+
+**把可变草稿放进 `PendingQuestion`。** 不采用，因为载体表示待处理请求的落定过程，而不是 React 呈现状态；在其中做变更还会绕过 Slot store 提供的订阅读写界面和生命周期归属。
+
+**使用按 Session 和请求建立索引的模块级 map。** 不采用，因为 plugin 重载与 Session 裁剪不拥有其清理过程，已完成请求的条目还可能脱离 renderer 的 scope 生命周期不断累积。
+
+**通过 Host settings 或浏览器存储持久化草稿。** 不采用，因为同一页面内切换 Session 需要的是跨重新挂载连续性，而不是跨页面或跨进程耐久性。持久化会把临时答案文本同步到拥有它的交互之外。
+
+## Consequences
+
+未提交的通用提问答案现在能在当前页面的普通 Session 导航中保留，包括当前题号和显式跳过状态。刷新页面、Session scope 被裁剪或待处理请求标识被替换后，草稿仍会重置。每个 Session 的内存成本被限制为一个请求进度值，并随 Slot store 的 Session scope 一起释放。

+Each production entry point resolves the VitePress configuration, requires `outDir` to be a proper child of the site root, and requires its nearest existing parent to resolve inside the real site root. It unlinks a link-shaped output without traversing its target and removes a real output directory before bundling. This project-owned preparation covers MPA builds, which do not empty their final output directory, and prevents removed routes or assets from surviving a rebuild. The later raw-twin pass treats files created by the current VitePress build as occupied: a twin or image may never overwrite one, such as a `public/` copy, and a name collision fails the emission.
 
 `llms.txt` is generated from the publication manifest at the site root: both locale trees in sidebar order, one `- [label](<base><route>): <section>` row per page, links site-absolute under the deploy-time `DOCS_BASE`. Locale homes stay out — the file itself is the agent entry point.

-The chain is two halves with one contract: the node half owns bundle detection and notification, the browser half owns the swap. The node half runs one interval that stat-polls each graph bundle and optional source map from the module host's pre-read baseline. An unchanged startup row starts watching without a content read or hash; a changed row, or a dirty row whose artifact reappears, enters `rebuilt()`, and only real revision changes are broadcast. It also serves `/plugins/events`, an SSE channel broadcasting `graph` and `rebuilt` frames.
