The alternative (a merge-extensible `session/meta` event as log line 0) was rejected: an in-log event would ride along with a seeded/forked session for free, but metadata is not replayable state, so the explicit out-of-log header seam is the cleaner cost.

A route key had to name an installed provider (`resolveProfiles` rejected anything else), model listing returned `getBuiltinModels(provider)` verbatim, and request-time model resolution looked the id up in that same catalog and overrode only `baseURL`. Three consequences followed, and all three were dead ends rather than gaps: an OpenAI-compatible gateway, a self-hosted server, or a provider newer than the installed catalog could not be configured at all; a model the catalog had not caught up with failed with `UNKNOWN_MODEL` even against a correct endpoint; and a model's context window and output cap were whatever the pinned pi-ai release said, so a deployment could neither correct a stale value nor supply one for a model pi-ai had never described. Upgrading the package was the only way to move any of it. + +The adapter also streamed through `streamSimple` from `@earendil-works/pi-ai/compat`, an entry point whose own module documentation declares it a temporary compatibility surface — its catalog reads are `@deprecated`, and it is deleted when pi-ai finishes its `ModelManager` migration. The three configuration limits and the deprecated dependency have the same fix, because pi-ai's supported runtime (`createModels()` / `createProvider()`) is built around a provider being *declared* rather than looked up. + +## Decision + +A provider route is a **declaration**, and the installed catalog is its default. `resolveProfiles` no longer checks route keys against `getBuiltinProviders()`. Instead each route resolves to a materialized model list plus the pi-ai `Provider` that serves it: + +- `catalog.ts` merges the installed catalog under the profile's own entries. A profile's `models` list *replaces* the route's catalog (an absent or empty list serves it unchanged), and each entry defaults its unset fields from the installed model of the same `id`. Only the fields the harness consumes are configurable — `id`, `name`, `contextWindow`, `maxTokens`. Pricing and input modalities are absent from the surface because nothing reads them: `replay.ts` zeroes pi-ai's cost metadata and `context.ts` keeps only text blocks. Reasoning is absent for a different reason: a bare capability flag would make pi-ai advertise effort levels with no `thinkingLevelMap` to spell them, so it rides the installed entry or is absent. Materialization spreads the installed entry and overrides those four fields, rather than enumerating the result: an enumerated rebuild silently drops every `Model` field this package does not model, which is how `headers` went missing from an nvidia route once already. +- `provider.ts` builds the route's `Provider`. A catalog route that keeps its catalog protocol **reuses** the installed provider with `getModels()` replaced; every other route is built by `createProvider()` over a protocol table whose entries are the same `@earendil-works/pi-ai/api/*.lazy` factories pi-ai's own provider factories use. That table is narrower than pi-ai's full API set on purpose — it holds only protocols a profile can completely describe with a key, an endpoint, and headers, so Bedrock (SigV4 plus a region), Vertex (project, location, ADC), Azure (provider environment plus an api-version), and Codex (OAuth) are absent rather than offered as routes that cannot authenticate. Catalog routes still reach them through their own provider; only an explicit override is refused. +- `adapter.ts` turns each resolution into an **immutable snapshot** — the profiles plus a `createModels()` collection holding those providers — and every operation captures a whole snapshot before its first `await`. +- A model's **explicitly configured** `maxTokens` becomes the seam's `defaultMaxTokens`. The value inherited from the installed catalog does not: pi-ai requires `Model.maxTokens` as the model's output *capability*, while `defaultMaxTokens` is a cap the deployment chose to send on requests that name none, and materializing the former as the latter would start capping every request at a number nobody picked. + +### Snapshots, not a shared collection + +`Models.streamSimple()` resolves its provider lazily, when the returned stream is first consumed — which is after the adapter has awaited the route's credential. A single collection mutated in place would therefore let a request that started under one configuration finish under another, or fail on a provider that no longer exists, even though `llm.prepareCall()` already froze that step's config and captured its adapter registration. A configuration change builds a *new* collection and leaves the one in use alone, so the seam's per-step freeze holds all the way down: switching models mid-reply takes effect on the next step, never inside the one in flight. + +### The directory replaces atomically + +The configurable-provider directory follows the profiles, so it changes whenever a declared route appears or leaves. Withdrawing the old registration and making a new one cannot express that: a candidate set the registry refuses — a profile keyed `deepseek-official`, which `llm-deepseek` already declares — would leave this plugin's whole directory withdrawn and the Models page empty, silently, because the settings-change callback contains the failure. `registerConfigurableProviders` therefore returns a handle carrying `replace(entries)` with the same validate-the-candidate-set-first atomicity `registerAdapter` has, and the plugin uses it. A refused swap costs a diagnostic; the previous entries keep serving. + +Resolution fails loud and names the route and model at fault: a model the catalog does not describe falls back to the route's own `defaultContextWindow`/`defaultMaxTokens`, so a listing that discloses nothing but ids still yields a serviceable route; a route the catalog does not ship needs `api`, `baseURL`, and a non-empty `models` list. Because the built `Provider` is part of the resolution result, a protocol or model error keeps the last good route set serving, exactly as a bad settings snapshot already did. + +The configurable-provider directory is now the installed catalog **joined with** every route the current profiles declare, re-registered when that set changes. Without the join a hand-declared route would have no settings address and no configuration surface could show or edit it. + +### A capability whose only level does nothing is reported unavailable + +pi-ai reports a model with no reasoning metadata as supporting the single level `off`, and the adapter used to pass that straight through. It reaches the seam as a one-item effort list, which every surface renders as a picker holding one selectable control — and that control is a lie: `off` becomes an *omitted* reasoning option at dispatch, byte-for-byte the request that naming no effort already produces. A provider whose own default is to think keeps thinking while the surface shows `off` selected. + +`reasoningInfo` therefore omits the seam's `reasoning` field whenever `model.reasoning` is falsy. The condition is the model's own metadata, not where the model came from, so this covers every hand-declared model **and** the 251 installed-catalog models pi-ai marks as non-reasoning. Those previously offered the lone `off`; they now offer nothing, and the surface shows the provider default alone. Models that do carry reasoning metadata are untouched — their level list still crosses the seam unfiltered, `off` included, because there it selects between real alternatives. + +### Credentials stay outside pi-ai + +pi-ai's `Models` carries its own credential concept — a `CredentialStore` keyed by provider id, with `envApiKeyAuth` resolving `credential.key ?? env(VAR)`. Adopting it would have created a second credential source of truth beside `ctx.credentials` and, worse, reintroduced the ambient fallback the harness deliberately forbids: a named-but-missing `apiKeyEnv` must fail with `MISSING_CREDENTIAL` rather than authenticate with whatever unrelated key the environment holds. + +`ModelsImpl.applyAuth` honours `options.apiKey` as the request's key, but only through a provider that declares an api-key method: `resolveProviderAuth` short-circuits to that method when the override is present, and otherwise falls through to the credential store and then to ambient discovery, returning nothing — and so failing the request with `Provider is not configured` — when the provider has no api-key method at all. The harness therefore resolves the route's key through its own seam, as before, and passes the result as the request's `apiKey`; the collection is constructed with no credential store. + +A route's auth follows from that. A catalog route keeps the installed provider's own `auth`, which preserves provider-native ambient discovery for a profile naming no credential, and keeps it through an `api` override too: which environment a provider reads is a property of the provider, not of the wire format its models speak. The exception is a catalog provider with no api-key method — `openai-codex` authenticates through OAuth alone — where a profile that names a credential also gets the harness method beside the provider's own, because otherwise its configured key would be refused before any request went out. A keyless profile on such a route adds nothing and keeps the honest refusal: this adapter holds no OAuth store to resolve through. A hand-declared route gets a harness-owned `ApiKeyAuth` that reports configured-but-keyless rather than unconfigured, leaving the requirement to the protocol — which is where it lives: pi-ai's OpenAI-compatible implementation still demands a key or an `Authorization` header, and says so itself. + +## Alternatives considered + +- **Keep `createProvider()` but skip the `Models` collection**, streaming through `provider.streamSimple(model, ctx, {apiKey})`. Smallest diff and the credential path is untouched, but `createProvider`'s `auth` is a required field that this path never invokes — a required-by-signature implementation with no caller. It also leaves `refreshModels` needing a hand-built `RefreshModelsContext`, and keeps the adapter off the runtime pi-ai actually supports. +- **Reuse the installed provider for catalog routes and `createProvider()` only for declared ones**, with no shared resolution. Zero risk to catalog behavior, but catalog materialization, endpoint override, and per-model configuration would each exist twice, and a catalog route that repoints its protocol would have to jump paths mid-resolution. The chosen split confines the asymmetry to provider construction, where it is forced by pi-ai not exposing a built provider's API implementations. +- **Rebuild every route through `createProvider()`**, including catalog ones. Fully symmetric, but a built `Provider` does not expose its `api`, so the protocol table would become the ceiling on which providers work — Bedrock loads its Smithy module through a separate entry point and would silently stop working. +- **Expose pi-ai's whole `Model` shape** (cost, input modalities, `thinkingLevelMap`, `compat`). Maximum configurability, but no current consumer reads those fields, so a configured price or modality would change nothing while reading as supported. + +- **Keep one mutable `Models` collection and re-sync it.** Fewer allocations, and correct for every operation that resolves synchronously. It is exactly wrong for the one that does not: `stream()` awaits a credential between capturing its model and dispatching it. +- **Simulate an atomic directory swap with dispose-then-register.** No seam change, and it works whenever the new set is valid — which is the case that never needed atomicity. +- **A runtime dynamic catalog** — `fetchModels` plus `ModelsStore`, refreshed in the background. Rejected for this change: it makes the model list external mutable state needing cache, invalidation, and an offline path, and the product need is a one-shot discovery action whose result the user adopts into `settings.yaml`. That action belongs to the configuration surface and is deferred with it; `settings.yaml` stays the single source of truth for what a route serves. + +## Consequences + +Configuring a provider no longer depends on a pi-ai release. A gateway, a self-hosted server, or a model newer than the pinned catalog is a `settings.yaml` edit, and a stale context window can be corrected in place. The deprecated `/compat` import is gone, so pi-ai deleting it is no longer a breaking event. `defaultMaxTokens` now flows from configuration when a deployment states one, without inventing a cap from catalog metadata. + +What it costs: `settings.yaml` grows for a declared route, because it must state its endpoint, protocol, and model ids. `api` applies to a whole route, so a mixed-protocol catalog route cannot host a model of the other protocol — splitting it across two route keys is the workaround.

Every existing seam operation is keyed by a registered provider route, so none of them can carry this. + +## Decision + +Interrogation is keyed by **settings namespace**, not by provider route: + +- `ctx.llm.registerModelDiscovery(settingsNs, discover)` lets an adapter plugin offer to interrogate endpoints for the namespace it owns, and `ctx.llm.discoverModels(settingsNs, request)` asks. There is no way to enumerate which namespaces registered: a surface that cannot interrogate learns it from the refusal, and a list nothing consumed would be a required wire field doing nothing. The namespace is the right key because a configuration surface already holds it from the configurable-provider directory, and because a provider being added has no route to name. +- `LlmModelDiscoveryRequest` carries the draft — an optional `provider`, an optional `baseURL`, an optional `api`, an optional `apiKey`, and a signal — and needs at least one of `provider` or `baseURL` to have anything to answer about. `provider` exists because a route the adapter already describes is answered from its own registry with no network call at all; only a route it does not describe reaches an endpoint. Nothing in this path writes settings or credentials. The one read is the credential of a route the request names: a configuration surface holds a redacted descriptor rather than the stored secret, so the draft's `apiKey` is present only while the user is typing one, and without that read an already-configured route would be interrogated unauthenticated and answer 401. The typed key wins, being the one under test. +- `LlmDiscoveredModel` makes every field but `id` optional, because most listings disclose an id and nothing else. The reply is candidates, not a catalog: a surface adopting one still owes the capacities the adapter requires. +- `llm.discoverModels` carries the same draft over the wire. Its `apiKey` is the third and last payload on which a secret may ride, alongside `settings.update`/`mutate` and `credentials.set`, and it is never stored or echoed back. It does ride the client's outgoing envelope like every other secret-bearing payload, where a `subscribeEnvelopes()` observer can see it; redacting that tap is a configuration-plane-wide change, not this method's to make alone. The method is loopback-only for a second reason besides the key: it makes the host issue a GET to a caller-chosen URL and reports the outcome, which is a probe an anonymous LAN caller must not have. Every refusal folds into `model-discovery-failed`, whose message is the adapter's own text and whose details name the endpoint asked but never the credential offered. + +`dsh-llm-pi-ai` implements the wire path as a plain `GET {baseURL}/models`, reading `openai-completions` and `openai-responses`: their `GET /models` shape with bearer auth is the one a gateway, a self-hosted server, and the official endpoints all agree on. Azure is excluded despite its OpenAI lineage — it authenticates with an `api-key` header and requires an `api-version` query — and Codex uses OAuth; both would have reported an authentication failure as a provider with no models. Every other protocol answers `DISCOVERY_UNSUPPORTED`, so the surface falls back to hand-entry rather than reporting a guessed response shape as an empty provider. `baseURL` is treated as a prefix rather than a URL to resolve against, so a deployment path such as `https://gateway.example/openai/v1` keeps its segments. The reply is read under a four-megabyte ceiling enforced on the bytes actually received — the endpoint is a URL the user typed, so a declared `content-length` is checked first as a courtesy but never trusted as the bound, matching `dsh-web-fetch`'s two-stage shape for its own caller-supplied URLs. + +### Why not pi-ai's own refresh machinery + +pi-ai supplies `createProvider({ fetchModels })` plus `Models.refresh()` and a `ModelsStore`, and the layer below already builds pi-ai `Provider` objects. Routing interrogation through them would have meant constructing a throwaway provider and collection per question, with a store whose entire purpose — persisting a catalog across runs — contradicts the decision that `settings.yaml` owns the catalog. It would also have bought nothing: **no built-in pi-ai provider implements `fetchModels`**, so the HTTP call and its response parsing are this package's code either way. A direct fetch says what is actually happening. The route's stored credential is resolved by the plugin's own per-request resolver, and only on the branch that reaches the network, so a catalog route answers without touching credentials and never fails over one the question did not need. + +## Alternatives considered + +**Key interrogation by provider route.** Symmetric with every other seam operation, and it would let the request omit the endpoint. But the case that motivates the feature — adding a provider — has no route, so the operation would only work for providers already configured, which are the ones that need it least. + +**Put the capability on `LlmAdapter`.** Adapters are reached through a route registration, so this has the same problem, plus it would make an adapter instance answer questions about endpoints it does not serve. + +**Have the host read the stored profile instead of accepting a draft.** No secret would cross the wire for an already-configured provider. But adding a provider would then require saving an unusable configuration first, and a form whose endpoint was edited but not yet saved would silently interrogate the old one. Accepting the draft keeps what the user sees and what is asked identical — with the credential as the one exception, because it is the one field a surface is never shown and so can never put in the draft. + +**Interrogate every pi-ai protocol.** Anthropic's listing happens to share OpenAI's envelope, and Google's does not. Supporting the ones that are easy would make coverage arbitrary and, worse, make a wrong guess at a response shape indistinguishable from a provider with no models. A protocol that says it cannot be interrogated sends the user to hand-entry, which is the documented fallback. + +**Buffer the reply with `response.text()` and check its length.** Simpler, but the bound would arrive after the bytes did, and the endpoint is whatever URL the user typed. + +## Consequences + +A person adding a gateway can ask it what it serves instead of hunting through its documentation, and the answer arrives as candidates they choose from rather than as configuration written behind their back. The seam gained a registry that is deliberately small: one offer per namespace, no storage, no lifecycle beyond the fiber. + +What it costs: the wire gained a third secret-carrying payload, so the configuration plane's write-only surface is now three methods rather than two. Discovery coverage is protocol-shaped rather than provider-shaped — an Anthropic-compatible gateway must be filled in by hand even though its listing would parse. And because nothing re-runs the question, a model list is still only as current as its last edit; that is the same trade the layer below made deliberately. + +## Testing + +`packages/llm/llm/tests/topology.spec.ts` covers the registry: one offer per namespace, disposal with the fiber, normalization that drops duplicate and unusable ids without inventing capacities, and the `NO_DISCOVERY`/`INVALID_DISCOVERY` refusals. `packages/llm/llm-pi-ai/tests/discovery.spec.ts` drives the probe against local HTTP servers — a listing with and without disclosed capacities, a preserved deployment path, an absent credential, a configured route supplying its own where the draft has none and a typed key winning over it, a catalog route answering without resolving one at all, dropped rows, 401/403 versus a server fault, a non-listing and a non-JSON body, an unreachable endpoint, caller cancellation, an unsupported protocol, and the size ceiling in both its declared-length and streamed forms. `packages/host/apiproxy/tests/api-proxy-config.spec.ts` covers the RPC over a real proxy: the draft reaching its namespace whole, absent fields staying absent, no namespace or credential being written, and a failure surfacing as `model-discovery-failed` with the credential absent from the serialized error. diff --git

让适配器插件为自己拥有的 namespace 提供「询问端点」的能力，`ctx.llm.discoverModels(settingsNs, request)` 发起询问。没有任何办法枚举哪些 namespace 注册过：询问不了的界面会从那句拒绝里知道，而一份无人消费的列表只会变成一个什么都不做的必填协议字段。以 namespace 为键是对的，因为配置界面已经从可配置提供方目录里拿到了它，也因为正在新增的提供方没有路由可点名。 +- `LlmModelDiscoveryRequest` 携带草稿——可选的 `provider`、可选的 `baseURL`、可选的 `api`、可选的 `apiKey`，以及一个 signal——且 `provider` 与 `baseURL` 至少要有一个，才有东西可答。`provider` 之所以存在，是因为适配器已经描述过的路由直接由它自己的注册表作答、完全不联网；只有它未描述的路由才会抵达某个端点。这条路径不写 settings 与 credentials。唯一的读取是请求所点名路由的凭据：配置界面拿到的是脱敏描述符而非已存的机密，因此草稿里的 `apiKey` 只在用户正键入时才存在；没有这次读取，已配置好的路由就会被不带认证地询问，只换回一个 401。键入的密钥优先，因为那正是被测试的那一把。 +- `LlmDiscoveredModel` 除 `id` 外每个字段都可选，因为大多数列表只公布 id。回复是候选而非 catalog：采纳其中一条的界面仍要补上适配器所需的容量。 +- `llm.discoverModels` 把同一份草稿送过协议层。它的 `apiKey` 是 secret 可以搭乘的第三个、也是最后一个载荷（另两个是

LAN 调用者不该拥有的探测能力。每一种拒绝都折叠为 `model-discovery-failed`，其消息是适配器自己的文本，details 点名被询问的端点，绝不点名所提供的凭据。 + +`dsh-llm-pi-ai` 的实现只是一次朴素的 `GET {baseURL}/models`，且仅限 OpenAI 兼容协议。它们的列表形状是网关、自建服务与官方端点三方一致认可的那一种，而这正是该动作存在的场景。其余协议一律以 `DISCOVERY_UNSUPPORTED` 回答，让界面回退到手工填写，而不是把猜错的响应形状报成一个空提供方。`baseURL` 按前缀而非待解析 URL 处理，因此 `https://gateway.example/openai/v1` 这类部署路径会保留其路径段。回复在四兆字节上限下读取，且上限落在实际收到的字节上——端点是用户自己填的 URL，因此会先看声明的 `content-length` 作为善意提示，但绝不把它当作边界；这与 `dsh-web-fetch` 面对自己的调用方提供 URL 时所用的两段式形状一致。 + +### 为什么不用 pi-ai 自己的 refresh 机制 + +pi-ai 提供了 `createProvider({ fetchModels })` 加上 `Models.refresh()` 与 `ModelsStore`，而下层本来就在构造 pi-ai `Provider` 对象。把询问接到它们上面，意味着每问一次就要构造一个用完即弃的 provider 与集合，而那个 store 的全部目的——跨运行持久化 catalog——恰恰与「`settings.yaml` 拥有 catalog」的决定相抵触。而且它什么也换不来：**没有任何一个 pi-ai 内置 provider 实现了 `fetchModels`**，因此 HTTP 调用及其响应解析无论如何都是本包的代码。直接 fetch 才如实说出正在发生的事。路由已存的凭据由本插件自己那套逐请求解析器取出，且只在真正要联网的那条分支上进行，因此 catalog 路由作答时既不触碰凭据，也不会因为一把这次询问根本用不上的密钥而失败。 + +## Alternatives considered + +**以提供方路由为键。** 与其他每个 seam 操作对称，也能让请求省去端点。但催生该功能的场景——新增提供方——没有路由，于是这个操作只对已配置好的提供方可用，而它们恰恰最不需要它。 + +**把能力挂在 `LlmAdapter` 上。** 适配器要经由路由注册才能抵达，因此问题相同；而且这会让一个适配器实例去回答它并不服务的端点的问题。 + +**让 host 读已存 profile，而不是接受草稿。** 对已配置好的提供方来说，不会有 secret 跨越协议层。但这样一来新增提供方就必须先保存一份不可用的配置，而端点已改却尚未保存的表单会静默地去询问旧地址。接受草稿让用户看见的与被询问的保持一致——凭据是唯一的例外，因为它是界面从不被展示、因而永远无法放进草稿的那个字段。 + +**询问 pi-ai 的每一种协议。** Anthropic 的列表恰好与 OpenAI 共用同一层信封，而 Google 的不是。只支持容易的那几种会让覆盖范围变得任意；更糟的是，猜错的响应形状会与「该提供方没有模型」无法区分。一个明说自己无法被询问的协议，会把用户送去手工填写——那正是既定的回退路径。 + +**用 `response.text()` 缓冲整个回复再判断长度。** 更简单，但上限会在字节已经到达之后才生效，而端点是用户随手填的任意 URL。 + +## Consequences +

Large JSONL artifacts made that one-time operation pay several avoidable costs: each independent Zstandard frame created and closed a decoder context, decoded plaintext was accumulated and rescanned as whole-log buffers and strings, and freshly parsed events went through generic snapshot and deep-freeze paths designed for borrowed or cyclic values. + +A representative profile contained 61.8 MiB of Zstandard data, 97.1 MiB of plaintext, and 1,307,073 events. The restore path must reduce its CPU and memory cost without weakening checksum validation, committed-region corruption detection, torn-tail recovery, sequence and surface validation, or the session log's immutability. + +## Decision + +Restoration is one ownership-transfer pipeline from the persistence artifact into `Session.fromRestore`. The compressed artifact remains the source buffer, while each decoding and scanning stage consumes the previous stage's output incrementally without retaining a whole-log plaintext or parsed copy; the resulting event array is the only complete decoded representation. + +### Frame decoding + +The structural Zstandard scanner identifies complete frame ranges before decoding. The dedicated first frame is decoded and parsed separately as the session header; subsequent plaintext frames are yielded in order into the JSONL scanner. + +`ZstdFrameDecoder` gives the reader one lifecycle for interchangeable synchronous implementations. The preferred implementation probes the supported Node 22, 24, and 26 stream shape, reuses one private native decoder context and scratch buffer across all complete frames, and closes it once. If that private shape is unavailable, the factory selects a public `zstdDecompressSync` implementation with the same iterator and checksum-error contract. A yielded scratch view is consumed before the iterator advances. + +After approximately 500 ms of accumulated frame work, the asynchronous reader yields at the next frame boundary and observes cancellation before continuing. A single frame remains an indivisible synchronous operation. Complete frames require end-of-frame and checksum validation; only a structurally incomplete final frame uses the existing prefix decoder for recovery. + +### Incremental JSONL scanning + +`SessionLogScanner` searches raw buffers with `Buffer.indexOf(0x0A)` and converts only complete records to UTF-8 for `JSON.parse`. It carries an incomplete record across decoder writes and copies only that fragment because the private decoder may reuse its output buffer. It does not build a whole plaintext buffer or string, a line array, or a second parsed-record array. + +The scanner stops retaining events at the first unparsable row or sequence gap but continues inspecting later complete records. A later `turn/end` proves that the issue lies in the committed region and rejects the log. The Zstandard reader also rejects any unresolved parse, sequence, or partial-record issue after all complete frames; only a structurally torn final frame may contribute a recoverable suffix. Complete records emitted from that torn frame pass through the same scanner and retain the existing repair offset and recovered-event semantics. + +### Restore admission + +Persistence transfers freshly materialized JSON values to `Session.fromRestore`. These values are detached, acyclic trees, and packed chunk rows expand into newly allocated events, so the restore-only path validates the fixed event envelope with one `for...in` and `switch`, dispatches current-shape checks by event discriminant, and iteratively freezes the owned graph with an explicit `pending` array and no cycle-tracking set. Surface validation records one transition plan and commits that plan when the exact candidate enters the log instead of planning the same event twice. + +Borrowed seeds used by ordinary creation and fork paths still take a JSON snapshot and use the generic cycle-safe deep freeze. The specialization therefore changes only durable restoration; it does not weaken acceptance for caller-owned values. + +## Alternatives considered + +- **One asynchronous native operation per frame** — rejected because dispatch and callback overhead dominates logs containing many small durable batches. Cooperative synchronous decoding pays that overhead only at periodic yield boundaries. +- **Process the complete log synchronously without yielding** — rejected because it prevents cancellation and event-loop progress for the full restore duration. Frame-boundary yields retain a bounded observation point without splitting codec operations. +- **Concatenate all plaintext before scanning** — rejected because it retains the compressed input, complete plaintext, whole-log UTF-8 string, line metadata, and parsed rows at the same time, and it rescans a torn-frame prefix. +- **Implement a streaming JSON parser** — rejected because JSONL already provides record boundaries; native newline search plus `JSON.parse` removes the large intermediates without owning another parser or changing JSON semantics. +- **Use a shared `WeakSet` while freezing restored events** — rejected because JSON materialization cannot produce cycles, and the set adds a lookup per object while retaining the complete graph during traversal. +- **Skip validation or freezing for restored values** — rejected because durable storage is a runtime boundary and `Session.events` promises immutable accepted history. The optimized path specializes those operations around stronger ownership facts instead of removing them. + +## Consequences + +On the representative profile, incremental scanning reduced JSONL scan time from about 598 ms to 397 ms and peak RSS from about 1,494 MiB to 1,060 MiB. Restore admission reduced `Session.fromRestore` from 604–608 ms to about 263 ms, including an `assertSessionEventEnvelope` reduction from about 77 ms to 13 ms. These measurements characterize the optimization input rather than establish runtime limits. + +The fast decoder depends on runtime-probed Node internals, but incompatibility selects the public implementation rather than changing correctness.

Cordis service injection cannot express this dependency: a service is only an indirect ordering signal, client manifest dependency rows do not sequence activation, and a slot can disappear and return while every related service remains mounted. Registering immediately therefore races an undeclared slot, while waiting on an unrelated service couples independently reloadable features. + +Slot-level hot replacement also requires two independent owners.

A replacement declaration with the same key is a new lifetime even when disappearance and reappearance batch into one notification. + +## Decision + +`SlotsService.inject(name, callback)` makes the declared slot itself the dependency. The full `SlotMap` key is statically checked; there is no namespace builder, synthetic Cordis service, or slot-specific `Context`. The callback runs immediately when the declaration exists, otherwise waits, and returns either one synchronous disposer or a synchronous iterable of disposers. Iterable effects install transactionally: a later setup failure disposes every earlier yielded effect in reverse order. + +The ledger records a declaration epoch distinct from the slot's ordinary entry version. An epoch changes whenever a child declaration is created or collapsed. Injection remembers the active epoch, disposes its callback effect when that epoch ends, and reruns the callback for a replacement declaration even when the final observed state is continuously declared. Ordinary contribution changes do not restart injection. + +Both sides retain their natural ownership. The injection controller and every contribution run on the contributing plugin's caller `Context`, so disposing that plugin removes its wait and active entries. The slot ledger's existing child-collapse cascade removes entries when the declarer disappears; injection then runs their disposers to release service-layer resources and remains ready for a later declaration. The declaring plugin's `Context` is neither retained as a capability source nor exposed to contributors. + +Dynamic reload code uses an ordinary Cordis plugin fiber as its replacement unit: activate the new module through `ctx.plugin()`, dispose and await the old fiber before mounting its replacement, and let its `slots.inject` and `slots.register` effects leave with that fiber. Renderer subscriptions observe the ledger removal and unmount the component; no slot-owned fiber tree is required. + +## Failure and lifecycle contract + +An injection whose declaration already exists reports callback setup failures synchronously. A callback failure after a delayed declaration first unsubscribes and rolls back its collected effects, then reports the failure outside the slot notification flush so one registrant cannot starve other listeners. Direct `slots.register()` into an undeclared slot continues to throw: injection is explicit and does not weaken load-time validation. + +Disposing an injection is idempotent. It unsubscribes before releasing the active callback effect, preventing teardown-triggered ledger notifications from resurrecting the contribution. Declaration-bound teardown is synchronous with the ledger boundary, so it releases service-layer resources before any subsequent same-tick registration. A waiting injection disposed with its plugin cannot activate later. + +## Alternatives considered + +**Use `ConversationService` or another service as an ordering barrier.** Service presence does not identify the declaration or follow its reload lifetime, and it creates a false package dependency for presentation-only contributors. + +**Bridge each declaration into a `slot:` Cordis service.** This pollutes the service namespace, turns a misspelled dynamic key into a silent service wait, and disguises ledger state as a business capability. Native slot injection provides the same wait without changing Cordis topology. + +**Create a Cordis context or fiber for every slot.** A contributor needs the intersection of its own plugin lifetime and the declaration lifetime, not the declarer's capabilities. A slot-owned context introduces capability inheritance and dual-parent teardown problems without improving ledger ownership. + +**Make `register()` wait implicitly.** Immediate failure on an undeclared target is a valuable configuration check.

This note takes the third. "Values landed with the query index" was once this note's settled direction and was under construction for a time, then retired wholesale: query infrastructure was forced to learn domain vocabulary while the sole consumer is satisfied by read-time computation — the live child's zero reads come for free from session-projection's existing watermark cache, and the cold child's single full read is explicitly accepted as compute-and-discard. The first two routes and the retirement rationale are detailed under Alternatives considered. + +Key points: + +- **The subagent list does not depend on session-query**: enumeration is completed by a subagent-owned live-preferred merge, and mode/label is retrieved through `ctx.sessionProjections`; deployments without a query backend list as usual. +- **Value retrieval is a three-rung compute-and-discard ladder**: a live child reads `sessionProjections.snapshot()` (the registry's existing watermark cache, zero log reads); a cold child first reads the optional `sessionProjectionCache.cachedSnapshot(header)`, using the value directly when a non-null `subagent` identity passing the seq gate (`seq >= seedLength ?? 0`) is among its values; otherwise it pays one full `persistence.inspect` read plus one `registry.restore({}, events, 0)` fold; beyond that, absent is absent — no cache of its own, no write-back, no index. +- **The `subagent` projection unit is the sole authority over the fold rules**: the live snapshot, the cold restore, and GUI history's detached fold all compute through the registry; no second copy of descriptor-interpretation logic exists. +- **The header, the descriptor (v2), session-persistence, session-projection(-cache), and session-query(-sqlite) are all untouched**; pre-existing data acquires exact values through one `inspect` computation the first time it is listed — no degraded unknown state, no migration. + +Relationship to existing notes: + +- This note supersedes two designs on the list read path in [durable-subagent-catalog](../feature/2026-07-22-durable-subagent-catalog-and-list-agents.md): enumeration through `sessionQuery.traceSession`, and per-child descriptor-event reads (the `listEvents`-plus-exact-`readEvent` double read with in-place diagnostic classification). The diagnostic row semantics is retained, with classification now derived by the list from projection-value absence and activity; the descriptor event remains the sole durable authority for mode/label and the fold input, and the resume authorization and Activation contracts are untouched. This is partial supersession; the two notes stay cross-linked. +- The [session-projection RFC](../../proposed/architecture/2026-07-27-session-projection-and-command-log.md)'s registry contract (`ProjectionDefinition`, `snapshot`, `restore`) is untouched; this note only adds one registration to it — the `subagent` identity unit — and becomes another consumer instance of the two existing reads, snapshot (live) and restore (cold) — GUI history's cold read is already the same shape. The fold rules are registered with the registry exactly once; every consuming surface computes through the registry, and no second copy of the fold logic exists. + +### `subagent` projection unit + +It hangs beside the existing `subagentTiming` ([projection.ts](../../../../packages/subagent/subagent/src/projection.ts), [projection-types.ts](../../../../packages/subagent/subagent/src/projection-types.ts)), under key `subagent`: + +```ts ignore-check +export type SubagentIdentityProjection = + | { mode: 'one-shot'; label?: string; seq: number } + | { mode: 'continuable'; label: string; seq: number } + +declare module '@deepseek-ai/dsh-session-projection/types' { + interface SessionProjectionMap { + subagent: SubagentIdentityProjection | null + } +} +``` + +- The projection is pure identity, and **the projection system has no failure channel**: a unit never throws; a corrupt payload or an unrecognized version folds exactly like a log with no descriptor at all — the result is a **serializable null sentinel**: the map entry is `SubagentIdentityProjection | null`, non-optional, never undefined or an absent key. The reason: the registry's onChanged push goes through JSON serialization, where an undefined field is dropped by stringify, the client's frame validation rejects the frame, and a consumer's stored old identity would never update; null passes frames intact, and consumers replace the old identity with the sentinel. The judging discipline: consuming surfaces treat null and undefined (which only a JSON boundary dropping the key can produce) alike as no value. How "computed to nothing" is presented is the consumer's own business (see the `listChildren` four-state mapping below). +- Label strength is decided by the descriptor schema: a continuable's label is mandatory at parse, a one-shot's was always optional; the mode/label discriminant matches the child row's strong contract below exactly (the row carries no `seq` — it is the projection's internal own-suffix proof). +- The identity carries `seq`: the seq of the `subagent/descriptor` event it was folded from, mandatory on both arms and absent on the null sentinel — `seq >= header.seedLength ?? 0` proves the identity was folded from the child's own suffix rather than a fork seed's replayed ancestor descriptor. The state gaining `seq` bumps the unit's `stateVersion` to 2, and existing checkpoint rows are invalidated by version mismatch per the registry contract, falling to the authoritative refold. +- Fold rule: `subagent/descriptor` is last-wins, under the same descriptor-reset discipline as `subagentTiming` — ancestor descriptors in the fork prefix are overridden by the session's own descriptor. A corrupt or unrecognized-version payload is last-wins all the same: it resets to the null sentinel rather than keeping the prior identity, so a fork of a healthy ancestor does not inherit an identity its own descriptor cannot stand up. + +### Enumeration: subagent-owned live-preferred merge + +`listChildren`'s ([list-children.ts](../../../../packages/subagent/subagent/src/list-children.ts)) enumeration goes through no query service: the two sources `ctx.sessions.list()` and `ctx.get('sessionPersistence')?.list()` merge by id, with a live record overriding the same-id persisted record wholesale and no header consistency check. Everything enumeration needs is header facts: + +- Filtering: `header.origin === 'subagent' && header.parentSession === parentSessionId`. +- `hasChildren`: the same merged material, looked at one level down — a direct descendant exists with `origin === 'subagent'` whose `parentSession` is that child. +- `activity`: a live record is `running`; one present only in persistence is `inactive`. +- Ordering: `createdAt` ascending, then child id ascending (matching the old contract). +- **Absent persistence degrades to live-only enumeration, not an error**: in a deployment without persistence, a cold child could not be resumed anyway, and listing live children remains meaningful. (Contrast: the old implementation rejected wholesale when sessionQuery was missing.) +- A persistence listing failure fails the whole enumeration; per-child isolation applies only to the per-child cold reads. + +### Value retrieval: the three-rung compute-and-discard ladder + +For each enumerated child, mode/label retrieval walks a three-rung ladder — compute-and-discard, no cache of its own, no write-back (the third rung is the same shape as apiproxy `session.history`'s cold read): + +| Rung | Read | Cost | +| --- | --- | --- | +| 1: live child | `ctx.sessionProjections.snapshot(session).values.subagent` | Zero log reads — the registry's existing watermark cache, synchronous retrieval | +| 2: cold child, cache hit | The optional `sessionProjectionCache.cachedSnapshot(header)`, used directly only when a non-null `subagent` identity satisfies `identity.seq >= header.seedLength ?? 0` — an own descriptor is immutable once appended, and the seq gate proves the value was folded from the child's own suffix, regardless of the row's watermark | Zero log reads | +| 3: cold child, fallback | One full `persistence.inspect(id)` read + `registry.restore({}, events, 0).snapshot.values.subagent` | One full read computed per listing | + +- Error contract: an unmounted `ctx.sessionProjections` is a configuration error; `listChildren` checks unconditionally before enumerating and fails loudly with `SUBAGENT_CONTROL_PROJECTIONS_UNAVAILABLE` — a deployment with zero children fails just as deterministically, so an empty listing cannot mask the misconfiguration. The session store gets the same posture: an absent `ctx.get('sessions')` (a strict global read, never the caller-scope-bound property proxy) fails with `SUBAGENT_CONTROL_SESSION_STORE_UNAVAILABLE`. The two codes map differently on the wire: apiproxy gives only `PROJECTIONS_UNAVAILABLE` a dedicated wire face, and `SESSION_STORE_UNAVAILABLE` goes through the generic internal fallback — the apiproxy composition injects `sessions` itself, so that error is unreachable in its deployment, and a dedicated mapping would violate the need principle. `SUBAGENT_CONTROL_SESSION_QUERY_UNAVAILABLE` is deleted along with the session-query dependency. +- The cache is a purely optional acceleration layer: an absent service is skipped on a null check — no error code, no part in configuration validation (in contrast to `sessionProjections`' loud contract). Anything the second rung throws (including a poisoned unit row in the cache detonating `viewCheckpoint`) silently falls to the third rung — the cache is derived data, so its faults never produce a `corrupt` verdict; the final judgment belongs to the authoritative refold. A row whose checkpoint cut predates the descriptor naturally lacks the `subagent` key and falls through automatically, with no special-casing; a null sentinel in the row does not count either — it falls to the third rung for the authoritative refold's verdict. A count/interval checkpoint inside the creation window can land a fork seed's replayed ancestor identity in the row — the ancestor's seq falls inside the seed range, the seq gate rejects it, and it likewise falls to the third rung's verdict. +- Per-child isolation: a single child's failed cold full read only turns that row into an `unavailable` diagnostic, naturally retried on the next listing, without affecting siblings (see the four-state mapping). +- The cold path's lifecycle witness: preparation's result must still point at the lifecycle that was enumerated — the witness field set is the same seven fields as the old SOURCE_CONFLICT check (version, id, createdAt, cwd, parentSession, seedLength, delegationDepth); a session deleted and republished under the same id degrades to a `corrupt` row in the old parent's catalog, leaking nothing of the new owner's child. +- Cold-read concurrency is bounded by the constant 4 — it constrains a read-only scan of local media, not deployment behavior; when a networked persistence backend appears, it is promoted to a validated `Config` field. +- The cold-read cost, recorded honestly: only with the cache unmounted or missed does a cold child pay one full read per listing, at a cost proportional to its transcript size; the settled stance is compute-and-discard, and no cache of its own is built. The full read goes through `inspect()` into the [Session preparation](2026-08-05-session-preparation.md) cold read, so short-term repeated reads of the same id can hit its LRU for reuse, but listing does not depend on this. A live child reads zero log throughout. +- Cancellation: the caller's signal is checked before and after each persistence read, and a read that settles only after abort is rejected, normalized to the stable error code `CANCELLED`. + +### Authority model + +- The session log is the sole authority; this design adds no derived persistence of any kind — no index values, no checkpoints of its own, no in-process memo; the `sessionProjectionCache` checkpoint the second rung reads is an existing composition item's derived data, which this design only reads and never writes. Values are computed on read and discarded, and a value's freshness is exactly the live state or persisted revision at the moment of the read (an own descriptor is immutable once appended — a cached identity past the seq gate has no staleness problem; the gate guards against seed-replayed ancestor identities). +- The Session and persistence write paths are entirely unaware of listing and projection consumption: no event-listener write-back, no fold-on-write. +- Enumeration and value retrieval constitute no second authorization source and make no unpublished child visible — the two sources see only published live records and durably written persisted records, consistent with the rule the durable-subagent-catalog note laid down for derived read surfaces. + +### `listChildren` row shape and consuming surfaces + +The `SubagentListEntry` **data structure is identical to before the rewrite** — the child and diagnostic arms, the `kind` discriminant, the three-valued `reason`, and the child arm's strong mode/label contract are all retained; the only change is the diagnostics' information source: the projection system has no failure channel, so diagnostics are derived by the list from projection-value absence and activity, and the list itself parses zero events. The "no value means await the hard read" rule guarantees the ladder always computes mode/label for healthy data. + +```ts ignore-check +export type SubagentListEntry = + | ({ + readonly kind: 'child' + readonly id: SessionId + readonly activity: 'running' | 'inactive' + readonly hasChildren: boolean + } & ( + | { readonly mode: 'one-shot'; readonly label?: string } + | { readonly mode: 'continuable'; readonly label: string } + )) + | { + readonly kind: 'diagnostic' + readonly id: SessionId + readonly reason: 'corrupt' | 'unsupported' | 'unavailable' + } +``` + +For each enumerated child, the ladder's result maps to a row through four states: + +| Ladder result | Row | +| --- | --- | +| Snapshot carries a non-null `subagent` identity | child row | +| Snapshot present, `subagent` null sentinel or key absent, and the child is **inactive** | diagnostic row, reason `corrupt` (settled debris: a missing, corrupt, or unrecognized-version descriptor, no longer subdivided) | +| Snapshot present, `subagent` null sentinel or key absent, and the child is **running** | no row (creation window: the descriptor is not yet appended — the same window the old implementation omitted) | +| The cold full read fails | diagnostic row, reason `unavailable` | + +- `unsupported` is no longer produced: the type and the wire enum retain the member under "data structures stay as they are", and this note records it as no longer produced. +- Descriptor-less settled debris moves from the old implementation's omit into the `corrupt` diagnostic — damaged, dead child sessions in the corpus are visible rather than silently vanishing, which is exactly the original motivation for keeping diagnostics. +- Any registered unit whose fold/schema throws on this child's log is likewise contained as that child's diagnostic row, reason `corrupt` — a deterministic data fault, aligned with the old implementation's `SESSION_QUERY_CORRUPT_SESSION`→`corrupt` mapping semantics; live and cold are treated alike, isolation is per-child, and siblings and the listing itself are unaffected. It is orthogonal to "value absent + running → omit": the creation window means "no data yet", a fold throw means "the data is bad" — a poisoned running child also gets a `corrupt` row rather than an omit. + +Known boundary deviations (deliberately accepted, recorded with this note): + +- A fork child that died in its publication window, with an ancestor descriptor in its seed, gets the ancestor identity from last-wins and wrongly surfaces as a child row; resume still fails against the own-suffix fold authority (`NOT_RESUMABLE`). The old implementation omitted it via `seedLength` filtering; the projection unit cannot see the header, and this debris-grade deviation is accepted (`subagentTiming` has the same kind of pre-existing exposure). +- Multiple descriptors in the own suffix: the old implementation judged corrupt; last-wins now takes the final one (the provider contract guarantees exactly one anyway). +- A live/persisted header conflict: the old implementation made it per-child corrupt; enumeration now prefers live with no consistency check, the conflict goes unnoticed, and the live record forms the row. +- A source-read failure on damaged storage (e.g. a bad surface rejected by the cold full read): the old implementation mapped it to per-child `corrupt`; it is now uniformly an `unavailable` row (the read side cannot tell the causes apart). +- An unknown parent: the old implementation threw not-found through session-query ('parent session … was not found'); the subagent-owned merge now yields an empty subset for a nonexistent parent, enumeration returns an empty list, and later operations on the wire land as child-level subagent-not-found — a silent change of semantics and wording, recorded as explicitly accepted. +- Rung 2's later-event window: a cache row lands right after the first own descriptor, the log then appends a second own descriptor (or a malformed payload setting the null sentinel), and the process crashes before the next checkpoint — from then on a cold listing's rung 2, admitted by the seq≥seedLength gate, keeps serving the row's old identity (the first own descriptor's value), diverging from the authoritative refold (last-wins, the second), and a rung-2 hit triggers no refold, so nothing notices. Three boundaries: ① the precondition is a second own descriptor on the same child, violating the establishing provider's append-exactly-once contract — corruption-class data, same family and source as the multi-descriptor deviation; ② it takes both "corruption + a crash missing every checkpoint (the two mandatory points, turn/end and disposal, and the count/interval throttle points all unmet)" at once; ③ a healthy child (exactly one own descriptor) is unaffected — what the seq gate admits is precisely the only true identity. Self-healing: any live run of that child (the turn/end mandatory checkpoint) or any moment that triggers cache.write overwrites the whole row with a fresh fold (whole-record replace), and rung 2 serves correctly from then on; the authoritative paths (the rung-3 refold, the live snapshot, the resume fold) are correct from the start, and the divergence exists only in listing reads while the child stays cold and the row is never rewritten. The mechanical fixes were not taken: gate reconciliation would need the log-end seq, unavailable to a zero-read cold path; a cache row carrying the revision is an opaque token, incomparable and a cross-domain schema change — filed as accepted under the "the cache is never authoritative" doctrine. + +Consuming surfaces: diagnostic handling across wire, tool, and GUI **stays entirely as it was, zero changes** (the `list_agents` description and output schema are untouched; the plugin only narrows its load requirement — `sessionQuery` dropped from inject). The only behavioral changes are in apiproxy: on the route segment, the `hasSubagentDescriptor()` scan is deleted and `hasSubagentOwner` looks only at `header.origin` — pre-#1569 data without `origin` is no longer recognized as a subagent owner; it never entered the catalog anyway, and the pre-release stance accepts this; and `subagents.history` is aligned with `session.history`'s source — a live child served from in-memory events and the registry's watermark snapshot, a cold child from `inspectServable` reading persistence directly with a detached fold, no query service involved, the SESSION_QUERY_* error arms retired with it, and the wire shape unchanged (the `history` JSDoc wording becomes the live in-memory snapshot / cold persisted log dual arm). + +### Change footprint + +| Area | Files | Change | +| --- | --- | --- | +| subagent | projection.ts, projection-types.ts, index.ts | New `subagent` unit and its registration | +| subagent | list-children.ts and its types | Rewritten as subagent-owned enumeration plus the projection-ladder four-state mapping; the session-query dependency, per-child event reads, and in-place classification machinery deleted; error code `SUBAGENT_CONTROL_SESSION_QUERY_UNAVAILABLE` replaced by `SUBAGENT_CONTROL_PROJECTIONS_UNAVAILABLE`; new optional dependency dsh-session-projection-cache (pure read acceleration, skipped when absent) | +| host/apiproxy | api-proxy.ts | `hasSubagentDescriptor` deleted; the owner check looks only at `header.origin`; `subagents.history` shares `session.history`'s source — live from in-memory events and the registry's watermark snapshot, cold from `inspectServable` reading persistence directly with a detached fold, no query service, the SESSION_QUERY_* error arms retired with it | +| tool | tool-subagent-control/list-agents.ts | Load requirement narrowed (`sessionQuery` dropped from inject); model-visible schema, description, and rendering unchanged | +| wire/client | api/subagents.ts, runtime sessions/service.ts, GUI | Types, row shape, and diagnostic handling **unchanged**; api/subagents.ts only reworded the `history` JSDoc to the dual arm | +| core/session, session-persistence, session-projection(-cache), session-query(-sqlite) | — | **Zero changes** | + +## Alternatives considered + +**mode/label into SessionHeader.** The strongest zero-read guarantee — rows form from the header alone. But a header shape change propagates into both persistence backends and the header compatibility check; SQLite rejects pre-existing data outright, and JSONL pre-existing data can only degrade to unknown or be backfilled. Read-time computation's answer for pre-existing data is "one `inspect` computation on first listing", touching no durable format. + +**The projection-cache ladder (v3 draft: `cachedSnapshot ?? coldSnapshot` plus fail-soft write-back).** The mechanism works — session-projection-cache's checkpoint ladder is designed for cold reads in the first place. But checkpoint write-back is a whole list-driven body of derived-data persistence and invalidation orchestration (floor/identity/putSoft); what was rejected is that orchestration as the primary mechanism. The settled three-rung ladder later reuses this cache opportunistically, read-only, as its second rung — no write-back, no orchestration, skipped when absent. + +**A bounded-read primitive on persistence to rescue pre-existing data.** Opens a new seam primitive for a one-time problem; superseded by the read-time `inspect` full read — the full read the first time pre-existing data is listed is itself the value retrieval. + +**Optional mode/label on list rows (one v4 draft).** Healthy data is always computable; optionality merely spills garbage-data handling complexity onto every consumer — each consuming surface has to grow filter branches and an unknown display state. The strong contract plus omit-when-uncomputable is cleaner. + +**Deleting diagnostic rows outright (one v5 draft).** Deletion turns corpus-corruption visibility into rows silently vanishing, and wire/tool/GUI would each have to absorb contract and snapshot changes; retention only asks the list side to derive the classification from projection-value absence and activity, at zero cost. That damaged, dead child sessions in the corpus must be visible is the original motivation for diagnostics' existence, and with retention the consuming surfaces stay wholly unchanged. + +**A registry computation failure channel (per-unit fault tolerance plus a supplementary `failures` field).** To report corruption and unrecognized versions to consumers, we once considered having the registry catch unit exceptions and attach a per-key failure state beside the snapshot. Rejected: a failure is not a value and needs no channel — a unit never throws, absence is itself the signal, worst case the computation comes back empty, and how that is presented is the consumer's problem. The discussion of this route left one independent observation behind: the vendored Cordis `emit` ([vendor/cordis/src/events.ts](../../../../vendor/cordis/src/events.ts)) catches nothing a listener throws, so with the projection driver hanging off `session/event`, a unit exception would escape along emit — which adds weight to the "a unit never throws" discipline, but fixing emit fault tolerance is outside this note's scope. + +**Values landed with query index preparation (the v4/v5 settled design, built for a time).** Projection values folded into session index rows during the sqlite backend's reconciliation rebuild, for zero log reads in the steady read state; the `projectionsFor` bulk read face, the invalidation reconciliation of row values stored against the `(key → stateVersion)` registration set, and the SCHEMA bump were all actually built. Retired wholesale: the direction was backwards — query infrastructure was forced to learn domain vocabulary (projection columns, registration-set reconciliation) while the sole consumer, the subagent list, is satisfied by read-time computation; with consumers down to zero, this derived persistence has no reason to exist. `SESSION_QUERY_PROJECTIONS_UNAVAILABLE` was deleted along with the read face. + +**Subagent hand-rolled parsing plus an in-process memo plus creation seeding (v6 draft).** To excise the session-query dependency, we once considered the subagent package parsing descriptor events itself, avoiding repeated full reads with an in-process memo, and seeding initial values at creation. Superseded by the v7 ladder: live goes through the `sessionProjections` watermark cache and cold through `registry.restore`, reusing the registry's single fold authority — no second copy of descriptor-interpretation logic appears, and no process-state cache or seeding ordering is introduced. + +**DeepReadonly on the session-query output surface (a read-path overhaul experiment).** Make the public query outputs deeply readonly to pin immutable borrowing at the type level. Rejected on evidence: 3 TS2589 occurrences (excessively deep type instantiation) plus 17 sites of array-position contagion (consumers' array methods and spread sites forced to follow); deep immutability is guaranteed by core/session's runtime deep freeze, and that read-path overhaul is not part of this note. + +## Verification + +`packages/subagent/subagent/tests/list-children.spec.ts` is rewritten to this contract: live-only listing without persistence, query services, or the continuation runtime; with the registry absent, even zero children loudly report `SUBAGENT_CONTROL_PROJECTIONS_UNAVAILABLE`; a live child incurs zero `inspect` throughout while a cold child incurs exactly one per listing; multiple descriptors resolve last-wins to the final one; corrupt payloads and unknown versions fold to `corrupt`; a cold-read failure maps to `unavailable` and retries on the next listing; the ancestor descriptor in a fork seed forms a row under that identity (pinning deviation one); ordinary forks and descendants without a subagent origin neither enter the list nor count toward `hasChildren`; `createdAt`-then-id ordering; an unmounted provider does not affect listing; compacted and uncompacted twins list identically; the three cases of pre-abort, persistence listing, and cold-read cancellation all normalize to `CANCELLED`; the empty list and stable error codes. A hostile-unit dual-path probe (`apply` lazily poisons, `view` detonates) proves that any registered unit's fold/schema throw on this child's log is contained as that child's `corrupt` row on both the live and the cold retrieval paths, with siblings and the listing itself unaffected. Second-rung cases: an own-seq identity used directly with zero `inspect`, a fork seed's ancestor identity (seq inside the seed range) rejected by the gate and falling through, an in-row identity absence (null sentinel or absent key) falling through, an absent cache service falling through, and a poisoned cache row silently falling through to the refold; cold-path lifecycle tampering degrades to `corrupt` field by witness field (`it.each` over the seven). The `tool-subagent-control` list-agents tests are updated for the narrowed load requirement; `optional-session-query.spec.ts` is deleted with the dependency it guarded; the existing keyless snapshots (`subagent-list-agents` among others) are unchanged, pinning that the healthy path's wire and model-visible surfaces did not move; a new keyless snapshot, `subagent-diagnostic` (examples/headless-agent), pins the four-state mapping's diagnostic classification — the model-visible changes such as descriptor-less settled debris becoming a `corrupt` row. + +## Consequences + +- Listing a live child reads zero log throughout; with the cache unmounted or missed, a cold child pays one full `inspect` read per listing, at a cost proportional to its transcript size and repeated with listing frequency — compute-and-discard is the settled stance: no cache of its own is built, nothing is written back, and short-term repeated full reads of the same id can hit the preparation-phase LRU, though listing does not depend on it. +- The subagent list no longer requires a query backend: both pure-live and persistence-less deployments can list; `SUBAGENT_CONTROL_SESSION_QUERY_UNAVAILABLE` is gone, and loading the `list_agents` plugin no longer requires `sessionQuery`. +- Identity interpretation exists only in the single unit registered with the registry: the list's three-rung ladder and GUI history's cold read all use the registry's and the cache's existing reads (snapshot, cachedSnapshot, restore), and no bypass fold exists; if some future consuming surface bypasses the registry with a hand-written fold, values will drift across read faces — a discipline this design requires be maintained, not a mechanical guarantee. +- Per-child isolation is back: a single child's cold-read failure loses only that row and healthy siblings are unaffected; a persistence listing failure still fails the whole enumeration. +- The diagnostic and enumeration semantics leaves six boundary deviations (a stillborn fork surfacing under its ancestor's identity, multiple descriptors resolving to the last, header conflicts going unnoticed, damaged-source read failures shifting from `corrupt` to `unavailable`, an unknown parent yielding an empty list instead of not-found, and rung 2's later-event window); the full semantics is in the known-boundary-deviations list; the first four are display or classification deviations on debris-grade data, the unknown-parent one is a silent query-semantics change, and the rung-2 window is a self-healing cache-serving divergence under the double condition of corruption plus a crash; resume authorization is unaffected throughout, all explicitly accepted. +- Pre-#1569 data without `origin` is no longer recognized as a subagent owner; it never entered the catalog anyway, and pre-release carries no compatibility promise. + +## Related + +- [Durable subagent catalog and list_agents](../feature/2026-07-22-durable-subagent-catalog-and-list-agents.md) — partially superseded by this note: the descriptor remains the durable authority for mode/label and the fold input,

走水位缓存，cold 一次整读）。本记录取第三条。"值随查询索引落库"曾是本记录的定稿方向并一度施工，最终整体退役：查询基础设施被迫认识领域词汇，而唯一消费方读时现算即可满足——live child 的零读由 session-projection 既有水位缓存白拿，cold child 的一次整读被"算完即止"显式接受。前两条与退役理由详见考虑过的替代方案一节。 + +要点： + +- **subagent 列表不依赖 session-query**：枚举由 subagent 自管的 live-preferred 合并完成，mode/label 经 `ctx.sessionProjections` 取值；没有 query backend 的部署照常列表。 +- **取值三级"算完即止"阶梯**：live child 读 `sessionProjections.snapshot()`（注册表既有水位缓存，零日志读）；cold child 先读可选 `sessionProjectionCache.cachedSnapshot(header)`，values 含非 null 且过 seq 门（`seq >= seedLength ?? 0`）的 `subagent` 身份即直接用；否则一次 `persistence.inspect` 整读加 `registry.restore({}, events, 0)` 折叠；再没有就没有——不自建缓存、无回写、无索引。 +- **`subagent` projection unit 是折叠规则唯一权威**：live snapshot、cold restore、GUI history 的 detached 折叠全部经 registry 计算，不存在第二份描述符解释逻辑。 +- **header、描述符（v2）、session-persistence、session-projection(-cache)、session-query(-sqlite) 全部零改动**；存量数据第一次被列表时一次 `inspect` 现算获得精确值，无 unknown 降级态、无迁移。 + +与既有记录的关系： + +- 本记录取代 [durable-subagent-catalog](../feature/2026-07-22-durable-subagent-catalog-and-list-agents.md) 中列表读路径的两项设计：经 `sessionQuery.traceSession` 枚举，与逐 child 读取描述符事件（`listEvents` 加精确 `readEvent` 双读、就地诊断分类）。diagnostic 行语义保留，分类改由列表按投影值缺席与 activity 派生；描述符事件仍是 mode/label 的唯一持久权威与折叠输入，恢复鉴权与激活契约不动。属部分取代，两记录保持交叉链接。 +- [session-projection RFC](../../proposed/architecture/2026-07-27-session-projection-and-command-log.md) 的 registry 契约（`ProjectionDefinition`、`snapshot`、`restore`）零改动，本记录只为其新增 `subagent` 身份 unit 一个注册项，并成为 snapshot（live）与 restore（cold）两处既有读法的又一消费实例——GUI history 的冷读已是同款。折叠规则只在 registry 注册一份；任何消费面都经 registry 计算，不存在第二份折叠逻辑。 + +### `subagent` projection unit + +挂在现有 `subagentTiming` 旁（[projection.ts](../../../../packages/subagent/subagent/src/projection.ts)、[projection-types.ts](../../../../packages/subagent/subagent/src/projection-types.ts)），key 为 `subagent`： + +```ts ignore-check +export type SubagentIdentityProjection = + | { mode: 'one-shot'; label?: string; seq: number } + | { mode: 'continuable'; label: string; seq: number } + +declare module '@deepseek-ai/dsh-session-projection/types' { + interface SessionProjectionMap { + subagent: SubagentIdentityProjection | null + } +} +``` + +- 投影是纯身份，**projection 体系不做失败通道**：unit 永不抛错；载荷损坏、版本不认识与整日志没有描述符一样，折叠结果是**可序列化的 null 哨兵**——map 条目为 `SubagentIdentityProjection | null`，非可选、非 undefined/缺 key。理由：registry 的 onChanged 推送经 JSON 序列化，undefined 字段被 stringify 丢弃，客户端帧校验拒收，消费方存储的旧身份将永不更新；null 完好过帧，消费方以哨兵替换旧身份。判定纪律：消费面把 null 与 undefined（仅 JSON 边界丢 key 可产生）一律视为无值。"算出来没有"如何呈现是消费方自己的事（见下文 `listChildren` 四态映射）。 +- label 强度由描述符 schema 决定：continuable 的 label 解析强制必有，one-shot 的本就可选；mode/label 判别与下文 child 行的强契约完全一致（行不携带 `seq`——它是投影内部的 own-suffix 证明）。 +- 身份携带 `seq`：折出该身份的 `subagent/descriptor` 事件 seq，两臂必有、null 哨兵无——`seq >= header.seedLength ?? 0` 证明身份折叠自 child 自身后缀，而非 fork 种子回放的祖先描述符。state 增 `seq` 使 unit `stateVersion` 升至 2，既存 checkpoint 行按 registry 契约版本失配失效、落权威重折。 +- 折叠规则：`subagent/descriptor` last-wins，与 `subagentTiming` 同一条 descriptor-reset 纪律——fork 前缀里的祖先描述符被自身描述符覆盖。损坏或版本不认识的载荷同样 last-wins：重置为 null 哨兵而非保留先前身份，健康祖先的 fork 不会继承自身描述符立不住的身份。 + +### 枚举：subagent 自管 live-preferred 合并 + +`listChildren`（[list-children.ts](../../../../packages/subagent/subagent/src/list-children.ts)）的枚举不经任何查询服务：`ctx.sessions.list()` 与 `ctx.get('sessionPersistence')?.list()` 两个来源按 id 合并，live 记录整条覆盖同 id 持久化记录、不做 header 一致性校验。枚举所需全部是 header 事实： + +- 过滤：`header.origin === 'subagent' && header.parentSession === parentSessionId`。 +- `hasChildren`：同一份合并材料向下看一层——存在 `origin === 'subagent'` 且 `parentSession` 为该 child 的直接后代。 +- `activity`：live 记录为 `running`，仅存在于持久化的为 `inactive`。 +- 排序：`createdAt` 升序、再按 child id 升序（与旧契约一致）。 +- **persistence 缺席退为 live-only 枚举，不报错**：没有 persistence 的部署，cold child 本就无法 resume，列出 live child 仍然有意义。（对照：旧实现在 sessionQuery 缺失时整体拒绝。） +- persistence 列表失败使整次枚举失败；per-child 隔离只作用于逐 child 的冷读。 + +### 取值：三级"算完即止"阶梯 + +对每个枚举出的 child，mode/label 取值走三级阶梯——算完即止，不自建缓存、无回写（第三级与

3：cold child，兜底 | `persistence.inspect(id)` 整读 + `registry.restore({}, events, 0).snapshot.values.subagent` | 每次列表一次整读现算 | + +- 错误契约：`ctx.sessionProjections` 未挂载是配置错误，`listChildren` 在枚举前无条件检查并以 `SUBAGENT_CONTROL_PROJECTIONS_UNAVAILABLE` 响亮失败——零 children 的部署同样确定失败，不因列表恰好为空而掩盖配置问题。会话存储同理：`ctx.get('sessions')`（严格全局读取，不走调用方作用域的属性代理）缺席以 `SUBAGENT_CONTROL_SESSION_STORE_UNAVAILABLE` 失败。两码的 wire 映射有别：apiproxy 只为 `PROJECTIONS_UNAVAILABLE` 设专门 wire 脸，`SESSION_STORE_UNAVAILABLE` 走通用 internal 兜底——apiproxy 组合自身就 inject `sessions`，该错误在其部署不可达，专门映射违反 need 原则。`SUBAGENT_CONTROL_SESSION_QUERY_UNAVAILABLE` 已随 session-query 依赖删除。 +- cache 是纯可选加速层：服务缺席判空跳过——无错误码、不进配置校验（与 `sessionProjections` 的响亮契约相对）。第二级任何抛错（包括缓存内任一 unit 行中毒使 `viewCheckpoint` 引爆）静默落第三级——缓存是派生数据，其故障不产生 `corrupt` 判决，终审归权威重折；checkpoint 切面早于描述符的行，`subagent` key 天然缺席，自动落底，无特判；行里的 null 哨兵同样不作数——一律落第三级，由权威重折裁决。创建窗口内的 count/interval checkpoint 可能把 fork 种子回放的祖先身份落进行——祖先 seq 落在 seed 区间，被 seq 门拒绝，同样落第三级裁决。 +- per-child 隔离：单 child 的 cold 整读失败只使该行成为 `unavailable` diagnostic，下次列表自然重试，不影响 sibling（见四态映射）。 +- 冷路径的生命周期见证：preparation 的结果必须仍指向枚举时的那个生命周期——见证字段集与旧 SOURCE_CONFLICT 检查同款七字段（version、id、createdAt、cwd、parentSession、seedLength、delegationDepth）；同 id 删除后重新发布的会话对旧 parent 的目录降级为 `corrupt` 行，不外漏新 owner 的 child。 +- 冷读并发以常数 4 有界——它约束的是本地介质的一次只读扫描而非部署行为；出现联网 persistence backend 时提升为验证过的 `Config` 字段。 +- 冷读成本如实记录：cache 未挂载或未命中时，cold child 每次列表才付一次整读，成本与其 transcript 大小成正比；定案"算完即止"，不自建缓存。整读经 `inspect()` 走 [Session 准备阶段](2026-08-05-session-preparation.md)的冷读，同 id 短期重复读取可命中其 LRU 复用，但列表不依赖此。live child 全程零日志读。 +- 取消：每次 persistence 读前后检查调用方 signal，abort 之后才结算的读拒绝归一化为稳定错误码 `CANCELLED`。 + +### 权威模型 + +- session log 是唯一权威；本方案不新增任何派生持久化——没有索引值、没有自己的 checkpoint、没有进程 memo；第二级读取的 `sessionProjectionCache` checkpoint 是既有组合项的派生数据，本方案只读不写。取值现算现弃，值的新鲜度就是读取时点的 live 状态或持久化 revision（own descriptor 一经追加不可变——缓存身份过 seq 门后无陈旧性问题，门防的是种子回放的祖先身份）。 +- Session 与 persistence 写路完全不感知列表与投影消费：没有事件监听回写，没有写时折叠。 +- 枚举与取值不构成第二个鉴权来源，也不让尚未发布的 child 可见——两个来源只见已发布的 live 记录与已落盘的持久化记录，与 durable-subagent-catalog 记录对派生读面立下的规则一致。 + +### `listChildren` 行形状与消费面 + +`SubagentListEntry` **数据结构与重写前完全一致**——child 与 diagnostic 两臂、`kind` 判别、reason 三值、child 臂的 mode/label 强契约全部保留；变化只在诊断的信息来源：投影体系没有失败通道，diagnostic 由列表按投影值缺席与 activity 派生，列表本身零事件解析。"没有就等待硬读取"保证阶梯对健康数据必然算得出 mode/label。 + +```ts

omit」正交：创建窗口是"尚无数据"，fold 抛错是"数据坏了"——running 的中毒 child 也出 `corrupt` 行而非 omit。 + +已知边界偏差（有意接受，随本记录留档）： + +- 死于发布窗口的 fork child，seed 里若有祖先描述符，last-wins 会给出祖先身份，误现为 child 行；恢复仍按 own-suffix 折叠权威失败（`NOT_RESUMABLE`）。旧实现靠 `seedLength` 过滤将其 omit；projection unit 看不到 header，接受此残骸级偏差（`subagentTiming` 有同类既有暴露）。 +- own suffix 出现多个描述符，旧实现判 corrupt，现 last-wins 取末者（provider 契约本就保证恰一）。 +- live/persisted header 冲突，旧实现是 per-child corrupt；现枚举 live 优先、不做一致性校验，冲突不再被察觉，以 live 记录成行。 +- 损坏存储的源读失败（如坏 surface 被冷读整读拒收），旧实现映射 per-child `corrupt`，现统一成 `unavailable` 行（读侧无从区分成因）。 +- 未知 parent，旧实现经 session-query 抛 not-found（'parent session … was not found'）；现自管合并对不存在的 parent 得到空子集，枚举返回空列表，wire 上后续操作落到 child 级 subagent-not-found——语义与文案的静默变化，显式接受。 +- rung 2 的更晚事件窗口：cache 行恰在首个自有描述符之后落盘，日志随后追加第二个自有描述符（或 malformed 载荷置 null 哨兵），且进程在下一次 checkpoint 前崩溃——此后冷列表的 rung 2 凭 seq≥seedLength 门持续供出行内旧身份（第一个自有描述符的值），与权威重折（last-wins 第二个）分歧，且 rung 2 命中期间不触发重折、无从察觉。边界三条：①前提是同一 child 出现第二个自有描述符，违反 establishing provider"恰追加一次"契约，属损坏类数据，与多描述符偏差同族同源；②需"损坏 + 崩溃错过 checkpoint（turn/end 与 disposal 两个 mandatory 点及 count/interval 节流点全部未及）"双条件同时成立；③健康 child（恰一自有描述符）不受影响——seq 门放行的正是唯一真身份。自愈条件：该 child 任一次 live 运行（turn/end mandatory checkpoint）或任何触发 cache.write 的时点，都会以新 fold 整行覆写（whole-record replace），rung 2 随即供正；权威路径（rung 3 重折、live snapshot、resume 折叠）自始正确，分歧只存在于持续冷、行未再更新期间的列表读。机制修法不采：gate 对账需知日志末端 seq，冷路径零读不可得；cache 行携 revision 是 opaque token，无法比较且跨域改 schema——按"cache 永不为权威"总纲归档为接受项。 + +消费面：wire、tool、GUI 的 diagnostic 处理**全部保持原状零改动**（`list_agents` 的 description 与 output schema 未动；该插件仅加载要求收窄——inject 去掉 `sessionQuery`）。行为上动的只有 apiproxy：路由段的 `hasSubagentDescriptor()` 扫描已删除，`hasSubagentOwner` 只看 `header.origin`——pre-#1569 的无 `origin` 存量不再被认作 subagent 属主，其本就不进目录，pre-release 立场接受；`subagents.history` 与 `session.history` 同源对齐——live child 用内存事件与注册表水位快照，cold child 用 `inspectServable` 直读持久化并

写回是一套由列表驱动的派生数据持久化与失效编排（floor/identity/putSoft）；被否的是这套编排作为主机制。定稿的第三级阶梯后来以只读方式机会性复用该缓存作第二级——无写回、无编排、缺席即跳过。 + +**给 persistence 加有界读原语抢救存量。** 为一次性问题新开 seam 原语；被读时 `inspect` 整读取代——存量第一次被列表时的整读就是取值本身。 +

反要各自承担契约与快照变更；而保留只需列表侧按投影值缺席与 activity 派生分类，零成本。库里的坏、死子会话必须可见是 diagnostic 存在的原始动机，保留后消费面整体零改动。 + +**registry 计算失败通道（per-unit 容错加 `failures` 附加字段）。** 为把损坏、版本不认识报告给消费方，曾考虑让 registry 捕获 unit 异常并在 snapshot 旁附 per-key 失败态。被否：failure 不是值，也不必是通道——unit 永不抛错，缺席本身就是信号，"大不了算出来没有"，如何呈现是消费方要考虑的事。该路线讨论顺带留下一个独立观察：vendor cordis 的 `emit`（[vendor/cordis/src/events.ts](../../../../vendor/cordis/src/events.ts)）对 listener 抛错零捕获，投影驱动挂在 `session/event` 上时 unit 异常会沿 emit 逃逸——这加重了"unit 永不抛错"纪律的分量，但 emit 容错的修复不属于本记录范围。 + +**值随 query 索引 preparation 落库（v4/v5 定稿，一度施工）。** 投影值在 sqlite backend 的对账重建里折叠落进 session 索引行，读稳态零日志；`projectionsFor` 批量读面、行值随 `(key → stateVersion)` 注册集存储的失效对账与 SCHEMA bump 均已施工过。整体退役：方向反了——查询基础设施被迫认识领域词汇（投影列、注册集对账），而唯一消费方 subagent 列表读时现算即可满足；消费方归零后，这套派生持久化没有存在理由。`SESSION_QUERY_PROJECTIONS_UNAVAILABLE` 随读面一并删除。 + +**subagent 手工 parse 加进程 memo 加创建播种（v6 稿）。** 为摘除 session-query 依赖，曾考虑 subagent 自己解析描述符事件、以进程内 memo 避免重复整读、创建时播种初值。被 v7 阶梯取代：live 走 `sessionProjections` 水位缓存、cold 走 `registry.restore`，复用 registry 这一份折叠权威，不再出现第二份描述符解释逻辑，也不引入进程态缓存与播种时序。 + +**session-query 输出面 DeepReadonly（读路径改造实验）。** 公开查询输出深只读化，以在类型层面钉死不可变借用。实证否决：3 处 TS2589（类型实例化过深）加 17 处数组位传染（消费方数组方法与展开处被迫跟改）；深层不可变由 core/session 的运行时深冻结保证，该读路径改造未纳入本记录。 + +## 验证 +

The existing mitigations (frame batching, the isolated streaming tail, the plain fence arm) bounded how often and how widely that work ran, never how much text each run re-parsed.

Each source region parses O(1) times per stream instead of once per chunk; a single giant block (an unclosed fence) degrades to the old full-reparse cost and no worse. Non-append input resets the state under a bumped generation. +- **Rendering** ([render.tsx](../../../../packages/client/ui-primitives/src/markdown/render.tsx), [katex.tsx](../../../../packages/client/ui-primitives/src/markdown/katex.tsx)): one switch over mdast node types replaces remark-rehype + react-markdown, reproducing the replaced pipeline's DOM byte-for-byte — table alignment as `text-align` styles, tight-list paragraph unwrapping, task-list classes and checkbox spacing, the footnote section (whose in-page anchors the protocol allowlist already reduced to plain text), literal raw HTML, the separator newlines that surface next to literal HTML text, and rehype-katex's three-arm error chain with KaTeX HTML mapped to React through the browser's own `DOMParser` (no wrapper element, so first/last-child margin rules still reach `.katex-display`; React 18 puts the `.katex-mathml` subtree in the HTML namespace exactly as the replaced pipeline did — a pre-existing limitation outside this parity contract, invisible to the visual `.katex-html` arm). Frozen blocks cache their React elements and keep source-offset keys, so crossing the freeze boundary reconciles instead of remounting; `MarkdownText` is memoized. + +The DOM is pinned by `tests/fixtures/markdown-dom`: fixtures recorded from the react-markdown implementation before the swap, which the new renderer must reproduce under a whitespace-normalizing serializer. A fixture diff is a user-visible markdown style change to review, never to re-record for a refactor. `tests/markdown-incremental.spec.tsx` holds the equivalence property — at every appended prefix, chunked at 1/3/7/16 bytes, the live component's DOM equals a fresh mount's — plus freeze-boundary DOM-node identity and reset behavior. + +This reverses the [assistant-markdown note](../feature/2026-07-23-web-assistant-markdown.md)'s rejected alternative ("maintain a custom React walker"): the incremental requirement is new evidence, the walker's security-sensitive branches (URL allowlist, image policy, inert HTML) were already product-owned functions, and the dependency no longer deleted owned code — it blocked the architecture. That note's untrusted-output policy and renderer selection are unchanged. + +## Alternatives considered + +**Keep react-markdown and split the source into per-segment `` instances.** Zero renderer ownership, but each frame parses the tail twice (boundary detection + render), settled math still re-parses everything, hast construction and the per-render processor remain, and blocks remount when crossing the freeze boundary because element trees cannot be cached across instances. + +**Render cached mdast through `mdast-util-to-hast` + `hast-util-to-jsx-runtime`.** Keeps upstream's node mappings for free, but retains the hast intermediate per frame and two new direct dependencies for a pipeline whose mapping surface is small, closed, and now pinned by fixtures. + +**Parse KaTeX output with `hast-util-from-html-isomorphic` (as rehype-katex does).** Pulls a parse5-based HTML parser into the bundle to parse trusted, vocabulary-constrained KaTeX output the browser's `DOMParser` (with the spec's SVG/MathML attribute adjustments) already parses identically. + +## Consequences + +Streaming per-chunk work now tracks the unstable tail instead of the whole reply, and react-markdown, remark-gfm, remark-math, rehype-katex, unified, and the hast chain left the browser bundle (`mdast-util-math` and `micromark-util-sanitize-uri` became direct dependencies; both were already transitive). The package owns ~25 node mappings, their tests, and the KaTeX DOM conversion — priced against the fixture contract that freezes their output. Two behavioral deviations, both healed by the settled full parse at finalize: a reference-style link or footnote whose definition lands on the other side of a freeze boundary renders literally while streaming, and a footnote reference can flash back to literal text when its definition freezes while the referencing block is still unstable. This module and KaTeX conversion assume a browser DOM (`DOMParser`), which the client-only package already did. diff --git a/.agents/notes/implemented/architecture/2026-08-06-web-markdown-incremental-ast-renderer.zh.md b/.agents/notes/implemented/architecture/2026-08-06-web-markdown-incremental-ast-renderer.zh.md new file mode 100644 index 0000000000..2e00977da5 --- /dev/null +++ b/.agents/notes/implemented/architecture/2026-08-06-web-markdown-incremental-ast-renderer.zh.md @@ -0,0 +1,33 @@ +# Agent Note: 经由直接 mdast 渲染器的增量流式 Markdown + +Status: implemented + +[English](2026-08-06-web-markdown-incremental-ast-renderer.md) | 中文 + +## Problem + +`MarkdownText` 在每次流式发布时都重新解析整个已累积的回复:react-markdown 的纯字符串 API 每次渲染都新建 unified processor,并对全文跑完 micromark → mdast → hast → React,因此每个 chunk 的主线程工作量随回复长度线性增长,整个流的累计成本随之二次增长。既有缓解手段(帧级合并、隔离的流式尾部、围栏 plain 臂)约束的是这份工作跑多频繁、波及多广,从未约束每次重新解析多少文本。修复它需要 AST 级输入——冻结已定型的块、只重新解析源文本尾部——这是纯字符串封装在结构上无法表达的。 + +## Decision + +`MarkdownText` 直接渲染 mdast,并在流式期间增量解析: + +- **语法**([parse.ts](../../../../packages/client/ui-primitives/src/markdown/parse.ts)):`parseGfm`(流式臂与 `extractMarkdownPlainText`)和 `parseGfmWithMath`(定稿臂)以被替换的 remark 插件所包装的同一组 micromark 扩展调用 `mdast-util-from-markdown`,因此各处块边界完全一致。`mathCompatibility`(原 `remarkMathCompatibility`)现在直接导出其 micromark 扩展。 +- **增量解析**([incremental.ts](../../../../packages/client/ui-primitives/src/markdown/incremental.ts)):CommonMark 块解析按行推进,追加文本只会重塑解析前沿。`IncrementalMarkdownParser` 保留末尾两个块不稳定(最后一块是前沿;倒数第二块是安全裕量),冻结其前的所有块,只从最后一个冻结块的 `position.end.offset` 起重新解析源尾部——用的是解析器自己的偏移量,没有任何自制源扫描。每个源区间在整个流中解析 O(1) 次而非每 chunk 一次;单个巨型块(未闭合围栏)退化为旧的全量重解析成本,不会更差。非追加输入在递增的 generation 下重置状态。 +- **渲染**([render.tsx](../../../../packages/client/ui-primitives/src/markdown/render.tsx)、[katex.tsx](../../../../packages/client/ui-primitives/src/markdown/katex.tsx)):一个对 mdast 节点类型的 switch 取代 remark-rehype + react-markdown,逐字节复刻被替换管线的 DOM——表格对齐渲染为 `text-align` 样式、紧凑列表段落解包、任务列表类名与复选框空格、脚注区(其页内锚点本就被协议白名单降为纯文本)、字面 raw HTML、会与字面 HTML 文本相邻显形的分隔换行,以及 rehype-katex 的三臂容错链,KaTeX HTML 经浏览器自带的 `DOMParser` 映射为 React(无包裹元素,首/末子元素的 margin 规则仍能作用于 `.katex-display`;React 18 会把 `.katex-mathml` 子树放进 HTML 命名空间,与被替换管线完全一致——既有限制,不在本对等性契约范围内,对承担视觉渲染的 `.katex-html` 臂不可见)。冻结块缓存其 React 元素并保持源偏移 key,跨过冻结边界时走 reconcile 而非重挂载;`MarkdownText` 已 memo 化。 + +DOM 由 `tests/fixtures/markdown-dom` 钉死:fixture 录制自替换前的 react-markdown 实现,新渲染器必须在空白规整序列化器下复现。fixture 差异即用户可见的 markdown 样式变更,必须按此评审,绝不能为重构而重录。`tests/markdown-incremental.spec.tsx` 承载等价性性质——以 1/3/7/16 字节分块,在每个追加前缀处,常驻组件的 DOM 都等于全新挂载——外加冻结边界的 DOM 节点同一性与重置行为。 + +这推翻了[助手 Markdown Note](../feature/2026-07-23-web-assistant-markdown.md) 中被否决的备选("维护一个自定义 React walker"):增量需求是当时不存在的新证据,walker 的安全敏感分支(URL 白名单、图片策略、惰性 HTML)本就是产品自有函数,而该依赖不再删减自有代码——它阻塞了架构。该 Note 的不可信输出策略与渲染器选型不变。 + +## Alternatives considered + +**保留 react-markdown,把源文本切成逐段 `` 实例。** 渲染器零自有成本,但每帧对尾部解析两次(边界检测 + 渲染),定稿数学仍要全量重解析,hast 构建与逐渲染 processor 依旧存在,且块跨过冻结边界时会重挂载——元素树无法跨实例缓存。 + +**用 `mdast-util-to-hast` + `hast-util-to-jsx-runtime` 渲染缓存的 mdast。** 白拿上游节点映射,但每帧保留 hast 中间层,并为一个映射面小、封闭、且已被 fixture 钉死的管线引入两个新直接依赖。 + +**用 `hast-util-from-html-isomorphic` 解析 KaTeX 输出(rehype-katex 的做法)。** 为解析可信、词汇受限的 KaTeX 输出把基于 parse5 的 HTML 解析器拉进 bundle,而浏览器自带的 `DOMParser`(带规范的 SVG/MathML 属性调整)解析结果完全相同。 + +## Consequences + +流式的每 chunk 工作量现在跟随不稳定尾部而非整个回复,react-markdown、remark-gfm、remark-math、rehype-katex、unified 及 hast 链退出浏览器 bundle(`mdast-util-math` 与 `micromark-util-sanitize-uri` 成为直接依赖;两者原本就是传递依赖)。包自有约 25 个节点映射、其测试以及 KaTeX DOM 转换——代价由冻结其输出的 fixture 契约对冲。两个行为偏差,均在定稿的全量解析处自愈:定义落在冻结边界另一侧的引用式链接或脚注在流式期间渲染为字面文本;当脚注定义先冻结而引用块仍不稳定时,脚注引用可能闪回字面文本。本模块与 KaTeX 转换假定浏览器 DOM(`DOMParser`),这个 client-only 包本就如此。 diff --git a/.agents/notes/implemented/architecture/2026-08-06-web-shell-dist-chunk-layout.i18n.yaml b/.agents/notes/implemented/architecture/2026-08-06-web-shell-dist-chunk-layout.i18n.yaml new file mode 100644 index 0000000000..815f5eee75 --- /dev/null +++ b/.agents/notes/implemented/architecture/2026-08-06-web-shell-dist-chunk-layout.i18n.yaml @@ -0,0 +1,6 @@ +# Bilingual-pair consistency record (docs/i18n/README.md): the git blob hash of each +# side as of the last confirmed-consistent state.

Nav labels may be locale-following thunks, so the nav projection resolves them through `resolveSlotLabel` and re-renders on the section ledger bump or the locale revision (an optional `ctx.get('locale')` read; no hard locale dependency). -The shell projects the onboarding ledger into ascending order and mounts exactly one page at a time in a body-level stage while marking the underlying app root inert. The active registrant receives its id, `complete()`, and an `openSection(id)` callback; completing or skipping transfers ownership to the next entry. Registrants own durable completion, capability readiness, copy, and mutations, so independently registered flows cannot stack and the shell does not become a second configuration fact source. +The shell projects the onboarding ledger into ascending order and mounts exactly one page at a time; the takeover chrome (body-level stage, mask, app-root `inert`) belongs to the step itself through ui-primitives' `OnboardingSurface`, so a mounted step still resolving its private facts renders null and neither paints nor blocks anything — the shell shows no empty stage while a step decides. The active registrant receives its id, `complete()`, and an `openSection(id)` callback; completing or skipping transfers ownership to the next entry. Registrants own durable completion, capability readiness, copy, mutations, and the surface wrap, so independently registered flows cannot stack and the shell does not become a second configuration fact source. ## Model Experience diff --git a/packages/client/ui-settings/README.zh.md b/packages/client/ui-settings/README.zh.md index 8ae3bdf34f..8e7bd7325b 100644 --- a/packages/client/ui-settings/README.zh.md +++ b/packages/client/ui-settings/README.zh.md @@ -4,7 +4,7 @@ 设置外壳插件：一个纯组合表层。它以触发控件和模态设置面板占用 `sidebar.settings`，并声明由注册方填充的 slot：`settings.trigger`／`settings.header`／`settings.close`（界面框架内容）、`settings.action`（内容标题栏中的有序操作）、`settings.section`（每项功能一页）和 `settings.onboarding`（由各功能持有、显示在全视口展示层中的有序页面）。外壳不自带文案：所有文本都来自注册方（ui-settings-general 拥有界面框架、「通用」分区和产品声明；各功能拥有各自的操作、分区、行和条件式首次使用引导页面）。导航 label 可以是跟随语言的 thunk，因此导航投影经 `resolveSlotLabel` 解析，并在分区账本更新或 locale revision 变化时重新渲染（`ctx.get('locale')` 可选读取，无硬 locale 依赖）。 -外壳将首次使用引导记录按升序投影，在 body 层级的展示层中每次只挂载一个页面，同时将下层应用根节点标记为 `inert`。当前注册方会收到该条目的 id、`complete()` 和 `openSection(id)` 回调；完成或跳过当前页面后，所有权转交给下一项。持久化完成状态、能力就绪状态、文案和变更操作均由注册方持有，因此独立注册的流程无法堆叠，外壳也不会成为第二个配置事实来源。 +外壳将首次使用引导记录按升序投影，每次只挂载一个页面；接管界面框架（body 层级的展示层、遮罩、应用根节点 `inert`）经 ui-primitives 的 `OnboardingSurface` 由步骤自身持有，因此已挂载但仍在判定私有事实的步骤渲染 null 时不绘制也不阻塞任何内容——步骤判定期间外壳不会露出空白展示层。当前注册方会收到该条目的 id、`complete()` 和 `openSection(id)` 回调；完成或跳过当前页面后，所有权转交给下一项。持久化完成状态、能力就绪状态、文案、变更操作以及页面的外层包裹均由注册方持有，因此独立注册的流程无法堆叠，外壳也不会成为第二个配置事实来源。 ## 模型体验 diff --git a/packages/client/ui-settings/src/client/SettingsRoot.module.css b/packages/client/ui-settings/src/client/SettingsRoot.module.css index 72c188e019..e70558081a 100644 --- a/packages/client/ui-settings/src/client/SettingsRoot.module.css +++ b/packages/client/ui-settings/src/client/SettingsRoot.module.css @@ -219,33 +219,3 @@ clip: rect(0 0 0 0); white-space: nowrap; } - -/* First-run stage: keep the product top bar visible, then let onboarding own - the complete workspace instead of presenting another settings modal. */ -.onboardingOverlay { - position: fixed; - inset: 0; - z-index: 1100; -} - -/* Mask */ -.onboardingMask { - position: absolute; - left: 0px; - right: 0px; - top: 80px; - bottom: 0px; - background: rgba(0, 0, 0, 0.24); - /* Mask-blur */ - backdrop-filter: blur(2px); -} - -.onboardingStage { - position: absolute; - z-index: 1; - inset: 0; - display: flex; - justify-content: center; - overflow: hidden; - background: var(--dsw-alias-bg-layer-1); -} diff --git a/packages/client/ui-settings/src/client/SettingsRoot.tsx b/packages/client/ui-settings/src/client/SettingsRoot.tsx index 45055753ac..d6b2e8ef5a 100644 --- a/packages/client/ui-settings/src/client/SettingsRoot.tsx +++ b/packages/client/ui-settings/src/client/SettingsRoot.tsx @@ -7,10 +7,11 @@ * aria-labelledby the title node; close: visually-hidden slot text).
