The hand-written direction won over adding a hint/grouping system, and a further simplification removed the reference input entirely: the card's primary field is one **API key** input, a whole-section provider without a configured key opens as its setup card, and the collapsed 自定义设置 fold carries the curated per-family extras (`baseURL` for both families, `reasoningEffort` for deepseek / `reasoning` for pi-ai, plus direct DeepSeek model rows with `id`, `name`, and `contextWindow`). Existing model fields outside that visible set survive array edits; retry policy, timeouts, and other fields remain owned by `settings.yaml`. Validation still runs the rehydrated schema before writing, while adapter-specific checks reject catalog invariants that the serialized schema cannot express. The card's colors resolve through the `--dsw-alias-*` design tokens; it had named `--border`/`--surface`/`--text-*`, which nothing in this app defines, so it rendered their light-mode fallbacks and stayed light under the dark theme. The model catalog takes the row shape the pi-ai provider form introduces: one bordered entry per model, id and display name on the row, and the capacities behind the row's own disclosure, so the two editors read as one design rather than diverging. Every field keeps the indexed `aria-label` that names it. Both capacities are text fields reading a decimal `K`/`M` suffix (`1M` is 1000K, matching how capacities are quoted) and storing the plain count: a field holds the typed text while it has focus, because re-deriving it from the parsed count on every keystroke would rewrite `1000` to `1K` mid-word, and text that does not parse stays on screen so the save-time rejection names a row the user can still see. The shared class names carry only declared token spellings: `--dsw-alias-border-subtle`, `--dsw-alias-text-tertiary`, and `--dsw-alias-text-primary` are undeclared, so naming them resolves to the light-mode literals in their fallback slots. A styles test now rejects any `--dsw-*` name the token sheet does not declare, so the next editor to name one fails rather than shipping a light-only surface. -**The Models page is a three-domain join with service-shaped apply semantics.** Rows are configured providers; the add card's select is the dormant directory remainder.

The key path stays reference-shaped without ever showing a reference: a typed key stores **write-only** through `credentials.set` under the profile's `apiKeyEnv`, deriving `_API_KEY` when none exists (the pi-ai profile records the derivation only when a key is entered), so `settings.yaml` never carries a key value; a blank pi-ai key materializes a reference-free profile and preserves provider-native authentication.

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 log is the sole authority; this design adds no domain index, checkpoint of its own, or in-process memo. The `sessionProjectionCache` checkpoint the second rung reads is an existing composition item's derived data, which the list only reads. Values are computed on read and discarded. Seeded candidates use a body-bearing observation to classify the identity against the exact cut; unseeded cached identities need no seq gate because every valid seq is owned. - 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. @@ -127,25 +127,24 @@ For each enumerated child, the ladder's result maps to a row through four states 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`).

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. +- Rung 2's later-event window applies only to an unseeded child: a cache row lands right after the first descriptor, the log then appends a second descriptor (or a malformed payload setting the null sentinel), and the process crashes before the next checkpoint. Cold listing can keep serving the old identity until a live run or cache write replaces the row. The precondition violates the provider's append-exactly-once contract and also requires missing every mandatory checkpoint; healthy children are unaffected. Seeded children never take rung 2 without the body-owned cut. -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's load requirement changes — `sessionQuery` dropped from inject, `sessionProjections` added as a required injection). 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). +Consuming surfaces keep the same row and diagnostic wire shape. `list_agents` reaches the required query corpus plus projection registry; live identities come from the registry snapshot and cold identities from cache or query observation.

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. +`packages/subagent/subagent/tests/list-children.spec.ts` pins this contract: live identity checks use `Session.isOwnSeq()`; an unseeded cold identity may use the cache at cut zero; seeded candidates skip that cache rung and use an observation carrying `inheritedEventCount`; ancestor identities fail the own-suffix check; absent, null, poisoned, and unavailable cache/observation cases fall through or produce the documented diagnostic; lifecycle tampering degrades to `corrupt` across the complete witness field set. The existing keyless snapshots keep the healthy wire and model-visible surfaces fixed, while `subagent-diagnostic` pins diagnostic classification. ## 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, loading the `list_agents` plugin no longer requires `sessionQuery`, and `sessionProjections` becomes a required injection of `SubagentRuntime` — a deployment without the projection registry never activates the service (the mandatory seam). +- The subagent list requires the Session query corpus and projection registry; missing services fail explicitly instead of producing incomplete rows. The optional projection cache changes only the number of body reads. - Identity interpretation exists only in the single unit registered with the registry: the list's three-rung ladder and GUI history's cold read use its live, cached, or observed wire snapshots, and no hand-written bypass fold exists; if some future consuming surface bypasses the unit 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. +- The diagnostic and enumeration semantics leaves five boundary deviations (multiple descriptors resolving to the last, header conflicts going unnoticed, damaged-source read failures changing classification, an unknown parent yielding an empty list instead of not-found, and the unseeded rung-2 later-event window).

That seed costs real tokens — the inherited history is re-sent in every child request — and its one concrete payoff is provider-side prefix reuse: under the same provider and model, a child request whose leading bytes are identical to the parent's re-prefills none of the shared span. Anything a child scope adds *ahead* of the inherited history spends that payoff, because reuse stops at the first differing byte. +Fork differs from spawn by seeding the child Session with the parent's completed-turn prefix. That seed costs tokens, and its intended payoff is provider-side prefix reuse: under the same provider and model, a child request whose leading bytes match the parent's does not prefill the shared span again. A child-only system-prompt section or tool schema ahead of the inherited history defeats that payoff. -The child-scoped `report` return channel is now the largest such addition, and since [the report obligation](../feature/2026-08-06-continuable-child-report-obligation.md) it is two deltas rather than one: the `report` tool schema and the `tool:report` system-prompt section. Both live in the request head — the system block and the tool block precede every message — so a continuable forked child invalidates reuse before the first inherited turn and re-prefills the whole transcript it was forked to reuse. That composition pays fork's duplication cost and collects none of its benefit, while the parent still holds a reusable prefix the child could have shared. +The earlier shipped composition avoided this mismatch by keeping forked children one-shot. That restriction was a consequence of the former child-only return tool, not an intrinsic property of continuable fork. ## Decision -Every shipped composition inherits the fork delegation tool's `backgroundMode: one-shot` from the [base bundle](../../../../packages/bundle/base/cordis.patch.yml). The base bundle leaves `run_in_background` available because it also mounts the task service needed to settle background work. +The model-facing `send_message` tool is registered globally for every Agent in a composition. A continuable forked child therefore receives the same tool name, description, schema, and ordering as its parent. Its initial task is appended after the inherited Session seed, and the task includes the direct parent id plus guidance to return results with `send_message({ agent_id, message })` when that tool is visible to the child. -One-shot children — foreground and background alike — are created through `SubagentRuntime.start()`, which never enters the continuable activation-setup registry, so neither `report` nor its prompt section is installed. A forked one-shot child's system prompt and tool schemas therefore equal its parent's, apart from the `persona` and `toolFilter` deltas a deployment opts into per delegation tool. +The base and headless compositions retain one-shot fork as their conservative lifecycle policy. The `cordis`, `standard`, and `ptc` CLI presets may bind fork to the continuable lifecycle because that binding no longer inserts child-only request-head fields. `ForkInProcessProvider.prepareContinuable()` and `ctx.subagents.startContinuable()` remain the implementation seam for those presets. -`spawn` keeps `backgroundMode: continuable`. Continuable children and the report obligation ship unchanged for the provider whose child starts with no inherited prefix to protect, so this decision costs the report channel nothing. - -### The restriction is composition, not code - -`ForkInProcessProvider.prepareContinuable` stays implemented and `ctx.subagents.startContinuable()` still accepts `fork`; only the shipped `cordis.yml` rows changed. `tool-subagent` knows both the provider's `inheritsParentContext` and its own `backgroundMode` at mount, so a load-time rejection of the pair was available and is deliberately not added: the pair is not wrong in general. It is wrong only while a child-scope delta precedes inherited history, and the package that creates that delta — [`dsh-tool-subagent-report`](../../../../packages/subagent/tool-subagent-report/README.md) — is separately installable and, by its own design, invisible to `tool-subagent`. A deployment that omits the report package can run continuable forked children with the prefix intact. Encoding one roster's consequence as a delegation-tool invariant would make the tool assert something it cannot observe. - -The reintroduction condition is recorded as a `TODO(fork-continuable-prefix-reuse)` marker on `prepareContinuable` itself, the one method the shipped compositions do not call, and tracked as issue #2124: continuable fork reopens when a child's system prompt and tool schemas can match its parent's byte for byte. +Byte-identical prefix reuse is qualified by explicit deployment choices. A fork delegation that applies a child persona or `toolFilter` may still change the request head. In particular, filtering out `send_message` removes both the schema and the return guidance from the child; the runtime does not bypass an explicit allow-list. ## Alternatives considered -**Reject `inheritsParentContext` + `continuable` at mount.** A loud load-time failure would prevent silent reintroduction, which is what the configuration change cannot do. Rejected because the delegation tool cannot see the report package and the combination is legitimate without it; the invariant would be false for a deployment that never installs a child-scope delta, and `tool-subagent` would be asserting a fact owned by the roster. +**Keep every fork one-shot.** This preserves the prefix but unnecessarily gives up durable, multi-turn forked children after the child-only schema difference is gone. -**Stop mounting the fork provider at all.** This was the broader form of the restriction. Rejected because foreground fork *is* the prefix-reusing case and is untouched by the report channel, so a full ban gives up the capability without buying anything the one-shot binding does not already buy — and would leave no shipped composition exercising session seeding. +**Install a child-only return alias.** A recipient-free alias would make child calls shorter, but it would recreate a tool-schema and prompt delta before inherited history and duplicate the adjacent-Agent operation. -**Ship continuable forked children and accept the loss.** Rejected because the loss is total rather than marginal: reuse breaks ahead of the inherited history, so the child pays full prefill on a transcript it duplicated for the sole purpose of not paying it. A deployment that wants a long-lived child with no inherited context already has `spawn`. +**Add the return instruction to the system prompt.** This would place child-only bytes ahead of inherited messages. Appending it to the initial user task preserves the inherited prefix and keeps the parent id next to the task that needs it. -**Make `report` visible to every Agent.** A global registration would restore byte-identical prefixes by giving parent and child the same schema and section. Rejected because roots, one-shot children, remote children, and agentless callers would advertise a tool with no derivable recipient, and execution-time rejection would make schema visibility disagree with authority — the scope-local decision the [report tool Agent Note](../feature/2026-07-30-continuable-subagent-report-tool.md) already settled. - -**Install the child-scope deltas after the inherited history.** Rejected as unrepresentable: the system prompt and the tool schemas are request-head structures in every provider's wire format, so no ordering within them can place a child-only addition behind the message list. +**Ignore an explicit child `toolFilter`.** Structural return tools previously bypassed the child allow-list. Rejected because a declared tool restriction must determine both schema visibility and guidance; hidden authority would make the model-facing roster inaccurate. ## Consequences -- No shipped composition creates a continuable forked child; `subagent_fork` returns a result to its caller's turn, and `send_message` addresses only spawned children. -- A forked child's request prefix stays byte-identical to its parent's unless the deployment configures `persona` or `toolFilter` on the fork delegation tool, so the token cost of seeding buys provider-side reuse again. -- The fork provider's continuable path has no production caller and no assembled-composition coverage. It keeps its package-level tests, and the seam still accepts it, so a bundle or `--patch` overlay can reintroduce it with no code change and no warning. -- `subagent_fork`'s model-visible schema changes: the continuable background wording is replaced by the one-shot task wording in the base bundle, and disappears entirely from the two examples. The affected keyless snapshot tool-schema sidecars are re-recorded in the same change. -- The report obligation's reach narrows to spawned children in shipped deployments. Its default `next-step` scheduling, authority model, and coverage remain independent of fork composition. +- Parent and continuable-fork child expose byte-identical ordered tool schemas when the delegation does not request a persona or tool filter. +- The inherited Session seed precedes the child's initial task and return guidance. +- The base and headless profiles keep one-shot fork, while selected CLI presets exercise continuable fork without a child-only request-head addition. +- A child sends zero or more messages to its direct parent explicitly; its final answer is not implicitly copied. The manager-owned settlement notice remains unconditional and separate. +- Keyless snapshots and package tests pin schema equality, inherited-history ordering, parent-id guidance, and child-to-parent delivery through the same `send_message` operation used in the other direction. ### Accepted risks -The constraint lives in three configuration files and a code comment, not in a gate. A future bundle row or profile patch can set `backgroundMode: continuable` on a fork tool and silently reintroduce the prefix loss; nothing fails loud.

-**干脆不挂载 fork 提供方。** 这是该限制更彻底的形式。否决的原因是前台 fork *正是*复用前缀的那种情形，且不受 report 通道影响，因此全面禁用会在不换来任何 one-shot 绑定尚未换来的东西的同时放弃该能力——并且随附组合将没有任何一个演练 session 初始内容。 - -**照常随附可继续的 fork child 并接受这份损失。** 否决的原因是这份损失是全额而非边际的：复用在继承历史之前就已中断，于是 child 为一份自己复制过来、目的恰恰是不必付费的 transcript 付了全额预填充。想要一个没有继承上下文的长期 child 的部署，本来就有 `spawn`。 - -**让 `report` 对每个 Agent 可见。** 全局注册会通过让 parent 与 child 拥有相同的 schema 与 section 来恢复逐字节相同的前缀。否决的原因是根 agent、one-shot child、远端 child 与无 agent 调用方都会宣告一件推导不出收件方的工具，而执行期拒绝会让 schema 可见性与权限彼此矛盾——这正是[report 工具 Agent Note](../feature/2026-07-30-continuable-subagent-report-tool.zh.md)已经定下的作用域局部决策。 - -**把 child 作用域增量安装到继承历史之后。** 否决的原因是它无法表达：在每个提供方的协议格式中，系统提示词与工具 schema 都是请求头部结构，因此它们内部的任何排序都无法把仅属于 child 的添加放到消息列表之后。 +**忽略显式 child `toolFilter`。** 结构性返回工具过去会绕过 child allow-list。否决该方案，因为声明的工具限制必须同时决定 schema 可见性与指引；隐藏权限会让面向模型的工具清单失真。 ## 后果 -- 没有任何随附组合会创建可继续的 fork child；`subagent_fork` 把结果返回给调用方的轮次，而 `send_message` 只寻址 spawn 出的 child。 -- 除非部署在 fork 委派工具上配置了 `persona` 或 `toolFilter`，fork child 的请求前缀与其 parent 逐字节相同，因此初始内容的 token 成本重新换来了提供方侧的复用。 -- fork 提供方的可继续路径没有生产调用方，也没有整体组装层面的覆盖。它保留自己的包内测试，seam 也仍然接受它，因此某个组合包或 `--patch` 覆盖层可以无需改动代码、也不会有任何警告地把它重新引入。 -- `subagent_fork` 面向模型的 schema 发生变化：base 组合包中可继续的后台措辞被 one-shot 的 task 措辞取代，在两个示例中则完全消失。受影响的无密钥快照工具 schema 伴随文件在同一次改动中重新记录。 -- 在随附部署中，report 义务的覆盖范围收窄到 spawn 出的 child。它的 `next-step` 默认调度、权限模型与覆盖仍独立于 fork 组合。 +- 未请求 persona 或工具过滤时，parent 与可继续 fork child 暴露逐字节相同且顺序一致的工具 schema。 +- 继承的 Session 种子位于 child 初始任务及其返回指引之前。 +- base 与 headless profile 保持 one-shot fork；选定的 CLI preset 会在没有 child-only 请求头增量的前提下使用可继续 fork。 +- child 显式向直接 parent 发送零条或多条消息；最终回答不会被隐式复制。管理器负责的结算通知仍然无条件执行，并且与 Agent 消息分离。 +- keyless snapshot 与包测试固定 schema 相等性、继承历史顺序、parent-id 指引，以及通过同一个 `send_message` 操作完成的 child-to-parent 投递。 -### 已接受的风险 +### 已接受风险 -该限制存在于三个配置文件与一处代码注释中，而不在门禁里。未来某个组合包行或 profile 补丁可以在 fork 工具上设置 `backgroundMode: continuable`，从而悄然重新引入前缀损失；没有任何东西会失败得很响亮。这就是不把某一份插件清单的后果写入 `tool-subagent` 所接受的代价。 +提供方侧前缀复用仍取决于选定的提供方和模型，以及是否不存在显式 persona 或工具过滤差异。harness 证明的是自己组装出的请求头输入相等，而不是提供方的缓存行为。 diff --git a/.agents/notes/implemented/architecture/2026-08-25-sparse-first-party-prompt-section-orders.i18n.yaml b/.agents/notes/implemented/architecture/2026-08-25-sparse-first-party-prompt-section-orders.i18n.yaml index d91028172d..9ac6e44cd5 100644 --- a/.agents/notes/implemented/architecture/2026-08-25-sparse-first-party-prompt-section-orders.i18n.yaml +++ b/.agents/notes/implemented/architecture/2026-08-25-sparse-first-party-prompt-section-orders.i18n.yaml @@ -2,5 +2,5 @@ # side as of the last confirmed-consistent state.

A parent called `send_message({ subagent_id, message })`, which delegated to a FIFO `followup` service operation.

A running target receives it at the nearest step boundary; an idle target starts a turn. An absent direct child is cold-resumed through the existing continuation lifecycle before the same Steer delivery. The manager retains waking-send accounting so a continuation-managed target cannot settle between synchronous inbox insertion and driver admission. + +Every direction uses one durable source.

The standard definition carries a process-stable internal identity that a scoped same-name tool does not satisfy. A child `toolFilter` may explicitly remove the inherited tool, and a scoped replacement may provide different semantics; neither case receives the standard call instruction. When the standard tool remains visible, the continuation manager appends the JSON-encoded direct parent id and the instruction to send one self-contained result before finishing, plus earlier actionable findings, to the child's initial user task. For a fork child this task follows the inherited completed-turn prefix; no child-only system-prompt section or tool schema precedes that prefix. + +The instruction is guidance, not settlement enforcement. Sending does not end the child's turn, zero or several calls remain mechanically valid, and the runtime never rejects a child for staying silent. The manager-owned `subagent-settled` notice remains unconditional and separately attributed because it records how an Activation ended and preserves terminal output when the child cannot cooperate. + +Human browser prompts are not model-authored Agent messages.

The unified tool gives up the recipient-free child shortcut and the old ability for a structural return tool to survive an explicit child allow-list. Those capabilities return only if a concrete use case requires semantics that an adjacent `agent_id` and fixed Steer cannot express; reintroducing them requires a distinct model operation and prefix-cost evidence, not an alias over `sendMessage()`. + +## Alternatives considered + +**Keep `followup` and add child-to-parent routing.** The name promises a later turn and inherits `Agent.followup()` semantics. It would obscure the chosen nearest-step behavior and preserve a parent-centric name for a direction-neutral capability. + +**Keep a recipient-free `report` wrapper over `sendMessage()`.** This preserves a convenient child shortcut and lets a scope-local registration survive global tool filtering. It loses because the separate schema and prompt duplicate one operation, make parent and child request heads differ, and let equivalent directions drift again. + +**Make `report` global.** Roots, one-shot children, remote children, and agentless callers cannot derive a report recipient. Advertising it globally would make schema visibility disagree with authority, while `send_message` already makes the recipient explicit. + +**Turn every child final message into an implicit send.** A long-lived child may have nothing useful to send in one turn and several findings in another. Automatic delivery would merge model-authored communication with the runtime's settlement account and could not replace the unconditional notice on errors, cancellation, or token exhaustion. + +**Rely only on the tool description.** A tool description helps after the model considers that tool; the failure mode is a child that believes it is finished without considering any return call. Initial-task guidance reaches that decision without changing the inherited system or tool prefix. + +**Keep quiet delivery as deployment policy.** A quiet model-authored message can be accepted while an idle target never reads it. Fixed Steer gives both directions one delivery meaning and preserves accepted order with later settlement notices. + +## Consequences + +- Model consumers expose one `send_message({ agent_id, message })` definition to parents and children, with no model-selected Queue versus Steer parameter. +- The continuation manager remains the sole owner of adjacency authorization, residency, cold resume, waking admission, and teardown races. +- Accepted messages may extend a running target's current turn; messages waiting together share next-step FIFO ordering. +- Caller cancellation owns work only until inbox acceptance and does not retract an accepted message or dispose the target. +- The initial task carries JSON-encoded dynamic parent addressing after a fork prefix, while the request-head system prompt and tool ordering remain reusable. +- Human prompts, settlement notices, QueueDock, and the base bundle's one-shot fork policy remain separate decisions. + +This decision consolidates and removes the fully superseded report-tool and child-report-obligation records.

An event reference names an existing row, while a prefix length, next append position, or read cut names a gap and may equal the event count. The compiler therefore accepted an offset where an event identity was required and could not expose a missed sequence-field migration. + +`SessionHeader.seedLength` also mixed a v0 storage coordinate into metadata used by body-free readers.

Arithmetic returns an ordinary number and re-enters either domain through its validating constructor. + +The logical `SessionHeader` carries `isSeeded: boolean` and no numeric seed cut. Body-bearing storage values and observations carry `inheritedEventCount` beside the header; `Session.ownEvents()` and `Session.isOwnSeq()` hide the comparison from ordinary consumers. A seeded constructor requires an explicit seed and exact cut, including an empty seed with cut zero, because constructor input may contain child-owned setup events after the inherited prefix. + +The v0 JSONL header remains byte-compatible: absent `seedLength` decodes to `isSeeded: false` with cut zero, while present zero or nonzero values decode to `isSeeded: true` with the exact cut. Header-only listing translates only the presence bit. API, SDK, DeepSeek, telemetry, query-row, and JSON representations continue to carry ordinary numbers; their owning adapters validate and brand values when they enter same-process domain code. + +## Admission and ownership + +Domain constructors reject negative, fractional, non-finite, and unsafe integer values. Parsers validate a raw number once and retain the parsed object where the brand does not require a runtime wrapper. A compile-time brand does not discover unknown numeric fields in an external event; a format migration still needs an exhaustive owner disposition and must refuse schemas it cannot safely rewrite. + +`session/end-seed` remains a lifecycle marker, not the source of the inherited cut.

Reinstate only if a deployment states a turn-boundary latency requirement `scheduledDelayMillis` cannot meet — and then by calling the retained `BatchLogRecordProcessor`'s own `forceFlush()`, never the provider's timeout-wrapped one. diff --git a/.agents/notes/implemented/feature/2026-07-23-session-telemetry-otel-revival.zh.md b/.agents/notes/implemented/feature/2026-07-23-session-telemetry-otel-revival.zh.md index 9874598a58..6c046c5f96 100644 --- a/.agents/notes/implemented/feature/2026-07-23-session-telemetry-otel-revival.zh.md +++ b/.agents/notes/implemented/feature/2026-07-23-session-telemetry-otel-revival.zh.md @@ -29,7 +29,7 @@ Status: implemented **映射到 OTel span（GenAI 语义约定）而非日志。** 本次复活否决：分支实现的日志映射已经过评审、形态可交付；span 模型对可 fork、可中断的会话有损，留给将来真正有 span 查询需求的消费方。 -**handoff 游标未存活时全量回放日志（重新导出构造函数种子）。** 首轮复活曾交付此方案，其后收窄：接管操作现在从会话的构造边界起回放（`Session.firstLiveSeq`，即构造函数种子长度，这一事实会话早已校验过却未曾暴露；`header.seedLength` 不能胜任：它是持久保存的 fork 谱系（lineage）值，而恢复会话的构造函数种子是其完整的已存储日志）。恢复会话的历史已由上一个进程以同一 id 发出，fork 继承的前缀也已在父会话的流中发出；再次导出任何一者，都会让每次恢复为其完整历史重复付费，并在没有原生摄取去重的 OTLP 后端上使查询时的计数翻倍。接收端基于 `session.parent_id` + `session.seed_length` 拼接 fork 谱系。此次收窄放弃的内容与至多一次立场一致：恢复不再回填上一个进程未能投递的记录（彼时遥测未挂载，或崩溃时仍在队列中）——这本是全量回放唯一的真实收益，代价却由常见情形承担。提出回填要求的部署需要的是上文已推迟的 outbox，而不是回放。该边界同样吞掉 `SessionPersistence.load()` 修复被崩溃打断的日志时写入的合成轮次关闭事件（它们落在 `firstLiveSeq` 之前，尽管在上一个进程中从未存在过）。这是有意为之，而非附带效果：远端轮次的真实尾部记录已随崩溃进程的队列一同消亡，导出合成关闭事件无法补全该轮次，只会让一个未完成的轮次看起来已经关闭。导出的流忠实于崩溃进程实际发出的内容；接收端会把恢复后的流中一个从未关闭的轮次读作「上一个进程死在了该轮次之内」（OTel README 陈述了这条规则），其后干净的 `shutdown` 标记也只证明恢复后进程自身的退出。若为让修复以实时事件的身份导出而将修复前边界贯穿 load/prepare 传递，将使三个包相互耦合，只为抹除这一信号。 +**handoff 游标未存活时全量回放日志（重新导出构造函数种子）。** 首轮复活曾交付此方案，其后收窄：接管操作现在从会话的构造边界起回放（`Session.firstLiveSeq`，即构造函数种子长度；`Session.inheritedEventCount` 不能胜任，因为它是持久保存的 fork 谱系 cut，而恢复会话的构造函数种子是其完整的已存储日志）。恢复会话的历史已由上一个进程以同一 id 发出，fork 继承的前缀也已在父会话的流中发出；再次导出任何一者，都会让每次恢复为其完整历史重复付费，并在没有原生摄取去重的 OTLP 后端上使查询时的计数翻倍。接收端基于 `session.parent_id` + `session.seed_length` 拼接 fork 谱系。此次收窄放弃的内容与至多一次立场一致：恢复不再回填上一个进程未能投递的记录（彼时遥测未挂载，或崩溃时仍在队列中）——这本是全量回放唯一的真实收益，代价却由常见情形承担。提出回填要求的部署需要的是上文已推迟的 outbox，而不是回放。该边界同样吞掉 `SessionPersistence.load()` 修复被崩溃打断的日志时写入的合成轮次关闭事件（它们落在 `firstLiveSeq` 之前，尽管在上一个进程中从未存在过）。这是有意为之，而非附带效果：远端轮次的真实尾部记录已随崩溃进程的队列一同消亡，导出合成关闭事件无法补全该轮次，只会让一个未完成的轮次看起来已经关闭。导出的流忠实于崩溃进程实际发出的内容；接收端会把恢复后的流中一个从未关闭的轮次读作「上一个进程死在了该轮次之内」（OTel README 陈述了这条规则），其后干净的 `shutdown` 标记也只证明恢复后进程自身的退出。若为让修复以实时事件的身份导出而将修复前边界贯穿 load/prepare 传递，将使三个包相互耦合，只为抹除这一信号。 **将 seam 的轮次边界 `flush()` 提示转发到 OTel 提供方的 `forceFlush()`。** 首轮复活曾交付此转发，其后移除：三条不同的静默丢失路径共用同一份包装层状态——dispose 与进行中的 flush 之间的竞态（SDK 的并发 flush 防护会令 shutdown 的内部排空被跳过）、相互重叠的提示顶掉留存的 promise、以及提供方固定的 30 秒 flush 超时在批处理器仍在排空时便 reject。这些路径存在的唯一原因，是该转发让这个后端成为进程内第二个执行 flush 的组件，面对的还是上游实验性（experimental）源码树中未见诸文档的 SDK 内部行为；不实现 `flush()` 时，批处理器就是唯一执行 flush 的组件，其 `scheduledDelayMillis`（已可由部署方经 `processor` passthrough 调优）决定导出节奏，`shutdown()` 的排空从构造上就是完整的。仅当某个部署提出 `scheduledDelayMillis` 无法满足的轮次边界延迟要求时才恢复此转发——且届时应调用留存的 `BatchLogRecordProcessor` 自身的 `forceFlush()`，绝不调用提供方那个带超时包装的版本。 diff --git a/.agents/notes/implemented/feature/2026-07-25-subagent-policy-inheritance.i18n.yaml b/.agents/notes/implemented/feature/2026-07-25-subagent-policy-inheritance.i18n.yaml index 8a4c76f227..ac6cdbcd01 100644 --- a/.agents/notes/implemented/feature/2026-07-25-subagent-policy-inheritance.i18n.yaml +++ b/.agents/notes/implemented/feature/2026-07-25-subagent-policy-inheritance.i18n.yaml @@ -2,5 +2,5 @@ # side as of the last confirmed-consistent state.

The activation-owner scope exists because ordinary Cordis owner effects unwind in reverse registration order, which cannot express the dynamic child graph. Manager initialization registers the private scope's structural disposer first and its drain disposer afterward, so reverse unwind invokes the drain before releasing that scope; merely registering a cleanup effect on the same scope as later Agent handles would allow structural handle disposal to bypass child-first ordering.

The Activation retains weak membership of that ancestry, so an intermediate Agent may leave the registry without hiding a still-live descendant from its host root. Each Activation installs one memoized disposal promise before cancellation or recursive callbacks, allowing scoped host shutdown, global manager unload, child release, and normal settlement to converge without double release. Cancellation propagates top-down before slow descendant cleanup; handle release remains child-first.

It wakes a parked parent and joins a running parent's nearest step boundary. When that parent is itself a continuable Activation, the send uses the manager's existing admission accounting so the parent cannot settle between synchronous inbox insertion and the admission microtask. Reports share the next-step FIFO with a later settlement notice, preserving their accepted causal order. - -Both modes frame one user-role message as `Background subagent reported:` followed by the exact `output`. The durable message source is `{ kind: 'subagent-report', senderSessionId: child.id }`. Normal Agent ordering governs concurrent sends; the subagent layer creates no second queue. - -### Acknowledgement and recovery - -Success means the exact live parent synchronously accepted the message. The context becomes reconstructable only when it reaches its normal log boundary; a next-step delivery has woken the parent, while quiet delivery may remain pending. The inbox message id remains separate from the returned stable message id. - -The first version provides no durable mailbox, idempotency key, delivery receipt, retry protocol, or exactly-once claim. A process failure can leave the caller uncertain, and retry after an unknown outcome may duplicate a report. The durable child transcript remains the recovery source when the parent is unavailable. - -### Composition and lifecycle - -The subagent seam adds `registerContinuableSetup(contribution): () => void`, backed by `SubagentActivationSetupRegistry`. Each synchronous contribution receives the unpublished child context and returns the disposer for its installation. The continuation manager first applies base child composition, then current contributions in registration order through the same setup closure used for fresh creation and cold resume. - -The registry owns registration, per-child installation records, setup rollback, child-scope cleanup, and immediate revocation. Applying a batch returns the Agent setup commit that revalidates provisioning after every setup await and immediately before Agent publication. A throwing or concurrently revoked contribution therefore rejects before either Agent or Session publication and rolls back the batch. New registrations affect a resident child only on its next Activation; removing a registration first closes it to new setup and then revokes every provisioning or resident installation immediately. Registration disposal and child-context disposal are idempotent and attempt every release before aggregating failures. - -This seam keeps the continuation manager unaware of tool names. The report package installs only `report` and its child-scoped guidance section; `@deepseek-ai/dsh-tool-subagent-control` independently installs parent-side `send_message` and `list_agents`. A deployment can install either direction, both, or neither. Providers remain data-only, durable descriptors do not snapshot report availability or delivery mode, and cold resume uses the deployment's current contributions and policy. - -### Snapshot coverage - -The ACP snapshot harness adds `waitForSubagentTurnEnd`, selecting the Nth harvested child by the same order as `session.N.jsonl`. It waits for a closed child turn containing a request header so a continuable child's earlier descriptor-seed turn cannot satisfy the boundary. This lets the assembled scenario wait for the child-side report without inventing a parent-visible signal. - -The authored snapshot starts a continuable child, executes the real scope-local `report` tool, and observes default next-step delivery before the manager's later settlement notice. A snapshot-only maintenance fence holds the parent until both messages are pending, proving next-step input is claimed before queued next-turn input when the parent resumes. It declares child pins `1`, so the otherwise non-global `report` schema and the child's own prompt are checked against `tool-schemas.1.expected.json` and `system-prompt.1.expected.md` while the root keeps the class pins. The generated tool catalog separately mints a child scope to include the same scope-local schema. - -## Alternatives considered - -### Automatically deliver every final answer - -Automatic delivery cannot represent zero reports, progress reports, or several selected updates. It also couples reporting to settlement and can duplicate content already reported explicitly. - -### Always wake the parent - -Waking on every report creates unsolicited turns and can cascade through nested subagents. Quiet delivery was chosen as the default on the assumption that the parent had another reason to read its context. [The report obligation](2026-08-06-continuable-child-report-obligation.md) supersedes that choice: a parked background coordinator has no such reason, so waking is the default and this paragraph now records why `quiet` still exists. - -### Let the child choose the delivery mode - -Giving the model a mode argument grants it control over scheduler pressure and makes behavior deployment-dependent. The child chooses content and timing; deployment config chooses whether that content wakes the parent. - -### Register a global tool - -A global `report` would advertise an unusable capability to roots, one-shot children, remote children, and agentless callers. Execution-time rejection would make schema visibility disagree with authority. - -### Combine both directions in the control package - -`send_message` and `report` have different audiences, scopes, configuration, and lifecycle. Independent packages let deployments grant either direction without implying the other. - -### Persist an offline parent mailbox - -Mutating or cold-resuming an absent parent requires a new durable addressing, authorization, conflict, acknowledgement, and replay protocol. Requiring a live direct parent keeps the first version on the existing Agent send path. - -### Reintroduce a Task or result promise - -A result-bearing wrapper makes one report or one turn appear terminal and recreates the lifetime mismatch that continuable Activations removed. Explicit repeatable sends need no intermediate execution object. - -### Validate setup after Agent creation - -A post-creation revocation check can reject the Activation only after the Agent and Session have been published. Disposing the returned handle removes the live objects but cannot delete persistence through the current seam, leaving a resumable child that the continuation manager said was never established. Returning an `AgentSetupCommit` instead lets the Agent factory perform the same mutable-state check synchronously at its publication boundary. - -## Consequences - -- A continuable in-process child exposes exactly one scope-local `report` schema only while the report package's contribution is installed; unrelated Agents never expose it. -- The tool returns the parent message's stable `MessageId`; its inbox occurrence is not a separate public identity. -- Only the exact resident child may report, and only to the exact live direct parent derived from durable lineage. The service has no recipient parameter or offline fallback. -- Next-step delivery is the validated default: it wakes an idle parent or extends a running parent's turn at the nearest step boundary. Quiet delivery never wakes an idle parent. -- Child cancellation or disposal after parent acceptance does not retract the report. Before acceptance, child disposal, drain, parent loss, or caller cancellation rejects the operation. -- Fresh and resumed Activations compose current setup contributions before publication. Grants wait for the next Activation; revocation is immediate for resident children. -- Unit coverage pins visibility, allow-list behavior, both delivery modes, stable message and sender identities, nested routing, invalid senders, absent parents, cancellation, drain, revocation races, and the absence of Jobs or implicit final reporting. -- The keyless assembled snapshot proves the real child tool, default next-step ordering before settlement, and durable parent framing. - -### Accepted risks - -The acceptance boundary is weaker than durable end-to-end delivery. A crash can leave the result ambiguous, and retries may duplicate reports. - -Next-step delivery can amplify model work when nested children report frequently. Reports waiting together share one step, and deployment ownership through `reportDelivery` bounds but does not remove that risk. - -Registry presence is the parent liveness signal. A host-owned parent whose `AgentHandle.dispose()` has started but has not yet unwound its scope can still accept and append a report that it will not act on in this process. Closing that gap requires an Agent-level disposal-start signal rather than subagent-layer inference. diff --git a/.agents/notes/implemented/feature/2026-07-30-continuable-subagent-report-tool.zh.md b/.agents/notes/implemented/feature/2026-07-30-continuable-subagent-report-tool.zh.md deleted file mode 100644 index 9cbf76a9f3..0000000000 --- a/.agents/notes/implemented/feature/2026-07-30-continuable-subagent-report-tool.zh.md +++ /dev/null @@ -1,118 +0,0 @@ -# Agent Note: 可继续 subagent 报告工具 - -Status: implemented - -[English](2026-07-30-continuable-subagent-report-tool.md) | 中文 - -## 问题 - -可继续的进程内 subagent 能够接收 parent 后续发来的消息、保留后代、结算并冷恢复，但基础生命周期无法让它们将选中内容发送给直接 parent。child 的完整输出已可从持久化会话中重建，因此缺失的能力是显式投递，而非结果存储。 - -如果将每条 assistant 最终消息都视为隐式结果，就会混淆轮次完成与报告。长期运行的 child 可能在某个轮次中无内容可报告，也可能在另一个轮次多次报告进展，而且报告后必须仍可继续工作。因此，接收方权限、静默投递与 next-step 投递、确认、持久性和重试行为都需要一份显式约定。 - -## 决策 - -新增可独立安装的 `@deepseek-ai/dsh-tool-subagent-report` 包。它会向每个可继续进程内 child Activation 贡献一个普通的面向模型 `report` 工具。机制本身接受一个轮次中调用零次或多次；child 会另行被要求在结束前调用一次（见[报告义务](2026-08-06-continuable-child-report-obligation.zh.md)）。调用成功既不会结束该轮次或结算 Activation，也不会阻止 parent 之后继续 follow-up；完成轮次也绝不会自动报告。 - -该功能是协作控制，不是承载结果的执行包装层。它不新增 Task、`SubagentRun`、结果 promise、Activation 状态、投递队列或回放路径。 - -### 面向模型的约定 - -`report` 只接受 `{ output: string }`，也只返回 `{ messageId: string }`。它不接受 child id、接收方 id 或投递模式。`exec.agent` 将工具调用绑定到发送报告的 child；服务从持久化 `parentSession` 中推导唯一接收方，调度则由部署配置决定。 - -`messageId` 是已接受进入 parent inbox 的用户角色消息所对应的稳定 `MessageId`。它不是已读回执、parent 日志确认、轮次完成回执或持久化 flush。 - -工具描述会明确报告操作在结束前必须执行、可重复、仅限直接 parent 且不会结束轮次。它还会警告：发送被接受后，后续 `tools/post-execute` 失败可能替换工具结果，因此工具结果失败时内容仍可能已经送达。没有幂等键时，更强的表述会诱导调用方在结果不明确的失败后重复重试。 - -该工具使用不带 location 的通用渲染，其确认中包含 `messageId`。作用域局部注册使呈现与执行保持一致：root、one-shot child、远程提供方、同级作用域和无 agent（智能体）执行既不能看到，也不能执行 `report`。它会在 child 的全局 `toolFilter` 之后安装，因此委派 allow-list 不会意外移除这条结构性返回通道；不需要返回通道的部署不安装该包。 - -### 服务权限 - -subagent seam 暴露 `ctx.subagents.reportFrom(child, content, { delivery, signal }): Promise`。确切的在线 child Agent 是发送方凭据。继续执行管理器只接受 `handle.agent === child` 的 Activation，从 child 的持久化 header 中推导其直接 parent，并要求该 id 在最终的同步授权与发送区间解析为一个在线 parent Agent。该 API 不接受由调用方选择的接收方、祖先或发送方字段。 - -root、one-shot child、伪造对象、陈旧 Agent 和同 id 替换对象都以 `UNAUTHORIZED` 失败。正在关闭的 child Activation 以 `ACTIVATION_CLOSING` 失败；管理器 drain 和接受前取消保留既有的生命周期错误。直接 parent 不存在或拒绝接受时，以 `PARENT_UNAVAILABLE` 和 `direct parent is not live;

The model could not discover current information unless a deployment supplied a custom overlay. Merely mounting the existing DeepSeek provider would not complete the WebUI path: the Models page stores `DEEPSEEK_API_KEY` through `ctx.credentials`, while the search provider froze only the process environment at plugin load, so a key entered or rotated in the running UI would not reach search. ## Decision -`apps/cli/config/base.cordis.yml` explicitly mounts `dsh-web` with `searchProvider: deepseek-official` and `fetchProvider: http`, `dsh-web-search-deepseek`, `dsh-web-fetch-http`, and `dsh-tool-web` with `fetch: false` and `searchTimeoutMs: 60000`.

[The report tool](2026-07-30-continuable-subagent-report-tool.md) gave that child a return channel and then presented it as one option among several: the schema said "call this zero or more times", nothing in the child's prompt asked it to call the tool at all, and the accepted default scheduling (`quiet`) added the report to a parked parent's next request without waking it. - -Each of those choices is defensible alone. Together they made the return channel unusable as a delegation contract. A child that finished its work, wrote its answer into its own transcript, and stopped left the parent with nothing; a child that did report reached a parent that had already parked and would not read the report until something unrelated woke it. External reports of parents busy-polling `list_agents`, re-sending messages to settled children, and abandoning `subagent` for `workflow` all reduce to the same missing guarantee. - -## Decision - -The return channel is an instruction the child receives, not a capability it may discover. The report package installs two scope-local registrations into every continuable in-process child, and one disposer revokes both: - -- the `report` tool, whose description now states that the child calls it once before finishing with a self-contained final result, and earlier for progress that changes what the parent should do next; -- a `tool:report` system-prompt section at first-party order 2900 carrying the same obligation in the child's own voice, so a child that never reads tool descriptions closely still receives it. - -`reportDelivery` defaults to `next-step`. An accepted report wakes a parked parent driver or joins a running parent's nearest step boundary, matching the instruction to report findings that change the parent's next action. `quiet` remains available for deployments that prefer unread reports over model-work amplification. The [report/settlement ordering decision](../bug-fix/2026-08-17-subagent-report-settlement-ordering.md) owns the scheduling rationale. - -### Why the section and the description both exist - -They address different failure modes. The tool description is read when the model is already considering `report`; the prompt section is read when it is deciding whether it is finished. The obligation belongs at both points because the failure this fixes — a child that simply stops — happens at the second one. - -The section is registered on the child's own scope, the same mechanism [child composition](../../../../packages/subagent/subagent/src/child-agent.ts) already uses for a shadowing persona, so the parent and every sibling see neither the tool nor the guidance. `installReportTool` rolls the section back if tool registration fails, and its returned disposer attempts both revocations before surfacing cleanup failures. - -### Instruction, not enforcement - -Nothing rejects a child that never reports. No runtime path inspects whether a report was sent, and `report` still accepts zero or many calls per turn. The change is model-facing wording plus a scheduling default; the service authority, acknowledgement, and recovery contracts are unchanged. - -That boundary is deliberate: prompt text can only reach a child that is still running its own loop. A child stopped by an error, a token ceiling, cancellation, or teardown never gets the chance to comply, which is why the runtime keeps its own account of settlement rather than trusting this instruction ([manager-owned settlement delivery](2026-08-06-manager-owned-subagent-settlement-delivery.md)). - -### Snapshot coverage - -The assembled ACP `subagent-report` scenario exercises the shipped default: the child reports while the parent is in maintenance, the later settlement notice queues behind it, and the resumed parent claims the next-step report before next-turn settlement. Because the child's scope composes a prompt the class pin cannot describe, the snapshot harness has `pinsChildSystemPrompts`, the exact counterpart of `pinsChildToolSchemas`: it moves one child fixture's prompt into `system-prompt..expected.md`, leaves every other request-header field to the class pin, requires the sidecar exactly when declared, and rejects a sidecar identical to that class pin so a redundant copy cannot drift. - -## Alternatives considered - -**Keep `quiet` as the default and rely on the prompt alone.** This was the shipped position, and it supersedes nothing on its own: a report the parent never reads is indistinguishable from a report never sent. The [report-tool note's](2026-07-30-continuable-subagent-report-tool.md) rejection of always-waking assumed the parent had another reason to look at its context; a parked background coordinator does not. Turn amplification is the real cost, and it is now the reason `quiet` still exists rather than the reason it is the default. - -**Let the child choose the delivery mode per call.** Unchanged from the original rejection: the model would own scheduler pressure, and behavior would vary per call rather than per deployment. - -**Put the obligation only in the tool description.** A description is read while choosing among tools. The child this change targets is not choosing a tool; it believes it is done. Prompt guidance is the surface that reaches that decision. - -**Enforce the obligation at settlement by rejecting a silent child.** There is nothing to reject: by the time settlement is observable the child's loop is over, and failing its teardown would destroy work rather than deliver it. Delivering the terminal facts unconditionally from the runtime is the answer to that case, and it belongs to the continuation manager, not to this package. - -## Consequences - -- Every continuable in-process child with this package loaded carries one extra prompt section and a longer `report` description in every request; no other Agent's request changes. -- The default deployment wakes the parent once per accepted report. A nested tree that reports frequently consumes extra parent requests, while reports waiting together share one step; `quiet` is the documented escape. -- `installReportTool` requires `ctx.systemPrompt` in the child scope, so the package declares `systemPrompt` in `inject` and fails at load rather than at the next child materialization. -- Unit coverage pins the new default, two load-bearing instruction phrases, the section's child-only scope against both the parent and a sibling, and rollback or revocation of both registrations. -- Three assembled ACP scenarios with continuable children pin the complete instruction text through the new sidecar; a future change to any child-scoped section fails those scenarios instead of passing silently. - -### Accepted risks - -Next-step delivery by default amplifies model work in deep trees.

Both questions are answered here: the credential seam is consulted before the process environment, and file existence is checked against the host process's filesystem with `~` expanded.

Source or transaction failure commits nothing and the next search retries. ### Schema ownership diff --git a/packages/session-query/session-query-sqlite/README.zh.md b/packages/session-query/session-query-sqlite/README.zh.md index cdbc10c53b..f6ef419293 100644 --- a/packages/session-query/session-query-sqlite/README.zh.md +++ b/packages/session-query/session-query-sqlite/README.zh.md @@ -101,7 +101,7 @@ kind: "package-reference" ### 索引生命周期 -持久化 FTS 行存放在专用派生数据库中并跨重启保留；实时会话使用连接本地 TEMP 表，遮蔽同一会话的持久化基库，并在实时所有者脱离后再次显示基库。每次搜索执行一次串行化观察：列出持久化快照、把逐会话修订与已索引行比较、只检查新增或已更改日志、提取语义文档，并在运行查询前于一个事务中提交对账。重复查询与不变的重新打开不会检查任何内容；切换存储或观察到新增、已更改、已删除或经外部修复的来源时，会在下次稳定观察时对账。来源或事务失败不提交任何内容，下一次搜索重试。 +持久化 FTS 行存放在专用派生数据库中并跨重启保留；实时会话使用连接本地 TEMP 表，遮蔽同一会话的持久化基库，并在实时所有者脱离后再次显示基库。两类表都在数字 `seed_length` 中保留精确继承切点；重建的 header 只公开 `isSeeded`，而切点参与实时 fingerprint 与持久来源修订。每次搜索执行一次串行化观察：列出持久化快照、把逐会话修订与已索引行比较、只检查新增或已更改日志、提取语义文档，并在运行查询前于一个事务中提交对账。重复查询与不变的重新打开不会检查任何内容；切换存储或观察到新增、已更改、已删除或经外部修复的来源时，会在下次稳定观察时对账。来源或事务失败不提交任何内容，下一次搜索重试。 ### Schema 归属 diff --git a/packages/session-query/session-query-sqlite/src/index.ts b/packages/session-query/session-query-sqlite/src/index.ts index f7e4ce043d..4722557a65 100644 --- a/packages/session-query/session-query-sqlite/src/index.ts +++ b/packages/session-query/session-query-sqlite/src/index.ts @@ -8,7 +8,14 @@ import { createHash, randomUUID } from 'node:crypto' import type { DatabaseSync } from 'node:sqlite' import { Context, Service, type Fiber } from '@deepseek-ai/cordis' import z from '@deepseek-ai/schemastery' -import type { Session, SessionEvent, SessionHeader, SessionId } from '@deepseek-ai/dsh-session' +import { SessionSeq } from '@deepseek-ai/dsh-session' +import type { + Session, + SessionEvent, + SessionHeader, + SessionId, + SessionLogOffset, +} from '@deepseek-ai/dsh-session' import type SessionPersistence from '@deepseek-ai/dsh-session-persistence' import type { SessionPersistenceRevision, @@ -126,6 +133,7 @@ interface ResolvedConfig { interface ObservedSession { header: SessionHeader + inheritedEventCount: SessionLogOffset documents: SessionEventSearchDocument[] fingerprint: string } @@ -508,7 +516,11 @@ export class SqliteSessionQueryEngine extends SessionQueryEngine { const loaded = await persistence.inspect(entry.header.id, signal) assertNotAborted(signal) assertSessionHeadersCompatible(entry.header, loaded.meta) -

Ordinary `create` remains lazy; a lifecycle frontend calls `ensureMaterialized` only when an empty session must itself appear in durable listing without inventing an event. `load` returns an immutable balanced log and commits any needed crash recovery; `inspect` reads the same view without committing recovery. Consumers that resume from a watermark can read only the events at or past a sequence number, and a session's artifact location (`locate`) resolves without filesystem I/O. +`append` resolves only after the batch is durable, so a resolved write survives an OS crash or power loss. Ordinary `create(meta, inheritedEventCount)` remains lazy; `meta.isSeeded: true` requires the sibling exact cut, while unseeded metadata may omit it and rejects a nonzero value. The first materializing batch for a seeded session must reach the complete inherited prefix, so storage never exposes metadata whose cut exceeds its log. A lifecycle frontend calls `ensureMaterialized` only when an empty session must itself appear in durable listing without inventing an event. `load` returns an immutable balanced log and commits any needed crash recovery; `inspect` reads the same complete view without committing recovery. `readFrom` accepts a `SessionLogOffset` and returns a detached `SessionEventSuffix` carrying that `fromSeq`, the unchanged inherited cut, and only stored events at or after the cut. A session's artifact location (`locate`) resolves without filesystem I/O. ### Resuming and crash recovery -Resume is `load` plus session preparation: the stored log comes back with its header lineage intact, so a resumed agent sees the same history and composition. A session that crashed mid-turn reloads with its interrupted final turn preserved and balanced: `load` appends synthetic `tool/result` and `turn/end {interrupted}` closers for unanswered calls instead of dropping the events — a single turn can be large, and those events were durably written before the crash. Only a never-fully-written torn tail fragment is discarded. +Resume is `load` plus session preparation: the stored log comes back with its header lineage and exact inherited cut intact, so ownership checks do not infer the cut from a marker or the full restore length.

**No pagination or deletion** — the complete stably ordered set is returned, and persisted children remain listed for as long as their sessions remain in persistence; a service-level bound or delete operation is a later product decision. diff --git a/packages/subagent/tool-subagent-control/README.zh.md b/packages/subagent/tool-subagent-control/README.zh.md index 1ba0379aeb..5a22f40b46 100644 --- a/packages/subagent/tool-subagent-control/README.zh.md +++ b/packages/subagent/tool-subagent-control/README.zh.md @@ -9,7 +9,7 @@ kind: "package-reference" ## 概述 -`dsh-tool-subagent-control` 为可继续子级添加全局控制工具：`send_message` 投递一条成为子级下一轮次的后续消息，`interrupt_agent` 停止子级当前轮次但保留其队列与后代，`list_agents`（来自可单独加载的 `list-agents` 插件）按持久化 id 与标签列出可继续子级。这些工具是全局的，因此任意数量的委派工具都不会产生重复。这些工具只覆盖父到子方向；子到父方向属于独立安装的 `dsh-tool-subagent-report`。是否加载这些工具不会决定委派工具是否启动可继续工作。 +`dsh-tool-subagent-control` 为可继续子级添加全局控制工具：`send_message` 在直接 parent 与 child 之间 steer，`interrupt_agent` 停止 child 当前轮次但保留其 inbox 与后代，`list_agents`（来自可单独加载的 `list-agents` 插件）按持久化 id 与标签列出可继续 child。parent 与可继续 child 继承相同的 `send_message` 定义和顺序，因此模型通信不会增加 child 专属工具 schema。是否加载这些工具不会决定委派工具是否启动可继续工作。 ## 目录 @@ -46,7 +46,7 @@ kind: "package-reference" ### send_message -发送一条消息，使之成为子级的下一 FIFO 轮次：正在工作的子级会先完成其当前轮次，因此消息无法重定向已经进行的工作。调用只返回接受结果（被接受消息的稳定 `messageId`），绝不返回子级的回复——通过其 id 查看子级 transcript（文本记录）才是它完成了哪些工作的真源。失败——未授权或未知子级、缺少描述符而无法恢复的子级，或准入被拒——会明确说明消息未送达。 +向 `agent_id` 指定的 Agent 发送消息：任何确切在线 Agent 都可以指定自己的直接可继续 child，而驻留的可继续 child 还可以指定自己的直接 parent。正在工作的目标通过 Steer 在最近的 step 边界接收消息；空闲目标会启动一个轮次，冷状态的直接 child 会通过继续执行生命周期恢复。调用只返回接受结果（被接受消息的稳定 `messageId`），绝不返回回复。失败——不受支持的目标、不可用的 parent、未知 child、缺少描述符而无法恢复的 child，或准入被拒——会明确说明消息未送达。 ### interrupt_agent @@ -68,11 +68,11 @@ kind: "package-reference" ### 设计理念 -`ctx.subagents.followup()`、`interrupt()` 与列表投影之上的轻量适配器；工具不执行任何生命周期路由。驻留、冷恢复与中断授权归服务所有，工具把确切在线的调用 agent（`exec.agent`）作为服务对照目标已记录 lineage 校验的权限凭据传入。 +`ctx.subagents.sendMessage()`、`interrupt()` 与列表投影之上的轻量适配器；工具不执行任何生命周期路由。驻留、冷恢复与授权归服务所有，工具把确切在线的调用 Agent（`exec.agent`）同时作为 sender 与权限凭据传入。 ### 投递与信号所有权 -工具转发其执行信号，该信号只在 inbox 接受之前掌管准入。子级一旦接受消息，已接受的轮次便无法再通过本工具取消。每条消息都记录协调者来源 `{ kind: 'coordinator', senderSessionId: parent.id }`；服务会保留该来源，但绝不将其视为权限。 +工具转发其执行信号，该信号只在 inbox 接受之前掌管准入。目标一旦接受消息，该消息便无法再通过本工具取消。每条消息都以 `Agent sent a message:` 作为前缀，并记录 `{ kind: 'agent-message', form: 'relay', senderSessionId: sender.id }`；该来源信息由服务推导，且绝不被视为权限。 ### 列表投影 @@ -97,7 +97,6 @@ kind: "package-reference" -

The tool and its guidance exist only inside those children — roots, one-shot subagents, remote providers, and sibling scopes never see them. Accepted reports reach the parent as ordinary parent messages, framed as `Background subagent reported:`. Continuable mode depends on neither this package nor the control package; this one owns only the child-to-parent direction. - -## Table of Contents - -- [Use this package](#use-this-package) -- [Understand the implementation](#understand-the-implementation) -- [Further Exploration](#further-exploration) -- [Model Experience](#model-experience) -- [Known Limitations and Deferred Work](#known-limitations-and-deferred-work) -- [Dev Note](#dev-note) - ------ - - -## Use this package - -Mount this package in a composition with continuable in-process children whose findings the parent should see before they finish.

The instruction is guidance, not enforcement: a child may call zero or many times in one turn, and finishing a turn never reports automatically. A successful call neither ends the turn nor settles the child's Activation. - -### What the parent sees - -An accepted report becomes one user-role parent message framed as `Background subagent reported:` followed by the child's exact output, with a durable source naming the child. `next-step` delivery wakes an idle parent or joins a running parent's nearest step boundary; `quiet` delivery adds the same context without waking the parent. The tool takes no recipient: the service derives the sole recipient from the child's durable `parentSession`. - -### Scope and direction - -The report tool deliberately survives the child's global `toolFilter`: a delegation allow-list cannot remove the only return channel. A deployment that requires a child with no return channel omits this package. The parent-to-child direction remains the independently installed control package, and continuable mode depends on neither package. - ------ - - -## Understand the implementation - -
-Implementation internals — click to expand - -This section explains how the tool is installed and scheduled; the observable behavior is covered in [Use this package](#use-this-package). - -### Design concept - -The package registers a continuable-child setup contribution rather than a global tool, so the tool and its guidance are installed inside each child's unpublished scope and vanish with it. The same registrations are ordinary child-scoped contributions, so an expert `system-prompt/assemble` listener could replace them and would then own preserving the reporting protocol for that child. - -### Delivery scheduling - -`next-step` uses `parent.steer()`: a running parent receives the report at its nearest safe step boundary, an idle parent starts a turn, and reports accepted in sequence share the next-step FIFO. `quiet` uses `parent.inject()`, adding the same next-step context without waking a parked parent. Both are deployment policy: the model-facing schema cannot select or override delivery per call. - -### Exported contribution - -`installReportTool(childCtx, ctx, delivery)` installs the tool and guidance into a minted child scope and returns one disposer revoking both. The generated tool catalog uses this path because the global registry cannot expose a scope-local schema; production composition still enters through `apply()`. - -### Source map - -| File | Role | -|---|---| -| [`src/index.ts`](src/index.ts) | Continuable-child setup: `installReportTool`, `Config`, delivery resolution | -| — | No runtime invariant companion is published; this adapter has no independent lifecycle stream; sender authorization and delivery relations belong to the subagent service. | - -
- ------ - - -## Further Exploration - -Read these pages when the package-level contract is not enough; they move from the report channel to the continuation service behind it and the parent-facing tools. - -- [Subagent subsystem](../../../docs/subsystems/subagent.md) — continuable children, activations, and the `reportFrom`/`reportDelivery` contract. -- [dsh-tool-subagent-control](../tool-subagent-control/README.md) — the parent-to-child control tools. -- [dsh-tool-subagent](../tool-subagent/README.md) — the delegation tool that starts continuable children. -- [Generated tool catalog](../../../docs/tool-catalog.md#deepseek-aidsh-tool-subagent-report) — the `report` schema. -- [Generated configuration catalog](../../../docs/config-catalog.md#deepseek-aidsh-tool-subagent-report) — every accepted config field. - ------ - - -## Model Experience - -### Tool schema - -#### What the model sees - -The generated [`report` schema](../../../docs/tool-catalog.md#deepseek-aidsh-tool-subagent-report): one required `output` string. Its description states that the child must report once before finishing, that reporting reaches only the Agent that started the child, and that it does not end the turn. It carries no recipient or delivery-mode parameter. The separate `tool:report` prompt section repeats the obligation outside the schema. - -#### Token effect - -Fixed schema and prompt-section cost per continuable-child request, and none in any other Agent's requests. - -#### KV Cache effect - -Prefix-stable within a child; neither the schema nor the section changes at runtime. Removing the package revokes both from resident children, which changes their next request prefix. - -### Report result - -#### What the model sees - -`report accepted by the agent that started you as message ` on acceptance; the canonical output carries the stable `messageId`. A failure from an unauthorized sender, an unavailable parent, or a closing lifecycle is an errored result. The description says a failed call may still have arrived, because a later `tools/post-execute` failure can replace the result after `reportFrom()` accepted the message. - -#### Token effect - -One short acknowledgement per call in the reporting child. The reported content is additionally billed to the parent: next-step delivery joins the next request in an open parent turn or starts a turn for an idle parent, while quiet delivery waits for another input to wake the parent. - -#### KV Cache effect - -Append-only in the child. In the parent, the framed report follows existing history and preserves the reusable prefix. - -### Parent-visible report - -#### What the model sees - -One user-role parent message framed as `Background subagent reported:` followed by the child's exact `output`, with a durable source `{ kind: 'subagent-report', senderSessionId: }` that names the child. - -#### Token effect - -The child's complete `output` plus the one-line frame, uncapped by this package. - -#### KV Cache effect - -Append-only; the report follows the parent's reusable request prefix. Next-step delivery wakes the parent and may extend its open turn, while quiet delivery does not wake it. - -## Known Limitations and Deferred Work - - - - -These limits define what an accepted report does and does not guarantee; they are current package constraints. - -- **A parent whose host-owned disposal already started can still accept** — `AgentHandle.dispose()` cancels, awaits quiescence, and only then unwinds the scope and leaves the registry; it exposes no signal for "disposal started." A report accepted in that window is appended to the parent's transcript, but that parent will not act on it in this process. A continuation-manager-owned parent rejects forest teardown through the manager's admission boundary. -- **Acceptance is weaker than durable delivery** — there is no durable mailbox, idempotency key, delivery receipt, retry protocol, or exactly-once claim. A process failure after one side recorded acceptance leaves the outcome ambiguous, and an external retry may duplicate the report. -- **A staged quiet report is not immediately reconstructable** — acceptance returns its stable `MessageId`, but the parent Session reconstructs the framed content only after pending context reaches its ordinary log boundary. -- **Granting waits for the next Activation; revocation is immediate** — installing this package after a child becomes resident grants `report` and its guidance only on that child's next Activation, while removing the package revokes both from resident children immediately. -- **Nested reporting reaches exactly one edge upward** — a grandchild reports to its direct child parent, never to the top-level coordinator, which must explicitly report a derived update later. -- **No rate limiting** — the default `next-step` mode can amplify model work when nested children report frequently, although reports waiting together share one step; a deployment that accepts unread reports over that amplification selects `quiet`. - - -### Dev Note - -
