+# Agent Note: Incubate Agent Teams as private experimental packages
+
+Status: implemented
+
+English | [中文](2026-08-18-experimental-agent-teams-packages.zh.md)
+
+## Problem
+
+Agent Teams needs the real Session log, subagent lifecycle, tools, examples, snapshots, and repository checks while its service and tool contracts continue to change. Placing those packages in a product-role group makes them members of the dsh release family and gives them the same publication expectation as stable packages.
+
+An experimental directory without a current package previously imposed placement, dependency, promotion, and release rules on no consumer. Agent Teams supplies the concrete consumer, but the directory needs mechanical release exclusion and dependency isolation rather than a documentation-only status.
+
+## Decision
+
+`packages/experimental/team` and `packages/experimental/tool-team` are private workspace packages. Their npm names remain `@deepseek-ai/dsh-team` and `@deepseek-ai/dsh-tool-team`, so promotion changes paths and release metadata without renaming imports.
+
+The dsh release family and local baseline publisher exclude every manifest below `packages/experimental/`. Workspace constraints require each experimental package to set `private: true` and omit `publishConfig`. The same top-level check rejects `dependencies`, `optionalDependencies`, and `peerDependencies` from release packages, release apps, or the Python runtime to an experimental package. Experimental packages may depend on release packages and each other; tests may use them through `devDependencies`, and examples may load them explicitly.
+
+The generic caller-reserved continuable child identity and selective direct-child drain remain in the stable Subagent service. They own Subagent identity and Activation lifecycle without importing or naming Agent Teams; the experimental Team service consumes them in the permitted direction.
+
+Experimental status changes publication and compatibility expectations only. The packages retain the repository's ordinary documentation, invariant, lifecycle, security, unit, real-composition, and snapshot requirements. Promotion requires review of the public contracts, limitations, test evidence, release payload, runtime dependents, and a named owner accepting stable-package obligations.
+
+## Alternatives considered
+
+**Keep Agent Teams in a product-role group and describe it as opt-in.** Opt-in composition controls model behavior but does not exclude packages from publication or prevent stable packages from taking runtime dependencies on them.
+
+**Reserve an empty experimental group.** A directory without a current package has no owner or release mechanism to test. The group exists only while concrete packages need its enforced treatment.
+
+**Move the Subagent prerequisites into the experimental directory.** Child identity allocation and Activation teardown belong to the Subagent owner and contain no Team-specific contract. Moving or duplicating them would invert the dependency or split one lifecycle across packages.
+
+**Publish experimental packages under different npm names.** Experimental suffixes would make promotion rename every import and configuration row without strengthening release exclusion; private manifests and release-family filtering enforce the actual requirement.
+
+## Consequences
+
+Agent Teams can use the full repository graph and quality checks without entering official tarballs or becoming a supported runtime dependency. A release package cannot expose Team until the Team packages are promoted, so CLI and Web experiments use explicit example or experimental compositions instead of the shipped base bundles.
+
+The product-role grouping is less direct while the packages incubate, and promotion creates path churn. Keeping npm names stable limits that churn to repository paths, metadata, documentation, and composition.

+# Agent Note: 将 Agent Teams 作为私有实验性包孵化
+
+Status: implemented
+
+[English](2026-08-18-experimental-agent-teams-packages.md) | 中文
+
+## 问题
+
+Agent Teams 的服务与工具约定仍在变化，但它需要使用真实 Session 日志、subagent 生命周期、工具、示例、快照和仓库检查。把这些包放在产品职责组会使其成为 dsh 发布系列成员，并获得与稳定包相同的发布预期。
+
+没有实际包的 experimental 目录曾经让没有消费方的放置、依赖、promotion 和发布规则长期存在。Agent Teams 提供了具体消费方，但该目录需要机械强制的发布排除与依赖隔离，不能只用文档标记状态。
+
+## 决策
+
+`packages/experimental/team` 与 `packages/experimental/tool-team` 是私有 workspace 包。其 npm 名仍为 `@deepseek-ai/dsh-team` 与 `@deepseek-ai/dsh-tool-team`，因此 promotion 只需修改路径与发布元数据，无需重命名 import。
+
+dsh 发布系列与本地 baseline 发布器均排除 `packages/experimental/` 下的所有 manifest。workspace 约束要求每个实验性包设置 `private: true` 并省略 `publishConfig`。同一个顶层检查会拒绝发布包、发布 app 或 Python runtime 通过 `dependencies`、`optionalDependencies` 或 `peerDependencies` 依赖实验性包。实验性包可以依赖发布包和其他实验性包；测试可以通过 `devDependencies` 使用它们，示例可以显式加载它们。
+
+通用的调用方预留 continuable child 身份和精确 direct-child drain 仍属于稳定 Subagent 服务。它们负责 Subagent 身份与 Activation 生命周期，不 import 或命名 Agent Teams；实验性 Team 服务沿允许的方向消费这些能力。
+
+实验性状态只改变发布与兼容性预期。这些包仍须满足仓库的一般文档、不变式、生命周期、安全、单元测试、真实组合测试和快照要求。promotion 前必须评审公开约定、限制、测试证据、发布 payload、运行时依赖方，并由一名具名 owner 接受稳定包义务。
+
+## 曾考虑的替代方案
+
+**把 Agent Teams 留在产品职责组，并标为显式启用。** 显式启用的组合可以控制模型行为，但不会阻止包发布，也不能阻止稳定包对其建立运行时依赖。
+
+**预留空的 experimental 组。** 没有实际包的目录没有 owner，也没有可供测试的发布机制。只有具体包需要这套强制处理时，该组才存在。
+
+**把 Subagent 前置能力移入 experimental 目录。** child 身份分配与 Activation teardown 属于 Subagent owner，且不包含 Team 专用约定。移动或复制这些能力会反转依赖方向，或把同一个生命周期拆到多个包中。
+
+**使用不同的 npm 名发布实验性包。** experimental 后缀会让 promotion 重命名所有 import 与配置项，却不能加强发布排除；私有 manifest 与发布系列过滤已经强制执行实际要求。
+
+## 后果
+
+Agent Teams 可以使用完整仓库依赖图与质量检查，而不进入正式 tarball，也不会成为受支持的运行时依赖。在 Team 包 promotion 前，发布包不能暴露 Team，因此 CLI 和 Web 实验使用显式示例或实验性组合，而不是已发布的基础组合包。
+
+孵化期间的产品职责分组不够直接，promotion 也会产生路径改动。保持 npm 名稳定后，改动范围仅包括仓库路径、元数据、文档和组合。

 Every ordinary runtime root is the implicit Lead of a Team identified by that root's `SessionId`. The Team has no creation event: its Lead pseudo-row exists by identity, while durable state begins with the first member, message, or task event. A roster is flat and contains at most the configured number of immutable lowercase-kebab-case names. Each teammate is a continuable direct child with a reserved Session id; only the Lead creates or interrupts teammates. Ordinary provider-owned subagents outside the roster are not Team members, and an ordinary fork is a new root whose inherited Team records are excluded by their ancestor `TeamId`.
 
-The implementation is split into `@deepseek-ai/dsh-team`, which owns `ctx.teams` and durable semantics, and `@deepseek-ai/dsh-tool-team`, which owns scoped schemas and model guidance. Every Team tool declares its complete result schema and renders that value as compact JSON, so the compiler checks each `execute` against what the model is promised and no result spends tokens on indentation. Deployments mount both plugins explicitly and may disable legacy continuable controls with the same model-visible names. The explicit delegation policy permits Team creation only when the user asks for Agent Teams or teammates.

-# Agent Note: Remove the empty experimental package group
-
-Status: implemented
-
-English | [中文](2026-08-11-remove-empty-experimental-package-group.zh.md)
-
-## Problem
-
-The package hierarchy reserves `packages/experimental/` for prototypes and internal-only plugins, but no package has used the group. The empty group adds placement, dependency, promotion, and release rules without a current package or release mechanism that needs them.
-
-The original group aimed to let the team share prototypes against the real plugin graph without implying product support. That need remains possible, but it does not justify a permanent repository category before a concrete package exists.
-
-## Decision
-
-The package hierarchy has no reserved experimental or internal-only group. Packages continue to live in groups selected for their current product role.
-
-A concrete package that needs different release, stability, or dependency treatment requires a decision based on its actual consumers and release mechanism. That decision may reintroduce a dedicated group when it can also define and enforce the exclusion rules.
-
-This note consolidates and supersedes the experimental-package-group decision, whose active triplet is removed with the empty directory.
-
-## Alternatives considered
-
-**Keep the empty group.** It provides an obvious future incubation location, but it also keeps repository rules with no current owner, package, or enforcement mechanism.
-
-**Move the experimental rules into the general package instructions.** This preserves the policy without an empty directory, but makes every package change carry rules for a hypothetical package class.
-
-**Put concrete experimental packages in product-role groups with README labels.** This preserves product-role colocation, but labels alone cannot enforce release and runtime-dependency rules. A future package can evaluate this option against its actual release mechanism.
-
-**Treat every package as experimental until the first tagged release.** This applies a broad temporary status without providing durable treatment for packages that remain experimental after releases begin.
-
-**Require prototypes to stay outside the repository.** This would lose access to the real plugin graph, examples, snapshots, and lifecycle checks. Removing the reserved group does not impose that restriction; a concrete prototype can establish the placement it needs.
-
-## Consequences
-
-The hierarchy loses an unused group and its special release and dependency policy. It also gives up a predeclared location for team discovery and a ready-made promotion path.
-
-The first package that needs experimental or internal-only treatment must define where it lives, how releases exclude it, which runtime dependencies are allowed, and what condition promotes or removes it. A dedicated group can return when those rules have a current consumer and enforceable mechanism.

-# Agent Note: 移除空的实验性包分组
-
-Status: implemented
-
-[English](2026-08-11-remove-empty-experimental-package-group.md) | 中文
-
-## 问题
-
-包层级结构预留 `packages/experimental/` 用于原型和内部专用插件，但从未有包使用该分组。这个空分组添加了放置、依赖、提升和发布规则，却没有需要这些规则的现有包或发布机制。
-
-原分组旨在让团队基于真实插件图共享原型，同时不暗示产品会提供支持。这项需求将来可能出现，但在具体包出现前，不足以支持一个永久的仓库类别。
-
-## 决策
-
-包层级结构不再预留实验性或内部专用分组。包继续按照当前产品职责放入对应分组。
-
-如果具体包需要不同的发布、稳定性或依赖处理，必须根据其实际消费方和发布机制做出决策。只要该决策同时定义并强制执行排除规则，就可以重新引入专用分组。
-
-本 Agent Note 整合并取代实验性包分组决策；该旧决策的活跃三文件组随空目录一并移除。
-
-## 考虑过的替代方案
-
-**保留空分组。** 它为未来孵化工作提供明确位置，但也会保留没有当前负责人、包或强制执行机制的仓库规则。
-
-**将实验性规则移入通用包指令。** 这可以在不保留空目录的情况下延续政策，但会让每次包变更都携带针对假设包类别的规则。
-
-**将具体实验性包放入产品职责分组，并用 README 标注。** 这会保持产品职责共置，但仅靠标注无法强制执行发布和运行时依赖规则。未来的包可以根据实际发布机制评估此选项。
-
-**在首个带标签的版本发布前，将每个包都视为实验性。** 这会施加宽泛的临时状态，却无法为发布开始后仍处于实验状态的包提供持久处理方式。
-
-**要求原型留在仓库外。** 这会失去真实插件图、示例、快照和生命周期检查。移除预留分组并不施加这项限制；具体原型可以建立自身所需的放置规则。
-
-## 后果
-
-包层级结构移除了未使用的分组及其特殊发布和依赖政策，同时也放弃了预先声明的团队发现位置和现成的提升路径。
-
-第一个需要实验性或内部专用处理的包必须定义其存放位置、发布版本如何排除它、允许哪些运行时依赖，以及包在何种条件下获得提升或被移除。当这些规则具有当前消费方和可强制执行的机制时，可以恢复专用分组。

+# AGENTS.md — Experimental packages
+
+These rules supplement the [package rules](../AGENTS.md). The [experimental Agent Teams package decision](../../.agents/notes/implemented/architecture/2026-08-18-experimental-agent-teams-packages.md) owns the rationale.
+
+- A package belongs here only when its complete public contract is experimental or internal-only. An experimental option inside a release package stays with its owning product role.
+- Every package here sets `private: true` and omits `publishConfig`; the dsh release family excludes this directory.
+- Release packages and apps must not name packages here in `dependencies`, `optionalDependencies`, or `peerDependencies`. Experimental packages may depend on release packages and each other. Tests may use experimental packages through `devDependencies`; examples may load them explicitly.
+- Experimental status does not relax engineering, security, documentation, lifecycle, testing, invariant, or snapshot requirements.
+- Promotion moves a package to its product-role group without renaming its `@deepseek-ai/dsh-*` package. Review its public contract, limitations, test evidence, release payload, runtime dependents, and named stable owner before promotion.

 `waitForChange()` waits for one roster, task, mailbox, or live-status edge that occurs after registration, for 10 seconds through one hour; it reports only whether the wait timed out and does not replay a change that already happened. Runtime disposal releases current waits and makes later waits return immediately without a timeout. Callers re-read authoritative state after wakeup or timeout. Cancellation preserves an Error reason or reports a non-Error reason through `TEAM_WAIT_ABORTED` with structural inspection instead of object coercion. `interrupt()` is Lead-only and delegates to the continuable-subagent interrupt path, which cancels only a live teammate's current turn with `keepInbox`; it neither releases task ownership nor deletes durable mail.
 
-The separately published `./invariant` companion replays each candidate Team event against its committed Session prefix. Replay validates every current-version Team payload before it enters folded state, then rejects invalid member transitions, reused names, out-of-range numeric task ids, discontinuous task revisions, invalid task dependencies, duplicate queue/ack records, and acknowledgements with the wrong target before append. Session event `seq` and `time` own ordering and timing instead of duplicated snapshot timestamps.

 `waitForChange()` 可以等待注册后发生的下一条 roster、task、mailbox 或实时 status 边，时长范围为 10 秒到 1 小时；它只报告等待是否超时，也不会回放调用前已经发生的变化。运行时 dispose 会释放当前等待，并使后续等待不经超时立即返回。调用方需要在唤醒或超时后重新读取权威状态。取消会保留 Error reason；非 Error reason 则通过 `TEAM_WAIT_ABORTED` 以结构化检查结果报告，不再强制转成 object 字符串。`interrupt()` 仅限 Lead，并委托 continuable-subagent 的 interrupt 路径以 `keepInbox` 只取消 live teammate 的当前 turn；它既不释放任务 owner，也不删除持久 mail。
