 Each new child has a name that is unique among its creator's children. The name is a field of the `subagent/catalog` entry that the creator already appends when it creates the child, using catalog payload version 3. Local and parent-delivered external creation write it; caller-delivered external runs enter no catalog and take no name. A name is 1–32 lower-case letters, digits, or hyphens starting with a letter, and is never `lead`. A 36-character UUID therefore never parses as a name. Omission selects the first free `agent-N`. An explicit name already held by a sibling fails with `DUPLICATE_AGENT_NAME`, and an invalid name fails with `INVALID_AGENT_NAME`.

-The creator reserves the name synchronously at admission, before startup awaits anything. The reservation lives in process memory beside the creator's committed catalog names and is released when the catalog entry commits or startup fails. No other write records the name.
+The creator reserves the name synchronously at admission, before startup awaits anything. The reservation lives in process memory beside the creator's committed catalog names and is released when the catalog entry commits or startup fails. Task assignment copies the immutable full name into optional `ownerName` beside `ownerId` in the same task event. Task reads use this saved value and fall back to `ownerId`, so display does not require catalog traversal.

 The root is always `lead`. A descendant's full name is the slash-separated path of names from the root without a `lead/` prefix, such as `reviewer/checker`. Sibling-unique segments make full names unique in the tree. A child whose catalog entry predates names, and every descendant below it, keeps its Session id as its name.

 每个新子级都有一个名称，在其创建者的子级之间唯一。名称是创建者在创建子级时本就会追加的 `subagent/catalog` 条目中的一个字段，使用第 3 版目录载荷。本地创建和父级投递的外部创建写入名称；调用方投递的外部执行不进入目录，也没有名称。名称由 1–32 个小写字母、数字或连字符组成，以字母开头，且绝不能是 `lead`。因此 36 字符的 UUID 永远不会被解析为名称。省略时选择第一个空闲的 `agent-N`。显式请求同级已持有的名称会以 `DUPLICATE_AGENT_NAME` 失败，无效名称以 `INVALID_AGENT_NAME` 失败。

+创建者在准入时、启动等待任何操作之前同步预留名称。预留保存在进程内存中，与创建者已提交的目录名称并列，并在目录条目提交或启动失败时释放。任务分配在同一个任务事件中，将不可变的完整名称复制到 `ownerId` 旁的可选 `ownerName`。任务读取使用此保存值，缺失时回退到 `ownerId`，因此展示无需遍历目录。

 根的名称始终为 `lead`。后代的完整名称是从根开始、以斜杠分隔的名称路径，不带 `lead/` 前缀，例如 `reviewer/checker`。同级唯一的各段使完整名称在整棵树中唯一。目录条目早于名称机制的子级及其下所有后代继续以 Session id 作为名称。

+
+<a id="compatibility"></a>
+## Compatibility
+
+Current readers accept existing task payloads without ownerName and display ownerId without rewriting or backfilling historical logs. New task records retain the same ownerId authorization and version 2 task semantics. Earlier Team projections use a strict task schema and reject records containing ownerName, retaining their last valid tasks and reporting a projection failure rather than silently misinterpreting ownership. Session format version remains unchanged. The agentTeam projection state version advances to 8 so version 6 and 7 checkpoints rebuild from events.
+
+<a id="verification"></a>
+## Verification
+
+Focused Agent Teams projection, task-board, tool, and JSONL/SQLite recovery tests pass. They cover saved root and nested owner names, clearing ownership, historical ID fallback, rejection of ownerName without ownerId, checkpoint rebuilds, and task reads and edits without descendant catalog queries.

+## 兼容性
+
+当前读取方接受没有 ownerName 的已有任务载荷，直接显示 ownerId，不改写或回填历史日志。新任务记录保留相同的 ownerId 授权和第 2 版任务语义。旧 Team 投影使用严格任务 schema，会拒绝包含 ownerName 的记录，保留最后的有效任务并报告投影失败，不会静默误读归属。Session 格式版本保持不变。agentTeam 投影状态版本升为 8，使第 6、7 版检查点从事件重建。
+
+<a id="verification"></a>
+## 验证
+
+聚焦的 Agent Teams 投影、任务板、工具及 JSONL/SQLite 恢复测试通过，覆盖保存的根与嵌套所有者名称、清除归属、历史 ID 回退、拒绝没有 ownerId 的 ownerName、检查点重建，以及不查询后代目录的任务读取和编辑。

 ## Change

-Each new subagent has a name that is unique among its creator's children and recorded in the creator's `subagent/catalog` entry. The root is `lead`; a descendant's full name is its path from the root, such as `reviewer/checker`. The [subagent runtime](../../../../packages/subagent/subagent/README.md#agent-names) defines the name rule. Children created before upgrading keep their Session ids as names. These changes affect scripts, Code-mode (PTC) programs, SDK callers, and recorded transcripts that call or parse these tools, and code that reads catalogs or constructs activations:
+Each new subagent has a name that is unique among its creator's children and recorded in the creator's `subagent/catalog` entry. The root is `lead`; a descendant's full name is its path from the root, such as `reviewer/checker`. The [subagent runtime](../../../../packages/subagent/subagent/README.md#agent-names) defines naming rules. Historical children keep their Session ids. Scripts, Code-mode (PTC), SDK callers, and transcripts must use these interfaces:

 - `send_message({ agent_id, message })` becomes `send_message({ agent, message })`, and `interrupt_agent({ agent_id })` becomes `interrupt_agent({ agent })`. `agent` accepts a name or a Session id. A call that still passes `agent_id` fails argument validation.
- `subagent`, `subagent_fork`, and `subagent_oar` accept an optional `name`. They return `started subagent <name>`, and their result is `{ kind: 'activation', subagentId, name }`.
+- `subagent`, `subagent_fork`, and `subagent_oar` accept an optional `name`. They return `started subagent <name>`, and their result is `{ kind: 'activation', name }`.
 - `list_agents` returns `{ name, status, description? }` rows instead of rows with `kind`, `id`, `label`, `parent`, `depth`, and `reason`. Unreadable branches report `corrupt`, `unsupported`, or `unavailable` as `status`. Text rows read `<name> [<status>] — <description>`.
- Team task results replace `ownerId` with `owner`, the owner's name. `team_task_list` and `team_task_update` accept a name as `owner`.
+- Team task results replace `ownerId` with `owner`, the owner's name. `team_task_list` and `team_task_update` accept a name as `owner`. To list tasks without an owner, use `unowned: true` instead of `owner: "unowned"`.
 - Local and parent-delivered external creation write `subagent/catalog` payload version 3. Releases before this one reject catalogs that contain it, so they cannot open Sessions that create subagents after upgrading. See the [persistence acknowledgement](../../../persistence-changes/2026-11-02-subagent-catalog-names.md).
 - `SubagentActivation` has a required `name` field, and `SubagentActivationSpec` accepts an optional `name`.

 6. Upgrade every process that opens the same Session store before creating subagents. Older releases cannot open Sessions that contain catalog payload version 3.
 7. To confirm the change, start a subagent with `name: "reviewer"` and check that the receipt reads `started subagent reviewer`, that `list_agents` lists `reviewer`, and that `send_message({ agent: "reviewer", message })` succeeds.

 ### Policy and tools

-One plugin registration provides a dynamic `team:policy` section and four conditional task tools. Each provider reads the caller’s root Session selection, including fork children. An unavailable root disables Team tools and guidance. Tree authority comes from `ctx.subagents.rootOf(agent)`; task owners remain Session ids in `ctx.agentTeams`. Owner arguments resolve through `ctx.subagents.resolveName()`, which grants no authority. Results replace `ownerId` with `owner`, read from the `path` of `ctx.subagents.listDescendants()` rows. `team_task_list` and `team_task_get` read names only when a returned task has an owner; `team_task_update` reads them before its change commits, so a failed read rejects the call before the task changes. Identity, discovery, communication, and waiting belong to [subagent controls](../../subagent/tool-subagent-control/README.md) and remain unchanged when Team mode switches. The subagent runtime delivers final results.
