fix(agent): commit mutable setup at publication
Agent setup may await while a mutable contribution registry changes. The previous subagent path validated and committed its provisioning batch inside the setup callback. A revocation queued after that callback returned therefore treated the installation as resident and released it, even though AgentLoop had not published the child yet. AgentLoop could then admit and announce a child whose required capability had already disappeared. Introduce AgentSetupCommit as the optional synchronous result of create and resume setup. AgentLoop now awaits setup, invokes that commit with no intervening asynchronous boundary, and only then enters the Session and Agent registries. A commit failure follows the existing private-transaction rollback, so neither identity is published and the caller can reuse the id. Keep continuable-subagent installations provisional until this publication commit. Contribution removal still releases every installation immediately, but now marks an unpublished batch invalid so its commit rejects with ACTIVATION_SETUP_REVOKED. Once the commit succeeds, later removal remains ordinary live revocation. Cover create and resume ordering, resume commit rejection and identity reuse, and an assembled microtask revocation that leaves only the parent Agent and Session. Update the public JSDoc, architecture flow, package contracts, current Agent Notes, Chinese counterparts, pairing records, and generated Cordis API to describe the new boundary. Validated with the four focused Agent/subagent test files (91 tests), the isolated assembled regression, targeted TypeScript project builds, generated Cordis API freshness, export JSDoc verification, scoped translation pairing, Markdown wrapping, and Mermaid parsing.

`ctx.agents.create()` and `resume()` build an unpublished session, scope, agent, and driver. They await `setup`, synchronously invoke its optional `AgentSetupCommit`, admit the final session and agent entries, announce them in order, start the loop, and only then return a handle. The commit lets mutable provisioning revalidate at the exact publication boundary after every setup await; a throw rolls the private transaction back before either identity is announced, while revocation after a successful commit is ordinary live teardown.

An optional creation signal cancels work only while create or resume is pending. After the promise resolves, the returned `AgentHandle` owns explicit disposal.

|
||||
If loading, setup, admission, or publication fails, the private transaction rolls back everything it prepared. Concurrent operations using the same caller-supplied live ID may both reach setup, but final registry entry admits only one; every loser rejects and cleans its private resources. Sequential reuse after awaited disposal remains valid.

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.

This seam keeps the continuation manager unaware of tool names. The report package installs only `report`; `@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.

|

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.

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.

The final setup-revocation check runs after `ctx.agents.create()` or `ctx.agents.resume()` returns, after lower-level Agent and Session publication. Revocation in this window rolls back the handle and prevents the subagent Activation start edge but may leave a persisted Session. Moving the cutoff before lower-level publication requires a future Agent-creation setup transaction seam.
