 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.
 
-`ctx.subagents.resolveName()` returns the Session id for `lead` or a full name by reading only the catalogs along the path; any other text is returned unchanged as a Session id. Tools resolve before they call messaging, interruption, or Team assignment, and those operations authorize the resulting Session id. Resolution grants no authority. Runtime-authored text names agents by full name, while durable attribution such as `senderSessionId` and Team `ownerId` keeps Session ids. The [subagent runtime](../../../../packages/subagent/subagent/README.md#agent-names) owns the API contract and the [upgrade guide](../../../../docs/upgrade-guide/v0.2.2-alpha.2/subagent-names/guide.md) owns caller migration.

 This supersedes the rejection of "unique names as sibling-routing opt-in" and the statement that creation accepts no member name in [subagent teammates](2026-10-15-agent-teams-as-subagents.md), and the Session-id identity text in [required runtime-context identity](2026-10-13-team-identity-runtime-context.md). Their single-identity, Team, and runtime-context retention decisions remain active.
