Remove the host-user continuation capability and the public residency query, then separate the seam's public event payloads from its internal lifecycle control interfaces. `followup()` now takes the exact live direct parent `Agent` instead of a `SubagentAuthority` union. No production adapter ever supplied user authority, so the `UserAuthorityGrant` brand token existed only to stop a forged discriminant from bypassing the direct-parent check — deleting the branch retires the token, its mint method, and that attack surface together. Narrowing `parent` from `Agent | undefined` to `Agent` removes three special cases, including the path where a parentless epoch dispatched its lifecycle events unscoped. Scoped-versus-global dispatch is now decided by the event, not by whether a caller happened to have a parent. `activationState()` had no caller; `ActivationState`, `ActivationObserver`, and `ContinuationHost` are package-private. New `src/lifecycle.ts` owns the contained emitter, the one-shot run observer, and the Activation observer, while `SubagentRunInfo`/`SubagentRunEndInfo` move to `src/types.ts` beside the other consumer-facing contracts. Those payloads are public API — dsh-jsonrpc, hooks-claude, and the package invariant all consume them — whereas the observer is a contract between two in-package collaborators, so they no longer share a home merely for both being lifecycle-shaped. The service keeps ownership of the scope carrier: `scopeTarget()` composes the service's own context filter, so a narrowed stand-in would silently change scope filtering. Also drops now-unused dsh-tasks-local and dsh-tool-tasks dev dependencies, and corrects the README claim that a pre-residency failure emits a terminal edge — that path only ever rethrew.
