/**
 * The prepare → bind → activate lifecycle for adopting an existing chat root.

 * Stock startup publishes a session's readiness immediately, so the running
 * chat daemon surfaces the session and creates its own root before an operator

 * instead: readiness stays withheld while the provider applies its one root
 * claim. The SessionRouter owns endpoint authority and activation; this module
 * only proves that the provider mapping authorizes readiness publication.
 *
 * Nothing here mutates a mapping. The gate only reads the daemon-owned store to
 * prove a binding exists for the exact session and endpoint generation.
