setScopeParent could re-link any key from anywhere, leaving the blank-session-only recompose rule entirely to caller discipline. The relation now binds once — a second bind throws — and re-linking exists only on the ScopeParentBinding returned to the original binder, the private-capability shape the package conventions prescribe for a single-caller operation. The preset roster keeps each composed agent's binding in a WeakMap keyed by the agent, making it the sole authority that can move an agent between standing compositions; the blank-session contract itself stays with the gateway, which alone can see what a session logged.
preset/ — per-session agent composition
English | 中文
An agent preset is a directory holding one agent.cordis.yml. Mounting it under an agent's scope context gives that session its own tools and prompt sections while every other live session keeps its own, so one process can run several differently composed agents at once.

The composition split this group assumes: registries and cross-session facilities are process singletons and stay in the host composition, while a preset carries what one agent contributes to them. A preset that names a row publishing a process-global service is rejected at mount rather than allowed to collide with the next session.
