- Backends register one stable `type` and return an unpublished `PtyBackendSession`; failed or cancelled setup must clean partial resources.
- Spawn cancellation preserves the caller's exact abort reason. Service disposal and owner loss remain distinct machine-routable failures after backend setup.
- Owner and service disposal abort unpublished setup through a service-owned signal and await backend settlement plus rollback before returning.
- `hasOwnerActivity(owner)` spans unpublished setup through final close, so lifecycle policy can fence the exact owner without a publication race.
- A successful spawn publishes one `PtySessionId`. The optional `name` is owner-local display metadata, never authority.
- One session accepts at most one live send operation. Reads and signals may observe it; another send fails until the operation settles.
