E.g. validation_failed, unauthorized, forbidden, not_found, conflict, session_quota_exceeded, home_in_use, home_not_provisioned, parent_app_disabled, profile_ineligible, profile_not_launchable_for_app, no_host_available, capacity_exhausted, restart_required, rate_limited, internal. Open string, not an enum: new codes are additive and an unknown one falls through to a client’s generic per-status branch.
Present on restart_required.
Steam library discovery Phase 3, ADDITIVE: present on home_in_use when the guard could name the CONFLICTING live session - the one already holding the home. It is here so the client can offer “go to your running session” with a link instead of a dead-end toast. OMITTED rather than empty when the conflict is known but the session is not, so a client branches on presence and never renders a link to nowhere. Load-bearing once derived tiles exist: the lock is held by the PARENT’s home, so a user who clicks a game tile can be refused because a DIFFERENT app (the Steam launcher, or another game from the same install) is running, and without the session id the refusal reads as a bug. See control-api.md §Derived tiles.
Steam library discovery Phase 3, ADDITIVE: present on the 409 conflict from DELETE /v1/apps/{id} when the app has derived tiles and ?delete_derived=true was not sent. A LIST, not a count - the point of the confirmation is that the admin sees what they are about to destroy. Capped; an empty array means the tiles could not be listed, never that there are none.
