Room topology (retired)

The room topology feature was removed at the operator's request because the Displays & AV configuration was unreliable. Use the TV Routing Matrix, its TV/source drawers, the Settings display editor and the original receiver Setup.

The previous editor, target-picker overrides, ordering observer and server-side projection wrappers are removed. The normal receiver/group and Pluto label stores are authoritative again. Already-saved values and all stable identities remain. The historical room.topology preference is retained untouched for recovery; it must not override current configuration. Old topology-only saves return HTTP 409 and require reloading the controller.

See TV Routing Matrix for controls, data preservation, upgrade, rollback and verification. This page remains at its old path so existing links do not suggest that the retired editor is still an operator workflow.
