The Rust changes were additionally checked for balanced delimiters and consistency of the modified model initializers, but a real `cargo test` remains required before production deployment.

+## 0.8.7 Temporary-session state cleanup
+
+- `activated_at` is now the only source of truth for Temporary Quick Thermostat ownership.
+- Removed the legacy `generation=0` / `local_thermostat_power` activation fallback from the backend and Web UI.
+- Removed the Temporary-session `generation` compatibility field and its legacy-only test path.
+- Kept ordinary Quick Thermostat state only as an independent lower-priority owner restored after Temporary hand-back.
+
 ## 0.8.6 Control-logic audit remediation
 
 - Separates ordinary Quick Thermostat handback state from Temporary Quick Thermostat lifecycle and makes fresh-session activation depend on `activated_at`.
