 - Agents/OpenAI: default direct OpenAI Responses models to the SSE transport instead of WebSocket auto-selection, preventing pi runtime chat turns from hanging on servers where the WebSocket path stalls while the OpenAI HTTP stream works. Thanks @vincentkoc.
 - Docker: prune package-excluded plugin dist directories from runtime images unless the build explicitly opts that plugin in, so official external plugins such as Feishu stay install-on-demand instead of shipping partial metadata without compiled runtime output. Fixes #77424. Thanks @vincentkoc.
+- Model switching: include the exact additive allowlist repair command when `/model ... --runtime ...` targets a blocked model, and make Telegram's model picker say that it changes only the session model while leaving the runtime unchanged. Thanks @vincentkoc.
 - CLI/update: disable and skip plugins that fail package-update plugin sync, so a broken npm/ClawHub/git/marketplace plugin cannot turn a successful OpenClaw package update into a failed update result. Thanks @vincentkoc.
 - CLI/update: use an absolute POSIX npm script shell during package-manager updates, so restricted PATH environments can still run dependency lifecycle scripts while updating from `--tag main`. Fixes #77530. Thanks @PeterTremonti.
 - Diagnostics: grant the internal diagnostics event bus to official installed diagnostics exporter plugins, so npm-installed `@openclaw/diagnostics-prometheus` can emit metrics without broadening the capability to arbitrary global plugins. Fixes #76628. Thanks @RayWoo.
