@@ -28,6 +28,7 @@ Docs: https://docs.openclaw.ai
 - Agents/tools: ignore volatile `exec` runtime metadata when comparing tool-loop outcomes, so enabled loop detection can stop repeated identical shell-command results instead of resetting on duration, PID, session, or cwd changes. Fixes #34574; supersedes #41502. Thanks @gucasbrg and @Zcg2021.
 - Agents/fallback: classify internal live-session model switch conflicts as unknown fallback failures instead of provider overloads, preventing local vLLM endpoints from receiving misleading overloaded cooldowns. Refs #63229. Thanks @clawdia-lobster.
 - Discord: let thread sessions inherit the parent channel's session-level `/model` override as a model-only fallback without enabling parent transcript inheritance. Fixes #72755. Thanks @solavrc.
+- Gateway/plugins: skip stale configured channels whose matching plugin is no longer discoverable, point cleanup at `openclaw doctor --fix`, and keep unrelated channel typos fatal so one missing channel plugin no longer crash-loops the Gateway. Fixes #53311. Thanks @futhgar.
 - Control UI: keep session-specific assistant identity loads authoritative after WebSocket connect, so non-main agent chat sessions do not show the main agent name in the header after bootstrap refreshes. Fixes #72776. Thanks @rockytian-top.
 - Agents/Qwen: preserve exact custom `modelstudio` provider configs with foreign `api` owners so explicit OpenAI-compatible Model Studio endpoints no longer get normalized into the bundled Qwen plugin path. Fixes #64483. Thanks @FiredMosquito831.
 - MCP/bundle-mcp: normalize CLI-native `type: "http"` MCP server entries to OpenClaw `transport: "streamable-http"` on save, repair existing configs with doctor, and keep embedded Pi from falling back to legacy SSE GET-first startup for those servers. Fixes #72757. Thanks @Studioscale.

@@ -61,6 +61,12 @@ If config is invalid, install normally fails closed and points you at
 `openclaw doctor --fix`. The only recovery exception is a narrow bundled-plugin
 reinstall path for plugins that opt into
 `openclaw.install.allowInvalidConfigRecovery`.
+When a channel config references a plugin that is no longer discoverable but the
+same stale plugin id remains in plugin config or install records, Gateway startup
+logs warnings and skips that channel instead of blocking every other channel.
+Run `openclaw doctor --fix` to remove the stale channel/plugin entries; unknown
+channel keys without stale-plugin evidence still fail validation so typos stay
+visible.
 
 Packaged OpenClaw installs do not eagerly install every bundled plugin's
