 - Channels/Telegram: publish webhook runtime state and warn when `setWebhook` has not completed after startup grace, so webhook-mode accounts no longer look healthy while registration is still failing or retrying. Refs #74299. Thanks @lolaopenclaw and @martingarramon.
 - Channels/Telegram: bound native command menu `deleteMyCommands` and `setMyCommands` Bot API calls and allow the same timeout-triggered transport fallback retry as other startup control calls, so Windows/WSL network stalls cannot leave command sync hanging behind an otherwise running provider. Refs #74086. Thanks @SymbolStar.
 - ACP/commands: accept forwarded ACP timeout config controls in the OpenClaw bridge, treat unsupported discard-close controls as recoverable cleanup, and restore native `/verbose full` plus no-arg status behavior, so Discord command menus and nested ACP turns no longer fail on supported session controls. Thanks @vincentkoc.
+- Codex harness: interrupt and release native app-server turns that go quiet after an OpenClaw dynamic-tool response without sending `turn/completed`, so Discord and other chat lanes do not stay stuck in `processing`. Thanks @vincentkoc.
 - Codex harness: bound OpenClaw dynamic tool responses to 30 seconds and fail closed with an explicit tool result when the app-server bridge would otherwise strand the turn in `processing`. Thanks @vincentkoc.
 - TUI/status: clear stale `streaming` footer state when a final event arrives after the active run was already cleared and no tracked runs remain, while preserving concurrent-run ownership and inactive local `/btw` terminal handling. Fixes #64825; carries forward #64842, #64843, #64847, and #64862. Thanks @briandevans and @Yanhu007.
 - Channels/Discord: fail startup closed when Discord cannot resolve the bot's own identity and keep mention gating active when only configured mention patterns can detect mentions, so the provider no longer continues with a missing bot id. Fixes #42219; carries forward #46856 and #49218. Thanks @education-01 and @BenediktSchackenberg.

@@ -575,6 +575,13 @@ an OpenClaw response within 30 seconds. On timeout, OpenClaw aborts the tool
 signal where supported and returns a failed dynamic-tool response to Codex so
 the turn can continue instead of leaving the session in `processing`.
 
+After OpenClaw responds to a Codex turn-scoped app-server request, the harness
+also expects Codex to finish the native turn with `turn/completed`. If the
+app-server goes quiet for 60 seconds after that response, OpenClaw best-effort
+interrupts the Codex turn, records a diagnostic timeout, and releases the
+OpenClaw session lane so follow-up chat messages are not queued behind a stale
+native turn.

 Environment overrides remain available for local testing:
