@@ -11,6 +11,7 @@ Docs: https://docs.openclaw.ai
 - Telegram: detect polling stalls from `getUpdates` liveness only, so outbound API calls no longer mask dead inbound polling; log polling-cycle starts after transport rebuilds. Fixes #78473.
 - fix(plugins): scan installed dependency runtime code [AI]. (#81066) Thanks @pgondhi987.
 - Inherit tool restrictions for delegated sessions [AI]. (#80979) Thanks @pgondhi987.
+- Codex harness: make the live test wrapper portable to Windows and defer locked temp cleanup so native Windows and WSL2 live runs complete.
 - Telegram: discard legacy long-poll update offsets that cannot be tied to the current bot token, so token rotation no longer leaves bots silently skipping new messages. (#80671) Thanks @sxxtony.
 - browser: enforce navigation checks for act interactions [AI]. (#81070) Thanks @pgondhi987.
 - Validate node exec event provenance [AI]. (#81071) Thanks @pgondhi987.
