@@ -60,6 +60,7 @@ Docs: https://docs.openclaw.ai
 - Gateway: avoid repeated plugin tool descriptor config hashing so large runtime configs do not block reply startup and trigger reconnect/timeouts. (#75944) Thanks @joshavant.
 - Plugins/externalization: keep diagnostics ClawHub packages and persisted bundled-plugin relocation on npm-first install metadata for launch, and omit Discord from the core package now that its external package is published. Thanks @vincentkoc.
 - Setup/TUI: bound the Terminal hatch bootstrap run so a stalled provider request times out instead of leaving first-run hatching stuck behind the watchdog. (#76241) Thanks @joshavant.
+- Cron/CLI runtimes: route isolated cron jobs through configured CLI runtimes only when the resolved model provider is compatible, so OpenAI job overrides no longer inherit a mismatched Claude CLI backend. Thanks @vishutdhar.
 - Plugins/Codex: allow the official npm Codex plugin to install without the unsafe-install override, keep `/codex` command ownership, and cover the real npm Docker live path through managed `.openclaw/npm` dependencies plus uninstall failure proof.
 - Gateway/status: add concrete service, config, listener-owner, and log collection next steps when gateway probes fail and Bonjour finds no local gateway, so frozen or port-conflict reports include the data needed for root-cause triage. Refs #49012. Thanks @vincentkoc.
 - Codex harness: forward OpenClaw workspace bootstrap files such as `SOUL.md` through native Codex config instructions while leaving `AGENTS.md` to Codex project-doc discovery. Fixes #76273. Thanks @zknicker.
