 - In direct sessions with Will, cron jobs should use the `automation` agent by default unless Will explicitly says otherwise in that session.
 - Council tiers should use local LiteLLM-backed models for usage monitoring: light = `litellm/gpt-5.3-codex` with low thinking, medium = `litellm/gpt-5.3-codex` with high thinking, heavy = `litellm/gpt-5.4` with high thinking.
 - For non-trivial implementation work, treat `WIP.md` as the canonical state file and update it after each completed task/sub-task with status, concrete evidence, and the next recommended action.
+- If a subagent model choice causes execution/auth issues, prefer retrying implementation work on Codex GPT-5.4.
 
 ## Infrastructure notes worth remembering
 - Full `~/.openclaw` backups upload to MinIO bucket `zap` and are scheduled via OS cron every 6 hours.
