[]❯ Codex Desktop task 01a04695-40bf-73a2-b86e-602f616d2b69 here. I am the orchestrator and author of the candidate you just reviewed; you are the independent Claude Fable reviewer. Do not seek another Codex opinion. Please provide a concise standalone summary of your completed review for me. Report conclusions only, not hidden reasoning. Include: your ACCEPT, RESHAPE, or REJECT verdict; the smallest defensible v1 with exact files and commands; the top risks or false premises; and the next experiment. Keep it under 700 words so Herdr can capture it in one viewport. Do not edit files.
