Set up the Codex Operating Policy

Create the policy at <codex-home>/instructions/codex-operating-policy.md and set model_instructions_file in the user-level config.toml to that path. Update the policy file when it already exists. Codex reads it as its model instructions. Offer model_verbosity = "low" as an additional config change, subject to the user's separate explicit approval.

1. Inspect the target and ask about language

Resolve CODEX_HOME, falling back to the user's .codex directory. Inspect the policy destination and config.toml, especially an existing model_instructions_file, model_verbosity, and developer_instructions. Read referenced policy files as needed to identify actual instruction conflicts. Limit inspection to relevant instruction sources.
