Constant CLAUDE_CODE_REFUSAL 

pub const CLAUDE_CODE_REFUSAL: &str = "claude-code scheduled jobs are session-scoped runtime state: they are created by the model \
     inside a session (`CronCreate`) and restored on resume. Claude Code publishes no harness verb \
     a client can call, so supercode refuses rather than inventing one";

Why Claude Code refuses every mutating job verb.
