Fleet worker {} has an inconsistent persisted prompt

Error message

Fleet worker {} has an inconsistent persisted prompt

What it means

The registered launch manifest's prompt must equal the registered objective, and the registered objective must equal the freshly expected objective optionally extended with the bounded 'Accepted coordination decisions' projection header. A mismatch means the persisted prompt no longer describes the task this lease is for, and relaunching from it could run the wrong instructions.

Solutions

1. Do not edit task specs mid-run; cancel and create a new run with the edited objective
2. Complete or cancel the drifted worker so a fresh, consistent launch record is created on retry
3. Verify all fleet processes use the same Codewhale version so prompt derivation is stable

match validate_registered_launch_spec(&record.spec, &expected) {
    Ok(()) => Ok(()),
    Err(err) if err.to_string().contains("inconsistent persisted prompt") => {
        // objective drifted: cancel task and re-lease instead of relaunching stale instructions
        Err(err)
    }
    Err(err) => Err(err),
}

When it happens

Trigger: The task's objective was edited or re-derived differently from when the worker registered (spec change, migration, partial event replay), so manifest.prompt diverges from objective/expected prompt.

Common situations: Editing task specs between retries; resuming a run after a Codewhale upgrade that changed prompt derivation; ledger rebuilt from a subset of events.
