no predictions available (run predict first)

Error message

no predictions available (run predict first)

What it means

Bailed by the repair step when `example.predictions` is empty. Repair sends the first prediction's `actual_output` to the model as the teacher response to correct, so at least one prediction must exist. The guard fires when repair runs before the predict step, or when predict stored no predictions for the example.

Solutions

1. Run the predict step for the examples before repair
2. Check the example JSONL to confirm predictions were persisted (non-empty `predictions` array)
3. If predict is failing for these examples, fix the provider error it reports first

if example.predictions.is_empty() {
    // run predict for this example before repair
    anyhow::bail!("cannot run repair: no predictions, run predict first");
}

Catch per example, classify as 'missing prerequisite', and route the example back to the predict stage instead of failing the run.

When it happens

Trigger: Invoking `ep repair` on examples whose `predictions` array is empty: predict never ran, was skipped for that example (e.g. provider errors), or the run was resumed from a file written before predict.

Common situations: Stage reordering in scripts; predict step skipping failed requests and leaving the array empty; stale intermediate files.
