job {job_id} has no {field}

Error message

job {job_id} has no {field}

What it means

manifest_path() requires every completed job to have a non-empty source_path and output_path string in imagegen-jobs.json. The {field} in the message is whichever of source_path or output_path is missing. Without both, finalize cannot locate the files to hash-check provenance.

Solutions

1. Re-ingest the job with record_imagegen_result.py, which populates source_path and output_path.
2. If editing manually, ensure both source_path and output_path are non-empty strings (absolute, or relative to run_dir).
3. Re-run finalize_pet_run.py.

Example fix

// before
{ "id": "idle", "status": "complete", "source_path": "" }
// after
{ "id": "idle", "status": "complete", "source_path": "<generated_images>/ig_xxx.png", "output_path": "decoded/idle.png" }

import json
from pathlib import Path

manifest = json.loads(Path("<run_dir>/imagegen-jobs.json").read_text())
for job in manifest["jobs"]:
    if job.get("status") == "complete":
        for field in ("source_path", "output_path"):
            assert isinstance(job.get(field), str) and job[field], f"job {job.get('id')} has no {field}"

def job_has_paths(job: dict) -> bool:
    return all(isinstance(job.get(f), str) and job[f] for f in ("source_path", "output_path"))

When it happens

Trigger: A job whose status is "complete" but whose source_path or output_path is absent, empty, or not a string in the manifest.

Common situations: Hand-editing imagegen-jobs.json instead of using record_imagegen_result.py; a partially-written manifest from a killed ingest; an older manifest format missing output_path.
