job {job_id} source image no longer exists: {source}

Error message

job {job_id} source image no longer exists: {source}

What it means

The job's source_path was recorded, but the source image file (the original ig_*.png under CODEX_HOME/generated_images) no longer exists on disk. finalize cannot re-hash it, so provenance cannot be confirmed.

Solutions

1. Check ls <source_path> and verify CODEX_HOME still points where the image was generated.
2. If the source was removed, regenerate it via $imagegen and re-ingest with record_imagegen_result.py to update the path and hash.
3. Keep generated_images intact until finalize completes.

import json, os
from pathlib import Path

run_dir = Path("<run_dir>")
manifest = json.loads((run_dir / "imagegen-jobs.json").read_text())
for job in manifest["jobs"]:
    src = job.get("source_path")
    if isinstance(src, str) and not Path(src).is_absolute():
        src = run_dir / src
    if job.get("status") == "complete":
        assert Path(src).is_file(), f"source missing for {job.get('id')}: {src}"

When it happens

Trigger: The recorded source file was deleted, moved, or CODEX_HOME changed so the absolute path now resolves to nothing.

Common situations: Garbage-collection of old generated images before finalize runs; switching machines or HOME; a temp/cleanup process removing generated_images entries.
