Missing VideoEnhanced.hyp in hyp-files and pipeline gap detection

[madjin]

Summary

videoenhanced is present in manifests/catalog metadata, but its source .hyp file is missing from hyp-files/, resulting in a non-downloadable entry.

Current Evidence

• context/hyp_index.raw.json has an entry for VideoEnhanced.hyp with:
  • status: "pending"
  • local_path: null
• context/apps/videoenhanced/manifest.json points to source.hyp_filename: "VideoEnhanced.hyp"
• hyp-files/VideoEnhanced.hyp does not exist
• catalog/catalog.json currently shows for videoenhanced:
  • hyp_filename: "VideoEnhanced.hyp"
  • download_path: null
  • has_download: false

Why This Matters

• Catalog can include entries that appear complete but have no downloadable .hyp artifact.
• This should be detected and surfaced earlier in ingestion/build pipeline.

Repro

1. Run:
   • python3 scripts/catalog/build_explorer_data.py
2. Observe failure:
   • Missing .hyp reported for videoenhanced
   • Non-zero exit code in strict mode

Desired Behavior

• Pipeline should fail as soon as a manifest references a missing hyp-files/*.hyp (default strict mode).
• Build output should include a machine-readable report of missing files.
• CI should block merges/releases when missing .hyp artifacts exist.

Suggested Follow-ups

1. Fix ingestion/download stage so VideoEnhanced.hyp is retrieved (or remove the app entry intentionally).
2. Add CI gate to run strict build and fail on missing .hyp.
3. Keep/report missing artifacts in a stable location (tmp/manifests/missing-hyp-files.json) for debugging.

Acceptance Criteria

• hyp-files/VideoEnhanced.hyp exists OR videoenhanced is intentionally removed from published catalog.
• Strict build passes without missing .hyp errors.
• CI fails if future missing .hyp regressions occur.
