Low-Context Execution Packet

Use branch stage/d3-05-asset-extraction-gallery.

Use only the sources and commands approved in docs/D2_ASSET_SOURCE_MANIFEST.md. Keep first-pass extraction narrow: title screen logo, title fonts, snow/background textures, and one ambient audio candidate.

External staging layout:

/mnt/kitchen/collab/d3-tui/asset-staging/raw/d2-title/
/mnt/kitchen/collab/d3-tui/asset-staging/converted/d2-title/
/mnt/kitchen/collab/d3-tui/logs/d3-05/

Commit only:

• provenance manifest
• small scripts
• gallery HTML/Markdown
• selected preview files through Git LFS if they are useful and safe

Provenance row format:

asset_id,source_disc,source_path,extraction_command,raw_path,converted_path,format,sha256,notes

Conversion priorities:

• textures: PVR/KMG/raw to PNG preview
• geometry: native candidate to OBJ or glTF preview
• audio: source candidate to WAV or OGG preview

Search the intel DB before committing texture conversion assumptions:

scripts/intel/query-shachi-atoms.sh search "PVR texture"
scripts/intel/query-shachi-atoms.sh search "twiddle texture"

Gallery minimum:

• one index page at gallery/index.html or docs/D2_ASSET_REVIEW_GALLERY.md
• thumbnail or link for each preview
• source/provenance next to each item
• clear “approved / uncertain / reject” status field

Verification:

git lfs status
git check-attr filter -- assets/converted/example.png

If no exact D2 asset can be extracted cleanly, produce a report with logs and a fallback plan using original recreation assets. Do not invent provenance.
