# Source modifications and dates

Original archives and copyright/license texts are retained unchanged. Their exact snapshots are recorded in distribution-manifest.json.
The following upstream adaptation histories identify C/glue/build changes and dates; the accompanying diff compares the C overlay to FFmpeg n5.1.4, not to a claimed pristine historical binary.

## Packaging changes, 2026-10-04
Melukis source-package preparation splits the two oversized archives without changing the reassembled bytes, supplies explicit notices and manifests, and adds download/verification instructions.
Dockerfile.locked is a disclosed optional reconstruction adaptation: local source copies replace Git fetches, the current SDK image is pinned and an unneeded experimental frontend directive is removed. Original configure/link/export flags and controlling scripts are retained.
No new WASM compilation was performed and no private Melukis app source or license was changed. See Dockerfile.locked.CHANGES.txt.
