Byte-exact format
The format fixes its image, inspection, profile, and codebook tags; a 1304-pixel width; the Sunlit Amber palette; page geometry; fixed-Huffman PNG encoding; stored-ZIP grammar; page order; and manifest bytes.
The decoder accepts up to 1 MiB of source, 16,384 reader nodes, reader depth 256, and 32 pages. It validates lengths and offsets before allocation. Reed–Solomon parity detects changed payload symbols, and regeneration checks the exact supplied PNG or ZIP bytes.

| Product | Role |
|---|---|
| Lispex Image | Carries exact source bytes in a canonical PNG or page set |
image inspect | Reports format, profile, page count, source identity, and commitments |
image decode | Returns source after structure, integrity, parity, and regeneration checks |
| Vouch | Connects recovered source identity to authentication, request binding, re-execution, and a local gate |
| Host media workflow | Owns visual presentation, resizing, distribution privacy, and access control |
