Jigsaw Pieces — shipped photo index

What this is

Each line of jigsaw_photo_index.txt (a01 1, a03 1, …) names a sibling file in assets/ that is a standalone UnityFS AssetBundle holding exactly one Texture2D. All 197 decoded without error — uniform 610×890, ASTC 6×6, ~232 KiB per bundle, 44.6 MiB total. Index and payloads match exactly: no missing files, no unindexed bundles. The second column is a flag, and it is 1 for every entry.

These are a baseline, not the full catalog. Numbering inside each letter is sparse — a reaches 108, s reaches 110, v reaches 119, yet only 197 files ship. Against the highest index per letter that is roughly 17% coverage. The IL2CPP metadata agrees: JigsawPhotos.cs carries no shipped index at {0} and every photo will be fetched as though nothing were cached, so the rest arrive at runtime.

Letter prefixes do not map to a visible theme — b01 is a raccoon, k02 a robot, v03 a capybara, o03 a strawberry. They read as batch or artist codes. Levels themselves are config-driven via LevelDefinition, which references pictures by name.
