Loose files in the install now answer the opens 1.12.1 flags, ahead of the archives (`0x647e60`, benilla-re `storm/mount`).
- The index walks the install folder, then `Data\`, keyed case-insensitively; the first entry wins.
- It answers interface files and textures, fonts (bare name first), cursors, sound, model frames and the minimap arrows.
- A `.MPQ` file answers its name from inside it.
- A name written with `/` misses, as in 1.12.1.
- A found file that fails to read does not fall back.
- The index empties where the reference empties it (`0x646fc0`): after saved variables, `AddOns.txt` and the glue sweep.
- A `Blizzard*` addon folder holding its `.toc` is skipped unread (`0x51fb50`), so the archive's copy loads. Nothing in the install is moved.
Each change has a test that fails without it.
