The overlay only wrapped the five loaders the boot path needed, leaving a silent-failure hole: any future state (or current code like Sound.lua's widenMono, which re-reads the pika-cry WAV via love.sound.newSoundData with the caller's bare path) could load a generated asset through an unwrapped API and silently degrade on hardware. NxAssetOverlay now wraps every read-side love function that accepts a filesystem path (filesystem.read/load/lines/newFileData/getInfo, graphics.newImage/newFont, image.newImageData, audio.newSource, sound.newSoundData, font.newFontData), so new states and mods fall inside the Blue/Yellow fallback with zero per-call-site work. Write-side functions stay stock, proven by identity assertions in the fallback suite. The static guard's forbidden-literal list covers the same APIs. Co-authored-by: Cursor <cursoragent@cursor.com>
