Read-only packs of encoded cache entries are mapped once at startup from the shader cache prebuilt directory (plus ANYPS5_PREBUILT_SHADER_CACHE, opt out with ANYPS5_NO_PREBUILT_SHADERS). Disk loads try packs and loose prebuilt folders first and fall through to the writable cache and the compiler on a miss. Keys, source version, format and payload checksums are validated exactly as for writable entries, and interval logs report prebuilt hits, misses, rejections and load timings. Depends on the uncached compile entry point only through the offline tool that produces these packs; the loader itself is independent.
