cache_load measured pipeline-cache.bin with ftell into a long, which is 32 bits on Windows: a file past 2 GB measured as -1, so the run started with an empty cache and the log said nothing, not even that the file was over pipeline_cache_max_mb. The read now lives in runtime/vk_cache_file.h: the length comes from the 64-bit tell, the read runs in 64 MB pieces, and a refusal returns its reason and the file's size, which cache_load logs. The Windows atomic write no longer cuts a block of 4 GB or more to a 32-bit count. tests/pipeline_cache_file_check.py reads a sparse file just over 2 GB through the header. With --probe-prewarm and such a file carrying this GPU's header, the log reads "holds 2048 MB, over NX2NAVI_PIPELINE_CACHE_MAX_MB 512" under the default limit and "2048.0 MB read" with the limit off; the exe before this change logged nothing for the same file.
