Search-path of extra directories, each holding a distinct subset of the .safetensors shards (no duplication). Each shard lives on one drive; demand preads hit whichever drive holds it, so concurrent expert loads parallelise across drives and combined capacity is used — a 400 GB container fits across two 250 GB drives the mirror (#421) can't. st_init kept as a back-compat wrapper. Verified locally: clean build, no regression on the default path (token-exact tiny models unchanged), and the split path itself validated token-exact (shard on a separate dir, metadata in primary -> 32/32 vs oracle). Composable with the #421 mirror. CI 8/8. Thanks @mohamedmastouri2000-boop.
