strata metal stream: 2.60 GB allocated before the arena (the process holds 2.24 GB, 5.40 GB resident); RAM 25.8 GB (12.2 GB available, 7.0 GB kept for macOS), GPU working set 19.1 GB
strata metal stream: planned resident footprint 9.6 GB decode (10.7 GB virtual peak during prefill with 1.12 GB transient prompt scratch) = arena 6.5 + 2.6 held before it + 0.5 reserved for the n-gram table; cap 18.8 GB = the lesser of the GPU working set 19.1 GB and the RAM 25.8 GB less 7.0 GB left to macOS and its file cache
