Detailed Description

One ::ra8_vmem instance sized for a swept block size + its storage.

Frame storage, metadata, and buckets are carved from explicit caller bindings per leg so every leg starts cold; cbs_meter_t counts storage commands (== misses) and delivered bytes.

Invariant

frames == k_cbs_cache_bytes / frame_bytes (>= 1).
