Metrics combines both structural write-read separation (frozen tags for write identity, subset matching for read flexibility) and per-use-case cost optimization (eager sorted insertion on writes, deferred matching on reads) within a single module — suggesting that structural and economic separation can be two facets of the same design.
Metrics achieves both structural AND economic write-read separation in a single module
