Primes¶
- Mixed Layer
- The sharp lower discontinuity is the steep jump in access cost from cache (microseconds) to cold storage (milliseconds or more) — and that sharpness is what lets the cold tier remain a large, slow, undifferentiated-by-recency archive while the cache buffers it from raw query patterns.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
