The question

Could latency be reduced without hiding stale data or making invalidation impossible to reason about?

I segmented endpoints by consistency needs, introduced bounded TTLs, and made cache behavior visible through structured metrics.

The mock system sustained the target load with a smaller database footprint and predictable stale-data windows.

A cache policy is a product consistency decision disguised as infrastructure.
