Module content_addressed_cache_v2 

Content-Addressed Cache V2 — multi-tier eviction with admission control.

Provides a production-grade, purely in-memory cache keyed by 32-byte CIDs with:

• Hot tier: LRU eviction, short TTL, fastest access
• Warm tier: LFU eviction, longer TTL, larger capacity
• Bloom-filter admission gate: three FNV-1a hash functions prevent one-hit wonders
• Eviction log: bounded ring of the last 500 eviction events
• TTL sweep: single-pass expiry across both tiers
• Warm drain: simulate write-back of least-frequently-used 25% to slower storage
