Show HN: A memory database that forgets, consolidates, and detects contradiction

Show HN: A memory database that forgets, consolidates, and detects contradiction Vector databases store memories. They don&#x27;t manage them. After 10k memories, recall quality degrades because there&#x27;s no consolidation, no forgetting, no conflict resolution. Your AI agent just gets noisier.<p>YantrikDB is a cognitive memory engine — embed it, run it as a server, or connect via MCP. It thinks about what it stores: consolidation collapses duplicate memories, contradiction detection flags incompatible facts, temporal decay with configurable half-life lets unimportant memories fade like human memory does.<p>Single Rust binary. HTTP + binary wire protocol. 2-voter + 1-witness HA cluster via Docker Compose or Kubernetes. Chaos-tested failover, runtime deadlock detection (parking_lot), per-tenant quotas, Prometheus metrics. Ran a 42-task hardening sprint last week — 1178 core tests, cargo-fuzz targets, CRDT property tests, 5 ops runbooks.<p>Live on a 3-node Proxmox homelab cluster with multiple tenants. Alpha — primary user is me, looking for the second one.
