Zero-Heap Compliance
Demonstrating QualiaDB's strict zero-allocation architecture for predictable performance via WASM.
Zero-Heap Operations Demo
Run operations and watch the heap allocation counter stay at zero. All operations use stack-allocated buffers and caller-supplied output arrays.

The 48-Byte Super-Quin
Every semantic statement in QualiaDB is exactly 48 bytes. No pointers, no heap references, just bit-packed semantics.
Bit-Packed Semantics
Subject
FNV-1a hash of entity IRI (63 bits) + MSB flag
Predicate
Property hash (bits 8-62) + opcode (bits 0-7) + modality MSB
Object
IRI hash, integer, decimal, or did:q42 pointer (type tag in bits 60-62)
Context
Sensitivity class (bits 56-63) + contract/world hash (bits 0-55)

Memory Usage Comparison
Scale comparison for a WordNet-sized graph (5.56M triples). The live demo above runs the real WASM query kernel on a 1,000-Quin buffer; these bars are published-scale estimates, not this page’s heap counter.
Traditional RDF Store
~2.8 GB (Jena/Fuseki)
Heavy heap allocation, GC pauses
Graph Database
~1.5 GB (Neo4j)
Pointer-based, unpredictable memory
QualiaDB
~280 MB (Full Load)
Zero-heap, deterministic memory

Real-Time Memory Monitor
Monitor memory usage in real-time as operations execute. The 42MB Sentinel enforces a hard ceiling.
