GlyphCAS
Exact content, typed semantic identity, and evidence-preserving reuse for language-model systems
Conventional content-addressable storage is exact by design: identical bytes receive identical content identities; different bytes do not. Language-model systems often want a second property: repeated meanings, structures, plans, or outputs should be reusable even when their surface bytes differ. A naive “semantic hash” can create speed, but it can also erase provenance, collapse task-specific differences, cross project or authority boundaries, and promote approximate similarity into false exactness.
GlyphCAS is a layered identity and reuse architecture that keeps exact content identity sovereign while adding typed, contract-bound derived identities. It separates content, semantic, contextual, dependency, representation, logical, and receipt identities. A model may propose a semantic graph or reuse candidate, but deterministic canonicalization, schema validation, authority checks, versioned compilers, and explicit Equivalence Contracts decide whether an alias may be minted or used.
The reference package implements exact SHA-256 storage, deterministic canonical JSON over a bounded subset, Unicode normalization, content-addressed semantic identities, contextual reuse keys, controlled paraphrase snapping, project and authority isolation, dependency invalidation, hash-chained receipts, fold/2 representation objects, exact recipe verification, prefix/KV cache keys, deterministic software routing, and ten passing unit tests.
The current evidence supports a reference architecture and narrow mechanism claims. It does not establish universal semantic canonicalization, universal model-independent cache reuse, production latency gains, or a general-purpose compression result.
