CUE framework for modeling any domain where things depend on other things.
You declare resources with a type (@type) and dependencies (depends_on). The framework computes everything else: deployment plans, impact analysis, blast radius, rollback sequences, JSON-LD graphs, SHACL shapes, DCAT catalogs, PROV-O audit trails. All as deterministic projections of one validated source of truth. No runtime, no database, no external serializer. Everything is cue export.
Layer 0 ─ apercue.ca Generic graph patterns + W3C projections
#Graph, #Charter, #ComplianceCheck
JSON-LD, SHACL, SKOS, EARL, OWL-Time
│
Layer 1 ─ quicue.ca Infrastructure-specific patterns
40+ types, 33 providers, execution plans
│
Layer 2 ─ instances Domain-specific graphs
├─ cmhc-retrofit Construction PM (NHCF, Greener Homes)
├─ homelab Homelab infrastructure
└─ maison-613 Real estate operations (private)
│
Layer 3 ─ services Pre-computed outputs
├─ api.quicue.ca 654 static JSON endpoints
├─ demo.quicue.ca D3 operator dashboard
└─ kg.quicue.ca Knowledge graph framework
demo.quicue.ca --- D3 dependency graph, execution planner, resource browser, Hydra explorer. 30 resources, 654 resolved commands, all from one CUE evaluation.
apercue.ca --- Landing page + ecosystem explorer. The generic foundation layer proving compile-time W3C linked data works.
api.quicue.ca/docs --- Swagger UI. 654 endpoints across 33 providers.
All data uses RFC 5737 TEST-NET IPs and RFC 2606 example.com hostnames. Safe to explore.

CUE comprehensions precompute all queries at eval time. CUE unification enforces all shapes. Every W3C artifact is a zero-cost projection.
