Provider coverage
SCV covers the following providers and resource types:- AWS
- Azure
- Google Cloud Platform
- DigitalOcean
- Cloudflare
- User-owned hardware (where comparison with offsite resources is required)
Installed engines
SCV knowledge is delivered through eight independently installable C++ engines. You install only the ones you need:scv-engine
Core SCV engine for provider resource knowledge and graph construction.
scev-engine
Cloud evidence engine for bounded capture and corpus semantics.
scev-cf-engine
Cloudflare-specific evidence engine.
schv-aws-engine
AWS-specific hardware and resource knowledge engine.
schv-azure-engine
Azure-specific hardware and resource knowledge engine.
schv-do-engine
DigitalOcean-specific resource knowledge engine.
schv-gcp-engine
GCP-specific hardware and resource knowledge engine.
scv-graph-duckdb-connector
Optional relational graph connector using DuckDB for retained SQL indexing.
Portable provider packages and composition
SCV exposes portable provider packages through qxctl. You retain control over requirements, provider permissions, recipe alternatives, and execution decisions. qxctl supports retained workflows and protected graph selection, so you can replay exact evidence without re-querying providers.Optional DuckDB connector
Thescv-graph-duckdb-connector adds a bounded relational projection of immutable native graphs. DuckDB is the user-selected default SQL database. You may select dedicated graph engines in the future through additional adapters.
Privacy and sovereignty
An installed SCV knowledge graph belongs to your private installation. User-supplied accounts, balances, permissions, and contractual constraints are used only through explicitly enabled observation surfaces. Private facts do not enter official Symphony source truth.How SCV relates to other vectors
SOV
The operational control plane that acts upon SCV evidence. SOV does not rewrite provider meaning.
SNV
Records the identities of physical Nodes and clusters that result from SCV-informed provisioning.
SHV
Owns detailed hardware capability knowledge for components SCV references.
