The SCV source-knowledge engines are eight independently packaged C++26 processes that hold private semantic knowledge about offsite provider resources, offerings, regions, constraints, and hybrid possibilities. They preserve exact source revisions and bounded captures so downstream tools can reproduce results.

​
Engines

scv-engine

Umbrella SCV source engine for the shared cloud vocabulary.

scev-engine

Symphony Cloud Edge Vector source engine.

scev-cf-engine

Cloudflare-specific edge source engine.

schv-aws-engine

Amazon Web Services source engine.

schv-azure-engine

Microsoft Azure source engine.

schv-do-engine

DigitalOcean source engine.

schv-gcp-engine

Google Cloud Platform source engine.

scv-graph-duckdb-connector

Optional DuckDB connector for retained relational graph indexing.

​
What the SCV engines do

  • Preserve explicit source revisions and bounded captures
  • Retain qualified claims and native document structure
  • Produce reproducible graph and query evidence
  • Feed portable provider packages and finite caller-directed composition

​
What they do not do

Provider operations and complete cloud catalogs remain outside this increment. The SCV engines describe what is known; they do not act on providers.
qxctl separately administers audited local source changes and coherent graph selection through retained workflows and protected graph selection. Dedicated graph traversal and operational adapters remain separate work.

SCV vector
