The Symphony Accordare Vector (SAV) resolves declared component composition and compatibility. Its engine is a freezing-path, read-only C++26 process. SAV composes exact typed projections but never takes source truth from the owner vectors.

​
Operations

SAV supports a rich set of evaluation operations:
  • Accord reference resolution into immutable derived CURRENT snapshots
  • Three-axis evaluation, comparison, and explanation
  • Composition graphs and disposable projections
  • Named Version validation and diff
  • Extension Capsule checks
  • Installation Blueprint planning
  • Compatibility negotiation between declared components

​
What SAV does not do

  • SAV does not take semantic ownership of the components it composes.
  • SAV does not choose a design for you; it evaluates what you declared.
  • SAV does not mutate canonical files. Its output is evidence and proposals.
  • SAV is not the STAV append authority. See the Accordare STAV producer for pre-mutation intent handling.
SAV is read, query, validate, and propose only. Programmatic canonical apply remains disabled across the SKV engine family.
