To choose the right Rust verification tool for ZirOS, apply the ZirOS decision tree and evidence rules to classify targets as counted, bounded, or comparison-only. This produces explicit lane recommendations with referenced evidence paths from the tool-matrix.

Counted, bounded, and comparison-only verification claims are classifications determined by the ZirOS decision tree and evidence rules. They define the verification boundary and guide the selection of the appropriate lane for a specific Rust surface.

Yes, ZirOS doctrine supports verification with RefinedRust, Verus, Kani, Thrust, Flux, Creusot, and Prusti. The decision tree guides tool selection across these options to shape verification boundaries.

To apply decision-tree rules and produce lane recommendations, read references/tool-matrix.md and references/decision-tree-and-evidence.md to determine the recommended verification lane for a given ZirOS Rust surface.

When to use Prusti, Creusot, or Verus depends on the ZirOS decision tree classification of your target as counted, bounded, or comparison-only. The tool-matrix references provide the evidence paths to distinguish the best lane.

The ZirOS tool-matrix limits Rust verification to the supported tools: RefinedRust, Verus, Kani, Thrust, Flux, Creusot, and Prusti. It requires targets to be classified by the decision tree before producing lane recommendations.
