Run the Verification Stack for a concurrent, distributed or systems-software property, from source archaeology through calibrated models, red team, proof and maintained regression. Use for /vstack-mode or an end-to-end verification workflow.

Map a pinned system into control, data and boundary views and build evidence-backed historical anchors before verification.

Choose verification tools and assurance tiers per property using state, scale, ownership and consequences.

Derive observable contracts, calibrate both legal and illegal behavior, then freeze owner-approved specifications and configurations.

Construct state transitions or computation descriptors from pinned code without hiding interleavings or unchecked assumptions.

Calibrate buggy/fixed/ablated behaviors and validate model conformance using real traces, witnesses and explicit mismatch triage.

Audit calibrated verification through independent attacks on fidelity, property/gate strength and scope extrapolation.

Search within a trace-validated model scope, classify counterexamples and validate fixes in both the model and real code.

Prove pinned design-model properties in one shared TLAPS module tree after invariant discovery, calibration and trace alignment.

Package verified scope into a project-local five-step regression skill and keep it aligned with future code revisions.
