Formal Verification — Worked Example

Direct answer

Formal Verification — Worked Example is limited to the bound authority, implementation, or commercial acquisition state and carries its exclusions explicitly.

Answer contract

Apply the worked example lens only to the exact inspected source scope; do not infer authority from adjacent topics.

Evidence and exact locators

t21-formal-proof-lifecycle — lib/evidence-dossier/formal-proof-fixture.ts — FORMAL_PROOF_FIXTURE_DOSSIER and FORMAL_PROOF_FIXTURE_DIGEST. Supports: Binds a synthetic interval claim to a machine-checked Lean proof, deterministic calculation, sources, and an offline-verifiable package.

src-nist-formal-verification — Definition and Notes. Supports: Defines formal verification through formal requirements, a model, logic, and rules of inference.

What the evidence does not establish

A proof establishes deduction under declared assumptions, not empirical truth, source fidelity, kernel equivalence, or independent reproduction.

Does not establish that a particular model matches the implemented system or that a particular proof is sound.

Authority or implementation

This authority or implementation section is constrained to the same inspected scope: Binds a synthetic interval claim to a machine-checked Lean proof, deterministic calculation, sources, and an offline-verifiable package. Defines formal verification through formal requirements, a model, logic, and rules of inference.

It must preserve the recorded boundary: A proof establishes deduction under declared assumptions, not empirical truth, source fidelity, kernel equivalence, or independent reproduction. Does not establish that a particular model matches the implemented system or that a particular proof is sound.

Mechanism or acquisition state

This mechanism or acquisition state section is constrained to the same inspected scope: Binds a synthetic interval claim to a machine-checked Lean proof, deterministic calculation, sources, and an offline-verifiable package. Defines formal verification through formal requirements, a model, logic, and rules of inference.

It must preserve the recorded boundary: A proof establishes deduction under declared assumptions, not empirical truth, source fidelity, kernel equivalence, or independent reproduction. Does not establish that a particular model matches the implemented system or that a particular proof is sound.

Verification and uncertainty

This verification and uncertainty section is constrained to the same inspected scope: Binds a synthetic interval claim to a machine-checked Lean proof, deterministic calculation, sources, and an offline-verifiable package. Defines formal verification through formal requirements, a model, logic, and rules of inference.

It must preserve the recorded boundary: A proof establishes deduction under declared assumptions, not empirical truth, source fidelity, kernel equivalence, or independent reproduction. Does not establish that a particular model matches the implemented system or that a particular proof is sound.

What this does not establish

This what this does not establish section is constrained to the same inspected scope: Binds a synthetic interval claim to a machine-checked Lean proof, deterministic calculation, sources, and an offline-verifiable package. Defines formal verification through formal requirements, a model, logic, and rules of inference.

It must preserve the recorded boundary: A proof establishes deduction under declared assumptions, not empirical truth, source fidelity, kernel equivalence, or independent reproduction. Does not establish that a particular model matches the implemented system or that a particular proof is sound.
