    What this page is

    This is generated FPF reference text from the specification preface or supporting sections. It helps interpret FPF; it is not FPF Reference product documentation.

    Methodology

    Use it to understand how the specification wants to be read, then return to a route, pattern, or work packet for active work. Cite generated IDs only when the wording changes the task decision.

    Content

    What TA contributes. Confidence in provers, checkers, model‑checkers, data classifiers and pipelines. TA is about the machinery, not the claim or kind semantics.

    TA‑patterns (informative):

    • Prover kernels. Audit/qualification of the kernel version used for VA proofs.
    • Automated Model‑checkers. Qualification against seeded faults; document limits (precision, nondeterminism).
    • Classifiers used for MemberOf. If membership uses ML or rules engines, qualify the classifier separately; any drift monitoring belongs to LA freshness.

    TA‑obligations (normative):

    • TA‑1. Tools critical to VA/LA SHALL declare their qualification status and version; guards SHALL reference these declarations when they matter. TA‑2. Lower tool qualification MUST NOT be hidden by relaxing F or widening G. target‑contexts may offset it by demanding more evidence in R (for example, extra tests), per policy.
