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
Qualify provers, checkers, measurement pipelines, and classifiers separately. A classifier output can support an assertion about J; the tool neither becomes the candidate nor makes the governed criterion hold. Version drift may make the support unavailable and hence produce unknown for a candidate-bearing use.
- TA-1. Every tool whose qualification is relied on by VA or LA SHALL identify its exact version and qualification status, and the receiving guard SHALL recover that declaration when the reliance is current.
- TA-2. Missing or weaker tool qualification MUST NOT be hidden by lowering the owning episteme's F or widening G. The receiving policy may require additional independent support, reduce or condition R, or refuse the use while preserving the exact unavailable-support reason.
