FPA supplementary derivations for FPA-FRESHNESS-PORTABILITY-003

Abstract

This supplement records five additional target paradigms for the Freshness Portability Agent (FPA-FRESHNESS-PORTABILITY-003): Common Lisp, Brainfuck, spreadsheet formulas, an Analytical Engine-style program, and AWK. It is separate from the canonical FPA package and its Non-Normative Tests (NNT) companion. The supplement Manifest names and hashes the canonical FPA package Manifest as its parent artifact. The FPA Specification, Conformance Tests, Semantic Index, Coverage Matrix, and Ambiguity Register define the rules and acceptance criteria. Integrity.

The FPA package is archived as a separate record: https://doi.org/10.5281/zenodo.23390618. Use of AI tools. The author designed and calibrated the harnesses of the derivations in this supplement. Large language models were used openly, as tools to accelerate research and production, with manual review: they produced the renderings (Common Lisp, Brainfuck, spreadsheet formulas, an Analytical Engine-style program and AWK) and the comparators (the Rust rendering and the reference output spec_252.txt) in an AI-provider environment, as the study artifacts reported in Section 6 of the article; they are not reference implementations. No tool is an author; the author is accountable for the content. What matters is not which tools touched the files but whether they can be verified: the supplement has its own Manifest, which names the pack Manifest as its parent.
