A Case-Derived Five-Stage Decision-Audit Proposal for Feature-Evaluation Decisions in Analytics Systems: One Card-Transaction Illustration

Abstract

Supplementary Code S1 contains selected non-sensitive analysis runners, contracts, manifests, gate definitions, figure source, and aggregate outputs. The EXP-67/68 runners, contracts, and aggregate outputs are included but were not replayed or re-executed during this package build. For EXP-68, stage1_q.csv records only the observed-Q threshold; the refit-Q 97.5th percentile was not computed, so the full Section 3.4 gate was not evaluated. Verification is limited to the EXP-63 and EXP-66 aggregate replay (five CSV comparisons) and four PNGs within the figure check's stated mechanical scope; this verified subset does not define the entire code selection. Full model reproduction is incomplete. The package excludes original transaction data, original public-dataset files, customer-level predictions, person identifiers, and identifier-bearing metadata. Aggregate outputs derived from public datasets remain subject to the applicable dataset terms of use. MIT applies only to original package code and documentation, not to third-party material or datasets. A bounded static inspection of 20 external-data adapters found zero copied code; this finding is limited to that static check and is not a general provenance audit.
