Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The change restricts three interactive prompts to 1 or 2, preventing invalid numeric values from reaching integer coercion. The implementation risk is low, but valid-input behavior and source-package test coverage remain incompletely demonstrated. Possibly related PRs

🔍 Regression tests bypass package checks
This exclusion removes the new tests from the source package used by R CMD check. CI therefore provides no built-package regression coverage.

🔍 Valid-input test permits false positives
The bare expect_error() also passes when 1 is rejected three times. The test never proves that the prompt accepts valid input.

Actual defect
Three interactive
readline()branches are binary product choices:1means Yes and2means No. The old^[0-9]+$admission accepted values such as0,3, and999even though downstream control flow defines no such choices. Restricting the parser to^[12]$therefore repairs the domain/input invariant directly.A huge decimal can also coerce to
NA_integer_underas.integer(), but that is not by itself evidence of a remotely exploitable MEDIUM DoS. These prompts are local interactive paths and the stronger correctness problem is that the old parser admitted out-of-domain numeric choices at all. This PR no longer makes a severity/RCE/service-availability claim.Repair performed

master@f87c2324f1686135e57d8730c1b0b9420874f300.Current exact head:
14767a86f9989bcc0ad48b48a625046c55d65504.The branch is ahead-only (
ahead_by=7,behind_by=0) with the protected base as its exact merge base.Fresh review found generated contamination unrelated to this three-line input contract:
.Rbuildignore, so package-build/R CMD check evidence could omit the test;.markdownlint.jsondisabled repository-wide Markdown rules for an unrelated R input change;.jules/sentinel.mdgeneralized the narrow prompt invariant into a repository-wide integer-overflow/security doctrine.Normal descendant commits removed those three deltas. The effective diff is now only
R/aFIPC.R, the focused test file, andDESCRIPTIONfor its test-onlymockerydependency.Test contract and remaining evidence
The current test exercises invalid
3, non-numeric input, and a very large decimal against each affected prompt and requires the prompt-specific bounded-attempt failure. Because the positive-path test intentionally proceeds into later psychometric code and accepts a later error, it is not by itself strong enough to prove every valid-path downstream semantic. Before Ready, strengthen that positive contract or provide equivalent causal evidence that both1and2are admitted unchanged at each owned prompt without depending on an unrelated later model failure.Synthetic matrices here are unit-test fixtures only; no psychometric recovery/performance evidence is claimed.
Promotion boundary
Keep Draft until this unchanged head has causal positive/negative prompt evidence, terminal R CMD check, code-quality, security/SAST/OSV/Scorecard evidence, 100% applicable production statement/branch/docstring gates, and current review/thread admission. Queued or predecessor checks are not GREEN. No source-neutral retrigger, self-approval, force update, or gate weakening.
