Weak regex validation in `readline()` inputs allowed arbitrary large numbers to be entered, which would coerce to `NA` via `as.integer()`. This can lead to unexpected conditions and DoS via unhandled exceptions. This commit patches the vulnerable prompts by strictly binding the regex validation to exactly `1` or `2`.

I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The prompts now accept only 1 or 2, preventing oversized numeric input from reaching integer conversion. The remaining risk is low: the changed interactive paths need focused regression tests to preserve this behavior. Possibly related PRs

| ## 2024-07-12 - Fix weak regex validation for integer coercion | ||
| **Vulnerability:** Weak regex validation (`^[0-9]+$`) for `readline()` inputs allows extremely large numbers (e.g. `9999999999999999999999`) to be parsed. When coerced via `as.integer()`, these large strings turn into `NA` rather than numbers, breaking downstream `if` conditions and causing unhandled exceptions/DoS vulnerabilities. | ||
| **Learning:** R's `as.integer()` fails silently with `NA` (along with a warning) when it encounters numbers larger than a 32-bit integer limits, making broad regex digit validation insufficient for inputs meant to be coerced to integers. | ||
| **Prevention:** Use strictly bounded exact-match regex (e.g., `^[12]$`) to validate inputs intended for discrete integer coercion prior to calling `as.integer()`. |

변경된 대화형 입력 경로를 테스트로 고정해 주세요.
이번 변경은 readline()의 동작을 바꿉니다. 제공된 테스트는 비대화형 오류와 confirmCommonItems = TRUE 경로만 검증합니다. R/aFIPC.R의 Line 144, Line 174, Line 393에 있는 대화형 경로는 실행하지 않습니다. 1과 2는 통과하고 0, 12, 매우 큰 숫자, 빈 입력은 재시도되며 세 번 실패하면 오류가 발생하는 테스트 또는 fixture를 추가하세요. as.integer() 호출 전에 범위 검증이 유지되는지 확인해야 합니다.
Also applies to: 174-174, 393-393

Closed only after verified successor review. The valid production delta here is exactly the same three
R/aFIPC.Rmenu-admission changes now carried by canonical Draft #330 on exact head4b38d796e411e4e87c5bf8e9d0ea2f1c65a589fe. #330 additionally has production-path regressions that execute exportedautoFIPC()through the prompt boundary. The generated.jules/sentinel.mdentry in this PR is not independent product value: it generalized a local binary-menu invariant into a repository-wide security doctrine and attached unsupported CRITICAL/DoS severity. #330 deliberately restores canonical protected Sentinel guidance instead. No valid test, fixture, contract, or product semantic remains unique to #326; this is verified-successor closure, not a merge.
