Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: ๐ต Low ยท up to The prompts now restrict accepted numeric input to 1 or 2 and reject invalid values safely. Direct regression coverage for the interactive paths is still needed to protect that behavior, so the change is mergeable with explicit owner follow-up. ๐ฅ Pre-merge checks | โ 5โ Passed checks (5 passed)

๐ Info: Out-of-range digits now retried instead of erroring immediately
^[12]$ no longer accepts out-of-range digits like 3 or 0; they are retried up to three times before stopping, whereas ^[0-9]+$ returned them immediately to the confirm != 1 check at aFIPC.R. A minor UX change that correctly closes the as.integer() NA-coercion path.

๐จ Severity: HIGH
๐ก Vulnerability: Weak regex validation (
^[0-9]+$) in interactivereadline()prompts allowed large numeric strings to bypass checks.as.integer()coerced these strings intoNA, which crashed the process withmissing value where TRUE/FALSE neededwhen evaluated in subsequent boolean conditions, creating a Denial of Service vulnerability.๐ฏ Impact: An attacker or accidental input could crash the interactive session, requiring the user to restart the process and potentially lose progress.
๐ง Fix: Changed the regex to strictly enforce exact bounds
^[12]$so no invalid numbers can be parsed.โ Verification: Verified via isolated testing scripts demonstrating valid inputs parse properly while exploits are gracefully rejected without crashing.
