🔍 Prompt tests bypass production code
These assertions duplicate the regex instead of invoking autoFIPC(). They can pass after a prompt diverges and reintroduces the coercion failure.

🚨 Severity: CRITICAL
💡 Vulnerability: Interactive
readline()prompts for boolean choices used a weak regular expression (^[0-9]+$). This allowed out-of-bounds large integer inputs which, when coerced viaas.integer(), resulted inNAinstead of numerical values. This broke subsequentifcondition execution, creating a Denial of Service crash.🎯 Impact: Exploiting this bug would crash the interactive session or script during parameter calibration input queries, disrupting the workflow.
🔧 Fix: Replaced the unbounded
^[0-9]+$regex with a strictly bounded menu expectation:^[12]$. Added coverage intest-autoFIPC.R.✅ Verification: Verified all unit tests and specific security regex unit tests executed using
