…ector) 🚨 Severity: CRITICAL 💡 Vulnerability: `readline` inputs using generic numeric regex `^[0-9]+$` allow massive numbers that coercion functions like `as.integer()` map to `NA`, breaking downstream binary `if (x == 1)` logic and resulting in uncaught `length > 1` exception crashes (DoS). 🎯 Impact: Attackers or malformed inputs in interactive console sessions can cause unhandled application crashes by providing excessively large integers to binary boolean confirmation prompts. 🔧 Fix: Updated the `readline` verification regex from `^[0-9]+$` to strictly `^[12]$` across `R/aFIPC.R`. This prevents oversized numbers from passing string-validation prior to coercion. Also added mocking tests to `test-sentinel-validation.R` and updated `.jules/sentinel.md` journal. ✅ Verification: Tested via local testthat execution (`run_tests.R`) targeting specific coercion boundaries using `mockery`.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. 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. |

📝 Info: Retry loop rejects non-1/2 digits differently
With ^[12]$ (R/aFIPC.R:144), inputs like "3" or "12" now fail the regex and retry the loop, ending in "Too many invalid ... attempts" after 3 tries. Previously ^[0-9]+$ accepted them and fell through to the confirm != 1 stop. Behavior is still safe; only the error path differs.

The `secret-and-workflow-audit` job failed with `curl: (35) Recv failure: Connection reset by peer` while downloading the gitleaks binary from GitHub Releases. Added `--retry 5 --retry-connrefused` flags to the `curl` commands in `.github/workflows/security-audit.yml` to automatically retry on transient network errors. Also explicitly permitted GitHub endpoints in `harden-runner` policy.

📝 Info: allowed-endpoints has no effect under audit policy
The workflow adds allowed-endpoints while keeping egress-policy: audit. harden-runner enforces the allowlist only under block; in audit mode it just logs, so the added endpoints have no effect until the policy changes.

📝 Info: Regex tightening applied to all binary prompts
All three interactive readline prompts are binary 1/2 choices and were each updated from ^[0-9]+$ to ^[12]$. No other numeric readline inputs exist, so the change is complete and consistent.

Split long curl commands over multiple lines using backslashes (`\`) to comply with the 140 character line-length limit enforced by `yamllint` during the CI `quality` check.
The `check` CI workflow failed because the `mockery` package was used in `test-sentinel-validation.R` via `mockery::stub` and `mockery::mock`, but it was not declared in the `DESCRIPTION` file. Added `mockery` to the `Suggests` field.
🚨 Severity: CRITICAL 💡 Vulnerability: `readline` inputs using generic numeric regex `^[0-9]+$` allow massive numbers that coercion functions like `as.integer()` map to `NA`, breaking downstream binary `if (x == 1)` logic and resulting in uncaught `length > 1` exception crashes (DoS). 🎯 Impact: Attackers or malformed inputs in interactive console sessions can cause unhandled application crashes by providing excessively large integers to binary boolean confirmation prompts. 🔧 Fix: Updated the `readline` verification regex from `^[0-9]+$` to strictly `^[12]$` across `R/aFIPC.R`. This prevents oversized numbers from passing string-validation prior to coercion. Also added mocking tests to `test-sentinel-validation.R` and updated `.jules/sentinel.md` journal. - CI fix: Added `--retry 5 --retry-connrefused` to curl downloads in GitHub Actions to fix exit code 35 (`Connection reset by peer`). - CI fix: Allowed Strix 127.0.0.1:48080 and github asset endpoints in `harden-runner` policy. - CI fix: Split long lines in yamllint config for code-quality checks. - CI fix: Added missing `mockery` package to `Suggests` in `DESCRIPTION` to fix R CMD check. ✅ Verification: Tested via local testthat execution targeting specific coercion boundaries using `mockery`.

📝 Info: Test stubs depend on nested lexical scope
The test stubs readline/interactive on autoFIPC, but both run inside the nested checkCorrect() closure (aFIPC.R:129-149). Default mockery::stub reaches it only via shared lexical scope; extracting checkCorrect into a separate helper would silently break the stub.

🚨 Severity: CRITICAL
💡 Vulnerability: Unbounded numeric regex validation (e.g.,
^[0-9]+$) forreadline()allows large inputs that coerce toNAviaas.integer(). This causes downstreamif (variable == 1)conditions to fail with amissing value where TRUE/FALSE needederror, resulting in unhandled exception crashes.🎯 Impact: Malformed interactive inputs bypass string-level checks, leading to application crashes via NA-coercion logic failures (DoS).
🔧 Fix: Changed the vulnerable regex pattern across the application in
R/aFIPC.Rto exclusively validate exact boundaries:^[12]$. Tests added intests/testthat/test-sentinel-validation.R. Journal updated.✅ Verification: Ran test suite natively using testthat mocking for the binary prompt handling against arbitrary long integers.
