PR created automatically by Jules for task 17559475454595105316 started by @seonghobae

This commit introduces a security enhancement to the `autoFIPC` function by adding rigorous type checking for main input parameters (`newformXData`, `oldformYData`, `newformCommonItemNames`, `itemtype`) to prevent potential state leaks and unhandled downstream exceptions that could occur when malformed inputs are dynamically evaluated. Furthermore, the fix adds existential checks on `oldFormModel` and `newFormModel` immediately following their `try()` estimation blocks to ensure failures fast-fail cleanly rather than crashing internally on missing property access (`@OptimInfo`). Test cases were updated to reflect these security restrictions.

πŸ‘‹ Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a πŸ‘€ 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 @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

Brings the scoped Trivy private-key suppression (trivy.yaml + .trivyignore.yaml, #116) so the required trivy-fs gate stops failing on the vendored openssl doc example key (verified false positive).

Stack recheck for current head edd5e68ca36205f1452f341350cfb5d104ccfa24, evaluated after pending #93 (07dc8dcafcf4db35dd210c83411861dec62473dc) and #108 (6fab9cd26e060f59a8e625b9d9c51538f9755854) on current origin/master:

  • Local merge order origin/master -> #93 -> #108 -> #111 was clean.
  • git diff --check origin/master...HEAD passed.
  • R CMD INSTALL . passed using local R 4.4.1.
  • Full testthat suite passed: 34 passes, 0 failures/warnings/skips.
  • Exact CI markdownlint command covered 14 files with 0 errors.

This preserves the Fixed Parameter Item Calibration documentation/evidence path, true-parameter reproduction tests, and the SE=TRUE Hessian/vcov/secondordertest stability checks covered by the full suite.

No branch changes were pushed; this is validation-only while #93 remains the queue head.

This keeps the negative-grep fix compatible with the input-validation branch and preserves the Fixed Parameter Item Calibration documentation/evidence path, true-parameter reproduction tests, and SE=TRUE Hessian/vcov/secondordertest stability coverage.

#93 remains the queue head; this is validation-only and does not change merge order.

The previous commit added a trivy workflow in CI which failed due to a mock private key found inside `packrat/lib/x86_64-pc-linux-gnu/3.4.1/openssl/doc/keys.html`. This is a vendor mock file not used in production. We configured `trivy.yaml` to skip scanning the `packrat/lib` directory.

Restacked this PR onto the current #108 head 8347e2a4cc8056dc536881e89c4831a0c87e1e75 with merge commit 9cbc785f9eb8400a49c442d11f3fc11e1180ff2d.

Validation on the restacked head:

  • git diff --check origin/master...HEAD passed.
  • R CMD INSTALL . passed with local R 4.4.1.
  • testthat::test_dir('tests/testthat') passed: 34 pass, 0 failures/warnings/skips.
  • FIPC-focused tests stayed green: test-autoFIPC.R 6 pass and test-fixed-parameter-calibration.R 23 pass.

This keeps #108 as the merge queue head and preserves the Fixed Parameter Item Calibration docs/evidence path, true-parameter reproduction tests, and SE=TRUE Hessian/vcov/secondordertest stability coverage while making #111 ready for the post-#108 base.

OpenCode Review Overview

  • Head SHA: 0a9db20bdb59be1685db4d1431e187833efab302
  • Workflow run: 29060912946
  • Workflow attempt: 1
  • Gate result: APPROVE (approval step)

Pull request overview

OpenCode reviewed the current-head bounded evidence and found no blocking issues.

Findings

No blocking findings.

Summary

Approval sufficiency: bounded evidence supplied affirmative approval evidence for changed files, coverage/docstring posture, risk surfaces, and current-head verification; approval is not based merely on the absence of known blockers.
Verification posture: CodeGraph evidence was initialized and bounded current-head evidence reviewed for changed-file evidence including .jules/sentinel.md, docs/fixed-parameter-item-calibration.md.
Linter/static: workflow/static review evidence is bounded by the current-head GitHub Checks gate and changed-file evidence.
TDD/regression: coverage execution evidence and focused changed hunks were reviewed from bounded-review-evidence.md.
Coverage: coverage execution evidence reports supported repository test suites passed.
Docstring coverage: coverage execution evidence reports configured repository docstring gates passed or docstring coverage was advisory.
DAG: CodeGraph/source-backed behavior map connects .jules/sentinel.md to the affected review, runtime, or workflow path and required checks.
PoC/execution: coverage-evidence job executed on the current head and reported PASS.
DDD/domain: workflow and repository-governance invariants were reviewed against changed files in bounded evidence.
CDD/context: CodeGraph evidence, changed-file history, and focused hunks were reviewed from bounded-review-evidence.md.
Similar issues: changed-file history evidence was reviewed for comparable local precedents.
Claim/concept check: bounded evidence, repository source, current-head workflow evidence, and, where numeric, scientific, statistical, or literature-backed claims are affected, original-paper/formula evidence and parameter-recovery expectations were used for claims.
Standards search: standards and external-source checks are delegated to configured OpenCode web_search/Context7/DeepWiki sources when applicable; no evidence-backed standards blocker is present in bounded evidence.
Compatibility/convention: changed workflow/script conventions, object naming, and reserved-word safety for schema/API/config/code surfaces were checked in bounded evidence.
Breaking-change/backcompat: deployment evidence and changed-file history were checked for backward-compatibility risk.
Performance: changed surfaces were checked for performance risk in bounded evidence.
Developer experience: changed automation, review, test, setup, and maintenance surfaces were checked for helpful or obstructive DX impact in bounded evidence.
User experience: connected user, operator, API, CLI, documentation, review-comment, status-check, rendering, and workflow-reader behavior was checked for contradictions against code, docs, and tests in bounded evidence.
Visual/DOM: Playwright visual, DOM locator, ARIA snapshot, console, and responsive evidence were checked when a web UI surface was present; for non-web surfaces, API/CLI/log/docs/workflow interaction evidence was reviewed instead.
Accessibility/i18n: accessibility, localization, and human-readable text surfaces were checked where UI, CLI, API message, docs, logs, or review text changed.
Supply-chain/license: dependency, package, model, container, and external-tool changes were checked in bounded evidence.
Packaging: package, build, test, lint, and security contracts were checked in bounded evidence.
Security/privacy: workflow-token, review-gate, and repository-automation security/privacy boundaries were checked in bounded evidence.

  • Result: APPROVE
  • Reason: Critical security fix with verified test environment
  • Head SHA: 0a9db20bdb59be1685db4d1431e187833efab302
