Important Approval pendingCodeRabbit has no unresolved comments, but it could not review the latest commit because the review limit was reached. Follow the review guidance in this comment to continue. 📝 WalkthroughWalkthroughThe change adds a Bash guard that detects tools installed by CI package-manager steps and also vendored under dependency directories. Bats tests cover detection, exclusions, clean trees, and invalid paths. The lint workflow runs the new tests. ChangesVendored tool overlap guard
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to This PR adds a CI guard for redundant vendored tools, but its workflow parsing may occasionally flag unrelated text or miss multiline installation commands, and the policy can be silently disabled if its test file is removed or renamed. The change is mergeable with explicit owner awareness and follow-up for these bounded risks. Sequence Diagram(s)sequenceDiagram

Note @don-petry I reviewed this PR and no code changes were needed, but it still has blocking checks or reviews (failing or cancelled checks, or changes-requested reviews), so I cannot mark it done yet. I'll re-check automatically. |

Code Review
This pull request introduces a new guard script, check-vendored-installed-tools.sh, along with corresponding BATS tests, to prevent committing vendored copies of tools that are already installed by CI workflows. The feedback highlights several improvement opportunities: ensuring list_tree_files correctly identifies the git root when run inside temporary directories, replacing non-POSIX \b word boundaries in regular expressions for better portability, simplifying redundant flags in grep, and using synthetic workflow files in tests to avoid dependency on the real lint.yml file.

Summary
Adds scripts/check-vendored-installed-tools.sh (131 lines), a narrow guard that fails CI when a tool CI already installs via a package manager (apt-get/npm/pip; allowlist: bats, yq, markdownlint-cli2) is also committed as a vendored copy under node_modules/, vendor/, or .venv/. Includes 7 bats tests covering the #1449 fixture, narrowness/no-false-positive cases, line-continuation installs, and invalid-tree usage; wired into lint.yml's existing run-bats.sh invocation (one-line change). Triage assessment confirmed: scope is exactly the enforceable sliver described in #1541.
Linked issue analysis
Closes #1541. All 4 acceptance criteria are substantively addressed: (1) guard fails when a CI-installed tool is also vendored under a dependency-manager directory; (2) deliberately narrow — static allowlist plus actual-install-step overlap, verified by no-false-positive tests (vendored-without-install, first-party asset outside dep dirs, install-without-vendored); (3) the #1449 node_modules/bats-alongside-apt-get fixture fails and the current clean tree passes; (4) wired into lint.yml alongside the existing bats suite. Matches the issue's Dev Notes: simple static tuples, no general dependency resolver.
Findings
No blocking findings. Prior bot review findings were all addressed and their threads resolved: multiline install steps are handled by folding shell line-continuations before matching (codeant-ai Major); GNU-only \b word boundaries were replaced with POSIX ERE classes (gemini medium); git-work-tree detection checks for $TREE/.git directly so nested non-git fixture trees fall back to a filesystem walk (gemini high). Script uses set -euo pipefail, no eval/injection surface, shellcheck passes. Secret-scanning MCP tool unavailable in this environment; gitleaks CI check passed. Workflow change is a single test-file addition to an existing run-bats.sh list — no Actions security smells.
CI status
All substantive checks green: shellcheck, bats, unit-tests, Lint, gitleaks secret scan, CodeQL (actions + python), SonarCloud quality gate, agent-shield, actionlint, and all repo guard checks. Cancelled entries in the rollup are superseded dev-lead/concurrency runs on earlier commits; the latest review and Dismiss runs succeeded. CodeRabbit approved; all review threads resolved; no unanswered human-reviewer questions.

Summary
Adds a narrow bats guard (scripts/check-vendored-installed-tools.sh + 7-test bats suite) that fails CI when a tool already installed by a workflow package-manager step (apt-get/npm/pip) is also committed as a vendored copy under node_modules/, vendor/, or .venv/ — the exact #1449 failure signature. Wired into lint.yml via a one-line addition to the existing run-bats.sh list. Script is defensive (set -euo pipefail, POSIX ERE word boundaries, git-tracked-files scan with filesystem fallback for fixture trees, line-continuation folding) and all six bot review findings were fixed and resolved.
Linked issue analysis
Closes #1541 ([Phase 4] Bats guard: vendored copy of a CI-installed tool, split from #1468 AC 3). All four acceptance criteria are substantively addressed: (1) install-step tool extraction from .github/workflows/** including installs split across shell line-continuations; (2) narrow scoping — fires only on the CI-installs-X AND vendored-copy-of-X overlap, with tests proving first-party assets and unmatched vendored dirs pass; (3) the #1449 node_modules/bats fixture fails red and the current clean tree passes green; (4) wired into lint.yml alongside the existing bats suite.
Findings
No blocking findings. All six prior bot review threads (codeant-ai, gemini-code-assist, coderabbitai) are resolved with verified fixes in the current head: multiline install detection via awk continuation-folding, .git-presence gating for nested temp trees, POSIX ERE word boundaries replacing GNU-only \b, removal of the redundant grep flag, and self-contained synthetic test fixtures. No security anti-patterns; the lint.yml change adds no new actions, permissions, or untrusted input. MCP secret-scanning tool unavailable in this session; the gitleaks CI check passed.
CI status
All current checks green: shellcheck/ShellCheck, bats, unit-tests, Lint, CodeQL (actions + python), Agent Security Scan, agent-shield, Secret scan (gitleaks), SonarCloud, actionlint, and all org guard checks pass at the reviewed commit. Cancelled entries in the rollup are superseded earlier runs.
