Walkthrough

The configured Ruby version changes from 3.4 to 4.0.

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to 7ae78

The Windows dependency-bump task has a Ruby 4.0 package available. No identified issue blocks this version update.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 7ae78

No expanded permissions or verified vulnerability was identified. The main concern is runtime alignment: dependency updates now select Ruby 4.0, but the Windows CI test image is refreshed independently and may still use an older Ruby.

Retained concerns

• Low · reliability · inferred: Ruby 4.0 dependency selection can advance without a matching refresh of the CI test image. The existing image-build triggers exclude .ruby-version, while dependency updates select ruby-4.0 immediately. This creates a possible validation-runtime mismatch before repository publication, weakening the assurance provided by the test gate. The coupling weakness predates this PR; the new version selection exposes it. Actual deployed runtime drift is unverified.

Security review details

Security Blast Radius

• inferred — The demonstrated exposure is within existing CI execution and dependency publication. Changed-runtime code executes through existing workflow and pipeline authority; the inspected change does not add a tenant boundary, privileged destination, or credential grant.

Trust Boundaries and Controls

• observed — Runtime selection remains repository-controlled and is passed to an existing external task. Tests remain upstream of credential-backed repository writes; no new local publication path bypasses those stages.

Resilience and Maintainability Implications

• inferred — The existing ordering contains ordinary update or test failures before publication. It does not demonstrate atomic publication across both repository puts, or recovery safety inside the external task. Those contracts are unchanged and remain incompletely verified rather than established PR-introduced failures.
