Review

Findings

Medium

• [stale-reference] Dockerfile:19 — Dockerfile still uses golang:1.26.3 base image while .tool-versions is bumped to 1.26.4, creating version skew between local development (asdf/mise) and container builds.
  Remediation: Update the FROM line to golang:1.26.4, or have Renovate/Mintmaker handle Dockerfile updates in the same PR.

• [stale-reference] Dockerfile.dist:19 — Dockerfile.dist still pins go-toolset:1.26.3 (with digest). The Go toolchain version is now inconsistent with .tool-versions (1.26.4). The UBI image tag for 1.26.4 may not yet be available.
  Remediation: Update the tag to 1.26.4 with the correct digest once the UBI image is published.

Low

• [stale-reference] go.mod:3 — Root go.mod still declares go 1.26.3. The go directive is a minimum version floor, so this is cosmetic — Go 1.26.4 builds modules declaring go 1.26.3 without issue.
  Remediation: Run go mod tidy with Go 1.26.4.

• [stale-reference] tools/go.mod:3, tools/kubectl/go.mod:3, acceptance/go.mod:3 — All secondary go.mod files still declare go 1.26.3. Same cosmetic concern as root go.mod.
  Remediation: Update the go directive to 1.26.4 in each module.
