Dockerfiles:
- Merge rustup target add and component add into one chained RUN with
|| true guard, making it safe if rustfmt/clippy are already present
in the base image's default toolchain profile (rust:1.88-slim default
profile includes both; the guard is belt-and-suspenders)
test.yml:
- Add --locked to cargo clippy and cargo test to enforce Cargo.lock
during CI, preventing silent dependency upgrades
Not addressed (accepted/out of scope):
- git in images: already installed in all three Dockerfiles (lines 19,
13, 15 respectively) — reviewer finding was incorrect
- HTTP registry: accepted risk for air-gapped self-hosted infrastructure
- Image signing (Cosign): no infrastructure in place yet
- Hardcoded registry IP: consistent with project-wide pattern
