Two things, same file:

  • rust:1.97.0-slim-bookworm floated by digest. Pinned at what the tag resolves to today (image unchanged), as its own ARG because RUST_VERSION doubles as a rustup toolchain name where a digest suffix would corrupt it. Both ARGs carry the same Renovate depName so they move in one PR.
  • A latent no-op: RUST_VERSION was never redeclared after FROM, so step 1.6's rustup default ${RUST_VERSION} has been running as a bare rustup default — which prints the default instead of setting it. Green only because the base image's default happens to match. Redeclared, so the pin actually operates.

- RUST_VERSION was never redeclared after FROM, so step 1.6's
  'rustup default ${RUST_VERSION}' has been running as a bare
  'rustup default' — which PRINTS the default instead of setting it. Green
  only because the base image's default happens to match. Redeclared, so the
