# Static analysis (code scanning) for the Rust workspace and the Angular
# frontend. Findings surface under the repository's Security > Code scanning
# tab and as PR annotations.

# Runners: matches the rest of CI on the self-hosted fleet so the runner-policy
# gate passes. Both languages use buildless extraction (build-mode: none), so
# no compiler/toolchain step is needed; a single label set covers both.
