# CodeQL security analysis — advanced setup.
#
# GitHub's dynamically-configured scanning only analyzes the no-build
# languages it supports (JS/TS, Go, Python), which silently skips the Rust
# reference implementation — including the sdks/c crate, whose actual code
# is Rust behind a C ABI. This workflow adds Rust (CodeQL public preview,
# build-mode: none) and Actions workflow scanning alongside the big three.
#
# c-cpp is deliberately absent: the only C sources are the generated header
# and one example; the implementation CodeQL should look at is the Rust.
#
# go/javascript-typescript/python overlap with the dynamic scanning is
# intentional, not accidental: the Code Quality product runs quality
# queries, while this workflow runs the security suite — those three
# languages had no security-suite analysis before this workflow. Alert
# dedup handles any rule overlap.
