## What changed Replace fixed release pins for app-server/exec-server compatibility tests with the latest stable version and the stable release published closest to 60 days ago. Exclude drafts and prereleases, and prefer the higher version when publication dates are equally close. Resolve release versions and SHA-256 asset digests before Linux Bazel CI runs, passing them through `CODEX_COMPAT_RELEASES` to the release archive repositories. Reuse the argument comment lint action so it also prepares compatibility releases. Add bounded retries for transient GitHub release reads. ## Testing Add unit coverage for stable release filtering, version ordering, nearest publication dates, tie-breaking, and deduplication when both selections resolve to the same release.

Workflow Strategy
The workflows in this directory are split so that pull requests get fast, review-friendly signal while main still gets the full cross-platform verification pass.
Pull Requests
- Required checks run against GitHub's synthetic merge commit, not the pull
request head alone. This includes changes already on
mainand catches conflicts before they reach the branch. bazel.ymlis the main pre-merge verification path for Rust code. It runs Bazeltestand Bazelclippyon the supported Bazel targets, including the generated Rust test binaries needed to lint inline#[cfg(test)]code.rust-ci.ymlkeeps the Cargo-native PR checks intentionally small:cargo fmt --checkcargo shearargument-comment-linton Linux, macOS, and Windowstools/argument-comment-lintpackage tests when the lint or its workflow wiring changes
Post-Merge On main
bazel.ymlalso runs on pushes tomain. This re-verifies the merged Bazel path and helps keep the BuildBuddy caches warm.rust-ci-full.ymlis the full Cargo-native verification workflow. It keeps the heavier checks off the PR path while still validating them after merge:- the full Cargo
clippymatrix - the full Cargo
nextestmatrix via per-platform archive-backed shards - Windows ARM64 nextest archives cross-compiled on Windows x64, then replayed on native Windows ARM64 shards
- release-profile Cargo builds
- cross-platform
argument-comment-lint - Linux remote-env tests
- the full Cargo
Rule Of Thumb
- If a build/test/clippy check can be expressed in Bazel, prefer putting the PR-time version in
bazel.yml. - Keep
rust-ci.ymlfast enough that it usually does not dominate PR latency. - Reserve
rust-ci-full.ymlfor heavyweight Cargo-native coverage that Bazel does not replace yet.
