kubelet materializes /home/runner/.cache as root when creating the
omp-bazel-repo subPath mountpoint, so bazel's default output_user_root
under it fails with EACCES. Kata jobs now point output_user_root at
RUNNER_TEMP via the bazel-cache rc fragment (pods are single-job
ephemeral; toolchain/crate downloads stay on the PVC repository cache),
and the runner image pre-owns ~/.cache for the next rebake.
- Replaced the napi-cli/cargo-zigbuild/cargo-xwin/sccache build path with
Bazel: rules_rust + crate_universe over Cargo.lock, hermetic zig cc
toolchains (linux-gnu pinned to glibc 2.17, linux-musl), host Xcode for
darwin, and a repo-local hermetic clang-cl + llvm-ml + xwin toolchain for
windows-msvc (bazel/toolchains/msvc).
- All eight shipped addons build as //:natives-<target> via the release
transition in bazel/defs.bzl (opt, thin LTO, cgu=16, stripped, canonical
.node naming); scripts/bazel-natives.ts is the single driver for local
dev and CI.
- Rust validation moved to bazel test + clippy aspects (strict workspace
policy for opted-in crates, default lints elsewhere, mirroring cargo
semantics) and the rustfmt aspect; cargo stays as the dev-iteration
surface, with brush-core/brush-builtins promoted to workspace members
and excluded from cargo dev tasks to keep their historical scope.
- CI caches through an in-cluster bazel-remote action cache (TLS + basic
auth, cluster-internal only); GitHub-hosted runners never touch the
infrastructure and use an actions/cache-backed disk cache instead.
- Deleted the hand-rolled caching machinery: ci-target-cache,
ci-native-artifact-cache, ci-build-native, native-source-hash,
find-native-artifacts, restore-linux-native, native-prewarm workflow,
ensure-* toolchain actions, and all sccache/Swatinem wiring.
- Warm native rebuilds drop from ~20 minutes to seconds; a cold client
with a warm remote cache rebuilds the linux x64 pair in ~2.5 minutes.
- Enhanced CI workflows and GitHub actions to support native artifact caching and parallel builds.
- Added composite actions and scripts for computing sources, finding artifacts, and managing caches.
- Updated infrastructure documentation and runner deployment scripts with revised resource limits.
- Pinned to the same versions as .github/actions/ensure-cmake (cmake 4.1.2, ninja 1.13.1), which now no-ops on the preloaded image.
- Extended both reload smoke-test tool lists with cmake/ninja.
- Rolled out as omp-kata-runner:2026-07-24-113811.
- Updated bun-install action to set mounted cache mode and use PVC cache paths.
- Removed RustFS Bun restore/save and maintenance scripts, replacing them with mounted cache setup.
- Removed zstd from runner image installation and baked-tool verification checks.
- Updated infra docs to describe split caching with RustFS for sccache and PVC for Bun/Cargo.
- Added composite GitHub actions to ensure rust toolchains and cargo helpers.
- Added a kata-native build action with variant checks and platform artifact uploads.
- Reworked CI matrices to split native cross-platform jobs and gate releases accordingly.
- Updated runner bootstrap and image to preinstall pinned build tools for CI consistency.
