The backend-detection shell block in .github/actions/bun-install/action.yml was missing its closing fi, so every job that touched the composite failed immediately with . Restore the RustFS/GHA branch correctly and validate with YAML parse + bash -n.
- Updated the bun-install composite action to detect preinstalled Bun and only fetch it when missing.
- Added cache-backend detection and wiring so Bun dependencies use RustFS cache when SCCACHE credentials are present.
- Conditionally skipped rust-cache in build-native and CI jobs when shared sccache runners are available, relying on the existing RustFS/sccache layer instead.
- Added beforeEach and afterEach hooks in mnemopi tests to set and clear MNEMOPI_NO_EMBEDDINGS so embeddings are skipped during those runs.
- Updated the bun-install cache script to archive only node_modules paths that exist as directories.
- Updated CI dependency install flow to share bun cache orchestration across jobs.
- Added RustFS-backed bun cache restore/save script keyed by bun.lock hash.
Self-hosted omp-kata runners now inject a shared S3 (RustFS, in-cluster)
sccache backend via pod env (SCCACHE_BUCKET/ENDPOINT/REGION + AWS creds).
The Enable-sccache step branches on SCCACHE_BUCKET: when set, sccache reads
the S3 config from the inherited environment; otherwise GitHub-hosted
runners (macOS, ubuntu-arm) keep the GHA cache backend since they can't
reach the private RustFS.
- Added a setup-system-deps action with preloaded-runner guards and apt fallbacks.
- Updated CI workflows to download Linux x64 native artifacts and gate on native job success.
- Renamed coding-agent fast mode to singleton in scripts and test partitioning logic.
- Added settings test-state begin/restore helpers with recursive cleanup in affected tests.
- Renamed the gate and native jobs in CI for consistent release naming.
- Renamed reusable-artifact output keys for native lookup compatibility.
- Rewired release and test jobs to read tags, flags, and hashes from metadata outputs.
- Removed `tags: ["v*"]` trigger; release now fires from the single atomic `main` push that carries the tag.
- Replaced `gate.skip` with `gate.is-release` and `gate.release-tag` so downstream jobs detect the tag via `git tag --points-at HEAD`.
- Passed `release-tag` explicitly to release steps (gh-release, curl, release notes) since `github.ref` is now `refs/heads/main`, not the tag.
- Fixed rust-cache key collision on macOS x64 by setting `RUSTFLAGS` (target-cpu) before cache restore and including the native source hash in the shared key.
- sccache silently skips caching when incremental compilation is enabled, making the wrapper a no-op.
- Applied fix to both the shared build-native action and the CI workflow setup step.
- Updated the build-native action to install cargo-zigbuild for non-MSVC targets and cargo-xwin with LLVM tooling for MSVC targets.
- Removed the fixed aarch64 linker variable and narrowed Rust test execution to skip duplicate macOS runs.
- Reworked CI matrices to build win32-x64 artifacts on ubuntu with x86_64-pc-windows-msvc and simplified smoke testing to skip those Windows binaries via matrix gating.
- Updated `rust-hash` to return separate `linux-run-id` and `release-run-id` outputs by checking each prior run for required native artifacts.
- Rewired `native_linux` and `native_release` gating to use those outputs, enabling Linux cache reuse on main and release pre-warm only when all cross-platform artifacts are present.
- Enabled sccache in both the shared native build action and CI setup, and excluded macOS workspace Rust tests from the generic native test step due to duplicated coverage.
- Extracted repeated build steps into a reusable `build-native` composite action.
- Split `native` into `native_linux` (runs on every PR) and `native_release` (tags only).
- Release jobs now always use same-run artifacts, removing cross-run artifact resolution logic.
