Summary

  • Make Cargo dev a fast, debuggable profile and add prod for optimized builds with parallel codegen.
  • Route local and release builds through the pinned Mr Boxington cache where configured.
  • Align test workflows and helpers with the debug output path, and split Rust suites into measured fast, mid, and slow lanes with explicit timeboxes.
  • Pin the October 4 Rust nightly and update the build guidance.
  • Add the pinned run-local-ci dev dependency.

This PR is separate from action ownership (#12055) and standalone policy checks (#12054).

Validation

  • node scripts/soak/soak.mts --check
  • node scripts/soak/external-tools.mts --check
  • git diff --check

The Cargo/Rust build and test matrix is left to CI.

Summary by CodeRabbit

  • Build & Tooling
    • Added dev and prod build profiles with matching commands for local development and optimized builds.
    • Updated release and package builds to use the prod profile.
    • Updated the Rust toolchain used for builds and checks.
  • Testing & CI
    • Organized Rust tests into timeboxed lanes and adjusted CI test scopes and time limits.
  • Bug Fixes
    • Improved handling of unexpected data when reading gzip streams.
  • Documentation
    • Updated build and testing guides with the new profiles, commands, and CI test lanes.

📝 Walkthrough

Walkthrough

The changes define dev and prod Cargo profiles and update local, production, and CI build commands to use them. They also update Rust nightly pins, revise CI test scopes and timeouts, and align build and test scripts with the profiles’ output directories.

Changes

Build profiles and CI

Layer / File(s) Summary
Define profiles and local build commands
Cargo.toml, Makefile, external-tools.json, rust-toolchain.toml, CLAUDE.md, CONTRIBUTING.md, docs/src/contributing/building.md, crates/perry/src/panic_profile_contract.rs, crates/perry/tests/function_apply_dynamic_args_eval_surface.rs, changelog.d/12056-build-profiles-ci-lanes.md
Cargo adds the dev profile and prod profile, while retaining compatibility profiles. The Makefile adds tool installation and dev/prod build targets. Tool pins, profile checks, and build guidance are updated.
Move production builds to prod
.github/workflows/release-packages.yml, scripts/build_core_runtime.sh, scripts/build_linux_glibc_2_31.sh, scripts/build_linux_musl.sh, scripts/cargo_timing_summary.py, scripts/publish/brew/formula.mts
Release workflows and build scripts use mbx with the prod profile where specified. Artifact eviction, staging, and installation paths change from dist or release to prod.
Update CI toolchains and test lanes
.github/workflows/*, docs/src/testing/ci-tiers.md, scripts/ci_plan.py, package.json
Workflow toolchain pins change to nightly 2026-10-04. The test workflow updates scope, timeout, and Windows profile behavior. CI tier documentation and the sweep description are revised.
Align build and test artifact paths
scripts/check_gc_header_constants.py, scripts/node_compat_matrix.mjs, scripts/run_windows_runtime_regressions.py, scripts/test-*.mjs
Regression scripts use target/debug as the default compiler or runtime path where applicable. Runtime profile handling accepts dev and prod, and maps dev runtime archives to Cargo’s debug output directory.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Feature

Merge Risk: 🟠 High · up to cdf85

This change moves release builds to a new profile and a new build tool. The release workflow is only partly updated. Later steps still look for artifacts in the old location, and the new build tool is never installed on the macOS release runners. As merged, release packaging would fail. Update the artifact paths and add the pinned tool installation before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to cdf85

Production builds now produce prod artifacts, but several verification, packaging, and signing steps still consume dist artifacts. Clean releases can fail, while leftover older outputs could be treated as current release artifacts. The new build-cache dependency also needs confirmed release-runner provisioning and trust controls.

Retained concerns

  • Medium · security · inferred: The prod migration breaks the identity link between the current build and trusted release outputs. Compilation refreshes prod, while verification, Unix packaging, cross-bundle staging, and CLI-update manifest signing still select dist. Missing legacy outputs cause failures; if usable legacy outputs remain, symbol checks do not establish that they belong to the current candidate. Those outputs could be packaged, and a legacy compiler could execute with the update-signing secret. Actual stale-cache contents or attacker control were not established.
Security review details

Security Blast Radius

  • inferred — The affected boundary is repository-wide release provenance: compiler binaries and runtime, stdlib, extension, and cross-target libraries intended for distribution. It is not a newly reachable tenant-facing endpoint. A wrong trusted release artifact could affect downstream users of the affected platform packages; cache-writer privileges and independently attackable cache scope remain unknown.

Security Findings and Attack Paths

  • inferred — A conditional path exists from retained legacy dist outputs through sentinel-only validation into release packaging and manifest signing. Malicious exploitation would require control over an accepted legacy executable or artifact, which was not demonstrated. Ordinary stale-output reuse could nevertheless associate older bytes with a new release. This is an artifact-identity concern, not a verified cache-poisoning or secret-exfiltration finding.

Trust Boundaries and Controls

  • observed — Release initiation remains through published-release events or manual dispatch, with existing preflight/test gates. The Rust cache action is pinned, prod workspace fingerprints are evicted, and runtime symbols are checked when inspection tools are available. These controls do not bind legacy dist outputs to the current compilation. The symbol guard also skips successfully when no supported symbol tool is available.

Hardening Proposals

  • proposed — Use one profile-derived artifact selection contract across compilation, verification, container handoff, staging, and signing. Exclude legacy outputs from release inputs and bind consumed artifacts to the candidate, target, profile, and runtime variant. Provision the pinned cache executable explicitly in release jobs and document cache authorization and integrity controls.

official GitHub hosted runner image software inventory macOS 15 Ubuntu 24.04 Windows mbx Cargo package preinstalled

💡 Result:

**Short answer:** I can’t confirm that the `mbx` Cargo package is preinstalled on these GitHub-hosted images. The official inventories document installed tools, but the available macOS inventory doesn’t list `mbx`; I couldn’t verify the Ubuntu 24.04 and Windows inventories for that package either. ([github.com](https://github.com/actions/runner-images/blob/main/images/macos/macos-15-Readme.md?utm_cta=website-workload-data-engineering-extensible-pipeline-webinar&utm_source=openai))

GitHub’s official runner-images repository is the source for the inventories, and GitHub says each workflow’s **Set up job → Runner Image → Included Software** link identifies the tools on the exact runner used. Because images update, check that link for your run—or install `mbx` explicitly rather than relying on it being present. ([github.com](https://github.com/actions/runner-images?utm_source=openai))

Install the pinned mbx before the release build steps.

No provisioning precedes the first mbx call in any of these jobs:

  • prime-macos-x86_64-cache: line 484.
  • build: line 688.
  • build-cross: line 1450.

The build and build-cross macOS legs can fail with command not found, failing their build jobs. The cache-prime job is marked continue-on-error, so its failure is non-gating.

🗄️ Data Integrity & Integration | 🔴 Critical | 🏗️ Heavy lift

Move every release-artifact consumer to prod.

These builds now write to target/<triple>/prod, but this workflow still verifies runtime archives under dist and stages, signs, and packages binaries and libraries from dist. The Unix cross-build checks also read dist; only Windows cross-staging has switched to prod. On a fresh checkout, the runtime verification or staging step cannot find the new artifacts, so the release fails. Update those consumers and the glibc/musl copy paths together. Cargo gives a custom profile its own output directory. (doc.rust-lang.org)
