- Line 10: Replace the repository-origin check in the backend selection at
.github/actions/mbx/action.yml:10 with one explicit trusted actor/event
allow-list, so only approved trusted events use the server backend and
namespace-profile-endev-linux-amd64; route every other pull request to the
GitHub backend and GitHub-hosted runner. Apply the same allow-list and routing
policy to the runner selection at .github/workflows/test.yml:19.

In @.github/actions/mbx/action.yml:
- Line 10: Define one explicit approved actor/event trust predicate and reuse it
in both sites: .github/actions/mbx/action.yml#L10-L10 must select server only
when that predicate passes, while .github/workflows/test.yml#L19-L19 must select

pull request to the GitHub backend and GitHub-hosted runner.

Note
Medium Risk
Touches all CI compilation and cache behavior plus fork/trust boundaries for OIDC and remote cache writes; application code is unchanged but a bad trust split could affect cache safety or PR CI reliability.
Overview
Replaces
Swatinem/rust-cachewith mbx (pinned 0.4.0) for compilation-heavy work inmisetasks (build,test,lint:clippy) and in CI, using mbx’s directmbx build/mbx test/mbx clippysyntax.CI is split into trusted vs untrusted paths via a new reusable
test-impl.yml. Maintainer/trusted runs use OIDC, the remotecache.mise.jdx.devbackend, and Namespacenamespace-profile-endev-linux-amd64for Linux jobs; fork and other untrusted runs use the GitHub cache backend only, with an explicit step asserting OIDC env vars are absent. The top-leveltestworkflow’sfinaljob now passes when exactly one of those paths succeeds.A composite
.github/actions/mbxaction centralizes mbx setup and backend selection. The standalonembx-dogfoodexperiment workflow is removed. AGENTS.md and CONTRIBUTING.md document Cargo equivalents and how to report mbx issues.Reviewed by Cursor Bugbot for commit 2fab6d4. Bugbot is set up for automated code reviews on this repo.
