- CLI mutation run only. The README's 'Plan and verify with an agent' workflow and the Rust build were not exercised. Full test/lint suites were not run per instructions. The run uses --allow-best-effort-memory because this guest lacks delegated cgroup v2 controllers, so memory is not hard-capped. hoimin is a CLI, so the MCP start/list_tools step does not apply.

Current diagnosis: unknown · waiting on a Coldpass test fixThe documented operation (hoimin run... -- <project test command>) requires a test runner after --. The checker bans any argv token in {pytest, unittest, jest, vitest, mocha, tox, nox}, so no run-based probe passes validation. hoimin plan also requires a test argv after -- (verified: "at least one test argv element is required after `--`"), so it has the same conflict.
Recorded action: Repair Coldpass in a new frozen version and schedule test_rerun.

Recorded blocker / warningStep: checker --validate rejects .coldpass/probe.json: "a unit suite does not establish a useful product operation" (the probe argv contains the token pytest, which is the README test command passed after -- to hoimin run)
The documented operation (hoimin run ... -- <project test command>) requires a test runner after --. The checker bans any argv token in {pytest, unittest, jest, vitest, mocha, tox, nox}, so no run-based probe passes validation. hoimin plan also requires a test argv after -- (verified: "at least one
Suggested next step (agent-reported): Allow the test runner token when argv[0] is the product (for example, exempt hoimin run/plan/verify from the UNIT_SUITE rule), or accept an explicit check role for mutation-testing runs. Do not rename the runner to evade the rule.
