## What changed
Export `run_integrity_checks` from `exec-server` to check whether the effective filesystem policy permits writing containment dependencies on Linux, macOS, and Windows. Run preparation and checks on a blocking worker, limit waiting to five seconds, and keep results observational without affecting execution.
Skip mismatched sandbox backends, full-disk-write policies, and `EscalatedSandboxWithRestrictions` overrides. Continue checking ordinary configured policies with root write access and deny restrictions.
Record check outcomes, preparation time, and total duration with bounded metric tags that omit filesystem paths.
## Testing
Add coverage for findings, clean results, missing dependencies, preparation errors, eligibility rules, and timeouts. Verify that timed-out workers emit no late results and that metrics contain no filesystem paths.
