Module runner 

ev check –run: execute a bound test locally and produce a run-receipt. A THIN runner — the production receipt-writer is CI / a supervisor hook; –run is for local verification. exit == the configured green_exit_code => green, anything else => red (gray comes from external writers, never from –run).

Functions

run_check

Run the bound reference as a shell command in repo; return a receipt stamped for platform, the current git commit (HEAD), and now (UTC). exit == green_exit_code => green, else red.
