A TERM-only timeout relies on the child exiting. Keep a fixed five-second KILL backstop, preserve every timeout as a failure and bind the shell/Go command proofs to the actual bounded invocation. Contract-Neutral: Internal build timeout containment; source graph, endpoints, checksum trust and artifact acceptance are unchanged. Change-source: pulse-maintainer
