1. 1. Summary

• Give local/non-RBE Bazel executions a 7200-second fallback timeout per retry attempt.
• Preserve explicit timeouts and the existing 3600-second remote execution fallback.
• Add coverage for local, remote, and explicit timeout selection.

1. 1. Motivation

A hung local Bazel invocation could reach the outer Evergreen execution timeout before retry_bazel_cmd saw a timeout exit and started another attempt. The local fallback lets the existing retry loop recover.

1. 1. Safety

Explicit build_timeout_seconds remains authoritative. Remote execution behavior is unchanged.

1. 1. Testing

• bazel test //evergreen:bazel_evergreen_shutils_test
• bash -n evergreen/bazel_evergreen_shutils.sh
• bash -n evergreen/bazel_evergreen_shutils_test.sh
• git diff --check
