pub fn kill_point(name: &str)Expand description
A test kill point: with AGENTD_TEST_KILL_AT=<name> set (debug /
internal-mocks builds only), the process SIGKILLs itself here — the chaos
suite’s way of dying at an exact instant between two durable writes. It
compiles to nothing in a release build without internal-mocks, so a
production binary carries no self-kill path.
