Four systematic passes covering Rust kernel invariants (4 criticals — missing EXIT_RESIDUAL action, unwrap() panic on NUL, backward FSM transition, stale all_legs_done variable), config validation chain (zero validators on 127 fields), persistence schema drift (7 confirmed field-level mismatches), and lifecycle management (no signal handlers, no __del__, no exception safety in builder).
