Observe-before-fix instrumentation for bench bring-up: adds timestamped DIAG logging to the AD9523 clock config, ADF4382A LO manager, power sequencing, lock monitoring, temperature monitoring, and safe-mode entry. Annotates known bugs (double ad9523_setup call, timed-sync init ordering, TriggerTimedSync no-op, phase-shift before init-check, last_check timer collision) without changing any runtime behavior.
