- Enable ML Diagnostics profiler on secondary TPU worker processes by removing the jax.process_index() == 0 lock from _ml_diagnostics_profiler_enabled().
- Refactor Profiler class in max_utils.py with active state tracking (_active). When both enable_ml_diagnostics and enable_profiler are True, prioritize ML Diagnostics and skip the standalone JAX profiler with a log warning to avoid RuntimeError tracer collisions.
