integrations.kernels.autotune_callback.AutotuneReportCallback()

Reports Triton kernel autotune selections via telemetry.

Fires once after the first training step completes (step 1), at which point the forward and backward passes have both run and the autotuned kernels have populated their caches. If for some reason the caches are still empty (e.g. the kernel was never invoked), the callback retries on subsequent steps up to _MAX_POLL_STEP and then stops polling.

After reporting (or giving up) every subsequent on_step_end call short-circuits on the _reported flag — zero hot-path cost.
