[NVBUG-6448152][test] TEST ONLY; DO NOT REVIEW: benchmark combined Python asynchronous agreement

[chienchunhung]

Purpose

TEST ONLY treatment for the generation-first Python-transceiver consensus performance experiment. The branch is exactly one signed YAML-only child of corrected harness base da6e140bda4c831bc813b3b192d7cb98a37025b2. That base is one harness-only child of the official asynchronous Python transceiver draft at product head 0f9acdd4dddbde7ccbf31973ce420bf4da6cb28a: it only passes the allowlisted server_config_extra.schedule_style value into the generated runtime config and adds focused tests. It does not change product behavior.

The previous run is not generation-first evidence: although its YAML requested generation_first, the old harness omitted that key from the generated server config and the runtime used context_first. This corrected head requires both the generated config and runtime log to confirm generation_first.

Experiment

Setting	Value
Schedule	generation_first
Async terminal agreement	on
Async readiness agreement	on
Context transceiver	Python
Generation transceiver	Python
Transport	NIXL

Both agreement flags are enabled only on the four CTX PP ranks. The GEN workers use the Python transceiver but receive no CTX-only agreement flags, preserving the qualified TP1/CP1/non-ADP/PP-greater-than-one participant domain.

The run must use the exact GB300 disaggregated perf-sanity selector, verify both agreement protocols and the exact PP activation schedule, complete every submitted request, and publish an official output-token-throughput metric. Any failed request censors the throughput result.

This diagnostic is not intended to merge.
