# MI355X Kimi-K2.6 (FP8) 2-node 1P1D disaggregation recipe (base + EAGLE3 MTP).
#
# Self-contained (no inheritance): same as 1p1d.yaml plus the `mtp:` block. Uses
# EAGLE3 speculative decoding with an EXTERNAL draft checkpoint (unlike DSV4's
# built-in EAGLE NextN head): the launcher resolves mtp.draft_model_path through
# the HF-cache snapshot logic and appends --speculative-draft-model-path. The
# draft dir must live under /it-share (the container's :ro mount). MTP is applied
# to both prefill and decode. Mirrors the Kimi-K2.6 serving cookbook.
#
# Consumed by:
# * scripts/ci/slurm/process_result.py reads `resources` and
# `backend.sglang_config` (TP/EP/DP + worker counts) for the summary table.
# * scripts/ci/slurm/launch_mi355x.sh reads `runtime`, `bench`, `model`, `mtp`.
