# r28 4x DCP4 cell (2026-09-08) — clone of the r27 4x-dcp4 recipe (160/176
# RoCEnante, 46.8 t/s) retargeted at the FULL r28 source lock (cut 2026-09-06
# ~18:30 UTC across all three forks): vLLM 62f6385c (prefill/decode
# compute-time sharing + interleaved parallel prefills, chat-template
# rendering parity, GLM boundary restore, partial prefix-cache hits),
# b12x 7216f6b9 (21 commits over r27: GLM/DeepSeek loader fixes, W4A4 FC1
# fusion, M8 route prep, M1 FC2 overlap, GDN/MHC perf), LMCache 934c287a
# (3 MP-transfer robustness fixes). Same model/flags/KV pin; the image is
# the r27 build dir with the named version profile profiles/glm53-r28.env
# (clone-at-pin fetches each commit directly, the tree gates verify them).

# GLM-5.3-Flash NVFP4 — local-inference-lab quant (vLLM) — 2× DGX Spark, TP=2.
#
# local-inference-lab mixed quant: NVFP4 routed experts (layers 3–44,
# group-16) + MXFP8 MTP experts (layer 45) + W4A4 input scales. Best agent
# quant so far: tool-eval-bench 89/100 (vs 85 LibertAIDAI, 90 official FP8).
# Model: https://huggingface.co/local-inference-lab/GLM-5.3-Flash-NVFP4
#        (~186 GB → 92.72 GiB weights/node; KV pinned at 10 GiB, see below)
#
# Image: glm53-flash-nvfp4-lab:local (docker-images/glm53-flash-nvfp4-lab/ —
# day-0 arm64 image + NoPE-MLA mod + the four FujitsuPolycom lab-checkpoint
# patches: model naming shim, modelopt MTP namespace fix, persistent_topk
# CC-12.x guards). Their launch config is mirrored below.
# PROVENANCE: https://github.com/FujitsuPolycom/glm53-flash-tp2-spark
#             (Apache-2.0; see patches/UPSTREAM.md) + forum 381350 #41.
#
# Deviations from their launch script (intentional):
#   * no --kda-prefill-backend flashkda (needs their base-image patch — skipped)
#   * --kv-cache-dtype fp8_ds_mla instead of `fp8` (same packed layout; this
#     spelling is what the NoPE-MLA mod booted with on the LibertAIDAI stack)
#   * --language-model-only + no mm-renderer patch/env (text-only)
#   * no bundled NCCL/LD_PRELOAD, no NCCL_* fabric block (our switched fabric
#     is configured via [nccl.ds4] + launcher GID auto-detect)
#   * no --moe-backend marlin: their proven stack uses the default backend for
#     THIS quant and reports clean evals. Sanity-check output for token loops
#     anyway (the silent FP4 MoE corruption gotcha) before trusting a new node.
#   * flashinfer autotune disabled via --kernel-config (their proven boot);
#     VLLM_ENGINE_READY_TIMEOUT_S stays high regardless.
#
# Boot success markers (engine log, in order):
#   "Model loading took 92.72 GiB" → "[quantprobe] ... algo=MXFP8" (MTP fix
#   active; algo=None means broken) → "GPU KV cache size: 1,164,369 tokens" →
#   "Application startup complete". ~700 s sequential weight load.
#
# Test request: chat completions need "chat_template_kwargs":{"reasoning_effort"
# :"low"} — omitted/other values select MAX reasoning effort (empty content on
# short max_tokens).
#
# Optional: instanttensor loader (~30 s weight load vs ~700 s):
#   FROM glm53-flash-nvfp4-lab:local + pip install --no-deps --no-build-isolation
#   instanttensor==0.1.9, then add --load-format instanttensor (--no-deps is
#   required: resolution would downgrade the image's NCCL).
#
# PREREQUISITES: weights cached on both nodes:
# [A/B CELL 2026-09-03] ship recipe verbatim, checkpoint swapped to the lab
# non-Spark NVFP4 (isolates checkpoint from image lineage vs the lab-image cell).
# [BISECT A2 2026-09-03] EXACT 90/100 recipe (236ce5a) + instanttensor + JIT
# mounts, on the CURRENT eugr-patched image. Isolates image lineage from the
# execution-env/flag cluster (AOT/V2/b12x/card-env). Comparator: 124/138.

# local-inference-lab/GLM-5.3-Flash-NVFP4-Spark (rev 06972cdee7280cec849aedf05a02062b3e870246):

# separate model-mtp-0000x.safetensors shards (mtp_tokens: 5 per their
# lil.yaml), amax/nonexpert/inputscales side shards, Glm5NextForConditionalGeneration.
# THE "DSpark speculative embedded" checkpoint — no separate DFlash2 download
# needed; lil.yaml: default_speculator mtp, dflash2_tokens 7 (r12 doc fr: their
# standalone-Q: MTP:3 254 tok/s CC1, 333 Sieve, 94 steps/s).
#
# Image: glm53-flash-nvfp4-lab:local (same proven day-0 arm64 stack + NoPE-MLA
# mod + modelopt MTP namespace patch used by the 92/100 lab lane). The MTP
# layer here is NVFP4 (not MXFP8) — the quantprobe marker may print
# algo=NVFP4/- different; algo=None = patch missed (fall back to 4p67 image).
#
# Deviations from lab (unchanged mechanics): same fabric/env/GMU/KV pinning.
# lil.yaml launch mirrors: block 256, disable_flashinfer_autotune, mm data
