start: renumber node ranks within the launch set — a subset launch (dgx3+dgx4 = global ranks 2/3 from 4nodes-switch) sent --node-rank 2 with --nnodes 2 and vLLM rejects it ('must be between 0 and 1'); dist flags/head selection/headless-ness now use the serve-local index; container names/labels follow the launch set (_0/_1)

fix start.rs bail! string quoting (nested double quotes broke the macro — 9770012 shipped broken); same guard

serve: refuse multi-node recipes without distributed_backend — a recipe with required_nodes>1 but no distributed_backend launched N INDEPENDENT single-node engines (no --nnodes/--node-rank/--master-addr/--tensor-parallel-size), each trying to load the FULL checkpoint into one 121 GiB Spark: the actual root cause of the four glm53-flash-fp4-local-2x stalls (b12x routing OOM was the symptom). Guard bails loudly at serve time; the recipe fix (distributed_backend = "mp") restores the dist flags.

audit: GLM 2x lane RESOLVED via the card's manual flow — routing passed 42/42 (launcher died at 7/42), bench 92/100 ★★★★★; launcher-integration delta bisect is the remaining work item

audit: GLM 2x stall #4 — checkpoint on node-local NVMe (mirror content-verified) still freezes the head during b12x shard routing; NFS-page-cache hypothesis dead, routing-phase UMA exhaustion intrinsic on 2x121GB; mirror completeness fix shipped (59291f3)

mirror: verify copied repo completeness by content (entry count + du -sb vs source), not just refs/main presence — a failed cp -a (GLM: 41/42 shards after the copy died) left a partial mirror that the old refs/main gate would trust and serve; now the gate re-verifies and re-copies the partial dir, and a post-copy mismatch fails loudly (MIRROR_VERIFY_FAILED) instead of silently serving a broken tree

bench: add --node <name> — pin the bench target within a cluster (default: rank 0). A serve launched with 'serve --node' lives on a non-rank-0 node (solo Bolt on dgx3 inside 4nodes-switch), and benching the rank-0 head measured a different engine (the live kindling on dgx1 — model_not_available). pick_head tolerates the .lan suffix; web API passes node: None.

audit: DeepSeek-V4.1-Flash-1017 vs Aiden SGLang 1.7.1 image — protocol encoder is jinja-free (tool-parser-keyed), DSML markers byte-identical; one real regression (REASONING_EFFORT_MAPPINGS shifted a tier: image 25/50/75/100 vs 1017 50/75/100); TC-89 verdict contradicts its own milestones (grader flake), TC-92 recurring DS4.1 disclosure gap; GLM 2x stall root-cause refined (card requires node-local checkpoint; mirror copy incomplete 41/42 + launcher partial-mirror check hole)

bench: add --no-think and --timeout passthrough to tool-eval-bench — unblocks valid quality benches for thinking-by-default models (Ling, GLM-4.5-style) whose default reasoning blows the 120s/turn timeout and excludes most scenarios (the 10-16 fp8 Ling run scored 67/100 at 3.1% completion for exactly this reason)

upstream-watch 10-17: eugr/spark-vllm-b12x nightly (vLLM 0.1.dev21830, 10-15, 391 archs) checked — NO MuseSpark, NO Step5 (only MuseGlimmer + Step3 family). Confirms SGLang #44530 series is earliest path for Muse-816B. Bonus: b12x has DSpark speculators (Glm53DSpark, Qwen3OmniDSpark, K3DSpark, Gemma4DSpark)

upstream-watch 10-17: SGLang check — v0.5.21 has no MuseSpark/Step5 either; but MuseSpark landing via PR #44530 5-layer series (#44664 Docker + #44665 kernels merged, model layer in-flight) + merged cookbook; SGLang likely runs Muse-816B before vLLM. SGLang has bailing_moe_v3 (Ling) as an alt engine option
