vllm-probe:0.24.0-fixandtrtllm-probe:1.3.0rc20-onnxfixare local tags. A reader cannot rebuild them from this repository, so a probe result cannot be traced back to a reproducible runtime. Thesglangentries point to public images and are fine.Add the base image and the applied patches for each local tag, either inline here or in a

Inline comments:
In `@collector/facts/gen_archive.py`:
- Line 220: Replace the hardcoded platform value in the provenance record with
the device name and compute capability collected by the probe, ensuring those
fields are emitted in probe JSON and copied into provenance. Update
render_sglang_cli and render_vllm_run_sh so system_name is supplied through a
CLI argument and used consistently for rendering and recorded metadata,
preventing divergence between the rendered system and archive facts.
- Around line 171-188: In collector/facts/gen_archive.py lines 171-188, use one
shared container probe-directory constant for all generated probe commands and
mount collector/facts there in the Docker command construction so the scripts
are available without manual copying; also update the module docstring at lines
7-9 to reference the current location. In collector/facts/README.md lines 47-58,
document the new mount/setup expected by the generated commands.
- Around line 67-72: Update the no-variants branch in the family expansion loop
to append a skip/drop entry for the affected family, including a clear reason
that it has no dummy variants, before continuing. Match the existing skip-entry
structure used for missing dummy directories so every declared family that
expands to zero runs is represented in the plan.
In `@collector/facts/gen_dummy_models.py`:
- Around line 139-161: Update the variant-generation adapter around pick and its
caller main to return drop reasons alongside generated variants, recording why
each declared variant—csa, hca, full, interleave_pair, rep_mix, or hash—was
omitted; ensure main logs those reasons so zero-case expansions are explained.
In the hash variant path, remove the pick("csa", 1) or [0] fallback and raise an
error when no CSA layer is available, preserving the existing layer geometry
contract.
- Around line 290-318: Move the stale-reference validation and failure handling
in the variant-generation flow before creating the variant directory or writing
config.json. Update the logic around _check_no_stale_layer_refs so stale
variants are reported and counted without leaving an output directory; remove
the later duplicate stale check while preserving manifest and output behavior
for valid variants.
In `@collector/facts/make_records.py`:
- Around line 62-79: Update the merge key and aggregation in the spans loop so
distinct span names/API operations remain separate even when their normalized
kernel sets match. Preserve each merged slot’s op and API identity, and
accumulate calls across spans only when they represent the same span name; avoid
overwriting earlier operation metadata through setdefault or last-write
behavior.
- Around line 115-116: Update the records-generation flow so runs without raw
JSON emit a missing record instead of being skipped, matching
gen_archive.collect. Replace first-error extraction from f["errors"] with
preservation of every error stage, and include the true orphan-kernel count when
the displayed list is capped at 15.
In `@collector/facts/probe_sglang.py`:
- Line 167: Update the trace-stage guard around args.trace so it also verifies
that stage 2 actually ran successfully before referencing model_runner, model,
or ret. Preserve tracing after non-stage-2 errors only when those stage-2
variables were initialized, and ensure skipped stage 2 is recorded with an
explicit trace_skipped reason rather than misclassified as an attn_hook,
quant_hook, or trace failure.
In `@collector/facts/probe_trtllm.py`:
- Around line 54-70: Update the _safe_walk shim to append each swallowed
exception, including the module context when available, to a module-level
_WALK_TRUNCATIONS list before terminating iteration. Record this list as
rec["walk_package_truncations"] alongside rec["cutlass_stub_modules"] before the
record is written, and have _CutlassWalkGuard.find_spec add equivalent
truncation evidence when its guarded walk encounters an exception.
In `@collector/facts/probe_vllm.py`:
- Around line 104-116: Wrap the setup block containing parse_run_sh, model
override handling, and vllm import in try/except so failures are recorded with
traceback under a setup stage key, written to rec, and returned through the
existing output path instead of crashing. Update the --model override logic to
handle both separate --model path tokens and the --model=path form while
preserving current behavior.

Minor comments:
In `@collector/facts/gen_archive.py`:
- Around line 141-148: Update the git metadata commands in the archive
generation flow to detect non-zero git exit statuses, such as by enabling
subprocess failure checking, so failed repository lookups enter the existing
fallback path and set both values to "unknown"; preserve the current
detached-branch behavior only when git succeeds but reports no branch.
- Around line 216-223: Update the run-summary counters around status
classification to count ok_degraded separately and include that count in the
final print so all planned runs are represented. Also tighten the soft-error
guard involving the attn_hook stage so a skipped stage 2 or missing model is not
classified as ok_degraded; such runs must remain error or missing according to
the existing status rules.
In `@collector/facts/gen_dummy_models.py`:
- Around line 176-179: Fix the Ruff violations by combining the nested
conditions guarding the num_hash_layers update into one condition, and update
the zip over indexer_types and mlp_layer_types to enforce equal lengths with
strict pairing so variant selection cannot silently truncate.
In `@collector/facts/probe_sglang.py`:
- Around line 42-47: Fix Ruff violations in the argument definitions by wrapping
the long help strings for --quantization, --kv-dtype, and --run-forward without
changing their behavior. Update the code at the B009 location around the
affected argument access to avoid a prohibited getattr-style call, and sort the
import block using Ruff’s I001 ordering.
In `@collector/facts/probe_trtllm.py`:
- Line 182: Update the output write in the probe’s main flow to use a
context-managed file handle so it is closed reliably, and reorder the imports in
the module-level and local import blocks to satisfy Ruff I001. Preserve the
existing JSON output, indentation, and default serialization behavior.
In `@collector/facts/probe_vllm.py`:
- Line 35: Replace each direct open call in the probe module with a context
manager, including the record writes before gen_archive.collect, so files are
closed before their contents are consumed. Also reformat the overlong statement
associated with the E501 violation while preserving its behavior.

collector/**: - Enforce the collector rules from.claude/rules/collector/layer_permissions.md,failure_handling.md, andcase_authoring.md.
- Flag any silent case skip in collector code (a queued case may only execute or raise); the sole sanctioned filter is generation-time memory feasibility with counted drops.
- Flag invented fallbacks on both ends: generation must raise on unresolvable declarations (never substitute defaults or another model's geometry); collectors must never swap in a different backend/kernel than the framework's own dispatch selects — manual pins require framework source citations.
- Flag any reintroduction of selector/exception machinery (case_ids/contains/indices/ranges/limit/rules, sm_exceptions-style shape or version predicates) in YAML or code.
- Capability floors (
cases/capabilities.yaml) may hold hardware facts only: no shapes, no framework versions, no per-backend nesting.cases/denylist.yamlis for hang/node-killers only, dated.- Collector changes must stay within
collector/andtests/unit/collector/; flag producer+consumer contract changes (perf row schema, PerfFile names) unless the PR explicitly declares them.- Check collector changes for backend/runtime version accuracy, GPU resource assumptions, reproducible command construction, and clear failure evidence.
- Flag changes that make support-matrix or perf-data results harder to trace back to the command, model, system, quantization, or runtime version that produced them.

Learning: In collector-related Python files (e.g., collector/trtllm/collect_moe_v3.py), document and enforce that version incompatibilities are surfaced as non-fatal runtime errors during collection. Do not add aggressive preventive version-gating; instead, allow generating test cases that may not be supported across all versions within the __compat__ range and rely on runtime error handling to skip or flag unsupported cases. This should be verifiable by ensuring collection proceeds, errors are reported, and unsupported cases do not halt the overall process.

Learning: For DeepSeek-V4 CSA top-k DELTA calibration in ai-dynamo/aiconfigurator, apply calibration data only when the runtime native num_heads exactly matches the calibration bucket (currently 64 or 128). Do not borrow calibration across head-count buckets: Flash and Pro DELTA values can diverge by up to 37% at long-context shapes. This exact-match rule applies to both Python and Rust consumers, including collector/case_generator.py.

Do not hardcode the platform label, and reconcile it with the rendered system.
Line 220 stamps "platform": "h20_sm90" on every collected run. Two problems follow:
- The label is not measured. If the queue runs on a different GPU, every record in
archive.jsonlis mislabeled, and a reader cannot trace the facts back to the system that produced them. - The label contradicts the rendering input.
render_sglang_cli(line 48) andrender_vllm_run_sh(line 116) both pass"system_name": "h200_sxm". The engine args are rendered for H200 while the record claims H20.
Read the device name and compute capability inside the probe, put them in the probe JSON, and copy them into the provenance here. Make the rendered system_name a CLI argument so the two values cannot diverge. The change spans the probes and this file, so a one-click suggestion is not safe.
As per path instructions: "Flag changes that make support-matrix or perf-data results harder to trace back to the command, model, system, quantization, or runtime version that produced them."

Do not drop declared variants silently, and do not substitute layer 0 as a default.
targets.yaml declares dummy_variants: [csa, hca, full, interleave_pair, dspark, hash, rep_mix] for dsv4. This function drops any of those variants without a record when the source config does not supply the required layer kind:
- Line 145:
if sel:dropscsa,hca, orfull. - Line 149 and line 155: drop
interleave_pairandrep_mix. - Line 159: drops
hashwhenlen(tail) != n_hash, which the comment at lines 132-133 says happens for the NVIDIA NVFP4 requants.
gen_archive.py later reports no dummy dir <name> for each missing variant, so the reason for the drop is never recorded. A declared variant that expands to zero cases needs an explanation at the point of the drop.
Line 160 is a separate problem: pick("csa", 1) or [0] substitutes layer 0 when the checkpoint has no CSA layer. That is an invented fallback and it produces a hash variant with the wrong layer geometry.
Return the drop reasons alongside the variants and log them in main, and raise instead of falling back to [0]. The change touches the adapter return contract and main, so a one-click suggestion is not safe.
As per coding guidelines: "When a declared model row, quant mode, attention/MLA profile, or artifact configuration cannot be resolved, raise an error; never substitute defaults, another model's geometry, or a close-enough quant mode" and "A planned operation expanding to zero cases must have logged capability-floor or memory-filter drops; zero cases without an explanation are population bugs."

reasons so zero-case expansions are explained. In the hash variant path, remove

available, preserving the existing layer geometry contract.

The curated layer loses failure evidence.
Two places drop information that the archive keeps:
- Line 115-116: a run with no raw JSON is skipped entirely.
gen_archive.collectwrites a"status": "missing"line for the same run, soarchive.jsonlandrecords.jsonldisagree on the population. - Line 146-147:
next(iter(f["errors"].items()))reports only the first recorded error.probe_sglang.pycan record several entries at once, for examplemoe_hookandtrace. The remaining stages vanish from the record, and dictionary insertion order decides which one survives.
Emit a missing record for the first case, and carry every error stage for the second.
🐛 Proposed fix for the outcome field
"outcome": ({"status": "ok"} if not f.get("errors") else
- compress_error(*next(iter(f["errors"].items())))),
+ {"status": "error",
+ "stages": [compress_error(k, v) for k, v in f["errors"].items()]}),Line 96 also truncates the orphan kernels to 15 without recording the true count. Add the count so a reader can tell that the coverage signal was cut.
As per path instructions: "Check collector changes for ... clear failure evidence."

Record when the walk_packages shim swallows an exception.
_safe_walk replaces pkgutil.walk_packages for the whole process and returns on any exception. The record keeps no evidence that a truncation happened, and no evidence of which module raised. rec["cutlass_stub_modules"] documents the stub at line 130, but the walk patch and _CutlassWalkGuard leave no trace.
A silent truncation changes the cutlass JIT cache key and can change which kernels the probe observes. That makes the recorded kernel facts hard to trust.
Collect the swallowed exceptions in a module-level list and write it into rec next to cutlass_stub_modules.

Record the early-stage failures instead of crashing before the record is written.
Lines 104 to 116 run outside any try. Three failures are reachable here and none of them writes args.out:
parse_run_shraisesValueErrorwhen therun.shhas noengine_command=(...)block (line 38).- Line 109 raises
ValueErrorwhen--modelis absent fromargv. This happens when the generator renders--model=<path>as a single token, or when the launcher prefix strip at lines 41-42 removes a positional model argument. import vllmat line 114 raises when the image is wrong.
gen_archive.collect then classifies the run as missing with no reason, so the cause of the failure is lost. Every probe failure must become a structured, classified fact.
Wrap lines 104 to 116 in a try, record the traceback under a stage key such as setup, write rec, and return. Also accept the --model=<path> form when applying --model-override. The change spans several statements and a helper for the record write, so a one-click suggestion is not safe.
As per path instructions, from .claude/rules/collector/failure_handling.md: "Probe crashes, load failures, rejected configurations, and ordinary OOMs must be emitted as structured, classified failure facts rather than skipped."

Learning: In collector-related Python files (e.g., collector/trtllm/collect_moe_v3.py), document and enforce that version incompatibilities are surfaced as non-fatal runtime errors during collection. Do not add aggressive preventive version-gating; instead, allow generating test cases that may not be supported across all versions within the __compat__ range and rely on runtime error handling to skip or flag unsupported cases. This should be verifiable by ensuring collection proceeds, errors are reported, and unsupported cases do not halt the overall process.

Do not report failed probes as unprobed.
make_records.py writes records with an error outcome.status, but this branch removes them before matching. A fact row with only failed matching probes is then reported as unprobed, although a probe record exists and contains failure evidence.
Keep failed records in a separate index and report them distinctly from absent probes. A one-click change is not safe because this requires an explicit verdict and output contract for probe failures.
As per path instructions: “Flag changes that make support-matrix or perf-data results harder to trace back to the command, model, system, quantization, or runtime version that produced them.”

collector/**: - Enforce the collector rules from.claude/rules/collector/layer_permissions.md,failure_handling.md, andcase_authoring.md.
- Flag any silent case skip in collector code (a queued case may only execute or raise); the sole sanctioned filter is generation-time memory feasibility with counted drops.
- Flag invented fallbacks on both ends: generation must raise on unresolvable declarations (never substitute defaults or another model's geometry); collectors must never swap in a different backend/kernel than the framework's own dispatch selects — manual pins require framework source citations.
- Flag any reintroduction of selector/exception machinery (case_ids/contains/indices/ranges/limit/rules, sm_exceptions-style shape or version predicates) in YAML or code.
- Capability floors (
cases/capabilities.yaml) may hold hardware facts only: no shapes, no framework versions, no per-backend nesting.cases/denylist.yamlis for hang/node-killers only, dated.- Collector changes must stay within
collector/andtests/unit/collector/; flag producer+consumer contract changes (perf row schema, PerfFile names) unless the PR explicitly declares them.- Check collector changes for backend/runtime version accuracy, GPU resource assumptions, reproducible command construction, and clear failure evidence.
- Flag changes that make support-matrix or perf-data results harder to trace back to the command, model, system, quantization, or runtime version that produced them.

Learning: In collector-related Python files (e.g., collector/trtllm/collect_moe_v3.py), document and enforce that version incompatibilities are surfaced as non-fatal runtime errors during collection. Do not add aggressive preventive version-gating; instead, allow generating test cases that may not be supported across all versions within the __compat__ range and rely on runtime error handling to skip or flag unsupported cases. This should be verifiable by ensuring collection proceeds, errors are reported, and unsupported cases do not halt the overall process.

The new module fails the repository copyright check. Add the project-standard header at the file start. A one-click change is not safe because the canonical header is not included here.

collector/**: - Enforce the collector rules from.claude/rules/collector/layer_permissions.md,failure_handling.md, andcase_authoring.md.
- Flag any silent case skip in collector code (a queued case may only execute or raise); the sole sanctioned filter is generation-time memory feasibility with counted drops.
- Flag invented fallbacks on both ends: generation must raise on unresolvable declarations (never substitute defaults or another model's geometry); collectors must never swap in a different backend/kernel than the framework's own dispatch selects — manual pins require framework source citations.
- Flag any reintroduction of selector/exception machinery (case_ids/contains/indices/ranges/limit/rules, sm_exceptions-style shape or version predicates) in YAML or code.
- Capability floors (
cases/capabilities.yaml) may hold hardware facts only: no shapes, no framework versions, no per-backend nesting.cases/denylist.yamlis for hang/node-killers only, dated.- Collector changes must stay within
collector/andtests/unit/collector/; flag producer+consumer contract changes (perf row schema, PerfFile names) unless the PR explicitly declares them.- Check collector changes for backend/runtime version accuracy, GPU resource assumptions, reproducible command construction, and clear failure evidence.
- Flag changes that make support-matrix or perf-data results harder to trace back to the command, model, system, quantization, or runtime version that produced them.

…orrectness Probe-first facts for op upgrades: dummy-weight models (depth-cut, width-true), generator-rendered engine args as probe input, and three-level identity capture (per-module quant methods / API boundaries with Python call chains / CUDA kernels per span) across sglang, vLLM and TRT-LLM. Rejections and crashes are recorded as structured facts. Includes the target matrix seeded from model_configs + AIC kv pairing, per-GPU queue driver with incremental reruns and provenance, and a curated-records layer. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
probe_runner/fpm_adapter/trtllm_probe named three different things (role, input format, backend); the layer they share is per-backend, so name by it. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
… concern Lives with what it validates, reuses the collector's model definitions, and inherits collector governance. 'facts' matches the repo's existing vocabulary (op_backend_facts.yaml, evidence_policy). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…ackend_facts.yaml Per-row verdicts: confirmed / contradicted / needs-taxonomy / unprobed. Deliberately conservative: 'confirmed' needs clear kernel/api evidence; vague hand-written labels (torch_flow, default) land in needs-taxonomy, which doubles as the work list for the kernel-name taxonomy table. First run on SM90: 435 adjudicable rows -> 74 confirmed, 136 needs-taxonomy, 225 unprobed, 0 contradicted. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Pairs with check_facts.py (generate facts / check facts). The archive/ directory name stays: it is the evidence store; only the script was misnamed after it. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…nk-injection probe - topologies: drop the speculative tp2/4/8 rows; record the probed TEP-vs-EP verdict (triton MoE family: same main kernel, activation-variant and shape differences only) and the per-runner-family audit policy (marlin, flashinfer_trtllm pending). - gen_facts: derive is_moe from the variant's config instead of hardcoding True (dense targets would have gotten MoE-branch parallelism args); nextn=0 is now documented as the dummy generator's recorded decision. - inject/sitecustomize.py: rank-side probe injection for multi-rank runs (validated on tp2: per-rank identity + per-call MoE/attention kernel capture; how the TEP/EP verdict was produced).

…nsion
Earlier policy ('audit once per MoE runner family, then drop dual-topology
sweeps') generalized from GLM/DSV4, which happen not to fork. Kimi-K3 TEP8 is
known to select different kernels — so record topology always; agreement is
itself a fact a version bump can invalidate. Per-SM matrix: sm90/100/103 get
tp1, TEP8 and DEP8; sm89/120 single-GPU only.

…delity rules Targets grow from 12 to 30 checkpoints: every special-attention architecture in the collector support matrix (MLA/DSA, SWA, mamba/GDN, sparse) in the identities that exist upstream (default / fp8 / nvfp4 / mxfp4). A generic adapter detects the interleave axis (layer_types, attn_type_list, hybrid_override_pattern, ...) so new architectures need no bespoke code. Probe now replicates scheduler.py's global init sequence (MoE runner, fp8/fp4 gemm, mamba SSU backend) — without it the probe took a different dispatch path than real serving. Adds inject/sitecustomize.py for multi-rank runs. Hopper sweep: 30 runs, 25 ok, 5 recorded-error facts (DSV4 W4A8 crashes, DSV4-NVFP4 rejected via the flashinfer_trtllm_routed override, M3-MXFP8 needs sm100). Harness-caused failures are now zero; the five dummy fidelity rules that got us there are documented in the README. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
vLLM and TRT-LLM now run the same 30-checkpoint matrix as sglang. sglang 25/30, vllm 24/28, trtllm 14/28 — remaining failures are recorded framework facts, not harness gaps. Probe/driver fixes this required: - vllm: FPM rendering silently falls back to the dynamo target when its preconditions do not hold (run_0.sh instead of run.sh); accept both and record which artifact was used. Parse the dynamo multi-line invocation without swallowing the shell plumbing after it. - trtllm: always pass trust_remote_code for dummy probing. - records: attention identity falls back from backend object (sglang) to wrapped spans (vllm) to the attention kernel family (trtllm). Notable cross-framework facts: NVFP4 GEMM on SM90 is REJECTED by trtllm (CutlassFp4GemmRunner arch unsupported) while sglang silently runs it on Marlin bf16 dequant; GLM fp8/nvfp4 KV has no valid vLLM attention backend on SM90 (head_size 576) across the whole 5.1/5.2 family.

targets.yaml no longer hand-lists roster checkpoints. The roster family is now 'derive: true': checkpoints = every repo the cases yamls mention, minus gated repos and special-family-owned repos, plus probe-only extra_repos (Kimi-K3 pair). Profile comes from derive_profile.py — the checkpoint's own quant metadata (hf_quant sidecar, modelopt MIXED_PRECISION groups AND flat quantized_layers, compressed-tensors bit/type inspection) — never the repo name. Variants come from the dummy manifest, representative-first. Derivation exposed three hand-roster errors, all corrected: - MiniMax-M3-MXFP8 is mxfp8, not fp8 (kv_pairing gains an mxfp8 row) - Kimi-K3 native weights are 4-bit float group-32, not fp8 - (earlier) Kimi-K3-NVFP4 modelopt_mixed was misread as bfloat16 Plan diff vs the hand roster: identical except the four V4 repos' default variants upgrade to their dsv4-adapter kv-structural variants; the 8 replacement runs re-document the same facts (ue8m0-on-SM90, pre-blackwell rejection). Coverage floor check is derivation-aware and passing. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…ontract) gen_facts renders extra_engine_args yaml per trtllm run (same template the deployment worker consumes, incl. kv_cache_dtype passthrough mirroring module_bridge.py:140); probe_trtllm feeds it to llmapi with two recorded probe overrides (KV pool capped at max_tokens=16384 instead of free_gpu_memory_fraction; cuda_graph_config dropped — identity probes run eager). Unknown yaml keys surface as engine_yaml_unknown_args drift facts instead of crashing. Validated: dense (Qwen3-0.6B) and MoE (DeepSeek-V3, moe_config backend CUTLASS) both accept every rendered key on rc23. engine_args_fidelity: probe-defaults -> generator-rendered. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
… not a bug The all_kinds dummy keeps one real 512-expert MoE layer (width-true rule): 64B params = 120GiB bf16 > one H20. trtllm materializes dummy weights in bf16; sglang/vllm load in checkpoint precision and fit. Probing this checkpoint on trtllm needs tp8. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Full 76-run trtllm re-sweep under generator-rendered engine args flipped 6 runs OK->ERR — every flip is a deployment-config fact the probe-default args masked: - GLM-5/5.1/5.2-FP8 and DeepSeek-V3.2: native abort when kv_cache_config.dtype=fp8 (what the generator renders for fp8 profiles); kv auto loads fine — A/B verified on GLM-5-FP8 with the same yaml - MiniMax-M2/M2.5: fp8 Linear.apply assertion under rendered args This is the argument for engine-arg fidelity: probe-defaults 'worked' and would have certified configs that crash in deployment.

…and SM-gated K3 lands in sglang v0.5.17 / vllm v0.27.1 / trtllm 1.3.0rc24 (all register KimiK3ForConditionalGeneration; unregistered at the current pins). Probed: - sglang 0.5.17 SM90: tp1 == TEP8 == DEP8(a2a none) — Mxfp4MoEMethod dequants the 4-bit-float weights to bf16 and runs triton fused_moe (no fp4 path on Hopper). DEP8+deepep (the real DEP route) crashes at warmup: 'forward_deepgemm_contiguous is deprecated'. - The owner-reported TEP8 kernel fork is SM-GATED, per sglang's own dispatch log: 'K3 SP collective requires SM103, TP4/TP8, MegaMoE/DeepEP, and CustomAllReduceV2 with multicast; using NCCL.' — inactive on SM90, verify during the Blackwell(SM103) replay. - vllm 0.27.1: OK — KimiK3DeltaAttention + Mxfp4MoEMethod. - trtllm rc24: registers K3 but the image lacks the 'fla' package the model imports — unserveable out of the box. - inject: DeepEPMoE.forward hook (deepep route bypasses FusedMoE.forward).

…ibuted Roster expansion (owner: the aic-core model_configs list): 7 HF-gated repos un-gated by sourcing configs from aic-core/model_configs (all Llama incl. Llama-4, Qwen3-32B-FP8-Static, Nemotron-Ultra-FP8) + nvidia/DeepSeek-V3.2-NVFP4. All 8 probed on all three backends; DSV3.2-NVFP4 reproduces its FP8 sibling's facts exactly (sglang DSA ok / vllm head-576 no-backend / trtllm fp8-KV crash). Dummy fidelity additions, each from a real failure: - _ARCH_IMPLICIT_PERIODS: Llama-4's layer-kind period is framework-hardcoded (sglang llama4.py:217, no config field) -> depth8 + depth4 capacity variant (Maverick's 8x128-expert layers exceed one GPU on sglang AND vllm) - vision_config merged from mirror configs (aic-core strips it; vllm builds and PROFILES the vision tower even for text-only probes: 577-vs-1025 crash) - explicit auto_map removal for gated custom code (official NVFP4 sibling ships none — native nemotron_h), recorded as an edit - hf_quant stub completion from the sibling's real file (aic-core stubs lack exclude_modules; sglang's modelopt parser requires it) sglang failure attribution now 15/15 experiment-backed: - DSV4 ue8m0: framework_bug — ALL FIVE MoE runners fail (cutlass lacks ab_strides1, triton_kernel arange assert, flashinfer_cutlass lacks .runner, + the two earlier) - MiniMax-M2/M2.5 flake: flashinfer tvm_ffi nondeterminism, deterministic workaround SGLANG_IS_FLASHINFER_AVAILABLE=false verified 4/4 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…o needs_flags for the generator
31 trtllm errs -> experiment-backed causes:
- UNIFIED fp8-KV finding: fp8 KV in the MLA/DSA path crashes flash_mla on
SM90. Two doors, A/B'd separately: engine kv dtype (config_gap — 6 runs
incl. MiniMax-M2/M2.5 whose 'Linear assert' was the same trigger, kv-auto
passes) vs checkpoint hf_quant kv_cache_quant_algo=FP8 (framework_bug —
3 NVFP4 artifacts, kv-auto still crashes)
- DSV4: generator's tokens_per_block=64 is illegal for DeepseekV4CacheManager
([128,256]) on ANY platform; behind it sits the explicit pre-blackwell
rejection (platform_floor on SM90)
- MiniMax-M3: llmapi sparse_attention_config{algorithm:minimax_m3} is a
REQUIRED flag the generator omits; deeper rc23 gap remains after it
- Kimi-K2.5: rc23 compressed-tensors quant parser crash (framework_bug)
- rest: explicit platform floors (NVFP4 tactics/SM100, pre-blackwell,
min-sm) and arch_unregistered — clean rejections, no experiments needed

sglang/SM90: the NVFP4 MoE gate allows marlin only (three alternative runners cleanly rejected), and marlin fused_moe asserts gated-SiLU-only — Gemma's gelu MoE is unservable; dense 31B-IT passes. vllm 0.24: the real artifact's hf_quant excludes lm_head but not the tied embed_tokens, and ModelOpt NVFP4 has no embedding quant method -> NotImplementedError at load for both 26B and 31B-IT (real deployments hit the same).

rc23 dies in quant parsing before the arch check (two stacked walls); rc24 clears parsing + registers the arch but the image lacks 'fla'. K3-NVFP4's FP8_PB_WO quant algo is absent from the QuantAlgo enum in both rc23 and rc24 — unservable independent of arch support. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
… fp8-WO path The artifact mixes NVFP4 experts with FP8 per-block WEIGHT-ONLY attention projections; rc23/rc24's nearest QuantAlgo member (FP8_BLOCK_SCALES) is W8A8, not weight-only. Not a rename-level gap. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

quant_method='modelopt' + quant_algo='MIXED_PRECISION' falls through both the modelopt_mixed literal match (modelopt_quant.py:622) and the FP8/FP4 substring check (base_config.py:189-196) -> Unquantized with no warning.

'auto' was echoed verbatim through every config surface; the real dtype only exists where the cache is allocated. Capture it there per backend: sglang ModelRunner/token_to_kv_pool, vllm GPUModelRunner kv_cache_spec, trtllm *CacheManager (incl. Mamba hybrids). report_matrix.py renders cfg->measured per cell and prefers ok-status records (fixes the v6 blank DSV4xsglang identity). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…red IMA Rerun with memory monitor: peak 33GB/96GB, weights fit (the 64B/120GiB arithmetic assumed gated-3-mat at hidden width, ignoring moe_latent_size 2048 + relu2; true experts/layer ~10.7B). Actual failure is an illegal memory access right after model init (cudaStreamDestroy IMA -> abort in KVCacheManager teardown, exit 139). Isolation across siblings pins it to Ultra-shape x NVFP4-path on rc23. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

targets.yaml becomes the single per-model declaration surface: special- family adapter routing derives from families.*.checkpoints (+ roster dummy_overrides.family for dsv4-arch roster checkpoints), and the two factual edit tables (hf_quant sibling completion, declared auto_map removal) become checkpoint_overrides.*.dummy_overrides with fact strings. gen_dummy_models.py loads them at import; regenerating all 181 dummy configs is byte-identical to the hardcoded-table output.

Pin the exact rendered surface each archived fact was measured under: sglang engine CLI, vllm engine_command line + template hash, trtllm agg_config.yaml. One merged YAML per backend (~200KB text total, no LFS — canonicalization is the size answer, and pointer files would kill the reviewable diff). golden_snapshots.py --check re-renders (CPU-only, golden cache keyed on generator commit) and lists STALE cells whose facts predate the current render. Scope is deliberately the probed slice: this pins facts provenance, it is NOT a generator regression suite. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Pristine vllm/vllm-openai:v0.24.0 cannot load DSV4: tilelang's libcudart_stub.so (undefined symbol cudaDeviceReset) is resolved by the engine load path via ctypes. Minimal imports do not trigger it — the A/B on the pristine image reproduces the exact crash, so real 0.24.0-image DSV4 deployments hit it too. v0.27.1 ships tilelang without stubs (upstream fixed); the -fix image is a recorded stub->real-libcudart symlink with no dispatch impact, to be dropped when the pin moves past 0.24.

…a deliverable The HTML matrix renderer is a workspace-side consumer of the facts archive (hand-curated per-cell verdict strings, publishing-oriented); the PR ships the harness and the facts, not the report generator. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
… another pipeline's job This PR generates facts (probe records + golden commands); reconciling them against collector/op_backend_facts.yaml belongs to the collector-alignment pipeline that consumes the facts. kernel_taxonomy.yaml stays: it is make_records' input for labeling captured kernels into backend families — fact curation, not comparison. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Owner scoping: multi-rank probing is limited to routes that change kernels; measured invariance (facts/tepdep) shows a2a=none ep/tp sharding keeps kernel families, so tp1 represents the default path. K3 is the one deepep- required target — A/B verdict: no working deepep mode on sglang 0.5.17 + bundled DeepEP @ SM90 (auto -> deprecated contiguous-deepgemm assert; low_latency -> internode_ll num_topk cap vs K3 topk16), and K3's own SP-collective/MegaMoE route is SM103-gated. records.runtime now carries ep/dp/a2a; the injector hooks expert-module classes found in the model instead of guessing import paths (deepep/TBO dispatchers bypassed the old entries).

Replace configs/inaccessible.json with targets.yaml roster.excluded — each exclusion carries decided_by/date/reason. A repo the collector mentions whose config is missing now hard-stops derive_roster with OWNER DECISION NEEDED; there is no self-service escape hatch. Recorded owner decisions: Llama-4-Scout base (Instruct covers kernel identity) and nemotron-ultra-rl-050826 (no public artifact). Coverage check passes: 93 mentioned / 95 covered / 2 owner-excluded.

derive_profile.py (61 lines, one consumer), make_records.py (records stage), and golden_snapshots.py (freshness) merge into gen_facts.py as subcommands (--records, --snapshot-update/--snapshot-check). The module count drops 12 -> 7; what remains separate has a hard boundary: the three probes execute inside different framework containers, sitecustomize's filename IS the injection mechanism, gen_dummy_models is a rarely-run builder, build_images.sh is shell. Behavior-preserving: --records regenerates all 335 records byte-identical (modulo the new ep/dp/a2a runtime fields), snapshots re-render surface-identical, coverage passes. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Owner call: every golden command.txt already stamps the generator commit, so any archived fact is reproducible by checking out that commit; a separate freshness tripwire (3 snapshot YAMLs + update/check subcommands) duplicates information the workspace archive (run_sh/, records engine_cli) already holds. gen_facts shrinks ~130 lines.

…s.yaml (output) targets.yaml was carrying two lifecycles: owner-curated experiment inputs and campaign-produced conclusions (36 known: prose blobs, 14 of them copy-pastes of 4 findings; topology verdicts; tooling forensics). They now separate: targets.yaml is pure input (565 -> 346 lines), findings.yaml holds 26 deduplicated findings with applies_to scopes (the fp8-KV two-door paragraph collapses from 8 copies to one entry with 8 scopes). No code consumed the moved content; plan/coverage/dummy-table regressions pass. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The input/output split missed the family-level known_sm90 keys (dsv4/glm/m3 SM90 conclusions incl. the DSV4 dummy false-positive retraction and the M3 sparse_attention_config requirement). targets.yaml now carries no findings prose at all. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
One file answers the project's question per (checkpoint x backend): does the generator's command boot (pass / pass+custom / fail), which extra generate args were needed, why it fails, and the identity the framework actually deployed (attention backend, MoE quant -> executed kernel family, allocated KV dtype, topology). Produced by gen_facts.py --matrix from records + raw + kvcap evidence; summary sglang 83/6/6, vllm 79/8/8, trtllm 60/0/35. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…te-on-bump Owner layout decision: split the consolidated results by framework (three release cadences, three files) under an SM directory (sm100 becomes a sibling later); the probed version is pinned inside _meta and the file is overwritten on version bumps, so a re-run's git diff IS the upgrade audit.

What
op_harness/— a probe-first harness that captures what a serving framework actually does at runtime, instead of deriving it by reading framework source: per-module quant methods, the Python API each op flows through (file:line call chains), and the CUDA kernels under each API boundary. Output is a machine-generated facts archive with provenance, for validating collectors,op_backend_facts.yaml, and generator-rendered configs.Why
Every framework version bump historically broke collectors through silently wrong facts — default backends changing, imports moving, quant identities mis-binding — that code reading failed to catch (and agents reading code reliably get wrong). This makes facts a product of execution: dummy-weight models (depth-cut, width-true so TP divisibility and quant shape checks behave like real checkpoints) driven by generator-rendered engine args (the probe runs exactly what a deployment would — zero translation drift).
What's in the box
targets.yaml— model×checkpoint matrix (DSV4 / GLM-5.2 / MiniMax-M3 / gpt-oss; default/FP8/NVFP4/MXFP4 variants), KV pairing copied from_PROFILE_TO_QUANTgen_dummy_models.py— HF config → per-layer-kind dummy variants with per-layer quant-config renumbering and loud stale-reference checksgen_archive.py— targets → rendered engine args → per-GPU probe queues →archive.jsonl(incremental reruns, generator-commit provenance)probe_runner.py/fpm_adapter.py/trtllm_probe.py— sglang / vLLM / TRT-LLM probes (three-level capture; framework CLI parsers consume the rendered args)make_records.py— curated records: kernel-name normalization, noise filters, orphan-kernel coverage signalSample findings from the first three-backend sweep (SM90, 36 runs)
ModelOptNvFp4FusedMoE) — the "green run, wrong identity" class this exists to catchFp8MoEMethodover fp4-packed weights and crashes at first MoE forward; vLLM routes tofused_marlin_moeand runs; NVFP4 MoE on SM90 is Marlin bf16-dequant everywhere it runsflashmla_sparse/ decodefa3(+ dense-FA3 branch belowindex_topk=2048); explicit fp8 KV →flashmla_kvboth phases with per-step online K-cache quantizationtokens_per_blockis an unvalidated passthrough (64 breaks M3 and DSV4 on vLLM); fp8-profile GLM + vLLM + SM90 renders a deployment with no usable attention backend — the probe doubles as the boot-check the generator lacksStatus / limitations
Draft for design + code review. TRT-LLM engine-arg fidelity (extra_engine_args YAML) pending; identity-only (no perf numbers — that's the collectors' job); tp∈{1,2} real, larger topologies need capability-mocked enumeration; Kimi-K3 adapter pending. Probe-side shims for broken deps in the trtllm 1.3.0rc20 image are documented inline.
