Inline comments:
In `@aic-core/src/aiconfigurator_core/sdk/models/deepseek_v4.py`:
- Around line 99-100: Update the backend validation in DeepSeekV4Model to reject
vLLM for MegaMoE admission, allowing only the SGLang backend. Keep vLLM MegaMoE
support in KimiK3Model unchanged, and preserve the existing ValueError behavior
for unsupported backends.
In `@aic-core/src/aiconfigurator_core/sdk/models/helpers.py`:
- Around line 751-758: Normalize local Kimi-K3 paths to the canonical KIMIK3
identity before _resolve_quant_modes invokes the model helper. Reuse that
identity for both the Blackwell remap and vLLM MegaMoE allowlist validation,
while preserving existing behavior for other models and backends. Add regression
coverage proving a local Kimi-K3 path is handled correctly for SGLang and vLLM
MegaMoE.
In `@collector/sglang/collect_dsv4_megamoe.py`:
- Around line 585-616: Move the vLLM tail initialization out of
vllm_pre_dispatch so the timed serving call only invokes prepare_megamoe_inputs;
apply the mask once after the cached buffer is created, using the case’s fixed
token count and preserving the existing -1/zero tail values. Make the same
change for the analogous copy-lane pre-dispatch path if it performs the same
per-iteration tail masking.
- Around line 880-895: Update main so the version fallback is lane-aware:
preserve SGLANG_VERSION for SGLang runs, but when no version is provided on a
non-SGLang lane, fail fast instead of assigning "unknown". Ensure collection
cannot proceed with an unspecified framework version.
Apply the same fix in `@collector/sglang/collect_dsv4_megamoe.py` around lines 819
- 820: Covers the launcher failing to set or validate the required measured
runtime version.
In `@collector/sglang/dsv4_megamoe/finalize_validated.py`:
- Around line 304-308: Constrain the --framework argument in the argument parser
to accept only the supported sglang and vllm lane values, rejecting any other
input before provenance is generated. Keep the existing default of sglang and
ensure the validated value remains consistent with the systems-data directory
segment used by packaging.
In `@collector/vllm/collect_k3_megamoe.py`:
- Around line 68-76: Restrict the fallback around importing collect_dsv4_megamoe
to package-path failures only: retry with the repository root when the
ModuleNotFoundError identifies “collector”, while re-raising missing dependency
errors such as torch. Update the try/except import logic without changing
unrelated behavior.
- Around line 15-18: Update apply_k3_vllm_defaults() to normalize or inspect
--name=value option forms before validating forced options, rejecting
conflicting values for --pre-dispatch, --framework, and --model-config while
preserving the required kimi_k3, vllm, and VLLM settings for every invocation.
Apply the same fix in `@collector/vllm/collect_k3_megamoe.py` around lines 39 -
58: Covers the same forced-option validation defect for missing and repeated
arguments.
In `@docs/cli_user_guide.md`:
- Line 428: Update the --moe-backend documentation to distinguish model-specific
SGLang coverage: retain the all-supported-systems statement only where
applicable, and explicitly scope Kimi-K3 MegaMoE SGLang support to GB300 so it
matches the support matrix and avoids implying broader availability.
In `@src/aiconfigurator/cli/main.py`:
- Around line 1642-1645: Update _disagg_backend_available so vLLM MegaMoE
disaggregated availability requires
_vllm_megamoe_perf_data_available(decode_system, backend_version) to be true,
while leaving the aggregate vLLM task eligibility unchanged.
In `@src/aiconfigurator/sdk/task_v2.py`:
- Around line 907-936: Update both AFD execution paths, including the pinned AFD
executor and AFD sweep model-config construction, so MegaMoE A-workers use
a_moe_tp_size=1 and a_moe_ep_size=tp_a; reject F-worker candidates whose
f_moe_tp_size is not 1. Ensure _validate_megamoe_backend_support or the relevant
AFD validation rejects unsupported MegaMoE layouts rather than accepting them.
- Around line 917-920: Update the MegaMoE backend validation in the task
initialization flow to inspect every role in roles, not only roles[0]. Retrieve
each role’s backend_name via _role_attr and reject the configuration if any
backend is not "sglang" or "vllm"; preserve the existing ValueError behavior and
message.

Treat OOM failures as unclassified until they reproduce on a clean GPU; only then may the generation-time memory filter exclude them.
Before attributing a framework crash to a framework bug or adding a kernel-limit FIXME, perform a serving-parity audit comparing every collector-built metadata and input field with the serving population site.

collector/**/collect_*.py: Collector code may dispatch by SM/version and recordkernel_source, raise classified exceptions for runtime probes, and apply only the sanctioned memory-feasibility filter; it must not silently skip queued cases or perform other case filtering.
For every queued case, execute it or raise a classified error; branches may change how a case runs but must not change whether it runs.
Use the framework's own serving dispatch to select kernels. Manual backend pinning requires a pinned-version file-and-line citation,kernel_sourcemust record the actually invoked kernel, and invented backend fallbacks are forbidden.
Hand-constructed serving metadata fields and input tensors require citations to the pinned framework's population sites; audit every field against serving code before blaming the framework or addingFIXME(kernel-limit).
The only in-collector filter is generation-time memory feasibility insideget_*_test_cases(), using footprint-versus-capacity arithmetic and live device memory when possible; drops must be counted and logged, and runtimecontinueis forbidden.
Unverified framework kernel limits belong asFIXME(kernel-limit)comments at the invocation site, including the claimed limit, origin, and unverified status; do not encode them in YAML or implement guards from unverified claims.

Timestamp: 2026-02-28T11:44:28.109Z
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.

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.

Learning: In ai-dynamo/aiconfigurator’s vLLM collector modules, keep vLLM imports at top level (not lazily deferred) so a mismatched vLLM version fails during the per-op import and is recorded/classified as a per-op failure (via the existing per-op try/except and __compat gating), rather than altering failure order/granularity. Do not rely on moving vLLM imports into shared helpers like collector/vllm/utils.py to change this behavior. Exception: collector/vllm/collect_mhc_module.py is intentionally “import-vllm-free” (vLLM dependencies were localized) and should remain so to preserve the intended behavior there.

Learning: For the vLLM “collector v2” registries (e.g., collector/vllm/registry.py and any other vLLM collector v2 registry modules), treat the registry entry `versions` field as a retired per-entry versioning mechanism. Code and tests should expect it to be empty/falsy for every registry entry (i.e., review changes to ensure `entry.versions` is not populated). Version pinning for the vLLM backend must be centralized in `collector/framework_manifest.yaml` via `get_collector_runtime("vllm")`, and each vLLM collector module must declare exactly one `__compat__ = "vllm==<manifest_version>"` line matching the pinned manifest version. If relevant, do not misread the framework-manifest test: `test_active_cuda_vllm_collectors_are_exactly_pinned_to_manifest_version` asserts `all(not entry.versions for entry in VLLM_REGISTRY)` and that `__compat__` matches the manifest version (it is not an inverted assertion).

Learning: For DeepSeek-V4 CSA top-k DELTA calibration, key calibration entries by native num_heads and require an exact native-head match. Use index_topk=512 for Flash and index_topk=1024 for Pro; Pro must never consume Flash calibration. Because shipped calibration is Flash-only, leave Pro CSA latency uncorrected and emit a one-time Python warning until Pro calibration is available.

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.

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.

Learning: In ai-dynamo/aiconfigurator’s vLLM collector modules, keep vLLM imports at top level (not lazily deferred) so a mismatched vLLM version fails during the per-op import and is recorded/classified as a per-op failure (via the existing per-op try/except and __compat gating), rather than altering failure order/granularity. Do not rely on moving vLLM imports into shared helpers like collector/vllm/utils.py to change this behavior. Exception: collector/vllm/collect_mhc_module.py is intentionally “import-vllm-free” (vLLM dependencies were localized) and should remain so to preserve the intended behavior there.

Learning: For the vLLM “collector v2” registries (e.g., collector/vllm/registry.py and any other vLLM collector v2 registry modules), treat the registry entry `versions` field as a retired per-entry versioning mechanism. Code and tests should expect it to be empty/falsy for every registry entry (i.e., review changes to ensure `entry.versions` is not populated). Version pinning for the vLLM backend must be centralized in `collector/framework_manifest.yaml` via `get_collector_runtime("vllm")`, and each vLLM collector module must declare exactly one `__compat__ = "vllm==<manifest_version>"` line matching the pinned manifest version. If relevant, do not misread the framework-manifest test: `test_active_cuda_vllm_collectors_are_exactly_pinned_to_manifest_version` asserts `all(not entry.versions for entry in VLLM_REGISTRY)` and that `__compat__` matches the manifest version (it is not an inverted assertion).

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.

On the two provenance findings: 1. collector_hash ghost state — confirmed, and not recoverable as-is. I verified f32c9ebe against every committed state of this branch (all pre-rebase/amend iterations through to tip): none reproduces it. The 2026-08-13 collection ran from working-tree bytes during the EP32-OOM fix + vllm-lane split churn; the exact bytes never landed in git, so I cannot attribute the ghost to a specific file. Rather than papering over it:

Represent wholly unverified operation/backend combinations withOpEntry(unverified=True)and SM-specific validation gaps withunverified_sms=(sm,).
Represent physically impossible hardware or dtype combinations with a positive capability floor incapabilities.yaml; do not use it for framework-version kernel gaps.
Treat OOM failures as unclassified until they reproduce on a clean GPU; only then may the generation-time memory filter exclude them.
Before attributing a framework crash to a framework bug or adding a kernel-limit FIXME, perform a serving-parity audit comparing every collector-built metadata and input field with the serving population site.
Fix proven collector bugs in code; never resolve them with skips, and re-check the dispatch or skip rule.
Investigate unexpected failures at approximately 10%, or sooner when they clust...

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.

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.

What this PR does
This PR adds Kimi-K3 fused MegaMoE modeling and 256 measured GB300/vLLM 0.27.0 rows, moves MegaMoE data into family-specific paths, threads backend selection through CLI and task construction, and adds collector, provenance, documentation, and focused model coverage. The updated head rebases that work onto the compiled Rust single-oracle data plane.
The rebase preserves the feature across a substantial engine migration: the new end-to-end test now proves the Kimi-K3 vLLM MegaMoE path reaches measured silicon rows through the compiled engine, while the model, task, collector, and data-integrity suites remain well targeted and the exact-head CI rollup is fully green.
Why this score
6.2/10, REQUEST_CHANGES. The rebased implementation compiles, the affected Python and data checks pass, and the vLLM compiled-engine path is working. Both prior blocking correctness findings remain unchanged at this head: the published GB300 table is still marked complete even though its collection-time harness cannot be reproduced and differs in a timing-affecting detail, and the default Kimi-K3/GB300 auto sweep still creates a SGLang experiment that deterministically fails because matching MegaMoE rows are unavailable. The rebase also introduced one non-blocking rustfmt issue in its only PR-local Rust diff line.
The rebase joined the MhcTable init onto the closing line of the preceding dsv4_megamoe field; split it back out so the changed hunk passes rustfmt (review: jasonqinzhou, PR ai-dynamo#1553).
… sweep The megamoe auto path seeded the SGLang lane unconditionally while only vLLM went through the MegaMoE data probe. On Kimi-K3/GB300 the default build therefore returned agg_sglang@0.5.16 alongside agg_vllm@0.27.0, and executing the SGLang configuration died at query time with PerfDataNotAvailableError — the gb300 sglang megamoe family stops at 0.5.10 (DeepSeek-V4-Pro rows). Generalize _vllm_megamoe_perf_data_available into _megamoe_perf_data_available(backend, system, version), seed each lane in the auto sweep only when its rows resolve, and gate disagg on decode-side MegaMoE rows for both backends (keeping the aggregate task alive). Regressions: the lane-omission sweep test now runs against the real probe, plus a query-level test that exercises the measured query until the old failure surfaces (review: jasonqinzhou/coderabbit, PR ai-dynamo#1553).

What this PR does
This PR adds fused Kimi-K3 MegaMoE modeling and measured GB300/vLLM 0.27.0 coverage, with collector provenance, compiled-engine support, CLI task generation, and documentation. Since the previous review, it has been rebased onto queryable version slots and now resolves default MegaMoE lanes into the slot carrying measured fused-module rows while bypassing separate DeepEP A2A requirements for that fused boundary.
The rebase follow-up correctly recognized both integration boundaries: the default no-pin Kimi-K3 auto task now reaches the vLLM next-slot data, and the focused measured execution test proves that the fused module answers from silicon rows.
Why this score
6.8/10 quality assessment, BLOCKED packet. The required Claude Fable lane could not be verified: claude-fable-5 was requested, but only Claude Sonnet 4.6 and Claude Haiku 4.5 were observed, so the skill forbids a non-blocked canonical recommendation. Independently, Codex confirmed one current-head P1: explicit query-slot aliases such as --backend-version next are passed directly to a filesystem probe, causing the valid GB300/vLLM MegaMoE lane to be dropped. The previous provenance finding remains fixed; 128 focused tests, all 26 exact-head checks, and all 18 review threads are otherwise clean.

Opens the vLLM lane of the fused DeepGEMM MegaMoE module (ref ai-dynamo#1462) and ships the first measured Kimi-K3 dataset for it (gb300, vllm 0.27.0). Modeling: kimi_k3/deepseek_v4 build the fused DeepSeekV4MegaMoEModule under moe_backend=megamoe with per-backend pre_dispatch (vllm vs sglang_jit); gate/top-k, latent projections and shared experts stay outside the measured boundary. K3 MXFP4 quant remap is moe_backend-aware (vLLM plain lane keeps w4a16 Marlin; vLLM+MegaMoE gets w4a8_mxfp4_mxfp8 on Blackwell). CLI gains --moe-backend on default/exp/estimate (SOL sidecar degrades to measured-only columns on measured-only lanes) and --backend auto enumerates vLLM only for models whose measured vLLM MegaMoE rows resolve (today: Kimi-K3 on gb300). Rust: Dsv4MegaMoeTable resolves its single primary through resolve_op_sources, honoring the family-first layout (<system>/megamoe/ <backend>/<version>). Previously the compiled engine hard-pointed at the legacy dir and every vLLM MegaMoE query came back empty. Rust unit tests plus a run_agg E2E regression pin the resolution. Collector (verified in-container on GB300/SM103 @ vllm 0.27.0): collector/vllm/collect_k3_megamoe.py is a thin wrapper over the shared DSv4 harness forcing kimi_k3 + pre_dispatch=vllm + framework VLLM. Serving truth: vLLM's own triton prepare_megamoe_inputs is the timed pre-dispatch (not sglang's deep_gemm JIT copy), DeepGEMM is reached via vendored vllm.third_party.deep_gemm, and SiTU is passed as activation="situ" with activation_clamp=None. Harness memory rewrite (EP=32 x 32768 cgroup OOM killers): balanced_logits one-hot cube -> scatter_add_ (bit-identical at these strides), build_routing_plan keeps the randperm RNG stream and does per-rank gather only (peak host RSS 177GiB -> 11.1GiB/worker); a legacy-oracle equivalence test pins it. Data/registry: new megamoe family in the op catalog; the 3 pre-existing MegaMoE tables move to <system>/megamoe/ (reuse.yaml split accordingly) and this adds the 4th: gb300/megamoe/vllm/0.27.0 with 256 rows, EP=4/8/16/32 x (24 ctx + 40 gen) x 4 distributions, w4a8_mxfp4_mxfp8/fp8_fp4, validate_perf PASS per EP and merged. Manifest megamoe family pinned to vllm 0.27.0 (amd64+arm64 digests). Verified: 3990 python + 461 rust tests green, ruff clean, backend_facts --check and check_collector_data R1-R6 green.

Rebase fallout from ai-dynamo#1578/ai-dynamo#1581 on main, both invisible at task-build time and only firing at CI unit (test_kimi_k3_auto_megamoe_generated_ task_reaches_measured_vllm_rows): 1. Cross-node EP gate vs the fused module: ai-dynamo#1578 made resolve_model_ config_moe_comm raise PerfDataNotAvailableError for cross-node EP without DeepEP A2A coverage. The MegaMoE module's measured boundary already contains its A2A (symm-buffer dispatch/combine inside the dsv4_megamoe_module rows), so the resolver now returns early for moe_backend='megamoe' — the module table itself pins the covered EP axis and dies loudly at its own query beyond it. 2. Version slots vs the megamoe drop: under ai-dynamo#1581 get_latest_database_ version resolves to the CURRENT slot (gb300/vllm 0.24.0), while the megamoe family is a single-op development drop living in NEXT (0.27.0) — backward fill is never forward, so the auto-lane probe missed the table and the lane died before seeding. New _megamoe_lane_version probes requested -> current -> next and the megamoe lanes (auto and explicit backend) now run the Task at the resolved slot version; _megamoe_perf_data_available wraps it and keeps its signature for the disagg decode-side gate and tests.

Fixed in-place (amended): DSv4 stays SGLang-only at both the model and Task gate (no vLLM DSv4 rows exist); Kimi-K3 identity is architecture-keyed, so local/offline checkpoint mounts qualify equally with the hub id (quota remap + Task allowlist + auto-sweep gate all share it); MegaMoE tail mask hoisted out of the timed region for both pre-dispatch lanes (note: shipped rows predate this hoist and carry a small pessimistic tail-mask overhead at small decode shapes — refresh on re-collection); vllm lane hard-requires --version (no "unknown" rows);
