Validate exact source selections against model metadata and the constructed native operation graph before unsupported configurations can fall back. Preserve the source through external-FPM AFD validation and explicitly reject legacy or fixed companion paths that cannot consume it. Document the selector contract and cover the actual model, memory, Task, and runner consumers. Signed-off-by: Yiming Liu <yimingl@nvidia.com>

Inline comments:
In `@crates/core/src/perfmodel/fpm/config.rs`:
- Line 279: Update the model-selection validation around
`self.moe_kernel_source` so a pinned MoE source cannot select regression,
including through `best_available` after native construction fails. Preserve
successful op-level selection for `auto`, and add coverage for explicit
regression with a pinned source and `auto` with native construction failure.
In `@python/aisimulate/src/aisimulate_core/sdk/models/blocks/moe.py`:
- Line 405: Update build_moe_block_ops to read the optional moe_kernel_source
selector with a None fallback when duck-typed configs omit the attribute.
In
`@python/aisimulate/src/aisimulate_core/systems/data/gb300/moe/sglang/0.5.17/collection_meta.yaml`:
- Around line 36-46: Update load_moe_parquet so only the designated default
lane, moe_torch_flow_min_latency, is inserted into default. Keep all other named
lanes in by_kernel_source for explicit selection through query_kernel_source,
leaving query()’s unselected default grid limited to the designated lane.
In `@python/aisimulate/src/aisimulate/sweeper/config.py`:
- Line 542: Update SearchSpace validation for moe_kernel_source so
whitespace-only values are rejected when the search configuration is loaded,
before candidate resolution; preserve support for None and nonblank sources.
In `@python/aisimulate/tests/unit/sdk/test_compile_engine_mtp.py`:
- Around line 122-124: Update the MoE test using compile_engine to run a
supported MoE model without stubbing build_engine_spec_json, then assert the
serialized engine specification includes the expected moe_kernel_source and MoE
specifications. Preserve the existing test setup only where needed for unrelated
dependencies.

- The compatibility reference maps
sglang_flashinfer_trtllmtosglang_flashinfer_trtllm_moe, using backendflashinfer_trtllm_gen. [::ai-dynamo/aiconfigurator::] (collector/kernel_source_backends.yaml:129,collector/sglang/collect_moe.py:602,689) - Existing facts use this lane for GB300 SGLang MoE measurements, but the recorded version is 0.5.14; no 0.5.17 fact was found. [::ai-dynamo/aiconfigurator::] (
collector/op_backend_facts.yaml:1568-1569) - The frozen reference remains at engine schema version 15, enforced by Rust and cross-package tests. The PR’s version 20 is therefore not compatible with this frozen artifact and should not be expected to decode its new engine specs. [::ai-dynamo/aiconfigurator::] (

moe-runner-backend: flashinfer_trtllm; both aggregated and disaggregated configurations use this backend. [::ai-dynamo/dynamo::] (recipes/qwen3.8-2.4t-a95b-fp8/sglang/agg-gb300-chat/deploy.yaml:10,23,30,sglang/disagg-gb300-chat/deploy.yaml:10,24,43,58,62) - Dynamo contains no
moe_kernel_sourceconsumer; its deployment contract currently selects the backend, not the new exact measurement lane. This data addition should therefore remain compatible with existing Dynamo recipes, but exact-source selection will not be exercised there.

1199-1199: 🗄️ Data Integrity & IntegrationThe schema-v15 compatibility concern is refuted.
ai-dynamo/aiconfiguratorv15 applies to its owncompile_engineandAicEnginepair. Its documentation describes that pair as a separate maintenance-only compatibility surface and directs new integrations to AISimulate. AISimulate keeps its own Python and Rust engine consumers in lockstep at schema 20. This diff only addsmoe_kernel_sourceto the engine identity and does not send AISimulate specs to the standalone AIC consumer.

The JSON and reproducible script provide inspectable evidence without adding a synthetic audit file to this data PR. I did not run the native-consumer audit. I also could not independently compare the original columns: the historical Parquet object was unavailable in this checkout. Those two claims remain supported by your supplied audit, not by my independent checks. You are interacting with an AI system. |
|
The PR description now follows the required headings and includes the review map, contract and rollback notes, exact validation commands/results, evidence classification, current reviewed commits, CI status, and AIC-1781 tracking. The detailed binary audit and reproducible real-native consumer checks are linked from the description. @coderabbitai Please recheck the remaining description/review-evidence warning; the commit and measured data have not changed. |

- Around line 680-687: In the row-loading loop, call moe_default_eligible before
kernel_source_ok so every row’s default_eligible value is validated, including
rows excluded by the kernel-source allowlist; keep the existing filter and error
behavior unchanged.

aisimulate==0.12.0inpyproject.toml:17andaisimulate-core = "=0.12.0"inCargo.toml:59-60. The new eligibility/data contract therefore requires a compatible AISimulate release and downstream pin update before Dynamo can consume it. [::ai-dynamo/dynamo::] - Planner and replay AIC configuration expose
moe_dtypebut no kernel-source selector (aic_adapter.py:248-275,replay.rs:299-330). They cannot explicitly request the new FlashInfer lane. [::ai-dynamo/dynamo::]

[::ai-dynamo/aiconfigurator::]- The shared-layer contract treats named kernel sources as reusable lanes and
kernel_source=defaultas fallback (docs/perf_database/collector-v3-op-centric-design.md:365-371,perf_database.py:1245-1249). Explicitly ineligible rows must not enter those default/fallback paths. [::ai-dynamo/aiconfigurator::]

2627-2632: The legacy-inheritance merge can duplicate rows when the pandas key types differ.
new_df.merge(annotations, on=identity, how="left")uses the identity columns. After the schema check, both sides have the same Arrow types, so the key types should match. Ifannotationsstill contains duplicate keys, the row count grows.drop_duplicates(keep="last")runs first, so duplicate keys cannot remain. A NaN-valued identity cell can still fail the left merge in pandas. For example, an emptydistributionorkernel_sourcecell parsed as null becomes NaN or None. The merge then treats NaN keys as equal, butdrop_duplicatesbehavior can differ between NaN and None. The current behavior is acceptable. No change is required.

Current-head refresh evidence (2026-09-29)GB300 data head Fresh native audit against this main: 56,862 automatic outcomes unchanged; 24,624 exact-source latencies equal the recorded milliseconds; default views and coverage unchanged. All 324 TP32 rows remain accessible explicitly and rejected by unset/Triton SILICON selection. The native binary was freshly built from merged code Collector R1–R7, all 2,153 backend-fact slices, and focused tests pass. Independent reviews and current-head hosted CI are separate gates; this comment does not claim those complete. This is real-native validation, not new GPU collection or predictive-accuracy evidence. Machine-readable data audit: keys, every shape, units, hashes, counts and anomalies{

Post-review metadata refresh: exact head

Codex review completed on exact head
The full generated manifest includes inherited main catch-up (eight SGLang-only entries and prior count drift); it introduces no new cross-framework reuse. The catalog clarification preserves backend names and measured facts. The inherited malformed-eligibility reader gap is separately tracked on AIC-1781 and remains unfixed; it is absent from these valid data rows and not introduced by this diff. Full evidence and the explicit inherited/new split are in the current-head audit. No unresolved P0/P1 findings. This is technical review evidence, not a substitute for the required human approval, CodeRabbit completion, current-head Full CI, or GitHub merge gates. |

moe_dtypebut nokernel_source(components/src/dynamo/planner/core/perf_model/aic_adapter.py:264,lib/bindings/python/rust/llm/replay.rs:299-330). The new explicitly ineligible FlashInfer lane cannot be selected through those existing interfaces. [::ai-dynamo/dynamo::] - GB300 Qwen SGLang recipes explicitly select
flashinfer_trtllm(recipes/qwen3.8-2.4t-a95b-fp8/sglang/agg-gb300-chat/deploy.yaml:23,30,.../disagg-gb300-chat/deploy.yaml:24,62), matching the backend identity used by the new data. [::ai-dynamo/dynamo::]

- The frozen SGLang catalog documents
flashinfer_trtllm_genfor{bf16, fp8, mxfp8, nvfp4, mxfp4}but omitsfp8_block(collector/op_backend_catalog.yaml:134-143). In contrast,fp8_blockis recognized globally and documented as a supported quantization mode (tools/support_matrix/support_matrix.py:61,375-376,docs/advanced_tuning.md:48-49). This is a compatibility-reference divergence to keep intentional for the new AISimulate catalog entry. [::ai-dynamo/aiconfigurator::] - Named kernel sources are
shared, whilekernel_source=defaultisshared_fallback; both are inherited by HYBRID reuse (docs/perf_database/op-kernel-sources.md:3-8,tools/perf_database/generate_perf_data_reuse_manifest.py:547-564). The new named FlashInfer rows therefore need explicit source/eligibility handling rather than being treated as default fallback measurements. [::ai-dynamo/aiconfigurator::]

1352-1352: 🗄️ Data Integrity & IntegrationThe incompatible-reader path is blocked by the version pins.
The reviewed AISimulate artifact is version
0.13.0, while Dynamo pins both AISimulate distributions to0.12.0. Dynamo cannot consume this manifest or its opt-in rows until it adopts0.13.0or a later compatible release.

Why and what changed
Adds the complete dedicated GB300 SGLang 0.5.17 FP8 FlashInfer MoE sweep for AIC-1781: 3,159 measurements (117 shapes × 27 token counts) for the Qwen3.8-Max deployment-pinned
sglang_flashinfer_trtllm_moelane.The diff against current main is five data/metadata files: the system's
moe_perf.parquet, itscollection_meta.yaml, one observed FP8 source/backend entry incollector/op_backend_facts.yaml, a pinned-source catalog clarification that SGLangfp8includesfp8_block, and the complete regeneratedperf_data_reuse_manifest.yaml. No executable code, collector behavior, or golden is changed. Prerequisite #326 is merged; this branch includes it via main.Review map and compatibility
Risk: high, because measured data and selection eligibility are product behavior. Start with
python/aisimulate/src/aisimulate_core/systems/data/gb300/moe/sglang/0.5.17/, then the matching registry line, catalog clarification, and generated manifest. Current-head machine-readable audit and native consumer evidence cover all shapes, keys, units, hashes, anomalies, binary data, and inherited manifest catch-up.The optional Boolean
default_eligibleis true on all 9,153 existing rows and false only on the 3,159 new FP8 FlashInfer rows. All 324 TP32 points remain available through explicit kernel-source selection. Existing Triton and NVFP4 defaults are unchanged; automatic selection must not gain TP32 FlashInfer coverage. The collection sidecar remains schema v2, and the curated source-to-backend mapping is unchanged.Intended consumer: this PR delivers the new opt-in FP8 rows for native AISimulate source-specific, op-level queries using
moe_kernel_source="sglang_flashinfer_trtllm_moe"and an eligibility-aware reader. It does not add or certify selector plumbing in Dynamo's Planner or replay adapters. Downstream integrations must adopt compatible AISimulate reader support and explicitly forward the source selector before claiming these opt-in measurements; automatic selection remains unchanged. This boundary applies to the new FP8 rows, not to every existing NVFP4 measurement sharing the same source label. Retaining a selector in a regression configuration is not proof that the estimator used this measured lane; the existing estimator contract remains unchanged.Keep the eligibility-aware reader while these opt-in rows are installed. A reader rollback must restore the pre-PR Parquet, sidecar, and system-specific registry entry together; merely dropping the eligibility column is unsafe with old readers.

Later main advances in this sequence contain measured data only; the executable code is identical.6530620b3c136953af1d84b541804c74d2d0f296. No measurement was removed, rescaled, recollected, or replaced.The audit link contains exact runnable commands and the native harness. Original production Slurm/OCI collection, pinned image, collector closure, case plan, and zero-error evidence remain in the earlier collection and annotation audit and unchanged sidecar. The refresh checks are loader/selection and prediction-regression validation, not new GPU benchmarks or a predictive-accuracy claim.
Tracking and landing
Related: AIC-1781, association approved by the user. Closes: none; the original issue has broader collection scope.
Landing order: merged code #326, then B200 #296, GB300 #298, and GB200 #301. Each data PR is refreshed and validated against the preceding main before squash merging. Required human CODEOWNER/domain approval, resolved conversations, and exact-head Fast/Full CI remain independent merge gates.
