📝 SummaryRisk: Medium. The three areas that need the most human attention are:
Changed behavior
Public contracts
Evidence and remaining gapsThe source confirms schema version 21, exact-lane lookup, source-specific token and quantization validation, blank-source validation, and rejection of sources with The author reports local test and check results, including that the previously failing unit shard passes after updating the Qwen3.8 FP8 expectation. No test output or fresh hosted CI result was supplied here. The objectives state that fresh exact-head review and hosted Full CI remain required. No current review findings were supplied, so review severity counts are unavailable; bot review is not approval. Merge readinessThe objectives report a Repository Policy CI failure because the numerical-sentinel baseline SHA is absent from the runner checkout, and report the same failure on WalkthroughThe change adds optional MoE kernel-source selection across Rust and Python configuration, exact performance-data lanes, model construction, memory estimation, serialization, and engine-cache identity. It adds validation and regression coverage for supported and rejected configurations. ChangesMoE kernel-source selection

CI note: Repository Policy is failing because the checked-in numerical-sentinel baseline SHA af91885 is absent from the runner checkout. The identical failure is already present on main at d9f1580 (run 35316768430); this PR does not modify the sentinel manifest or CI workflow. The dependent Fast CI Success failure follows from that policy job. All PR-specific static and format checks pass. |

In `@crates/core/src/perfmodel/operators/moe.rs`:
- Line 364: Update MoeOp::silicon_pr to reject the moe_torch_flow_min_latency
source returned by query_kernel_source unless num_tokens is at most 128, the
mode is MoeQuantMode::Nvfp4, and the operation is gated; keep all other exact
kernel-source lanes unrestricted.
In `@crates/core/src/perfmodel/perf_database/moe.rs`:
- Around line 574-583: Provide numerical parity evidence for the explicit
kernel_source selection in grids_for_kernel_source: run both required parity
suites, include the exact commands and results, and document either an explained
golden diff or hand-derived oracle evidence. Do not rely on the synthetic lane
test as a substitute.

Linked repositories findings
ai-dynamo/dynamo
- The planner’s native AIC adapter emits an AIC configuration and cache identity without
moe_kernel_source(components/src/dynamo/planner/core/perf_model/aic_adapter.py:238-300). Dynamo therefore cannot select this lane through its planneraic_perf_modelconfiguration; this is an integration omission only if planner exposure is intended. [::ai-dynamo/dynamo::] - Dynamo pins
aisimulate==0.12.0(pyproject.toml:17), so the new schema requires coordinated package release/version updates before downstream native-AIC consumers can use it. [::ai-dynamo/dynamo::] - No Dynamo call sites were found for
build_model_configor the new selector, and its replayEngineSpecis a separate local model. [::ai-dynamo/dynamo::]
ai-dynamo/aiconfigurator
- The frozen compatibility reference still expects
ENGINE_SPEC_SCHEMA_VERSION = 15(aic-core/rust/aiconfigurator-core/src/config.rs:72) and rejects other versions during bincode loading (aic-core/rust/aiconfigurator-core/src/engine/spec.rs:125-130). It cannot consume specs produced with the PR’s version 19, as expected for a frozen migration reference. [::ai-dynamo/aiconfigurator::] - Existing
build_model_configcallers use keyword arguments (aic-core/src/aiconfigurator_core/sdk/memory.py:288-302), so the added optional parameter does not create an observed positional-call break. [::ai-dynamo/aiconfigurator::]

One confirmed correctness issue: an explicit low-latency kernel source bypasses the gated-operation eligibility check in both silicon and empirical selection. This independently reproduces the existing low-latency-lane concern and shows that fixing only silicon_pr is insufficient. The existing Rust MoE suite passed (150 tests); the targeted non-gated regression fails in SILICON, EMPIRICAL, and HYBRID. Reviewed commit 380e394.

grids_for_kernel_sourceadds a new table-selection path keyed bykernel_source. Table/selection-rule changes are numerical behavior under the parity rules for this crate. The PR states no golden fixtures changed, but that alone does not cover the newExactKernelSourcelane itself, which is new behavior, not a preserved default.Run both parity suites and attach an explained before/after golden diff or a hand-derived oracle for at least one exact-kernel-source query, beyond the synthetic unit test already in this file.

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.

@coderabbitai review Please review current head 6f56d9d. The unsupported-graph and AFD alias-propagation findings are fixed, with real consumer regressions and durable API docs. AFD legacy/fixed paths reject exact-source requests; external FPM preserves the source into canonical rejection before file access. Independent fix-diff and whole-branch Codex reviews are clean. Exact-head numerical parity passes 301 engine-step and 85 compile cases; the PR description includes exact commands and the hand-derived 1.984375 ms exact-source oracle. The Dynamo integration thread was dispositioned separately under the standalone repository contract; no Dynamo planner support is claimed. |

Rebase and review follow-up complete at 6f56d9d. Fast CI, Full CI, CodeRabbit, DCO, ownership validation, and advisory prediction performance all pass on this head. Both independent Codex review layers are clean; numerical parity passes 301 + 85 cases with unchanged goldens. All conversations are resolved and the branch is current with main. Required CODEOWNER approval is the remaining merge gate; existing owner-team review requests are pending. The case/data PRs #283, #296, #298, and #301 were also restacked with independently verified byte-identical content. No merge was performed. |

Conflict resolution — 2026-09-24Resolved the conflicts against main The resolution retains both the exact MoE kernel-source selector and upstream DeepSeek V4.1 FPM identity/attention selector. Both builder options remain keyword-only. Upstream's FPM change already uses EngineSpec schema 20, so the combined wire layout now uses schema 21; tests cover round-trip preservation and rejecting stale schema-20 payloads before decoding. Performance data and numerical goldens are unchanged relative to main. Validation on the merged production tree and final test fix:

The stale collector assertion behind the AMD64 and ARM64 unit-shard failures in Full CI run 35949729896 is corrected in Local verification on macOS arm64: the original assertion reproduced before the fix and passes afterward; both related collector test files pass all 91 tests; the original unit-shard selection passes with 1,930 passed and 6 skipped. Full Python Ruff lint and formatting checks pass. An independent task reviewer reproduced the old failure and verified the corrected expectation against the collector declaration, including unchanged BF16/NVFP4 behavior. Fresh exact-head review and hosted Full CI are required; the earlier CI results do not validate this new commit. This update does not claim merge readiness. @coderabbitai review |

Upstream ai-dynamo#282 (exact MoE kernel source) took schema 21; decode context parallelism is renumbered to 22 (constant, spec.rs note, op field doc comments, Python schema test). The other conflicts were adjacent additions: `validate_parallel_size` next to `normalize_kernel_source` in config.py, `moe_kernel_source` next to the keyword-only CP knobs in build_model_config, and the DCP rewrite ahead of the kernel-source graph check in get_model. Both sides kept everywhere. Upstream's new spec.rs test asserted `schema_version == 21` literally; it now compares against ENGINE_SPEC_SCHEMA_VERSION like its neighbours. Its positional-arguments test for ForwardPassPerfModelConfig lists the keyword-only defaults explicitly, so cp_size / dcp_size join that list.

Part of AIC-1781. Add an optional
moe_kernel_sourcecontrol to select an exact collected fused-expert kernel source, includingsglang_flashinfer_trtllm_moe, while preserving the existing default when unset.This is separate from AIC-1885's
moe_backendexecution/topology control. The selector propagates through task v1/v2, canonical perf-model configuration, CLI/replay/sweeper consumers, model builders, cache identity, engine serialization, PyO3, and Rust lookup. An unavailable explicit source fails instead of substituting another source; incompatible large-EP and whole-forward FPM interpolation overrides are rejected.Exact-source table selection applies to SILICON, EMPIRICAL, and HYBRID queries. SOL remains a pure roofline calculation with
Source::Sol, independent of measured-source rows. Retaining the source in an untrained FPM regression's identity does not make that estimator ready or establish kernel-source prediction support.Performance-data changes remain in dedicated PRs: B200 #296, GB300 #298, and GB200 #301, stacked on case declaration #283. No collected data or numerical golden fixtures change here.
Conflict resolution and review fixes
Rebased onto
e8828036e3d32d8361e2abb819e0ee60e569f518. The SDK engine-identity conflict preserves both upstreamfpm_parquet_pathand this PR'smoe_kernel_source. The engine-spec schema is v20, incremented from upstream v19.Explicit
moe_torch_flow_min_latencyselection now requires a gated NVFP4 operation and at most 128 gathered tokens. Validation runs before both silicon lookup and empirical transfer, returningInvalidEngineConfigso HYBRID cannot substitute a fallback. Tests cover SILICON, EMPIRICAL, and HYBRID; 128/129-token boundaries; attention-DP gathering; non-gated, FP8, and NVFP4-WO rejection; and unrestricted FlashInfer FP8 selection.The embedded-Python integration fixture now initializes the new field, and the separately built Rust public-API test expects schema v20. The new source argument is keyword-only in both
build_model_configand the canonicalForwardPassPerfModelConfig; regression tests freeze all 17 and 31 pre-existing positional arguments, respectively. Python rejects whitespace-only labels, matching Rust, without trimming valid exact labels. Current schema comments and the external schema-history assertion are synchronized.The external-review follow-up in
6f56d9drejects sources ignored by dense, MegaMoE, large-EP, or constructed dense-only graphs. Native composite inspection preserves supported DeepSeek-V4.1 stage children. Model-aware compilation and memory validation use typed invalid-configuration errors, including across the real Rust/PyO3 fallback boundary. Legacy Task whole-forward FPM rewrites reject the selector. AFD companion tests cover both accepted source aliases and both roles: ordinary/fixed timing rejects the unsupported choice; external FPM forwards it into canonical incompatibility validation before file access. Source-unset and unrelated existing fixed-timing controls retain their behavior. The durable API contract and exhaustive Sweeper fixture are updated.Numerical evidence

Exact-source SILICON/HYBRID interpolation at 127 tokens must yield

Before the fix, all three new invalid-request tests reproduced forbidden success at 1 ms; afterward they reject the request.

Hosted Fast CI, CodeRabbit, Full CI, and required CODEOWNER approval remain separate merge gates; local review and parity results do not replace them.
The full external review at
350b26eraised two confirmed local defects: unsupported graphs ignored an explicit source, and the AFD companion dropped both aliases. Independent reproductions reached the real graph and terminal consumers. These are fixed in6f56d9d, with both fresh independent fix-diff and whole-branch reviews clean. Unsupported consumers reject the explicit request rather than silently discard it. Updated hosted review and exact-head CI remain required before merge.The downstream Dynamo planner request is outside this repository's standalone contract and this PR's scope. This PR does not claim Dynamo planner kernel-source selection support or update Dynamo's adapter, cache identity, or dependency pin; those require separate downstream work.
CodeRabbit completed the
6f56d9dreview. Its remaining minor request concerns source-unset EPLB/slots/backend validation that independently reproduces unchanged on maine8828036and this head (identical dense 28-operation graphs); it is not an introduced regression. All review threads are dispositioned.Final hosted validation at
6f56d9d: Fast CI and Full CI pass, as do CodeRabbit, DCO, the generated ownership check, and advisory prediction performance. Full CI ran through the trustedpull-request/282push, whose SHA equals the reviewed PR head; no manual diagnostic run substitutes for merge-gate evidence. At 11:00 UTC on 2026-09-21, the PR is conflict-free and current with main, with no open review conversations. Required CODEOWNER approval is the remaining merge gate; review requests are pending and no merge was performed.
