Changed behavior and contracts
EvidenceThe supplied context reports passing Rust, Python, SDK, application, sweeper, CLI, runner, installed-wheel, replay, and regression suites. It also reports coverage for estimator availability, data-root discovery, version resolution, KV loading, and capacity caching. The status and diff-stat command produced no entries, which indicates no reported working-tree changes. Review severity counts are unavailable. The supplied bot summaries are not approval. Evidence still missingTests were not independently verified. Dynamo integration and full CI remain pending. A pre-commit formatter discrepancy remains. Merge readiness is incomplete. WalkthroughChangesThe pull request replaces separate native and regression construction paths with typed, configuration-driven forward-pass estimator APIs. Rust owns validation, selection, fallback, provenance, readiness, and regression controls. Python, AIC, Sweeper, replay, and deployment flows use canonical configuration and preserve resolved estimator metadata. Forward-pass estimator API

Requesting changes on b927ff97c09d8bf1d0c8f6e80d00ef92ff1b8d82 against base/merge-base 920453e6a6cfb958eae2b2f725db9b767788b4c7. The shared construction API is in place, but four independently reproduced defects prevent the promised consistent estimator selection and identity from reaching every consumer. Two are demonstrated regressions of existing behavior; two are incomplete parts of the new contract. Each inline comment includes a concrete example, observed output, current-versus-required behavior, and a runnable reproduction using the real native implementation.
Standards — two P1 findings
- F1: Auto selects an unusable op-level model on an FPM-only dataset. The first query fails with missing GEMM data; explicit FPM interpolation answers the identical query at 4.5 ms. Availability must be established during construction.
- F2: An existing globally configured custom systems root is discarded by the new default during estimator construction. The same public Sweeper request produces one feasible candidate on base versus zero on head, despite passing preflight in both.
Spec — one P1 and one P2 finding
- F3 / P1:
backend_version: currentis resolved in timing configuration but remains an alias in deployment metadata. Base completes the example request in 37.713045 ms; head raises a version conflict. An explicit0.24.0works on both. - F4 / P2: KV-relative search drops explicitly supplied systems roots during capacity calculation. The candidate materializes with fixed concurrency but fails with both
kv_load_ratio: 0.5and1.0. The failure precedes application of the ratio.
Validation
| Suite | Independently observed result |
|---|---|
| Application / Sweeper / CLI / runner | 796 passed; 5 declared cross-repository Dynamo skips |
| SDK and Python public API | 90 passed |
| Rust library with Python embedding | 1,390 passed; 1 ignored |
| External Rust public API | 7 passed |
| Engine-step and compiler parity | 383 passed |
| Total existing tests | 2,666 passed, 5 skipped, 1 ignored |
These green suites do not cover the four reproduced combinations. The code embedded in the inline comments was rerun before posting; F2 and F3 were also rerun against separately built base runtimes. Local verification used macOS arm64, Python 3.12.12, and native development builds. Synthetic fixtures and shipped performance data establish software behavior here, not predictive accuracy or production-wheel certification.

The request for changes is based on these four code findings. CI and downstream release coordination remain separate merge prerequisites. Standards: 2 findings, worst severity P1. Spec: 2 findings, worst severity P1.

Inline comments:
In `@crates/core/src/perfmodel/engine/runtime.rs`:
- Around line 511-523: Update validate_forward_pass_readiness to validate the
required op-level tables when fpm_ops() is None, according to the configured
database mode. Propagate missing-table errors as candidate-construction failures
so best_available can fall back to FpmInterpolation, while preserving the
existing fpm_forward validation for engine-level candidates.
In `@crates/core/src/perfmodel/fpm/regression.rs`:
- Line 615: Extend the regression test around fit_linear_active_set and
BucketedRegression::predict to configure a non-default
ForwardPassPerfOptions::regression_ridge_scale, use a collinear input, and
assert the hand-derived fitted result or prediction. Ensure the configured value
is passed through regression_options() rather than relying on the default 1e-9.
In `@docs/core-api.md`:
- Around line 298-303: Update downstream Dynamo callers and wheel smoke tests
from the legacy best_available(config, perf_options) and
from_regression(options) APIs to the canonical single-config API, including the
required config constructors and EngineConfig migration helper. Align the
dependency pin with the coordinated canonical release, or enforce the documented
release gate until all downstream migrations are complete.
In `@docs/sweeper/configuration.md`:
- Around line 175-180: Update the database mode table near EstimatorPolicyConfig
to document the accepted SOL_FULL mode and its resolution behavior, or validate
and reject SOL_FULL at the public Sweeper boundary if it is unsupported; keep
the documented modes aligned with the configuration contract.
In `@python/aisimulate/src/aiconfigurator_core/sdk/engine.py`:
- Around line 442-461: Update compile_engine’s get_model call to classify
caller-control validation errors, including invalid model_config.forward_model,
as InvalidEngineConfigurationError while leaving model-path and
model-construction failures unwrapped. Reuse the existing
ValueError/TypeError/KeyError conversion boundary or an equivalent narrow
boundary around the caller-control checks in get_model.
In `@python/aisimulate/src/aiconfigurator_core/sdk/rust_engine_step.py`:
- Line 359: Update _optional_json_dumps to convert non-None Mapping values with
dict(value) instead of calling value.copy(), ensuring all Mapping
implementations—including mapping proxies—serialize correctly while preserving
the existing None behavior.
- Around line 161-174: Add bucket_shape and regression_ridge_scale fields to
ForwardPassPerfOptions with the specified types and defaults, ensuring to_dict()
includes them for legacy configuration serialization.
In `@python/aisimulate/src/aisimulate/aic.py`:
- Line 92: Update the timing-model configuration assembly at the
lowered["timing_model"] assignment to resolve
BackendDeploymentSpec.backend_version through the same slot resolver used for
provenance before the runner performs its literal comparison, while preserving
other resolved and memory fields.
In `@python/aisimulate/src/aisimulate/config/engine.py`:
- Line 276: Update the validation guard around the worker timing policy to
compare the derived estimation_mode, allowing fpm_interpolation only when
forward_model is the legacy "fpm" value; do not allow other non-op_level modes
through that legacy path. Preserve the existing acceptance of None and
"op_level" in the guard.
In `@python/aisimulate/src/aisimulate/recommend.py`:
- Line 814: Preserve the None sentinel for the core default in the timing
configuration: update the logic around the resolved estimator’s transfer_policy
so lists are copied only when a policy is provided, while None remains None.
This ensures _worker_engine_args reconstructs ForwardPassPerfModelConfig with
the documented default rather than an empty policy.
In `@python/aisimulate/src/aisimulate/sweeper/deploy.py`:
- Around line 124-128: Update the timing-model construction in the
forward_pass_estimator branch so memory_fraction_field is copied into the
canonical timing config only when it remains present in payload, preserving its
existing payload value. Do not inject the default memory fraction for candidates
with pinned {role}_num_gpu_blocks; keep tensor_parallel_size and dp_size
handling unchanged.
In `@tests/sweeper/test_search.py`:
- Around line 1029-1035: Extend the orchestration tests around the
_isolate_estimator_data_for_orchestration fixtures and related tests in
test_search.py, test_search_providers.py, test_unified_optimizer.py, and
test_result.py with focused non-empty resolved estimator specifications. Assert
that estimator identity, configuration, and provenance survive candidate
materialization, provider conversion, role-specific replay input, and result
provenance; retain the empty resolve_candidate stub only in tests that do not
inspect these fields.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick winInclude nonempty role controls in the nondefault-policy check.
A policy-only control, such as
role_estimator_controls={"agg": {"database_mode": "HYBRID"}}, leaves the currentnondefaultexpression false. This allows the control with an AFD deployment or an encoder search.ForwardPassEstimatorResolver.resolve_candidatethen returns{}for those paths before_requestapplies the role control, so the requested estimator policy is ignored.The existing per-role check already rejects nonempty controls paired with custom timing. Add the missing role-control term for the AFD and encoder paths:
Proposed fix
nondefault = ( self.database_mode != "SILICON" or self.transfer_policy is not None or self.systems_paths not in (None, ["default"]) or self.estimation_mode != "auto" or self.fallback_policy != "deny" or bool(self.estimator_config) + or any(bool(controls) for controls in self.role_estimator_controls.values()) )🤖 Prompt for AI Agents

In `@python/aisimulate/src/aisimulate/runner.py`:
- Around line 1172-1177: Update the AIC timing configuration handling in
EngineReplayRunner.run before the topology alias loop: read timing_model.config
without a default, validate that it is a mapping, and raise ValueError with the
specified message when it is not. Do not coerce invalid or null configuration to
an empty mapping.
In `@python/aisimulate/src/aisimulate/sweeper/config.py`:
- Around line 746-747: Split the validation in the role_estimator_controls loop:
have the role membership check raise a message identifying the unsupported role
and valid role names, then compute unknown control keys and raise the existing
control-specific error only when that list is nonempty.
- Around line 763-779: Update SearchSpace validation in
_validate_estimator_controls to reject non-empty role_estimator_controls when
deployment_mode includes “afd” or “afd+pd”, raising the documented ValueError
before evaluating nondefault controls. Ensure these unsupported controls are not
propagated through AFD preflight while preserving validation for regular
language-worker modes.
In `@python/aisimulate/src/aisimulate/sweeper/kv_load.py`:

What this PR does
This PR consolidates Rust, Python, CLI, Sweeper, recommendation, and replay estimator construction behind one typed ForwardPassPerfModelConfig contract. The incremental head merges current main, preserving main's manual exact-SHA staging workflow while retaining a scheduled-publication gate for the outstanding Dynamo migration and incorporating main's performance-grid indexing work.
The merge resolution thoughtfully keeps manual staging distinct from scheduled publication, adds focused workflow-contract coverage for that distinction, and documents why the standalone AIC compatibility distributions are a separate package lineage.
Why this score
The exact-head score is 6.4/10 with REQUEST_CHANGES. The main merge and its release-workflow resolutions pass targeted checks, but the prior P1 DSV4 readiness defect is unchanged: construction still treats the required phase module table and paged-MQA auxiliary table as alternatives, so auto selection can pin op_level and fail on its first query. Exact-head CodeRabbit also opened eight current actionable threads; those existing comments are not duplicated. The requested Fable model was not observed, so this is a verified Codex result with unavailable dual-review consensus.

Suggestion for We could rename 4.6 to Select and configure performance estimators and organize it into:
Keep quantization/kernel selectors, exact cached-prefix counts, and speculative decoding in 5.6, with a link back to 4.6 for supported controls. Keep the per-operation source-diagnostic limitation explicit. While making this move, please also correct 4.6's statement that |

Addressed the migration-guide reorganization in 1b1aba29. Section 4.6 is now “Select and configure performance estimators”: 4.6.1 covers selection, the FPM example, auto priority, deny/allow, cold regression, and legacy migration; 4.6.2 covers data/transfer policies, custom roots, and estimator tuning. The example uses Section 5.6 retains the compatibility/SDK-only quantization/kernel selectors, exact cached-prefix assumptions, and speculative decoding, with a link back to 4.6. Per-operation source diagnostics remain explicitly limited to the compatibility CLI/SDK. Both old 4.6 anchors and main's new fixed-prefix clarification are preserved. Local documentation destinations pass validation. |

Approving cf0c64fa123c0ba48d5ec950f3b87c1974b8bf45 with the non-blocking follow-ups below. The four originally posted reproductions now pass against the rebuilt native runtime. Broader verification passed 2,576 tests, with 5 declared cross-repository Dynamo skips and 1 ignored Rust test.
After checking exposure, defaults, and workarounds, I do not consider the three additional cases below merge-blocking. They are reproducible defects; the assessment is that their bounded impact permits follow-up. The mixed-AFD issue should be treated as P2 rather than the provisional P1 classification because it requires an experimental SDK-only combination plus an explicit legacy selector. This approval supersedes my earlier request for changes.
Non-blocking follow-ups
-
P2 — MoE communication readiness with incomplete custom roots. At readiness.rs:261,
MoeDispatchaccepts any communication family even when the topology requires a particular family. The failing fixture deliberately omits NCCL/OneCCL while retaining custom-allreduce and a matching synthetic FPM dataset: auto chooses op-level and fails on its first query, while explicit interpolation returns 4.5 ms. The identical Qwen3-30B-A3B/B200/vLLM 0.24.0/TP1/attention-DP2/MoE-EP2 configuration with the shipped data succeeds. Follow-up: validate the communication family required by backend/topology. This is an additional edge case of F1; the original absent-GEMM reproduction is fixed. Workaround for partial datasets: select the available FPM estimator explicitly or provide the required communication data. -
P2 — Explicit FPM selection in mixed AFD SDK searches. At config.py:574, any AFD mode suppresses legacy-selector migration for the whole search. A
SmartSearchConfigwithdeployment_mode: [agg, afd]andagg_forward_model: fpmcan therefore run the aggregated candidate withauto/op_level. The public recommendation configuration rejects mixed AFD modes, and AFD is documented as experimental. Follow-up: preserve ordinary-branch selectors when AFD branches coexist. Workaround: run AFD and ordinary searches separately. This still deserves attention because the affected SDK path silently changes estimator choice. -
P2 — Encoder recommendation with explicit backend-version maps. The new mapping type reaches encoder lookup as a dictionary rather than the selected backend's version. Public recommendation for Qwen3-VL-8B-Instruct/H200/SGLang fails with
backend_version: {sglang: "0.5.14"}. Both scalar"0.5.14"and an omitted version succeed: one feasible candidate, one completed request, 15.285788 ms. An explicit encoder version also works in a single-backend search. This is a supported, plausible user configuration rather than a synthetic-only case, but it fails visibly and has workarounds. Follow-up: resolve the map per backend before encoder lookup. For multi-backend searches needing exact pins, split into single-backend searches until fixed; omitting pins does not preserve exact-version intent.
These checks establish the trigger conditions and working controls; they do not establish production usage frequency. Full CI, applicable CODEOWNER approvals, and the documented Dynamo migration/release gate remain separate requirements. This is code-review approval, not a waiver of those gates.

Summary
Performance-model construction now uses one Rust-owned
ForwardPassPerfModel::best_available(config)contract, exposed to Python and used by regular CLI, Sweeper, and Replay workers. This continues #13 and preserves the complete resolved identity through recommendation, saved configuration, capacity sizing, and native replay.worker_type; defaultestimation_mode: autoandfallback_policy: deny. Auto searchesop_level -> fpm_interpolation -> fpm_regressioneven with deny. Explicit modes with deny stay strict; allow tries the requested mode followed by the remaining global priority. Queries do not switch estimators.estimator_configcarries regression/correction bucket controls, feature weights, regularization, and correction bounds. Rust owns validation/defaults. Shared correction remains deferred; existing correction and role-bound regression behavior is preserved.auto + deny, and preserves old anchors. Repository AI guidance requires every new performance-model feature to extend this canonical interface, including compatibility CLI callers.speculationidentity, carried through CLI/Sweeper/native replay and saved configurations. Rust validates supported backend, depth, and estimator combinations; acceptance/progress remain in Replay. FPM accuracy adapters use the canonical constructor for current wheels while retaining compatibility for evaluating older branch wheels.de21b8285aefc7ea3b50ec8525051088a87d3081. Both scheduled and approved manual publication require clear migration declarations at the resolved publication target as well as the workflow revision; the trusted checker runs from the workflow revision. Main's SGLang static KV correction, ngram CLI, Replay reporting/lifecycle changes, pool cleanup, and FPM accuracy page are preserved.Validation

No golden changes.Integration boundaries
Native construction still uses the existing Python model compiler. A fully native Rust compiler and shared correction are follow-ups. Offline simulation rejects untrained regression. AFD, analytical encoders, and fixed/polynomial timing retain their existing providers; regular default timing roles use the canonical constructor.
Dynamo #14065 must migrate and pass Planner/wheel validation before release.
.github/release-gates.jsonand the scheduled/manual nightly checks block publication until the migration is cleared in a reviewed change. Missing or malformed target gate declarations also block publication. The separate standalone AIC 0.12 distributions build their own native core and do not consume the new AISimulate wheel/crate. Companion integration and full CI remain merge prerequisites.Linear: https://linear.app/nvidia/issue/AIC-1770
