Why and what changed

  • Daily run 36702706592 passed main but failed release/0.12.0 and release/0.12.1 importing the renamed baseline CLI.
  • Select exactly one wheel-provided CLI/adapter pair, reject ambiguous or incomplete API layouts, and verify bytes and imports before downloading measurements.
  • Record the selected API, adapter, and actual console entry point. Preserve the entry point in public summaries and accept the two supported entry points in publication validation.

Review map

  • Risk level: medium.
  • Start with predictor_module_names, wheel_identity, and predict_point in scripts/run_e2e_accuracy.py; follow provenance through _aic_source and prepare_e2e_accuracy_pages.py.
  • Serialized contract: optional snapshot.aic_source.cli_entry_point; old summaries remain readable. New producer runtime records the API and adapter and rejects mismatched identity.
  • Compatibility: supports both namespace layouts, without masking import failures or changing prediction formulas. An old publisher rejects the new optional field; deploy producer and publisher changes together or revert together.

Evidence

  • Tested commit: de04ef87.
  • python/aisimulate/.venv/bin/python -m pytest -p no:timeout -q tests/test_e2e_accuracy_nightly.py tests/test_e2e_accuracy_overview.py: 245 passed.
  • node --test tests/test_e2e_accuracy_ui.mjs tests/test_e2e_accuracy_workflow.mjs: 52 passed. These are simulated browser/workflow tests, not hosted campaign evidence.
  • Ruff lint/format on all five changed Python files, git diff --check, and python/aisimulate/.venv/bin/python scripts/check_documentation_links.py: passed (77 Markdown files).
  • Boundary tests: two complete API layouts, a second incomplete layout, missing/mismatched adapter, wheel tampering, incorrect baseline provenance, and unknown public entry point. Both layouts exercise predictor API/adapter routing and campaign-to-publication validation.
  • Expected values: routing tests use controlled module fixtures; they check calls and provenance rather than latency estimates.
  • Before/after: old release import fails before prediction in the linked run; new tests demonstrate correct namespace routing. No claim of numerical or full release-campaign validation.
  • Fast CI: passed on prior dd536f5b; refreshed head pending. Full CI and complete release campaigns remain outstanding.
  • CodeRabbit reviewed commit: dd536f5b; fixes pushed for re-review. Codex: local implementation checks on 04505049, no independent review claimed.

Evidence classification

  • Local contract tests: 245 Python cases, including both namespace layouts through campaign generation and publication; static checked-in-summary and browser validation reject unsupported entry points.
  • Simulated execution: 52 JavaScript tests use fake browser/workflow environments. They do not establish runner resources, real wheel execution, or release campaign completion.
  • Source parity: release namespace and adapter-schema inspection only; not numerical prediction parity.
  • Hosted production evidence: the linked pre-change run passed main and failed releases at import. No post-change full release run or before/after numerical campaign is claimed; this review evidence remains outstanding.
  • Exact static commands: python/aisimulate/.venv/bin/ruff check --config python/aisimulate/pyproject.toml scripts/build_pages_site.py tests/test_e2e_accuracy_nightly.py; python/aisimulate/.venv/bin/python scripts/check_documentation_links.py; git diff --check.

Modeling or data provenance

  • No estimator math, measurement dataset, or performance data changed. Baseline identity now reflects the actual namespace: aiconfigurator.main:main for old releases, aisimulate.legacy_cli.entrypoint:main for migrated wheels. Full before/after campaign evidence remains pending.

Linked repositories findings

ai-dynamo/dynamo

  • Dynamo pins aisimulate and registers only canonical aisimulate.* extension points in pyproject.toml:17,120-130. [::ai-dynamo/dynamo::]
  • Namespace tests require the legacy aiconfigurator entry point to resolve to aisimulate.legacy_cli.entrypoint:main (tests/dependencies/test_aisimulate_namespaces.py:148-175), supporting provenance of the actual entry point. [::ai-dynamo/dynamo::]
  • Dynamo consumers use aisimulate.config_adapter and assert adapter API version 3 (components/src/dynamo/router/simulation/provider.py:11-16,192; related tests at components/src/dynamo/router/tests/test_router_sweep_config_provider.py:149). [::ai-dynamo/dynamo::]

ai-dynamo/aiconfigurator

  • The compatibility distribution explicitly packages aiconfigurator.cli* and aiconfigurator.sdk* (pyproject.toml:101-107), matching the legacy layout supported by this PR. [::ai-dynamo/aiconfigurator::]
  • Its documented adapter contract remains aiconfigurator.sdk.config_adapter, with adapt_config and to_cli_estimate_kwargs (docs/config_adapter.md:9-31), so selecting this adapter for legacy wheels is necessary. [::ai-dynamo/aiconfigurator::]
  • Migration documentation identifies AISimulate as the active distribution while preserving established AIC command paths (docs/aisimulate_migration.md:25-45). [::ai-dynamo/aiconfigurator::]

📝 Summary

Risk: Medium. Three areas need human attention:

  1. Confirm wheel inspection selects exactly one supported API and matching adapter, and rejects incomplete or ambiguous layouts.
  2. Confirm wheel byte and import checks run before measurement downloads in the campaign workflow.
  3. Confirm producer and publisher changes are deployed together, then obtain post-change release campaign results.

Changed behavior and public contracts

  • The campaign selects the baseline API and config adapter from the evaluated wheel. It supports the aiconfigurator.* and aisimulate.* layouts.
  • It rejects wheels with neither supported API, both APIs, or a missing matching adapter. It checks installed files against the wheel and verifies imports.
  • The workflow runs wheel_identity after installing the wheel and before downloading measurements.
  • Baseline provenance records the selected API, adapter, and console entry point. The public summary preserves the entry point and accepts either supported value. The field is optional for older summaries.

Technical evidence

  • The author reports that 235 Python tests and 12 workflow JavaScript tests passed. The author also reports passing Ruff lint/format, git diff --check, and the documentation-link check. These results are not independently verified here.
  • Added tests cover both layouts, incomplete or mixed layouts, wheel tampering, dispatch behavior, provenance, and entry-point validation.
  • The author reports a passing campaign on main and failures on release/0.12.0 and release/0.12.1 before predictions began. No post-change release campaign results are supplied.
  • No numerical accuracy or full release-campaign validation is reported. The author reports no changes to estimator math, measurement data, or performance data.

Merge readiness

  • The reported tests support the compatibility change and its regression coverage.
  • Refreshed-head and full CI status, and post-change release campaigns, remain unreported. Release readiness is not established.
  • Current review finding counts are unavailable. Test reports do not constitute review approval.

Walkthrough

The accuracy campaign selects and verifies a baseline API and config adapter from the evaluated wheel. It uses those modules for baseline prediction and records the selected CLI entry point in the public summary.

Changes

E2E accuracy campaign

Layer / File(s) Summary
Select and verify wheel modules
.github/workflows/e2e-accuracy-branch.yml, scripts/run_e2e_accuracy.py, tests/test_e2e_accuracy_nightly.py, docs/ci.md
The campaign selects one supported API and matching adapter from the wheel. Identity checks import and verify those modules, and the workflow prints the wheel identity. Tests cover both layouts and reject missing, mismatched, or ambiguous modules. Documentation describes the selection and check order.
Use selected modules for baseline prediction
scripts/run_e2e_accuracy.py, tests/test_e2e_accuracy_nightly.py
predict_point uses the selected API and adapter to adapt configuration and estimate the baseline. Tests cover dispatch and baseline failure handling.
Validate and publish selected CLI provenance
scripts/build_e2e_accuracy_overview.py, scripts/prepare_e2e_accuracy_pages.py, scripts/build_pages_site.py, tests/test_e2e_accuracy_nightly.py, tests/test_e2e_accuracy_overview.py, tests/test_e2e_accuracy_ui.mjs
The overview validates the CLI entry point against API and adapter metadata. The public contract and site builder accept only the supported entry points, and the UI displays the selected entry point in provenance. Tests cover valid selections, mismatched metadata, and invalid values.

Full details: Modeling And Data Evidence

Explanation

The PR changes predictor selection and therefore the path that produces baseline outputs in predict_point: predictor_module_names now selects one namespace/adapter pair and cli_estimate is imported from that selection. The PR adds provenance (baseline_api, config_adapter, cli_entry_point) and controlled routing tests, but the tests assert imports, calls, and failure status only. They do not provide an explained golden diff, independent oracle, held-out comparison, or machine-readable before/after output summary with anomaly checks. The workflow prints wheel identity only. The author also states that full before/after campaign evidence remains pending.

Resolution

Add reproducible evidence for the changed selection path. Use fixed input points and both supported wheel layouts, run the prior and new routing paths, and record machine-readable baseline_api, config_adapter, cli_entry_point, backend_version, ttft, and tpot results. Compare the results to an independent oracle or reviewed golden values with documented tolerances and anomaly checks for finite positive latencies, point coverage, and unexpected output differences. Include the evidence in the PR or CI artifact; call-only routing tests are not sufficient.

🔀 Multi-repo context ai-dynamo/aiconfigurator, ai-dynamo/dynamo

Linked repositories findings

ai-dynamo/aiconfigurator

  • The 0.12 package contract places the CLI under aiconfigurator.cli and the adapter under aiconfigurator.sdk.config_adapter; the main wheel must include both plus the packaged schema. [::ai-dynamo/aiconfigurator::]
  • The legacy adapter exports adapt_config and to_cli_estimate_kwargs, with schema version aic-estimate-request/1.0.0 and adapter version 1.0.0. This API should not be assumed interchangeable with the newer AISimulate adapter. [::ai-dynamo/aiconfigurator::]
  • The migration guide states that aisimulate==0.12.0 may temporarily retain the migrated aiconfigurator import namespace for one release. Strict mixed-namespace rejection should therefore be checked against the actual supported wheel contents. [::ai-dynamo/aiconfigurator::]

ai-dynamo/dynamo

  • Current Dynamo consumes only canonical aisimulate namespaces and explicitly rejects installed aiconfigurator/aiconfigurator_core payloads; its legacy console command points to aisimulate.legacy_cli.entrypoint:main. [::ai-dynamo/dynamo::]
  • Dynamo’s provider ABI is separate from the legacy AIC adapter: current providers import aisimulate.config_adapter contexts and declare config_adapter_api_version = 3. The E2E script must select the wheel-specific baseline adapter rather than treating these APIs as equivalent. [::ai-dynamo/dynamo::]
  • Dynamo pins an exact AISimulate release and validates its aisimulate entry points and canonical import namespaces in dependency tests, confirming that namespace selection is a release-level compatibility boundary. [::ai-dynamo/dynamo::]

Brings in the FPM decoupling / self-service onboarding stack (ai-dynamo#238, ai-dynamo#248,
ai-dynamo#347), the output adapters (ai-dynamo#334) and the CI changes (ai-dynamo#349, ai-dynamo#351, ai-dynamo#353,
ai-dynamo#354, ai-dynamo#330, ai-dynamo#319).

Conflict resolutions:

- ENGINE_SPEC_SCHEMA_VERSION: upstream claimed 25 for the FPM decoupling
  selector; decode CP is renumbered to 26 (positional dcp_size tails on the
  attention / MLA / DSA ops). Stale-payload loops reject 20..25; the 25
  payload keeps the selector like the decoupling branch's 21.
- cp_size: upstream added a CP1-only `cp_size` to compile_engine,
  estimate_kv_cache / estimate_num_gpu_blocks, EngineBuildRequest and the
  legacy Rust compile path ("this SDK entry point does not support context
  parallelism"). This branch supports prefill CP at exactly those entry
  points, so the duplicate parameters / struct field are folded into ours,
  the CP1 gates become positive-integer validation, and the FPM profile cell
  selection receives the real cp_size (a profile without that cell fails
  loud with "no matching FPM deployment profile"). Upstream's tests are
  adjusted accordingly.
- FpmCompileConfig / AicTimingConfig parallel-shape checks combine
  upstream's `fpm_profile.is_none()` exemption with the `* cp_size` fold;
  aic_capacity_kwargs gains cp_size / dcp_size; fpm best_available keeps
  upstream's registered-architecture check ahead of the DCP mode gate.
- capacity.py worker resolution carries aic_cp_size / aic_dcp_size next to
  aic_fpm_profile / worker_type.
- ParallelismPresetConfig.prefill_context becomes Optional (None = 1), like
  decode_context, so default parallelism dumps carry no CP keys; the new
  onboarding topology tests (ai-dynamo#248) compare those dumps against the
  six-key request parallelism. Consumers read it through compiler._prefill_cp.
