Why and what changed

Follow-up to my comment on Oct 28 — I went ahead and put this up as a ready offer for the next release rather than wait on a reply, so feel free to request changes or take it in a different direction. The two call sites named in the issue (sdk/picking.py and legacy_cli/utils.py) are already clean on current main, but sdk/pareto_analysis.py still passes inplace=True to DataFrame.drop in two places, and on pandas 3.1 those emit the PDEP-8 Pandas4Warning that breaks Dynamo's profiler tests under warnings-as-errors. This switches both to plain reassignment (df = df.drop(...)), the fix shape suggested in the issue. The replace(..., inplace=True) call in the same module is a different method that doesn't warn on 3.1, so I deliberately left it alone — it's not part of the ask.

Once this ships, the pytest ignores on the Dynamo side can come off: ai-dynamo/dynamo#17161 and ai-dynamo/dynamo#17211 (the backport attempt ai-dynamo/dynamo#17162 was closed without merging).

Summary

Risk: Medium. The diff changes 13 files (+146/-65). Only two lines change Python behavior, in sdk/pareto_analysis.py. The rest changes CI runner labels, container HOME values, and adds a new workflow. Three areas need human attention:

1. CI runner and HOME changes. Eleven workflows change runner labels from prod-aisimulate-default-* to prod-aisim-default-*. Containerized jobs change HOME from ${{ github.workspace }} to /__w/aisim/aisim. .github/actionlint.yaml declares the new labels and adds dynamo-cpu-4gi-amd64. A new runner-canary.yml (+80 lines) probes these runners. Reviewers should confirm that the new runner labels exist and that the canary passes on them. This summary did not verify runner availability.
2. Issue scope mismatch. Issue #570 names sdk/picking.py:408 and legacy_cli/utils.py:81. This diff does not change either file. The author reports both are already clean on main. The earlier search at HEAD found no inplace drop calls in sdk/ or legacy_cli/. The one remaining inplace use is replace(..., inplace=True) at pareto_analysis.py:588. The author says it does not emit the pandas 3.1 warning. This was not verified. Reviewers should confirm that the Dynamo failures do not come from another call site.
3. Test and CI evidence. The author reports that pytest tests/unit/sdk/picking tests/unit/sdk/test_agg_pareto_system_spec.py -W error::DeprecationWarning passes (29 tests, Python 3.13, pandas 3.1.0). The same run fails on unpatched main with warnings at pareto_analysis.py:622 and :806. This summary did not run tests. Fast and full CI were pending. No completed check results for the current head were supplied.

Changed behavior

Python (1 file, +2/-2):

• _get_best_configs_under_constraint (about line 622): the in-place drop becomes candidate_configs = candidate_configs.drop(columns=["_sla_exceeded"]). A missing column still raises KeyError.
• get_best_configs_for_target_load (about line 806): the in-place drop becomes candidates = candidates.drop(columns=["_sla_exceeded"], errors="ignore"). A missing column is still tolerated.
• Return values and public signatures do not change.

Workflows and config (12 files):

• Runner labels change to prod-aisim-default-* in the listed jobs.
• Containerized jobs set HOME to /__w/aisim/aisim.
• runner-canary.yml is new. It runs manually or on pushes to pull-request/* branches that modify it. It runs only in ai-dynamo/aisim. It checks the commit, workspace, architecture, and writable home. On amd64 and arm64 it also checks writable /scratch when configured.

No exported or public declarations change.

Merge readiness

The Python change appears behavior-preserving from the diff. The workflow changes depend on runner availability, which is not verified. CI is pending. The bot review's "Low" effort estimate is not an approval.

Existing GitHub Actions jobs switch to updated runner labels and fixed container HOME paths. A new runner canary workflow checks runner environments. Two configuration-ranking helpers assign the result of dropping _sla_exceeded.

Changes: Runner configuration and checks

Layer / File(s)	Summary
Update existing workflow runners .github/actionlint.yaml, .github/workflows/*	Existing jobs use updated runner labels. Affected container jobs set HOME to /__w/aisim/aisim.
Add runner canary checks .github/workflows/runner-canary.yml	The new workflow checks checkout identity, workspace and HOME paths, architecture, and write access across configured runners.

Configuration ranking

Layer / File(s)	Summary
Assign DataFrame drop results python/aisim/src/aisim/sdk/pareto_analysis.py	Both helpers assign the result of dropping _sla_exceeded. The target-load helper still ignores the column if it is absent.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: Low · up to ff1ac

The pandas drop cleanup is safe and fixes the warning. The PR also renames CI runner labels and fixes the container HOME path across many workflows, which its description does not mention. Confirm that the new runner pools exist and can run jobs for this repository, ideally with a green runner canary run, before merging.

Full details: Title check

Explanation

The title names the behavioral change (stop passing inplace to DataFrame.drop) and the warning it addresses (Pandas4Warning on pandas 3.1). It matches the changeset, which replaces two inplace=True drop calls in sdk/pareto_analysis.py with reassignment. The title is specific and uses no vague terms. It uses a fix(sdk) prefix, and no title format rule was configured beyond the stated precision requirement.

Full details: Description check

Explanation

The description follows the repository template. It covers Why and what changed, a Review map with risk level, start-with file, contract status, and compatibility notes, Evidence with test commands and results, and Tracking with a closing keyword for #570. Modeling or data provenance is marked N/A. Evidence lists CodeRabbit reviewed commit as pending, which is expected before review. The template's comment says the commit should be identified when evidence comes from CI. Fast and full CI are pending, so the tested commit is not yet identified. The Review map names python/aisimulate/src/aisimulate/sdk/pareto_analysis.py, but the raw summary lists the file as python/aisim/src/aisim/sdk/pareto_analysis.py. This path mismatch should be checked.

Resolution

Confirm the file path in the Review map (aisimulate vs. aisim) matches the diff. Identify the tested commit once CI completes, and fill in the CodeRabbit reviewed commit field when available.

Full details: Linked Issues check

Explanation

Issue #570 requires that DataFrame.drop(inplace=...) calls stop emitting Pandas4Warning on pandas 3.1, using assignment. The commit range from merge base 570eed2 to head ff1ac42 includes the earlier pareto change from 86e53d0. In python/aisim/src/aisim/sdk/pareto_analysis.py, _get_best_configs_under_constraint now uses candidate_configs = candidate_configs.drop(columns=["_sla_exceeded"]), and get_best_configs_for_target_load now uses candidates = candidates.drop(columns=["_sla_exceeded"], errors="ignore"). The issue-named legacy_cli/utils.py had no inplace drop at the prior review. The PR reports that the sdk/picking path passes under -W error::DeprecationWarning on pandas 3.1.0. The newer commit ff1ac42 changes CI workflow files only, so it does not change this conclusion. Path note: the issue and PR use aisimulate/..., but the tree uses python/aisim/src/aisim/...; files were mapped by name. The PR reports test results from its own run; these were not re-executed here.

Full details: Modeling And Data Evidence

Explanation

The check applies to changes in formulas, selection logic, model or performance data, or predicted outputs. The code diff in python/aisim/src/aisim/sdk/pareto_analysis.py changes two lines (619-622 and 803-806). Each replaces DataFrame.drop(..., inplace=True) with reassignment. The diff does not change any formula, filter, sort, or threshold. The rest of the PR is CI runner and HOME configuration in .github/ files, which is outside this check's scope. The change is still in a selection module (_get_best_configs_under_constraint, get_best_configs_for_target_load). Even so, the PR supplies the evidence the check asks for: - Provenance: the author states the change is a mechanical refactor with identical output. - Reproducible before/after evidence: the pytest command -W error::DeprecationWarning passes 29 tests on the patch and fails on unpatched main (77ee9fc) with Pandas4Warning at pareto_analysis.py:622 and :806. The author also reports the warning count going from 4 to 0. - Output comparison: the author reports byte-identical DataFrames across the under-constraint, fallback, and all-SLA-exceeded paths. Limitation: the byte-identical comparison is asserted in the PR text. The driver script and its output are not attached. This does not change the verdict, because the diff itself is a pure refactor with no model, data, or predicted-output change. The check's failure conditions (unexplained refresh, binary-only validation) do not apply.

Full details: Compatibility Boundaries

Explanation

The PR changes two lines in python/aisim/src/aisim/sdk/pareto_analysis.py, which replace DataFrame.drop(..., inplace=True) with reassignment. Outputs are unchanged, and no public signature changes. Against the checks: - Public surfaces, schemas, versions, bindings, defaults: No change. The diff touches no pyproject.toml, Cargo.toml, version field, binding, schema, or documented default. - Standalone from Dynamo: The PR adds no Dynamo import or package dependency. The new dynamo-cpu-4gi-amd64 label (in .github/actionlint.yaml and runner-canary.yml) is a CI runner-pool name, not a build or runtime dependency. Existing Dynamo references in python/aisim/tools/simulation_perf_gate/ were already present and are not changed by this PR. - One-wheel plus one-crate artifact contract: No packaging or build configuration changes. The workflow edits only change runner labels, HOME values, and add a runner canary workflow that does not publish artifacts. Residual note: the shared-runner pool name in CI is a Dynamo-named infrastructure label. It does not affect code, artifacts, or compatibility surfaces, so it does not match a failure condition in this check.

Full details: Review Evidence

Explanation

The PR description meets the Review evidence criteria. - Commands and results: It names the exact local command, pytest tests/unit/sdk/picking tests/unit/sdk/test_agg_pareto_system_spec.py -W error::DeprecationWarning. It reports 29 passed on Python 3.13 / pandas 3.1.0. It also reports the same run failing on unpatched main (77ee9fc) with Pandas4Warning at pareto_analysis.py:622 and :806. - Negative and boundary validation: It covers the under-constraint, fallback, and all-SLA-exceeded (errors="ignore") paths. It reports byte-identical DataFrames before and after, and warnings going from 4 to 0. This is proportionate to a two-line, low-risk change. - Evidence type: The test result is labeled as local. Fast CI and Full CI are explicitly marked "pending on this PR", so no hosted CI result is claimed. The description makes no fake-runner, parity, or production claim, so no evidence category is conflated. - Inactive nested workflows: The description does not cite any workflow, including the new runner-canary workflow, as CI evidence. The fail condition does not apply. Gap, outside the stated criteria: the description does not mention the second commit (ci: switch workflows to renamed AISim runner pools). It also does not say how the runner-pool and HOME changes were validated. The check does not require this, so it does not change the verdict. The description's "Start with" path (python/aisimulate/...) also differs from the summary path (python/aisim/...). This is a documentation detail and does not affect the evidence check.

Full details: Out of Scope Changes check

Explanation

The whole-PR range (merge base 570eed2 to head ff1ac42) includes commit ff1ac42 with subject "ci: switch workflows to renamed AISim runner pools (#861)". The AI-generated raw summary lists changes to about 14 .github files: runner labels changed from prod-aisimulate-default* to prod-aisim-default*, container HOME values changed, actionlint.yaml edited, and a new .github/workflows/runner-canary.yml (+80 lines) added. None of these changes relates to DataFrame.drop or issue #570. The PR description says the change is a two-line diff and does not mention these workflow changes. The incremental diff read failed (changed blobs missing from checkout), so the file list relies on the commit subject and the raw summary, not on a direct diff read. The pareto_analysis.py change (+2/-2) is in scope.

Resolution

Remove the .github workflow, actionlint, and runner-canary changes from this PR, or move them to a separate PR with their own linked issue and description. Then update the PR description to match the remaining diff. If the workflow changes are required for this fix, the PR description must state the connection and the issue must be linked. After the change, re-run this assessment against the new head.

Full details: Cross-Layer Contract

Explanation

Summary: The pandas change is consistent across its consumers. The CI runner change is not. The PR changes workflow selectors and container HOME paths, but the CI documentation still states the opposite, and the PR does not disclose this scope. What passes: - python/aisim/src/aisim/sdk/pareto_analysis.py (commit f20c2f2e vs base 60c5c386) changes two lines. candidate_configs.drop(..., inplace=True) (line 622) and candidates.drop(..., inplace=True, errors="ignore") (line 806) become reassignments. Return values are unchanged. The replace(..., inplace=True) call at line 588 is untouched, as the PR states. The public function get_best_configs_for_target_load keeps its signature and outputs. The consumers of this change are the in-module callers. No schema, serialization, or default changes. What fails: - The diff also changes 12 workflow files and adds .github/workflows/runner-canary.yml. Across .github/workflows/*.yml, runs-on selectors move from prod-aisimulate-default-* to prod-aisim-default-*. Container HOME moves from ${{ github.workspace }} to /__w/aisim/aisim. .github/actionlint.yaml is updated to declare the new labels. - docs/ci/README.md is stale for this change. Line 623 says the dedicated runner selectors "retain the deployed prod-aisimulate-default-amd64-v1 and prod-aisimulate-default-arm64-v1 labels so this PR can validate before the infrastructure cutover." Line 651 says to update workflow selectors "only when matching pools are registered." Line 651 also says to review the job hook's HOME path during the cutover. Line 657 says to run the rename checks "using the deployed prod-aisimulate-* runner labels." The workflows now contradict these instructions. - The PR asserts compatibility without evidence for the CI layer. The PR description says "Public or serialized contract changed: no" and "Start with: pareto_analysis.py — two-line diff." It does not mention the runner-label or HOME changes. The only validation of the new pools is the new runner-canary.yml, and the PR records no run result for it. The PR does not show that prod-aisim-default-* pools are registered. - The new runner-canary.yml has no test evidence in the PR. The canary depends on external runner registration (Velonix #882), which I cannot verify from this repository. Conclusion: the docs layer is stale against the changed CI selector contract, and the PR asserts a narrower scope than its patch. Under the check, this is a stale layer and an unevidenced compatibility claim. Status is FAIL.

Resolution

1. Choose one path for the CI runner change: a. Remove the 12 workflow edits, actionlint.yaml edits, and runner-canary.yml from this PR, and keep only the pareto_analysis.py change. Use a separate PR for the runner migration. b. Keep the runner migration here. Then update docs/ci/README.md (lines 623, 651, 657, and the HOME-path guidance near line 651) so it describes the prod-aisim-default-* labels and the /__w/aisim/aisim HOME path. Remove the "retain prod-aisimulate labels" instruction. Attach evidence that the new pools are registered and that a runner-canary.yml run passed on amd64, arm64, and shared runners. 2. Update the PR description. List every changed file, not only the Python file. State the runner-label and HOME changes as changed CI inputs. Link the Velonix pool-registration evidence. 3. Keep the pareto_analysis.py change as is. It passes this check.

Linked repositories findings

ai-dynamo/dynamo

Version pins that must move together before the fix reaches Dynamo:

• pyproject.toml:17 pins aisimulate==0.13.0.dev202610290000000087 [::ai-dynamo/dynamo::pyproject.toml:17]
• container/deps/requirements.aisimulate.txt:6 pins the same version. Its comment at line 5 says to keep it in sync with the aisimulate-core pins in Cargo.toml and lib/bindings/python/Cargo.toml [::ai-dynamo/dynamo::container/deps/requirements.aisimulate.txt:5-6]
• Cargo.toml:80 pins aisimulate-core = { version = "=0.13.0-dev.202610290000000087" } [::ai-dynamo/dynamo::Cargo.toml:79-80]
• Review implication: this PR does not change Dynamo's behavior until all three pins move to a release that contains the fix. lib/bindings/python/Cargo.toml was referenced by the comment but not read in this research.

Scoped warning suppression:

• pyproject.toml:343 ignores The inplace keyword in DataFrame.drop is deprecated.* with DeprecationWarning for the aisimulate module [::ai-dynamo/dynamo::pyproject.toml:343]
• The comment at pyproject.toml:342 says AISimulate still passes inplace in aisimulate.sdk.pareto_analysis, which picking calls [::ai-dynamo/dynamo::pyproject.toml:342-343]
• Review implication: once a fixed release is pinned, this filter can be removed, as issue #570 asks. The comment at line 342 will be stale after the fix lands.

Downstream aisimulate consumers of the picking module:

• components/src/dynamo/profiler/thorough.py:25 imports pick_load_match from aisimulate.sdk.picking, alongside pick_autoscale and pick_default [::ai-dynamo/dynamo::components/src/dynamo/profiler/thorough.py:25]
• components/src/dynamo/profiler/utils/aic_dataframe.py:27 imports the private helper _build_disagg_summary_dict from aisimulate.sdk.picking [::ai-dynamo/dynamo::components/src/dynamo/profiler/utils/aic_dataframe.py:27]
• Review implication: the PR's byte-identical-output claim matters for these callers. The pick_load_match path is the one the issue names as failing in Dynamo's profiler tests. The thorough.py dispatch lines cited in earlier research were not re-read in this pass.

Other inplace=True usage in Dynamo Python:

• The only other match is tests/fault_tolerance/deploy/legacy_parse_results.py:138, which is df.sort_values("time", inplace=True) [::ai-dynamo/dynamo::tests/fault_tolerance/deploy/legacy_parse_results.py:138]. This is not a drop call, so it is outside the deprecation named in #570.

ai-dynamo/aiconfigurator

This repository is a frozen migration reference, so these lines are for detecting semantic drift rather than runtime use.

• src/aiconfigurator/sdk/pareto_analysis.py:1890 is candidate_configs.drop(columns=["_sla_exceeded"], inplace=True), with no errors argument. A missing column raises here [::ai-dynamo/aiconfigurator::src/aiconfigurator/sdk/pareto_analysis.py:1890]
• src/aiconfigurator/sdk/pareto_analysis.py:2074 is candidates.drop(columns=["_sla_exceeded"], inplace=True, errors="ignore"). A missing column is ignored here [::ai-dynamo/aiconfigurator::src/aiconfigurator/sdk/pareto_analysis.py:2074]
• Review implication: the two drops differ in errors handling. Any AISimulate reassignment must keep each site's semantics. The AISimulate diff was not readable from the linked repos, so this cannot be confirmed.
• src/aiconfigurator/sdk/pareto_analysis.py:1856 is candidate_configs.replace([np.inf, -np.inf], np.nan, inplace=True) [::ai-dynamo/aiconfigurator::src/aiconfigurator/sdk/pareto_analysis.py:1856]. This is not a drop. The PR author's claim that pandas 3.1 does not warn for replace(..., inplace=True) cannot be checked from the repos here.
• Dependency context: pyproject.toml:43 declares aiconfigurator-core==0.12.0, and pyproject.toml:48 declares pandas>=2.2.3 [::ai-dynamo/aiconfigurator::pyproject.toml:43], [::ai-dynamo/aiconfigurator::pyproject.toml:48]. The pandas floor does not exclude pandas 3.1.

Limitations

• ai-dynamo/aisimulate is not among the linked repositories. The PR's diff in sdk/pareto_analysis.py could not be read, so the claims about byte-identical output and the warning count rest on the PR summary.

270-270: Stability & Availability

Whether the renamed prod-aisim-default-* runner pools exist and accept jobs from ai-dynamo/aisim cannot be decided from the supplied evidence. The runner inventory query was denied with HTTP 403. The diff does not show that either label is absent. The concern depends on live runner provisioning and runner-group access, so it stays open until that inventory can be read with sufficient permission.

.github/workflows/prediction-regression-gate.yml: 1

68-68: Stability & Availability

The comment's failure path requires /__w/aisim/aisim to be absent or unwritable on the new collect runner. The inspected repository evidence does not show that. The canary is designed to fail if that path is not the writable HOME, and no canary run has concluded either way. The inspected files also show no CARGO_HOME or RUSTUP_HOME override, and the gate file that would show one was not read. The remaining request to check canary results is a verification step, not evidence of a defect in the change.

9.5/10 · high confidence

The PR replaces two inplace DataFrame.drop calls with reassignment to remove pandas 3.1 deprecation warnings during configuration selection. The new head also carries the AISim CI runner-label and container HOME migration plus a runner canary, matching merged PR #861.

9.5/10; APPROVE. The 12-file incremental delta exactly matches merged #861, the application and test sources are unchanged from the previous reviewed head, and all 26 targeted workflow contract tests pass. Existing workflow changes are limited to runner-label and HOME substitutions; the canary source matches a successful amd64/arm64/shared deployment run. A clean merge preview against captured main leaves only the two pandas cleanup lines. No actionable findings or proposed comments remain. Exact-head Full CI and applicable current-head CODEOWNER approval are still needed for merge readiness.
