What does this PR do?

Puzzletron setup requires interactive answers, so automated jobs cannot create a campaign from defaults alone. Generated campaigns can then fail or vary across machines because launch settings and failures are not propagated consistently, profiling relies on implicit trust and network access, checkpoints can appear complete too early, and CI does not verify installed source revisions. This PR fixes that full unattended path.

Type of change: New feature

The setup change adds --non-interactive, reads required values from the supplied defaults, and reports missing or invalid input immediately. Interactive setup remains unchanged.

The remaining changes fix problems in the workflow launched by that setup:

  1. Distributed workers receive the correct GPU assignment, task identity, and multi-node connection settings. Worker, cleanup, and finalization failures are returned to the controller.
  2. AIPerf requires explicit permission to load remote model code or resolve tokenizers online.
  3. Distillation checkpoints are marked complete only after their saved configuration has been refreshed. Save failures are reported to every rank.
  4. CI verifies the installed package versions and source revisions used by Puzzletron before running tests.

Testing

Focused CPU tests covered non-interactive setup and the supporting worker, profiling, checkpoint, and environment changes. GPU lifecycle testing was not run.

Summary by CodeRabbit

📝 Walkthrough

Walkthrough

Puzzletron adds non-interactive setup profiles, CI dependency provenance checks, explicit AIPerf security policies, revised distributed orchestration, and stronger distillation and evaluation validation.

Changes

Puzzletron setup and environment verification

Layer / File(s) Summary
Non-interactive setup workflow
puzzletron_setup/v2/*, puzzletron_setup/bundle.py, examples/puzzletron/README.md, CHANGELOG.rst, tests/unit/torch/puzzletron/test_setup_v2_quick.py, tests/unit/torch/puzzletron/test_setup_bundle.py
The CLI accepts campaign directories, setup profiles, and non-interactive execution. Prompt defaults produce values or raise SetupError. Wizard validation and bundle rendering support the new flow.
Version and VCS verification
examples/puzzletron/ci_environment.*, examples/puzzletron/ci_environment.json, noxfile.py, tests/unit/torch/puzzletron/test_ci_environment.py
The Nox session checks pinned base versions and exact repository and commit metadata for lmms-eval and nemo-automodel. Dirty editable checkouts and mismatched sources are rejected.

AIPerf security-policy propagation

Layer / File(s) Summary
Remote-code and tokenizer policies
modelopt/torch/puzzletron/security_policy.py, modelopt/torch/puzzletron/benchmarks/aiperf.py, modelopt/torch/puzzletron/post_mip/runner.py, modelopt/torch/puzzletron/stages/future.py, modelopt/torch/puzzletron/utils/vllm_adapter.py, examples/puzzletron/run_profile_aiperf_worker.py, related tests
Remote model code and AIPerf v0.11 online tokenizer resolution are disabled by default. Validated options reach vLLM and AIPerf subprocesses and affect cache identities. Policy-owned vLLM arguments cannot be overridden.

Distributed orchestration and aggregation

Layer / File(s) Summary
Rendezvous, topology, and aggregation
modelopt/torch/puzzletron/orchestration/*, examples/puzzletron/distributed_eval/*, tests/unit/torch/puzzletron/test_orchestration_*.py
Rendezvous selection is centralized. Group rank zero owns pool control. Worker commands consume launcher metadata, derive process counts from allocation topology, and use LocalExecutor for local aggregation. Task launchers return payload exit statuses.

Distillation and scoring validation

Layer / File(s) Summary
Checkpoint publication and runtime contracts
modelopt/torch/puzzletron/distillation/global_kd_recipe.py, modelopt/torch/puzzletron/distributed_eval/automodel_executor.py, tests/unit/torch/puzzletron/test_global_kd_canonical.py, tests/unit/torch/puzzletron/test_automodel_solution_scoring.py
Checkpoint publication refreshes realized configuration before creating completion markers and broadcasts failures across ranks. Evaluation validates setup state, rank observations, device consistency, and candidate LM-head availability.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to e39e1

Distillation checkpoints may be marked complete before required configuration updates are saved for nested text-model blocks, which can lead to incomplete or incorrectly resumable checkpoints. Merge should wait for this bounded correctness issue to be fixed or explicitly accepted.

Full details: Security Anti-Patterns

Explanation

No custom-check failure was introduced. The scoped PR diff adds no torch.load(..., weights_only=False), numpy.load(..., allow_pickle=True), hardcoded trust_remote_code=True, external-input eval/exec, or # nosec lines. The changed vLLM adapter replaces its prior hardcoded trust with trust_remote_code=False by default, and AIPerf validates and forwards the caller policy. Existing hardcoded trust and # nosec instances are unchanged. No dependency declaration files changed.

Re-export require_boolean_policy from the Puzzletron package.

security_policy.py declares require_boolean_policy as public, but modelopt/torch/puzzletron/__init__.py does not re-export it. Add from .security_policy import *, or remove it from __all__ if it is private.

Inline comments:
In `@modelopt/torch/puzzletron/distillation/global_kd_recipe.py`:
- Around line 671-687: The checkpoint finalization logic should detect block
configurations both at the top level and under text_config before touching
saving_completed. Update the config check around
refresh_realized_checkpoint_config to trigger for either location, preserving
the existing trust_remote_code handling, and add a regression test covering a
checkpoint with nested text_config.block_configs.

In `@modelopt/torch/puzzletron/orchestration/adapters/sharded.py`:
- Line 157: Update the local aggregation path around LocalExecutor to construct
it with plan.runner, ensuring the configured runner contract is used for setup
and execution. Adjust the local-aggregation test to verify LocalExecutor
receives runner.

In `@puzzletron_setup/v2/wizard.py`:
- Around line 4507-4520: Update the campaign_dir handling around
get_setup_preset and WizardState.start so setup_profile is validated before the
full branch returns. For full setup, pass the validated profile into
WizardState.start if supported; otherwise explicitly reject a supplied profile
with full mode, while preserving quick setup behavior.

In `@tests/unit/torch/puzzletron/test_automodel_solution_scoring.py`:
- Around line 318-323: Move the AutoModelReplaceBlockExecutor and distributed
imports used by test_rpc_executor_non_output_pipeline_rank_reaches_collective to
module scope; if either must remain lazy because of an optional dependency or
circular import, add a brief comment naming and justifying that dependency.

In `@tests/unit/torch/puzzletron/test_global_kd_canonical.py`:
- Around line 790-852: Extend
test_global_kd_checkpoint_publication_failure_reaches_all_ranks with a parent
save_checkpoint failure scenario: make BaseRecipe.save_checkpoint raise on rank
zero, then verify _WeightedObjectiveMixin.save_checkpoint propagates the
original error on rank zero and broadcasts an error so the non-main rank also
raises instead of blocking. Keep assertions focused on the collective count and
rank-specific error behavior, and preserve the existing publication-refresh
failure coverage.

In `@tests/unit/torch/puzzletron/test_profile_aiperf_worker.py`:
- Around line 143-182: Move the standard and project imports currently inside
test functions, including sys, worker_module, json, run_worker, and benchmarks,
to module scope in the test module. Retain any local import only if it is
required for a circular dependency or optional dependency, and document that
reason with a nearby comment.
- Around line 175-218: Update
test_profile_aiperf_worker_forwards_security_policy_to_real_sweep to
parameterize trust_remote_code and allow_aiperf_v011_online_tokenizer_resolution
as independent boolean values, including both (True, False) and (False, True)
combinations. Pass each parameter to run_worker separately and assert each
forwarded keyword against its corresponding value.

Refresh nested text_config.block_configs before publishing completion.

Line 674 checks only top-level block_configs. This module also supports block configurations under text_config at Lines 124-127. A nested configuration skips refresh_realized_checkpoint_config() and still creates saving_completed, so a consumer can accept a checkpoint without refreshed AnyModel interchange metadata.

Check both locations before creating the marker. Add a regression test for a nested text_config.block_configs checkpoint.
