In `@modelopt/torch/puzzletron/evaluation/lmms.py`:
- Line 741: Update _evaluation_progress_payload so the top-level current and
total represent cumulative progress across all progress_tasks, including
completed prior-task samples; keep the active task’s local current and total
under task. Ensure the payload matches _task_progress’s configured aggregate
values so progress.py and dashboard.py preserve continuity across task
boundaries.
- Line 876: Update the timeout-handling path around asyncio.gather(*pumps) to
bound how long pump tasks are awaited, ensuring inherited pipe writers cannot
block indefinitely and LmmsEvalTimeoutError is raised promptly. Preserve normal
pump cleanup while applying the timeout specifically to the timeout path.
In `@modelopt/torch/puzzletron/post_mip/reporting.py`:
- Around line 347-357: Update the teacher-observation handling around
teacher_signatures.add so rows with no reference metrics are skipped before
creating a teacher signature; only add a signature and teacher row when at least
one reference value is non-None, while preserving existing handling for valid
reference measurements and errors.
In `@modelopt/torch/puzzletron/tools/validation_utils.py`:
- Around line 48-58: Extend the shared score-artifact contract so write_results
persists a canonical fingerprint for each candidate, and update
scoring_result_matches to accept the current candidate and compare that
fingerprint alongside resolved scoring arguments. Pass the candidate through
find_missing_solutions, _load_solution_work, and the parent-sweep candidate
check, while keeping parent.json validation on its separate parent-artifact
identity path. Add coverage for unchanged arguments with changed candidate
content in both normal and parent-sweep reuse.

In `@modelopt/torch/puzzletron/evaluation/lmms.py`:
- Line 897: Update the normal-exit cleanup around process.wait() and
asyncio.gather(*pumps) to use the same bounded pump cleanup as the timeout path,
preventing detached descendants from blocking completion after successful parent
exit. Add a regression test covering a detached descendant that keeps stdout or
stderr open.

- Line 229: Update build_post_mip_report_payloads() to validate that
architectures[architecture_id] is a mapping before accessing origins. For
non-mapping records, either treat them as invalid and skip them or raise a
controlled validation error; preserve normal origins iteration for valid mapping
records.

- Around line 167-169: Update the test around apply_runtime_candidate to invoke
one valid forward pass on gdn using the installed compact path, assert that the
result has the expected output shape, and only then call handle.remove().

What does this PR do?
Type of change: Bug fix
Puzzletron's documented first-run flow could fail or become difficult to diagnose because setup inferred incomplete model dimensions, generated inconsistent runtime settings, reused stale scoring outputs, and hid evaluator progress. This change makes the maintained VLM lifecycle smoke the primary onboarding path and hardens the setup, execution, resume, and reporting behavior it exercises.
Usage
Follow the Start here lifecycle smoke in the Puzzletron README. Re-running the same launch command resumes the recorded campaign.
Testing
The focused Puzzletron suite passed 286 tests in the reviewed worker environment. The exact base-to-head test audit reviewed all 15 touched test files in full, removed redundant assertions and helpers, and passed 239 tests. This includes native AutoModel compact execution through the valid no-bias GDN path and bounded cleanup when a descendant holds evaluator pipes open. Formatting, lint, license, security, and targeted mypy checks passed. The longer campaign uses the same workflow and takes longer than the smoke; duration depends on worker hardware, scheduler availability, cache state, and execution profile.
