Inline comments:
In `@examples/puzzletron/evaluation/vlm/post_mip.py`:
- Around line 97-98: Update the validation error messages in _run_profile for
missing row_manifest_sha256 to use profile-agnostic wording, removing the
hard-coded “344-row campaign” reference while preserving the existing validation
behavior.
In `@examples/puzzletron/evaluation/vlm/preflight.py`:
- Around line 184-186: Update the ValueError message for the --profile-task
validation to also name the supported judge-free-8_690-examples_r1-native
profile, keeping the existing full-data and short-all-native profile names
intact.
- Around line 282-289: Handle an empty rows or indices selection before
constructing quantiles in the preflight flow, so empty shard selections reach
validate_exact_rows_manifest and produce its existing “must select at least one
row” error instead of indexing an empty list. Preserve the current quantile
calculation for non-empty selections.
In `@examples/puzzletron/evaluation/vlm/preparation/benchmark_data.py`:
- Around line 910-912: Set the staging directory’s permissions explicitly after
tempfile.mkdtemp in the preparation flow, before publication via os.replace or
directory exchange, so the published media root is traversable by other UIDs.
Use the intended 0o755 behavior adjusted for umask (or the project’s established
equivalent), while leaving the staging and publication logic unchanged.
- Line 1008: Update the inventory and preparation flow around
_snapshot_inventory_report, _media_marker_is_current, and _prepare to avoid
unconditional full-content hashing when existing markers’ recorded paths, sizes,
mtime_ns, and ctime_ns still match; reuse the cached inventory in that case, and
only perform SHA-256 verification when explicitly requested while preserving
full validation for changed or missing metadata.
- Around line 103-104: Update _path_traverses_symlink to evaluate is_symlink()
for path and every parent without filtering candidates through exists(), so
dangling symlinks are detected while preserving the boolean traversal result.
- Around line 520-541: Update _task_lock so os.close(descriptor) is used only if
os.fdopen fails before transferring ownership; once the descriptor is wrapped,
rely on the stream context manager and do not close the raw descriptor in the
exception handler. Ensure fcntl.flock(..., LOCK_UN) runs in a finally block so
the lock is released when the yield body raises.
In `@examples/puzzletron/evaluation/vlm/profiles/core-3_full_r1-vllm.json`:
- Line 5: Confirm that the backend_profile value in core-3_full_r1 intentionally
pins the full sample set to the Qwen3.5-0.8B snapshot and rejects alternate
checkpoints or settings overrides; preserve this model pin if intentional,
otherwise align it with the sibling sample profiles.
In `@examples/puzzletron/evaluation/vlm/suites.py`:
- Around line 350-351: Validate the per-task selection value before accessing
population_rows in the task evaluation flow: replace the unchecked cast around
entry.get("selection", {}) with an isinstance(selection, dict) guard, matching
_shard_exact_row_task. Ensure non-mapping selections produce the established
validation error rather than raising AttributeError, while preserving the
existing population_rows fallback for valid mappings.
In `@tests/unit/torch/puzzletron/evaluation/test_checkpoint.py`:
- Line 49: Update the regression test around LMMS_EVAL_REVISION to provide
complete valid VCS provenance, including the repository URL matching the valid
provenance used later in the test. Ensure the checkout represents a missing or
modified compatibility patch so the test exercises patch-state validation rather
than malformed provenance rejection.
In `@tests/unit/torch/puzzletron/evaluation/vlm/test_model.py`:
- Around line 119-130: Extend the checkpoint rejection test around
verify_checkpoint to cover derived heterogeneity independently: keep
heterogeneous block_configs, remove or omit text_config.per_layer_config, and
assert the native qwen3_5 backend still raises the existing ValueError. Preserve
the current declared-per-layer-config case as separate coverage.

What does this PR do?
Type of change: new feature
Adds reproducible Qwen 3.5 VLM evaluation profiles by composing a named sample set, model backend, and pinned evaluator revision. Native and vLLM profiles can evaluate the same examples while keeping their different loading and prompt behavior explicit. This is the first part of a multi-part PR stack; later PRs connect these profiles to campaign and baseline workflows.
core-3_24-examples_r1-*evaluates 24 examples across RealWorldQA, MMMU validation, and MVBench for lifecycle smoke checks.core-3_344-examples_r1-*evaluates 344 examples across those three benchmarks, whilecore-3_full_r1-*evaluates their complete datasets.judge-free-8_690-examples_r1-nativeevaluates 690 fixed examples across eight benchmarks without an external judge.--verify-contentrequests full SHA-256 verification.The existing
short-v1,short-native-v1,short-all-native-v1, andfull-v1names remain as temporary compatibility profiles. They preserve their previous rows and backends, continue using the maintained evaluator revision, and emit a deprecation warning. They will be removed after downstream callers migrate to the descriptive profiles.The lmms-eval compatibility patch preserves per-task vLLM output limits, so the worker image must be rebuilt from this revision before using these profiles.
Usage
Testing
Focused VLM, checkpoint, lmms-eval, image-contract, and post-MIP tests passed locally. File-scoped pre-commit checks passed. No GPU evaluation or worker-image build was run.
