Add .claude/settings.local.json, .codex, and .humanize/ to
.gitignore as these are local tool configuration/cache files
that should not be tracked.

- Remove self.preprocessor from MMPRTinyDataset to prevent double
  formatting (vlm_hf_data_processor already handles format dispatch)
- Add pylatexenc to pyproject.toml as transitive dependency of mathruler
  (mathruler does not declare it in its own metadata)

- Fix prompt file brace escaping: \boxed{} -> \boxed{{}} so
  str.format() has exactly one replacement placeholder (fixes AC-2/AC-5)
- Add explicit split parameter validation to MMPRTinyDataset with
  ValueError for unsupported splits (fixes AC-1 negative test)
- Regenerate uv.lock with mathruler and pylatexenc entries (fixes AC-6)
- Add unit tests for dataset formatting, split validation, prompt
  file format compatibility, and verl_geo3k_reward (14 tests, all pass)

Add 3 processor smoke tests using a stub NemotronNanoVLV2Processor:
- test_processor_produces_valid_datum_spec: verifies DatumSpec fields
- test_prompted_text_contains_boxed_literal: verifies \boxed{} survives
- test_placeholder_conversion_for_nemotron_processor: verifies <image>
  placeholder and question text in vllm_content

Uses a tiny 1x1 PNG fixture for image resolution. All 17 MMPR tests
pass (11 dataset + 6 reward).

- Stub now captures the exact text arg passed to __call__
- Assert exact equality: vllm_content == "<image>\n" + prompted_question
- Assert exactly one <image> token in output (no duplicates)
- Negative assertion: raw dataset string "<image>\nQuestion" not in output
- Assert captured __call__ text matches expected tokenizer input
- All tests run with -p no:testmon --override-ini='addopts='

Clean up partial state (stale images_dir, parquet, temp dir) before
re-downloading when the ready marker is absent. Prevents shutil.move
from nesting images/images when images_dir already exists from an
interrupted prior attempt.

MMPR-Tiny has 4,192 rows with multiple images (up to 11). The previous
code truncated to images[0], losing visual context for multi-image
questions.

- _load_mmpr_tiny_from_cache: keep all image paths instead of [imgs[0]]
- format_mmpr_tiny_dataset: split question on <image> and <image_N>
  placeholders, interleave image content items with text segments
- Add tests for multi-image and numbered-placeholder formatting
