 "title": "Turn a model failure into a reproducible handwriting batch",
 "page_title": "How to turn a model failure into a reproducible handwriting batch with Veri Ink",
 "summary": "Trace a failed case to its seed and generation record, then regenerate a matching batch.",
 "who": "An ML engineer whose OCR or multimodal grader just failed on a specific handwriting pattern and needs more data like it.",
 "problem": "A failure is hard to reproduce or expand into training data when the generation details were never recorded.",
 "outcome": "A clear view of the seed, labels, bounds, and hash for the failing case, plus a regenerated batch built from the same rules.",
 "steps": [
  "Run `git clone https://github.com/znxzsy/VeriInk.git` and then `cd VeriInk`.",
  "Read the architecture and data boundary notes in the docs/ folder.",
  "Open src/veriink/ and locate the deterministic renderer and the validation code.",
  "Run `python scripts/generate_demo.py` to rebuild the gallery and its manifests.",
  "Open examples/gallery/manifest.json and check the seed, labels, bounds, and SHA256 for the record that matches your failure pattern."
 ],
 "agent_prompt": "In the VeriInk repo, read docs/ and src/veriink/, then open examples/gallery/manifest.json. For the failure pattern <failure-pattern>, list the matching records with their seed, labels, bounds, and SHA256. Verify that each listed seed, when used for rendering, is covered by the existing validation checks.",
 "agents": [
  "any"
 ],
 "difficulty": "Advanced",
 "time": "30 minutes",
 "basis": "readme",
 "caveat": "The README does not document how to write a task specification from a failure, so you will need to read the source to map your own failure into the renderer.",
