Prerequisites
- post training
Learning sequence
- Frontier-ceiling validation
- Frozen baselines and heldouts
- Slice and safety gates

- Packaging and report cards
- Ship, route, retry, or reject
Hands-on lab
Audit Needle, Chess, and 2048 and explain how the ruler or safety gate changed the decision before integration or training.
Mastery gate
Reject a superficially good score when its frontier ruler, safety slice, breadth gate, or provenance is invalid.

How to read this dossier
This canonical page separates the retained repository decision from the material that informed it. A source may describe an external claim, historical measurement, local observation, or planned procedure; those evidence classes are not interchangeable. Follow the provenance links before reusing a number or method.
Status and disposition describe what PostTrainLLM retained when this record was indexed. They are not a live product promise, a newly run benchmark, or permission to restart historical work. Unknown or unmeasured fields remain unknown rather than being treated as zero.
To reuse the record, first name the exact claim you need and trace it to the linked source. Then check whether the original environment, model revision, data split, evaluator, hardware, and budget match the proposed use. If they do not, treat the record as a hypothesis or design reference and run the smallest fresh comparison that can falsify it. Preserve negative outcomes and regressions beside any improvement; a local win on one slice does not silently become a general capability claim.
Source provenance
The normalized record comes from docs/learn/path-registry.json. The links below are the tracked evidence and explanatory sources preserved with the record.
