Artifact contract

A real lineage where narrow file-operation depth reached 100% while breadth regressed, proving why routing is part of the artifact.

This routed specialist is classified as guided replay. Workload guidance: replay is read-only; reproduction is a budgeted experiment.

Build

Reconstruct the student, teacher trajectories, filtering, and training lineage from retained evidence.

Modify

Change teacher mix or selection slices as a new recipe version, never silently.

Tune

Tune accepted rows, sampling mix, and steps against the same narrow and breadth gates.

Prove

Read target and breadth scores together: 100% narrow depth did not make a general upgrade.

Package

Package as routed-only with an explicit redirect boundary.

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/artifact-journey.json. The links below are the tracked evidence and explanatory sources preserved with the record.
