Target
Diagnose a measured model failure without treating a visualization as causal proof.
Failure this recipe addresses
Aggregate scores cannot explain which layers, tokens, or representations drive a failure.
Data contract
A frozen set of successful and failed traces from one checkpoint.
Method or policy
Use logit lens, probes, activation patching, causal tracing, or SAE analysis with an explicit hypothesis.
Evaluation contract
Prediction change under a controlled intervention, not visual salience alone.
- control prompts
- random intervention
- layer/token stability
- replayability
Budget and stop rule
Closed as a learning/reference lane; future use must be attached to a specific model failure.
Stop if the probe has no discriminating prediction or intervention control.
Decision rule
Use findings only to change a recipe when a controlled intervention supports them.
Learning exercise
Inspect one logit-lens or activation-patching fixture and write the causal claim it does and does not support.
Separate correlation, localization, and causal intervention.
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.
