 ## Intended Use
 
 - Primary use: Ranks likely bug locations inside repository content.
-- Secondary use: retrieval, ranking, planning, or scientific paper tooling inside the broader Repository Library system, depending on the model family.
-- Out of scope: production safety claims, benchmark claims beyond the bundled experiment config, or use outside the model's narrow training objective without task-specific validation.
+- Downstream use: retrieval, ranking, planning, paper understanding, or cross-domain reasoning inside the broader Repository Library system, depending on the model family.
+- Out of scope: production safety claims, benchmark claims beyond the tracked experiment config, or deployment without task-specific validation.
 
 ## Training Data

 ## Limitations
 
-- These model cards reflect the packaged experiment configs and mirrored checkpoint contents, not an independently audited benchmark sheet.
-- Some training datasets are local corpora or exported shards, so reproducibility may require access to the surrounding Repository Library data pipeline.
-- Models in this stack are narrow components of a larger paper-and-repository system and should be validated on downstream tasks before deployment.
+- These cards are generated from tracked experiment metadata and packaged artifacts, not from a separate benchmark report or external audit.
+- Several training sources are pipeline outputs from the Repository Library codebase rather than standalone public datasets.
+- These models are components of a larger research system and should be validated in their target workflow before deployment.
