Synthetic Schema Drift Regression Preview

Three deliberately small, synthetic cases for testing how a schema-change review or regression gate handles common contract changes:

• —a removed required field;
• —a field type change; and
• —a moved nested field.

Every record is fictional and marked synthetic: true. This preview contains no customer data, credentials, production API response, web extraction, or paid-product file.

Contents

schema-drift-preview.jsonl contains one JSON object per case. Each object has a baseline_schema, candidate_schema, expected_result, and a concise rationale. It is designed for local test fixtures, examples, and evaluation scaffolding—not for production compatibility decisions by itself.

Limitations

• —The three cases are illustrative, not a complete schema-drift taxonomy.
• —No real API, dataset, or service is represented.
• —Consumers remain responsible for their own compatibility policy, test coverage, deployment checks, and source-right review.
• —This is not a hosted API, monitoring service, security assurance, or guarantee that all breaking changes will be detected.

Release checklist

This local package is prepared for a future Hugging Face dataset repository. Before publishing: verify the NimbliqueStudio organization, choose a public repository name, upload these exact files without modification, confirm the generated public URL while signed out, record that URL in nimblique-marketing-channels.md, and then log the first promotion in publication-log.csv.
