SchemaProof 0.1.0

SchemaProof 0.1.0

SchemaProof proves whether a database migration is compatible with the application versions that coexist during deployment.

Highlights

• Deterministic old/new application × old/new schema compatibility matrix.
• migration-first, app-first, and rollback-safe deployment policies.
• Isolated Git worktrees and temporary SQLite databases.
• Terminal, JSON, and responsive HTML reports.
• Installable Codex plugin with the $schema-proof repair workflow.
• Unsafe rename and expand-and-contract demonstration fixtures.
• Zero external runtime dependencies.

Try it

git clone https://github.com/terrizoaguimor/schema-proof.git
cd schema-proof
npm test
npm run demo

Requires Git and Node.js 22.13 or newer.

MVP boundary

Version 0.1.0 uses SQLite fixtures and trusted local repository commands. It does not connect to production databases.
