Gate 3: Technical architecture document - defines HOW/WHERE with technology-agnostic patterns before concrete implementation choices.
Convex development guidelines and best practices. Use when writing Convex functions, queries, mutations, schemas, or reviewing Convex code. Triggers on tasks involving Convex backend development, real-time data, or database operations.
Explains the padz hybrid store architecture—files are truth, JSON metadata is a rebuildable cache. Covers self-healing reconciliation (orphans, zombies, staleness), the Backend+Store split for testability, and how to use MemBackend for unit tests. Use when working on storage, persistence, sync, doctor, or writing tests that need store simulation.
