Engineering Standards

The current codebase follows a few consistent rules:

• prefer strict TypeScript and typed boundaries
• keep tenant context server-derived
• keep wallet and reward writes transactional
• keep append-only data append-only
• use DB constraints for deduplication and uniqueness
• keep provider integrations behind small adapter layers
• keep UI route guards as UX only, not security
• keep docs aligned to the current code rather than the original plan
