Merges two complementary architectural patterns: 1. Quality Enforcement Layer - Prevents premature agent completion 2. Orchestration Layer - Manages multi-agent context and assignment Key features: - 50% rule for issue sizing - Agent profiles and cost optimization - Context monitoring (compact at 80%, rotate at 95%) - Mechanical quality gates (build, lint, test, coverage) - Forced continuation when gates fail - 4-week PoC plan Addresses issue #140 and L-015 (Agent Premature Completion) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Architecture
Technical architecture and design principles for Mosaic Stack.
Chapters
- Overview — System design and component architecture
- Authentication — BetterAuth integration and OIDC flow
- Design Principles — PDA-friendly patterns and UX guidelines
Architecture Principles
- Type Safety First: Shared types prevent frontend/backend drift
- Multi-Tenant Ready: Row-level security with workspace isolation
- PDA-Friendly: Calm, stress-free language and visual design
- Modular: Plugin architecture for extensibility
Technology Decisions
Key architectural choices and their rationale:
- BetterAuth over Passport.js for modern authentication
- Prisma ORM for type-safe database access
- Monorepo with pnpm workspaces for code sharing
- PostgreSQL + pgvector for AI-ready data storage
Next Steps
- Review API for implementation details
- Check Development for workflow standards
