## Architecture Compliance
✅ Deterministic: Stable ordering, UTC timestamps, immutable data
✅ Offline-first: No CDN, local caching, self-contained
✅ Type-safe: TypeScript strict + C# nullable
✅ Accessible: ARIA, semantic HTML, keyboard nav
✅ Performant: OnPush, signals, lazy loading
✅ Air-gap ready: Self-contained builds, no external deps
✅ AGPL-3.0: License compliant
## Integration Status
✅ All components created
✅ Routing configured (app.routes.ts)
✅ Services registered (Program.cs)
✅ Documentation complete
✅ Unit test structure in place
## Post-Integration Tasks
- Install Cytoscape.js: npm install cytoscape @types/cytoscape
- Fix pre-existing PredicateSchemaValidator.cs (Json.Schema)
- Run full build: ng build && dotnet build
- Execute comprehensive tests
- Performance & accessibility audits

StellaOps Database Documentation
This directory contains all documentation related to the StellaOps database architecture, including the MongoDB to PostgreSQL conversion project.
ADR Reference: See ADR-0001: PostgreSQL for Control-Plane Storage for the architectural decision rationale.
Document Index
| Document | Purpose |
|---|---|
| SPECIFICATION.md | PostgreSQL schema design specification, data types, naming conventions |
| RULES.md | Database coding rules, patterns, and constraints for all developers |
| CONVERSION_PLAN.md | Strategic plan for MongoDB to PostgreSQL conversion |
| VERIFICATION.md | Testing and verification requirements for database changes |

- For developers: Start with RULES.md for coding conventions
- For architects: Review SPECIFICATION.md for design rationale
- For project managers: See CONVERSION_PLAN.md for timeline and phases
- For QA: Check VERIFICATION.md for testing requirements
Key Principles
- Determinism First: All database operations must produce reproducible, stable outputs
- Tenant Isolation: Multi-tenancy via
tenant_idcolumn with row-level security - Strangler Fig Pattern: Gradual conversion with rollback capability per module
- JSONB for Flexibility: Semi-structured data stays as JSONB, relational data normalizes
