Domain Schema & Architectural References

This document records the architectural constraints, entity models, and domain rules derived from the project's specifications (product-spec.md) and API contracts (openapi.yaml).

1. Domain Entities

• Refer to product-spec.md for primary entity definitions, field validations, and entity life-cycles.
• Ensure all automated actions respect business validation invariants (e.g. status transition guards, tenant isolation).

2. API Contract Alignments

• Frozen OpenAPI specification: openapi.yaml (or contracts/openapi.yaml).
• All tool calls and automation scripts must target documented endpoints and respect parameter types.

3. Database & Storage Rules

• All mutations must be executed through application endpoints or versioned migration scripts.
• Direct ad-hoc SQL table alterations or deletions without migrations are strictly forbidden by constitution.md.
