freeze-contracts — Boundary Partitioning & Interface Contract Locking

Domain Rubric

1. Bounded Context Isolation

Isolate domain boundaries so each context exclusively owns its datastore and internal state. Forbid direct cross-database queries or foreign entity mutations; require all cross-boundary interactions to traverse explicit Public Interfaces, Domain Events, or Anti-Corruption Layers (ACL).

2. Contract Specifications & Consumer Fixtures

Define cross-module contracts using strict typed declarations (TypeScript types, Protocol Buffers, JSONSchema, OpenAPI, or Go interfaces). Every contract must declare protocol, direction, typed command/event payloads, error models, and mock provider fixtures so downstream consumers can build independently without upstream readiness.

3. State

• STAGED: Bounded contexts mapped, public interfaces frozen, and mock fixtures reviewable.
• UNRESOLVED: Domain boundary ambiguity or conflicting data ownership prevents clean separation.
