ADR-001: Multi-Repo over Monorepo

Status

Accepted

Context

Need isolation of domain evolution, independent versioning, separate CI cost control.

Decision

Adopt multi-repository per domain + shared versioned libraries (BOM, core-common, security-lib, event-core, test-core).

Consequences

• Independent release cadence
• Clear domain boundaries
• Harder cross-repo refactors (mitigate by shared libs & contract tests)
