Proposed. Decision date: 2026-07-31. Revision: 2026-07-31.

This ADR defines a target architecture. It does not claim that the target registries, schemas, commands, evidence receipts, governance rules, or metrics already exist. Each non-trivial implementation slice requires a dated spec, stable acceptance criteria, risk evidence, and the validation appropriate to the affected capability.

Acceptance requires the validation gate at the end of this ADR and an explicit maintainer decision. Accepting this ADR approves the target architecture only; it never activates a target owner. Existing canonical owners remain authoritative until an implementation spec records a per-slice cutover in the activation ledger defined below. A missing ledger entry always means "keep the existing owner."
