 Hermes owns the harness. Training should flow from Timmy's lived work and DPO
 artifacts, not from re-growing a bespoke training pipeline inside every repo.

+## 2026-03-29 — Canonical separation defined: Timmy, Ezra, Bezalel
+
+Spec: `specs/timmy-ezra-bezalel-canon-sheet.md`
+
+Local Timmy remains the sovereign local house and control plane.
+Claude-Hermes and Codex-Hermes are not blended into Timmy; they become named
+wizard houses with explicit roles:
+- Ezra = archivist / scribe / repo-and-architecture wizard
+- Bezalel = artificer / builder / forge-and-testbed wizard
+
+This boundary is now both canon and system architecture.
+All future research, backlog, and implementation flows should preserve explicit
+producer identity, local review, and non-blended authority.
