The curated docs surface may publish selected decisions and closure records, but it should not flatten the whole notes graph.

v0.4 release closure

The native proof path is the shipped runtime; follow-up work tightens contracts instead of reopening the architecture transition.

v0.4 Release Closure

Repomix decommission and oracle boundary cleanup

The adapter/oracle seam is parity and diagnostics only, not an ordinary runtime dependency.

Render Kernel Contract

Shared handover naming

The handoff artifact is shared handover, not bundle-index language, because it carries cross-section context and trust metadata.

System Contracts

Latest-only schema publishing

Pages and the npm package publish only the latest schema for each family; retired schema endpoints are intentionally removed.

If you consume schemas

Notes remain separate from canonical docs

The note graph preserves durable cognition and historical pressure, while promoted docs carry stable architecture claims.

Architecture Overview

Source of historical pressure

Use promoted notes and release docs for durable decision history. Keep exploratory or transitional reasoning in notes/.

Promotion Rule

A note becomes architecture documentation only when it states a durable decision, invariant, mechanism, or failure mode that operators should depend on. Exploratory reasoning can remain valuable without being promoted into the curated docs surface.
