City Interface Layer — Notion ↔ GitHub Pages

<aside> ↔️

PUBLIC LAYERING CONSTRUCT

Notion carries explanation, research context, provenance and editorial navigation. GitHub Pages carries executable interfaces. AETHERIS carries operation → receipt → state. E47 / Kartekeya carries the invariant mathematical substrate.

All external interface, source and evidence destinations remain intentionally OPEN.

Public interaction grammar

Every district exposes the same four doors without forcing a single hosting choice.

Door	Role	Binding
LEARN	Explanation, paper, figures, context, history	OPEN
OPEN LIVE	Executable simulator, visualizer, game, instrument	OPEN
SOURCE	Inspectable repository, package or implementation record	OPEN
EVIDENCE	Certificate, receipt, validation, provenance record	OPEN

Navigation contract

READ → RUN → INSPECT → RETURN

Notion explains the object without duplicating the runtime.
GitHub Pages executes the object without becoming the research archive.
Live interfaces may move between hosts without changing the Notion information architecture.
Source and evidence references may point to GitHub, Drive, Supabase, Notion, certificates or future systems.
No district is required to adopt a single canonical external host.
Existing live interfaces remain untouched until explicitly bound.

District topology

The public City remains one entry system with multiple independently addressable instruments.

Binding rule

A destination becomes bound only when an actual public endpoint is deliberately selected. Until then, the slot remains OPEN rather than inheriting a stale URL from an older app.

This layer is additive. It does not replace, move, disable, redirect, or adjudicate any existing interface.
