The accessibility tree is the primary browser-agent operational map. Core pages use semantic landmarks, one principal H1, native links/buttons/form controls, explicit labels, keyboard paths, visible focus, dialog focus management, status regions, and server-rendered public content.

Stable `data-agent-action` values map important creator controls to structured API alternatives in `/agent-actions.json`. Major routes provide Markdown and JSON twins. The rich local creator requires JavaScript for local ZIP/`.uaix` downloads, while equivalent public generation and compilation are available through the stateless API.

This is a project conformance statement, not third-party WCAG certification. Evidence: `https://spiralistai.com/docs/agent-readiness/accessibility-conformance-v18.md`.
