Application ABI

One framework-neutral lifecycle contract for vanilla, React, and Vue applications.

Governed delivery

Resolve by environment, tenant, cohort, version, or channel before loading.

Isolation choices

Use DOM, Shadow DOM, or cross-origin iframe behind one Host transaction.

Safe replacement

Stage until ready, commit atomically, and keep the current application on failure.
