Kukulkan UI, LiveView, And Browser Runtime Replacement

Milestone 13 adds the 0x0-owned Kukulkan web UI runtime package. The package

defines static template surfaces, LiveView-compatible message surfaces, browser

runtime bridge data, and lightweight browser quality gates.

Runtime Contract

The UI runtime covers:

• HTML shell templates, lane cards, onboarding rows, operations rows, dashboard

fragments, asset manifest output, and route continuity with API contracts;

• /live/readiness.json, /live, /live/websocket, mount/join, event

dispatch, diff response, heartbeat, reconnect hints, and malformed WebSocket

rejection;

• browser client profile, API URL binding, OIDC callback path, event stream

path, polling fallback, and browser-visible auth/session state;

• opt-in Playwright status, Axe/WCAG report output, load/perf probe output, and

security review output under .runtime/reports/.

Gates

make kukulkan-ui-template-check
make kukulkan-live-check
make kukulkan-browser-runtime-bridge-check
make kukulkan-browser-quality-check

The parent gate is:

make kukulkan-ui-full-check

The browser quality gate does not run Playwright by default. It writes local

fixture reports under .runtime/reports/; publishing those reports to docs is a

separate explicit operation.
