Why

Run currently always calls window.turnstile.execute() and only settles on callback / error-callback. In CI (Playwright against 127.0.0.1, production sitekey) that can throw or never callback, so /run waits 120s.

The server already skips siteverify when TURNSTILE_SECRET_KEY is empty. The client should skip the widget the same way on loopback.

What

TurnstileGate with two implementations:

  • NoopTurnstileGate — returns '' immediately. Used on localhost / 127.0.0.1. The Turnstile api.js script is not loaded there either.
  • CloudflareTurnstileGate — documented execute-on-Run: render(..., { execution: "execute", appearance: "interaction-only" }), then reset(widgetId) + execute(widgetId) on each Run. No 8s client deadline. Overlapping getToken shares one in-flight promise.

Override with window.__TRY_PLAYWRIGHT_TURNSTILE__ = 'noop' | 'cloudflare'.

Also: getCode() after await, loader only after the token, Run disabled while in flight.

Test plan

  • cd frontend && npx playwright test src/turnstile.spec.ts
  • CI e2e

Keep execute-on-Run. CloudflareTurnstileGate now follows the
documented explicit lifecycle (render with execution=execute, then
execute(widgetId)). Interactive challenges stay visible, have no
8s client deadline, and overlapping Run clicks share one in-flight
token request.

Automated browsers (navigator.webdriver) default to the noop gate so
CI on 127.0.0.1 does not hang. Humans on localhost, including Vite
proxying to production, still use Cloudflare. Override with
window.__TRY_PLAYWRIGHT_TURNSTILE__.

Use the noop gate (and do not fetch api.js) only on localhost /
127.0.0.1, or when window.__TRY_PLAYWRIGHT_TURNSTILE__ is set.
Production still follows render-then-execute on Run.
