web: open the Windows app from /auth (cascade:// handoff)#15
Merged
Conversation
PR #13's static /auth page shows the magic-link token with a Copy button and relies on Apple Universal Links to open the native app automatically. Windows has no Universal Link for an unpackaged app, so the link minted with &app=windows (server, #14) only ever showed the copy-the-code fallback. When app=windows is present, redirect to cascade://auth?token=... so the desktop app launches and signs in, with an "Open Cascade" button as the fallback if the browser blocks the programmatic protocol navigation. The copy-the-code path remains for when the app isn't installed. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

What
Completes the Windows deep-link sign-in. PR #14 made the server append
&app=windowsto the emailed link, and the Windows app registerscascade://. But PR #13's static/authpage (which now owns/auth) only shows the token + Copy button and relies on Apple Universal Links to auto-open the native app. Windows has no Universal Link for an unpackaged app, so the link did nothing automatic there.This makes
/auth/index.htmlredirect tocascade://auth?token=…whenapp=windowsis present:location.href),Why this and not the SPA
useSync.tschange from #14#14 put the handoff in the SPA, but
/auth/index.htmlis a real static file, so Apache serves it directly and the SPA never runs for/auth. The handoff has to live in the static page. (The SPA branch is now dead for the email flow but harmless.)Verify after deploy
