What this is

The Loupely Lens Chrome extension shipped its first working build. The extension installed on any website in Chrome, the picker activated, and captures downloaded as structured files. The backend infrastructure was built from scratch: a Supabase development project with shared users, credits, and sessions tables, a deployed lens-diagnose.ts Edge Function stub, and the useloupely.com auth callback page and extension-ids.json file that the magic link authentication system depended on.

Authentication shipped end-to-end using magic links. An email field, a send-link button, a 60-second resend countdown, and a post-click idle state. No password. The session survived extension reinstalls and worked across devices. The service worker stored the access token in module scope only, following the Loupely v5.3 auth-manager security model.

Captures were written to chrome.storage.local via a relay mechanism, not via direct download from the content script. The popup read the relay on open and served the download. A diagnostics page was added for internal development use.

Why we built it

The narrowest possible working slice first. Every subsequent feature was built on top of this foundation. Nothing else could start until the picker worked, the relay wrote, and the file downloaded.
