Initialized Chrome extension project with manifest, background script, options page, and popup UI
Implemented basic file upload flow from the extension to Storacha Space
Spent the week deep diving Chrome-extension architecture, permissions, and messaging patterns

What went well
- Successfully built the first working version of the extension UI + background service worker.
- Verified that files selected in the browser can be streamed to Storacha with the existing terminal logic ported to JS.
What was difficult
- Understanding Manifest V3 restrictions and adapting the UCAN email login flow inside an extension context.
- Troubleshooting CORS issues when invoking the w3up-client from a service worker.
The current build focuses on “happy-path” uploads.

No new demo this week; recording will follow once testing passes.

End-to-end testing of the Chrome extension in Chromium and Chrome stable
Add robustness checks:
- Selective sync (file-type / size filters)
- Hidden-file exclusion
- Ensure only one Storacha Space is delegated
Record and publish demo video of extension workflow
