01 / SELECT
You choose the text
Use the context menu or side panel on the active tab. No background page scraping.
Browser extension
Verify selected text without surrendering the page.
A Manifest V3 side panel sends only text you explicitly select. The extension does not inject a content script into every page and does not persist API keys in local storage.
02 / VERIFY
Session-scoped state
Selected content and any temporary credential are held only in extension session storage.
03 / INSPECT
Same result contract
Coverage, abstention, evidence destinations and limitations remain visible in the panel.
Installation
The rebuilt extension is packaged from the canonical private repository. Store publication is a separate review and release step; until that package is reviewed and signed, load the release folder through Chrome’s extension developer mode only on a trusted machine.
Permissions
contextMenus: creates the explicit “Verify with Mephistopheles” selection action.sidePanel: displays the workbench without modifying the page.activeTab: permits a one-time, user-triggered read of the selected text.storage: holds short-lived state inchrome.storage.session.
No invisible whole-page verification.
Chrome permissions and page restrictions can prevent selection access. The extension reports that boundary instead of broadening host permissions silently.
