Canvascope can now surface a Select from Lectra picker inside supported browser upload flows. The picker loads a student's Lectra library through the extension background worker, shows searchable document rows, renders PDF thumbnails without breaking strict page security rules, and fills the page's file input with the finished PDF.
The first consumer is Gradescope's upload modal, but the important part is the generic layer underneath it. Attach from Lectra is page-agnostic, so future assignment upload flows can use the same document picker instead of rebuilding the bridge one page at a time.
Lectra also got release-build polish on the same day: cleaner export names, editor and library fixes, Xcode Cloud setup, shared scheme work, and cleanup around accidental dependency tracking. The goal is simple: annotate on iPad, then bring the finished file back to the browser without hunting through downloads.
