 - **2026-10-09 (M14, #577):** The desktop GPU setup enables the selected adapter's supported 2D texture extent instead of egui-wgpu's fixed 8192-pixel extent. This removes the artificial surface ceiling behind a mixed-DPI Windows startup crash when opening Outlook PDF attachments. Synthetic regressions cover the observed 8600 × 3423 surface, downlevel adapters and preservation of other device limits. Hardware resolution limits still apply; milestone and overall effort estimates are unchanged.

Move, resize, restyle and undo/redo preserve that orientation. Native and external Poppler save/reopen rendering cover all four quarter-turns; UI tests verify the displayed bounds.

 - **2026-10-08 (M5.7, signature resize proportions):** Image signature corner handles preserve the embedded image's original aspect ratio and anchor the opposite corner; edge midpoint handles stretch width or height independently. The live preview and committed edit share the constrained geometry, including page/view rotation and reopened PDFs whose rectangles were stretched previously. Synthetic UI tests cover all corners, edge resizing, undo and redo. Milestone and effort estimates unchanged.
 - **2026-10-08 (M5.7, live signature adjustment):** Embedded image signatures resize and move with every pointer frame. Movement hides the frame and handles, which return on release; Escape cancels without committing. A cached background preserves the page beneath the image, and only the completed gesture enters undo history. The read-only engine preview and `comment_image_preview` tool share bounded image decoding and render layers. Synthetic pixel tests cover live geometry, alpha, coloured page content, rotation, cancellation and encrypted save/reopen. Milestone and effort estimates unchanged.
 - **2026-10-08 (M10/M4, create from multiple files):** Create a PDF ▸ Multiple files is live. The picked PDFs, images and `.txt` files open as one unsaved document in the Organize page grid, where pages are removed and reordered and Save pages writes what is shown. The grid gained a "+" at every gap that inserts files right there, and on desktop files dropped on the grid go to the gap under the pointer; Insert from file now takes several files in order, converts images and text, and selects what it inserted. File-type detection moved from the shell into `pdfcraft-create` (`source_kind`), with one engine entry point (`Session::convert_to_pdf`) shared by Open, Insert, Create and the new `doc_create_multiple` tool (which can also write one PDF per file). Not yet: Office/HTML/Markdown inputs, PDF Portfolios, progress for big batches, dropping onto the grid in the web build. Overall estimate unchanged (about 30–35%).
