   - When a document opens with notes and with linked files that changed on disk (Update Links: Manually) or, on the web, can't be read, the status bar shows the line about the linked files, then counts the notes and names the first, and hovering it lists the notes. The same holds when the line about modified files follows the Linked File Not Found dialog, and File › New from Template… shows the notes of the file it opens as File › Open does (`an_open_with_modified_links_keeps_link_notice_and_import_notes_reachable`, `new_from_template_preserves_open_warnings`, `an_open_with_unreadable_links_keeps_import_notes_reachable`, `modified_links_after_the_missing_ones_keep_the_open_notes`, `combined_open_and_link_status_lists_notes_on_hover_and_for_accessibility`).
   - On the web, when a document opens with linked files that can't be read and linked files that changed on disk (Update Links: Manually), the status bar shows the line about the unreadable files, and the line about the changed files is the first of the notes its hover lists, ahead of the open's notes. With Ask When Modified the update question opens and the line about the unreadable files stays (`a_web_open_with_unreadable_and_modified_links_keeps_both_lines`).
   - Linked images and placed documents kept only in symbols, graph designs, patterns or opacity masks are listed in the Links panel after the layers' own, one row per stored object, with their status in its Missing and Modified filters, in Check Links, in the missing and modified files reported when a document opens, in the link watch and in Find in Folder; Relink, Update, Embed, Placement Options and Link Info act on them, and Go To says they have no place on the canvas. Opening a document gives such an object whose id is 0 or repeats another object's a new id.
+  - Linked images and placed documents in the art of the stored brushes (a scatter or art brush's art, a pattern brush's tiles) get Links panel rows of their own the same way, one per linked or placed object in each brush tile, naming the brush; Relink, Update, Embed, Placement Options, Link Info and Go To act on that art and write it back into the brush library, and the ids they are listed by are kept there. Evidence: `links_in_stored_brush_art_are_listed_and_checked_with_ids`, `links_commands_act_on_images_in_stored_brush_art_by_id`, `links_in_stored_brush_art_open_by_id_and_unreadable_entries_stay`.
   - Linked files another app changes while their document is open follow Preferences › File Handling › Update Links, as they do when it opens: Automatically reads them again (an Update Links undo step), Ask When Modified offers to, Manually leaves them modified in the Links panel. The desktop app compares the active document’s linked files by size and modification time every two seconds and when its window comes back to the front, on a worker thread; a file still being written is tried again (`links.updateChanged`).
   - A look at the linked files whose worker thread ends without a result, such as after a panic, no longer stops later looks: the app clears it, stops asking for a frame every 100 ms, and the next look starts on schedule (`crates/engine/src/tests/linkwatch.rs`, `crates/ui-egui/src/tests/place.rs`).
   - Import and paste, 2026-10-13: a multi-artboard `.ai` with notes beside its artboards opens from its editing data, a page's art past its artboard no longer lying over the page before it (#1528); a `.ai` gradient whose stops are listed upwards keeps each midpoint on the stop that starts its part of the ramp (#1530); SVG text on a path follows basic shapes (circle, ellipse, rect, line, polyline, polygon) as their SVG 2 equivalent paths (#1531, fixes #1527); PDFs whose alpha soft masks are drawn as images import with the mask instead of empty art (#1551); EPS and PostScript type set in Type 42 (TrueType) fonts imports at its size instead of 1000 times too large (#1553); PDF and EPS import keep a clipping path whose bounding box covers the page but whose shape doesn't (#1544, fixes #1542). Opening or placing a file with an image too large to decode says so, and the Links panel shows it on the row (#1540, part of #1479). Paste takes a PDF or EPS another app copied as editable vector art: from the macOS pasteboard (with SVG), EPS on Windows beside PDF, and `.eps` files copied in a file manager, with the new command `clipboard.importEps` (#1538, fixes #1499).
