What this changes

Three things a reviewer working with comments across documents needs (parity comment.copy-paste and comment.multi-select, both new and shipped; comment.export-selected to partial; comment.polyline notes):

• Copy and paste comments, within and between documents. ⌘C with comments selected (and no text selected) copies them, each with its replies, as XFDF: into the app's clipboard (every tab and window) and as text onto the system clipboard. ⌘V or Edit ▸ Paste comments hangs the copies on the pointer as one bundle: their box with a count, and each comment's outline in its own colour (boxes, lines, polygon and polyline vertices, ink strokes, text-markup quads, callout leaders) so the drop can be aimed to the line; a left click places them, centred there, on the page clicked, so a copy never lands on its original and a bundle copied from an A0 page goes where it fits on an A4 one (placed as it is when larger than the page, with a notice). Escape or a right-click lets the bundle go. The page's context menu places the bundle at the point the menu was opened at. The copies are new comments under names of their own, so nothing is replaced and pasting twice gives two sets; they are selected afterwards. XFDF with comments arriving from the system clipboard pastes too, so comments travel between PdfCraft processes (and from any XFDF text). The Comments panel's card menu copies that card's comment.
• Several comments at once. ⌘-click (Ctrl on Windows and Linux) or ⇧-click adds a comment to the selection or takes it out again, on the page and in the Comments panel; the one clicked last has the handles and is what Properties, Reply and the quick bar act on. Delete (key or menu) removes every selected comment as one undo step ("Delete comments"), dragging one of them moves them all (text markup stays with its text; one undo step "Move comments"), the context menu copies them all. A plain click or Escape selects one alone again.
• Connected lines, polygons and clouds finish from the right-click menu (Complete; Undo last point and Cancel drawing beside it), as other editors do, besides Enter and a double-click.

How it works

• pdfcraft_xfdf::export_xfdf_comments(doc, &[(page, index)], file) writes the selected annotations and, transitively, their replies (/IRT). pdfcraft_xfdf::import_comments(doc, text, page, fresh_prefix) imports XFDF comments as copies: every comment lands on page (or its own), under <prefix>-<n> names when a prefix is given, with inreplyto remapped within the batch (a reply whose parent was not copied stands alone instead of attaching to a same-named comment the document happens to have). Field values in the text are ignored for a paste. The usual import is unchanged (same names replace, as documented).
• Engine: Edit::PasteComments { xfdf, page, offset } (the copies moved by an offset in user space; pdfcraft_xfdf::comments_bounds / comment_count / comment_outlines tell what hangs on the pointer) (label "Paste comments", Scope::Comments, needs the comment permission like AddAnnotation; the names come from the edit context's id generator, so they are unique within the document) and Session::export_comments(id, which). A paste that adds no comment is refused as an error, so a stray text never produces an empty undo step.
• Tools: comments_copy {doc, comments: [[page, index], …]} → {xfdf, comments} (read-only) and comments_paste {doc, page, xfdf, at?} (undoable; at centres the bundle there, in comment_add's page coordinates).
• UI: CommentView keeps selected (the one with the handles) and also (the others) with selection(), is_selected, select_only, toggle, clear_selection; the clipboard is PdfCraftApp::comment_clipboard (CommentClip { xfdf, count }); registry commands comment.copy / comment.paste (Edit menu). ⌘C/⌘V arrive as egui's Copy/Paste events and are left to a focused text field; the Organize grid keeps ⌘V for pages.

Not yet

Appearance streams and file attachments' data are not carried (the copies are drawn again; an attachment comment is copied without its file); a rubber-band selection; ⇧-click as a range in the panel; Export selected comments to a file from the interface (the tool and the clipboard have it).

Tests. crates/xfdf/src/tests.rs: selected export takes the comments and their replies and nothing else; copy-import lands on the asked-for page with fresh names, a second import gives a second set, an unknown page is refused unchanged, the usual named import still replaces. crates/engine/src/tests.rs::pasting_copied_comments_adds_copies_that_undo_as_one_step. crates/automation/tests/automation.rs::comments_copy_and_paste_between_documents_through_tools. crates/ui-egui/tests/comments.rs: ⌘-click selection and Delete as one step (with undo), copy and paste into another document (Edit menu with placement by click, page menu at its point, ⌘V with Escape letting go, XFDF from the system clipboard, plain text refused), connected lines completed from the context menu (Complete disabled with too few points, Undo last point, Cancel drawing). tests/commands.rs::every_registered_command_is_implemented covers the new commands.

Never-crash

No new unwrap/expect/panic! outside tests; positions go through get(); the import bounds its pages (pages.get), refuses a page the document lacks, and goes through the existing XML depth/node limits; indices in a batch delete are deleted later-first so earlier positions stay valid. No unsafe.

Provenance

No new assets (Lucide clipboard-paste and copy are already in assets/icons/), no fonts, no copied code. Behaviour from Acrobat's documented comment copy/paste and selection behaviour and the XFDF specification.

Security

--root confinement untouched (the tools take text, not paths). The import keeps its limits on XML depth and node count; a pasted redaction mark is made visible as before.

Merge Risk: Low · previous review 0ed6f

Copy, paste and multi-selection work overall, but a few edge cases misbehave:

• Right-clicking with several comments selected can make Delete, Colour or Copy act on the wrong set.
• A locked comment in the selection stops a group drag from moving anything.
• The menu's Complete can do nothing for a drawing on a later page.
• A paste centred on a point can land off-centre when the copy includes replies.

None of these loses data permanently, and undo or a retry recovers from each. They are worth fixing soon.

Security architecture risk: Low · up to 0ed6f

Permission checks and undo isolation contain the new comment-transfer behavior. Direct placement can nevertheless target the active document rather than a requested non-active tab, although current UI callers use matching tabs. Large-input handling and the policy for copying restricted comments remain incompletely established.

Retained concerns

• Low · architecture · observed: Direct-placement paste validates the supplied tab index but delegates mutation to an active-document operation. A non-active public caller therefore checks one document and changes another. Current UI callers use the active tab, and the engine checks the actual destination's permissions, limiting this to a destination-ownership contract defect rather than a demonstrated permission bypass.

Security review details

Security Blast Radius

• inferred — The established exposure is caller-supplied clipboard or automation XFDF entering an open document's annotations, and selected comments plus replies leaving through the system clipboard. Mutation remains subject to the actual document's annotation permission; no broader service, credential, or infrastructure authority was established.

Trust Boundaries and Controls

• observed — Untrusted XFDF crosses a restricted annotation mapping rather than importing arbitrary PDF dictionaries. The inspected mapping does not import action or external-resource payloads. XML DTDs are disabled, depth and node-count limits are retained from the base, target pages are validated, and copy-paste callers bypass form-field processing.

Resilience and Maintainability Implications

• observed — Clipboard placement parses input for counting, bounds, and outlines before mutation. Geometry parsing collects coordinate vectors. XML structural limits therefore do not alone establish a byte or geometry-work budget; application-wide limits and practical exhaustion thresholds remain unverified.

Hardening Proposals

• proposed — Define shared byte, annotation-count, and geometry budgets before preview or import allocation. This would strengthen containment for hostile clipboard and automation inputs; it is not a demonstrated denial-of-service finding.
• proposed — Make the policy for exporting comments from copy-restricted documents explicit and apply it consistently across clipboard and file export, without treating the existing policy ambiguity as a newly verified bypass.

Clear older selections when adding a comment.

If the user has selected several comments and then draws a new one, the drawing path clears selected but leaves also intact. This branch selects the new comment without clearing also. A subsequent Delete can therefore remove older comments along with the new one. Use select_only when selecting a new annotation, and clear the full selection for the ink branch.

Thanks for the review. Addressed in 5f0e00e:

• Clear older selections when adding a comment (editing.rs): adding a comment now selects it alone (clear_selection before selected = newest), and the ink branch clears the whole selection.
• Dispatch context-menu Copy through comment.copy (canvas.rs): the page menu's Copy runs app.execute("comment.copy"); the point-targeted paste keeps its parameterized path.
• Keep the reply draft on one comment (comments_panel.rs): the reply field shows on the comment with the handles only (selected == Some(key)); the other selected cards are highlighted without it.
• Keep the selection after a group move (editing.rs): a batch that only moves comments keeps the selection; a delete batch clears it.
• Select annotations that the paste actually added (editing.rs): apply_edit records the page's annotation names before a PasteComments and selects exactly the new ones afterwards, instead of the last comment_count.
• Fresh name per pasted comment (xfdf): every copy is named from its own position, renamed maps a source name to its first copy (so inreplyto resolves to one), and by_name holds the name the node received; two source comments sharing a name give two copies (test comments_written_directly_into_the_page_array_copy_and_shared_names_give_two_copies).

One more fix from use, in the same commit: comments another tool wrote straight into a page's /Annots array (no object of their own) did not copy, because the selection was matched by object reference. The export now filters by position (page, index); replies still follow their parent's reference.

Second round addressed in 37a4df7:

• Preserve replies to selected parents without /NM (xfdf): a selected annotation that has no /NM now gets a name for the export, pdfcraft-<page>-<index>, kept clear of the document's existing names; it is written as the element's name and used for its replies' inreplyto, so the copy import maps it to the parent's fresh name like any other. Existing /NM values are untouched and the whole-document export is unchanged. Test replies_to_a_selected_comment_without_a_name_follow_it_into_the_copy (parent stripped of its /NM, exported with its reply, pasted: the reply follows the copied parent).

🟡 Minor · Include direct annotation names in synthetic-name allocation. · lib.rs:312-335

crates/xfdf/src/lib.rs:312-335
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Include direct annotation names in synthetic-name allocation.

When a direct page-array annotation has /NM = pdfcraft-{page}-{index}, this loop does not add that name to taken because direct annotations have no ObjRef. A selected unnamed indirect parent at that position can therefore receive the same export name.

If the direct annotation appears first, copy import maps the duplicate name to that annotation. The selected parent’s reply can then attach to the copied direct annotation instead of the copied parent.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Exclude replies from placement bounds.

When a copied comment has a reply with a distant rectangle, comments_bounds shifts the paste center toward the reply. Replies have no visible placement outline, so both pointer placement and automation at placement can place the top-level comments incorrectly.

Suggested fix

-    for (_, _, rect) in comment_nodes(text) {
+    for (_, in_reply_to, rect) in comment_nodes(text) {
+        if in_reply_to.is_some() {
+            continue;
+        }

[ohagmann]

Third round addressed in e250daf: every /NM in use is reserved before an export name is given, including those of annotations written straight into the page's array (no ObjRef), so a selected unnamed parent can't be given a name such an annotation already carries. The test replies_to_a_selected_comment_without_a_name_follow_it_into_the_copy now adds a direct annotation under the name the parent would get and checks the parent's export name steers clear of it while its reply still follows it.

[FredApps]

Code-only review at e250daf; no CI has run on this head yet. I read the whole source diff (the i18n catalogue lines aside).

Two defects to fix:

1. Dragging a selected comment that is not the primary one drops the primary from the selection. In select_input (crates/ui-egui/src/comments.rs, the Gesture::Move start), when the grabbed comment is already selected the code does cv.selected = Some(grabbed); cv.also.retain(|k| *k != grabbed). The previous selected is never pushed into also. With A, B and C selected (C primary, as after two Ctrl-clicks), dragging A leaves selected = A, also = [B], so C stays behind and the Batch moves two comments instead of three. It also contradicts the comment above it ("Dragging one of several selected comments moves them all"). Keep the old primary: if let Some(prev) = cv.selected.replace(grabbed) { cv.also.push(prev) }, then remove grabbed from also. No test drags a non-primary member of a multi-selection; please add one.

2. ⌘V with unrelated text on the system clipboard starts a comment paste. In copy_key (crates/ui-egui/src/lib.rs), from_system is Some only for XFDF, but the next line pastes whenever from_system.is_some() || self.comment_clipboard.is_some(). If someone copies comments, then copies a word in another app and presses ⌘V in the viewer, the old comments hang on the pointer. The comment above says a non-XFDF text should not trigger it; the code lets any text through. Only fall back to comment_clipboard when the pasted text is empty. The test covers the empty-string paste and "just text" with no in-app clipboard, but not "just text" with one.

Smaller points, no change required to merge:

• annots_with_replies now carries the old /// Every comment as an XFDF element… doc line plus two near-identical paragraphs, and xfdf_annots has no doc comment.
• This bundles three features: comment copy/paste through XFDF, multi-select with group move and delete, and Complete/Undo last point/Cancel in the context menu. Splitting them would make each easier to review.

[anssariworks]

This PR covers the Ctrl+click selection and bulk-delete parts of a review workflow I need. The remaining request is to apply colour changes to every selected annotation, rather than only the last-selected annotation.

Shift+click range selection in the Comments panel would also help select consecutive comments. The PR already lists this as a remaining limitation. If these additions are outside this PR's scope, could they be tracked as follow-ups?

[ohagmann]

@FredApps Thanks for the careful read — both were real. Addressed in 0ed6f7a (the branch is also rebased onto current main, which it had fallen into conflict with):

1. Dragging a non-primary member of a multi-selection. The grabbed comment now takes the handles and the previous primary is pushed into also (then the grabbed one is removed from it), so A, B and C all move when A is dragged. New test dragging_any_selected_comment_moves_the_whole_selection: three rectangles, the first and last selected by ⌘-click order, the first one dragged; all three move by the same offset, all three stay selected with the grabbed one as primary, one "Move comments" step.
2. ⌘V with unrelated text. copy_key now pastes from the system clipboard only when it holds XFDF with comments, and falls back to the in-app clipboard only when the pasted text is empty (nothing legible); any other text is left alone. copied_comments_paste_into_another_document now also covers a word pasted while comments are in the in-app clipboard (nothing hangs on the pointer), then an empty paste (the copied comments do).

Smaller points: the stale doc paragraphs on annots_with_replies are gone and xfdf_annots has its doc comment.

On splitting: the three parts share the selection model (selected + also), which copy/paste and the group move are built on, and the context-menu Complete/Undo/Cancel is a few lines in the same menu function. I'd keep them together unless you'd rather review them separately — then I'm happy to split the context-menu part into its own PR.

Also new since your review, each in its own commit, from using the branch on real protocols and plans:

• Copied Fill & Sign marks and text boxes hang on the pointer as themselves (a4e3354). A copied tick, cross, dot or line showed as an empty box while the bundle was placed, which read as if the mark had been lost. The outlines now draw a mark's own strokes (and the dot as its circle) and a text box's text in its box, size and colour (Outline::Text). FillMark::strokes is the one definition of a mark's strokes: the appearance strokes it and the outline draws it. Test: crates/xfdf/src/tests.rs::copied_marks_and_text_boxes_show_what_they_are_while_placed_and_once_pasted.
• Properties and Colour change every selected comment (78dc796), as @anssariworks asked below. With several selected, Comment Properties (opened on one of them), the context menu's Colour and the quick bar's colour changed only the one with the handles. They now change all of them as one undo step, each where the property applies (a font size to text, a fill to shapes, a width to lines and shapes); unticking Locked unlocks them all, and one that stays locked keeps its look. The dialog says how many it changes (new string in all 22 catalogs). Test: crates/ui-egui/tests/comments.rs::properties_change_every_selected_comment_where_it_applies.
• ⇧-click in the Comments panel selects a range (in 0ed6f7a, CommentView::select_range), also from @anssariworks.

Gates on this head: fmt, clippy -D warnings (annot, xfdf, engine, automation, ui-egui), tests annot 45, xfdf 57, engine 284, automation comment* 7, ui-egui lib 473 / comments 56 / commands 24, xtask parity.

[ohagmann]

@anssariworks Both are in now:

• Colour for every selected annotation: Comment Properties (opened on one of several selected), the context menu's Colour and the quick bar's colour change all selected comments as one undo step, each where the property applies; a locked one keeps its look (78dc796).
• ⇧-click range in the Comments panel: selects the cards from the one with the handles to the one clicked, in the panel's order; another ⇧-click from the same card changes the range; ⌘/Ctrl-click still adds or removes one (0ed6f7a).

🟡 Minor · Right-clicking a comment does not update the multi-selection. · comments.rs:853

crates/ui-egui/src/comments.rs:853
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Right-clicking a comment does not update the multi-selection.

Line 853 assigns cv.selected directly and leaves cv.also unchanged. With several comments selected, this causes two failures:

• Right-click on an unselected comment: that comment becomes primary, and the earlier selection stays in also. "Delete comments", Colour and Copy then act on the earlier comments as well.
• Right-click on a secondary comment: the old primary is replaced but not pushed into also, so it drops out of the selection. selection() filters the duplicate key. "Delete comments" then skips the comment that had the handles.

In both cases the menu acts on a different set of comments than the user expects. Undo can reverse it. Use the same rule as the drag path at lines 1188-1201:

• If the right-clicked comment is not selected, select it alone.
• If it is already selected, make it primary and keep the rest of the selection.
• If nothing is under the pointer, clear the selection.

🐛 Proposed fix

         cv.context_at = Some((cx.page, cx.to_user(p)));
-        cv.selected = cx.hit(p).map(|a| (cx.page, a.index));
+        match cx.hit(p).map(|a| (cx.page, a.index)) {
+            Some(key) if cv.is_selected(key) => {
+                if let Some(previous) = cv.selected.replace(key)
+                    && previous != key
+                {
+                    cv.also.push(previous);
+                }
+                cv.also.retain(|k| *k != key);
+            }
+            Some(key) => cv.select_only(key),
+            None => cv.clear_selection(),
+        }

The promote-to-primary logic now appears twice: here and at lines 1195-1200. You could move it into a CommentView::make_primary(key) helper.

[FredApps]

Re-review at SHA cb43fad (my last APPROVE was at 5489da4). The hosted run tested a different base, so the gate is the fork CI of the same head and target (FredApps#15). Gate is green.

What changed: the author rebased onto main's module split, so about 750 diff lines differ from my baseline. I compared them at content level: the XFDF code (crates/xfdf/src/xfdf.rs, lib.rs) and the ui-egui file moves (comment_props, comments_panel, tools/comments/*) are moves of code that is already in main, not new behaviour. The behaviour that belongs to this PR, which I read in full:

• Edit::PasteComments (engine): runs pdfcraft_xfdf::import_comments with a prefix from the edit's own id, so copies get new names and pasting twice gives two sets; an empty import is an Invalid error. It is listed with the other annotation edits in check_permission and in scope_of, and has an edit label.
• Session::export_comments: exports the chosen (page, index) comments with their replies as XFDF.
• copy_key, copy_selected_comments, paste_comments (app/clipboard.rs): text selection wins over comment copy; paste only reads the system clipboard when it is XFDF with comments (so a word copied elsewhere is not replaced by stale comments), and checks allows_annotation first. With no target the bundle hangs on the pointer (Gesture::Place) and a click places it; Escape or right-click cancels.
• Multi-select (CommentView::selection, toggle, select_range, select_only, clear_selection): ⌘/⇧-click, grab-and-drag keeps the group, and Move and Delete become one Edit::Batch, deletions in descending order so indexes stay valid. quick_bar colour now applies to the whole selection.

Checked: the permission and scope wiring, the index ordering in the batched delete, the Place gesture bounds notice, and that the tests cover the multi-select delete and the copy/paste round trip by name.

Not verified: I did not run anything locally; the tests were read, not executed. A small nit, not blocking: in state.rs the doc line "Copied pages: …" now sits above CommentClip and PageClip has lost its doc comment.

Hosted fork CI validated upstream head cb43fad merged with target 7555be3. Test candidate 2b240c8 differs only in fork workflow configuration. SonarCloud excluded.

[ohagmann]

Rebased onto main (3109bb23, which has #5236's integration of 13 fixes). main dropped FieldPointer from the form-field check, so the pointer bundle's !placing sits in main's simpler check. bf1be0f is FredApps' nit: PageClip has its doc comment back and CommentClip its own. ce1ba2f: the bundle on the pointer claims its cursor through view.cursor.claim, as main's new guard test asks of page modules. Gates on this head: cargo fmt --check, clippy -D warnings and the tests of annot, automation, engine, ui-egui, xfdf (2678 passed), xtask layers, assets, parity.

[ohagmann]

Rebased onto main (f137a289, after 0.16.1). What met main:

• Page router: the multiple selection now happens in the Select tool's owner match (a drag of one selected comment moves them all, ⌘/Ctrl- or ⇧-click toggles one, a double-click selects that one alone).
• Delete: main checks each comment with the engine (annotation_deletable: a locked comment, or one with a locked reply, stays). The page menu's Delete now asks that for every selected comment, instead of the branch's own lock test.
• Selection after edits: main's annotation_deleted keeps the selected comment where it moved after a delete; it now does the same for the other selected comments. history_stepped (undo, redo) clears the whole selection. A paste selects what it added by comparing with the page's comments before it, which main already collects for deletes (annots_before), instead of a list of its own.
• Copied comments on the pointer: main's simplified form-field branch also leaves the click to the bundle.

[ohagmann]

Rebased onto main (47f42ba0). The catalogs (main's new page-edge-shadow label) and ATTRIBUTION met; the change applied as it was. With main's shadow switch document_area came to a cognitive complexity of 31 (limit 30), so one commit on top moves this PR's choice of the page's tool (Select while copied comments hang on the pointer) into page_tool(); no change in behaviour.

[ohagmann]

Rebased onto main (41652972, 0.17.0). Main reworked two places this PR builds on, so the PR is now one commit with the conflicts resolved once (its history was 24 commits of rebases and review fixes):

• Keys. Main's clipboard_keys (copy, cut and paste of images, pastes delivered as events) replaces copy_key. In it, ⌘C with no text selected copies the selected comments first, as before; a pasted text reaches the canvas as ClipboardPaste::Text(text) (main kept no text), and paste_comment_text pastes it as comments when it is XFDF with comments, or the app's own copied comments when the system clipboard holds nothing legible. Text fields, dialogs and the page grid keep their pastes, as main has it.
• Menus. Main's page menu (default_page_context_menu) is shown when no comment is selected, the comment menu only for a selected comment. Paste comments is now in the page menu (PageMenuAction::PasteComments, shown while comments are copied), and the comment menu also opens while connected lines are being drawn, so Complete, Undo last point and Cancel drawing stay there.

Also: lib.rs's exports met main's recent-files constants (both kept), and the ATTRIBUTION changes are out (catalog history is the record since #4284).
