📝 SummarySummary by CodeRabbit
WalkthroughThe PDF feature replaces one centralized state object with independent document primitives for viewer state, navigation, annotations, definitions, markup, tabs, persistence, and comments. Components and hooks now use these APIs. Definition and table-of-contents state is simplified. Annotation and comment mutations use command methods. New tests cover primitive isolation, viewer behavior, annotations, comments, tabs, search, and placeables. AI actions were removed from the PDF popup. Priority: ➖ Normal Merge Risk: 🟠 High · up to PDF edits or bookmarks can be lost, while navigation and annotation failures can disrupt normal document use. These issues should be fixed before merge. 🚥 Pre-merge checks | ✅ 4✅ Passed checks (4 passed)

Inline comments:
In `@apps/web/src/features/block-pdf/component/PageOverlay.tsx`:
- Around line 424-431: Remove the /*`@once`*/ annotation from the anchorRef prop
in PDFPopup so it reactively updates to selectionMenuLocation().element when the
current selection changes, while preserving the existing page-matching
conditions.
In `@apps/web/src/features/block-pdf/component/placeables/TextBox.tsx`:
- Around line 92-95: Update the TextBox onBlur handler to call
markup.commands.clearActiveIf(props.id) instead of clearActive(), so only the
blurred text box is deactivated and the newly focused placeable remains active.
In `@apps/web/src/features/block-pdf/primitives/pdf-annotations.ts`:
- Around line 86-96: Update the projection effect’s thread lookup to ignore
matched threads whose comments array is empty before accessing
comments[0].commentId. Use the existing anchor.threadId early-return behavior so
commentThread is treated as absent when matchedThread.comments.length is zero,
while preserving normal projection for threads with comments.
- Around line 50-54: Update the effect that rebuilds highlights from
anchorsResource and commentThreadsResource so it preserves temporary highlights
created by beginNewHighlightCommentDrafts instead of clearing highlightsByPage
entirely. Build or update the server-backed projection separately, then merge or
overlay the existing temporary highlights while retaining the current server
highlight behavior.
In `@apps/web/src/features/block-pdf/primitives/pdf-persistence.ts`:
- Around line 18-20: Update runSave so a rejected storageServiceClient.pdfSave
is propagated or represented by an explicit failure outcome instead of resolving
as successful. In the Document.tsx autosave effect, update savedRevision only
when runSave reports success, preserving retry eligibility after failed saves.
In `@apps/web/src/features/block-pdf/signal/location.ts`:
- Line 117: Update the navigation effect around pendingParams so it consumes and
clears the pending parameters before calling goToLinkLocationFromParams,
ensuring repeated rootViewArea/updateviewarea events cannot restart the same
navigation cycle.
- Around line 599-601: Wrap the await go(location) call in the search-location
navigation flow with a try/finally, and invoke
pdf.navigation.commands.endSearchLocationNavigation() in the finally block so
the pending state is cleared on both success and failure.
In `@apps/web/src/features/block-pdf/store/comments/commentEffect.ts`:
- Around line 35-39: Memoize the active-thread membership check in
useScrollToActiveThreadEffect with a createMemo named hasActiveThread, then have
the effect use that memo instead of directly calling comments().some(...).
Preserve the existing suppression, null-ID, and scrollToCommentThread behavior.
In `@apps/web/src/features/block-pdf/util/buildModificationData.ts`:
- Line 35: Update getSaveModificationData so its bookmarks field preserves the
existing bookmarks from the document model or server snapshot instead of
assigning an empty array. Keep pdfSave’s payload flow unchanged and ensure
unrelated PDF edits retain persisted bookmarks after reload.

SolidJS Show callback child keyed non-keyed accessor @once JSX compiler annotation semantics
💡 Result:
<search_synthesis>
In SolidJS, the Show component provides conditional rendering with specific semantics regarding its children and the keyed prop [1]. Keyed vs. Non-Keyed Semantics: 1. Non-Keyed (Default): When keyed is omitted or set to false, Show monitors the truthiness of the when prop [1]. If the value changes but remains truthy, the child block is not recreated; instead, existing DOM nodes and component references are reused, and reactive updates are propagated internally [1][2]. If a function is provided as a child, it receives an accessor (a function) that provides the current value, allowing you to react to its internal changes [1][3]. 2. Keyed (keyed={true}): When enabled, Show treats the when value as a key [1]. If the value changes, the children are completely destroyed and recreated [1][2]. If a function is provided as a child, it receives the value directly (not an accessor) [1]. 3. Callback Argument Heuristic: Solid distinguishes between "accessor" children and "callback" children based on the presence of an argument [3]. A function child with an argument is treated as a callback [3]. If you provide a function without an argument, Solid assumes it is a reactive getter/accessor, which can lead to unexpected re-computation if not handled carefully [3][4]. Compiler Annotation @once: The /@once/ annotation is a JSX compiler marker used to signal that an expression should be treated as static [5][6]. 1. Behavior: It tells the compiler to opt the marked expression out of reactive tracking [5][6]. Once evaluated, it will not update when its dependencies change [5]. 2. Usage: It is typically used for performance optimization in scenarios where a value is known to be stable or when you explicitly want to prevent unnecessary reactive wrapping [5][6]. 3. Status: As of Solid 2.0, this marker is no longer part of the public JSX model [7]. Developers are encouraged to use standard reactive patterns or, if strictly necessary for one-time reads, use the untrack utility from the SolidJS core package to explicitly manage tracking outside of JSX [7]. Top results: [1], [5], [7], [3]

Keep PDFPopup anchored to the current selection.
When selectionMenuLocation() changes to another truthy object on the same page, Solid 1.9.7 reuses the non-keyed outer Show child. /*@once*/ prevents anchorRef from updating, so PopupPositioner can position the popup against the previous selection. Remove /*@once*/ so the anchor follows selectionMenuLocation().element.

Clear only the text box that lost focus.
The placeable’s on:mousedown handler activates the target before the previous textarea receives blur. The previous textarea then calls clearActive(), which clears the target’s active state. The target can become inactive and read-only until the user clicks it again.
Use the existing conditional command:
Proposed fix
- markup.commands.clearActive();
+ markup.commands.clearActiveIf(props.id);📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Guard against a thread with no comments before reading comments[0].
applyDeletedComment keeps a thread when response.thread.deleted is false, and it filters the deleted comment out (Lines 182-194). If the deleted comment was the only comment, the thread stays in the resource with comments: []. The projection effect then re-runs, matches that thread by threadId (Line 62), and reads commentThread.comments[0].commentId. That read throws a TypeError inside the reactive effect, so highlight projection stops.

Do not mark a failed save as successful.
When storageServiceClient.pdfSave rejects, runSave catches the error and resolves normally. The autosave effect in Document.tsx then runs setSavedRevision(revision) despite the failed save. That revision does not trigger another autosave until the model revision changes.
Return an explicit save outcome and update savedRevision only after a successful save. Bounded retry or backoff is not required to fix this failure; preserving the rejection or returning an explicit failure result is the necessary correction.

Consume pending parameters before navigation.
isViewerReady() subscribes this effect to rootViewArea. Each updateviewarea event reruns the effect. Because pendingParams remains set, the effect starts the same navigation again. scrollTo() can emit another updateviewarea, which can create a repeated navigation cycle.
Add a command that atomically reads and clears the pending parameters, or clear them before calling goToLinkLocationFromParams.

Preserve persisted bookmarks during autosave. getSaveModificationData sets bookmarks: [], and pdfSave sends it unchanged. The server stores this JSON in a new DocumentInstance; document loading selects the newest instance and returns its modification data. An unrelated PDF edit can therefore make existing bookmarks disappear after reload. Preserve bookmarks from the document model or server snapshot instead of sending an empty array.

Update getSaveModificationData so its bookmarks field preserves the existing
bookmarks from the document model or server snapshot instead of assigning an
empty array. Keep pdfSave’s payload flow unchanged and ensure unrelated PDF
edits retain persisted bookmarks after reload.

Annotation load can clobber server markup
High Severity
useLoadAnnotations checks hasServerSnapshot() only at the start of an async walk of every PDF page, then always replacePlaceables with extracted annotations. Document no longer passes live modificationData into this load. If hydrateFromServer runs after the check but before the final write, server-saved placeables are overwritten. When that load was started without a snapshot, the follow-up save can persist the extracted annotations and drop existing markup.

Draft threads skip auto-scroll
Medium Severity
Draft comment threads no longer scroll into view. createPdfDraftThreadId now assigns string ids, but useScrollToActiveThreadEffect still only scrolls when activeThreadId is a number. Previously the shared -1 draft id was numeric and did scroll, so a newly opened composer can remain off-screen after layout.

Summary
PdfDocumentStatesignals/stores/derivedbuckets with named document-scoped authorities for the model, persistence, tabs, navigation, viewer runtime, definitions, outline, interaction, markup, and annotationsThe production diff removes 2,596 net lines while adding focused characterization and authority tests.
Verification
nix develop --command just checknix develop --command bun run type-checknix develop --command bun run test src/features/block-pdf(16 files, 58 tests)git range-diffconfirms the 16 commits are patch-identical after rebasing onto currentorigin/mainhttp://localhost:3005/app; the available browser session redirected to the unauthenticated welcome page, so a PDF interaction walkthrough was blocked by loginNote
High Risk
Large refactor of PDF viewer state, comments, highlights, persistence, and navigation touches core editing and annotation flows across many components.
Overview
Replaces the deleted
PdfDocumentStatesignal/store/derived monolith with document-scoped authorities onusePdfDocument()(model, persistence, tabs, outline, definitions, markup, annotations, selection/share location) plus separatePdfViewerProvider(viewer pair, overlays, zoom/page, local search UI) andPdfCommentsProvider(active/selected thread, scroll suppression).Consumers across the PDF block now call those APIs instead of
pdf.state.*;TermDataStoreand TOC reducers give way topdf.definitionsandpdf.outline. Definition/reference UI resolves sections at render time viasectionReferenceMap, and definition popup state moves undersignal/definitionPopup.Behavioral tweaks: comment gutter
RightMarginLayoutmounts per page fromDocumentwith keyed threads and page layout hooks; modification autosave tracks model revision; selection popup drops the AI explanation toolbar path; navigation/hydration flows throughPdfDocumentBehaviorwith imperative go-to queued on viewer readiness.Adds characterization tests for annotations authority,
RightMarginLayoutthread stability, andSimpleSearchscoping per document.Reviewed by Cursor Bugbot for commit e79f43d. Bugbot is set up for automated code reviews on this repo. Configure here.
