- F1 [blocking]: share-modal.test.tsx + comment-content-view.test.tsx mocked
page-query without usePageMetaQuery → 3 tests threw (ShareModal uses it
directly, comment-content-view via MentionContent). Added usePageMetaQuery to
both mocks (the space-tree mocks were already fixed; these two were missed).
- F2: restored refetchOnMount:true on useGetSpacesQuery — ["spaces"] is
invalidated only by same-tab mutations (no socket path), so a cross-actor
change (an admin adding/removing THIS user from a space) left the list stale
until a hard reload. The other refetchOnMount removals (favorites/watched —
per-user, same-tab-only gap) stay removed.
- F3: corrected the trash-list + recent-changes KEEP comments — both keys ARE
invalidated (trash-list by 3 mutations, recent-changes by page CRUD), but
invalidateQueries only marks an UNMOUNTED query stale without refetching, so the
mount refetch closes the gap. The old "never invalidated" wording was wrong and
risked a maintainer deleting a live invalidation as dead code.
- F4: tests for the two load-bearing pure paths — invalidate-on-update-page (the
undefined-guard: a title-only event keeps the icon; sibling/unrelated subtrees
untouched) and breadcrumb-path-equal (equal chain → true; any id/slugId/name/
icon change or length diff → false; both-null → true). Exported
breadcrumbPathEqual for the test.
Gate: client tsc 0; the 4 affected/new test files 33 passed.

- F1: render the `underline` mark statically (StarterKit v3 enables Underline;
comment-editor does not disable it) — an underlined comment no longer degrades
the whole comment to the read-only editor fallback. renderMarks gains a
`case "underline" -> <u>`, mirroring the other marks (+ test).
- F2: keep the Open tab panel mounted (`Tabs.Panel value="open" keepMounted`)
while the heavy Resolved panel still unmounts (`Tabs keepMounted={false}`). A
per-panel keepMounted overrides the parent's `false` (Mantine 8 TabsPanel), so
an in-progress reply draft / edit in the Open panel survives an
Open->Resolved->Open switch, keeping the micro-opt of not mounting the large
Resolved list.
- F3: cover edit->save->re-render in comment-list-item.test.tsx — save calls
mutateAsync with JSON.stringify(editContentRef) and a new comment.content prop
updates the visible body; cancel restores the static body without mutating;
clearing editContentRef after cancel.
- F4: extract childrenByParent grouping into an exported pure
`buildChildrenByParent(items)` (unit-tested: nesting, orphan reply, sibling
order) + new comment-list-with-tabs.test.tsx covering the lazy reply-editor
activation (stub -> click/focus/Enter mounts the editor).

The comment panel lagged for seconds on open and stuttered on every resolve/apply
with many comments (real case: 30 open + 326 resolved ≈ 356 threads), because each
comment body mounted a full TipTap/ProseMirror editor, both tabs mounted at once,
and any mutation re-rendered the whole list.
- CommentContentView: static recursive renderer of comment ProseMirror JSON (no
editor instance) for the read-only body — supports exactly CommentEditor's node
set (doc/paragraph/text/hardBreak/mention) + marks (bold/italic/strike/code/
link), reproducing the 3-level DOM nesting for pixel-identical CSS. Unknown
node/mark or unparseable content degrades that one comment to the read-only
CommentEditor; legacy non-JSON strings render as plain text.
SECURITY: link hrefs are protocol-allowlisted (safeHref, mirroring
@tiptap/extension-link) so a stored comment with a `javascript:`/`data:` href
cannot XSS — the old TipTap read-only path sanitized this; the static renderer
must too. Control-char smuggling (java\tscript:) is stripped before the check.
- MentionContent extracted from MentionView, shared by the TipTap NodeView and the
static renderer (identical user/page-mention behavior).
- keepMounted={false} on the tabs: the inactive tab no longer mounts its editors.
- Lazy reply editor: a stub until click/focus, then the real editor (kept mounted
so the draft survives thread re-renders).
- React.memo(CommentListItem) + a childrenByParent map (replaces the per-thread
O(n^2) filter) + localized reply-send pending state: resolve/apply/reply now
re-render only the touched thread.
- Progressive first paint: useCommentsQuery no longer blocks on hasNextPage.
Gate: client comment+mention suites 22/22 passed, tsc --noEmit 0.
