Now users can easily find unread comments:

there's also some new filters:

clicking the badge above toggles on the unread comments filter.

When filtering to unread comments, the comments drawer/sidebar is opened automatically when you click an entry.

Also fixed an issue where on mobile the last few fields were hidden under the drawer, this was done by changing from a drawer to a resizable area, but styled as a drawer now.

This means that the side bar is now resizable too!

side quest. Fixed an issue with really long words where they would push stuff off screen (entry header) and just generally cause problems (preview and entry row just overflows off the page)

AI summary

Three commits on top of develop, all around unread comments in FW Lite:

Gridify filter (4f677bf) — adds CommentThreads / UnreadComments query support so entries can be filtered by whether they have comments, and whether those comments are unread.

Dev-only mark-unread (141295e) — marking a thread read was a one-way door, which made testing unread handling awkward. Adds MarkCommentThreadUnread(Guid threadId) down the stack:

  • LocalCommentReadStatusService.MarkThreadUnread collects the thread's comment ids and re-inserts them via the existing MarkCommentsUnread.
  • Declared on IMiniLcmWriteApi (default throws, matching its MarkCommentThreadRead sibling), implemented in CrdtMiniLcmApi, forwarded through the validation and normalization wrappers, and exposed as [JSInvokable].
  • The viewer gets a mark-unread button on each comment thread, gated behind DevContent so it only shows in dev mode. Labels are intentionally not $t-wrapped since it is a debug control.

Browse view filter toggle (c817375) — surfaces the project-wide unread count next to the sort menu as a toggle chip (UnreadCommentBadge) that filters the entry list to entries with unread comments, plus Has comments / Has unread comments switches in the filter popover. The chip is a bits-ui Toggle, so it carries aria-pressed / data-state and reads as on/off rather than as a button that flips a boolean; the count sits in the chip with the full plural string in the tooltip and aria-label, because the master column is too narrow for the long label.

Test plan

  • LcmCrdt.Tests CommentTests.ReadStatus* — 8 tests pass.
  • pnpm run check in frontend/viewer — clean.
  • Manual: browse view in the demo project, verified the chip's off/on states, that hover no longer picks up the primary color, and that the view-options trigger stays pinned to the end of the row. Verified with the demo api temporarily reporting a non-zero unread count (reverted before commit).
  • Not covered: the dev-only mark-unread button and the gridify filter were not exercised against a real CRDT project with unread comments.

Marking a thread read is easy to trigger but there was no way back, which
made testing unread handling awkward. Adds MarkCommentThreadUnread through
MiniLcm -> CRDT -> JSInvokable, plus a mark-unread button on each thread
gated behind DevContent.

Surfaces the project's unread comment count next to the sort menu as a
toggle chip that filters the entry list down to entries with unread
comments, alongside a 'Has comments' / 'Has unread comments' pair in the
filter popover.

📝 Walkthrough

Walkthrough

The change adds CRDT comment-query mappings, unread-thread APIs, and viewer controls for filtering entries by comments. It also adds debug-only unread-thread actions, browse sidebar state, localization entries, and tests.

Changes

Comment filtering and unread state

Layer / File(s) Summary
Comment query mappings and filtering
backend/FwLite/LcmCrdt/Data/*, backend/FwLite/LcmCrdt/*FilterMapProvider.cs, backend/FwLite/LcmCrdt/LcmCrdtKernel.cs, backend/FwLite/MiniLcm/Filtering/*, backend/FwLite/LcmCrdt.Tests/MiniLcmTests/*
The CRDT query mappings expose comment threads and unread comments. Gridify maps these properties to entry filters. Tests cover unread-comment queries and entry filtering.
Unread-thread API propagation
backend/FwLite/MiniLcm/IMiniLcmWriteApi.cs, backend/FwLite/MiniLcm/Normalization/*, backend/FwLite/MiniLcm/Validators/*, backend/FwLite/LcmCrdt/*, backend/FwLite/FwLiteShared/Services/*, frontend/viewer/src/lib/dotnet-types/generated-types/*, frontend/viewer/src/project/demo/*
MarkCommentThreadUnread now passes through the write API, validation and normalization wrappers, CRDT read-status service, JavaScript invokable interface, and demo API.
Viewer filters and comment controls
frontend/viewer/src/project/browse/*, frontend/viewer/src/project/browse/filter/*, frontend/viewer/src/lib/entry-editor/comments/*, frontend/viewer/src/lib/utils/search-params.ts, frontend/viewer/src/locales/*.po
The viewer adds comment and unread-comment filters, an unread badge, query-parameter sidebar state, and a development-only “Mark unread” control. Localization catalogs add related messages and metadata cleanup.

Estimated code review effort: 3 (Moderate) | ~30 minutes

Merge Risk: 🟡 Moderate · up to 55223

The change adds unread-comment filtering and a development-only mark-unread control, but comment functionality is currently hidden from normal users when enabled, and Reset can leave comment filters active and produce incorrect browse results. Focused tests also need scoping to avoid order-dependent assertions, so the PR is not merge-ready until these bounded issues are addressed.

Poem

I’m a rabbit with comments to mark,
Unread threads now glow in the dark.
Filters hop into view,
Tests check what is true,
And the browse pane opens its arc.

Enabling the unread-comments filter now opens the comment sidebar, so the
comments you filtered for are visible without a second click. It opens only
on the off->on transition, so closing the sidebar keeps it closed while you
click through entries.

The open state moves from EntryView-local state to a commentsOpen query
param, which makes it deep-linkable and survives reloads. The param is
replace-only: the mobile sidebar is a vaul drawer that pushes its own
history entry for back-to-close, and pushing ours as well left a stray
entry that re-opened the comments on a second back.

Also only render the comment filter controls when the project supports
comments.

The inset is a flex item with the default min-width:auto, so it could not
shrink past its content's min-content width: any content wider than the
space available pushed the whole page past the viewport, and closing the
sidebar handed back exactly the 256px it was short.

Measured at a 1280px viewport with a 1400px-wide element in the entry
editor: the inset rendered 1280px wide (256px of overflow) instead of the
1016px available. With min-w-0 it stays at 1016 and the over-wide content
clips inside the entry's scroll area.

Below xl the comment panel was a vaul drawer, which is position:fixed and
so covered the entry rather than sharing space with it. At the default
snap on a 375x812 viewport it hid the bottom 447px of the entry's scroll
area, and since the scroll area was sized to the full detail height that
content stayed unreachable at maximum scroll.

Entry and comments now live in a ResizablePaneGroup: side by side at xl
and above (where the panel was a fixed 360px aside), stacked below it.
Both panes are always fully visible and the split is draggable.

The stacked layout uses a new grab-bar variant of the resize handle, a
thumb-sized strip with a drawer-style pill, in place of the hairline
divider.

CanQueryThreadUnreadComments read whichever thread came back first from the
shared fixture's database, and CanQueryEntryUnreadComments asserted a count
over every entry in it, so both depended on what earlier tests in the class
had left behind. Scope each to its own records.

Reset also left the comment switches on, keeping their Gridify predicates in
the filter and userFilterActive true.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The grab bar took a 24px row of its own above the panel header, so the
chrome between the entry and the comment list ran to 81px. The stacked bar
is now just the 1px rule at the pane boundary, with its grip sitting in the
header row below, centred between that header's leading and trailing
buttons. The grip carries a padded hit area so it stays thumb-sized.

Dropping the handle's horizontal margins also stops the rule overhanging
the pane group, which had been pushing the grip off centre.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The headword h2 was an inline element in a justify-between row with nothing
to constrain it, so a single unbreakable word set the row's min-content
width and pushed the actions past the edge: at a 900px viewport the h2 ran
to x=1268 and the buttons sat beyond it, ~450px off screen.

Truncate the headword instead, with the full text on the title attribute,
and stop the actions shrinking.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
A headword with no break opportunity overflowed both the list row and the
preview card. overflow-wrap alone does not help there: it does not reduce
an element's min-content width, so the ancestors were still stretched by
the word - the list row's text measured 813px inside a 357px row.

So each place needs both halves: min-w-0 on ListItem's content wrapper and
on the row's headword so the chain can shrink, then wrap-break-word on the
headword itself. break-all was the first thing tried and reads badly, since
it breaks ordinary words mid-word at the container edge.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The pane group only existed inside the comments-open branch, with the entry
column rendered from a snippet in both branches. Rendering the same snippet
at two positions in the tree reuses nothing, so opening or closing comments
tore down the editor and rebuilt it, losing scroll position and any
in-progress editor state. The key on the split direction did the same on
every breakpoint crossing.

Always render the group and the entry pane, and make only the handle and
comments pane conditional, the way MasterDetailView keeps its master pane
mounted while the detail toggles. MasterDetailView needs IfOnce because its
master gets hidden on mobile; the entry pane is never hidden, so a plain
pane is enough. Paneforge tracks direction reactively, so the key can go.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
CommentDialog picked between an inline panel, a bottom drawer and a side
sheet, but its one caller has always passed inlineSidebar, and the drawer
layout is gone now that entry and comments share a resizable split. Remove
both dead branches along with the imports, the inlineSidebar prop, and the
title they rendered - which also makes subjectName dead, since the visible
header comes from CommentPanel.

Re-extracted the locale catalogs: the "Comments for {0}" title is gone and
the source references drop CommentDialog.
