Add a frontend-only release channel picker in FieldWorks Lite Troubleshoot so preview UI can be gated without a backend flag. Empty is production (no flags); beta currently enables comments; dev shows DevContent and makes hasFlag always true.

  • hasFlag('flag-name') and <FlagContent flag="flag-name"> take names typed from CHANNEL_FLAGS. Ship by deleting the flag, not by mapping it onto production.
  • DevContent and the 5-click / enableDevMode toggle now set the dev channel instead of localStorage.devMode. That old key migrates only when no channel is already stored.
  • Comment entry points (browse badge, entry comments button, comment filters) use the comments flag instead of DevContent. The thread “mark unread (dev)” control stays behind DevContent.

Stacked on #2597 because the comments UI lives on find-comments.

Resolves #2494.

Test plan

  • Troubleshoot: empty channel hides comments UI and DevContent.
  • Type beta: comments entry points show (on a project that supports comments).
  • Type dev: DevContent and comments UI both show; leftover commentsOpen URL does not open the pane on production.
  • 5-click the logo / “Made with ❤️” sets channel to dev; 5-click again clears it to production.
  • Existing devMode=true with no channel becomes dev after reload; beta is kept if already set.
  • pnpm run test:unit -- src/lib/feature-flags/feature-flags.test.ts from frontend/viewer.

Considered and rejected

  • Listing every flag under a dev key in CHANNEL_FLAGS. That fights “hasFlag is always true on dev” and would need a map update for each new flag. dev and production stay out of the map.
  • Restoring the previous channel when turning off 5-click. Troubleshoot is the place to type beta again; remembering a prior channel is extra state.

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.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
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.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
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.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
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.

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.

Users pick a channel in Troubleshoot (empty is production). Preview UI is gated with hasFlag or FlagContent; names are typed from CHANNEL_FLAGS.

Dev mode is the dev channel: DevContent follows it, hasFlag is always true, and the old localStorage.devMode key migrates when no channel is set. Comments entry points move from DevContent onto a beta comments flag.

Resolves #2494.

📝 Walkthrough

Walkthrough

The frontend adds persisted release channels and feature-flag resolution. Development-mode state uses the new channel state. Troubleshooting exposes channel selection. Comment UI uses the comments flag. The VS Code task now uses pnpm.

Changes

Release channels and feature gating

Layer / File(s) Summary
Channel rules and persistence
frontend/viewer/src/lib/feature-flags/*, frontend/viewer/AGENTS.md
Adds channel normalization, flag lookup, development-channel behavior, storage migration, persistence, tests, and feature-flag guidance.
Reactive channel state and controls
frontend/viewer/src/lib/layout/*, frontend/viewer/src/lib/troubleshoot/*, frontend/viewer/src/locales/*
Adds reactive channel state, replaces the development store, and adds the Troubleshoot release-channel input with localization entries.
Comment feature gates
frontend/viewer/src/project/browse/*
Gates comment badges, controls, dialogs, and search filters with the comments feature flag.

VS Code development task

Layer / File(s) Summary
Development task command
.vscode/tasks.json
The Fw Lite vite task now runs through pnpm.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 48185

The release-channel migration can mishandle existing developer settings, and channel initialization can fail when browser storage is unavailable. These bounded correctness and runtime issues should be fixed before merging.

A rabbit hops through channels bright
And flags the comments left and right
Dev paths bloom, prod paths stay clear
A saved release now guides the gear

- Around line 50-56: Update the channel-loading logic around normalizeChannel
and the legacyDev migration branch so LEGACY_DEV_MODE_KEY is removed when
returning an existing stored channel, and in migration only after
setItem(STORAGE_KEY, DEV_CHANNEL) succeeds. Preserve the legacy setting if the
new storage write fails.
- Around line 45-46: Update readStoredChannel and persistChannel so they do not
use globalThis.localStorage as a default parameter; resolve storage ??
globalThis.localStorage inside each function’s try block, preserving the
fallback behavior of returning '' from readStoredChannel and swallowing storage
failures in persistChannel.

In `@frontend/viewer/src/project/browse/SearchFilter.svelte`:
- Around line 240-245: Update the filter effect around FlagContent in
frontend/viewer/src/project/browse/SearchFilter.svelte:240-245 to gate
comment-filter behavior with hasFlag('comments') and reset hasComments and
unreadComments when the flag is disabled. In
frontend/viewer/src/project/browse/BrowseView.svelte:98-100, clear the bound
unreadComments value when the badge becomes hidden, unless the consumer reset
fully handles it.

The unit (jsdom) test env under Vitest 4 leaves localStorage undefined, so
every feature-flags.test.ts case threw. Add an in-memory localStorage setup
file for the unit project.

With the tests actually running, readStoredChannel left a stale legacy
devMode key when a channel was already set; clear it unconditionally so
migration can't leave it behind.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
readStoredChannel/persistChannel resolve localStorage inside the try (its
access can throw) and drop the legacy devMode key only after the new channel
is written, so a failed write doesn't lose the migration intent.

SearchFilter clears hasComments/unreadComments when the comments flag turns
off, so hidden filters stop constraining the query after a channel switch.
