Description

Converts the unified comment edit screen from XML/View Binding to Jetpack Compose
and collapses the Activity+Fragment pair: UnifiedCommentsEditActivity now hosts
the UI directly (via setContent), since the fragment had no other host. The new
UnifiedCommentsEditScreen composable renders the four-field form (author name,
web address, email, comment) with per-keystroke validation, a Done action gated on
valid unsaved changes, and a Compose discard-confirmation dialog replacing the old
EditCancelDialogFragment. The launch intent and RESULT_OK contract are unchanged
for all three callers (rs detail, Reader, legacy detail); the ViewModel is untouched
except for one behavior fix below.

Also fixes a latent issue surfaced by the rs work: the editor gated the author
name/URL/email fields on isFromRegisteredUser, but that check keyed off the FluxC
row's authorId, which the legacy flows always wrote as 0 — so the fields were
always editable in practice. The rs detail now caches real author ids, which would
have activated that dormant gating for the first time. The fields are now always
editable, matching wp-admin and long-observed behavior.

Note: stacked on feature/rs-comment-detail-compose (#23078); the diff includes
those commits until that PR merges.

Testing instructions

Requires the RS Unified Comments experimental flag (Me → Experimental Features).

  1. RS comments list → open a comment → More → Edit
  • Change the comment text and tap Done → returns to detail, which reflects the edit
  1. Edit a comment and tap back (X or system back) with unsaved changes
  • Discard dialog appears; Discard closes without saving, Cancel returns to editing
  1. Clear the comment field, or enter an invalid email/URL
  • Inline error shows and Done is disabled
  • Author name, web address, and email are all editable for every comment
  1. Rotate the device mid-edit
  • Field text, errors, and Done state survive
  1. Airplane mode → Done
  • No-network snackbar appears
  1. Reader → a post's comments → edit a comment
  • Edit saves and reflects back
  1. Flag OFF → open a comment notification → legacy detail → Edit
  • Editor still opens and saves (third caller unchanged)

Add a Compose comments list backed by wordpress-rs, following the
postsrs/pagesrs pattern. There's no rs mobile-cache support for comments
yet, so each tab pages directly against /wp/v2/comments using the
response's nextPageParams as the cursor.

- 5 filter tabs (All/Pending/Approved/Spam/Trashed). The All and
  Approved tabs use CommentStatus.Custom("all"/"approve") because
  WP_Comment_Query doesn't recognise the "approved" value the rs enum
  serialises to
- Rows show avatar, bold "author on post" title (post titles resolved
  via a batched sparse-field request), snippet, date, pending indicator
- Pull-to-refresh, load-more, retry snackbars, shimmer/empty/error states
- Tapping a row opens the rs comment detail; the list refreshes on return
- Gated in ActivityLauncher.viewUnifiedComments by RS_UNIFIED_COMMENTS +
  site capability (WP.com REST or application password), falling back to
  the legacy list; the now-dead per-tap rs gate inside the legacy list
  fragment is removed

Batch moderation and search follow in stacked PRs.

Danger requires immutable string keys: changed copy gets a new key rather
than editing the old one in place.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- Key the post-title cache by (site, post id) so titles can't leak across
  sites, and negative-cache unresolvable ids so they aren't re-requested
  on every page load
- Set perPage explicitly on title batches (server default of 10 silently
  truncated larger batches) and fall back to the pages endpoint for
  comments left unresolved by the posts endpoint
- Discard load-more results whose fetch predates the latest applied first
  page, preventing stale pages/cursors after a silent refresh
- Offer a retry action on load-more failures and auto-advance past pages
  that dedupe away entirely, so pagination can't stall at the list bottom

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- Chunk post-title batches to the server's per_page maximum of 100;
  larger values are rejected outright with rest_invalid_param
- Always attempt the pages endpoint for ids the posts endpoint didn't
  resolve, and only negative-cache when both endpoints succeeded
- Clear negative-cached titles on user-initiated refresh so posts
  published after first sight can resolve
- Cap unattended load-more auto-advance at 3 pages and let it handle
  empty pages, not just fully-deduplicated ones
- Don't cancel/re-fire an identical in-flight title-resolve batch
- Add CommentsRsDataSourceTest covering the cache, fallback, and
  chunking behavior, plus ViewModel tests for the new paging rules

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- Cancel a tab's in-flight title-resolve job on user refresh so a job
  holding pre-clear 'not found' results can't re-apply them via the
  identical-ids guard
- Generation-stamp the negative cache so a fetch already in flight when
  the user cleared can't re-poison entries with pre-clear results
- Make the data source tests execute each request's builder lambda
  against a mocked uniffi client, asserting the endpoint, include count,
  and perPage actually sent — the chunking test now fails if chunking is
  reverted, and the posts-before-pages order is asserted, not assumed

Resolves the Android Lint code-scanning alerts on CommentsRsDataSourceTest:
SparseAnyPostWithViewContext and PostsRequestFilterListWithViewContextResponse
are pure data classes, so the tests now build real instances.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- Detail opened from the rs list backfills the FluxC cache (WP.com) and
  resolves the post title via rs, so title and like state are correct
- Detail reports RESULT_OK only when the comment changed; the list only
  refreshes then, keeping paged lists and scroll position intact
- Guard against duplicate first-page fetches; skip the retry snackbar
  when a silent refresh fails on a tab that already shows comments
- Clear isLoadingMore when a refresh replaces the list so paging can't
  stall behind the busy guard
- Stop the load-more trigger firing on the empty pre-layout list and
  re-arm it when the list size changes
- Evict all cached post titles for the site on user refresh so renamed
  posts pick up their new title
- Track COMMENT_FILTER_CHANGED on tab changes like the legacy list
- Restore the singleTop launch mode the legacy comments activity has
- Drop the dead initializingTabs bookkeeping
- Merge RsCommentListItem into RsComment (one shared type and mapper)
- Move the new unit tests to a follow-up PR to reduce this PR's size

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- Delete the now-unused ActivityLauncher.viewUnifiedCommentsDetails
- Track title-resolve jobs as a plain per-tab Job: cancel-and-relaunch
  is cheap because the data source caches resolved titles
- Drop the dead tab parameter from onCommentClick and the unused
  snackbarMessages default argument

Long-press a comment to enter selection mode, then tap rows to build the
selection. The top bar swaps to a contextual action bar offering the same
per-tab actions as the legacy list's action mode (approve/unapprove/spam/
not-spam/trash/restore/delete), with confirmation dialogs for trash and
delete-permanently and COMMENT_BATCH_* analytics.

Moderation runs the rs writes in parallel, aggregates any failures into a
single snackbar, then refreshes all initialized tabs, since moderated
comments move between them. Selection clears on tab change and after each
batch action.

Search icon in the top bar opens an inline query field (like the rs posts
list): queries are debounced 250ms with a 3-character minimum, keep the
active tab's status filter, and clear back to the normal tab content when
search closes. Selection mode is cleared when search opens or closes.

- Track and cancel in-flight load-more jobs in clearTabs(): a survivor could
  land on a reset page-generation counter and append its stale (unfiltered)
  page into fresh search results, corrupting the cursor chain
- Don't resurrect a cleared tab from the stale-load-more discard branch; the
  ghost entry blocked initTab and left the tab shimmering forever
- Keep the tab row visible while searching: the comments endpoint accepts a
  single status per request (unlike posts), so a search is always scoped to
  one tab — visible tabs make that scope explicit and switchable
- Reset each tab's scroll position when search opens, changes query, or
  closes, so replaced content renders at the top instead of clamping to the
  old offset and tripping the load-more trigger
- Use trimmed query lengths for the debounce filter and the idle/searching
  thresholds, so whitespace-only queries can't fetch the unfiltered list
- Clear results on any below-minimum query (not just blank) so the previous
  query's rows can't flash as matches for the next one
- Guard initTab against fetching during search-idle (Activity recreation or
  a late pager settle would bypass the debounce and minimum length)
- Only clear the selection on a real tab change, not the settled-page
  re-emission after recreation, and request search focus once per open so a
  selection round-trip doesn't pop the keyboard

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- Re-init the tab the user is looking at (lastTrackedTab, which follows
  every pager settle) instead of the tab captured at keystroke time; a tab
  switch inside the debounce window previously left the visible tab as a
  permanent shimmer with no fetch in flight. Removes the activeSearchTab
  field and the tab parameter from onSearchQueryChanged
- Trim and dedupe the query pipeline so whitespace-only edits neither
  restart the debounce nor refetch, and send the trimmed query to the API
- Clear displayed rows on any trimmed-query change, covering whole-string
  replacements (select-all + paste, keyboard suggestions, voice input)
  that never dip below the minimum length
- Rework the scroll reset: skip the initial emission so Activity
  recreation keeps the restored scroll positions, and skip lists already
  at the top to avoid pointless forced remeasures and fling cancellation
- Don't re-select failed batch-moderation ids into a search session opened
  while the batch ran; the untracked job outlives clearTabs and an
  invisible selection would swallow back presses and hijack row taps
- Consolidate the minimum-length policy into one isSearchable predicate
  exposed as isQuerySearchable, so the screen no longer re-derives it from
  the ViewModel's companion constant

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- Guard the failed-batch re-selection with a clear-generation counter
  instead of the instantaneous search flag: a batch run inside an
  unchanged search keeps the retry re-selection (its failed rows are
  still displayed), while any clearTabs() during the batch — search
  opened, closed, or query changed — suppresses it, closing the
  invisible-selection hole when search was opened and closed mid-batch
- Unify the search-query policy in one flow: a shared trim+dedupe
  normalization feeds an immediate on-change clear and the debounced
  fetch, so the two halves can't drift; onSearchQueryChanged shrinks to
  a plain setter. The collector no longer re-clears, so a pager settle
  that already fetched the same query inside the debounce window keeps
  its results instead of being cancelled and refetched
- Track the pager's current tab in a dedicated field instead of reusing
  the analytics dedupe key, so tracking changes can't silently retarget
  the debounced search
- Render the blank search-idle screen (not the animated shimmer) for
  tabs cleared while awaiting the debounce, removing the per-keystroke
  results/shimmer flicker; shimmer now means an actual fetch in flight
- Pass isSearchActive/isQuerySearchable to the tab screen and derive
  the idle/searching split inside it, removing the representable-but-
  impossible flag combination
- Hoist the once-per-open focus request out of SearchTopBar, dropping
  its two ferry parameters

Left behind when SearchTopBar's focus effect was hoisted to the caller.

When started with a noteId, the ViewModel refreshes the note DB after
every successful write, fires commentModerated for the notifications
result contract, edits via NotificationCommentIdentifier, and falls
back to Note.hasLikedComment() when the FluxC cache row is missing.

New fragment factory takes noteId, reply prefill and focus flags; the
result intent accumulates the NOTE_MODERATE_* extras the notifications
list uses to update the moderated note's row. Not yet reachable from
the notifications flow.

NotificationsDetailActivity's pager now hosts the rs detail fragment
for comment notes when the site resolves and the RS_UNIFIED_COMMENTS
gate (renamed to shouldUseRsComments) is on; the legacy fragment stays
as the fallback.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The notifications pager paints its ViewPager2 with a placeholder gray;
the rs detail fragment's root was transparent, so that gray showed
through inside a notification. Match the legacy comment detail and set
colorSurface on the root.

Replaces the XML/View Binding UI of UnifiedCommentDetailsFragment with a
pure-Compose screen: content, action footer with dropdown more-menu,
confirm dialogs, snackbars, and a reply box with @-mention suggestions
and a full-screen editor replacing CollapseFullScreenDialogFragment.
The fragment is now a thin ComposeView host; the ViewModel is unchanged.

Follows the legacy displayHtmlComment pipeline: emoticon smilies become

The edit screen has gated the author name/url/email fields on
isFromRegisteredUser since 2022, but the check keyed off the FluxC
row's authorId, which the legacy flows always left as 0 — so the
fields were always editable in practice. The rs detail now caches
comments with real author ids, which would have activated that
dormant gating for the first time. Keep the long-observed behaviour
(and wp-admin parity) by enabling all fields unconditionally.

The More button's weight sat on the Box that anchors its dropdown, so
the button itself wrapped content and hugged the slot's start edge.
Fill the Box so the icon centres and the ripple covers the full slot,
matching the sibling action buttons.
