Summary

Sync conflicts used to live only in Settings → Account, and auto-sync never put them on the renderer store. This is the last Inkdrop-gap item (D.10): one screen, three actions.

  • Modal in the main window (still available inline in Settings)
  • Keep this device / Keep other / Open both (saves {title} (remote), keeps local, opens both windows)
  • Auto-sync sync-success now carries conflicts so the screen actually appears
  • Footer and header say Review, not “resolve in Settings”

Does not start a new sync engine.

Type of Change

  • New feature

Checklist

  • Tests pass locally (pnpm --filter desktop exec vitest run on the new files + renderer utils)
  • Typecheck and eslint on the touched files
  • PR targets develop

Summary by CodeRabbit

  • New Features

    • Added a sync conflict review screen with side-by-side and unified comparison views.
    • Users can keep either version, dismiss conflicts, or open both versions as separate notes.
    • Sync indicators now show conflict counts and provide a Review action.
    • Added responsive layouts, keyboard controls, progress states, and error feedback.
  • Documentation

    • Updated the shipped features list to include the new sync conflict workflow.
  • Tests

    • Added coverage for conflict handling, merging, title formatting, and opening both versions.

Conflicts were buried in Settings, and auto-sync never
handed them to the renderer. One screen, three actions:
keep this device, keep other, or open both.

Warning

Review limit reached

@tomymaritano, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 46 minutes

Limit details: You’ve used the included review currently available.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits within each organization.

For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The sync pipeline now reports conflicts to the renderer. The store preserves and tracks conflicts. The desktop app provides modal and inline resolution views with actions to keep either version or open both.

Changes

Sync Conflict Resolution

Layer / File(s) Summary
Sync conflict reporting and state
apps/desktop/src/main/services/sync/SyncService.ts, apps/desktop/src/main/services/sync/types.ts, apps/desktop/src/renderer/stores/syncStore.ts
Sync success events include conflicts. The store merges conflicts by noteId and tracks conflict-screen dismissal.
Conflict utilities and actions
apps/desktop/src/renderer/utils/conflictCopy.ts, apps/desktop/src/renderer/utils/openBothConflict.ts, apps/desktop/src/renderer/utils/__tests__/*
Utilities format conflict titles and queues, merge conflicts, detect new conflicts, and create remote copies. Tests cover success and failure paths.
Single-conflict resolver
apps/desktop/src/renderer/components/sync/ConflictResolver.tsx, apps/desktop/src/renderer/components/sync/ConflictResolver.module.css
The resolver supports modal or inline display, side-by-side or unified diffs, dismissal, errors, and three resolution actions.
Desktop conflict entry points
apps/desktop/src/renderer/App.tsx, apps/desktop/src/renderer/components/sidebar/SidebarFooter.tsx, apps/desktop/src/renderer/components/sidebar/sidebar.module.css, apps/desktop/src/renderer/components/sync/SyncStatusIndicator.tsx, docs/NOW.md
The app mounts the resolver. Sidebar and status indicators show conflict counts and open Review. The shipped list documents the flow.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟠 High · up to 2c6e0

The conflict screen can mishandle the core “Keep this device” action by preserving remote content instead of the local version, while “Open both” can report success after a failed rename and leave duplicate copies. Modal accessibility and responsive interaction gaps also remain, so the PR is not merge-ready until these issues are fixed.

Inline comments:
In `@apps/desktop/src/main/services/sync/SyncService.ts`:
- Line 613: Update the conflict flow involving resolveConflict,
applyRemoteChange, and resetSyncTracking so resolving with “local” preserves and
queues the original local note rather than the already-overwritten remote
content. Keep the local note at noteId until resolution, or carry its copy ID
through SyncConflict and restore that copy before resetting sync tracking.

In `@apps/desktop/src/renderer/components/sync/ConflictResolver.module.css`:
- Around line 166-181: In the .content and .diffContent styles, replace the
deprecated word-break: break-word declaration with overflow-wrap: anywhere,
preserving the existing wrapping behavior.
- Around line 259-268: Update the mobile breakpoint styles for .dialog or
.content so stacked panes remain usable in short windows: either enable vertical
scrolling within the dialog body or reduce the stacked panes’ minimum height
below the current 160px. Keep the action rows reachable inside the dialog while
preserving the existing desktop layout.

In `@apps/desktop/src/renderer/components/sync/ConflictResolver.tsx`:
- Around line 117-131: Update ConflictResolver so the heading id is derived from
both variant and note id, and reference that same unique id in the section’s
aria-labelledby attribute. Preserve the existing modal and inline behavior while
ensuring simultaneously rendered resolvers never share an id.
- Around line 230-236: Update the conflict modal rendering around the overlay
and inner wrapper in ConflictResolver to manage focus: focus the dialog when it
opens, save the previously focused element, keep Tab and Shift+Tab cycling among
focusable elements inside the dialog, and restore the saved focus target when it
closes. Preserve the existing click and keydown propagation behavior while
adding the required dialog semantics and focus cleanup.

In `@apps/desktop/src/renderer/components/sync/SyncStatusIndicator.tsx`:
- Around line 100-111: Add an accessible name to the conflict action element in
SyncStatusIndicator by applying aria-label={label} when it is rendered as a
button, preserving the existing conflict click and keyboard behavior.

In `@apps/desktop/src/renderer/utils/__tests__/conflictCopy.test.ts`:
- Around line 45-48: Update the “keeps unresolved when incoming is empty” test
for mergeConflicts to assert reference identity, using the existing array as the
expected value rather than only structural equality; preserve the current
empty-incoming behavior.

In `@apps/desktop/src/renderer/utils/__tests__/openBothConflict.test.ts`:
- Around line 44-54: Add a test for the getNote failure path in
openBothConflict, using a getNote mock that returns { ok: false } and asserting
createNote receives notebookId: undefined while preserving the expected
conflict-resolution flow.

In `@apps/desktop/src/renderer/utils/openBothConflict.ts`:
- Around line 31-42: Update the flow in openBothConflict so the created copy is
resolved immediately after successful createNote, preventing retries from
creating duplicates. Handle both updateTitle returning ok: false and updateTitle
rejecting by reporting the rename failure, and only open the copied note with
copyTitle after a successful title update.

Pull overwrote the note with remote before the user picked a
side, so Keep this device queued the wrong version. Restore
the captured local body, and tighten the conflict dialog.
