Drag-to-rebase in the DAG

• Drag a change directly onto another change to run jj rebase without looking up change IDs
• Hold-to-arm interaction reduces accidental drags and keeps single-click selection intact
• Drag hover now shows a clear target outline, node ring, and inline rebase preview
• Successful drag rebases show a toast with inline conflict follow-up and a one-click Undo action

DAG interaction polish

• Clicking a change no longer recenters or scroll-jumps the DAG unexpectedly
• The commit box is only shown for the working copy
• The Dock menu now includes Open Repository… for faster access

Internal cleanup

• Repo-level alerts, sheets, HUDs, and toasts now go through a consolidated presentation model
• DAGRow and DAGView logic moved into focused view models to keep the UI code smaller and easier to test
• Added macOS app tests for drag-rebase gesture policy and DAG row/view-model regressions, and wired them into CI via just test-app

Status bar + GitHub PR integration

• New extensible status bar with four item types: plain text, clickable link, action, and picker
• GitHub PR status via gh CLI — shows PR number, state (open/merged/closed), and checks icon for the selected change's bookmark
• Click to open PR in browser; hover to see title
• gh CLI version shown in Settings

Post-fetch cleanup for merged PRs

• After Git Pull, empty-after-rebase changes whose remote tracking was deleted are auto-abandoned
• Conflicting changes in the same situation get flagged in the toast message

Other fixes

• Toast dismiss time scales with message length (2–8s)
• Tap-to-dismiss works on the full HUD background
• CI dedup: push trigger restricted to main
• Docs: Myers → Histogram diff algorithm corrected
• types.rs split into types/ module (7 files)
• JJStatus → CliStatus, PrState/ChecksStatus enums

Diff view fixes

• Long lines no longer wrap in the unified diff — each diff line is exactly one row so the gutter and content stay aligned. Long lines scroll horizontally instead
• Row backgrounds (red/green) now fill cleanly edge-to-edge under the no-wrap layout
• Abandon Selected Lines on the working copy refreshes the diff pane correctly

Rename detection

• Batch moves (multiple files from one directory to another) are now paired correctly by filename instead of cascade-misassigning on the file list
• Empty content no longer scores as "identical" — an unrelated deletion in a batch can't steal a rename slot

Working copy auto-refresh

• Reviewing the working copy + external file save → refresh button shows the pending indicator instead of yanking your selection and scroll mid-review
• Reviewing another change + working copy change → graph silently updates so the WC entry stays current
• User actions (Abandon Selected Lines, Describe, Split, …) refresh immediately without a ghost "files changed" flash from the FS echo

Other fixes

• Repos with many files no longer stuck at loading — fixed a pipe deadlock in the LFS path probe where git's stdout filled up while we were still writing to its stdin
• Welcome view centers the logo when there are no recent repos; repo list is scrollable when long

Internal

• Diff rendering extracted into a `JayJayDiffUI` Swift package — cleaner separation between app glue (`DiffSection`, `DiffStore`) and reusable rendering primitives
• New test target on `JayJayDiffUI` with regression tests for the no-wrap alignment, background fill width, and rename batching

What's New

Image diff rendering

PNG, JPG, JPEG, GIF, WebP, HEIC, BMP, TIFF, ICO, ICNS now render as actual images in the diff view instead of <binary file> text. Side-by-side before/after for modified files; single pane for added, removed, and renamed. Pixel dimensions and file size shown under each pane. 32×32 icons render at 1:1 — no upscale-blur. Transparent regions get a checkerboard background. Diff edit mode continues to treat images as non-editable.

SVG rich-view toggle

SVG files keep the text diff by default. A small eye-icon toggle in the diff header (only shown for .svg files) switches to a rendered view via WKWebView.

DAG + file list keyboard navigation

• j / ↓ / Ctrl-n → next change
• k / ↑ / Ctrl-p → previous change
• Same bindings work in the file list when it's the active pane
• First-pane focus is the DAG on cold launch and new repo windows — no more clicking to start navigating
• Multi-window safe — only the key window's DAG responds to keys

Other fixes

• Settings → Open jj config now respects the configured editor instead of falling through to the system default
• jj fix config uses absolute paths so the formatters work regardless of which shell launched jj
• Roadmap reshuffle: added change evolution history (jj evolog), image diff, keyboard nav; removed tab-based multi-repo and bookmark drag-and-drop
• Histogram diff algorithm (via similar 3.0) — matches what jj diff produces and reads better on code than Myers

Internal

• New extensible DiffPreview enum on DiffHunk — adding PDF/video/etc. preview support is now a single enum variant + handler instead of new field pairs
• Test coverage for the image preview pipeline (is_image_path, detect_renames preview carryover, end-to-end integration test)
• update-appcast.py now prepends new entries instead of clobbering the entire file

What's New

• Myers diff algorithm — via similar crate, same as libgit2/GitHub Desktop. Cargo.lock: 15s → instant
• Divergent commit support — badge, commitId-based actions, "Abandon (resolve divergence)"
• Bookmark Manager (Cmd+Shift+B) — stats bar, filter, clean up stale/deleted, resolve conflicts
• Commit avatars — GitHub noreply + Gravatar for any email
• Scrollable commit descriptions — see full PR messages and Co-authored-by trailers
• jj-lib 0.40 + tree-sitter 0.26.8 + tree-sitter-rust 0.24.2

Performance

• Myers diff O(n*d) replaces O(n²) LCS — large file diffs are instant
• Preload all file diffs on change selection (Myers is fast enough)

Bug Fixes

• Fixed jj new/jj edit "descendants not rebased" — proper snapshot + rebase lifecycle via jj-lib
• Fixed multi-window Repository menu dispatching to wrong window (per-path handler registry)
• Fixed DAG scroll recycling with divergent commits (ForEach identity uses commitId)
• Fixed toast auto-dismiss timer not canceling on tap

What's New

• DiffStore — extracted diff caching and preloading into a proper ViewModel
• Preload diffs — first 10 files on change selection, neighbors on file click
• DiffEdit context collapsing — hides unchanged lines, shared Rust implementation
• Menu icons — SF Symbols on all menus: DAG context, Repository, Format, Help
• DAG context menu — proper separators grouped by action type
• Right-click target highlight — shows which commit "selected onto this" targets
• Clean Up Stale Bookmarks in Repository menu (fetch + prune + forget)
• Protocol-based menu system — reliable Repository menu in all window types
• Toast HUD dismisses on click
• Favicon for jayjay.hewig.dev

Performance

• DiffEdit skips reload when scrolling LazyVStack (cached state check)
• DiffEdit reuses DiffStore cache for file content loading

Cleanup

• Removed EscapeDismisser NSViewRepresentable, replaced DispatchQueue delays with Task.sleep
• Removed SwiftUI @focusedvalue system entirely, unified via ActiveRepoTracker + RepositoryMenuHandler protocol
• Unified Rust collapse_context into single collapse_context_with_mapping implementation
• Removed dead RepositoryFocus.swift

What's New

• Auto-track remote bookmarks on git fetch/pull — no more manual tracking
• Rebase selected onto context menu action for DAG
• Immutable-aware context menu — hides destructive actions (abandon, squash) for immutable commits
• Config check on repo open — alerts when user.name/user.email not set
• Working copy auto-sync — library transactions now properly sync files on disk when @ changes
• O(n) diff algorithm — prefix/suffix trimming fixes 10s+ Cargo.lock diff (was O(n²) LCS)
• Skip syntax highlighting for .lock/.csv/.svg files
• File list performance — cached reviewedPaths and buildFileTree prevent re-render lag with many files
• Redesigned Jujutsu settings — grouped sections with icons matching the Tools tab style
• Updated bookmark track syntax — uses new --remote= flag (fixes deprecation warnings)

Bug Fixes

• Fixed jj edit crash: "Descendants have not been rebased"
• Fixed jj new deleting files from target commit
• Fixed false config warning when user.name/user.email are set
