 - `editor`: owns buffer lifecycle and per-buffer text, saved state, primary/selection set, modes, search, and undo/redo; session-wide clipboard policy, independent registers and owned-system fragment metadata, semantic native repeat, action metadata, command-palette and file-picker focus/dispatch, key notation, leader/count prefixes and binding resolution, modal paste policy, saving, command ownership, capabilities, and validated edit effects. Its low-level interface returns an `Invocation` when an external command is selected.
 - `files`: owns the gitignore-aware directory/file catalog, authoritative OS paths, compact tree projection, query filtering, browse/search focus, expansion/selection restoration, navigation, and scan/error state shared by floating and docked presentations.
+- `diff`: owns searchable Before/After selection, category and focus state, request freshness, read-only comparison DTOs, and aligned rows/shared vertical and independent horizontal offsets. It has no subprocess or terminal dependencies.
+- `repository`: discovers jj/Git repositories and local/advertised remote revisions, builds disk snapshots and changed-file hunks, and owns isolated temporary comparison repositories with bounded, cancellable subprocesses. It never saves editor buffers or modifies active refs/checkouts.
 - `clipboard`: owns native plain-text provider selection and bounded subprocess I/O; it never computes selections or editing offsets.
 - `syntax`: owns Tree-sitter grammar detection, per-buffer incremental trees, bundled highlight/local/injection queries, and syntax byte spans; it has no terminal color/geometry or editing dependency.
 - `markdown`: owns native Markdown link/reference resolution, local destination decoding, and heading fragment lookup through the installed block/inline grammars. It has no editor lifecycle, terminal, LSP, or external-process dependency.
 - `plugin`: owns generic document snapshots/events, zero-based grapheme positions, diagnostics, frontend-independent semantic token kinds/modifiers and completion edit/item DTOs, and versioned asynchronous update contracts. Semantic token and completion updates are native-only, not part of the Ruby wire protocol; it has no LSP protocol types.
 - `lsp`: owns opt-in native server workers, bounded framed JSON-RPC, synchronization/capability negotiation, settings, UTF-16/file-URI conversion, definition/hover results, completion decoding, and semantic token requests/legend decoding. Its private configuration resolver supplies presets without restricting language IDs.
 - `snippet`: owns bounded, frontend-independent template parsing and expansion into plain replacement text and byte-relative tabstops with per-occurrence ancestry. It never edits documents or owns input policy.
- `session`: `EditorSession` owns the editor, native LSP, and Ruby hosts together. It loads configuration once, registers eligible plugins before installing shared bindings, tracks document open/change/save/close events, polls native and plugin results, validates versioned diagnostics/navigation/completion, and retires failed plugin ownership.
+- `session`: `EditorSession` owns the editor, native LSP, and Ruby hosts together. It loads configuration once, registers eligible plugins before installing shared bindings, tracks document open/change/save/close events, polls native and plugin results, validates versioned diagnostics/navigation/completion, and retires failed plugin ownership. A cancellable diff worker owns repository I/O off the input thread; tagged results cannot reopen closed or superseded selections. Diff focus suppresses asynchronous editing/navigation effects without retiring healthy plugins.
 - `tui`: translates terminal events to session input, renders read-only active-buffer state, keeps frontend-owned viewports and syntax caches by stable buffer ID, and advertises `text`, `styled_text`, and `diagnostics` capabilities. It maps semantic tokens and diagnostics to terminal styling and has no server/protocol logic or paste acceptance policy.
 - `ruby`: evaluates configuration and runs isolated plugin hosts. Protocol, deadlines, and process cleanup stay inside this module.
 - The executable selects paths and frontend capabilities, opens an editor session, and launches the TUI.
