+# Implementation Plan: Mobile changes density
+
+## Overview
+
+Restore readable working-tree filenames with compact touch rows and one file
+action menu. The user explicitly requested AFK planning and implementation in
+one turn, followed by a PR with screenshots. Execute sequentially here.
+
+## Scope
+
+Change working-tree row presentation and its mobile action entry point. Keep
+Git semantics, desktop composition, file ordering, and the task toolbar intact.
+UI owns the existing reusable file-row presentation contract; no domain or
+architecture boundary changes.
+
+## Technical approach
+
+Branch `FileRow` content using the canonical responsive hook. Add a small
+touch-content component and shared DropdownMenu action surface, forwarding the
+existing callbacks. Reuse translated action labels. Keep `PanelBody` as the
+single scroll owner and existing viewport/safe-area handling. Update the public
+review guide to describe the touch menu.
+
+## ASCII UI preview
+
+UI-01: Changes tab, unstaged list, phone/coarse pointer.

+Structural requirements: basename receives available width; path/stats below;
+one visible secondary action target; menu exposes the full path; 44px touch
+targets and preserved desktop density. Pixel spacing is illustrative. Pending
+staging shows a spinner and disables its menu item. Cancel discard preserves
+the file and returns to the list. Covers AC-002.1 through AC-002.4.
+
+## Tests
+
+Existing `changes-panel-tree.test.tsx` guards tree action wiring. Update the
+existing file-row tests for touch menus, pending state, and fine-pointer phones.
+Playwright owns rendered geometry, deep-tree containment, and action routing.
+
+## E2E tests
+
+`task/mobile-changes-panel.spec.ts` (mobile-chrome) gains compact-row geometry,
+menu/action flow, and breakpoint assertions for all four criteria. Existing
+`git/git-changes-panel.spec.ts` (chromium) guards desktop staging and unstaging
+and adds the 767px/768px fine-pointer composition transition. The existing
+`git/mobile-symlink-identification.spec.ts` follows the file menu to Edit while
+retaining symlink-marker containment and viewer checks.

+- [x] [Task 01: Compact touch file rows](task-01-compact-touch-file-rows.md)
+
+## Verification results
+
+Completed: 10 mobile browser tests, 4 focused desktop browser tests, 24 file-row
+and tree unit tests, typecheck, ESLint, Prettier, staged i18n ratchet, documentation catalog,
+36 specification-linter tests, full spec lint, and diff checks passed. The
+[work order](task-01-compact-touch-file-rows.md#results) records commands, the
+baseline failure, and a temporary desktop-discovery override needed for this
+worktree's name. Four inspected screenshots use disposable E2E data and are
+published separately from the product branch.
+
+## Risks
+
+Menu close can race confirmation focus; pass the persistent trigger as anchor.
+Tree indentation and long paths must not clip touch controls. Existing mobile
+tests using inline Unstage must use the menu.

+# Task 01: Compact touch file rows
+
+## Summary
+
+Give filenames the primary width and group touch actions in one menu. Preserve
+desktop rows and the existing repository/layer-aware handlers.
+
+## In scope
+
+Touch rows, menu, pending feedback, browser regression tests, screenshots, docs.
+
+## Out of scope
+
+Toolbar redesign, Git transport, provider rows, saved preferences, new APIs.
+
+## Acceptance
+
+- Phone rows follow UI-01 and meet the geometry/action criteria.
+- Stage, Unstage, Edit, Discard cancellation, and diff opening work by touch.
+- Desktop inline actions and tree behavior remain valid.
+
+## ASCII UI preview
+
+UI-01 from the [full preview](plan.md#ascii-ui-preview):
+
+```text
+[file] status-surface-metrics.test.ts  [...]
+       apps/web/components/task +12 -3
+Menu: full path / Stage file / Edit / Discard changes
+```
+
+UI-02 desktop retains `[+] folder/name.ts  +12 -3 M` and hover actions.
+AC-002.1 through AC-002.4 require the filename hierarchy, single touch menu,
+44px targets, action parity, and unchanged desktop density.

+
+## Results
+
+- RED: the phone filename-width assertion failed at 46.7% against a required minimum of 65%.
+- GREEN: managed production build and mobile run: **9 passed**, including flat/tree geometry, 22-level tree containment, stage/unstage, discard cancellation, Edit, and layer/PR diff routing.
+- Symlink mobile regression: **1 passed**, with retries disabled. CI and the local RED run timed out waiting for the removed inline Edit button. The updated test checks the menu trigger and Edit item touch targets, marker containment, and the same file-viewer behavior. Production rendering is unchanged by this test-only follow-up.
+- Desktop: **4 passed**, including the new 767px/768px transition and existing stage/unstage pending feedback and mixed-layer scenarios.
+- The default desktop discovery excluded this worktree because its absolute path contains `mobile-`. The temporary config above scopes that exclusion to the spec basename; it changes no test behavior and was removed after the run.
+- File-row and tree Vitest suites: **24 passed**. Updated obsolete coarse-pointer assertions and covered the pending menu and fine-pointer phone presentation.
+- Review regression RED: a 22-level tree left zero filename width. GREEN: touch indentation is capped at 24px; the same browser test preserves more than half the row width for the basename and keeps status/menu contained.
+- Typecheck, ESLint with zero warnings (both components, the file-row unit tests, and both browser specs), Prettier check, and staged i18n ratchet: **passed**.
+- Catalog validation: **299 decisions and 1112 specifications**. Specification linter tests: **36 passed**. Full specification lint and `git diff --check`: **passed**.
+- Four fresh, inspected, compressed screenshots cover phone flat/tree lists, the action sheet, and desktop. Assets use disposable E2E data and remain outside the product branch.
+- Rendered hierarchy matches UI-01/UI-02. No new API, persistence, or locale keys. Public review guide updated with the menu entry point.

 From this panel you can stage or unstage files, discard working-tree changes, commit, amend, reset or revert commits, pull, rebase, merge, push, force-push, rename the task branch, choose a base branch, and create or open a pull request or merge request. Operations apply to the selected repository. Discarding a file is permanent, and history-changing operations can lose work or invalidate review; read [Git operations](git-operations.md) before using them.
 
+On phones and touch devices, working-tree rows give filenames the main space.
+Tap a filename to open its diff, or tap the row's **Show more actions** menu to
+stage or unstage, edit, or discard that file. The menu shows the full path, and
+discarding still requires confirmation. In list view, the folder appears below
+the filename; long filenames wrap.

 Changes-panel Git operations use Kandev's control path, not the agent's shell. They can work when a restricted agent mode blocks shell writes to Git metadata. If the error says that `.git/index.lock` already exists or is held, stop other Git operations and inspect the lock before retrying. Remove a stale lock only after you confirm that no Git process owns it. The Changes panel uses the same worktree, so it does not bypass an active lock. If the agent cannot create `.git/index.lock` because of its permission mode, use the Changes panel. Read [Git operations](git-operations.md#prerequisites-and-trust-boundary) before you change the agent mode.

+Provider rows retain their existing containment layout. Working-tree rows also

+
+## Touch file rows
+
+`FileRow` uses `useResponsiveBreakpoint` to choose the compact presentation
+when `isMobile || !isFinePointer`. The existing row click handler continues
+to own selection, image editing, and repository/layer-aware diff opening.
+`FileRow` splits the path once for either presentation.
+`TouchFileRowContent` renders a small file icon, a flexible filename-first
+identity button, and one 44px ellipsis trigger. List mode puts the directory
+on a secondary line; tree mode retains parent context and caps file indentation
+at 24px so deep nesting cannot consume the filename or metadata width. Long
+basenames wrap instead of ending in an ellipsis. The identity button itself
+is at least 44px tall. Inline statistics share the secondary line without
+taking space from the basename.
+
+`TouchFileRowActions` reuses the shared DropdownMenu primitives, including
+their inset phone sheet below 640px. Its label shows the full path with wrapping.
+Stage/Unstage, Edit, and Discard call the existing callbacks with repository
+identity. Menu events stop propagation so actions cannot open the diff. Pending
+staging uses the existing per-file pending flag. Discard passes the persistent
+ellipsis trigger as its confirmation anchor, outside the transient menu.
+
+This follows the mobile UI language's visible contextual menu pattern and
+the shipped `MobileChangesPanel` full-height content surface. Primary content
+stays inline because scanning files is frequent; temporary action choices
+use the existing bottom menu. No new state, persistence, scroll owner, or
+viewport container is introduced. Fine-pointer desktop composition is retained.
