- Changes panel: a working file opens in a CodeMirror editor with its diff inline (DiffEditor.tsx, @codemirror/merge, lazy-loaded); Changes folds the unchanged lines, Whole file shows them; side by side at 50/50 and full width; a Revert per block; original from HEAD or the branch's merge base (`mergeBase` on GET /git/changes?range=branch) - Every diff: green = line added whole, red = removed whole, blue = edited in place (--diff-mod) - History drawn as a commit graph (#58: `parents` on GET /git/log, --date-order; lib/commitGraph.ts) - Per-workspace never-stage list, drawn orange in the Files tree (--kept); closed Terminal rows past three deleted - Status bar plan quota for Claude (per account) and Codex (GET /api/pricing/quota, server/lib/quota.js); compact hover panel that stays open, Refresh button with a spinner - Settings → Appearance holds language, theme and pet; Ctrl+Shift+C copies; compact sidebar navigation and short session times

/**
|
||
* @file The Changes panel: the lane's code beside its console, in the five
|
||
* shapes a review actually needs —
|
||
*
|
||
* overview — every changed file, in a folder tree (JetBrains' commit view),
|
||
* with its +/- counts and its stage/discard actions; click one
|
||
* to open it
|
||
* review — every file's full diff, stacked, for reading a whole change-set
|
||
* file — one file, as a diff or as its whole content (issue #35); a
|
||
* working file is always the editor (`DiffEditor`, diffed
|
||
* against HEAD / the branch's merge base, unified or side by
|
||
* side): Changes folds the unchanged lines away, Whole file
|
||
* shows them; any other file opens on its read-only diff; a
|
||
* whole markdown file can also be read rendered (Preview), and an
|
||
* image file is shown as the picture (`GET …/git/raw`)
|
||
* history — recent commits; opening one shows that commit's diff
|
||
* browse — quick-open by path, or the repo's tracked file tree (the
|
||
* mode switcher's Files button; at full width the sidebar)
|
||
*
|
||
* and three ranges: `work` (uncommitted, what the agent has touched right
|
||
* now), `branch` (`base...HEAD`, what this lane adds on top of its base) and
|
||
* `commit` (one commit, reached from history).
|
||
*
|
||
* Only the overview polls. Review, file, history and browse are a deliberate
|
||
* read of a frozen moment — re-fetching under the reader's scroll position is
|
||
* worse than a slightly stale view, and those are the expensive shapes.
|
||
*
|
||
* Rendering lives in LaneDiffView.tsx. Every write goes through
|
||
* `POST /api/lanes/:id/git/:action`, and `discard` is asked for twice here
|
||
* before the server is told `confirm: true` — it is the one action in this
|
||
* panel git cannot undo.
|
||
*
|
||
* During a merge (issue #45) a banner offers **Complete merge** (only once no
|
||
* file is conflicted) and **Abort merge** (two clicks, `confirm: true`), and
|
||
* conflicted files get their own group with Keep mine / Take theirs / Mark
|
||
* resolved instead of stage — staging one blind would mark it resolved.
|
||
*
|
||
* A diff line's number opens a comment box (LaneDiffView `onComment`); the
|
||
* comment is pasted, as `<path>:<line> — <text>`, into the workspace's pane
|
||
* focused last (`lib/panePaste.ts`) and sent only when the user presses Enter;
|
||
* a toast says which tab took it, and a console not on screen takes nothing.
|
||
*
|
||
* An unsaved whole-file edit is never dropped silently: Back, another file,
|
||
* Cancel and a quick-open pick all ask once (`confirmDiscard`), closing or
|
||
* reloading the browser tab asks the browser's own question, and
|
||
* `onDirtyChange` tells the Workspace, which asks before closing the panel,
|
||
* switching its tab, or moving it to another workspace or session. Two-click
|
||
* actions (discard, a hunk's Undo, Abort merge) disarm after 3 s (`useArmed`).
