Subject: [PATCH] feat(chat): open agents' plans, to-dos and edits in a Work
 panel

What an agent hands the person to look at - a plan to approve, a to-do
list, an edit - reached the chat as 400 characters of JSON behind a
collapsed tool row. Each tool call's own input is now read in main into a
bounded SessionMessage.artifact, for Claude (ExitPlanMode, TodoWrite,
TaskCreate/TaskUpdate, Edit, MultiEdit, Write), Codex (update_plan,
apply_patch, the FileChange items code-mode patches complete with, the
exec stream's todo_list and file_change) and Copilot (exit_plan_mode,
edit, create, apply_patch), plus ACP plan updates and diff content.

The renderer folds them into a Work panel beside the transcript: Plan
(every version, flagged while it waits for approval), To-dos (where the
list stands now) and Edits (per file, each change as its call described
it, with a link to Changes for what is on disk). A row that carries one
opens the panel at itself in one click; the header's Work key and cmd+J
open it on what matters now. Under 720px of deck the panel covers the
conversation instead. A plan gate's approval card now shows the plan.

A call whose result failed is marked on its own row, matched by tool-use
id, so an edit that never landed reads as one. Codex's streamed
file_change rows are named as their logged FileChange rows are, so a
rejoined turn matches the two.

@@ -60,6 +60,7 @@ Performance invariants — all deliberate, keep them:
 
 - The full index is never shipped to or rendered by the UI. Always paginate.
 - Meta parsing reads at most 256KB per file. Parsers are failure-tolerant: session log formats are provider-internal and drift between releases, so skip anything unreadable rather than fail the scan.
+- What a tool call hands the person — a plan, a to-do list, an edit — rides its transcript row as `SessionMessage.artifact`, read off the call's own input in main by `src/main/parsers/artifacts.ts` (shared by the three parsers and the stream parsers in `chat.ts` and `acp-core.ts`) and bounded there (files per call, lines per file, line width), because it crosses IPC on every transcript read. A call that failed is marked on its own row (`failed`), matched to its result by id where the log has one. The renderer only folds these for the Work panel (`work.ts`); it never parses tool JSON.
 - A parser reports only what its log states (`SessionMeta.logBranch`), never what the disk says. Anything derived from the checkout — `repo`, `isWorktree`, `gitBranch` — is the indexer's `annotate()`, is recomputed on every scan, and is stripped before the stat-cache is written so a renamed remote or a moved worktree can't freeze into it. Branches are the live example: Copilot stopped writing `context.branch` after CLI 1.0.80 and most Codex rollouts carry no `git` block, so for those the checkout's HEAD is the only source.
 - A session can span several files: Codex paginates a long thread into a new rollout whose `session_meta.history_base` names where the previous one's history ends. The parser reports that (`SessionMeta.historyBase`), `foldThread` in the indexer folds every file carrying one id into a session on the newest file with the earlier ones as `segments`, and anything that reads or removes a session's log — transcript, search, profile, cleanup — reads every file (`sessionLogFiles`; an earlier page only up to its `endByte` where the thread's history is what counts), never `sourcePath` alone. Only liveness reads just the newest file, the one being written.
 - The stat-cache (mtime+size, persisted to userData) means restarts only re-parse changed files; scans yield to the event loop so IPC never blocks.

A `role=separator` whose value is the rail's *measured* width; ← → move it 16px (64 with ⇧), Home/End reach the bounds, double-click resets.

Settings, Agents, Profile and Cleanup all use it. **A tab replaces the panel; nothing in a card scrolls to a heading further down** — a jump row that scrolled took the title, the row and Close off screen with it, and a card of stacked sections read as one long page. Switching mounts the panel fresh (two panels built alike must never share internal state) and puts the card's scroller back at `scrollTop 0`. The row is one tab stop (roving `tabIndex`; ←/→ wrap, Home/End), only the selected tab carries `aria-controls`, and the panel is named by its tab — so a panel holding one group carries no heading that repeats the pill, and a panel holding several names each group with an `h3` that doesn't either. A tab may carry its count (`.pnl-pill-n`, left off at zero), a warn tone or an amber dot. Controls that govern every tab (Cleanup's threshold, Agents' scope, Profile's headline numbers) sit above the row; the pill row must hold in two rows at the 560px floor. A new card view that grows past a screen gets tabs, not a jump row.

+- **Beside, not instead of.** Under the header the chat is a row, `.chat-deck`: the

+  and the panel (`clamp(300px, 38%, 460px)`, hairline left border, `--pane`). The deck is
+  a `container: chat-deck`, and under 720px of it (the panel's 300px floor beside ~420px
+  of conversation) the panel covers `.chat-main` instead, on solid `--bg` — the way
+  Changes takes the transcript's place. Asked of the deck, never the window: the rail is
+  dragged. Changes (header, ⌘D, or the Edits tab's link) closes a panel that covers the
+  conversation first — it would otherwise open unseen behind it; beside the
+  conversation the panel stays, so what the agent said and what is on disk read side
+  by side.
+- Opened by the header's **Work** key (`.btn-review.btn-work`, `aria-pressed`, ⌘J —
+  offered only once the transcript carries something for it) on the tab that matters
+  now (`defaultTab`: a plan waiting for approval, else a list still under way, else the
+  edits), or by a `.tool-open` row at that row. Opening moves focus to the selected tab;
+  Escape (or the ×, `XIcon`) closes it and hands focus back to what opened it. It closes
+  when the session's directory changes, like review.
+- **Tabs** are the card tabs (`TabList`, `.pnl-pill`) without the card's rule under
+  them: **Plan** (amber dot while a plan waits for approval), **To-dos** (count = steps
+  not done), **Edits** (count = files). The body (`.work-body`) is the panel's one
+  scroller, `tabIndex=0` so a keyboard reaches it, and goes back to the top on a tab
+  switch. Each tab leads with a `.work-meta` readout in the mono voice; an empty tab
+  says, in one sentence, what would appear there (`.work-empty`).
+- **Plan**: the plan's markdown at `--fs-prose`. Earlier versions are one step away
+  (`Earlier` / `version 2 of 3` / `Later`, `.btn-ghost.small`); a row opens its own
+  version. `waiting for your approval` (`.work-flag`, warn) while it is the pending ask.
+- **To-dos**: an `<ol>` of `.work-todo` rows, the state as a shape (`TodoMark`: ring,
+  ring with a dot, ring with a check) *and* an `sr-only` word; the step under way wears
+  an accent tint, done steps dim their text. `todos` artifacts replace the list; Claude's
+  `TaskCreate`/`TaskUpdate` fold into it by task number.
+- **Edits**: `N edits · M files` + `DiffStat`, then a `.work-note` that the edits are as
+  the calls described them — with a `Changes` link to the worktree's real diff where
+  there is one. Files are review file blocks (`.idiff.review-file.work-file` in an
+  `.idiff-list`), open by default while there are three or fewer (files that arrive
+  mid-turn follow the same default; only what the person toggled is remembered); each edit under an
+  `.idiff-rail` (time · tool, `didn't apply` in warn when the call failed), its hunks in
+  the shared `DiffLines` grammar, unified only. A row that opened the panel opens its
+  file and rings its edit (`.work-edit.ringed`, an accent inset) for two seconds.
+
 ## Permission prompt (`PermissionAsk`, `.perm-card`)
 
 A turn Cockpit drives over ACP can stop mid-turn and ask (`session/request_permission`).

+## Plans, to-dos and edits: the Work panel
+
+Agents hand you things to look at while they work: a plan to approve, a to-do list they
+tick off, and edits to your files. Cockpit reads each of them from the agent's own tool
+calls and opens them in the **Work** panel beside the conversation. The panel has three
+tabs:
+
+- **Plan**: the plan the agent proposed (Claude Code's plan mode, Copilot CLI's
+  `exit_plan_mode`), rendered as a document. If the agent revised it, **Earlier** and
+  **Later** step through each version. While the plan is waiting for your approval, the
+  tab says so.
+- **To-dos**: the agent's list as it stands now: Claude Code's tasks (or its older
+  `TodoWrite` list), Codex's plan, or an ACP agent's plan. Each step shows as not
+  started, in progress or done.
+- **Edits**: every file the agent changed, in the order it first touched them. Each change
+  appears the way the call described it: a Claude `Edit` or `Write`, a Codex or Copilot
+  patch, a Copilot `edit` or `create`. An edit whose call failed is still listed, marked
+  **didn't apply**.
+
+A tool row that carries one of these is a single click: the row names the plan, the list's
+progress or the files and their `+`/`−` counts, and clicking it opens the panel at that
+item. The header's **Work** key (⌘J) appears once the conversation holds any of them. It
+opens the panel on whatever matters now: a plan waiting for you, else a list still in
+progress, else the edits. Escape closes the panel and returns you to where you were.
+
+When the window is too narrow to hold the conversation and the panel side by side, the
+panel covers the conversation until you close it, the same way **Changes** does.
+
+::: tip What the agent said, and what is on disk
+The Edits tab shows what each call *said* it changed. [**Changes**](/guide/worktrees-and-prs)
+(⌘D) is the worktree's own diff, which is the record of what is actually on disk. A Codex

+the session once the turn ends to read the lines from its log.

+
+Copilot CLI keeps its to-dos in a database of its own rather than in its log, so a
