📝 Walkthrough

Walkthrough

The PR pane now uses manually persisted per-chat state. Webhook-driven auto-population, delta detection, animated delta banners, and field pulses were removed. Draft surfaces no longer create pane state, and chat and terminal tests cover the updated behavior.

13465-13477: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Fix the pane-reserve comment: it names the wrong pane and the wrong side.

This comment says prPaneOpen persistence would cause "a 276px left gutter" without the sessionSurfaceMounted gate. Check computePaneReserve: it always returns left: "0px", and its 276 reserve (PANE_RESERVE_RIGHT_PX) applies only to right, driven by chatActionsFloating (from chatActionsOpen), not by prPaneOpen. The sentence two lines above this edit already states that the PR pane is a fixed overlay that never reserves gutter space, which contradicts the added sentence.

Update the comment to attribute the stale-reserve risk to chatActionsOpen (persisted per chat, same as prPaneOpen) and to the right-side reserve, not the PR pane and not the left side.

Removes the webhook-driven auto-pop of the floating PR pane on both the
ADE chat surface (AgentChatPane) and the CLI session surface
(WorkViewArea). The pane now opens only via an explicit toggle and,
because per-chat companion state persists as before, an opened pane
stays open across chat switches and restarts until closed.

- useChatPrAutoPop -> useChatPrPaneOpen: drops the prs.onEvent
  subscription and the getForLane baseline seed; keeps the hydrate/
  persist effects and their stale-flush guard intact.
- ChatPrPane: removes delta detection helpers, the transient delta
  banner, FieldPulse flashes, and their now-unused imports.
- Tests: persistence suite kept; pop/delta suites removed;
  WorkViewArea pin-routing assertions moved onto the pane props.
- Gate the chat header PR-pill pane toggle on a selected session so the
  draft/new-chat surface falls back to the toolbar's inline PR menu
  instead of persisting open state for a pane that cannot render there.
- Drop dead window.ade save/restore + clearAllMocks scaffolding from the
  renamed hook's test file.
- Refresh docs (composer-and-ui.md, pull-requests/README.md) and the
  companion-state field comment for the no-auto-open behavior.
Clicking the header PR pill on the draft surface must not persist
prPaneOpen=true under the draft companion key — the pane cannot render
there, so the pill falls back to the inline menu instead. Fails against
pre-gating code, passes after.
CodeRabbit: computePaneReserve reserves right-only from chatActionsOpen;
the comment wrongly attributed the 276px gutter risk to the PR pane and
the left side.
