Unclear Whether the tengu_quiet_dolphin gate that guards this plugin form of the diff panel is enabled has not been read for this release.

What

A new internal plugin now describes the /diff panel, the view showing changed files and their edited sections (hunks) beside the transcript, as a plugin-based pane that refreshes as Claude makes edits, rather than being wired in as fixed built-in UI.

Why

This is a structural change in how the /diff panel is implemented internally; it doesn't change what /diff shows you.

Added since A small documentation edit on Fullscreen rendering touched a line naming /diff after this was published.
