Struct MinibufferFocus 

pub struct MinibufferFocus {
    pub focused_buffer: BufferId,
    pub prior_buffer_id: BufferId,
    pub prior_active_buffer: BufferKind,
    pub prior_cursor: Position,

MB.1 / MB.5a (rich minibuffer): the editing state suspended while a minibuffer prompt (: command line or /·? search line) owns self.document. When a prompt opens, [Editor::focus_editing_buffer] swaps self.document / document_buffer_id / active_buffer to the synthetic *command-line* / *search-line* buffer and stashes the prior editing focus here without touching the pane tree (the active pane keeps rendering its own buffer). [Editor::restore_editing_buffer] pops it back on submit / cancel. Some(_) is the “a prompt is focused” flag; whether it’s the command line vs the search line is decided by Editor::search_line (command_line_active / search_line_active). Prompt-agnostic by design so git-commit-line / repl-input reuse it unchanged (design §6).

Fields

focused_buffer: BufferId

FS.1b: the buffer this frame FOCUSED — the surface itself, not what it took focus from.

It is what lets a focus tell “I am nesting inside the thing that has focus” from “I am REPLACING it”. A prompt opening while a prompt is focused is the second: two frames would mean two restores, and the first <CR> would land the user back in the previous prompt instead of their file.

prior_buffer_id: BufferId

The document buffer that was focused for editing before the : line took over. Restored (re-fetched from the registry by id) when the command line closes.

prior_active_buffer: BufferKind

Kind of the prior active buffer (Document / Messages / …).

prior_cursor: Position

Cursor in the prior buffer at focus time.

prior_scroll: u32

Scroll (first visible line) of the prior buffer at focus time.

prior_leftcol: u32

Horizontal scroll of the prior buffer at focus time.

prior_modal: ModalState

Modal state at focus time, restored on close.

expanded: bool

MB.2: whether the : line is expanded into the full-modal mini-buffer band (<C-x><C-e>). Tier 1 (false): the one-row readline : line under ModalState::Command. Tier 2 (true): the same *command-line* surface grown in place with the full vim grammar (real Normal / Insert / Visual). Collapsing returns the edited text to the one-row line for review.
