Struct BufferFlags 

pub struct BufferFlags {
    pub listed: bool,
    pub hidden: bool,
    pub ephemeral: bool,
}

Vim-style per-buffer flags (DESIGN.md §5.9). The shape is fixed now so additions don’t churn every call site; v1 ships with listed populated (:bn / :bp / :ls skip unlisted buffers once the wiring lands) and hidden reserved for “keep loaded without a window” semantics. Both default to “normal buffer” (listed = true, hidden = false).

Fields

listed: bool

Whether the buffer appears in :bn / :bp / :ls. Vim’s “unlisted” buffer (:setlocal nobuflisted).

hidden: bool

Whether the buffer stays loaded even when no window shows it. Vim’s 'hidden' option per buffer. v1 doesn’t gc on pane close, so this is informational; future cleanup passes will read it.

ephemeral: bool

Transient popup-backing buffer. Stronger than listed: false — an ephemeral buffer is invisible to :ls ENTIRELY (not just shown with a u marker like an unlisted buffer), never appears in :bn / :bp, and is garbage- collected when its owning popup dismisses. Used by content popups that join the registry to render through the compose seam (completion docs today; hover/signature already ride the floating-popup slot). Default false (a normal buffer).

Slice: PU.5.
