Enum FirePass 

pub enum FirePass {
    All,
    HooksOnly,
    DecosOnly,
}

Which callbacks a walk over placed geometry (crate::fire_hooks and the helpers it shares with page_break_core) is allowed to invoke.

Upstream fires both halves in ONE pass, from ops_of_evaled_vert_box_list (handlePdf.ml:336 for EvVertHookPageBreak, :325 for EvVertFrame’s deco), and that pass runs per page INSIDE the page loop — page N’s body callbacks before page N’s own pagepartsf. That ordering is load-bearing: stdjareport’s \figure is a hook-page-break that pushes the figure onto a let-mutable list which the page-parts callback drains onto a LATER page, so a hook that fires after the loop registers into a list nobody reads again.

This port cannot fire both halves there, because a decoration’s rect needs the frame’s per-page top/bottom EXTENT, which is only known once the page’s header and footer are placed and the page is complete. So the walk runs twice: page_break_core drives a FirePass::HooksOnly pass per column (upstream’s position, pageBreak.ml:747-748), and the post-run fire_hooks drives a FirePass::DecosOnly one. Each callback still fires exactly once.

Variants

All

One undivided pass — every hook and every decoration. What a hand-built DocumentValue handed straight to fire_hooks gets.

HooksOnly

hook-page-break closures only. Frame decorations are skipped, but the walk still descends through frames, tabular cells and graphics runs, so a hook nested in one of them fires here and nowhere else.

DecosOnly

Frame decorations, GraphicsElem::Destination markers and everything else the walk records — but not one hook-page-break, which the preceding FirePass::HooksOnly pass already ran.
