"per-worktree ref" is an entry in the glossary.
[[def_per_worktree_ref]]per-worktree ref::
Refs that are per-<<def_working_tree,worktree>>, rather than
global. This is presently only <<def_HEAD,HEAD>> and any refs
that start with `refs/bisect/`, but might later include other
unusual refs.
And those other things are also listed as "pseudoref".
[[def_pseudoref]]pseudoref::
Pseudorefs are a class of files under `$GIT_DIR` which behave
like refs for the purposes of rev-parse, but which are treated
specially by git...
I think the motivation of special casing refs/bisect/ is to allow
use of a separate worktree for bisecting without affecting other
development or another bisection. The HEAD is singled out in the
description, but MERGE_HEAD and others (pseudoref) that are declared
here to be files under '$GIT_DIR', when we migrate fully to other
backend that may not want to have files under '$GIT_DIR' to
represent them, ought to become per-worktree, for the same reason as
HEAD should be per-worktree, i.e. it allows worktrees to be
independent from each other and have their checkout at different
commits, growing history of different branches in parallel.
