The cross-cutting substrate ranked first on the side-quest north star.
A third registry beside CommandRegistry and HookRegistry, with two
scopes (global and buffer-local), a closed scalar value vocabulary,
post-commit listeners, and no wire surface.
Ground truth established by scout at 7bc0c61, including three findings
that shaped the design:
* Tab width is five constants across two crates with two different
values -- four TAB_WIDTH = 8 in the daemon, 4 in the GPU minimap,
and no tab expansion at all on the GPU main text path. It is a
rendering-parity bug, not a config gap, so it is deferred to
stage 2 rather than made the proving adopter.
* The mode system is unwired: every editor KeymapStack::resolve
passes an empty active-modes slice. A mode scope would ship a knob
that silently never fires.
* load_user_config and set_init_complete both run inside
EditorState::new under one cfg(not(test)) block, so the
StartupOnly freeze point covers the daemon and local entry points
uniformly -- and never runs in --lib test builds.
Revision 2 records review round 1 (F1-F11). The load-bearing fix is
F1: an override is now always stored, with only value_epoch and
listener dispatch keyed on effective-value change. The prior
"equal-value set is a true no-op" reading meant an equal-valued
buffer-local override stored nothing, so a later global set would flip
the very buffer the user had pinned -- silently voiding the per-buffer
toggle this arc exists to deliver.
Also carried by revision 2: listener dispatch semantics pinned across
scopes, GC-collected listeners dropped (no MetaMethod::Gc precedent
exists), migration wrappers keep their legacy coercion, StartupOnly x
set_local rejected at define time, string-list dropped, describe's
`local` field renamed buffer_local (Lua keyword), and the direct-remove
leak corrected to permanent-but-non-aliasing since BufferIds are never
reused.
No implementation. Framing only.
