The AIUI-03 stale-response guard used ONE counter for every content:request,
so requests for different kinds cancelled each other.
useArchy.ts init fires content('all','own') and library('own') back to back.
Both sequence numbers are assigned synchronously, before either awaits, so the
first request always resolved with a stale number and was silently discarded.
Films, podcasts and this node's own files never reached the grid no matter what
the user did — only music ever arrived. Nothing logged, because discarding is
the guard working as written.
The guard is now keyed by kind+scope. Different kinds populate different grids
and cannot stale each other by definition; only a newer request for the same
grid can, which is what the guard was actually for. The existing out-of-order
test (same kind twice) is untouched and still passes.
This is the same shape as the defect 13-11 already fixed once: machinery built
and unit-tested end to end, while nothing real ever reached the UI.
