Per-hole stall lines gate on prior ACTIVE flow, so inside a sustained
~2 fps phase only the first hole is reported and the log goes quiet
exactly while the user suffers — the field shape (deep 15 s stretches at
2 fps) was invisible without a stats recording.
StallWatch now tracks the stretch: opened by a reported stall, fed by
every stall-sized hole while the activity gate stays broken, closed when
sustained flow returns (or a ring recreate cuts it — its holes predate
the recreate and still count). Closure surfaces one INFO line: span,
hole count, summed hole time, worst hole. One-hole stretches dissolve
silently (the stall's own line covers them), and a ≥10 s gap closes the
stretch first so a quit-to-desktop pause never folds into the tally.
