SAFETY-119 review: DECISIONS states the steady-meter limit

The quarter-edge numbers were measured with one cycle per reading at a
steady interval. With the default 15 s cycle floor, a meter that is
sometimes slower adds cycles on an old reading and the false alarm can
come back (reviewer's runs, 11 seeds). Text only.

+**Limits.** These runs have one cycle per meter reading, at a steady
+interval. A 20 or 30 s cycle needs `cycle_floor_s` raised; at the default
+15 s, a slower meter adds cycles on an old reading. Measured that way (11

+30 s meter on 10 (0 to 4 in 2 h, 8 to 15 without the fix); a 20 s meter on

 **Kept.** The loop in charge at its rail warns on the same cycle as before.
 The start and a restart after a stop are not hand-backs. The quarter-edge
 kick of `test_safety119.py` part 1 stays hidden (see above).
