+#
+# ⚠️ RAISED 30 s -> 150 s on 2026-09-05, and the reason is a REGIME CHANGE, not a
+# change of mind about the alarm. 30 s was the planning cadence (2.3), chosen
+# when a loop-side engagement was a rare event: this module's own note records
+# "60 cycles of the §10.3 runaway produce 2 loop-side engagements". On the live
+# install it produced 48 IN 25 MINUTES of ordinary operation, because `max_w` is
+# 5000 W where the loop's tuning was derived at a 1500 W clamp (SAFETY-39) - so
+# the integrator reaches its bound constantly and the notification re-asserted
+# every 30 s, all day. An alarm that speaks that often about the normal case is
+# how an operator learns to ignore the one that matters, which is the exact
+# failure this module's docstring is written against.
+#
+# ⚠️ 150 s IS NOT A COMFORT CHOICE, IT IS THE REQUIREMENT'S OWN EDGE, WITH ONE
+# STEP OF MARGIN. test_clamp.py part 2 pins the cadence in WALL-CLOCK terms
+# rather than against this constant - a loop pinned on the rail must speak at
+# least MIN_PER_QUARTER = 5 times inside the 900 s quarter that bills the
+# capacity tariff. That caps this constant at 900/5 = 180 s. At 180 s the check
+# passes with exactly 5 of a required 5, so any later change to the firing logic
+# tips it red; 150 s gives 6. The floor is the thing that must not move.
+#
+# ⚠️ THIS IS A STOP-GAP AND SHOULD BE REVISITED. It reduces how often the alarm
+# repeats; it does not make the alarm correct. SAFETY-40 is the wording and the
+# i-clamped/clamped split, and SAFETY-39 is the tuning that would stop the loop
+# railing in the first place. Neither is done by this line.
