From c4e15ec4cd95003a2620e487684dab32751e3ca4 Mon Sep 17 00:00:00 2001 From: glenn schrooyen Date: Mon, 19 Oct 2026 14:14:08 +0200 Subject: [PATCH 01/11] SAFETY-119: no "not keeping up" when the loop takes the wire back When the peak guard or a maintenance charge hands the wire back, the loop's integrator is re-seeded from that owner's command and kicked by a meter that does not show it yet. It crossed its rail for a cycle or two and raised goodwe_integrator_bound while the battery gave what it was told. The loop's integrator bound is not counted until the plant's settle (SHORT_CYCLES, SHORT_SPAN_S) has passed since the hand-back. An over-rating always counts; a bound that lasts warns after the settle. No command changes and no text changes. test_safety119.py; DECISIONS entry.
