# SAFETY-119 - no "not keeping up" when the loop takes the wire back

**Status: for review.** Tests: `test_safety119.py`.

**Cause.** When another owner (the peak guard, a maintenance charge) has set
the wire and the loop wins again, `cycle()` re-seeds the integrator from that
owner's command, and `compute()` adds `gain * error` from a meter that does
not show that command yet. On the TEST-23 rig (SAFETY-118 I-2) the guard
stepped from -2000 W to +429 W with 5 s left. A cycle later the loop's ask
crossed the +2500 W rail and beat the guard's floor, so SAFETY-85 rule 1
counted it as the loop's own bound and raised `goodwe_integrator_bound`. The
battery gave what it was told, and the cap held.

**Decision.** After a hand-back, the loop's integrator bound is not counted
until the plant's settle has passed (`SHORT_CYCLES` cycles and
`SHORT_SPAN_S`, the window SAFETY-85 grades a battery on). After that it
counts as before. An over-rating (`clamped`, a bug) always counts. No command
changes, and no text was added or changed.

**Kept.** The loop in charge at its rail warns on the same cycle as before.
A loop still at its rail after a hand-back warns once the window has passed:
22 s at a 2 s meter, 55 s at 5 s. Delay, not loss. The start and a restart
after a stop are not hand-backs.

**Re-pinned.** test_safety84 (all six) and test_safety87 (`n1_crossing`,
`n1_above`, `n1_charge_low`): only OUTPUT_CLAMP log rows differ; commands and
claims are the same (`test_safety119.py` part 5).

**Open.** If another owner and the loop swapped the wire every few cycles,
each swap restarts the window and the loop's bound would not be counted.
A loop at its rail beats a floor or ceiling on its own side, so it keeps the
wire; a swap needs a claim that keeps outranking it.

**Not changed.** The kick itself is control behaviour: for a few seconds at
a quarter's edge the loop asks up to its rail. In `test_safety119.py` part 1
that is more discharge than the guard asked at a quarter's end, and a few
seconds of up to 500 W more charge at the next quarter's start.
