SAFETY-125 round 2: the one-inverter maintenance charge is sized to the room too
Owner 2026-10-29: fix N=1 in this hotfix. _charge_headroom() no longer
returns early at one inverter, so the N=1 cheap-window maintenance charge
is held to charge_room_w() as at N=2; SAFETY-84's site-stop rule stays N>=2
only (at N=1 such a stop outranks the shaping anyway). The guard no longer
steps in and gives power at each quarter's end during that charge.

test_safety125.py: N=1 maintenance on 5 s and 10 s meters with late
readings, with and without a banked peak; the row in an N=2 maintenance
charge and in shadow mode; edge cases (blind past the hold, a start
mid-quarter, the summer-time change, the forecast in W, a 10 s meter, the
last second). test_safety84/87: three N=1 pins move. test_safety119: its
quarter-edge hand-back runs keep the old N=1 sizing as a fixture, plus a
check that with the new sizing nothing hands back. CHANGELOG, DECISIONS,
DOCS follow.

"""Runnable check for SAFETY-125. `python3 test_safety125.py`
A meter reading that is late near a quarter's end left seconds the
projection did not count (SAFETY-99), and `charge_headroom_w()` read them as
room: a grid charge went back to full power in the quarter's last seconds and
the billed quarter went over the aim, above a banked month peak or the cap.
And the peak guard's row said "under" while the period was over the limit at
the current rate. DECISIONS/SAFETY-125-grid-charge-under-the-month-peak.md.
Drives the REAL Controller (read_inputs + cycle, the tariff task on a
day/night profile, a P1 meter on a simulated clock) in the live shape: modes
on, inverter-a Cheap hours at 5000 W charging harder than asked (as it did
live), inverter-b Solar first, a house of 1 kW, cap 3500 W, margin 50 W.
1. `charge_room_w()` on its own.
2. A reading 30 s late at each quarter's end: every quarter at or under the
aim, with a month peak banked above the cap and with none, with the P1
projection and with a `peak_forecast_entity`; the charge is cut late in
the quarter and back in the next one.
3. The same for a price trade with modes off, and a maintenance charge at N=2.
4. A healthy meter: the quarters as before, and the row and the month-peak
line say what is true.
5. The words on their own.
6. One inverter: the maintenance charge is sized to the room too (owner
2026-10-29), on a 5 s and a 10 s meter, with and without a banked peak
and with late readings; the guard no longer steps in during it.
7. The row during an N=2 maintenance charge and in shadow mode.
8. Edge cases: a reading past its 30 s hold (blind), a start mid-quarter,
the summer-time change, the forecast entity in W, a 10 s meter, the
quarter's last second.
Mutations (MUTATION.md, purged copies) are listed in the pull request.
