Text only (DECISIONS, DOCS, CHANGELOG): a step load alarms on the same cycle
as before; a steadily rising load alarms a little later; with peak_margin_w 0
a period can end up to 10 W over the limit without this alarm, as for 'Load
too high' (SAFETY-81). Owner accepted 2026-10-31.
test_safety126.py part 2: after a real overrun ends, _peak_landing()'s latch
is reset and the night's later landings are quiet (review F3).
Co-Authored-By: Claude <noreply@anthropic.com>
During the night grid charge under the peak reserve the guard alarmed
(ERROR PEAK_GUARD_FLOOR_LIMITED, "Battery stopped limiting the peak") and the
Batteries "Why" said "The peak limit needs power" at quarter ends, while every
quarter landed on the aim. The charge lands the period 0-7 W over the aim and
excess_w()'s 900 / remaining turns that into tens of kW in the last second;
with nothing able to give, check_peak_floor_limited() alarmed on any
wanted > 0.
Each cycle the guard wants power, _peak_landing() asks misses_aim(): with the
batteries at 0 W, does the period end more than ALARM_MISS_W over the aim? If
not, the decision is within_aim: no reserve alarm, no red peak row, no "Why"
peak. The claim and the commands are unchanged. A real overrun under the
reserve alarms on the same cycle as before.

With battery modes off the forecast is still read and shown (Settings,
Simple, and the Forecast tab), but no plan uses it, so "used for tonight's
plan" was not true there (UX-53). "Kept for tonight" is true in every
shape. NL "vanavond" read wrong after midnight; "vannacht" covers the
whole night. DECISIONS' "modes off: nothing reads the sensors" corrected.

Hold.stand_in(): day0 <= now < day0 + 3 h. A tomorrow sensor is asked with
day0 = the next midnight, so the upper bound alone was true all day and a
figure stood in at any hour. test_opt27.py covers daytime tomorrow outages.

test_modes_p4.py: 'the forecast is lost mid-run' now loses it for good (a hold
that never covers); a second scenario is the same loss with the hold, which
keeps Leftover solar charging. test_opt27.py: a failing check no longer hides
the ones after it.

Forecast.Solar's sensors stop updating in the evening, so at night every such
site had no forecast: the night cheap run needed 1.5x the cycle cost and
Leftover solar planned nothing. One missed poll also dropped it at once.
solarfc.Hold keeps the last fresh reading of each sensor, for the day it is
for. A missing or stale sensor is covered by it for up to FRESH_S (a short
outage), and from the end of the bell (20:00) until local midnight + 3 h
however old. A tomorrow figure is tomorrow's until midnight and then today's;
a today figure is only today's. Stored in the controller's store
(solar_fc_hold), so an evening restart keeps it. The forecast line says
'Solar forecast read 17:05, used for tonight's plan.' (EN, NL).
test_tariff24_weather.py runs with a hold that never covers: it tests what the
plan does when the forecast IS lost.

UX-54's Forecast tab (release/1.0) re-plans tomorrow's cheap run as control
will, with the gap `required`. It still added the "no weather" x1.5 always,
while control (TARIFF-24, from master) drops it when a forecast is read. In
the UX-54 scenarios the tab asked 0.225 where control needs 0.15. It now asks
`arbitrage.weather_uncertainty(True, c.solar_fc)`, so the two agree again, as
they did on release/1.0 alone. Display only; no control change. The tab's
blocks in every UX-54 scenario, every 2 h, are identical to release/1.0.
test_ux54.py pins it (the old line fails it). The TARIFF-24 DECISIONS note
names the tab as the fourth place that reads the rule.

- TARIFF-24 DECISIONS: the hold keeps a Cheap hours charge; a Leftover solar
battery still stops without a forecast (it has no planned level, still true
after OPT-28: `dayplan.plan()` returns None and `charge_to()` gives None).
Adds "a run that has started runs to its end" for a give run begun in a hold.

Part 6 of test_tariff24_weather.py, the review's probes R4 and R5:
- R4: a forecast lost while only the day's give run is under way holds to
that run's end (22:00) and no further; the night's cheap run then needs the
wider gap. Pins the `solar_fc is None` return in `_wx_track()`: without it
the hold chains into the cheap run and B charges (mutant M2, now red).
- R5: a give run that starts during a hold runs to its end (`keep_started()`),
with no grid charge after the hold. Behaviour unchanged; a give run not kept
goes red.

With master merged in (TARIFF-24), a forecast replaces the 1.5x widening, so
the shipped cost 0.10 is now the whole gap with a forecast. test_ux54.py's
modes-on scenarios were written for 0.15 and 21 of its checks failed on
release/1.0 + master (they pass on release/1.0 alone). They now set the cost
to 0.15 where they have a forecast: the same gate as before. Scenarios with no
forecast (nofc, stale) and modes off keep 0.10, widened as before.

without a text conflict. config.yaml's version becomes 0.19.2, the newest
CHANGELOG section: test_version_gate.py (PKG-14, 11b) requires the two to be

N kWh, comes from another battery or the grid." (NL likewise). DOCS,

OPT-23: a state-only forecast is read from now for every span
(Forecast.between since=), so the plan's per-hour sun adds up to the day's
figure, today and tomorrow. Hourly splits are unchanged. The Forecast tab
reads spans the same way.
OPT-28: a Leftover solar battery buys, from the floor, the sum over the
expensive hours of max(0, house - trust x sun), / EFF. Several Leftover
solar batteries hold it together by capacity, the ceiling passes the rest
on, and what none can hold is said (Plan.uncovered_kwh). Home's grid block,
the Batteries line and the mode help (EN + NL) say the level, what it
covers, and that Leftover solar buys only what the sun will not give.

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,

- The over-the-limit rows ran over STYLE's 15 words (EN 16/19, NL 16/21)
and two Dutch Home sentences over 12 words; they were not in the samples,

The rows and the line are added to the samples. The under row is unchanged.
- CHANGELOG known issues and the DECISIONS note: at N=1 the maintenance
charge is not sized to the room, so SAFETY-99 still applies to it.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A meter reading late near a quarter's end left seconds the projection did
not count (SAFETY-99), and charge_headroom_w() read them as room: the cheap
run (and price trading, and the N=2 maintenance charge) went back to full
power in the quarter's last seconds and the quarter could land over a banked
month peak or the cap. peakguard.charge_room_w() counts those seconds at the
held reading for the charge only; the guard's floor is unchanged.
The guard row said "idle, heading for 5 814 W, under this month's 5 413 W
peak". Over the limit at the current rate the row and the month-peak line
now say so, and that the grid charge is cut back.
Version 0.19.2, CHANGELOG, DECISIONS. test_safety125.py new; the lag pins
in test_price_run_fixes.py and test_opt20.py and the AST pin in
test_arbitrage.py follow the change (see the pull request).

Losing the solar forecast mid-run used to widen the gap at once and stop a
grid charge (and a sensor that went unavailable for a minute stopped and
restarted it). A run under way when the forecast is lost now keeps the gap it
was planned with until it ends (Controller.weather_held(), recorded by
_wx_track() each cycle a forecast is read); the wider gap applies from the next
run. The plan key holds the hold state so the plan rebuilds when it ends. Home's
mirror (homeview.trade_verdict) asks the same weather_held(now).
Tests: test_tariff24_weather.py part 4 (going: the charge continues to the run's
end, the next run is not_worth; flap of one and two reads: no stop, no restart;
Home agrees) and a test_modes_p4.py scenario that runs a forecast day at a gap
between 1x and 1.5x the cycle cost. DECISIONS wording follows.
Co-Authored-By: Claude <noreply@anthropic.com>
With a forecast read the gap needed is the cycle cost (0.20), not 1.5 x (0.30),
so a midday 0.21 gap now plans a grid top-up that four scenarios (sunny, Cheap
hours partly, forecast too high, refusal) are not about. They ask for cost 0.30
with the forecast; the no-forecast leg keeps 0.20 (= 0.30 widened).

With battery modes on, the price gap a mode needs was always widened x1.5 by
Uncertainty.NO_WEATHER, even with a solar forecast read, so a 0.08 day/night
gap never traded at the shipped cycle cost. The doubt is now added only when
no usable forecast is read (solar_fc is None, the day plan's own test), in the
run plan (_price_runs), the charge gate (_mode_roles) and Home's mirror
(homeview.trade_verdict). The rule is one helper, arbitrage.weather_uncertainty();
the modes-off trade path (main.py cycle) keeps its literal NO_WEATHER.
DOCS "Battery modes" sentence, CHANGELOG 0.19.1 line and the DECISIONS note
follow. Tests: test_tariff24_weather.py.

With battery modes on, a day/night or fixed static_profile, no price feed and
arbitrage off, tariff_refresh_wanted() was false: no tariff task, no
tariff_plan, mode_runs None, so Leftover solar / Cheap hours never charged from
the grid and the Batteries screen said "No prices". packmode.enabled(opts) is
now a third term of the gate. With price_provider off the task is pure
arithmetic on static_profile, so no HTTPS call is added.
Also: version 0.19.1, CHANGELOG entry, DECISIONS note, test_tariff24.py, and a
shorter tariff_refresh_wanted() docstring (history stays in DECISIONS).

daycurve._floor_cut() set a cut from a battery already at the floor (its
cap 0 is below its rating), so a give run with one battery empty and the
other held to its rating was cut until MAX_FLOOR_CUTS ran out: 2,800 cuts
and 460 ms a build, and give blocks back at the hour edge after that.
The shortfall in a step is now shared as control shares it (by what each
battery holds above the floor, packshare.weights(), each at most its
rating, the rest passed on), in the step and in the cut. A battery giving
v kW that holds h kWh is empty at h / v; one at the floor holds nothing and
never sets a cut. The cut lands where the step then comes out exact, so it
is placed once. curve(stats=) reports the floor cuts and whether the bound
stopped one.
test_ux54.py: _floor_cut() checked to the second against floor times worked
out by hand (one battery, a group with one held to its rating, the second
group, the split by what they hold), a battery at the floor sets no cut,
the bound is reported; own_walk() with the reviewer's two cases (30/80 %,
guard, 7 kW house; 2 x 3 kW, 3.5 kW house) and, per build, the floor cuts,
the level points and the time.

daycurve.curve() puts a point where a giving battery reaches the floor
inside a step (_floor_cut(), as it already does for a grid charge reaching
its level), so _stops() ends a give block in the quarter control stops. A
walk where control moves the packs with its own model (not the curve's
levels) matches the tab quarter by quarter in 11 cases; 25/45 % with the
peak guard: control 17:00-20:15, block 17:00-20:06.
SolarToday keys an hour by its start taken back from the UTC instant, so
the two 02:00 hours of the autumn change stay apart. test_ux54_dst.py builds
the tab (forecast_payload()) at every quarter of 27-29 March and
30 October-1 November 2027, modes on and off, in the no-tzdata zone and,
where the host has tzdata, ZoneInfo, every call under a time limit raised
as a BaseException that forecast_payload() cannot swallow.

dayplan._hour_slices() added an hour to the local wall clock and read it
back. Without tzdata (tariff._EUTimezone) 02:00 on the spring change reads
as 00:00 UTC again, so the loop never advanced and the list grew until the
process died. Each step now adds the time left in the local hour to the UTC
instant. Ordinary days give the old slices; the spring day gives 23 slices
and the autumn day 25. No option, no text change.
test_safety123.py: every quarter of 27-29 March and 30 Oct-1 Nov 2027 (and

Modes off has no curve (no forecast is read, no house profile kept), so
dayview._levels() never ran there and tomorrow's legs were drawn from the
bound. homeview.trade_runs(ahead=f) now reads each leg at f(name, kind,
start), as mode_runs() does: no give while the emptiest battery is at the
floor, each share sized from that level. dayview._counted() gives a give
the level by Home's own count (the level now, plus what the blocks before
it put in, less what they take out); a charge is read from the floor,
because a full battery covers the house before the cheap hour.
The battery line says a give is planned when one is and the battery has
no give block, also with modes off.
test_ux54.py: the modes-on walk no longer relabels a GIVE role at the
floor; it asks control's own discharge envelope (packshare.envelope())
with each pack's cut-out at the floor. The peak-guard 20 % case asserts
the curve is at the floor at the 17:00 give start. A modes-off walk on a
cloudy day (arbitrage.decide() with the cycle's inputs, the packs moved by
what control does and by the house), cases A-D: control charges and gives
in exactly the quarters the tab has a block. trade_runs(ahead=f) unit
check. _stops() ends a give block where the level the tab shows is at the
floor (LEVEL_DP).

- Tomorrow's grid block is drawn to where control stops charging. A cheap run
is sized for all batteries together; a slower one is still below
`charge_to()` when it ends and control plans the next cheap slots. The tab
asks `modetrade.energy()` and `priceruns.plan()` with the packs at the
curve's level and extends the run, so the curve charges as long.
- Each battery's block ends where it is at its own level (grid) or at the
floor (give). The curve puts a point where a battery reaches its charge
level inside a step.
- `homeview.mode_runs(ahead=f, rp=...)` reads each block at the level the
curve has when it starts, with Home's own filter and MIN_KWH: no give block
at the floor, no grid block at the planned level. Home never passes either.
- `no_tomorrow` names the hour from `solarfc.BELL_FROM_H`, where the curve
stops.
- test_ux54.py part 7 compares control (`_mode_roles()` every 15 minutes) with
the tab with no tolerance, and adds the cloudy / floor case.

F1: tomorrow's blocks no longer depend on the battery's level now. Home sizes
a block from the level now (`room()`, `plan_need()` in mode_runs, the leg
sizing in trade_runs) and draws none when there is no room or energy. For a
day that has not started the builders take `ahead=True` (Home never passes
it): a charge is read from the floor, a give from the ceiling. A grid block is
then kept only where `modetrade.chargers()` would charge at the curve's level
when the run starts. The UX-53 gate is unchanged. Today still equals Home; a
give run in the plan with no block (empty battery) has its own sentence
instead of "No charge or give blocks planned".
F2: test_ux54.py part 7 walks the real `_mode_roles()` every 15 minutes
through tomorrow and compares the roles with the tab's blocks (modes on, the
peak gate, part-full batteries), and the control cycle's verdict at 07:00
(modes off).
F3: the curve counts spare solar as trust x max(0, sun - house), stored at
EFF, as `dayplan.plan()` does (10 kWh sun, 2 kWh house, 70 %: 5.32 kWh).
Strings: cycle, no_tomorrow, ahead, no_level, measured; new give_later.

A new tab beside Home and Batteries for today and tomorrow: the solar
forecast, the solar measured so far, the house's expected use and each
battery's expected level, with the plan's own charge and give blocks under it.
- Blocks are Home's: today's are the plan's `runs`, tomorrow's come from the
same builders (`homeview.runs_for()`), in the plan lines' words.
- The sun is what solarfc reads; a daily total is spread over the bell and the
tab says so. The house is HouseProfile.estimator(), as the plan reads it.
- The level is new: `daycurve.curve()` gives each battery the role
`modetrade.decide()` gives it and moves it hour by hour inside the plan's
floor and ceiling. It is an estimate and counts on `solar_trust_pct`.
- Built on request (`GET forecast`), no Home Assistant call. Measured solar is
kept per hour in memory from the reading control already takes.
- A part not known yet is a note: modes off, no forecast, learning, no
forecast for tomorrow, a monthly cycle, no level, stopped, shadow.
No decision, command, timing or option key changes. Found, not changed:
`dayplan.plan()` over-counts a state-only forecast (DECISIONS/UX-54).
