F1: the evening rule has an age limit (KEPT_MAX_AGE_S).
F2: the evening bound is the next local midnight (_bounds), right on 25 h and 23 h days.
F5: test that old days are dropped from the stored hold.

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.

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.

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.

New list options pv_forecast_entities and pv_forecast_tomorrow_entities
(same shape as pv_entities); the single-entity keys are unchanged.
- Each member is read in its own unit (Wh/kWh/MWh) in one gather and the
day is summed. Hourly splits are merged when every member has one, else
the total goes on the bell.
- A member missing, unavailable, stale, non-energy or bad makes that
day's forecast unusable (no partial sum). A caution row names it by
position; the action log names the entity once per change.
- Single key and list both set for one day: refused at start.
- A one-member list behaves exactly like the single key (test_opt17.py);
the single-key path is byte-identical to e36565f over 24 scenarios.
- Supervisor shape measured: tools/supervisor_shape_probe.py section J.
DECISIONS/OPT-17-several-forecast-entities.md has the rules.

- Cheap hours only fills to the ceiling with or without a forecast, as the
design (section 1) says. Skipping the sun's share cost 0.31 EUR on real
2026 prices (29.72 against P3's 29.41) and saved nothing on the P3 set.
- A forecast reading from before local midnight is stale: until the
integration refreshes, "left today" is still yesterday's 0 and
"tomorrow" is really today.
- Forecast entity ids must be sensor.[a-z0-9_]+ (they go into the
/api/states/<id> path).
- House profile: a stored day that is not a date, or is after today, is
dropped instead of kept forever.
- Text: the forecast line says "for the rest of today"; the learning line
no longer promises "tomorrow" (a plan needs one full day).
- Tests for four surviving review mutants (hour sample floor, the dear run
after the cheap run, share by room, daytime use) and the fixes above.
- Replay tool: `--fc zero` (a forecast of no sun).

A Home Assistant solar forecast (Forecast.Solar, Solcast or Open-Meteo
shapes) and the add-on's own hourly house use decide, before each cheap
run, whether the sun will fill each battery before the expensive hours.
Leftover solar then buys from the grid only the shortfall; Cheap hours only
skips the part the sun covers; Solar first never grid-charges. No, stale or
failed forecast: P3 option A exactly (12 digests pinned from 5a4cdc2).
Replay (16 recorded days, forecast errors from Elia's day-ahead BE solar):
year-earlier prices P4 19.15 vs P2 19.33 / option A 19.44 / old trade 18.14;
real 2026 prices P4 29.19 vs 32.26 / 32.01 / 31.40 EUR net.
