Two survivors of the review's mutations get a check each in
test_price_run_fixes.py (X1: a held export credited negative in the rolled
quarter; X4: the hold extended by a reading already past E). DECISIONS: the
slow-battery quarter (3456 W, same on e3e4ba6) and the replay of a
maintenance phase starting during the hold.

Conflicts (5 files, 9 hunks) resolved keeping both sides:
- p1.py: held_t (OPT-15) beside held_since (SAFETY-90).
- modetrade.py: chargers() takes targets (P4) and probe (OPT-15); decide()
clears the chargers, a probing refuser included, while a battery drains
(SAFETY-78); the docstring lists both rules.
- main.py: the roll goes into the SAFETY-90/91 projection chain
(`_peak_proj`); the SAFETY-95 drain-tail grid_w keeps the run-edge hold on
its other branch; the P4 forecast state and the hold state both stay.
- DOCS.md, DECISIONS: both lines kept, OPT-15 item refreshed.
Adaptations the merge needs:
- SAFETY-81 x F1: a rolled projection is not graded by the saturation alarm
until the quarter's first sample, as the old edge tick was not, so a
standing overload is still notified once per quarter.
- test_safety81, test_modes_p4: modes-on pins re-pinned (with a note), modes
off pinned to e3e4ba6; test_price_run_fixes: identity pins on e3e4ba6,
F1 reproduced at one inverter (SAFETY-91 already holds two), tests for the
drain and the day plan against the probe.

- A second unmeasured-headroom stop in a quarter latches the charge: a
headroom missing every other cycle flipped it 1799 times in 30 min.
- Unit test of the run-edge hold's end conditions and of a small step.
- Outside its probe a refuser does not make the others rest (M15 red).
- DECISIONS: one review line.

- DECISIONS: the Cheap hours change and why; the no-sun replay (the gain is
Leftover solar buying the evening's shortfall; the forecast added 0.14
EUR); the reconstruction bias stated plainly.
- DOCS: Cheap hours ignores the forecast; a reading from before midnight
is stale.
- The forecast line: "Solar still to come today: ..." (it is what is
left, and it stays within the 12-word limit).

F1: with battery modes on, the peak guard projects the quarter `now` is in
even before its first P1 sample (PeakTracker.project(roll=True)), and only
a measured stop latches the period. The edge tick no longer reads "no
seconds left", so a charge is not stopped and latched at a quarter edge.
F2: after a run edge the loop is held at E until the meter shows the step
(EDGE_HOLD_S, longer while the battery still moves). The replay gained a
lag model (dead time, reading age, P1 debounce, 1 s cycles) that shows
TEST-23's overshoot without the hold.
F3: a charge refuser's SAFETY-73 probe inside a cheap run is a charger
pinned at PROBE_W, the others rest, so the probe actually runs.
Modes off stays byte-identical to 5a4cdc2 (new late-P1 identity scenarios).

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.

Owner decision 2026-09-29. Selling is off until it can be judged on the price
the grid pays: packmode.SELLING_ENABLED = False makes read() answer
sell=False whatever the store holds, pack_sell is refused ("Selling is off
for now."), and the page has no selling switch; the sell code stays. Until
the P4 forecast, only Cheap hours only charges from the grid
(packmode.GRID_CHARGE_MODES); Leftover solar holds and gives in the
expensive runs. Help, Today and plan lines, DOCS and DECISIONS follow.
Replay, 16 days: Solar first + Leftover solar 19.44 EUR net (P2 19.33).

- A sale block on the plan no longer says "Worth up to" at the import
price: a sale earns the lower injection price.
- The selling switch help (EN/NL) and DOCS say the grid pays less than
power costs; DECISIONS records why P3 loses on the replay.
- test_modes_p3 part 11: modes on ignore the site trade switch (R13), a
battery in maintenance takes no part (R10), a headroom stop latches for
the period (R8). All three mutants survived before and are red now.

Cheap and expensive hours as runs of consecutive firm price slots
(priceruns.py); each battery's role per tick from its mode (modetrade.py):
grid charging for Leftover solar / Cheap hours only, never Solar first;
holding for the expensive runs; selling per battery (pack_sell) above the
spread and the floor. The site trade is sized inside the modes (loop bound)
and the peak guard's headroom; a run edge reseeds the loop. Cheap hours only
and selling are enabled on the Batteries screen and in the HA select
(appended). The site Why row no longer says "held back" when the peak limit
pushes power up (F2). Modes off: byte-identical to 7a00f12 on the trade path.

- A refusal past the log-once set or the 32 cap is counted in the log at
1, 10, 100 and so on, so a repeated attack stays visible.
- The logged topic is printable only (no forged log lines).
- mode_announcement(): the start-up store logic, now tested with a real
Store. A removed config topic stays stored, so a start with no broker
cannot forget it (rename case tested).
- A test ties each HA mode option to the page's English name.
- packmode.enabled() is tested for "true", 1 and "false".
- Retained-command text, DOCS and DECISIONS updated to match.

Each battery gets an MQTT-discovered Mode select and Use switch, only while
battery_modes_enabled is true. Commands go through handle_action(), the
/action path; refusals are logged once. Retained commands are never applied.
Turning modes off removes exactly the configs announced (kept in the store).
With modes off the announcement is byte-identical to ed739d4.

- arbiter: a mode now gives way only as far as a site limit above P_MODE
needs (_unit_modes at N>1, _site_mode at N=1). Before, the modes were
released only when the peak floor bound S, so a trade won above the floor
kept them and placed less than the floor (an Off battery at N=1 went to 0 W
under a 2000 W floor), and a capped grid charge released an Off battery.
While released, held batteries weigh 0 and carry only the shortfall.
- control: a side of the loop bound that reaches the rail is left to the
rail, so SAFETY-03's i_clamped still fires with every battery on.
- opt11_identity: add maintenance scenarios and a 6000-case arbiter digest
(peak floor, trades, maintenance, refusals); a5dddad digests pinned.
- tests: test_arbiter part 11, test_control (g), test_modes (0/1 refused,
loop bound counts live units only). DOCS and DECISIONS say the new rule.

A battery's mode is a soft unit limit (source `mode`, P_MODE 35) kept
apart from the hard limits in pre_resolve(). The allocator applies it
only while the site target is decided at or below 35 (new
Resolution.deciding_priority), so the peak floor releases it and a mode
`hi` never meets the site `lo`. At N=1 resolve() applies the same rule
to the site target after stage 2. A mode range without 0 W is dropped
as a software fault, so REFUSE_SIGN stays unreachable from a mode.
compute() gets the loop bound (sum over live units of hard limits with
modes applied), so the loop never asks for watts no battery may give
and the saturation freeze never parks on them. While charging, Leftover
solar weighs 0 so Solar first fills first. Store keys pack_use and
pack_mode per battery, set by two new /action values; Off stops and
skips maintenance with a log line. Minimal Batteries cards (EN/NL).
Off by default (battery_modes_enabled); off, commands are byte-identical
to a5dddad at N=1 and N=2 (test_modes.py part 1).
