-# UX-53 - Home draws a grid charge only where the add-on will take it
-
-**Status: DONE 2026-10-26 (owner go 2026-10-25, from the PRICE-02 rig test F-1 and F-2).**
-
-## Decision
-
-Home asks the add-on's own gate, and does not decide for itself.
-
-- **Modes on.** `Controller._mode_roles()` files the gate it just asked
-  (`TariffPlan.arbitrage()` with the measured peak guard) as `mode_gate`: None
-  when it allowed a charge, else its reason (`peak`, `not_worth`,
-  `not_covered`). While it is set, `homeview.mode_runs()` draws no grid charge
-  and `price_windows()` marks no cheap quarter. Control never reads it. A
-  refusal that is not the gate (no measured headroom, a battery cycling) is
-  not filed, so those pages are as before.
-- **Modes off.** A charge the verdict puts after its last dear period is
-  refused when its time comes: the quarters left are all equal. `leg_taken()`
-  asks `trade_verdict()` (the control cycle's own call) at the leg's start and
-  keeps the leg only if the gate allows it there. A leg in progress is the
-  verdict's own answer now. The sale, "Tomorrow:" lines and chart marks use
-  the same answer.
-- **Words.** "Lowest/Highest published price" becomes "Lowest/Highest price
-  left" (the verdict reads only the periods not yet over). The flat-tariff
-  refusal calls a site "a fully fixed product" only when its product is fixed.
-
-## What does not change
-
-No control decision, command or option. Day/night and hourly sites with a
-second day of prices keep both legs at every half hour of a day
-(`test_ux53.py` part 4), except where every price left is equal: with an
-all-night weekend, Friday's 22:00 charge is no longer drawn, as the add-on
-does not take it. Price-off sites draw nothing, as before.
-
-## Limits
-
-The leg's gate is asked on today's plan, as the control cycle will find it at
-that time. A plan that gets new prices in between is drawn again at the next
-refresh. While the peak guard holds, a modes-on page shows no grid charge at
-all, also not the rest of a run the add-on charges in once the guard clears,
-as the modes-off page already did.

-   the gate open the charge is drawn as before. The real `_mode_roles()` runs
-   at each instant, so the page is graded against the decision it makes.
-2. Modes off (F-2): the verdict's charge comes after its last dear period.
-   Home asks the same gate at the charge's own start (`homeview.leg_taken()`):
-   a flat remainder is refused there, so no charge is drawn and no quarter is
-   marked cheap. A charge the gate allows at its start is drawn as before, and
-   so is the sale.
