Apple: per-day wake times are edited on the alarm screen but only move the wind-down reminder #1864

Found while giving Android per-day wake times for its phone alarm (#1858).

What the setting does today

WindDownNudge.perDayWakeOverrides has exactly two readers:

• wakeMinutes(forWeekday:) → nudgeMinuteOfDay(forWeekday:) → the wind-down nudge fan-out;
• SmartAlarmView, which edits them.

Nothing else reads them. The alarm backup itself takes a single time plus a day set:

static func scheduleSmartAlarmBackupNotification(minutes: Int, weekdays: Set<Int>, …)

So a per-day override moves the evening reminder and leaves the wake on the default time.

Why that is worse than not offering it

The control lives in SmartAlarmView — the alarm screen — beside the wake time. Someone who sets "Tuesday 03:30" there has every reason to expect to be woken at 03:30 on Tuesday. They will be woken at the default time instead, with only the reminder shifting, and nothing on screen says so.

That is the same complaint that produced #1858 on Android, one platform over: a user asked for 04:45 on three days and 03:30 on two, could not express it, and reasonably concluded the feature was broken. Here it looks expressible and silently is not.

Options, since this is a scope decision rather than an obvious bug

1. Honour the overrides in the backup notification. It already fans out per-weekday ids (smartAlarmBackupIds, and it clears both shapes), so the structure is there — each weekday trigger would take that day's own time instead of the shared minutes. This is what Android now does.
2. Scope the control to what it actually affects — move it under the wind-down section, or label it as the reminder's schedule.
3. Leave it, if the backup notification is deliberately kept simple because iOS cannot ring a real alarm and the strap buzz is the real wake.

Worth a decision either way: the current state is the one option that misleads.

• Apple: the per-day wind-down nudge fires on the wrong day for an early wake #1863 — the per-day nudge fires on the wrong weekday for an early wake (a real bug in the same code, on both platforms; Android is fixed, Swift is not).
• Phone alarm has no per-day wake times, though the strap alarm on the same screen does #1858 / PR alarm: per-day wake times for the phone alarm (#1858) #1859 — the Android side, where per-day times now drive the alarm, the strap buzz, the guarantee card and the wind-down.

Also worth noting for whoever picks this up: Android now stores per-day overrides in TWO places — NoopPrefs.smartAlarmDayOverrides (strap, #554) and SmartAlarmStore.targetOverrides (phone, #1859) — while Apple has one. Same "dow:minute" encoding and validation on all three, so there is no format drift, but the question of whether one set should drive both alarms is open on both platforms.
