+## v0.309.0 — the simpler notification page: three group switches (R-388 slice 1) (2026-10-12)
+
+**MinAgent: 0.131.0** (unchanged — no agent call changed). **No wire change, no hub change:** the page still saves the
+same `enabled_events` list. Design `08-alarm-ladder.md` §8.1, `09` §3 decision 200; operator answers 2026-10-12 evening
+(Q1 „as picked": group 3 on for households; Q2 „as picked": the cooldown field under „Részletek").
+
+- **R-388 slice 1 — three switches instead of eighteen.** The notification page shows „A gépem és a meghajtóim" /
+  "My machine and drives", „Az alkalmazásaim" / "My apps" and „Amit mi intézünk" / "What we handle", each one switch
+  with one sentence of what it sends. Membership is §8.1's table (`settings.NotificationGroups`; all 18 switches of
+  v0.308.0 are in it, each in exactly one group). Switching a group on or off writes or clears all its detectors.
+  A group whose saved detectors are partly on shows „egyedi" / "custom" and saving the page without touching it
+  stores the list **unchanged** — no household's saved choice changes. The 18 per-detector switches (now ordered by
+  group) and the cooldown field sit under a „Részletek" / "Details" fold (`<details>`, no script). A form without
+  the new group fields (an old page left open) is handled exactly as before.
+- **Not changed, for the lead to decide:** `settings.DefaultEnabledEvents` fills **no** group completely —
+  machine misses `storage_reconnected`; apps misses `app_start_failed` (OFF by the R-329 ruling, 2026-08-23);
+  „what we handle" misses `backup_integrity_failed`, `crossdrive_failed`, `health_recovered`. So a fresh box (and
+  every household on today's default) sees all three groups as „egyedi". Pinned by `TestR388_DefaultListAsGroups`.
+- Tests (`internal/web/r388_notif_groups_test.go`, the real render + the real save over a temp-file `Settings`,
+  posting back exactly what the rendered form carries): `TestR388_EveryPageSwitchIsInExactlyOneGroup`,
+  `TestR388_EachGroupRoundTrips` (RED without the switch-off branch: „group machine switched off still stores
+  [...] — the ticked details overrode the group switch"; RED without the switch-on branch: „group machine switched
+  on stored [], want exactly [...]"), `TestR388_CustomGroupSavedBackUnchanged` (RED with an unticked group always
+  clearing: „an untouched save CHANGED the stored list"), `TestR388_CustomGroupSwitchedOnTakesAll`,
+  `TestR388_FullListRendersThreeGroupsOn`, `TestR388_DefaultListAsGroups`, `TestR388_DetailsFoldSavesAnIndividualSwitch`.
+- **Parity fixtures:** `settings_notifications_hub` and `settings_notifications_clear_confirm` re-captured for this
+  template change (the switch list regrouped under the fold, the three group switches added; the two old section
+  labels „Hibák és figyelmeztetések:" / „Tájékoztató:" removed with their keys); a new case
+  `settings_notifications_groups_custom` (every group „egyedi") captured when born. No other fixture moved.

Before R-182 one event was both, and did neither: nine arrived, two were mailed, seven vanished before `LogNotification`. **Lifetime is `admissionSet`'s exactly** — absent collector means "no run in flight", never a stale answer. **A refusal is noted ONCE, inside `admitApp` where the verdict is taken**, not at the three legs that consult it: R-181's one-verdict-covers-all-three contract makes per-leg noting produce "2 of 1 apps failed". **Deliberate skips (disconnected / decommissioned) must NEVER be noted** — they have their own alert and a nightly digest about an unplugged drive is an ignored digest. **A clean run emits NOTHING**; silence is safe only because the hub's deadline check (`monitor/deadline.go:396,417`) raises a missed backup from report freshness independently — if that is ever weakened this design loses its footing. **`run_id` is unique per real run** (so the hub's 1-h cooldown cannot collapse a manual run into the nightly one) and **deliberately EMPTY on the periodic refresh sweep**, which must stay under that cooldown or a polled status page becomes a mail flood |

+#### The page: three group switches (v0.309.0, R-388 slice 1, `08` §8.1, `09` §3 decision 200)
+
+The notification page shows three switches instead of one per detector — „A gépem és a meghajtóim" / "My
+machine and drives", „Az alkalmazásaim" / "My apps", „Amit mi intézünk" / "What we handle" — each with one
+sentence of what it sends. The membership table is `settings.NotificationGroups` (every detector on the page
+is in exactly one group, pinned by `TestR388_EveryPageSwitchIsInExactlyOneGroup`). A group is a VIEW over the
+same `enabled_events` list: no wire change, no hub change. A group with some detectors on and some off shows
+as „egyedi" / "custom". The per-detector switches and the cooldown field sit under a „Részletek" / "Details"
+fold (`<details>`, no script). The save rule (`Server.applyNotificationGroupSwitches`): a group switch the
+household MOVED wins (sets or clears all its detectors); a group switch left where it was rendered leaves the
+per-detector switches authoritative — so a custom group saved untouched writes the list back byte-for-byte
+(`TestR388_CustomGroupSavedBackUnchanged`). A POST without the `group_<key>_shown` fields (an old page) is
+handled exactly as before. Note: today's default list fills NO group completely (each misses a member), so a
+fresh box shows all three as „egyedi" (`TestR388_DefaultListAsGroups` pins this until the default is decided).
