too many notification event names

Error message

too many notification event names

What it means

This error is thrown by NotificationConfigUpdate::parse when the parsed EventSoundEvents TOML array contains more than 6 entries. After re-parsing the raw text as a TOML table, the code enforces a hard cap of 6 event names per notification setting. The limit keeps the notification config bounded and canonical.

Solutions

1. Reduce the list to at most 6 event names, keeping the most important ones.
2. Deduplicate the list first — repeated names count toward the limit.
3. Use wildcards/global sound-enabled settings (EventSoundEnabled) instead of enumerating many events individually.
4. Use only recognized event names (those accepted by NotificationEvent::parse); unknown names fail the next step anyway.

Example fix

// before
event_sound_events = ["e1","e2","e3","e4","e5","e6","e7"]
// after
event_sound_events = ["e1","e2","e3"]

fn valid_event_list(names: &[&str]) -> bool { names.len() <= 6 }

When it happens

Trigger: Calling NotificationConfigUpdate::parse with K::EventSoundEvents where the TOML array parses successfully but has 7 or more string elements.

Common situations: A user subscribes sound notifications to every event the system offers; an editor or script appends event names cumulatively without deduplication, eventually exceeding the cap.
