Struct NotificationPreferences 

pub struct NotificationPreferences {
    pub version: Vec<u8>,
    pub rules: Vec<NotificationRule>,
    pub digest_interval: Option<Duration>,
    pub timezone: String,
    pub digest_overrides: Vec<NotificationDigestOverride>,
    pub effective_delivery: Vec<EffectiveDelivery>,
    pub next_digest_at: Option<Timestamp>,
}

Stored settings and weft-owned read projections are distinct. The inbox is the record and never waits for an email digest. ObserveNotifications with include_preferences returns all these fields in the same preferences payload.

Fields

version: Vec<u8>

rules: Vec<NotificationRule>

digest_interval: Option<Duration>

Email-only account cadence: zero disables scheduled digest email; supported nonzero intervals are one hour, one day and one week. Supplied durations require zero nanos and seconds in {0, 3600, 86400, 604800}, otherwise INVALID_ARGUMENT / FIELD_INVALID. Absence uses weft’s daily default. This does not delay inbox items or push.

timezone: String

IANA timezone anchoring email digest windows; empty uses weft’s default.

digest_overrides: Vec<NotificationDigestOverride>

One override per Spool. Removing an override restores the account default. Cadence can be overridden without overriding any routing rules.

effective_delivery: Vec<EffectiveDelivery>

Read-only resolved cells, not stored rules. Complete account matrix plus sparse cells whose result differs in configured Spool scopes. Unique by (kind, spool, actor_origin, channel), at most 4096 cells and 1 MiB encoded for the complete preferences message. No silent truncation: a larger read fails with RESOURCE_EXHAUSTED / QUOTA_EXCEEDED. Omitted Spool cells inherit the account cell. Only currently authorized Spool scopes may be disclosed. Weft owns defaults and precedence; clients must not infer defaults from missing stored rules. RULE identifies a matching stored rule, DEFAULT a weft default. A locked email cell is always IMMEDIATE.

next_digest_at: Option<Timestamp>

Read-only next account email digest window, absent when its effective interval is off. A schedule projection, not a promise of queued email.
