Enum LearningSource

    Usync,
    PeerPnMessage,
    PeerLidMessage,
    RecipientLatestLid,
    MigrationSyncLatest,

    Pairing,

    Other,
}

The source from which a LID-PN mapping was learned.

The source is load-bearing, not just provenance: it selects the write policy applied when the pair reaches the cache — see lid_pn_write_policy in the whatsapp-rust client, which mirrors WhatsApp Web’s createLidPnMappings switch (learningSource). Directed sources overwrite on any change; observational bulk sources (Other and friends, WA Web "other") only seed new LIDs and re-resolve conflicts via a live query; known-stale sources are stamped created_at = 0 so they never outrank a fresher mapping for the same phone (the PN→LID resolution direction; the LID→PN reverse map always takes the latest write).

Variants

Usync

Mapping learned from usync (device sync) query response

PeerPnMessage

Mapping learned from incoming message with sender_lid attribute (sender is PN)

PeerLidMessage

Mapping learned from incoming message with sender_pn attribute (sender is LID)

RecipientLatestLid

Mapping learned when looking up recipient’s latest LID

MigrationSyncLatest

Mapping learned from latest history sync migration

MigrationSyncOld

Mapping learned from old history sync records

BlocklistActive

Mapping learned from active blocklist entry

BlocklistInactive

Mapping learned from inactive blocklist entry

Pairing

Mapping learned from device pairing (own JID <-> LID)

DeviceNotification

Mapping learned from device notification (when lid attribute present)

Other

Mapping learned from other/unknown source
