Fields

session_id: u64

A facade-session namespace prevents the engine’s process-local u32 handles from colliding after restart.

handle: u32

revision: u32

kind: MobileChatMutationKind

conversation_address: Option<String>

sender_address: Option<String>

sender_hint: Option<Vec<u8>>

The sender’s 3-byte claimed hint, for a channel group message. The only sender identity a multicast frame is required to carry; present whether or not sender_address could be resolved.

direction: Option<MobileChatDirection>

message_type: Option<u8>

wire_id: Option<u8>

epoch: Option<u16>

client_token: Option<u32>

sender_handle: Option<String>

regarding_handle: Option<u32>

regarding_wire_id: Option<u8>

When a reply or emote references a message the engine holds no live handle for, these export the wire reference the same way the original_* fields do for edits: the target’s wire ID within regarding_direction’s stream, plus the hint identifying which member’s stream in a channel group.

regarding_direction: Option<MobileChatDirection>

regarding_sender_hint: Option<Vec<u8>>

background_color: Option<Vec<u8>>

text_color: Option<Vec<u8>>

original_handle: Option<u32>

original_wire_id: Option<u8>

When an edit/delete references a message the engine no longer holds a live handle for (composed before a restart), these export the wire reference so the platform can resolve it against persisted rows: the original’s wire ID within original_direction’s stream of the record’s conversation_address conversation.

original_direction: Option<MobileChatDirection>

original_sender_hint: Option<Vec<u8>>

The claimed hint of the original’s sender, for a channel group conversation. Inbound group streams are per-member, so matching a wire reference there needs the hint as well as the ID and direction.

body: Option<String>

complete: Option<bool>

present_fragments: Option<u16>

fragment_count: Option<u8>

finalized: Option<bool>

presence: MobileChatPresence

Ordered-slot presence for Insert records (spinner placeholder, real message, or loss marker). UpdateBody/Edit/Delete leave it at Present; the host does not reinterpret presence on those.

received_late: bool

The record fills a slot reserved earlier by a gap, so it arrived out of order and should render a “received late” caption.

notify: bool

The host should raise a user notification for this record (single-frame arrival, fragment completion, or notify deadline; never placeholders).

Whether a notification is actually shown remains the host’s decision — a muted conversation still produces records with this set, and still counts as unread.

rx: Option<MobileChatRxMetadataRecord>

Radio metadata for the frame that produced this record, when one did.
