Struct MessageMetadata 

pub struct MessageMetadata {
    pub agent_visible: bool,
    pub user_visible: bool,
    pub compacted_at: Option<i64>,
    pub deferred_summary: Option<String>,
    pub focus_pinned: bool,
    pub focus_marker_id: Option<Uuid>,
    pub db_id: Option<i64>,
}

Per-message visibility flags controlling agent context and user display.

Fields

agent_visible: bool

user_visible: bool

compacted_at: Option<i64>

deferred_summary: Option<String>

Pre-computed tool pair summary, applied lazily when context pressure rises. Stored on the tool response message; cleared after application.

focus_pinned: bool

When true, this message is excluded from all compaction passes (soft pruning, hard summarization, sidequest eviction). Used for the Focus Knowledge block (#1850).

focus_marker_id: Option<Uuid>

Unique marker UUID set when start_focus begins a session. Used by complete_focus to locate the checkpoint without relying on a fragile raw index.

db_id: Option<i64>

SQLite row ID for this message. Populated when loading from DB or after persisting. Never serialized — always re-populated from the database on load.

Implementations

impl MessageMetadata

pub fn agent_only() -> Self

Message visible only to the agent (e.g. compaction summary).

pub fn user_only() -> Self

Message visible only to the user (e.g. compacted original).

pub fn focus_pinned() -> Self

Pinned Knowledge block — excluded from all compaction passes.
