Struct AttachmentIntent 

pub struct AttachmentIntent {
    pub attachment_id: AttachmentId,
    pub session_id: String,
    pub canonical_uri: String,
    pub intent_at_epoch_ms: u64,
    pub owner_kind: Option<AttachmentOwnerKind>,
    pub owner_id: Option<String>,
}

A pending attachment write recorded before the bytes hit the AttachmentStore backend.

The runtime calls AttachmentManifest::record_intent from the SessionAttachmentStore wrapper before each put, so the manifest is a durable record that “some bytes are about to land at this URI.” When the turn that references the attachment commits successfully via SessionCommitStore::commit_runtime_state, the same transaction stamps committed_at_epoch_ms. Periodic GC sweeps manifest rows whose intent has aged past a host-chosen threshold without ever being committed and deletes the corresponding bytes — that’s how we reconcile orphaned files left behind by crashes between put and the next turn commit.

Fields

attachment_id: AttachmentId

session_id: String

canonical_uri: String

Canonical, stable identity for the session-owned physical object. Backends may map this identity onto their own path/key representation.

intent_at_epoch_ms: u64

owner_kind: Option<AttachmentOwnerKind>

Stable durable owner that can eventually commit or release this intent. Both owner fields are absent for direct host puts made outside a runtime execution scope; those rows retain fallback timer semantics.

owner_id: Option<String>
