Struct HandoffStatement 

pub struct HandoffStatement {

    pub type_: String,
    pub timestamp: String,
    pub from: String,
    pub to: String,
    pub artifacts: Vec<String>,
    pub approval_ids: Vec<String>,
    pub obligations: Vec<String>,
    pub delegatable: bool,
    pub task_ref: Option<String>,
    pub policy_ref: Option<String>,
    pub meta: Option<Value>,
    pub custody: Option<HandoffCustody>,
    pub close_loop: Option<CloseLoopEvidence>,
}

Records that work moved from one actor/domain to another.

This is the core of Treeship’s multi-agent trust story. A handoff artifact proves custody transfer and carries inherited approvals.

Fields

type_: String

timestamp: String

from: String

Source actor URI

to: String

Destination actor URI

artifacts: Vec<String>

IDs of artifacts being transferred

approval_ids: Vec<String>

Approval artifact IDs the receiving actor inherits

obligations: Vec<String>

Constraints the receiving actor must satisfy

delegatable: bool

task_ref: Option<String>

policy_ref: Option<String>

meta: Option<Value>

custody: Option<HandoffCustody>

How custody was established for this transfer.

Absent on every handoff minted before custody grading existed and on every handoff that recorded no verification. Absent means asserted, never live: the verifier grades a missing block exactly like an explicit assertion (see HandoffCustody::effective). Signed, so a holder cannot promote an asserted handoff to live on the wire.

close_loop: Option<CloseLoopEvidence>

Close-loop evidence the sender attached: a sealed local session whose receipt digest this handoff binds. It proves the sender ran the commands in that session; it does not bind the UI pixels or the task result to the presentation key. Optional by design – slice 4 of docs/specs/agent-to-agent-verification.md says a receiver may require it as policy, and v1 must not.
