Struct NodeCancelOutcome 

pub struct NodeCancelOutcome {
    pub node_id: NodeId,
    pub cancelled: bool,
    pub already_terminal: bool,
    pub rolled_up: Option<Status>,
}

Outcome of a cancel_node transaction — a single-node, branch-preserving cancel for one live fan-out child.

Per-node cancel deliberately leaves the run non-terminal while any sibling is still live (design §2.5 — a stuck child is unblocked without killing the batch). But when this cancel settles the last live node, the run is rolled up in the same locked transaction (rolled_up) rather than deferred to the supervisor — so a run whose supervisor has died is never stranded non-terminal (llm-review C1).

Fields

node_id: NodeId

The node this call targeted (fully resolved).

cancelled: bool

True when this call ensured the node carries a terminal cancel in the source-of-truth log — either by synthesizing and durably appending a fresh cancel node.report, or by re-folding a prior interrupted cancel’s already-logged event (crash convergence, no duplicate append). False when the node was already terminal on entry (see already_terminal).

already_terminal: bool

True when the node was already terminal on entry (merged, failed, or a prior cancel already folded) — a clean idempotent no-op, never a fresh cancel. Mutually exclusive with cancelled.

rolled_up: Option<Status>

Some(status) when this cancel settled the last live node and therefore rolled the whole run up to a terminal status under the same lock (Cancelled when no sibling failed, Failed when one did). None when siblings remain live (the run stays live) or the run was already terminal on entry. Lets the CLI tell the operator whether the run itself is now settled rather than implying a rollup that might never come.
