pub fn release(node: &str, assignee: &str) -> Result<String>Expand description
Hand a session node back before it is terminal: ready again, assignee cleared, generation moved. A node the claim graph no longer holds (a lease reclaim freed it, a completion ended it, the graph never had it) still hands back a tracker heading left STARTED under this holder or under nobody.
§Errors
The claim graph’s refusal: held by somebody else, or not held and the tracker has nothing of this holder’s to hand back.
