…tent/slash_solver/expire_intent - Add boundary tests (now == deadline) for all four lifecycle functions to document and pin the exact behavior at the boundary second - add/fill use >= (deadline is exclusive for the action window) - slash/expire use < (deadline is inclusive — action is valid at the deadline second itself, not strictly after) - Add rustdoc boundary-semantics comments next to each comparison site Closes stellar-vortex-protocol#42
