//! Regression for #1584: a phantom-blocked section never reloads as the
//! turn's answer.
//!
//! The tool loop persists an iteration the phantom detector refused under
//! `<!-- phantom_blocked=1 -->` markers (#1172). The reload split knew only
//! the reasoning markers, so the section came apart into its opener line,
//! its reasoning, and its narration plus closing marker as the last text
//! segment, which is the final answer by position. A 21K-character wall the
//! self-heal had drained from the live view rendered in full on the next
//! reload, closing marker as its last line.
