Round the desired center to an integer first, then subtract w // 2, to match how Box.cx computes the connector position (x + w // 2). The old int(desired - w/2) truncated toward zero, biasing odd-width boxes 1 char left of their parent's visual center. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
int(desired - w/2)withround(desired) - w // 2in all 3 coordinate assignment phases. Rounds the desired center to an integer first, then offsets byw // 2— matching howBox.cx(x + w // 2) computes the connector position. The oldint()truncation biased odd-width boxes 1 char left, causing visible misalignment in linear chains with mixed even/odd box widths.book-writer-agentsample (6-node linear chain that exposed the layout bug) and regenerate all screenshots.Test plan
