Static text assertions in test/unit/scripts/public-api-advanced-guide-shape.test.ts

Effort: S

This file reads advanced guide prose and asserts substrate, replay,
trust, and coordinate export wording.

Replace it with executable guide examples that run against a fixture
graph and verify the shown result shapes. Documentation should reuse
those examples instead of being line-matched.
