An explicitly empty section header incorrectly inherits content · case 04
An explicitly empty section header incorrectly inherits content in the controlled document model.
Case contract
Each section header is a string or None; None links to the previous resolved header, initially default, while empty string explicitly clears it.
Why this case matters
Structured editing must preserve document semantics independently of visual rendering.
One recorded failure
