Interface ExplainStructure

The Q16 tristate. "unknown" is a real value, not a missing one: a write-shaped command outside the small version-stable write table (/disk format-drive) must never report false.

statements.length, which counts BLOCK-BODY statements too — see ExplainStructure.statements. Not the number of top-level statements.

Every statement the analyzer read, in discovery order.

A do={…} body's statements are flattened in after their parent (which is what RouterOS IL does to them), so a body statement's span is CONTAINED by its parent's rather than following it, and spans may overlap. A consumer that wants only the top level filters on containment; one that wants "every command in this script" — the common case, and the reason to flatten — reads the list as it stands.
