worldValidation.check

Validates a world's own authored content, everything under source except the libraries, in one pass — the cargo-check equivalent for authored content. By default only the world is scanned (libraries are not yours to validate, and walking them is slow); pass scope = "libraries", "library:<name>" or "all" (world plus libraries) to widen it. It is read-only: it walks the source once, checks each asset folder against its type schema and each script against the textual checks, and reports the intentional placeholder checks flagged so they can be filtered out without hiding real problems. Filter options narrow the report by severity, category, code, source, or path; each pass returns the full report alongside a one-line summary.
