- rootUnion: schema values are compared through a key-sorted rendering, so two
discriminator constants written as {a,b} and {b,a} are recognized as the same
value rather than as mutually exclusive alternatives.
- selectBranchIndex: after the const and required passes, a name only ONE
alternative declares identifies that alternative; a name several declare is
ambiguous and says nothing.
- additionalProperties counts as restrictive only when its schema states an
assertion — an annotation-only `{ title: ... }` is the equivalent of
`true`, like `{}`.
- Drop the unjustified double casts from the ToolTestModal fixtures; the
schemas are assignable to Partial<Tool> as written.
