/**
 * argumentLeaves — what "a string argument" MEANS, in one place.
 *
 * Pattern: a pure generator leaf, zero imports.
 * Role:    two checks now read the arguments of a tool call — the choice
 *          seam's `unsupported-argument` (did the value come from what the run
 *          served?) and the write seam's `empty-lookup` (the run produced this
 *          value, and the lookup for it came back empty). They must agree,
 *          exactly, about which leaves of an arguments object are candidates
 *          and what their dot-paths are: the second check's whole job is to
 *          notice something about a value the first one already excused, and
 *          two spellings of "every string leaf" would eventually disagree
 *          about which value that was.
 *
 * The dot-path is the finding's `predicate` on both sides (`machine`,
 * `filter.hosts.0`), so it is identity-bearing and not a convenience.
