 * exist on disk as a real `.java` or `.kt` file (see this module's doc
 * comment for why existence, not a bare textual join, is required).
 *
 * No-op (returns `specifier` unchanged) when:
 * - `sourceRoots` is empty or `workspaceRoot` is absent (nothing to resolve
 *   against),
 * - `specifier` isn't a bare/dotted identifier path (already a slash path,
 *   a relative specifier, or a wildcard-suffixed package -- none of these
 *   are FILE-shaped, so an existence check against a single file candidate
 *   doesn't apply),
 * - no candidate resolves to a real file (an external library, a
 *   non-standard layout, or a package-only wildcard import that names a
 *   directory rather than a file all fall through here, exactly as
 *   unresolved today).
 *
 * @param specifier - The raw (pre-`normalizePath`) Java/Kotlin import specifier.
 * @param sourceRoots - Candidate source-set directories, from `resolveJvmSourceRoots`.
 * @param workspaceRoot - Absolute project root, for the existence check.
