+/// <summary>
+///     Options that drive an <see cref="IRsLogixImporter"/> run. Captures the few knobs that
+///     reasonably differ between projects without forcing a dedicated subclass per import shape:
+///     scope filter (Global vs. Local:N), maximum rows to keep (defensive cap on suspicious
+///     exports), and whether to silently drop malformed rows or surface a parse exception.
+/// </summary>
+/// <remarks>
+///     <para>
+///         <see cref="ScopeFilter"/> matches the optional <c>Scope</c> column on RSLogix CSV
+///         exports — "Global" tags live at the project root; "Local:1" / "Local:2" / etc. are
+///         scoped to ladder file 1, ladder file 2, etc. When non-null, only rows whose
+///         <c>Scope</c> value matches case-insensitively are emitted; rows with no <c>Scope</c>
+///         column are treated as Global.
+///     </para>
+///     <para>
+///         <see cref="IgnoreInvalid"/> defaults to <c>true</c> — RSLogix exports tend to carry
+///         the occasional cosmetic row (single-letter alias, comment-only rows, blank lines)
+///         and the v1 contract is "import what we can, log a warning for everything else".
+///         Set to <c>false</c> to fail-fast on the first malformed row (useful for CI lint).
+///     </para>
+/// </remarks>
