 - Adopted the shared `Ast::Merge::Layout` contract for top-level RBS declaration gaps, including shared layout compliance coverage across native and tree-sitter-backed paths
 - Preserved destination-owned docs and leading comments through template-preferred matched declarations and recursively merged members across the native, Rust, and FFI-backed validation paths
 - Preserved or promoted comments for removed destination-only declarations when `remove_template_missing_nodes: true` is enabled, while keeping destination-relative ordering stable in the documented Phase 2 contract
+- Rebased `Rbs::Merge::FileAligner` onto the shared `Ast::Merge::FileAlignerBase`, leaving RBS-local declaration payload keys plus freeze-node alias/signature and sort behavior in the RBS layer
 - Adopted `Ast::Merge::TrailingGroups::AlignmentSort` for shared template-only RBS declaration ordering while preserving the existing freeze-block-aware destination sort contract
