============================================

.. py:module:: ml_switcheroo.compiler.frontends.sass.lifter

.. autoapi-nested-parse::

   SASS Lifter (Frontend).

   This module provides the logic to "lift" low-level SASS AST nodes back into a
   high-level `LogicalGraph`. It relies on semantic comment markers (e.g. `; BEGIN`)
   to reconstruct the control flow and layer definitions.

   Updates:
   - Integrates `SassAnalyzer` to parse instructions between BEGIN/END markers.
   - Populates `LogicalNode.metadata` with extracted parameters.
   - **FIX**: Captures top-level instructions (unmapped/raw) into default logic blocks.
   - **FIX**: Preserves register destinations as node IDs for faithful variables.

Module Contents
---------------

.. py:class:: SassLifter

   Reconstructs a LogicalGraph from a sequence of SASS AST nodes.


   .. py:method:: lift(nodes: List[ml_switcheroo.compiler.frontends.sass.nodes.SassNode]) -> ml_switcheroo.compiler.ir.LogicalGraph

      Parses a list of SASS nodes to build a LogicalGraph.

      Captures instructions within BEGIN/END blocks to feed into the Analyzer.
      Captures orphan instructions into individual functional nodes (1:1 mapping).
