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

.. py:module:: sequence_expansion

.. autoapi-nested-parse::

   Position-safe expansion and reduction for semicolon-separated protein sequences.







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

.. py:class:: ExpandedSequence

   One protein-sequence candidate from an input row.


.. py:class:: SequenceExpansionPlan

   A positional mapping from input rows to split protein sequences.


.. py:class:: TargetPredictionUnit

   One flattened engine input unit after sequence/substrate adaptation.


.. py:class:: TargetExpansionPlan

   Position-safe mapping between engine units and original reaction rows.


.. py:function:: split_sequence_list(value: Any) -> list[str]

   Split a semicolon-separated protein list, trimming empty fragments.


.. py:function:: count_multi_sequence_rows(values: Iterable[Any]) -> int

   Return the number of rows containing more than one protein token.


.. py:function:: reduce_sequence_predictions(*, plan: TargetExpansionPlan, target: str, child_predictions: Sequence[Any], child_sources: Sequence[str], child_errors: dict[int, str] | None, child_details: Sequence[str] | None, reaction_count: int) -> ReducedSequenceResults

   Reduce flattened sequence/substrate child results back to input rows.
