:py:mod:`bw_timex._lci_cache`
=============================

.. py:module:: bw_timex._lci_cache

.. autoapi-nested-parse::

   Module-level cache for background unit LCI matrices.

   This cache persists across :class:`~bw_timex.TimexLCA` objects within a single
   Python session / ``bw_timex`` import (e.g. one Jupyter notebook kernel).

   Only *stable* background process identities are stored here: keys of the form
   ``("db_code", db, code, modified)``, where ``modified`` is the background
   database's ``modified`` token. Editing a background database bumps that token,
   so stale entries are automatically missed instead of silently reused.

   Unstable keys (the time-mapped ``activity_id`` and the per-run
   ``temporalized`` database) are deliberately kept per-object by the
   :class:`~bw_timex.dynamic_biosphere_builder.DynamicBiosphereBuilder` and never
   reach this module-level cache.
