ewoksxas.fit.tests.test_silx_engine

Tests for the silx fitting-engine helpers (ewoksxas.fit.silx_engine).

Includes the replacement Strip/Snip background theories (formerly in test_backgrounds.py): silx’s stock functions cache their last evaluation in process-wide globals, so snip_bg crashes with a broadcast error when the data length changes between fits (a region-of-interest change) and the cache is shared by every FitManager. Those tests pin the crash regression, the cache semantics, per-manager isolation, and exact parity with the stock silx output.
