…eaves Regression coverage for PyAutoFit#1441 (traced values leaking into pytree aux data), the autofit half of the PyAutoLens#678 phase B cluster gradient failure. Fails with UnexpectedTracerError on pre-fix autofit. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01DnTmLoJjJgMTze5uAbg1Jd

Regression coverage for PyAutoLabs/PyAutoFit#1441 — the autofit half of the PyAutoLens#678 phase B cluster gradient failure. JAX-using tests live here per PyAutoFit#1247.
The script builds a model whose class derives an attribute in
__init__from a prior parameter, then asserts (1) the flattened instance carries no tracers in aux data and (2) acustom_jvpwhose rule re-reads the derived attribute inside its ownjax.jvpdifferentiates cleanly with the exact gradient. Verified to fail withUnexpectedTracerErroragainst pre-#1441 autofit and pass after.Merge after PyAutoLabs/PyAutoFit#1441.
