 ## interferometer-analysis-fitexception
 - issue: https://github.com/PyAutoLabs/PyAutoLens/issues/606
-- status: library-dev
+- status: awaiting-input
+- question: https://github.com/PyAutoLabs/PyAutoLens/issues/606#issuecomment-4969024309
 - worktree: ~/Code/PyAutoLabs-wt/interferometer-analysis-fitexception
 - autonomy: supervised (--auto launched 2026-07-14; plan approved in-session; no heart-ack) — bug cap; ship sign-off parks with a question
 - note: resolves release-validation tail item G (PyAutoHeart#72). NOT jax-0.10.2 drift — interferometer log_likelihood_function lacks the imaging analysis's NumPy-path try/except→FitException guard, so a non-PD inversion (np.linalg.cholesky at abstract.py:743) crashes the search instead of resampling; JAX path masks it via NaN. Fix = mirror imaging/model/analysis.py:132-144. Reproduced on jax 0.10.2 with PYAUTO_DISABLE_JAX=1.
+- state: fix implemented + validated in worktree (UNCOMMITTED); diff in the question comment. Validation: numpy-path model_fit.py now completes (was LinAlgError crash); 22 interferometer unit tests pass; jax branch unchanged. Parked for ship sign-off (A ship narrow / B expand to point_source / C hold). On A/B → run ship_library.
