Troubleshooting

• Inputs and scientific fits: import errors, missing dates, insufficient sampling, ambiguous harmonics, and failed fits.
• Application and exports: stale results, slow simulations, locked files, and a blank desktop window.
• Snapshots: verification failures and safe restore rehearsal.

An input refusal protects the meaning of the result. Correct the named input and run again; do not replace missing evidence with a more permissive setting merely to obtain a number.
