Required confirmations

• I searched existing issues and did not find the same reproduction.
• I have already attached, linked, or privately sent the sample using the selected method.
• I understand that screenshots and renamed file extensions do not replace a real sample or runnable reproduction.
• Any public attachment is sanitized and safe to redistribute for regression testing.

Thanks for the report. A reproducible artifact is required for bugs: attach a public/sanitized sample, add a public minimal-reproduction link, or send the private sample to admin@flyfish.dev and record the date and filename in the issue. Screenshots are helpful, but they cannot replace the sample.
