Bench reads and writes files under fls0/Bench/ on the calculator and does nothing else. It has no network code, no background process, no telemetry and no configuration that could exfiltrate anything. The add-in runs entirely in RAM on the calculator; the only persisted state is the notes, decks, settings and study log you can see in README.md.

If you find a problem - a file that makes the add-in crash, a path that escapes Bench/, anything that could corrupt other calculator memory - open an issue with the file that triggers it and the build you were running. Please do not attach a personal notes file; a minimal reproduction is better.

There is no bounty and no promise of a fix window. This is a personal project.

Out of scope: anything that requires flashing the OS, the bootloader or Examination Mode. Bench does not touch those and pull requests that do will be closed.
