This commit addresses several security and functional issues in `copyables/entrypoint.sh`: - **Password Truncation:** Quoted `$username` and `$password` variables when calling `adduser`. Previously, passwords with spaces were truncated due to shell word splitting. - **Command Injection/Globbing:** Added `set -f` (disable globbing) around dynamic command execution for `VPNCMD_SERVER` and `VPNCMD_HUB`. This prevents accidental or malicious file path expansion if arguments contain glob characters like `*`. - **Command Loop Fix:** Fixed logic that silently ignored multiple semicolon-separated commands in `VPNCMD_*` variables. Now correctly iterates over the array to execute all provided commands. Added `tests/verify_password_fix.sh` to verify these fixes and prevent regression. Added `.jules/sentinel.md` to document the security learning.
