CPU Compatibility

The distribution binary is built for compatibility mode, so it runs on a wide range of x64 and ARM64 CPUs. On very old hardware or restricted environments, you may see errors like:

• Illegal instruction
• SIGILL
• Operation not supported (when the binary hits an unsupported CPU instruction)

1. Verify the binary — run ./identity-scribe-* --version. If this fails, the CPU may not support the baseline instructions required by the compatibility build.

2. Check your CPU — the compatibility target excludes newer instruction sets (e.g. AVX2, AVX-512). If you run on an older x64 CPU (pre-2011) or a constrained VM/container, you may hit limits.

3. Workarounds:

   • Run on a host that meets the System requirements.
   • Make sure you run the binary that matches your target platform/architecture (for example, x64 vs ARM64).
   • If startup still fails, contact support and include the exact error output plus your platform details (uname -m, container base image, and virtualization environment).
