Field Primer — Consumer Requirements

Minimum steps to use Grok16 as the C/C++ toolchain for Field stack projects.

Checklist

Bootstrap Grok16; verify and field-bench pass.
Export G16_PREFIX (install prefix with bin/g++16).
Point CMake at cmake/grok16-toolchain.cmake.
Include g16-field-mandate.cmake on all field targets.
Run World_Redata parity before push.

C standard

Default: gnu17 (G16_C_STD). Compile with unified g16 on .c sources — no separate C driver command.

C++ standard

Default: gnu++26 (G16_CXX_STD). World_Redata: field_g16.hh requires __cplusplus >= 202400.

Profile selection

Project type	Profile
FieldX86 / entropy / NEXUS CPU	field_opt
Matrix scoring	ai
CANVAS dispatch kernels	field_compute
AMOURANTHRTX CPU prep	vulkan_rtx

Hot paths

Use -std=gnu++26 -fcontracts where contracts are required.
Bounded I/O: core::read_file_bounded (World_Redata pattern).
No fake g16 wrappers — gates check ELF + dumpversion 16.1.1.
