-- GCL Nanokernel - Genetic Coding Language Core
|
|
--
|
|
-- This is the actual kernel. Linux is just the driver shim.

|
-- Architecture:
|
|
-- Linux Kernel -> Hardware abstraction (drivers, interrupts, timers)
|
|
-- GCL Nanokernel -> Swarm coordination, LawfulLoss, ENE, 89+ modules
|
|
--
|
|
-- Size target: <512KB bytecode (vs 10MB+ Linux kernel)
|
|
-- Verifiable: Each function has Lean LawfulLoss.lean equivalent
|
|

|
|
-- Truth Seal: [ SSS-ENE-TRUTH-2026-05-03 ]
