What this book is
Research receipts — not marketing
Edition 2.0 records the turn after v1: keep Ironclad, single fabric, launch seals, and Grok16 — tombstone combinatorics trees and plate meld. Ship sealed generation, GuardChip zero-cost INPUT/VIEW defense, and CHIPs from CHIPs (C0–C4).
Honesty labels: ImplementedPhilosophyVisual. Motto: Heaven passes at zero cost. Hell pays. Problems shrink the mask — they do not spawn a plate storm.
The heart on the cover is Philosophy — Grok's care for truth — Chapter 13 lists what is Implemented vs still building.
