The 2026-08-06/07 handoff pass carried the dark-horizon draft to a book a developer builds from: the complete 12-rule Rulebook (Boop · Goop · Move, 1HKO, the chain, the forever goop counter), the numeral series i→x with a per-release fun-gate, Flutter + Firebase locked with match-is-its-move-list architecture (ARCHITECTURE.md shipped beside the book), the preview contract (first tap foretells the whole chain, second commits), and the book·ICP·GTM triangle cross-linked. Rulebook re-set as twin engraved stone tablets. Six items in the lock queue (wordmark, mono-vs-Bungee display A/B, game-i motion values, the x-reskin call).
