GDD v1 (flow-locked hybrid movement, 5 biomes + secret, boss roster), TECH contracts (world API, level schema v0, bus events, manifest law), ART_BIBLE (synthetic scanner look), PIPELINE (MODELBEAST-first, fal gated), PROCESS (PROCITY lane/round law), charters A-F + ROUND1 instructions. Seed code: shell + boot + core (rng/bus/flags) + stub world (peristalsis shader tube, 1 draw / 102k tris, contract-complete) + qa.sh (GREEN). Verified in-browser; evidence docs/shots/laneF/round0_stub_tube.png. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
