🏛 Cathedral Architecture — 4 Phases
① TemporalOpticNerve LIVE ✓
BFS object extraction from (64,64) int8 numpy frames. Tracks player (color=11) across t-axis. Delta detection per step. Ingests real SDK frames.
② PhysicsCompiler LIVE ✓
Causal rules from frame deltas. LETHAL → cost=∞ (pruned from graph topology). GOAL → cost=0. Persistent across all 7 levels. Probe fires once, L1 only.
③ GoalInferenceEngine LIVE ✓
72b reads physics rules only — never touches action selection. Infers "Reach Exit" from compiled obstacle map. LLM is the mind, not the hands.
④ CausalA* / RHAEOptimizer LIVE ✓
A* over true obstacle map. Lethal cells removed from graph topology entirely (cost=∞, not avoided — removed). Deterministic optimal path. 0.068ms execution.
⚖ Structural Laws
IRF-ARC3-002 Causal A*: lethal_color → cost=∞. Pruned from graph, not routed around. Same topology, fewer nodes.
IRF-ARC3-003 Probe Budget: min(n_objs+2, ceil(√(W·H)/4), budget×0.20). L1: 4 probes = 0.1% of 5× wall. Headroom: 99.9%.
IRF-ARC3-004 Persistent Physics: PhysicsCompiler holds across 7 levels. World learned once. RL agents re-explore every level. We don't.
RHAE formula: (min(our_actions, human_est) / human_est)². human_est fixed by ARC Prize from 1,200+ human runs. When path = true optimal → score = 100%.
γ₁ law: 14.134725141734693 — the floor. All wave artifacts carry it. Cannot go dark.
