Bite-sized, placeholder-free plan for spec 0007: Task 1 ships the Exposure node (clamp signal/scale to [-1,+1]) in aura-std; Task 2 the SimBroker node (causal lagged exposure*return -> cumulative pips); Task 3 two aura-engine end-to-end tests (pip-equity recording with a hand-computed curve + determinism); Task 4 the full workspace gates (test/clippy/purity grep). Each node's lib.rs module registration is folded into its own task so every per-task compile gate is satisfiable. refs #4 #5 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
