## Overview
Compiler-driven sub-microsecond feedback control stack for scalable trapped-ion quantum experiments. Covers Python-embedded DSL, six-stage transpilation pipeline (CFG, SSA, liveness, register allocation), cross-board synchronization with <700ns latency, and deterministic distributed board-level programs.

## Key Findings
As trapped-ion quantum computing scales to larger qubit registers and more complex control protocols, classical control systems face a fundamental tradeoff: sub-microsecond board-level feedback requires tight hardware coupling, whereas maintainability and extensibility require clean, modular software abstractions. QuCtrl-BELL resolves this by decoupling control flow from hardware state data. A Python-embedded DSL is lowered through a six-stage transpilation pipeline covering CFG construction, SS...
