Auto-design agent for chip-level electrical routing of a 32-net PhotonForge projector circuit (16 AMZIs, each with two thermo-optic phase shifters that need a DC route to a bondpad). No cloud simulation; DRC violation count is the fitness signal. design.py ships with the iter-1 naive Manhattan baseline that produces 192 DRC violations (30 heater + 162 route × route + 0 pad × pad). Adds tools/ harness with the routing arena (grid maze + Manhattan runners, BFS / A* / Bundle / Rip-Up / Hybrid algorithms), the projector circuit fixture, and DRC scoring. route.py replaces simulate.py since this branch does layout, not physics. See README.md for the full design knobs and iter-1 baseline metrics. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
