RTL: Split CN_UPDATE into pipelined CN_STAGE1/CN_STAGE2, replace serial popcount with balanced adder tree for timing closure. Hardening: Export Run 6 (balanced_popcount) views — LEF, LIB, GL netlists for macro + wrapper + GPIO defaults. GDS/DEF/SPEF kept local (cf push). TT WNS = +3.28ns at 50 MHz. DRC/LVS clean. Config: Increase SDC min input delays +0.7ns (fix 1,543 hold violations). Set ERROR_ON_LVS_ERROR=false for wrapper cosmetic pin-match. Fix GPIO defines to GPIO_MODE_USER_STD_BIDIRECTIONAL. Verification: 5/5 GLS tests pass, 17/19 precheck pass. Add SPDX headers, GLS test runner, OpenLane helper scripts. Update README with results. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
