- Q16_SCALE: float → int in lib/q16.py (int // float returns float, breaking Q16_16 integer contract in gccl_waveprobe, vcn_famm_transport) - qr_spatial_hash.py: sys → _sys (only _sys was imported) - Add missing 'from pathlib import Path' to 7 files that use Path() without importing it: test_fpga, compare_tier1_vs_tier2, generate_avm_gold_trace, burgers_triad_core, hot_path_cold_path, sabotage_prevention, generate_diat_tables - hot_path_cold_path.py: also add missing 'import sys' Co-Authored-By: Allaun Silverfox <bigdataiscoming+9i37y6j2@protonmail.com>
