# Minimum Supported CPU Era Configuration
#
# Setting target-cpu enables SIMD auto-vectorization (SSE4.2 on x86, NEON on ARM)
# in key dependencies like tantivy, arrow, datafusion, and bitpacking.
#
# x86_64:  x86-64-v2 — SSE4.2 baseline, supported by virtually all x86 CPUs
#           including Intel Atom/Celeron/Pentium Silver (N-series, J-series, etc.)
#           and AMD equivalents. Excludes only very old pre-2008 hardware.
#           Note: x86-64-v3 (AVX2) was previously used but dropped due to
#           SIGILL crashes on low-power/Atom-class CPUs that lack AVX2.
# aarch64: neoverse-n1 (ARMv8.2-A + RCpc) — AWS Graviton 2 / Ampere Altra, 2020+ CPUs
# macOS:   apple-m1 — Apple Silicon, 2020+ Macs
