• snapshot_enabled: Virtual A/B snapshot status
• vabc_enabled: Virtual A/B compression enablement
• vabc_compression_param: Compression algorithm (lz4, gz, etc.)

• misc_info.txt uses accurate VABC settings from Stock ROM:
  • virtual_ab_compression_method
  • virtual_ab_cow_version
  • virtual_ab_compression_factor
