 The `Pcap modality` column in the tables below specifies which network-layer file is present on disk per bundle: `pre-term TLS` means `pcap_pre_termination.pcap` is retained (encrypted TLS frames; IP/TCP headers visible); `none` means the raw `packets.pcap` was dropped and no pre-term variant exists (`BundleFiles.packets_pcap=False` in the manifest).
