CESNET-TLS-Year22 — canonical flow parquet

CESNET-TLS-Year22 (507,739,073 TLS flows over the full year 2022 from the CESNET2 backbone, 180 service labels) converted from the cesnet-datazoo ORIG HDF5 database into a canonical flow-record parquet schema: 357 daily parquet files, exactly 507,739,073 rows, 39.5 GB zstd.

—`label_service` carries the authoritative APP label decoded from the PyTables enum embedded in the source database; servicemap.csv (included) documents the services. label_binary is "unknown" throughout — backbone traffic was never security-audited, and this conversion refuses to call it benign.
—PPI sequences (per-packet inter-arrival times, directions, sizes, push flags; ≤30 packets) are trimmed to their true PPI_LEN — storage zero-padding never masquerades as measurement. Packet-size/IPT histograms, bidirectional counters, TCP flag bitfields, and flow end reasons are preserved.
—Missing dates match the upstream collection gaps (2022-01-28..30, 2022-12-12..13, 2022-12-29..31).
