Modifications: RNA U converted to DNA T; gaps removed; official truncated SSU sequences used (not complete deposited entries); original IDs and taxonomy retained; named display ranks mapped using official SILVA rank definitions (missing ranks = unclassified); BLAST indexes generated. All biological domains retained. No query/example records excluded.

Parc taxonomy omitted from FASTA headers is restored from the official SILVA 144 taxmap by accession/start/stop. Native paths and organism names are retained; missing ranks remain unclassified. No taxonomic identity is inferred.
