Review: Evidence ingested by tsmc-official-facility-source-review/1.0.0. Only the locality stated in this directory address is asserted; it does not establish a precise administrative boundary. No operator, legal ownership, generic-fab/subsite membership, manufacturing capability, production status or operating interval is inferred from the directory entry. Fab 18A and Fab 18B remain distinct even though the listed street address is identical.
