# Positives are REAL libsql/Turso credential shapes, not a synthesized
# regex-satisfying body. A bare numeric host (`libsql://78167825`) is correctly
# suppressed as numeric noise on every path, it fires 0 matches direct AND
# through decode-through, so it was a fake positive (Law-6) that only passed
# the primary regex. These fire on the direct scan and survive base64/hex/url
# decode-through (verified against the compiled scanner).
