TRANSFER STANDARD: cloc 2.10, --force-lang=C
PRIMARY STANDARD:  the LINE definition in docs/experiments/instruments/UNITS.md
REFERENCE:         hand enumeration in reference/*.WORKING

fixture        known                  cloc (blank,comment,code)
ref_lines.el   3,7,8                  3,7,8   AGREES
ref_wrong.el   0,3,1                  0,3,1   AGREES

Both fixtures agree. cloc is a valid transfer standard for the LINE unit.
Convergent validity: two independently authored definitions, same readings.
