"""A standalone-only profile does not mark its files standalone.

Per-file mode separates the two builds of a dual profile. ares, clk,
primehack, jgenesis and five Switch emulators repeated `mode: standalone`
on all 226 of their files: the gap analysis skips such a file, so
cross_reference reported 0 undeclared files where verify --standalone
counted 118 for clk alone, and a platform listing the emulator without
standalone_cores dropped them from its pack.
