# DF-0602 — PoC: (none — file is orphaned/non-compiling)

No PoC can be built today. `sys/netgraph7/ng_source.c` is not listed in
`sys/conf/files` and has a compile error at line 742 (`ifq` undeclared;
should be `ifsq`). The file is dead, non-compiling code.

See `findings/DF-0602-ng7-source-get-counter-arglen.md` for the analysis
and the fix diff.
