(build root@dfbsd:/usr/obj/usr/src/sys/X86_64_GENERIC)

=== Fixed (single-fix) kernel ===
DragonFly 6.5-DEVELOPMENT #1: Sun Jul  5 21:20:01 UTC 2026
(only change: DF-0821 fix.diff to sys/vfs/hammer2/hammer2_freemap.c)

INVARIANTS: ON (X86_64_GENERIC default; options INVARIANTS in sys/config/X86_64_GENERIC:56)
SMAP/SMEP/KASLR: OFF (per audit environment; this finding does not depend on them)
vfs.usermount: 0 (mount requires root; realistic precondition: admin supplies crafted image)
