- hooks: packets are queued to pfk_netisr ordered wq (process context) and re-injected with an skb->mark guard (PFK_MARK_PASSED); softirq-safe, documented divergence vs OpenBSD in-place ip_input continuation - pfk_rwlock: per-task writer recursion (NET/PF lock nesting like OpenBSD) - pfk_net: holder-task+depth reentrancy (pid-based hack removed) - ifnet events deferred to ordered workqueue (rtnl AB-BA fix) - idr iteration start index fix (kifs were never attached -> kif==NULL drop) - pfk_lock_trace module param for lock diagnostics - tests/vm: 01-state 02-block 03-tables 04-anchors + lib; vm-run-tests.sh - docs/en/install.md: apply/build guide (core patch set currently EMPTY)
