Captain Bob, 2026-11-07: "Kernel is 4.0.0. This is our first alpha release." LITHOS_VERSION 2.1.0 -> 4.0.0-alpha.1; the engine (VERSION) stays 3.2.0. The 4.x line is a working line (even major); v3.0.0 is no longer the next number, and an LTS line takes the next odd major when FABRIC-3.5.md XXX.5's criteria are met. Recorded in kernel/Makefile's versioning policy. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01GE3SDvQn5EoxdGufk84zz2
