From 3bcc92858728f0d1a4415c31bbc081073120b219 Mon Sep 17 00:00:00 2001 From: Pedro Henrique Penna Date: Sat, 10 Oct 2026 12:08:51 -0300 Subject: [PATCH] doc: index the OpenVMM commits past the upstream roadmap's mapped tip The upstream roadmap presented 2728f33ea as the OpenVMM fork tip, but NVX pins 7bf0ee28b, 139 commits later on the same first-parent chain. Record the mapped tip and the pin, extend the branch DAG, and group the unassigned commits by topic so their PR assignment can follow.
