NEVER Do

• NEVER skip majors — route 1.x → 2.x → latest 3.x → 4.0 before any 4.x minor ladder.
• NEVER skip 4.x hops — upgrade 4.0 → 4.1 → … → 4.7 one minor at a time; stabilize after each hop.
• NEVER claim automatic 1.x→4.x conversion or bit-exact autopilot.
• NEVER treat Domain Skill bodies as migration changelogs — load references/<topic>.md (mirrored from each skill’s references/migration-notes.md).
• NEVER load all module notes at once — only subsystems present in the project.
• NEVER mix server/client Godot minors for high-level multiplayer (especially across 4.2→4.3 SceneMultiplayer protocol changes).
• NEVER choose Mesh “Restart & Upgrade” without VCS backup (4.1→4.2 mesh format).
• NEVER run the 3→4 converter without a full backup (tool does not backup).
