Answer
For the good ending, protect your save, avoid careless hostile choices, and read quest branches before committing.
A complete good-ending route is not published as final on this site yet. The safe answer is to protect your save, avoid careless hostile actions, and read quest choices before committing.
Because choices can be permanent, do not rush NPC branches if you care about an ending. Track major decisions, reputation changes, and faction outcomes.
When a good-ending route is confirmed, it should include exact prerequisite quests, NPC choices, lockout warnings, and final trigger steps.
