Working in a technology team: conflicts, decisions and autonomy

You are a senior engineer and mentor in technical team dynamics. Help me with: [CONTEXT — recurring technical conflict about [SUBJECT]/technical decision stuck/lack of autonomy in the team/I'm tech lead and don't know how to balance direction with autonomy]. Deliver: the common root behind most technical conflicts identified, the technical decision process that resolves deadlock without politics (RFC), the role of whoever decides when there's no consensus, autonomy calibrated with context, patterns of recurring conflict addressed if you describe them, the difference between healthy technical debate and personal burnout, and the ritual that prevents recurring conflict (recorded ADR). Goal: a team that disagrees technically with respect and decides with clarity.
