Learning from TPA's ADR model
In February 2026, anarcat from the Tor system administration team (TPA) published a post titled \"Keeping track of decisions using the ADR model\".
After reading it, we felt it offered a very practical way to think about proposals, decision-making, and how to write things down so that people can actually find and understand them later.
This post is not a translation of the original article. Instead, it is our own summary and reflection on:
- what problem TPA was trying to solve with ADRs,
- what they actually changed in their process,
- how other projects handle proposals and decisions, and
- how this connects to the context we are familiar with.
