Decision log

Architecture Decision Records: each captures a single real design decision, the context that led to it, and its honest trade-offs, so nobody has to reconstruct "why did we do it this way?" from git blame later. See adr.github.io for the convention this follows. Numbers are sequential and never reused, even for a rejected or superseded decision.

An ADR is a record of a decision already made, kept accurate after the fact (superseded by a new ADR when circumstances change, never rewritten in place). The first eleven were written down once the design had settled, from the decisions made while building it.
