A platform is not just a cluster. It is a set of promises about how applications are deployed, secured and operated.
Architecture Decision Records (ADRs) record why a choice was made, its trade-offs and who can revisit it. Contracts define what the platform must guarantee to its consumers.
Together, they keep engineering honest: components can change while expectations remain explicit. This matters for long-lived infrastructure, where teams, vendors and technologies inevitably evolve.
We use this mindset to make platform changes reviewable, testable and understandable beyond the team that originally built them.
