Governed Growth, Part 4: Multi-Model, Governed, and Boring
The finale of the series: the mature end-state the first three parts build toward. When every server-side capability's trust boundary is a decision on record—the deployment tier you chose, the toggle you set, the contract you signed—saying yes to another team stops being a risk assessment and becomes a lookup. Fine-grained capability governance is what buys you safe expansion. Maturity, not lock-in. Boring, in the way a well-run system is boring.
