Rule 5 of 8 · Chapter II — Data & Delegation
Environment variables for every environment-specific value.
Why this rule exists
A hardcoded URL or team ID works in dev and silently points prod at dev after the first import. Environment variables travel with the solution and get their values per environment — that is the whole feature.
In practice
API base URLs, SharePoint site URLs, Teams IDs, feature toggles: all environment variables, set at import time. Grep the app for tenant-specific strings before every export.
