Publication boundary
Open enough to integrate. Restrained enough to operate safely.
Documentation is divided by operational risk, not by convenience.
Partner
Assigned endpoints and credentials, authenticated test environments and model-specific UAT fixtures.
Internal
Production secrets, tenant data, private logs, provisioning records and unrestricted service tooling.
