Domain, security and integrations

Technical guide

The minimum technical contract for publishing, connecting providers, protecting data and keeping a verifiable exit.

This guide is for: Technical provider, IT, data protection and operations
Expected outcome: Every dependency has an owner, environment, credential, test and rollback procedure.

Domain, DNS and publishing

Publishing starts with known ownership and ends with a tested rollback.

1.1
Record owner, provider, access, current DNS records and change window.
1.2
Reduce TTL where appropriate and validate certificates, email and routes before switching traffic.
1.3
Keep the previous configuration and an explicit rollback criterion.

Architecture should reflect agreed purpose, access, retention and deletion.

2.1
Map data, systems, processors, locations and export flows.
2.2
Separate environments and secrets; apply least privilege, logging and rotation.
2.3
Define backups, restoration, incidents and deletion with owners and tests.

A connection is real only when provider, scope and failure have been tested.

3.1
Document API, environment, credentials, limits, retries and idempotency.
3.2
For payments, agree provider, webhooks, reconciliation, refunds and disputes.
3.3
Label as demonstrative or planned any connection that has not been implemented.

Continuity needs documentation another person can operate, not only the builder.

4.1
Hand over architecture, domains, accounts, dependencies, monitoring and agreed runbooks.
4.2
Test support and recovery with a realistic case before acceptance.
4.3
Agree export, access revocation, deletion and verification on termination.
