Phase 0 Infrastructure Notes

Private notes on preservation boundaries, cleanup decisions, and the MCP operating model.

Preservation boundary

The retained assets are connection and infrastructure primitives, not legacy product state.

Retained

OCI compute instances
Autonomous Database services
Database wallets and TNS configuration
Object Storage bucket/configuration path for possible future use
Domain and routing relationships
Secure MCP tunnels

Disposable

Legacy Blackdeck and ByteCosmos application code
Existing database tables and data
Generated datasets
Legacy models and logs
Old schedulers
Old UI and site design
Object Storage file contents

Operational decision

Blackdeck and jintaechoi.com may share one physical OCI VM, but they are to be operated as separate logical services with separate users, directories, runtime services, configuration, and deployment boundaries.
