| The platform moves all external network connections to the outermost boundary of the system before any data reaches the core processing rings. This architecture prevents common network-based attacks from reaching the financial ledgers and structured records held in Ring 2. | The platform moves all external network connections to the outermost boundary of the system before any data reaches the core processing rings.

| ## The problem with deep ingest | ## The problem with deep ingest |
| Standard server configurations process incoming internet traffic — email, HTTP, external API calls — inside the same execution environment that holds core data. A vulnerability in any ingest pathway grants an attacker access to the same memory space as the core records. Isolation cannot be added retroactively once a process has shared-memory access to another. | Standard server configurations process incoming internet traffic — email, HTTP, external API calls — inside the same execution environment that holds core data.

| The platform positions all ingest processes at the physical and logical edge of the system. No inbound internet payload crosses into Ring 2 until it has passed through the Ring 1 boundary layer. Ring 1 is implemented as a set of Model Context Protocol (MCP) server processes, one per ingest channel (email, filesystem, people records, external input). | The platform positions all ingest processes at the physical and logical edge of the system.

| ## Effect on audit integrity | ## Effect on audit integrity |
| Because raw payloads are sanitized at the boundary and the cleaned records are what Ring 2 processes, the audit ledger in Ring 2 reflects what the system acted on — not what arrived at the wire. This separation is a precondition of the WORM ledger design: the ledger records clean, validated events, not raw network traffic. | Because raw payloads are sanitized at the boundary and the cleaned records are what Ring 2 processes, the audit ledger in Ring 2 reflects what the system acted on — not what arrived at the wire.
