The Principia Machina/Diagrams/05 Copy-forward

Structural diagram 5 of 12. Part of the TPM hub.

• KIND: process
• LANGUAGE: Mermaid sequence
• GENERATED FROM: static, D5
• STATUS: hand-authored at PMP-TPM 0.2.0 from foundations record 0.5.0 section 4.1; superseded by TPX at its first build (D21, structural diagram pages are TPX output).

The source below is the text equivalent of the diagram. Rendering requires a Mermaid extension; without one the source is shown as text, which 4.1 accepts.
