TLSv1.2 key exchange uses the named mechanisms and cryptographic algorithms (ephemeral Diffie-Hellman, elliptic curve variants), session resumption is bounded so that a resumed session does not extend key lifetime indefinitely, and session renegotiation is used to update the session key of long-lived connections at a maximum interval or data volume, with the secure renegotiation extension mandatory.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
