# Greet

Agent connection initiation

Layer: Infrastructure · Category: Primitives

## Mechanism

The initial contact protocol between two [Agent](https://mindscape.world/scapes/bootstrap/Agent.md)s. It involves a cryptographic [Identity](https://mindscape.world/scapes/bootstrap/Identity.md) verification followed by a [CompatibilityCheck](https://mindscape.world/scapes/bootstrap/CompatibilityCheck.md) to establish a shared communication channel. If successful, it transitions the connection state from 'Unknown' to 'Connected'.

## Invariants

- Mutual Auth: Both parties must verify each other.
- No-Op on Mismatch: Connection drops if handshake fails.

## Failure modes

- Authentication Failure: [Identity](https://mindscape.world/scapes/bootstrap/Identity.md) could not be verified.
- Protocol Mismatch: Agents speak incompatible languages.
