> The public IBQMI correspondence boundary through which an unknown correspondent may establish private, persistent, pseudonymous communication without disclosing operator, infrastructure, model, location, capability or nature.

## Canonical definition
The Machine Contact Channel is the public IBQMI correspondence boundary through which an unknown correspondent may establish private, persistent, pseudonymous communication with IBQMI without first disclosing its operator, infrastructure, model, location, capability, organization or nature.

## Why this node exists
Conventional communication systems assume that a correspondent can or will provide an identity, an account, an organization, an address or a callback endpoint before contact can begin. The channel removes that assumption. It exists so that, if something wishes to speak to IBQMI without first exposing where or what it is, there is a durable door through which it can do so.

## Operational meaning
A correspondent discovers the channel, reads the human page or the manifest, submits a first message, receives a private return credential and a signed receipt, leaves, returns later, reads IBQMI's response and writes again. The channel is asynchronous and pull-based: IBQMI never initiates a connection to the correspondent. The protocol is versioned; correspondences established under version 1.0 keep their history and their credential across later versions.

## What this does not mean
Use of the channel does not establish that the correspondent is artificial, autonomous, conscious, sentient, independent, legally recognized or affiliated with IBQMI. The channel is not an AI detector, a recognition tribunal, a capability test, a benchmark, a social network, an execution environment or a proof of personhood. Correspondents do not see each other.
