How Interaction Works
Structured participation makes interaction durable
Protocol interaction becomes reliable when participation is carried through a shared rule model rather than left inside local, free-form exchange.
Shared rule layer
Clear actor, context, and rule references
A protocol is not there to make interaction sound formal. It is there to ensure that participation can be interpreted beyond one local interface or one local implementation.
Why the layer exists
In the Neura stack, participation should no longer depend on implied authorship, hidden task context, or tacit workflow assumptions.
What Protocol adds
The rule layer introduces a structure that independent systems can parse, validate, and move forward coherently.
Why this matters before later layers
Registry can define who the participants are. Relay can govern how contested outcomes are resolved. Protocol defines the interaction grammar that makes participation durable before either of those later layers take over.
What the rule layer establishes
Participation becomes attributable, checkable, and interoperable
The formal interaction layer matters because it defines the minimum conditions under which participation can move across systems without collapsing into ambiguity.
Attributable
Participation can be traced to a recognizable actor rather than inferred from local context.
Contextual
Interaction is attached to an issue, task, or workflow state rather than floating as disconnected content.
Checkable
The system can evaluate whether participation is structurally complete and valid under the active rule posture.
Interoperable
Independent implementations can interpret the same participation under a shared interaction grammar.
Boundary clarity
Protocol governs interaction structure, not outcomes
The value of the protocol layer comes from keeping its role exact. It defines how participation is formed and interpreted. It does not replace the adjacent layers in the Neura stack.
What Protocol governs
Message form, task context, lifecycle movement, validation, version posture, and the conditions for coherent interaction.
What Registry governs
Recognized participants, declared capability, and durable record continuity across the ecosystem.
What Relay governs
Governed decision resolution once structured participation enters a contested or adjudicative flow.
