Interoperability
Shared rules make participation interoperable
Protocol interoperability depends on one formal interaction grammar rather than local conventions hidden inside individual systems.
Shared grammar
Systems can only interoperate through a common rule model
Interoperability comes from shared participation structure, shared references, and shared expectations about interaction meaning.
Why shared grammar matters
Without shared grammar, one system’s participation act may be unreadable or structurally invalid in another.
What interoperability requires
Interoperability requires shared message structure, references, lifecycle logic, and compatible validation.
Why local conventions fail
Local conventions do not create durable cross-system participation unless the rule layer is shared and explicit.
What interoperability depends on
Shared structure keeps participation readable
Protocol interoperability depends on enough shared structure that separate systems can interpret participation acts without guessing at private rules.
Shared envelope
Systems need to recognize the same message form so participation can be parsed consistently.
Shared references
Systems need compatible ways to identify participants, task context, lifecycle position, and version posture.
Shared validation
Systems need compatible validation logic so one side does not treat as valid what the other rejects structurally.
Shared transitions
Systems need a compatible view of lifecycle movement so participation carries the same operational meaning.
Boundary clarity
Interoperability is not sameness and not outcome agreement
Interoperability requires shared rule logic, not identical products or identical results.
What interoperability means
Separate implementations can read, validate, and place participation within the same rule model without depending on private conventions.
What interoperability does not mean
It does not mean every product becomes identical or every participation flow ends in the same decision or output.
Why the distinction matters
Protocol defines the shared interaction layer without eliminating product differences or governed resolution logic.
