____15DS — The Act as a State Transition: Protocol Interpretation of the GVB

Trigger S6, Finding AP8

From the first use follows the dual interpretation of the terms, which is what makes verifiability comprehensible in the first place:

A GCPN is a form of protocol. In the GCBoK, with Compliance as the main topic, there is often talk of shareholder meetings with resolutions that are summarized in a GVB: The GVB is the protocol — the Acts are the resolutions. And: An Act also describes the change between two states.

The Dual Interpretation

Term Protocol Interpretation State Interpretation
GVB the protocol of the meeting (summarizing document) can contain many Acts (resolutions)
Act the individual resolution describes the change between two states (Before → After)
GCPN the process protocol of the transaction (creation, signing) documents the state transitions in a revision-safe manner

The Act between Two States

An Act (resolution) is a state transition:

Zustand VORHER                          Zustand NACHHER
"Anrufungsauskunft-Auftrag              "Auftrag aufgehoben; Pauschalen
aktiv (GVB 260819 TOP 6.3)"             werden ab 01.09.2026 ausgezahlt"
        │                                       ▲
        └────── ACT (TOP 1: Aufhebung) ─────────┘
                    │
              (revisionssicher: referenced_doc.sha256,
               events_result, Git-Historie)

The Act is anchored by three levels of evidence:

  1. Before — via the SHA-256 chain (Referenced-Doc, Sidecars): the state before the Act is verifiable as a document.
  2. After — via the flags expression (events_result, e.g. 11) and the embedded artifact: the new state is described deterministically.
  3. Chronology — via the Git history of the container: which steps were added when is recorded in the commit log in a revision-safe manner (commit hash = proof of integrity).

In the Schema

"actor": {
  "actor_id": "PARTNER-ORG",
  "kind": "gvb",
  "…",
  "act": {
    "kind": "shareholder-meeting-resolution",
    "note": "Das GVB ist das Protokoll der Gesellschafterversammlung — die Acts sind die Beschlüsse. Ein Act beschreibt auch die Veränderung zwischen zwei Zuständen (Vorher/Nachher); der GCPN dokumentiert genau diese Zustandsübergänge (Events als Flags, referenced_doc.status) revisionssicher.",
    "acts": [ … ]
  }
}

referenced_doc.status shows the state of the Referenced-Doc after the transaction (immutable after signing); events.events_result shows the steps traversed; summary.immutable_from shows the point in time of the immutable transition.

GVB ≠ GCPN — The Roles in the Process

Artifact Character Content
GVB (Referenced-Doc) the protocol — is signed resolutions (Acts) as wording
GCPN container the process protocol — remains mutable signature doc, events flags, summary, verification manifest

The container accompanies the transaction (creation → signing); the signed Referenced-Doc becomes immutable afterwards. The container continues to document the process — the Git history is the proof.

Research Gain Protocol (AP8)

AP Finding Implementation
AP8 Protocol/state interpretation was missing from the model actor.act (kind: shareholder-meeting-resolution, acts[]) + referenced_doc.status + summary.immutable_from
