# VWDC-09 Handoff — Federated World Governance, Multi-Champion Arbitration, and Shared Reality Commit Protocols

## Starting state

VWDC-08 defines the reality-facing governance invariant:

$$
RTC
\wedge
Safety
\wedge
Authority
\wedge
Provenance
\wedge
Recovery.
$$

It distinguishes:

$$
\text{many proposing worlds}
\to
\text{one governed commit boundary}.
$$

It proves stale individually valid proposals can violate a global invariant when committed concurrently, while serialized current-state revalidation preserves a checked invariant.

## Objective

Extend this to multiple independent WDC runtimes/twins/organizations sharing one reality or resource substrate.

## Main questions

1. How should proposals from multiple WDC runtimes be transactionally composed?
2. What consistency model is needed for shared reality state?
3. How should incompatible RTC/safety scopes be reconciled?
4. How should global resource reservations avoid stale-check races?
5. How should federated evidence dependence affect arbitration?
6. How should one faulty runtime be quarantined?
7. What is a multi-champion or committee certificate?
8. How should global rollback work when different runtimes have different version histories?

## Desired form

$$
\boxed{
\text{federated proposal graphs}
+
\text{shared state/resources}
+
\text{certificate scopes}
+
\text{atomic commit}
\Longrightarrow
\text{federated governance protocol}.
}
$$

## Prohibitions

- Do not assume locally valid proposals compose globally.
- Do not let consensus replace current-state invariant checks.
- Do not merge incompatible RTC scopes silently.
- Do not permit one runtime to mutate shared reality outside the common commit protocol.
