Runtime Chat binding state has no account owner

Error message

Runtime Chat binding state has no account owner

What it means

RelayState::validate requires that a binding state which contains any bindings also records an account owner via owner_scope_fingerprint. Bindings are scoped to an owner; without that fingerprint the state cannot attribute its bindings to any account, so it is rejected. An empty bindings list with no owner is allowed.

Solutions

1. Populate owner_scope_fingerprint with the validated owner fingerprint before persisting
2. Clear the bindings list if the state genuinely has no owner (empty state)
3. Restore the owner field from a complete backup of the state file
4. Check the serialization/deserialization path for a bug dropping the owner field

Example fix

// before
let state = RelayState { bindings: vec![binding], owner_scope_fingerprint: None, .. };
// after
let state = RelayState { bindings: vec![binding], owner_scope_fingerprint: Some(owner_fingerprint), .. };

fn ensure_owner_present(state: &RelayState) -> Result<()> {
    if state.owner_scope_fingerprint.is_none() && !state.bindings.is_empty() {
        anyhow::bail!("bindings require an owner_scope_fingerprint");
    }
    Ok(())
}

fn state_is_attributable(state: &RelayState) -> bool {
    state.bindings.is_empty() || state.owner_scope_fingerprint.is_some()
}

match relay.persist_state(&state) {
    Err(e) if e.to_string().contains("no account owner") => {
        log::error!("binding state lost its owner; refusing to persist");
        // re-bind to the current account before retrying
    }
    other => other?,
}

When it happens

Trigger: Loading or constructing a RelayState where bindings is non-empty but owner_scope_fingerprint is None (or None when validate_fingerprint would otherwise run). Raised from persist_state or the duplicate-authority test.

Common situations: Partial/corrupted state files where the owner field was lost; hand-built test state that fills bindings but forgets the owner fingerprint; a serialization bug that drops the owner field when it is null.
