unsupported project announcement kind

Error message

unsupported project announcement kind

What it means

build_project_owner_announcement_events only signs project-owner announcement templates whose kind is 30617 (NIP-34 git repository announcement) or 30621 (project announcement). Any other kind is rejected with this bail because the relay has no handler that will accept or process such an announcement.

Solutions

1. Set the template's kind to 30617 (repo announcement) or 30621 (project announcement)
2. Cross-check the canonical kind registry in crates/buzz-core/src/kind.rs before inventing kind values
3. Regenerate the config from a current example config instead of hand-editing

Example fix

# agent config
# before
project_owner_announcements:
  - kind: 30078
    tags: [["d", "my-project"]]
# after
project_owner_announcements:
  - kind: 30621
    tags: [["d", "my-project"]]

// Preflight templates before harness startup
const SUPPORTED: &[u16] = &[30617, 30621];
for t in &config.project_owner_announcements {
    if !SUPPORTED.contains(&t.kind) {
        anyhow::bail!("template kind {} not in {SUPPORTED:?}", t.kind);
    }
}

fn is_supported_announcement_kind(kind: u16) -> bool {
    matches!(kind, 30617 | 30621)
}

When it happens

Trigger: Agent/harness startup configuration contains a project_owner_announcements template entry whose kind is any value other than 30617 or 30621 (e.g. a copied 30078 chat kind or a made-up kind), and startup reaches build_project_owner_announcement_events.

Common situations: Hand-edited harness config or a template copied from a different event type; a buzz-acp version change that narrowed the allowed kinds while stale config is still deployed.
