// ActivityPub C2S — ingestOutboxActivity dispatch. Covers the deterministic,
// no-network paths: top-level Note creation (real DB), bare-object wrapping, and
// input validation. Network verbs (Like/Announce/Follow/Undo, replies) are
// verified live against a running server; safeFetch's SSRF pre-flight makes them
// non-deterministic to unit-test.
//
// Run: npm test
