//! End-to-end tests for kind:30176 team events (NIP-AP).
//!
//! These tests verify the relay accepts and addresses team events the same way
//! it does personas:
//! - Accepts a valid team event and queries it back by NIP-33 coordinate.
//! - Enforces NIP-33 replacement semantics (same d-tag, newer timestamp wins).
//! - Honors a NIP-09 a-tag tombstone, removing the team coordinate.
//!
//! The team `d`-tag is the team's stable id (a slug-like string), not a 64-hex
//! pubkey — it exercises the generic parameterized-replaceable path that
//! enforces only `D_TAG_MAX_LEN`, distinct from the persona slug envelope.
//!
//! # Running
//!
//! Start the relay, then run:
//!
//! ```text
//! RELAY_URL=ws://localhost:3000 cargo test --test e2e_team -- --ignored
//! ```
