//! E2E lifecycle loop test: add → cognify → delete → re-add → re-cognify → search.
//!
//! Verifies that after a hard delete of a dataset, the same content can be
//! re-ingested and re-cognified with identical deterministic IDs (UUID5),
//! and that search works on the re-created data.
//!
//! Required environment variables:
//!   OPENAI_URL, OPENAI_TOKEN, OPENAI_MODEL,
//!   COGNEE_E2E_EMBED_MODEL_PATH, COGNEE_E2E_TOKENIZER_PATH
//!
//! Run with: cargo test --package cognee-cognify --test e2e_lifecycle_loop
