M2: RETRIEVE query pipeline with 5-stage execution (candidate → filter → score → diversify → limit),
usearch HNSW vector index, bitmap/range/universe filters, ranking profiles with signal scoring,
MMR diversity enforcement, and m2_uat integration tests.
M3: Entity system with typed metadata, relationship graph (follows/blocks/interactions),
creator entities, session tracking, and m3_uat integration tests.
M4: Advanced ranking with builtin functions (freshness, trending, controversy, wilson),
ranking executor with explain mode, query executor integration, benchmarks for
query/ranking/vector/filters/diversity, and m4_uat integration tests.
Includes: 9 new blog posts, marketing site updates, updated roadmap, and updated vision doc.

//! Milestone 2 User Acceptance Test.
|
|
//!
|
|
//! Exercises the complete M2 scenario end-to-end:
|
|
//!
|
|
//! 1. Open a persistent database with a full signal schema.
|
|
//! 2. Write 1K items with category, format, creator, and `created_at` metadata.
|
|
//! 3. Write 1K signal events spread across view, like, share, skip, completion.
|
|
//! 4. Execute 6 profile queries verifying ordering and correctness.
|
|
//! 5. Write a signal burst and verify rank change.
|
|
//! 6. Shutdown and reopen to verify crash recovery.
|
|
//!
|
|
//! For 10K-scale validation, run the ignored `milestone_2_uat_10k` test.
