7//! Property graphs and their posting representation.
8//!
9//! Defines `GraphStore` (trait + in-memory implementation), the
10//! `GraphPostingList` extension of [`uqa_core::PostingList`], and the
11//! lossless `Phi` codec for carrying graph metadata through ordinary posting
12//! storage. Graph-result merges expose their subgraph collision policy
13//! separately from ordinary posting payload merges.
