project_semantic.rs

1//! Many-to-many between historical projects and semantic-graph nodes.
2//!
3//! Replaces the old `semantic_node.project_id` column. A canonical (merged)
4//! semantic node may participate in many historical projects, so the
5//! provenance link lives in this side table instead of being scalar on the
6//! semantic row. Each row records "project P contributed (or shares) semantic
7//! S". The same `(project_id, semantic_node_id)` pair must not be inserted
8//! twice — the composite primary key enforces that.
9//!
10//! Note: `semantic_node_id` here may reference either a canonical node or a
11//! merged-away (raw) node. Consumers that need only canonical visibility
12//! should resolve through `semantic_merge`.
