v0.24.0

Performance

• O(1) parameter deduplication: replaced linear Vec scan with FxHashMap for ~20% faster stub ingestion on large vendor sets. Deduplication now runs in parallel within rayon Pass 1 instead of serializing the collector.
• RwLock-based atomic counter writes for Salsa db updates, reducing lock contention during batch analysis and improving 12-thread scaling.
• file_references forward index added to MirDb: dependency_graph() cost reduced from O(S×R) to O(E) (files × edges), eliminating full-table scans during incremental re-analysis.
• In-memory always-on reverse dependency map (structural_dependents_of) for O(D) BFS over structural dependencies (imports, class hierarchy, type hints) without requiring disk cache.

Fixed

• Reference location recording now complete at all five previously-missing call sites: instanceof, catch, ::class, ::CONST, and type-hint declarations. Files referencing a class only via these constructs are now correctly visible to the incremental dependency graph and analyze_dependents_of().
