Walkthrough

A complete in-memory graph database driver ("sonic") is introduced, featuring mutex-guarded node/relationship maps, adjacency indexes for O(1) neighbor lookup, Cypher query execution with AST walking, multi-clause filtering and evaluation, BFS shortest path computation, batch upsert operations, and comprehensive test coverage.

Changes

Cohort / File(s)	Summary
Driver Registration & Core drivers/sonic/sonic.go, drivers/sonic/transaction.go, drivers/sonic/batch.go	Driver registration via init(), in-memory Database type with transaction and batch entrypoints, node/relationship CRUD, ID allocation via atomic counters, adjacency index maintenance, identity-based upsert with property merging.
Query Engine & Execution drivers/sonic/queries.go, drivers/sonic/cypher.go, drivers/sonic/execute.go	nodeQuery and relQuery types with filtering, CRUD, and result streaming; Cypher execution via AST walker handling MATCH/OPTIONAL MATCH/WHERE/WITH/RETURN; ORDER BY/LIMIT/SKIP/DISTINCT support; pattern expansion with variable-length paths via BFS; special allShortestPaths handling.
Expression Evaluation & Pathfinding drivers/sonic/eval.go, drivers/sonic/pathfinding.go	Direct and binding-aware expression evaluation supporting comparisons, kind matching, property resolution, functions (id, type, toLower, etc.), and type coercion; constraint extraction from Cypher criteria; BFS-based shortest path computation with constraint filtering and multi-path reconstruction.
Documentation & Tests drivers/sonic/README.md, drivers/sonic/sonic_test.go, drivers/sonic/integration_test.go	Architecture and capability documentation; comprehensive unit tests covering CRUD, property filtering, shortest paths, Cypher correctness, variable-length patterns, concurrent operations; integration tests validating ops package behaviors and batch mutations.

Poem

🐰 In memory's garden, I planted seeds bright,
A sonic driver that runs super fast and light—
With paths that skip through graphs in a bound,
All MATCH'd and RETURN'd without touching the ground!
From WHERE clauses whisper to nodes that align,
This in-memory magic makes databases shine! ✨
