- LATERAL JOIN: correlated subquery strategy (scan + merge + filter/sort/limit)
- GROUP BY: SUM/AVG/MIN/MAX evaluation inside groups, HAVING filter
- FILTER (WHERE ...): conditional aggregates for COUNT/SUM/AVG
- ARRAY_AGG / STRING_AGG: multi-argument aggregate functions
- GROUPING SETS / ROLLUP / CUBE: powerset generation for multi-level aggregation
- PIVOT / UNPIVOT: row-to-column and column-to-row transformation
- SQL/PGQ Property Graph: GRAPH_TABLE MATCH parser + executor skeleton
- 330 tests passing, all 4 modalities (SQL/JSON/Vector/Graph) integrated

feat: schema inheritance, codegen, replication, mmap — 136 tests
...
Schema:
- Inheritance: multi-level, property merging, override, isSubtype
- Computed properties with expressions
- getSubtypes for polymorphic queries
Codegen:
- IR plan → storage operations compilation
- Predicate pushdown optimization (filter → point read)
- Cost estimation and EXPLAIN output
Replication:
- Sync replication (wait for all replicas)
- Async replication (fire and forget)
- Semi-sync (wait for N replicas)
- Replica state tracking and lag monitoring
Storage:
- Memory-mapped I/O for SSTable access
- Sequential/random access hints (madvise)
- Page-level read operations
