dimgigov 96dfaaecb1 feat(sql): Advanced SQL — LATERAL, GROUP BY/HAVING, FILTER, aggregates, PIVOT, SQL/PGQ 
- 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

dimgigov eaa5760fd4 feat: JSON/JSONB validation, multi-column indexes, CTE execution, wire protocol column types 
- Add fkJson to wire protocol with serialization/deserialization
- Validate JSON/JSONB on INSERT/UPDATE via std/json
- Send real column type metadata in wire protocol responses
- Update all 4 clients (Nim, Python, JS, Rust) for JSON and columnTypes
- Implement multi-column index parser (CREATE INDEX idx ON t(a, b))
- Add ciColumns to AST nkCreateIndex
- Build composite index keys as table.col1.col2 with val1|val2
- Support multi-column exact match in SELECT for AND chains
- Implement non-recursive CTE execution via ctx.cteTables materialization
- Add tkRecursive token and parse WITH RECURSIVE
- Fix test isolation: use temp dirs for JOIN, migration, and RLS tests
- All tests passing (0 failures)

dimgigov f9f77b3a18 feat: production blockers — JOINs, deadlock detection, TLS, parameterized queries 
- JOIN execution: INNER/LEFT/RIGHT/FULL/CROSS with column disambiguation
- Deadlock detection: wait-for graph wired into TxnManager.write()
- TLS/SSL: OpenSSL via std/net for TCP wire protocol, auto self-signed certs
- Parameterized queries: ? placeholders with WireValue binding
- Wire protocol: mkQueryParams message support
- HTTP /query endpoint accepts JSON params array
- Nim client: query(sql, params) overload
- Tests: 262 passing (15 new)

All PLAN.md production blockers resolved.
