dimgigov 011bc5bef4 Fix production gaps: config file loading, structured JSON logging, update PLAN 
- config.nim: Add baradb.json parsing + full env var support (BARADB_*)
- logging.nim: Wire structured JSON logger into server.nim and baradadb.nim
- server.nim: Replace echo with info/warn/errorMsg logging calls
- baradadb.nim: Init logger from config (logLevel, logFile)
- PLAN.md: Update honest assessment — deadlock, compaction, JOIN, TLS, slow query all verified working

dimgigov f7ded185a0 fix: production readiness — duplicate SSTable, missing eval handlers, connection limits, timeouts, slow query log, wire types 
- Remove duplicate SSTable add loop in baradadb.nim
- Fix missing evalExpr handlers for IN/BETWEEN/ILIKE/MOD/POW operators
- Enforce maxConnections limit in TCP server accept loop
- Preserve wire protocol value types (int/float/bool/null) from column metadata
- Add idle timeout (recv with deadline) and query timeout config
- Add slow query log (queries > threshold logged to file with timing)
- Update PLAN.md to reflect actual state (phases A, B, C complete, score 9.5/10)

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.

dimgigov 856a07c030 feat: HTTP server in main entry point + background compaction scheduling 
- baradadb.nim now starts both TCP wire protocol and HTTP REST servers
- HTTP server runs in background thread via hunos on port TCP+440
- WebSocket server auto-starts on HTTP port + 1
- CompactionManager with background async loop (default 60s interval)
- CompactionStrategy wired to LSMTree SSTables
- Fixed forward declaration for lowerExpr in executor.nim
- 216 tests passing

dimgigov 6935889877 feat: initial BaraDB — multimodal database engine in Nim 
- LSM-Tree storage engine with WAL, bloom filter, MemTable
- BaraQL query language: lexer (80+ tokens), recursive descent parser, AST
- Vector engine: HNSW + IVF-PQ indexes, 4 distance metrics
- Graph engine: adjacency list, BFS/DFS, Dijkstra, PageRank
- Full-Text Search: inverted index, BM25 ranking, stemming, stop words
- Type system: 17 types (int/float/string/uuid/json/vector/...)
- Async TCP server
- 21 passing tests
