Core storage: hash MemTable, WAL group commit, L0 compaction rebuild, reader-writer lock, and a global StorageGate so HTTP workers and TCP share the LSM safely under multi-thread access. Schema: durable CREATE/ALTER/DROP under _schema:tables:* with full LSM restore on open. Executor types/values/schema split into query/exec/. Wire protocol: switch default MM to ARC — ORC cycle collector segfaulted after ~20 async INSERTs. Fair multi-tier benchmarks (SQLite/HTTP/wire/PG) and honesty docs for mixed-tier comparisons.

Methodology
- Tier
embedded: in-process only (BaraDB LSM from nimble bench JSON; SQLite via Python sqlite3). - Tier
client_server: network SQL (BaraDB HTTP /query; BaraDB binary wire TCP; PostgreSQL via psycopg2). sql_insert_row: one INSERT statement per row (chatty).sql_insert_batch: multi-row INSERT with batch size 50 (same SQL style across systems).- PostgreSQL: synchronous_commit=on|off; SQLite: PRAGMA synchronous FULL|OFF.
- BaraDB WAL modes appear only if you ran benchmarks/bench_all.nim (WAL-* rows).
- Never claim 'Nx faster than Postgres' using embedded BaraDB numbers.
Do not compare numbers across tiers. Embedded storage is not the same workload as client-server SQL over the network.
