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.

## Regression: sequential wire-style INSERTs must not crash the process.

## Root cause was ORC cycle collector (markGray SIGSEGV); project uses --mm:arc.
