//! `StorageAdapter` trait and the query/update AST adapters lower.
//!
//! **The trait must be shaped by two consumers, not one.** Building against Mongo alone bakes
//! Mongo-isms (BSON semantics, `$` operators, implicit schema) into the interface, and the
//! Postgres port then fights it, which is roughly what happened upstream and produced the 55
//! catalogued divergences. The rule: if a method can only be implemented sensibly for one
//! backend, the trait is wrong.
//!
//! 0.2.0 added the query tree (`$or`/`$and`/`$nor`), the update op AST, atomic field reservation,
//! join-table primitives and schema mutation. Aggregation, distinct and transactions are still
//! absent, and a batch that asks for a transaction is refused rather than silently run without
//! one.
