Current limitations

The examples document behavior that exists in the current pipeline. The main limitations are:

  • The REPL executes the supported queries but prints flat tab-separated rows. Nested select shapes are present in the resolved IR and SQLite plan, but runtime nested result reconstruction is not implemented.
  • gelite repl --schema compiles and renders queries but cannot execute them. Use --debug to inspect SQL and bind values.
  • gelite repl --database executes select, insert, update, and delete. It does not provide a JSON result format.
  • Initial schema application expects a new database. Migration diffing and migration history are not implemented.
  • Inserts and updates accept scalar literals, single-link ID strings, and single-link selects narrowed by an implicit id or declared unique scalar field. Nested inserts, general subqueries, and multi-link mutations are not implemented.
  • Composite unique constraints are not available in the current schema syntax. Association objects such as OrderItem and PlaylistTrack rely on the application to reject duplicate link pairs when needed.
  • Update and delete filters are optional. The CLI does not ask for confirmation before an unfiltered mutation.
  • Transaction commands work only in an interactive database-backed REPL. Enter start transaction, commit, or rollback as separate inputs.

The authoritative syntax and semantic contracts remain in spec/schema.md and spec/query.md.
