orion-search/core

The framework-free core of Orion: the neutral query and index-schema ASTs, the engine adapter contracts (SearchAdapter, SchemaAdapter, WriteAdapter) and the Capability model, the index lifecycle (planner, versioned indices and alias swap, zero-downtime reindex by outbox replay, signed receipts), the tenancy seam, the search: manifest, the health checks and a dev InMemory engine.

Entry point: Orion::create(new Orion\Wiring\Config(...)). Every port in Config has a working default; pass your own to replace it. Nothing here imports a framework, an ORM or an engine client.

The design is docs/spec/ in the monorepo (github.com/univeros/orion).
