read
Opens a reader over handle at snapshot, pinning every sidecar it may consult.
Close it. On Windows a mapped file cannot be deleted, so a reader left open blocks reclamation of every segment it touched — which IndexLifecycleTest asserts in both directions.
Outside the stable core: this hands back an ordinal-space reader over sidecar bytes, and both the ordinals and the bytes are the format's rather than a contract's. Rabosh.query is the stable way to ask an index a question. See STABILITY.md.
