Application service
acorn-service exposes three transport-neutral operations over supplied content: Research Activity validation, readability checking, and deterministic repository processing. It also owns the typed JSON-RPC registry used by acorn-server.
cargo add acorn-service
Requests never name local files to open. Repository inputs carry lexical relative paths and content, and processing returns ordered reports and proposed changes without writing a working tree. Use acorn-server when these same operations need authenticated JSON-RPC or typed gRPC transport.
