Concept Registry — Tuig

Prefix: CONCEPT:TUI-* Version: 2.3.5 Bridge: CONCEPT:AU-ECO.messaging.native-backend-abstraction (Unified Toolkit Ingestion)

---

Runtime ownership

tuig is a frontend client, not an MCP or A2A server. It consumes Arbora task and operation contracts. Backend orchestration and knowledge decisions remain upstream. Historical Python concept descriptions remain in git history.

Native terms

tuig: the sole native Rust/Ratatui command.

Arbora: the served task and operations authority.

A2A: the currently implemented task transport.

ACP: Agent Client Protocol; the experimental local headless path uses it for one text turn through an owned backend child. Installed-backend and full protocol acceptance remain open.

Headless: native unary observation without a terminal renderer.

See the ecosystem glossary for shared terms. The shared Pages theme owns that generated glossary; keep native terms on this page.
