The natural-language interface used across the team's tools — standalone, not a MUSE component. Used throughout GLYPH today, and headed toward most of the other tools.
CALLIOPE is how natural language turns into action inside the team's tools — commands, queries, and shorthand phrased the way a person would actually say them, resolved into the specific operation a tool needs to run. It's the same interface whether you're driving GLYPH's terminal, its command palette, or (eventually) other tools entirely.
CALLIOPE isn't a MUSE component — it doesn't simulate anything and has nothing to do with entity behavior. It's infrastructure for using the tools, which happens to include the tools that build MUSE. It graduated to Laboratories the same way any Workshop build can: the whole team relies on it now, not just its original author. (Internally it's still called BABEL in the codebase — CALLIOPE is the name used in conversation and UI.)
Honest status: this is a team tool, not a shipping product — no public screenshots or feature tour yet. This page will grow as CALLIOPE's own story is ready to tell.
