No Wrong Door
A routing philosophy borrowed from the U.S. Administration for Community Living’s service design principle, applied to Guildhall.
The original
The No Wrong Door system is a federal initiative ensuring that people seeking long-term services and support can access what they need regardless of which agency or access point they contact first. 56 states and territories, 1,322 access points, all connected. The principle: it doesn’t matter which door you walk through — you get routed to the right service.
Applied to Guildhall
Guildhall serves multiple workflows: Quorum for deliberative evaluation, Lugh for adaptive learning, future workflows for building, research, and other tasks. The user shouldn’t need to know which workflow handles their request.
Entry point examples
| User says | Routed to | Why |
|---|---|---|
| ”I have an idea for a product” | Quorum | Deliberative evaluation needed |
| ”I want to learn about design patterns” | Lugh | Adaptive learning pipeline |
| ”Evaluate whether Lugh’s gate threshold is too strict” | Quorum (reviewing Lugh) | Meta-evaluation of another workflow |
| ”What did the Gamer flag about marketplace ideas?” | Memory search | Cross-run recall across Quorum history |
| ”Build me an MVP spec for this” | Quorum → builder workflow | Quorum validates, builder executes |
Ambiguity handling
When the input could belong to multiple workflows, the router asks — it doesn’t guess. “I don’t know which door you want” is better than opening the wrong one.
When the input clearly belongs to one workflow but the user doesn’t know that workflow exists, the router opens the right door silently. The user never needs to learn the word “Quorum” to get a product evaluation.
Connection to the building metaphor
In The Building, doors are entry points. The GUILD.md (Layer 1) is the lobby directory. The router reads the input, checks the directory, and walks the user to the right wing. The user experiences one building with one entrance. The internal architecture — wings, rooms, seats, stages — is invisible unless they want to see it.
