FunctionaL City begins as a planted flag—a declaration of intent to build something organic, inspectable, and legacy-worthy. We design not by accident, but by ordinance. Inspired by workflows from city government and civil engineering, our architecture is deliberate: parcel maps become modular districts, welcome ordinances guide newcomers, and domain models codify the foundational laws of our infrastructure.
Here, functional programming is not just a paradigm—it’s the city’s culture. Every morphism is a civic act, every module a subdivision with remix rights. We legislate clarity, steward workflows, and document every ordinance so others may inherit, inspect, and evolve. This is not just code; this is a city.
Our infrastructure is built on function — not fashion. The foundation of FunctionaL City is built on narrative domain models and foundational logic. We legislate in F#, not ceremony.
Ordinance 1.1: Functional Purity and Civic Isolation
Article I — Sovereign Ordinances
Every function shall operate as a sovereign parcel:
- Pure in logic — free from external dependencies or mutable state.
- Immutable in data — treating every input as sacred and every output as declarative signage.
- Side effects — being civic disruptions (I/O, mutation, randomness), must be zoned to the program’s perimeter—clearly marked as border crossings or public interfaces.
Article II — Rationale
This ordinance ensures:
- Inspectable infrastructure — each parcel is remixable and auditable.
- Traversal clarity — new citizens (developers) navigate without hidden traps or mutable potholes.
- Symbolic overlays — validator maps and truss audits can reason without runtime chaos.
- Continuity with Principle IV — pure functions, when documented, become civic artifacts in the archive.
Article III — Implementation Acts
- Use pure functions as the default ordinance type.
- Encapsulate side effects in effectful districts (e.g., monads, ports, adapters).
- Transform data, never mutate it—each transformation is a new civic fixture.
The foundation of our jurisprudence is mathematical purity. We legislate with exact arithmetic and symbolic reasoning, never with approximation disguised as truth. Every calculation is a civic record — auditable, narratable, and legacy-worthy.
Ordinance 2.1: Mathematical Purity and Auditability
Article I — Statutes of Exactness
Every derivation shall be:
- Symbolic in form — preserving exactness, not approximation.
- Transparent in reasoning — each step narratable and inspectable.
- Immutable in record — calculations preserved as civic artifacts.
Article II — Rationale
This ordinance ensures:
- Audit trails — every calculation is legacy-worthy and reproducible.
- Symbolic clarity — derivations are not hidden, but constitutional.
- Domain integrity — F# types and functions enforce lawful boundaries.
- Continuity with Principle I — pure functions are the lawful vessels through which symbolic reasoning flows.
Article III — Implementation Acts
- Prefer rational and symbolic arithmetic over floating approximations.
- Encode domain rules in F# types as statutes.
- Preserve derivations in civic records (logs, proofs, or overlays).
Each district is sovereign, remixable, and inspectable. No citizen is bound by opaque dependencies. Migration is lawful, and remix rights are protected.
Ordinance 3.1: District Sovereignty
Article I — Modular Boundaries
Every module shall be:
- Sovereign — encapsulating its own statutes and ordinances.
- Remixable — designed for lawful reuse and adaptation.
- Inspectable — free from opaque or hidden dependencies.
Article II — Rationale
This ordinance ensures:
- Lawful migration — districts can evolve without coercion.
- Protected remix rights — citizens inherit freedom to adapt.
- Sustainable growth — modularity prevents urban sprawl.
- Alignment with Principle II — symbolic reasoning ensures districts remain lawful in their boundaries.
Article III — Implementation Acts
- Design modules with clear interfaces and lawful contracts.
- Avoid tight coupling; enforce boundaries through types and signatures.
- Document migration paths as civic ordinances.
Every .md is a civic artifact — a record of law and lineage. Every blog post is a parcel map — guiding traversal through the city’s districts. We preserve clarity, not ceremony.
Ordinance 4.1: Documentation as Civic Record
Article I — Artifacts of Law
Every document shall be:
- Immutable in record — preserved as part of the civic archive.
- Narratable in form — written for inheritance and inspection.
- Mapped to districts — guiding traversal through FunctionaL City.
Article II — Rationale
This ordinance ensures:
- Heritage — documentation is not a hurdle, but a legacy.
- Clarity — records are preserved without ceremony or obfuscation.
- Continuity — future citizens inherit a narratable infrastructure.
- Alignment with Principle III — parcel maps document modular districts, ensuring sovereignty remains navigable.
Article III — Implementation Acts
- Treat
.mdfiles as civic artifacts, versioned in the archive.- Publish blog posts as parcel maps, guiding traversal and remix.
- Write for clarity and inheritance, not for ceremony.
The statutes of FunctionaL City are not static; they evolve. Our vision is to legislate a future where civic metaphors, symbolic reasoning, modular sovereignty, and narratable records interlock as a living constitution.
Ordinance 5.1: Future Statutes
Article I — Continuity of Law
Future ordinances shall ensure:
- Civic metaphors guide technical architecture.
- Symbolic math overlays inform engineering decisions.
- Documentation is heritage, not hurdle.
- Interlocking principles — purity, law, modularity, and legacy — remain constitutional statutes.
Article II — Rationale
This ordinance ensures:
- Sustainability — FunctionaL City adapts without losing its civic grammar.
- Legacy — future citizens inherit a narratable infrastructure.
- Integrity — principles remain lawful, remixable, and inspectable.
Article III — Implementation Acts
- Draft future ordinances as extensions of existing statutes.
- Cross-link principles to preserve interdependence.
- Ratify amendments as civic artifacts, versioned in the archive.
FunctionaL City is open-source by design and by ethos. Every ordinance is inspectable. Every district is forkable. Every citizen is a steward.
