Castalia · Platform
Executable marketing in the age of AI — audience and message worlds, immutable runs, evidence with provenance, reviewable plans, and lineage you can defend for compliance and audit.
In ancient Athens, the agora was the public square: debate, evidence, and decisions under scrutiny. This project applies that idea to software — a place where marketing work is not only creative but traceable, structured, and inspectable.
Agora is Castalia’s platform for that vision. It implements the architecture described for the Mag.AI-Marketing program: teaching and production share the same primitives, so what you learn matches what you ship.
The open repository holds schemas, examples, and validation today; services, SDKs, and integrations land here as they are built. The curriculum and degree framing live in Mag.AI-Marketing; this site is the technical home for the executable platform.
Core concepts map directly to artifacts and APIs — from world models through to audit-ready lineage.
Executable audience, message, and channel model (PTAH-shaped) — the context your runs execute against.
A controlled perturbation applied to a world — “what if” without losing the base model.
Immutable execution record: versions, seed, outputs — the unit of reproducibility.
Signals with provenance and explicit limits, validated against the Evidence schema.
Structured steps, assumptions, optional tool allowlists — reviewable before execution.
Trace from inputs → runs → decisions — the backbone for defense, compliance, and review.
