Aikeedo is a PHP application assembled from small PSR components rather than a full-stack framework. Reading this section pays off when you’re writing a non-trivial plugin, tracing a bug, or deciding how to customize something safely.
This page applies to Aikeedo 5.x. Class names, paths and signatures match the 5.0 source code.

Design principles

src/ is split by domain rather than by technical layer: Ai, Billing, User, Workspace, Chatbot and so on. Each owns its entities, repositories, commands and events.
Behavior is expressed as a command plus a handler, dispatched through a bus. Reads use the same mechanism, so ListPlansCommand and CreateOrderCommand look alike from the outside.
Entities take value objects, not scalars. Validation lives in the value object’s constructor, so an invalid Email or Price can’t exist.
Payment gateways, tax engines, storage adapters, vector stores, AI services and tools are all looked up from registries a plugin can add to.
Handlers change entities; the application flushes once, after the response is sent.
