Navi

Navi is a Personnal Assistant

It's a public architectural surface of a production system whose business core stays private.

This repository is not a sample app or a learning scaffold. It exists so the structural layer—how workflows are composed and executed—can be inspected, versioned, and evolved in the open while rules, scoring, integrations, and real workflow definitions remain on the private side.

The shape of the system:

• Structured workflows — execution proceeds as an ordered set of steps with an explicit Context and recorded Events.
• Composable execution — each unit of work is an Action; the runner wires them without embedding domain meaning in the public names.
• Maintainable boundaries — Domain, Application, and Infrastructure stay separated so the private codebase can grow without collapsing this contract.

What you will not find here

Business use cases, decision logic, matching or scoring, domain-specific naming beyond generic execution terms, connectors, or production workflow graphs. Those live with the private system.

Execution flow

Input: Context. The WorkflowRunner invokes each Action in order; each action returns ActionResult (updated context and optional Events). Output: WorkflowResult wrapping the final ExecutionState.

Run

composer install
composer test
php bin/console navi:workflow:run

The console command runs the same structural path as the test: two merge actions and JSON output of the resulting state. It is a smoke check for wiring, not a stand-in for real workflows.
