Dynamic Workflow Engine

Projects

Each project is a tenant with its own workflows, forms, rules and connectors. The same engine runs every project — only the JSON definitions differ.

Architecture

Multi-tenant layer

Project resolved per request (URL /p/[projectId]) — scopes every query by projectId.

1 · Admin designer UI

Workflow canvas (React Flow), form builder, rule / decision builder → versioned JSON.

2 · Definition store

workflow_definitions, form_definitions, rule_sets, connectors — draft + published versions.

3 · Workflow engine

advanceCase() → step handler registry (assignment, decision, automation, integration, parallel/join, subprocess) + SLA watcher.

4 · Case instance store

case_instances, assignments, case_history, notifications.

5 · Touchpoints

Task inbox, notifications, external callbacks (webhooks).
