Authority & Isolation Thinking

Overview

Ved enforces strict boundaries between system components through:

  • domain isolation
  • explicit authority

The Problem

In traditional systems:

  • components access shared state
  • responsibilities overlap
  • side effects are implicit

This leads to:

  • unpredictable behavior
  • tight coupling
  • security risks

Domain Isolation

A domain is:

a self-contained unit of state and behavior

Properties:

  • owns its state
  • cannot directly mutate other domains
  • communicates via messages

Authority Model

Each domain has:

  • a defined scope of control
  • explicit permissions

Authority determines:

  • what state can be modified
  • what effects can be emitted

Communication Model

All interaction occurs through:

message → mailbox → transition

No:

  • shared memory
  • implicit references

Benefits

Modularity

Domains are:

  • independent
  • composable

Safety

Isolation prevents:

  • unintended mutations
  • cascading failures

Observability

Message flow defines:

  • system behavior
  • causal relationships

Example

Bad (shared state):

global_count += 1

Ved:

domain Counter { state { count: int }

transition increment: count += 1 }

Authority Boundaries

Domains cannot:

  • mutate external state directly
  • bypass messaging

This ensures:

structural correctness of system interactions


Summary

Ved treats system design as:

a set of isolated, interacting authorities

This enforces:

  • discipline
  • safety
  • clarity
