Overview

Ved is designed for systems that:

  • run continuously
  • evolve over time
  • maintain persistent state

Traditional Model Limitation

Most programs assume:

  • short execution
  • stateless behavior
  • restart safety

Control planes violate all three.

Long-Lived Systems

Examples:

  • infrastructure controllers
  • schedulers
  • orchestration engines

Characteristics:

  • persistent state
  • continuous execution
  • external interaction

Ved Approach

Ved treats systems as:

continuously evolving state machines

Persistent State

State is:

  • durable
  • versioned
  • recoverable

Execution Continuity

Execution does not "restart":

  • it resumes
  • it converges

Failure Handling

Failures are handled through:

  • replay
  • re-convergence

State Evolution

State must support:

  • schema evolution
  • incremental updates

Design Implications

Developers must think in terms of:

  • stability
  • convergence
  • long-term correctness

Summary

Ved is not for:

short-lived computation

It is for:

systems that must remain correct over time
