# Module Management: Design for No Human

## Philosophy
If a system requires a hero to keep it running, it is a broken system. The goal is to make the "normal" path safe and automatic.

## What "no human" means
- Self-healing over manual repair
- Automation over tribal knowledge
- Clear contracts between modules
- Predictable failure modes

## Practical patterns
- Standard interfaces: versioned APIs, clear schemas, and strict backward compatibility.
- Idempotent operations: retries are safe by default.
- Declarative configuration: infrastructure and policies as code.
- Health checks and SLOs: the system can tell you when it is broken.
- Automated rollbacks: recover quickly without manual intervention.

## Governance
- Dependency mapping: know what breaks what.
- Change budgets: limit risk per deploy.
- Kill switches: safe off ramps for broken features.

## Documentation
- Docs are part of the system, not a separate task.
- Every module has an owner, a runbook, and a dashboard.

## Outcomes
This reduces toil, shortens recovery time, and makes scaling possible without proportional headcount growth.
