1
Design contract
State invariants, scope, and non-functional requirements.
Documentation-only system
System Design Lab
A compact architecture-to-CI/CD reference showing how design contracts become deterministic checks, reviewed releases, deployment gates, and operational-response runbooks.
Delivery lifecycle
Architecture workflow
The repository models a complete delivery loop at learning scale. Each stage has a clear contract and a bounded verification mechanism.
2
CI verification
Run deterministic checks before merge.
3
PR review
Review scope, risk, verification, and boundaries.
4
Release
Create a tagged checkpoint and artifact bundle.
5
Deploy
Promote reviewed documentation to GitHub Pages.
6
Respond
Use runbooks when verification or deployment fails.
System map
Reference architecture
The diagram shows the control flow from design intent to verified release and operational recovery.
Progression model
Maturity levels
Reviewed changes
Pull requests, verification, and branch-protection guidance.
Release automation
Manual checkpoint, tag workflow, and artifact bundle.
Deployment gates
GitHub Pages deployment with a clear rollback model.
Operational response
Runbooks, postmortem template, and simulated recovery.
Governance
Operating rule
Design defines the contract. CI verifies it. Deployment gates promote only reviewed states.
