The repository is being developed incrementally as a structured series of articles, diagrams, architecture decisions, and practical examples.
Start with the [series overview](docs/00-series-overview.md). The current practical material includes [PlantUML diagrams](diagrams/readme.md) and an [A/B trial boot simulation](examples/simulations/ab-trial-boot/readme.md) with startup and recovery failure scenarios.

The current practical material includes [PlantUML diagrams](diagrams/readme.md), an [A/B trial boot simulation](examples/simulations/ab-trial-boot/readme.md), and an [interrupted installation model](examples/simulations/interrupted-installation/readme.md). [Chapter 06: Atomic Updates](docs/06-atomic-updates.md) connects preparation, activation, and recovery after interruption.
See the [changelog](CHANGELOG.md) for dated updates to the chapters, architecture decisions, diagrams, and simulations, with links to the material and related history.
