Cellular Mode v1.0.0 — User Guide

Official user guide for Cellular Mode v1.0.0, an open-source method and software architecture for bounded, resumable, auditable, and verifiable agent-assisted software engineering. The guide is written for people who want to use Cellular Mode v1.0.0 in a real project. It covers the recommended path for a new project, from Git initialization through Prompt Builder, contract approval, Bootstrap dry-run and installation, to the first verified cell; analysis-first adoption into existing projects without overwriting existing files; cells, their fields, states and lifecycle; opening, working, pausing, resuming and switching cells; the vault as persistent operational state, with an append-only log and rebuildable projections; cell completion and Article 8 final-state verification, including its claim boundary; Bootstrap installation profiles; the optional and experimental Cellular Adaptive module; the optional Observer dashboard and Universal Plugin Protocol (UPP); installation status, drift and uninstall; common problems; what Cellular Mode does not promise; a command quick reference; and a glossary. The commands and behaviors described correspond to the public v1.0.0 release of the tmulab/cellular-mode repository (software DOI: 10.5281/zenodo.23239314). If the guide and the software diverge, the versioned release and its documentation files are the operational source of truth.
