# Book II — Human Stewardship Guidelines (Overview)

Book II organizes the ratified Human Stewardship Guidelines into the
canonical Library manuscript. The Constitution (Book I) declares what
PosterityOS protects; Book II describes how Stewards practice that
responsibility.

## Purpose

- Present the HSG as a readable, navigable manuscript.
- Preserve the ratified authority of the platform's `hsg-volume-*`
  registries — the manuscript never overrides source data.
- Declare the canonical fifteen-volume structure so future work has a
  stable frame.

## Fifteen-volume structure

| # | Volume | State |
|---|--------|-------|
| I | Foundations | ratified (source: `hsg-volume-1`) |
| II | The Steward | ratified (source: `hsg-volume-2`) |
| III | Hospitality | ratified (source: `hsg-volume-3`) |
| IV | Human Attention | ratified (source: `hsg-volume-4`) |
| V | Human Understanding | ratified (source: `hsg-volume-5`) |
| VI | Human Conversation | scaffolded |
| VII | Human Memory | scaffolded |
| VIII | Human Relationships | scaffolded |
| IX | Human AI | scaffolded |
| X | Human Craftsmanship | scaffolded |
| XI | Human Time | scaffolded |
| XII | Human Growth | scaffolded |
| XIII | Human Organizations | scaffolded |
| XIV | Human Systems | scaffolded |
| XV | The Steward's Oath | scaffolded |

Scaffolded volumes carry identity, purpose, and foundational belief.
Principles, doctrines, patterns, and practices are populated only
through the Steward Contribution Protocol and a subsequent Edition.

## Invariants

- Book II cannot redefine the Constitution.
- Volumes remain ordered I..XV.
- Ratified volumes are immutable relative to their prior snapshot.
- AI is never listed as a ratifier or history author.
- Products cannot weaken volume boundaries.
- History remains append-only.
- Relationships preserve lineage back to the Constitution.
