# Source Of Truth And Mirror Standard

Principles only. Runnable steps live in Capabilities — not here.

Apply rules (purpose, purge): [RepositoryMirrorStandard.md](RepositoryMirrorStandard.md).

## Authority Hierarchy

| Rank | Surface | Role |
| --- | --- | --- |
| 1 | Local Git repository | Source of truth — all normal edits |
| 2 | GitHub | Backup, history, collaboration |
| 3 | Google Drive (optional) | Review mirror target — **not connected to Git** |

## When No Local Clone Exists

For **Remote-only** or **GitHub-then-local** profiles:

- **GitHub** is the working collaboration surface.
- Cloud review mirrors are **never required**.
- When the user later clones, **local Git becomes authoritative**.

## Default: No Cloud Copy

Do not automatically copy files to Google Drive after local edits.

Cloud copy happens **only** when the owner explicitly requests mirror refresh
or review sync.

## Runnable Workflow Indexes

| Task | Start file |
| --- | --- |
| Windows repository mirror | `Capabilities/MirrorToWindows/WorkflowIndex.md` |
| Google Drive planner loop | `Capabilities/GoogleDriveLink/WorkflowIndex.md` |

First-time mirror setup writes paths to `Workspace/OwnerPreferences.md` § Connectors.

Mirror apply: `Capabilities/MirrorToWindows/MirrorWorkflow.md` (docs-only —
manual Robocopy or copy in this starter).

## Disposable Review Copies

When **Mirror purpose** is `review`, the target folder is a disposable read
copy. When purpose is `backup`, purge is off by default. GitHub holds version history.
