# Restore Milestone (DEPRECATED)

**This command is no longer needed.**

<objective>
DEPRECATED: Archives are now permanent in history/. No restore operation needed.
</objective>

<process>

<step name="show_deprecation_and_exit">
Display deprecation notice using GSD branded banner format:

```
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
 GSD ► DEPRECATED
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

This command is no longer needed.

**Old workflow (deprecated):**
1. {{COMMAND_PREFIX}}complete-milestone    # Mark complete
2. {{COMMAND_PREFIX}}archive-milestone     # Move to milestones/
3. {{COMMAND_PREFIX}}restore-milestone     # Retrieve from milestones/ ← YOU ARE HERE

**New approach:**
Archives in `.planning/history/v{X.Y}/` are permanent and git-tracked.
There is no need to restore — simply reference files directly or use
git to view historical versions.

## Accessing Archived Milestones

**View milestone history:**
```bash
ls .planning/history/
```

**Read archived files:**
```bash
cat .planning/history/v1.0/ROADMAP.md
```

**View at specific git tag:**
```bash
git show v1.0:ROADMAP.md
```

**List all milestones:**
{{COMMAND_PREFIX}}list-milestones

───────────────────────────────────────────────────────────────

## Why No Restore?

The new workflow archives to permanent history/ with mirrored directory
structure. Files are git-tracked and always accessible. Restoring would
conflict with the current active milestone.

If you need to reference old planning artifacts, use bash commands to
read them directly from history/ or use git commands to view historical
commits.

Exit immediately without executing any operations.
