### New URL structure
| Old URL | New URL |
|---------|----------|

`/docs/ai-coder/agent-boundaries` |
| `/docs/ai-coder/boundary/nsjail` |
`/docs/ai-coder/agent-boundaries/nsjail` |
| `/docs/ai-coder/boundary/landjail` |
`/docs/ai-coder/agent-boundaries/landjail` |

### Follow-up required
Redirects need to be added to `coder/coder.com` for the old URLs:

(this one is currently 404'ing from Google search results)
- `/docs/ai-coder/boundary/:path*` →
`/docs/ai-coder/agent-boundaries/:path*`
