- Change sandbox ID prefix from sb- to cl- (capsule) throughout
- Fix proxy URL regex character class: base36 uses 0-9a-z, not just hex
- Add MMDS V2 config and metadata to VM boot flow so envd can read
WRENN_SANDBOX_ID and WRENN_TEMPLATE_ID from inside the guest
- Pass TemplateID through VMConfig into both fresh and snapshot boot paths
Add SafeName validator (allowlist regex) to reject directory traversal
in user-supplied template and snapshot names. Validated at both API
handlers (400 response) and sandbox manager (defense in depth).
Refactor CreateNetwork with rollback slice so partially created
resources (namespace, veth, routes, iptables rules) are cleaned up
on any error. Refactor RemoveNetwork to collect and return errors
instead of silently ignoring them.
