Polish: Claim + DNS-verify trunk.io for the Trunk publisher on VS Marketplace

Current state

The Trunk publisher on the VS Code Marketplace has the verified-publisher badge (✓) already, but no publisher domain is claimed.

Inspected via the marketplace API on 2026-06-30:

Publisher:        Trunk
Extension:        Trunk.io (Trunk Code Quality)
Flags:            verified              ← publisher account verified
Domain:           (empty)               ← no domain claim
DomainVerified:   False                 ← N/A without a claim
Installs:         214,623

Why this is a stronger ask than for solo maintainers

Trunk is a commercial company (trunk.io), not an individual maintainer. The trust-signal argument is stronger here than for solo OSS authors:

• Commercial company with an obvious domain (trunk.io)
• The extension does AI-driven code analysis and uploads diffs to Trunk's hosted service
• 214K+ installs

For a commercial publisher with cloud sync, domain verification is a standard expectation, not just optional polish.

How to complete

1. Sign in to https://marketplace.visualstudio.com/manage/publishers/Trunk
2. Edit publisher profile → set Domain to https://trunk.io
3. Domain verification → Microsoft provides a one-time DNS TXT record
4. Add the TXT to trunk.io DNS (TXT can be removed once verified)
5. Click "Verify"

5-minute task on the maintainer side.

Why I'm filing here

Trunk's VS Code extension doesn't have a public GitHub Issues tracker (the extension source isn't open-source on GitHub). Filing this on trunk-io/plugins as the closest visible issue tracker for the Trunk team. If there's a better channel, please redirect — or feel free to close as out-of-scope here and handle internally.

Thanks for Trunk Code Quality — the "one extension instead of 30" pitch is genuinely useful.
