Hey team,

Attached the revised GTM deck for Q2. Key changes from last week:

• Moved enterprise launch to April 15 (from May 1)
• Added Slack integration as tier-1 launch feature
• DevRel budget increased to $45K
• New section on competitor positioning vs. Superhuman

Need sign-off by Thursday so we can brief sales Friday.

Just merged the auth refactor. Can someone review the migration script before we deploy to prod?

On it. The rate_limiter config also needs updating for the new endpoints — I'll bundle that in my review.
