Example output

🔥🔥🔥 CODE REVIEW: "Initiative Bonus"

Your tests are thorough. Like, suspiciously thorough. 156 lines for a POST endpoint? You're basically writing a dissertation on HTTP status codes.

That selectChain helper is magical incantation — nobody knows why .select() returns itself. Add a comment explaining the Supabase API you're mimicking.

849 lines added, 7 removed. That's 121:1 ratio. For a "bonus feature," this sprawls.

Severity: 🔥🔥🔥 (Ship after fixing migration description, simplifying mocks)
