Result (as stated)

Final scores (highest → lowest): Converge — 13/13; Replit — 5/13; v0 — 3/13; Bolt — 2/13; Lovable — 0/13.

Places we recorded: #1 Converge (13/13) · #2 Replit (5/13) · #3 v0 (3/13) · #4 Bolt (2/13) · #5 Lovable (0/13)

Conflict of interest: Strong — Converge is the author's product and finished 13/13 while competitors scored ≤5. Treat as vendor-adjacent.

Useful checklist detail; tallies still counted but COI flagged on the site.
