|
|
-- Date: 2026-03-04
|
|
-- Issue: #44
|
|
-- Purpose: Support the scouting feature where players can scout cards
|
|
-- from other teams' opened packs within a 30-minute window.
|
|
--
|
|
-- Run on dev first, verify with:
|
|
-- SELECT count(*) FROM scout_opportunity;
|
|
-- SELECT count(*) FROM scout_claim;
|
|
--
|
|
-- Rollback: See DROP statements at bottom of file
