Document pagination sort bug on GET /member#1
Merged
Conversation
GET /member with sort=-updatedAt produces duplicate records across pages, causing ~33% of members to be silently missed. Adjacent pages share 41/100 members. Default sort (-lastOnline) is stable with only ~1.3% duplicates. Adds reproduction steps, test results table, impact analysis, and workaround to the gotchas doc.
