From bf590888f014931370a23023ad0e427e71110752 Mon Sep 17 00:00:00 2001 From: Hyo Date: Sat, 18 Apr 2026 04:08:40 +0900 Subject: [PATCH 1/7] feat(server): add phone auth, group roles, and mentions Add phone number verification with OTP: - POST /v1/auth/phone/send-code - send OTP - POST /v1/auth/phone/verify - verify OTP - Rate limiting per phone number and IP Add group member roles: - OWNER, ADMIN, MEMBER role system - Track who added each member - Support up to 1000 members per group Add mentions tracking: - Store @mentions for efficient "messages mentioning me" queries - Indexed by mentioned
