+# User Story
+
+As a registered player, I want to manage my profile and linked Minecraft accounts, so that my whitelist identity remains current.
+
+# Acceptance Criteria
+
+- [x] Given an authenticated user, then only their own profile, accounts, and IP observations are visible and mutable.
+- [x] The user can update their preferred name.
+- [x] The user can add Mojang-verified or explicitly confirmed accounts from an allowed network.
+- [x] The user can soft-remove an active account.
+- [x] The user can choose exactly one active primary account.
+- [x] Removing a primary account promotes another active account when one exists.
+- [x] Name and primary changes show the expected Discord nickname and require confirmation.
+- [x] The dashboard shows recent portal and game IP observations with classification and available location.
+- [x] The user can revoke the current session by signing out.
+
+# Implementation
+
+- [`apps/web/src/app/account/page.tsx`](../apps/web/src/app/account/page.tsx)
+- [`apps/web/src/app/account/actions.ts`](../apps/web/src/app/account/actions.ts)
+- [`apps/web/src/app/auth/actions.ts`](../apps/web/src/app/auth/actions.ts)
+
+# Validation
+
+Server actions verify the current session and constrain every account lookup by the authenticated user ID.
