+* **Extend**: Add SoMC Portal branding, live Discord identity details, admin guild configuration visibility, and fail-closed group-based Minecraft admission.
+* **Refine**: Group repeated access networks, confirm linked Discord nickname changes before mutation, and add DMG Games sponsorship attribution.
+* **Extend**: Add shared Pino logging with credential redaction and actionable web and Discord runtime diagnostics.
+* **Fix**: Build magic-link redirects from the configured public portal URL instead of the reverse proxy's internal request origin.
+* **Verify**: Confirmed `v1.1.1` left all pre-existing `latest` digests unchanged while publishing versioned artifacts.
+* **Refine**: Removed mutable `latest` publication so all deployable artifacts use explicit semantic versions.
+* **Verify**: Confirmed the `v1.1.0` Discord bot image and matching web, migration, and Velocity artifacts.
 * **Extend**: Added a releasable Discord bot image and a dependency-free web health endpoint for Kubernetes deployment.
 * **Verify**: Confirmed the initial `v1.0.0` release, public Velocity JAR, and versioned and `latest` web and migration image manifests.
 * **Create**: Added Gitea CI and semantic-release pipelines for downloadable Velocity JARs and versioned web and migration images.

+# User Story
+
+As an administrator, I want to organize registered users into access groups, so that server admission can be enabled for selected communities while remaining off by default.
+
+# Acceptance Criteria
+
+- [x] Every registered user implicitly belongs to the protected `everyone` group.
+- [x] The `everyone` group is created with Minecraft access disabled.
+- [x] Administrators can create groups with access disabled by default.
+- [x] Administrators can add and remove users from non-default groups.
+- [x] Administrators can enable or disable Minecraft admission for each group.
+- [x] A registered player is admitted when any assigned group has access enabled.
+- [x] A registered player is denied when none of their groups has access enabled.
+- [x] Group creation, membership, and access-policy changes are audited.
+- [x] Users and administrators can inspect the user's effective group assignments.
