+# Player List + Kick + Waitlist Promotion Implementation Plan
+
+> **For Hermes:** Use subagent-driven-development skill to implement this plan task-by-task.
+
+**Goal:** Add a player list (with names) to the Web UI session views, allow GM to kick a specific player, and auto-promote the next waitlisted player.
+
+**Architecture:** Extend `ISessionStore` with participant queries and a remove method. Update `GroupDetails.razor` to show expandable participant lists. Reuse existing `PromoteWaitlistedPlayerAsync` logic after removal.
+
+**Tech Stack:** C# 14, Blazor SSR, Dapper, PostgreSQL
+
+---
+
+## Task 1: Add domain model for WebParticipant
+
+**Objective:** Create a DTO to represent a session participant in the web layer.
+
+**Files:**
+- Modify: `src/GmRelay.Web/Services/SessionService.cs`
+
+**Step 1: Add record**
+
+```csharp
+public sealed record WebParticipant(
+    Guid Id,
+    long TelegramId,
+    string DisplayName,
+    string? TelegramUsername,
+    string RsvpStatus,
+    string RegistrationStatus,
+    bool IsGm,
+    DateTime? RespondedAt);
+```
+
+**Step 2: Commit**
+
+```bash
+git add src/GmRelay.Web/Services/SessionService.cs
+git commit -m "feat: add WebParticipant record"
+```

+
+## Task 2: Add GetSessionParticipantsAsync to ISessionStore
+
+**Objective:** Retrieve all participants for a session with full player info.
+
+**Files:**
+- Modify: `src/GmRelay.Web/Services/ISessionStore.cs`
+- Modify: `src/GmRelay.Web/Services/SessionService.cs`

+                 sp.created_at
+        """,
+        new { SessionId = sessionId })).ToList();
+}
+```
+
+**Step 3: Add authorized wrapper**
+
+In `AuthorizedSessionService.cs`, add:
+```csharp
