+# Plan: Commissioner Without a Team
+
+## Current State
+
+**At the database level**, commissioners and teams are already independent:
+- Commissioners are stored in the `commissioners` table (league-level, keyed by `leagueId` + `userId`)
+- Teams are stored in the `teams` table (season-level, keyed by `seasonId` + `ownerId`)
+- A commissioner does NOT need a team to access the league homepage or draft room — this already works
+
+**The actual problem** is that there's no way to *become* a commissioner without also getting a team:
+1. **League creation** (`app/routes/leagues/new.tsx:198-201`): The creator is always assigned the first team (`ownerId: i === 0 ? userId : null`)
+2. **No "Add Commissioner" UI**: There's no way for a league creator to add additional commissioners at all
+3. **Invite link flow** (`app/routes/i.$inviteCode.tsx`): Joining always assigns a team — there's no option to join as commissioner-only
+
+**Also**, the league creation flow has no opt-out for team ownership — the creator always gets Team 1.
+
+## Changes
+
+### 1. League creation: Add "Join as player" checkbox
+**File**: `app/routes/leagues/new.tsx`
+
+- Add a checkbox: "I want to play in this league" (checked by default)
+- When unchecked, skip assigning the creator to the first team (all teams get `ownerId: null`)
+- When checked, behavior stays the same (creator gets first team)
+
+### 2. Add Commissioner Management UI to League Settings
+**File**: `app/routes/leagues/$leagueId.settings.tsx`
+
+- Add a new "Commissioner Management" card section
+- Show current commissioners with a "Remove" button (cannot remove if they're the last commissioner)
+- Add an "Add Commissioner" form with a user search/select dropdown
+  - Only show users who are already members of the league (team owners) OR allow adding by searching all users
+  - Since only the site admin can currently assign users to teams, let's keep it simple: commissioners can add any registered user as a commissioner
+- Backend actions: `add-commissioner` and `remove-commissioner` intents
+
+### 3. Model changes
+**File**: `app/models/commissioner.ts`
+
+- Already has `createCommissioner`, `deleteCommissioner`, `removeCommissionerByLeagueAndUser` — these are sufficient
+- Add `countCommissionersByLeagueId` to prevent removing the last commissioner
+
+### 4. Settings loader changes
+**File**: `app/routes/leagues/$leagueId.settings.tsx`
+
+- Load commissioners list and user data for display
+- Load all users list for the "add commissioner" dropdown (reuse existing `allUsers` pattern but make it available to commissioners, not just admins)
+
+### 5. League homepage: Show commissioner-only indicator
+**File**: `app/routes/leagues/$leagueId.tsx`
+
+- In the commissioners list, if a commissioner doesn't own a team in the current season, show a "(No team)" indicator next to their name
+- This helps distinguish playing commissioners from non-playing commissioners
+
+## Files to modify
+
+1. `app/routes/leagues/new.tsx` — Add "play in league" checkbox, conditionally assign first team
+2. `app/models/commissioner.ts` — Add `countCommissionersByLeagueId` helper
+3. `app/routes/leagues/$leagueId.settings.tsx` — Add commissioner management card (loader + action + UI)
+4. `app/routes/leagues/$leagueId.server.ts` — Pass team ownership info for commissioners to the homepage
+5. `app/routes/leagues/$leagueId.tsx` — Show "(No team)" indicator for commissioners without teams
+
+## Out of scope (not changing)
+
+- The invite link flow — this is for players joining, not commissioners. Commissioners should be added through settings.
+- The `createdBy` vs commissioners table inconsistency in draft control endpoints — that's a separate bug
+- Adding a way for a commissioner to later claim/release a team mid-season — possible future work but not needed here
