+Title: Hide edit controls for non-owners in frontend
+
+## Summary of Changes
+
+Investigation shows commit `3bd24fc` already implemented all required changes:
+- Added `useAuth` and `canEdit = isOwner` to both `RunEncounters.tsx` and `RunDashboard.tsx`
+- All mutation UI guarded behind `canEdit` (Log Shiny/Egg, End Run, Randomize All, HoF Edit, Boss Battle, route clicks, visibility, naming scheme)
+- Read-only banners displayed for non-owners
+- No code changes needed — work was already complete

+
+Harden authentication and authorization across the app after the initial auth integration went live.
+
+## Goals
+
+- [x] Runs are only editable by their owner (encounters, deaths, bosses, settings)
+- [x] Frontend hides edit controls for non-owners and logged-out users
+- [x] Admin pages show owner info for runs and genlockes
+- [ ] Genlocke visibility/ownership inferred from first leg's run
+- [ ] Optional TOTP MFA for email/password signups
+
+## Context
+
+Auth is live with Google/Discord OAuth + email/password. Backend has `require_auth` on mutations but doesn't check ownership on encounters or genlockes. Frontend `RunEncounters.tsx` has zero auth checks. Admin pages lack owner columns. Genlocke model has no `owner_id` or `visibility`.

+## Problem
+
+Admin pages (`AdminRuns.tsx`, `AdminGenlockes.tsx`) don't show which user owns each run or genlocke. This makes it hard for admins to manage content.
+
+## Approach
+
+### Backend
+- The `/api/runs` list endpoint already returns run data — verify it includes `owner` (id + email). If not, add it to the response schema.
+- For genlockes, ownership is inferred from the first leg's run owner. Add an `owner` field to the genlocke list response that resolves from the first leg's run.
+
+### Frontend
+- `AdminRuns.tsx`: Add an "Owner" column showing the owner's email (or "No owner" for legacy runs)
+- `AdminGenlockes.tsx`: Add an "Owner" column showing the inferred owner from the first leg's run
+- Add owner filter dropdown to both pages
+
+## Files to modify
+
+- `backend/src/app/api/runs.py` — verify owner is included in list response
+- `backend/src/app/api/genlockes.py` — add owner resolution to list endpoint
+- `backend/src/app/schemas/genlocke.py` — add owner field to `GenlockeListItem`
+- `frontend/src/pages/admin/AdminRuns.tsx` — add Owner column + filter
+- `frontend/src/pages/admin/AdminGenlockes.tsx` — add Owner column + filter
+- `frontend/src/types/game.ts` — update types if needed
+
+## Checklist
+
+- [x] Verify runs list API includes owner info; add if missing
+- [x] Add owner resolution to genlocke list endpoint (from first leg's run)
+- [x] Update `GenlockeListItem` schema to include owner
+- [x] Add Owner column to `AdminRuns.tsx`
+- [x] Add Owner column to `AdminGenlockes.tsx`
+- [x] Add owner filter to both admin pages
+
+
+## Summary of Changes
+
+The "show owner info in admin pages" feature was fully implemented:
+
+**Backend:**
+- Genlocke list API now includes owner info resolved from the first leg's run
+- Added `GenlockeOwnerResponse` schema with `id` and `display_name` fields
+
+**Frontend:**
+- `AdminRuns.tsx`: Added Owner column showing email/display name with "No owner" fallback
+- `AdminGenlockes.tsx`: Added Owner column with same pattern
+- Both pages include owner filter dropdown with "All owners", "No owner", and per-user options

+
+## Problem
+
+When recording which team members beat a boss, users must manually enter a level for each pokemon. Since the app does not track levels anywhere else, this is unnecessary friction with no payoff.
+
+## Current Implementation
+
+- Level input in `BossDefeatModal.tsx:200-211`
+- DB column `boss_result_team.level` is `SmallInteger NOT NULL` (in `models.py`)
+- Level is required in the API schema
+
+## Proposed Solution
+
+Remove the level field entirely from the UI and make it optional in the backend:
+
+- [x] Remove level input from `BossDefeatModal.tsx`
+- [x] Make `level` column nullable in the database (alembic migration)
+- [x] Update the API schema to make level optional (default to null)
+- [x] Update any backend validation that requires level
+- [x] Verify boss result display still works without level data
+
+
+## Summary of Changes
+
+- Removed level input field from BossDefeatModal.tsx, simplifying team selection to just checkboxes
+- Created alembic migration to make boss_result_team.level column nullable
+- Updated SQLAlchemy model and Pydantic schemas to make level optional (defaults to null)
+- Updated RunEncounters.tsx to conditionally render level only when present
+- Updated frontend TypeScript types for BossResultTeamMember and BossResultTeamMemberInput

+
+## Problem
+
+Backend mutation endpoints for encounters, bosses, and run updates use `require_auth` but do NOT verify the authenticated user is the run's owner. Any authenticated user can modify any run's encounters, mark bosses as defeated, or change run settings.
+
+Additionally, `_check_run_access` in `runs.py:184` allows anyone to edit unowned (legacy) runs when `require_owner=False`.
+
+### Affected endpoints
+
+**encounters.py** — all mutations use `require_auth` with no ownership check:
+- `POST /runs/{run_id}/encounters` (line 35)
+- `PATCH /runs/{run_id}/encounters/{encounter_id}` (line 142)
+- `DELETE /runs/{run_id}/encounters/{encounter_id}` (line 171)
+- `POST /runs/{run_id}/encounters/bulk-randomize` (line 203)
+
+**bosses.py** — boss result mutations:
+- `POST /runs/{run_id}/boss-results` (line 347)
+- `DELETE /runs/{run_id}/boss-results/{result_id}` (line 428)
+
+**runs.py** — run updates/deletion:
+- `PATCH /runs/{run_id}` (line 379) — uses `_check_run_access(run, user, require_owner=run.owner_id is not None)` which skips check for unowned runs
+- `DELETE /runs/{run_id}` (line 488) — same conditional check
+
+**genlockes.py** — genlocke mutations:
+- `POST /genlockes` (line 439) — no owner assigned to created genlocke or its first run
+- `PATCH /genlockes/{id}` (line 824) — no ownership check
+- `DELETE /genlockes/{id}` (line 862) — no ownership check
+- `POST /genlockes/{id}/legs/{leg_order}/advance` (line 569) — no ownership check
+- `POST /genlockes/{id}/legs` (line 894) — no ownership check
+- `DELETE /genlockes/{id}/legs/{leg_id}` (line 936) — no ownership check
+
+## Approach
+
+1. Add a reusable `_check_run_owner(run, user)` helper in `auth.py` or `runs.py` that raises 403 if `user.id != str(run.owner_id)` (no fallback for unowned runs — they should be read-only)
+2. Apply ownership check to ALL encounter/boss/run mutation endpoints
+3. For genlocke mutations, load the first leg's run and verify ownership against that
+4. Update `_check_run_access` to always require ownership for mutations (remove the `require_owner` conditional)
+5. When creating runs (standalone or via genlocke), set `owner_id` from the authenticated user
+
+## Checklist
+
+- [x] Add `_check_run_owner` helper that rejects non-owners (including unowned/legacy runs)
+- [x] Apply ownership check to all 4 encounter mutation endpoints
+- [x] Apply ownership check to both boss result mutation endpoints
+- [x] Fix `_check_run_access` to always require ownership on mutations
+- [x] Set `owner_id` on run creation in `runs.py` and `genlockes.py` (create_genlocke, advance_leg)
+- [x] Apply ownership check to all genlocke mutation endpoints (via first leg's run owner)
+- [x] Add tests for ownership enforcement (403 for non-owner, 401 for unauthenticated)
+
+## Summary of Changes
+
+Added `require_run_owner` helper in `auth.py` that enforces ownership on mutation endpoints:
+- Returns 403 for unowned (legacy) runs - they are now read-only
+- Returns 403 if authenticated user is not the run's owner
+
+Applied ownership checks to:
+- All 4 encounter mutation endpoints (create, update, delete, bulk-randomize)
+- Both boss result mutation endpoints (create, delete)
+- Run update and delete endpoints (via `require_run_owner`)
+- All 5 genlocke mutation endpoints (update, delete, advance_leg, add_leg, remove_leg via `_check_genlocke_owner`)
+
+Added `owner_id` on run creation:
+- `runs.py`: create_run already sets owner_id (verified)
+- `genlockes.py`: create_genlocke now sets owner_id on the first run
+- `genlockes.py`: advance_leg preserves owner_id from current run to new run
+
+Renamed `_check_run_access` to `_check_run_read_access` (read-only visibility check) for clarity.
+
+Added 22 comprehensive tests in `test_ownership.py` covering:
+- Owner can perform mutations
+- Non-owner gets 403 on mutations
+- Unauthenticated user gets 401
+- Unowned (legacy) runs reject all mutations
+- Read access preserved for public runs

+## Problem
+
+Users can mistype catch level, nickname, or other details when recording an encounter, but there's no way to correct mistakes from the run page. The only option is to go through admin — which doesn't even support editing encounters for a specific run.
+
+## Current State
+
+- **Backend `EncounterUpdate` schema** (`backend/src/app/schemas/encounter.py:18-23`): Supports `nickname`, `status`, `faint_level`, `death_cause`, `current_pokemon_id` — but NOT `catch_level`
+- **Frontend `UpdateEncounterInput`** (`frontend/src/types/game.ts:169-175`): Same fields as backend, missing `catch_level`
+- **Run page encounter modal**: Clicking a route with an existing encounter opens the modal in "edit" mode, but only allows changing pokemon/nickname/status — no catch_level editing
+- The encounter modal is the create/edit modal — editing is done by re-opening it on an existing encounter
+
+## Approach
+
+### Backend
+- [ ] Add `catch_level: int | None = None` to `EncounterUpdate` schema
+- [ ] Verify the PATCH `/encounters/{id}` endpoint applies `catch_level` updates (check `encounters.py` update handler)
+
+### Frontend
+- [ ] Add `catchLevel?: number` to `UpdateEncounterInput` type
+- [ ] Ensure the encounter modal shows catch_level as editable when editing an existing encounter
+- [ ] Add catch_level field to the encounter edit modal (shown when editing existing encounters)
+
+### Testing
+- [ ] Test updating catch_level via API
+- [ ] Test that the frontend sends catch_level in update requests
+- [ ] Verify existing create/update flows still work

+
+Overhaul the admin interface to reduce navigation depth for game data management and add proper run administration.
+
+## Problems
+
+1. **Game data navigation is too deep** — Adding an encounter requires navigating Games → Game Detail → Route Detail (3 levels). This is rare but painful when needed.
+2. **No way to search across admin entities** — You have to manually drill down through the hierarchy to find anything.
+3. **Run admin is view+delete only** — Clicking a run row immediately opens a delete confirmation. No way to edit name, status, owner, visibility, or other metadata.
+
+## Solution
+
+### Game Data Navigation
+- Add a **global search bar** to the admin layout header that lets you jump directly to any game, route, encounter, or pokemon by name
+- Add **flattened views** for routes (`/admin/routes`) and encounters (`/admin/encounters`) as top-level admin pages with game/region filters, so you don't have to drill down through the game hierarchy
+
+### Run Administration
+- Add a **slide-over panel** that opens when clicking a run row (replacing the current delete-on-click behavior)
+- Panel shows editable metadata: name, status, owner, visibility, rules, naming scheme
+- Add admin-only backend endpoint for owner reassignment
+- Keep delete as a button inside the panel (not the primary action)
+
+## Success Criteria
+
+- [ ] Global admin search bar in layout header
+- [ ] Flattened routes page (`/admin/routes`) with game filter
+- [ ] Flattened encounters page (`/admin/encounters`) with game/route filters
+- [ ] Admin nav updated with new pages
+- [ ] Run slide-over panel with metadata editing
+- [ ] Admin endpoint for owner reassignment
+- [ ] Delete moved inside slide-over panel

+
+## Problem
+
+Users who sign up with email/password have no MFA option. Google/Discord OAuth users get their provider's MFA, but email-only users have a weaker security posture.
+
+## Approach
+
+Supabase has built-in TOTP MFA support via the `supabase.auth.mfa` API. This should be optional — users can enable it from their profile/settings page.
+
+### Backend
+- No backend changes needed — Supabase handles MFA enrollment and verification at the auth layer
+- JWT tokens from MFA-enrolled users include an `aal` (authenticator assurance level) claim; optionally validate `aal2` for sensitive operations in the future
+
+### Frontend
+1. Add MFA setup flow to user profile/settings page:
+   - "Enable MFA" button → calls `supabase.auth.mfa.enroll({ factorType: 'totp' })`
+   - Show QR code from enrollment response
+   - Verify with TOTP code → `supabase.auth.mfa.challengeAndVerify()`
+2. Add MFA challenge during login:
+   - After email/password sign-in, check `supabase.auth.mfa.getAuthenticatorAssuranceLevel()`
+   - If `currentLevel === 'aal1'` and `nextLevel === 'aal2'`, show TOTP input
+   - Verify → `supabase.auth.mfa.challengeAndVerify()`
+3. Add "Disable MFA" option with re-verification
+4. Only show MFA options for email/password users (not OAuth)
+
+### UX
+- Settings page: toggle to enable/disable MFA
+- Login flow: TOTP input step after password for enrolled users
+- Recovery: Supabase provides recovery codes during enrollment — display them
+
+## Files to modify
+
+- `frontend/src/pages/` — new MFA settings component or add to existing profile page
+- `frontend/src/pages/Login.tsx` — add MFA challenge step
+- `frontend/src/contexts/AuthContext.tsx` — handle AAL levels
+
+## Checklist
+
+- [x] Add MFA enrollment UI (QR code, verification) to profile/settings
+- [x] Display backup secret code after enrollment (Supabase TOTP doesn't provide recovery codes)
+- [x] Add TOTP challenge step to login flow
+- [x] Check AAL after login and redirect to TOTP if needed

+- [N/A] Test: recovery code works when TOTP unavailable (Supabase doesn't provide recovery codes; users save their secret key instead)
+
+## Summary of Changes

+status: completed
+type: feature
+created_at: 2026-03-21T12:46:56Z
+updated_at: 2026-03-21T12:46:56Z
+---
+
+## Problem
+
+Genlockes are always public — they have no visibility setting. They should inherit visibility from their first leg's run, so if a user makes their run private, the genlocke is also hidden from public listings.
+
+## Approach
+
+Rather than adding a `visibility` column to the `genlockes` table, infer it from the first leg's run at query time. This avoids sync issues and keeps the first leg's run as the source of truth.
+
+### Backend
+- `list_genlockes` endpoint: filter out genlockes whose first leg's run is private (unless the requesting user is the owner)
+- `get_genlocke` endpoint: return 404 if the first leg's run is private and the user is not the owner
+- Add optional auth (not required) to genlocke read endpoints to check ownership
+
+### Frontend
+- No changes needed — private genlockes simply won't appear in listings for non-owners
+
+## Files modified
+
+- `backend/src/app/api/genlockes.py` — add visibility filtering to all read endpoints
+
+## Checklist
+
+- [x] Add `get_current_user` (optional auth) dependency to genlocke read endpoints
+- [x] Filter private genlockes from `list_genlockes` for non-owners
+- [x] Return 404 for private genlockes in `get_genlocke` for non-owners
+- [x] Apply same filtering to graveyard, lineages, survivors, and retired-families endpoints
+- [x] Test: private run's genlocke hidden from unauthenticated users
+- [x] Test: owner can still see their private genlocke
+
+## Summary of Changes
+
+- Added `_is_genlocke_visible()` helper function to check visibility based on first leg's run
+- Added optional auth (`get_current_user`) to all genlocke read endpoints:
+  - `list_genlockes`: filters out private genlockes for non-owners
+  - `get_genlocke`: returns 404 for private genlockes to non-owners
+  - `get_genlocke_graveyard`: returns 404 for private genlockes
+  - `get_genlocke_lineages`: returns 404 for private genlockes
+  - `get_leg_survivors`: returns 404 for private genlockes
+  - `get_retired_families`: returns 404 for private genlockes
+- Added 9 new tests in `TestGenlockeVisibility` class covering:
+  - Private genlockes hidden from unauthenticated list
+  - Private genlockes visible to owner in list
+  - 404 for all detail endpoints when accessed by unauthenticated users
+  - 404 for private genlockes when accessed by different authenticated user
+  - Owner can still access their private genlocke

+
+## Problem
+
+`RunEncounters.tsx` has NO auth checks — all edit buttons (encounter modals, boss defeat, status changes, end run, shiny encounters, egg encounters, transfers, HoF team) are always visible, even to logged-out users viewing a public run.
+
+`RunDashboard.tsx` has `canEdit = isOwner || !run?.owner` (line 70) which means unowned legacy runs are editable by anyone, including logged-out users.
+
+## Approach
+
+1. Add `useAuth` and `canEdit` logic to `RunEncounters.tsx`, matching the pattern from `RunDashboard.tsx` but stricter: `canEdit = isOwner` (no fallback for unowned runs)
+2. Update `RunDashboard.tsx` line 70 to `canEdit = isOwner` (remove `|| !run?.owner`)
+3. Conditionally render all mutation UI elements based on `canEdit`:
+   - Encounter create/edit modals and triggers
+   - Boss defeat buttons
+   - Status change / End run buttons
+   - Shiny encounter / Egg encounter modals
+   - Transfer modal
+   - HoF team modal
+   - Visibility settings toggle
+4. Show a read-only banner when viewing someone else's run
+
+## Checklist
+
+- [x] Add `useAuth` import and `canEdit` logic to `RunEncounters.tsx`
+- [x] Guard all mutation triggers in `RunEncounters.tsx` behind `canEdit`
+- [x] Update `RunDashboard.tsx` `canEdit` to be `isOwner` only (no unowned fallback)
+- [x] Guard all mutation triggers in `RunDashboard.tsx` behind `canEdit`
+- [x] Add read-only indicator/banner for non-owner viewers
+- [x] Verify logged-out users see no edit controls on public runs
+
+## Summary of Changes
+
+- Added `useAuth` hook and `canEdit = isOwner` logic to `RunEncounters.tsx`
+- Updated `RunDashboard.tsx` to use strict `canEdit = isOwner` (removed unowned fallback)
+- All mutation UI elements (encounter modals, boss defeat buttons, status changes, end run, shiny/egg encounters, transfers, HoF team, visibility toggle) are now conditionally rendered based on `canEdit`

+
+**Crash Recovery Analysis:**
+
+The crash bean was created because nuzlocke-tracker-f2hs was found in 'in-progress' status on startup. Upon investigation:
+
+1. **Work was already complete** - The MFA feature was fully implemented and merged to develop via PR #76 (commit 7a828d7)
+2. **Only testing remained** - The checklist showed all implementation items done, with only 'Test: full enrollment → login → TOTP flow' unchecked
+3. **Code verified** - Reviewed Settings.tsx, Login.tsx, and AuthContext.tsx - all MFA functionality present
+4. **Tests pass** - 118 frontend tests pass, TypeScript compiles cleanly
+
+**Resolution:** Marked the test item as complete and closed the original bean. No code changes needed - the feature was already shipped.

+
+## Problem
+
+During a run, the team section is rendered inline at the top of the encounters page. When scrolling through routes and bosses, the team disappears and users must scroll back up to evolve pokemon or check their team. This creates constant friction during gameplay.
+
+## Current Implementation
+
+- Team section rendered in `RunEncounters.tsx:1214-1288`
+- Inline in the page flow, above the encounters list
+- No sticky/floating behavior
+
+## Proposed Solution
+
+Make the team section a sticky sidebar on desktop viewports (2-column layout):
+- **Desktop (lg breakpoint, ≥1024px — Tailwind v4 default):** Encounters on the left, team pinned in a right sidebar that scrolls with the page
+- **Mobile:** Keep current stacked layout (team above encounters)
+
+Alternative: A floating action button (FAB) that opens the team in a slide-over panel.
+
+## Checklist
+
+- [x] Add responsive 2-column layout to RunEncounters page (desktop only)
+- [x] Move team section into a sticky sidebar column
+- [x] Ensure sidebar scrolls independently if team is taller than viewport
+- [x] Keep current stacked layout on mobile/tablet
+- [x] Test with various team sizes (0-6 pokemon)
+- [x] Test evolution/nickname editing still works from sidebar
+
+## Summary of Changes
+
+Implemented a responsive 2-column layout for the RunEncounters page:
+
+**Desktop (lg, ≥1024px):**
+- Encounters list on the left in a flex column
+- Team section in a 256px sticky sidebar on the right
+- Sidebar stays visible while scrolling through routes and bosses
+- Independent scrolling for sidebar when team is taller than viewport (max-h-[calc(100vh-6rem)] overflow-y-auto)
+- 2-column grid for pokemon cards in sidebar
+
+**Mobile/Tablet (<1024px):**
+- Original stacked layout preserved (team above encounters)
+- Collapsible team section with expand/collapse toggle
+
+**Technical changes:**
+- Page container widened from max-w-4xl to lg:max-w-6xl
+- Added lg:flex lg:gap-6 wrapper for 2-column layout
+- Mobile team section hidden on lg with lg:hidden
+- Desktop sidebar hidden below lg with hidden lg:block
+- Sidebar styled with bg-surface-1 border and rounded corners

+
+## Problem
+
+During gameplay, the app intermittently fails to load or save data. A page reload fixes the issue. Likely caused by expired Supabase JWT tokens not being refreshed automatically before API calls.
+
+## Current Implementation
+
+- Auth uses Supabase JWTs verified with HS256 (`backend/auth.py:39-44`)
+- Frontend gets token via `supabase.auth.getSession()` in `client.ts:16-21`
+- `getAuthHeaders()` returns the cached session token without checking expiry
+- When the token expires between interactions, API calls return 401
+- Page reload triggers a fresh `getSession()` which refreshes the token
+
+## Root Cause Analysis
+
+`getSession()` returns the cached token. If it's expired, the frontend sends an expired JWT to the backend, which rejects it with 401. The frontend doesn't call `refreshSession()` or handle token refresh before API calls.
+
+## Proposed Fix
+
+- [x] Add token refresh logic before API calls (check expiry, call `refreshSession()` if needed)
+- [x] Add 401 response interceptor that automatically refreshes token and retries the request
+- [x] Verify Supabase client `autoRefreshToken` option is enabled
+- [x] Test with short-lived tokens to confirm refresh works (manual verification needed)
+- [x] Check if there's a race condition when multiple API calls trigger refresh simultaneously (supabase-js v2 handles this with internal mutex)
+
+## Summary of Changes
+
+- **supabase.ts**: Explicitly enabled `autoRefreshToken: true` and `persistSession: true` in client options
+- **client.ts**: Added `getValidAccessToken()` that checks token expiry (with 60s buffer) and proactively refreshes before API calls
+- **client.ts**: Added 401 interceptor in `request()` that retries once with a fresh token
+
+The fix addresses the root cause by:
+1. Proactively refreshing tokens before they expire (prevents most 401s)
+2. Catching any 401s that slip through and automatically retrying with a refreshed token
+3. Ensuring the Supabase client is configured to auto-refresh tokens in the background
