Session Notes Read/Edit/Delete Implementation Plan

For agentic workers: REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (- [ ]) syntax for tracking.

Goal: Add the ability to view, edit, and delete session notes — with notes previews on the History page and a new Session Detail page with full markdown rendering and inline editing.

Architecture: Backend adds two new endpoints (PUT/DELETE notes) and modifies two existing ones (list sessions omits full notes, single session gates notes on auth). A new optional-auth middleware enables the conditional response. Frontend adds a new SessionDetail page at /history/:id with react-markdown for rendering, and simplifies the History page to a session list with navigation.

Tech Stack: Node.js/Express, better-sqlite3, JWT auth, React 18, React Router, Tailwind CSS, react-markdown

Spec: docs/superpowers/specs/2026-03-22-session-notes-read-edit-delete-design.md

Task 1: Notes Preview Helper

Create a utility function to compute has_notes and notes_preview from a raw notes string.

Files:

Create: backend/utils/notes-preview.js
Create: tests/api/session-notes.test.js
Step 1: Write failing tests for notesPreview helper

In tests/api/session-notes.test.js:

const { computeNotesPreview } = require('../../backend/utils/notes-preview');

describe('computeNotesPreview', () => {
  test('returns has_notes false and null preview for null input', () => {
    const result = computeNotesPreview(null);
    expect(result).toEqual({ has_notes: false, notes_preview: null });
  });

  test('returns has_notes false and null preview for empty string', () => {
    const result = computeNotesPreview('');
    expect(result).toEqual({ has_notes: false, notes_preview: null });
  });

  test('returns first paragraph as preview', () => {
    const notes = 'First paragraph here.\n\nSecond paragraph here.';
    const result = computeNotesPreview(notes);
    expect(result.has_notes).toBe(true);
    expect(result.notes_preview).toBe('First paragraph here.');
  });

  test('strips markdown bold formatting', () => {
    const notes = '**Bold text** and more';
    const result = computeNotesPreview(notes);
    expect(result.notes_preview).toBe('Bold text and more');
  });

  test('strips markdown italic formatting', () => {
    const notes = '*Italic text* and _also italic_';
    const result = computeNotesPreview(notes);
    expect(result.notes_preview).toBe('Italic text and also italic');
  });

  test('strips markdown links', () => {
    const notes = 'Check [this link](http://example.com) out';
    const result = computeNotesPreview(notes);
    expect(result.notes_preview).toBe('Check this link out');
  });

  test('strips markdown headers', () => {
    const notes = '## Header text';
    const result = computeNotesPreview(notes);
    expect(result.notes_preview).toBe('Header text');
  });

  test('strips markdown list markers', () => {
    const notes = '- Item one\n- Item two';
    const result = computeNotesPreview(notes);
    expect(result.notes_preview).toBe('Item one Item two');
  });

  test('truncates to 150 characters with ellipsis', () => {
    const notes = 'A'.repeat(200);
    const result = computeNotesPreview(notes);
    expect(result.notes_preview).toHaveLength(153); // 150 + '...'
    expect(result.notes_preview.endsWith('...')).toBe(true);
  });

  test('does not truncate text at or under 150 characters', () => {
    const notes = 'A'.repeat(150);
    const result = computeNotesPreview(notes);
    expect(result.notes_preview).toHaveLength(150);
    expect(result.notes_preview).not.toContain('...');
  });
});

Step 2: Run tests to verify they fail

Run: npx jest tests/api/session-notes.test.js --verbose Expected: FAIL — Cannot find module '../../backend/utils/notes-preview'

Step 3: Implement computeNotesPreview

Create backend/utils/notes-preview.js:

function computeNotesPreview(notes) {
  if (!notes || notes.trim() === '') {
    return { has_notes: false, notes_preview: null };
  }

  const firstParagraph = notes.split(/\n\n/)[0];

  const stripped = firstParagraph
    .replace(/^#{1,6}\s+/gm, '')       // headers
    .replace(/\*\*(.+?)\*\*/g, '$1')   // bold
    .replace(/\*(.+?)\*/g, '$1')       // italic with *
    .replace(/_(.+?)_/g, '$1')         // italic with _
    .replace(/\[([^\]]+)\]\([^)]+\)/g, '$1') // links
    .replace(/^[-*+]\s+/gm, '')        // list markers
    .replace(/\n/g, ' ')               // collapse remaining newlines
    .replace(/\s+/g, ' ')              // collapse whitespace
    .trim();

  const truncated = stripped.length > 150
    ? stripped.slice(0, 150) + '...'
    : stripped;

  return { has_notes: true, notes_preview: truncated };
}

module.exports = { computeNotesPreview };

Step 4: Run tests to verify they pass

Run: npx jest tests/api/session-notes.test.js --verbose Expected: All tests PASS

Step 5: Commit

git add backend/utils/notes-preview.js tests/api/session-notes.test.js
git commit -m "feat: add notes preview helper with tests"

Task 2: Optional Auth Middleware

Create a middleware that checks for auth but doesn't reject the request if missing/invalid — just sets req.user to null.

Files:

Create: backend/middleware/optional-auth.js
Test: inline in tests/api/session-notes.test.js
Step 1: Write failing tests for optional auth behavior

Add to tests/api/session-notes.test.js (new describe block at the bottom — these tests depend on the API endpoint changes in Task 4, so they will be written now but run after Task 4):

const request = require('supertest');
const { app } = require('../../backend/server');
const { cleanDb, getAuthHeader, seedSession } = require('../helpers/test-utils');

describe('GET /api/sessions/:id notes visibility', () => {
  beforeEach(() => {
    cleanDb();
  });

  test('returns full notes when authenticated', async () => {
    const session = seedSession({ notes: '**Full notes** here\n\nSecond paragraph' });

    const res = await request(app)
      .get(`/api/sessions/${session.id}`)
      .set('Authorization', getAuthHeader());

    expect(res.status).toBe(200);
    expect(res.body.notes).toBe('**Full notes** here\n\nSecond paragraph');
    expect(res.body.has_notes).toBe(true);
    expect(res.body.notes_preview).toBe('Full notes here');
  });

  test('returns only preview when unauthenticated', async () => {
    const session = seedSession({ notes: '**Full notes** here\n\nSecond paragraph' });

    const res = await request(app)
      .get(`/api/sessions/${session.id}`);

    expect(res.status).toBe(200);
    expect(res.body.notes).toBeUndefined();
    expect(res.body.has_notes).toBe(true);
    expect(res.body.notes_preview).toBe('Full notes here');
  });

  test('returns has_notes false when no notes', async () => {
    const session = seedSession({ notes: null });

    const res = await request(app)
      .get(`/api/sessions/${session.id}`);

    expect(res.status).toBe(200);
    expect(res.body.has_notes).toBe(false);
    expect(res.body.notes_preview).toBeNull();
  });
});

Step 2: Implement optionalAuthenticateToken middleware

Create backend/middleware/optional-auth.js:

const jwt = require('jsonwebtoken');
const { JWT_SECRET } = require('./auth');

function optionalAuthenticateToken(req, res, next) {
  const authHeader = req.headers['authorization'];
  const token = authHeader && authHeader.split(' ')[1];

  if (!token) {
    req.user = null;
    return next();
  }

  jwt.verify(token, JWT_SECRET, (err, user) => {
    req.user = err ? null : user;
    next();
  });
}

module.exports = { optionalAuthenticateToken };

Step 3: Commit

git add backend/middleware/optional-auth.js
git commit -m "feat: add optional auth middleware"

Task 3: Modify GET /api/sessions (list endpoint)

Replace s.* with explicit columns, add has_notes and notes_preview, omit full notes.

Files:

Modify: backend/routes/sessions.js:20-36 (GET / handler)
Test: tests/api/session-notes.test.js
Step 1: Write failing tests for list endpoint changes

Add to tests/api/session-notes.test.js:

describe('GET /api/sessions list', () => {
  beforeEach(() => {
    cleanDb();
  });

  test('includes has_notes and notes_preview in list response', async () => {
    seedSession({ notes: '**Bold** first paragraph\n\nSecond paragraph' });
    seedSession({ notes: null });

    const res = await request(app).get('/api/sessions');

    expect(res.status).toBe(200);
    expect(res.body).toHaveLength(2);

    const withNotes = res.body.find(s => s.has_notes === true);
    const withoutNotes = res.body.find(s => s.has_notes === false);

    expect(withNotes.notes_preview).toBe('Bold first paragraph');
    expect(withNotes).not.toHaveProperty('notes');

    expect(withoutNotes.notes_preview).toBeNull();
    expect(withoutNotes).not.toHaveProperty('notes');
  });

  test('list response preserves existing fields', async () => {
    seedSession({ is_active: 1, notes: 'Test' });

    const res = await request(app).get('/api/sessions');

    expect(res.status).toBe(200);
    expect(res.body[0]).toHaveProperty('id');
    expect(res.body[0]).toHaveProperty('created_at');
    expect(res.body[0]).toHaveProperty('closed_at');
    expect(res.body[0]).toHaveProperty('is_active');
    expect(res.body[0]).toHaveProperty('games_played');
  });
});

Step 2: Run tests to verify they fail

Run: npx jest tests/api/session-notes.test.js --verbose --testNamePattern="list" Expected: FAIL — notes still present in response, has_notes and notes_preview missing

Step 3: Modify the GET / handler in sessions.js

In backend/routes/sessions.js, replace the GET / handler (lines 20-36):

const { computeNotesPreview } = require('../utils/notes-preview');

Add this import at the top of the file (after existing imports).

Replace the handler body:

router.get('/', (req, res) => {
  try {
    const sessions = db.prepare(`
      SELECT 
        s.id,
        s.created_at,
        s.closed_at,
        s.is_active,
        s.notes,
        COUNT(sg.id) as games_played
      FROM sessions s
      LEFT JOIN session_games sg ON s.id = sg.session_id
      GROUP BY s.id
      ORDER BY s.created_at DESC
    `).all();

    const result = sessions.map(({ notes, ...session }) => {
      const { has_notes, notes_preview } = computeNotesPreview(notes);
      return { ...session, has_notes, notes_preview };
    });

    res.json(result);
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
});

Note: We still SELECT notes from the DB to compute the preview, but destructure it out of the response object so it's never sent to the client.

Step 4: Run tests to verify they pass

Run: npx jest tests/api/session-notes.test.js --verbose --testNamePattern="list" Expected: PASS

Step 5: Commit

git add backend/routes/sessions.js tests/api/session-notes.test.js
git commit -m "feat: add has_notes and notes_preview to session list, omit full notes"

Task 4: Modify GET /api/sessions/:id (single session)

Gate full notes behind auth; always return has_notes and notes_preview.

Files:

Modify: backend/routes/sessions.js:64-84 (GET /:id handler)
Modify: tests/api/regression-sessions.test.js (update existing test expectations)
Step 1: Run the existing regression tests to confirm they pass before changes

Run: npx jest tests/api/regression-sessions.test.js --verbose Expected: PASS

Step 2: Modify the GET /:id handler

In backend/routes/sessions.js, add the import at the top (if not already added in Task 3):

const { optionalAuthenticateToken } = require('../middleware/optional-auth');

Replace the GET /:id handler (lines 64-84):

router.get('/:id', optionalAuthenticateToken, (req, res) => {
  try {
    const session = db.prepare(`
      SELECT 
        s.*,
        COUNT(sg.id) as games_played
      FROM sessions s
      LEFT JOIN session_games sg ON s.id = sg.session_id
      WHERE s.id = ?
      GROUP BY s.id
    `).get(req.params.id);

    if (!session) {
      return res.status(404).json({ error: 'Session not found' });
    }

    const { has_notes, notes_preview } = computeNotesPreview(session.notes);

    if (req.user) {
      res.json({ ...session, has_notes, notes_preview });
    } else {
      const { notes, ...publicSession } = session;
      res.json({ ...publicSession, has_notes, notes_preview });
    }
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
});

Step 3: Update regression test expectations

The existing test in tests/api/regression-sessions.test.js at line 10-24 expects notes in the response without auth. Update it:

  test('GET /api/sessions/:id returns session object with preview for unauthenticated', async () => {
    const session = seedSession({ is_active: 1, notes: 'Test session' });

    const res = await request(app).get(`/api/sessions/${session.id}`);

    expect(res.status).toBe(200);
    expect(res.body).toEqual(
      expect.objectContaining({
        id: session.id,
        is_active: 1,
        has_notes: true,
        notes_preview: 'Test session',
      })
    );
    expect(res.body.notes).toBeUndefined();
    expect(res.body).toHaveProperty('games_played');
  });

Step 4: Run all session-related tests

Run: npx jest tests/api/session-notes.test.js tests/api/regression-sessions.test.js --verbose Expected: All PASS (including the notes visibility tests written in Task 2 Step 1)

Step 5: Commit

git add backend/routes/sessions.js tests/api/regression-sessions.test.js tests/api/session-notes.test.js
git commit -m "feat: gate full notes behind auth on single session endpoint"

Task 5: Add PUT /api/sessions/:id/notes

New endpoint to update notes.

Files:

Modify: backend/routes/sessions.js
Test: tests/api/session-notes.test.js
Step 1: Write failing tests

Add to tests/api/session-notes.test.js:

describe('PUT /api/sessions/:id/notes', () => {
  beforeEach(() => {
    cleanDb();
  });

  test('updates notes when authenticated', async () => {
    const session = seedSession({ notes: 'Old notes' });

    const res = await request(app)
      .put(`/api/sessions/${session.id}/notes`)
      .set('Authorization', getAuthHeader())
      .send({ notes: 'New notes here' });

    expect(res.status).toBe(200);
    expect(res.body.notes).toBe('New notes here');
  });

  test('overwrites notes completely (no merge)', async () => {
    const session = seedSession({ notes: 'Original notes' });

    const res = await request(app)
      .put(`/api/sessions/${session.id}/notes`)
      .set('Authorization', getAuthHeader())
      .send({ notes: 'Replacement' });

    expect(res.status).toBe(200);
    expect(res.body.notes).toBe('Replacement');
  });

  test('returns 404 for nonexistent session', async () => {
    const res = await request(app)
      .put('/api/sessions/99999/notes')
      .set('Authorization', getAuthHeader())
      .send({ notes: 'test' });

    expect(res.status).toBe(404);
  });

  test('returns 401 without auth header', async () => {
    const session = seedSession({});

    const res = await request(app)
      .put(`/api/sessions/${session.id}/notes`)
      .send({ notes: 'test' });

    expect(res.status).toBe(401);
  });

  test('returns 403 with invalid token', async () => {
    const session = seedSession({});

    const res = await request(app)
      .put(`/api/sessions/${session.id}/notes`)
      .set('Authorization', 'Bearer invalid-token')
      .send({ notes: 'test' });

    expect(res.status).toBe(403);
  });
});

Step 2: Run tests to verify they fail

Run: npx jest tests/api/session-notes.test.js --verbose --testNamePattern="PUT" Expected: FAIL — 404 (route not found)

Step 3: Implement PUT /:id/notes

Add to backend/routes/sessions.js (after the DELETE /:id handler, before GET /:id/games):

router.put('/:id/notes', authenticateToken, (req, res) => {
  try {
    const { notes } = req.body;

    const session = db.prepare('SELECT id FROM sessions WHERE id = ?').get(req.params.id);
    if (!session) {
      return res.status(404).json({ error: 'Session not found' });
    }

    db.prepare('UPDATE sessions SET notes = ? WHERE id = ?').run(notes, req.params.id);

    const updated = db.prepare(`
      SELECT s.*, COUNT(sg.id) as games_played
      FROM sessions s
      LEFT JOIN session_games sg ON s.id = sg.session_id
      WHERE s.id = ?
      GROUP BY s.id
    `).get(req.params.id);

    res.json(updated);
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
});

Important route ordering note: This route must be placed before the GET /:id/games, GET /:id/votes, and other /:id/* routes to avoid conflicts. Since Express matches routes in registration order, PUT /:id/notes won't conflict with GET /:id/games because they use different HTTP methods. Place it right after DELETE /:id (line ~228).

Step 4: Run tests to verify they pass

Run: npx jest tests/api/session-notes.test.js --verbose --testNamePattern="PUT" Expected: PASS

Step 5: Commit

git add backend/routes/sessions.js tests/api/session-notes.test.js
git commit -m "feat: add PUT /api/sessions/:id/notes endpoint"

Task 6: Add DELETE /api/sessions/:id/notes

New endpoint to clear notes.

Files:

Modify: backend/routes/sessions.js
Test: tests/api/session-notes.test.js
Step 1: Write failing tests

Add to tests/api/session-notes.test.js:

describe('DELETE /api/sessions/:id/notes', () => {
  beforeEach(() => {
    cleanDb();
  });

  test('clears notes when authenticated', async () => {
    const session = seedSession({ notes: 'Some notes' });

    const res = await request(app)
      .delete(`/api/sessions/${session.id}/notes`)
      .set('Authorization', getAuthHeader());

    expect(res.status).toBe(200);
    expect(res.body.success).toBe(true);

    // Verify notes are actually cleared
    const check = await request(app)
      .get(`/api/sessions/${session.id}`)
      .set('Authorization', getAuthHeader());
    expect(check.body.notes).toBeNull();
    expect(check.body.has_notes).toBe(false);
  });

  test('returns 404 for nonexistent session', async () => {
    const res = await request(app)
      .delete('/api/sessions/99999/notes')
      .set('Authorization', getAuthHeader());

    expect(res.status).toBe(404);
  });

  test('returns 401 without auth header', async () => {
    const session = seedSession({ notes: 'test' });

    const res = await request(app)
      .delete(`/api/sessions/${session.id}/notes`);

    expect(res.status).toBe(401);
  });

  test('returns 403 with invalid token', async () => {
    const session = seedSession({ notes: 'test' });

    const res = await request(app)
      .delete(`/api/sessions/${session.id}/notes`)
      .set('Authorization', 'Bearer invalid-token');

    expect(res.status).toBe(403);
  });
});

Step 2: Run tests to verify they fail

Run: npx jest tests/api/session-notes.test.js --verbose --testNamePattern="DELETE.*notes" Expected: FAIL

Step 3: Implement DELETE /:id/notes

Add to backend/routes/sessions.js (right after the PUT /:id/notes handler):

router.delete('/:id/notes', authenticateToken, (req, res) => {
  try {
    const session = db.prepare('SELECT id FROM sessions WHERE id = ?').get(req.params.id);
    if (!session) {
      return res.status(404).json({ error: 'Session not found' });
    }

    db.prepare('UPDATE sessions SET notes = NULL WHERE id = ?').run(req.params.id);

    res.json({ success: true });
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
});

Place this right after the PUT /:id/notes handler. No route ordering concern here — DELETE /:id/notes (two path segments) won't conflict with DELETE /:id (one segment) regardless of registration order.

Step 4: Run tests to verify they pass

Run: npx jest tests/api/session-notes.test.js --verbose --testNamePattern="DELETE.*notes" Expected: PASS

Step 5: Run all backend tests to ensure no regressions

Run: npx jest --verbose Expected: All PASS

Step 6: Commit

git add backend/routes/sessions.js tests/api/session-notes.test.js
git commit -m "feat: add DELETE /api/sessions/:id/notes endpoint"

Task 7: Add react-markdown Frontend Dependency

Files:

Modify: frontend/package.json
Step 1: Install react-markdown and @tailwindcss/typography

The @tailwindcss/typography plugin provides prose classes used to style the rendered markdown output.

Run from the frontend/ directory:

cd frontend && npm install react-markdown @tailwindcss/typography

Step 2: Add typography plugin to Tailwind config

In frontend/tailwind.config.js, change the plugins line:

  plugins: [require('@tailwindcss/typography')],

Step 3: Verify installation

Run: cd frontend && npx vite build 2>&1 | tail -3 Expected: Build succeeds.

Step 4: Commit

git add frontend/package.json frontend/package-lock.json frontend/tailwind.config.js
git commit -m "chore: add react-markdown and @tailwindcss/typography dependencies"

Task 8: Create SessionDetail Page

The largest frontend task. New page component with notes view/edit, games list, and session actions.

Files:

Create: frontend/src/pages/SessionDetail.jsx
Modify: frontend/src/App.jsx
Step 1: Add route in App.jsx

Add import at the top of frontend/src/App.jsx (after the History import):

import SessionDetail from './pages/SessionDetail';

Add route inside <Routes> (after the /history route):

<Route path="/history/:id" element={<SessionDetail />} />

Step 2: Create SessionDetail.jsx — shell with data loading

Create frontend/src/pages/SessionDetail.jsx:

import React, { useState, useEffect, useCallback } from 'react';
import { useParams, useNavigate, Link } from 'react-router-dom';
import Markdown from 'react-markdown';
import { useAuth } from '../context/AuthContext';
import { useToast } from '../components/Toast';
import api from '../api/axios';
import { formatLocalDateTime, formatLocalTime } from '../utils/dateUtils';
import PopularityBadge from '../components/PopularityBadge';

function SessionDetail() {
  const { id } = useParams();
  const navigate = useNavigate();
  const { isAuthenticated } = useAuth();
  const { error: showError, success } = useToast();

  const [session, setSession] = useState(null);
  const [games, setGames] = useState([]);
  const [loading, setLoading] = useState(true);
  const [editing, setEditing] = useState(false);
  const [editedNotes, setEditedNotes] = useState('');
  const [saving, setSaving] = useState(false);
  const [showDeleteNotesConfirm, setShowDeleteNotesConfirm] = useState(false);
  const [showDeleteSessionConfirm, setShowDeleteSessionConfirm] = useState(false);
  const [showChatImport, setShowChatImport] = useState(false);
  const [closingSession, setClosingSession] = useState(false);

  const loadSession = useCallback(async () => {
    try {
      const res = await api.get(`/sessions/${id}`);
      setSession(res.data);
    } catch (err) {
      if (err.response?.status === 404) {
        navigate('/history', { replace: true });
      }
      console.error('Failed to load session', err);
    }
  }, [id, navigate]);

  const loadGames = useCallback(async () => {
    try {
      const res = await api.get(`/sessions/${id}/games`);
      setGames([...res.data].reverse());
    } catch (err) {
      console.error('Failed to load session games', err);
    }
  }, [id]);

  useEffect(() => {
    Promise.all([loadSession(), loadGames()]).finally(() => setLoading(false));
  }, [loadSession, loadGames]);

  useEffect(() => {
    if (!session || session.is_active !== 1) return;
    const interval = setInterval(() => {
      loadSession();
      loadGames();
    }, 3000);
    return () => clearInterval(interval);
  }, [session, loadSession, loadGames]);

  const handleSaveNotes = async () => {
    setSaving(true);
    try {
      await api.put(`/sessions/${id}/notes`, { notes: editedNotes });
      await loadSession();
      setEditing(false);

export default SessionDetail;

Step 3: Verify the app compiles

Run from frontend/:

cd frontend && npx vite build 2>&1 | tail -5

Expected: Build succeeds with no errors.

Step 4: Commit

git add frontend/src/pages/SessionDetail.jsx frontend/src/App.jsx
git commit -m "feat: add SessionDetail page with notes view/edit and route"

Task 9: Modify History Page

Simplify the History page: remove the inline detail panel, add notes preview to session cards, change clicks to navigate to /history/:id, remove delete button from closed sessions.

Files:

Modify: frontend/src/pages/History.jsx
Step 1: Replace History.jsx

The History page needs significant changes. Replace the entire History function component. Key changes:

Remove state: selectedSession, sessionGames, showChatImport
Remove functions: refreshSessionGames, loadSessionGames, handleExport, all polling for game updates
Remove the entire right-side detail panel (md:col-span-2)
Session cards: clicking navigates to /history/:id via useNavigate
Session cards: show notes_preview when has_notes is true
Session cards: remove Delete button for closed sessions (only End Session stays for active)
EndSessionModal stays (for ending active sessions from the list)
ChatImportPanel removed from this file (it's now in SessionDetail.jsx)
Delete confirmation modal removed from this file

Replace the History function in frontend/src/pages/History.jsx with:

import React, { useState, useEffect, useCallback } from 'react';

  const [showAllSessions, setShowAllSessions] = useState(false);

  const loadSessions = useCallback(async () => {
    try {
      const response = await api.get('/sessions');
      setSessions(response.data);
    } catch (err) {
      console.error('Failed to load sessions', err);
    } finally {
      setLoading(false);
    }
  }, []);

  useEffect(() => {
    loadSessions();
  }, [loadSessions]);

  useEffect(() => {
    const interval = setInterval(() => {
      loadSessions();
    }, 3000);
    return () => clearInterval(interval);
  }, [loadSessions]);

  const handleCloseSession = async (sessionId, notes) => {
    try {
      await api.post(`/sessions/${sessionId}/close`, { notes });
      await loadSessions();
      setClosingSession(null);
      success('Session ended successfully');
    } catch (err) {
      error('Failed to close session');
    }
  };

Note: The EndSessionModal here is simplified — it no longer receives sessionGames or onShowChatImport since the detailed chat import flow now lives on the SessionDetail page. The popularity warning is only shown on the SessionDetail page's EndSessionModal. The ChatImportPanel component is removed entirely from this file.

Step 2: Verify the app compiles

Run from frontend/:

cd frontend && npx vite build 2>&1 | tail -5

Expected: Build succeeds.

Step 3: Commit

git add frontend/src/pages/History.jsx
git commit -m "feat: simplify History page to session list with notes preview and navigation"
