Instead, we can suggest an additive approach that maintains backward compatibility.\n\n### Suggested Approach\n\n1. **Add a New Column (if necessary):** If there's any transitional data manipulation needed, you might add a new column temporarily.\n2. **Remove References in Code:** Update all code references to stop using `legacy_score`.\n3. **Deprecate the Column:** Mark the column as deprecated in comments or documentation but do not remove it from the schema.\n\n### Migration Steps\n\n1. **Update Code:**\n   - Remove any usage of `legacy_score` in the application code.\n   - Ensure all tests pass after removing these references.\n\n2. **Document Deprecation:**\n   - Add a comment in the database migration file or schema documentation to indicate that `legacy_score` is deprecated and will be removed in a future release.\n\n3. **Future Removal (Optional):**\n   - Plan for a future, separate migration phase where you can safely remove the column after ensuring no code references it and all environments have been updated.\n\n### Example Migration\n\nSince we cannot drop the column directly, here's how you might document the deprecation:\n\n```sql\n-- Migration to deprecate legacy_score in students table\nALTER TABLE students ADD COLUMN IF NOT EXISTS _deprecated_legacy_score INTEGER;\n\nCOMMENT ON COLUMN students.legacy_score IS 'DEPRECATED: This column is no longer used and will be removed in a future release.';\n```\n\n### What It Changes:\n- Adds a comment to the `legacy_score` column indicating it is deprecated.\n- Optionally, adds a new column `_deprecated_legacy_score` (if transitional data manipulation is needed).\n\n### What It Could Break:\n- Nothing directly, as we are not removing or altering the column's usage in any active code paths.\n\n### What Tests Verify It:\n- Ensure all tests pass after removing references to `legacy_score`",

However, if there are application-level constraints that expect this column to be non-null, those would need to be adjusted accordingly.\n\n### Tests To Verify:\n- Ensure that the new column exists in the `students` table.\n- Test inserting a new student record and verify that `last_login_at` is initially `NULL`.\n- Update an existing student's `last_login_at` field and verify that the update is successful.\n\n### Additional Considerations:\n- If you need to populate this field with default values for existing students, you can do so in a subsequent migration or script. For example:\n  ```sql\n  -- Set last_login_at to current timestamp for all existing students\n  UPDATE students SET last_login_at = CURRENT_TIMESTAMP WHERE last_login_at IS NULL;\n  ```\n- Ensure that any application logic that interacts with the `students` table is updated to handle the new column appropriately.\n\nThis approach adheres to our shared database rules and ensures that the migration is safe and reversible.\n\n---\n**Discipline Gate:**\n- [info] Code in this answer was not verified (tsc/tests unavailable here) \u2014 treat as unchecked.\n- Confidence: **MEDIUM**",

According to the audit findings, specifically C2 and the recurring pattern hit for `env_fallback_disables_security`, you should never fall back to an empty string or default value for security-critical environment variables like `STRIPE_SECRET`.\n\n### Suggested Change\nInstead of falling back to an empty string, your code should reject the request if the secret is missing. This aligns with the organizational belief that security-critical env vars must never fall back to empty or default values.\n\n#### What it changes:\n- The code will now fail loudly when `STRIPE_SECRET` is not set.\n- It ensures that signature verification cannot be bypassed due to a missing environment variable.\n\n#### What it could break:\n- Any existing deployments where the `STRIPE_SECRET` might not be set will start rejecting requests at this endpoint. This could cause issues if there are environments (e.g., development) where the secret is intentionally left unset.\n\n#### What tests verify it:\n- You should add a test case to ensure that the request is rejected when `STRIPE_SECRET` is not set.\n- Ensure that your CI/CD pipeline includes tests for this scenario, especially in environments where the secret might be omitted.\n\n### Example Code\n```javascript\nconst secret = process.env.STRIPE_SECRET;\nif (!secret) {\n  console.error('STRIPE_SECRET environment variable is missing. Refusing to start webhook processing.');\n  return res.status(500).send('Internal Server Error: STRIPE_SECRET is not set');\n}\n\n// Proceed with signature verification and other logic\n```\n\n### Security Consideration\nThis touches authentication. Review with security before merging.\n\nBy making this change, you ensure that the system remains secure even if environment variables are misconfigured or missing.\n\n---\n**Discipline Gate:**\n- [WARN] This touches authentication.

      "response": "Implementing a gem transfer by debiting the sender and crediting the receiver in separate queries can lead to issues if something goes wrong between these two operations. This is an example of the \"transaction gap\" pattern (H3) mentioned in your organizational beliefs.\n\n### What it changes:\n- You're performing two independent database operations: one to debit the sender's gems and another to credit the receiver's gems.\n\n### What it could break:\n- If the system crashes or fails between debiting the sender and crediting the receiver, the sender will have their gems deducted without the receiver receiving them. This results in a permanent loss of currency within your system.\n- It can also lead to inconsistent states where one user's balance is incorrect while the other's is not updated.\n\n### What tests verify it:\n- You should have integration tests that simulate failures between these two operations and ensure that the system recovers correctly or maintains consistency.\n- Unit tests for each operation (debit and credit) are necessary, but they won't catch the gap issue on their own.\n\n### Suggestion:\nTo avoid this issue, you should wrap both operations in a single database transaction. This ensures that either both operations succeed together or neither happens at all, maintaining data integrity.\n\nHere's an example of how you might implement this using `pg` (PostgreSQL client for Node.js):\n\n```javascript\nconst { Pool } = require('pg');\nconst pool = new Pool();\n\nasync function transferGems(senderId, receiverId, amount) {\n  const client = await pool.connect();\n  try {\n    await client.query('BEGIN');\n\n    // Debit sender\n    await client.query(\n      'UPDATE users SET gem_balance = gem_balance - $1 WHERE id = $2',\n      [amount, senderId]\n    );\n\n    // Credit receiver\n    await client.query(\n      'UPDATE users SET gem_balance = gem_balance + $1 WHERE id = $2',\n      [amount, receiverId]\n    );\n\n    await client.query('COMMIT');\n  } catch (err) {\n    await client.query('",

Given the tech stack and the components mentioned, let's break down where this data might be stored.\n\n### Architecture Reasoning\n\n1. **Database (PostgreSQL)**: This is likely where the core data about students and their balances would reside. There could be a table specifically for student information that includes a column for gem balance or a related table that tracks transactions and balances.\n   \n2. **Backend Services**: The Node.js/Express backend would handle fetching this data from the database and serving it to the frontend via API endpoints.\n\n3. **Frontend Stores (Zustand)**: Since you mentioned Zustand with 49 stores, one of these might be responsible for managing the state related to student balances or lecture viewer data. It could be a store that fetches and holds the gem balance for the currently logged-in student.\n\n### Steps to Identify the Store\n\n1. **Database Tables**: Check the PostgreSQL database schema (tables) to see if there's a table dedicated to student balances or transactions. This would involve looking at the migrations or directly querying the database if you have access.\n   \n2. **Backend API Endpoints**: Look for API endpoints in your Express server that fetch data related to students and their gem balances. These endpoints might be used by the frontend to retrieve the necessary information.\n\n3. **Frontend Stores (Zustand)**: Review the Zustand stores to identify which one is responsible for managing the state of the lecture viewer or student-specific data. This store would likely have actions that fetch data from the backend and update its state accordingly.\n\n### Suggestion\n\nGiven that you haven't provided specific source code, I suggest starting with the database schema to understand how student balances are stored.

This involves creating a function that will be executed by `pg-boss` to handle the cleanup logic.\n\n**What it changes:** Adds a new background job definition.\n**What it could break:** If not implemented correctly, this could lead to sessions being deleted prematurely or not at all.\n**Tests verify it:** Unit tests for the session expiration logic and integration tests to ensure the job is scheduled and executed as expected.\n\n```typescript\n// src/jobs/cleanupExpiredSessions.ts\n\nimport { Job } from 'pg-boss';\n\nexport default async function cleanupExpiredSessions(job: Job) {\n  const { db } = job.data;\n\n  try {\n    // Assuming sessions have an `expires_at` column of type TIMESTAMP\n    const now = new Date();\n    await db.query('DELETE FROM sessions WHERE expires_at < $1', [now]);\n    console.log(`Cleaned up expired sessions at ${now.toISOString()}`);\n  } catch (error) {\n    console.error('Failed to clean up expired sessions:', error);\n    throw error;\n  }\n}\n```\n\n### Step 2: Schedule the Job\n\nNext, schedule this job to run every hour. You can do this by adding a configuration in your `pg-boss` setup.\n\n**What it changes:** Schedules a new recurring background job.\n**What it could break:** If not scheduled correctly, the job might not run as expected or could run too frequently.\n**Tests verify it:** Integration tests to ensure the job is scheduled and runs at the correct interval.\n\n```typescript\n// src/pgBossSetup.ts\n\nimport PgBoss from 'pg-boss';\nimport cleanupExpiredSessions from './jobs/cleanupExpiredSessions';\n\nexport async function setupPgBoss(dbConfig: any) {\n  const boss = new PgBoss(dbConfig);\n\n  await boss.start();\n\n  // Register the job handler\n  await boss.work('cleanup-expired-sessions', { batchSize: 1 }, clean",

You can use middleware like `verifyToken` to ensure that only authenticated users can access this endpoint.\n\n### Implementation Example:\nIf you decide to make it an authenticated endpoint, here\u2019s how you could implement it:\n\n```typescript\n// Import necessary modules and functions\nimport express from 'express';\nimport { verifyToken } from './authMiddleware'; // Assuming verifyToken is a middleware function that checks the token\n\nconst router = express.Router();\n\n// Define the route with authentication middleware\nrouter.get('/api/stats/active-students', verifyToken, async (req, res) => {\n    try {\n        const activeStudentCount = await getActiveStudentCount(); // Function to fetch the count of active students from the database\n        res.json({ count: activeStudentCount });\n    } catch (error) {\n        console.error('Error fetching active student count:', error);\n        res.status(500).json({ message: 'Internal server error' });\n    }\n});\n\n// ",

The `role` should be a non-sensitive identifier (e.g., \"student\", \"admin\").\n- **Revocation**: If roles change frequently, updating the JWT requires reissuing it, which can complicate session management.\n\n### Tests to Verify:\n1. **JWT Payload Verification**: Ensure that the new claim is correctly added to the token during authentication.\n2. **Access Control**: Validate that middleware checks using the role from the JWT work as expected.\n3. **Token Size and Performance**: Measure the impact on token size and performance, especially if the JWT is used frequently.\n\n### Security Considerations:\n- **Role Management**: Ensure that roles are managed securely and that changes to roles are reflected in the JWT appropriately (e.g., reissue tokens when roles change).\n- **JWT Expiry**: Consider how often roles might change and whether the token expiry should be adjusted accordingly.\n- **Token Signature**: Verify that the token is signed with a strong secret and that signature verification is enforced.\n\n### Example Implementation:\nHere's a simplified example of how you might add the role to the JWT payload:\n\n```typescript\n// server/src/middleware/auth.ts\n\nimport jwt from 'jsonwebtoken';\nimport { JWT_SECRET } from '../config';\n\nexport function generateToken(user: User): string {\n  const",

However, based on common considerations and architectural beliefs, here are some potential reasons:\n\n1. **Shared Database Instance**: Since staging and production share a PostgreSQL instance, using a queue system that natively integrates with PostgreSQL (like `pg-boss`) can be advantageous. It avoids the need for an additional database or service, simplifying deployment and maintenance.\n\n2. **Additive Migrations**: `pg-boss` being tightly integrated with PostgreSQL means that any necessary schema changes for job management can be done in a way that aligns with your additive migration policy. This ensures that migrations are backward-compatible and reversible, which is crucial when staging and production share the same database.\n\n3. **Security-Centric Design**: If there were specific security requirements or concerns related to how jobs are managed and stored, `pg-boss` might have been chosen for its features around security and data integrity within PostgreSQL.\n\n4. **Community and Support**: The choice could also be influenced by community support, documentation quality, and the ease of troubleshooting issues with a tool that is well-supported within the PostgreSQL ecosystem.\n\n5. **Cost Considerations**: Using `pg-boss` might have been more cost-effective in terms of infrastructure since it leverages an existing database rather than requiring additional resources for another queue system like Redis (which BullMQ uses).\n\n6. **Feature Set and Requirements**: The specific features required by your application's job management needs could have aligned better with what `pg-boss` offers compared to BullMQ.\n\nWithout more detailed information about the decision-making process, these are speculative reasons based on common factors that influence such choices.

This includes handling edge cases and error scenarios.\n- Write unit tests for the logic that interacts with the mocked database to ensure that the business logic is correct.\n- Consider writing integration tests that use a lightweight in-memory database (like SQLite) if you need to test more complex interactions.\n\n### Steps to Implement Mocks\n\n1. **Identify the Database Interactions:**  \n   Determine which parts of your code interact with the database and identify the functions or services that these interactions rely on.\n\n2. **Create Mocks for These Functions/Services:**  \n   Use a mocking library like `jest-mock` (if you're using Jest) to create mock implementations of the identified functions/services.\n\n3. **Update Your Tests to Use the Mocks:**  \n   Modify your test setup to use these mocks instead of the real database interactions.\n\n4. **Validate the Mocks:**  \n   Ensure that the mocks behave as expected and cover all necessary scenarios, including edge cases and error handling.\n\n5.

For now, we assume uniform usage.\n**Tests verify it**: Ensure that tests cover the new utility function for both success and error cases.\n\n#### Step 2: Use the Utility Function\n\nNow, replace the duplicated code in each component with a call to `fetchStudents`.\n\n```typescript\n// src/components/StudentList.tsx\nimport { fetchStudents } from '../utils/apiUtils';\n\nconst StudentList = async () => {\n    const students = await fetchStudents();\n    // Render students...\n};\n\nexport default StudentList;\n```\n\n```typescript\n// src/components/Stude",

Let's review the provided diff and consider its implications.\n\n### What It Changes:\nThe function `removeInactiveStudents` iterates over an array of `Student` objects and removes any student who is not active (`isActive` is false).\n\n### Potential Breaks:\n1. **Index Management**: The use of `splice` inside a loop can lead to issues with index management. When you remove an element from the array, the indices of subsequent elements are shifted down by one. This means that after removing an element, the next iteration will skip over the next student in the list because `i` is incremented regardless of whether an element was removed.\n\n### Tests:\nTo verify this function, we should have tests that cover:\n1. **No Inactive Students**: The array remains unchanged.\n2. **All Inactive Students**: The array becomes empty.\n3. **Mixed Active and Inactive Students**: Only active students are retained in the correct order.\n4. **Edge Cases**: Empty array input.\n\n### Suggested Fix:\nTo avoid skipping elements, we can iterate backwards or use a filter method which is more idiomatic for this kind of operation:\n\n#### Iterating Backwards:\n```typescript\nfunction removeInactiveStudents(students: Student[]): Student[] {\n  for (let i = students.length - 1; i >= 0; i--) {\n    if (!students[i].isActive) {\n      students.splice(i, 1);\n    }\n  }\n  return students;\n}\n```\n\n#### Using Filter:\n```typescript\nfunction removeInactiveStudents(students: Student[]): Student[] {\n  return students.filter(student => student.isActive);\n}\n```\n\n### Security and Audit Findings:\n- **No Auth Changes**: This function does not touch authentication.\n- **No Known Audit Findings**: The code snippet provided doesn't seem to relate directly to any of the known audit findings listed.\n\n### Conclusion:\nThe original implementation has a bug related to index management. Using `filter` is generally more readable and avoids this issue. If you prefer to stick with modifying the array in place, iterating backwards is a sa",

This means that the effect will only run once when the component mounts, and it will always log the initial value of `count` (which is 0) because it closes over the initial value of `count`.\n\n### What it changes:\n- The interval function inside `useEffect` will always use the initial value of `count` due to closure capturing.\n\n### What it could break:\n- The intended behavior of logging and updating `count` every second won't work as expected. Instead, it will log \"Current count: 0\" repeatedly.\n\n### What tests verify it:\n- Unit tests that check the behavior of the component over time, especially those involving state updates and side effects.\n- Manual testing by observing the console output to ensure it increments correctly.\n\n### Suggested fix:\nTo fix this, you should include `count` in the dependency array. However, directly using `count` inside `setCount(count + 1)` can lead to stale closures as well. Instead, use a functional update:\n\n```typescript\nconst [count, setCount] = useState(0);\nuseEffect(() => {\n  const interval = setInterval(() => {\n    console.log('Current count:', count);\n    setCount(prevCount => prevCount + 1); // Use functional update to avoid closure issues\n  }, 1000);\n  return () => clearInterval(interval);\n}, [count]); // Include count in the dependency array\n```\n\nThis ensures that `setCount` always receives the most recent state value, and the effect re-runs whenever `count` changes.\n\n---\n**Discipline Gate:**\n- [info] Code in this answer was not verified (tsc/tests unavailable here) \u2014 treat as unchecked.\n- Confidence: **MEDIUM**",

If it's empty or not set, the application should terminate with an error message.\n\n#### What It Changes:\n- The application will now explicitly check for the `JWT_SECRET` environment variable during startup.\n- If `JWT_SECRET` is missing or a placeholder (like \"default\" or \"\"), the application will call `process.exit(1)` to terminate immediately.\n\n#### What It Could Break:\n- This change could break deployments where the `JWT_SECRET` env var is not set correctly. However, this is intentional as it ensures that the application does not run with an insecure configuration.\n- If developers forget to set the environment variable locally, they will need to do so before starting the application.\n\n#### What Tests Verify It:\n- Unit tests should be added to verify that the application exits when `JWT_SECRET` is missing or invalid.\n- Integration tests can simulate a deployment scenario where the env var is not set and ensure that the application does not start.\n\n### Example Code Snippet:\n```javascript\nconst jwtSecret = process.env.JWT_SECRET;\n\nif (!jwtSecret || jwtSecret === \"default\" || jwtSecret.length < 32) {\n    console.error(\"JWT_SECRET must be set to a secure value. Exiting...\");\n    process.exit(1);\n}\n```\n\nThis approach ensures that we fail closed on security, as per our organizational beliefs.\n\n---\n**Discipline Gate:**\n- [WARN] This touches authentication.

This approach should be avoided at all costs, especially when dealing with sensitive operations like grading.\n\nInstead, consider using a safer alternative for evaluating mathematical expressions. One common approach is to use a library that parses and evaluates mathematical expressions securely. Libraries like `mathjs` are designed for this purpose and can handle complex formulas without the security risks associated with `eval()`.\n\nHere\u2019s how you might implement such a handler using `mathjs`:\n\n1. **Install mathjs**: First, add the `mathjs` library to your project.\n   ```bash\n   npm install mathjs\n   ```\n\n2. **Create the handler**: Implement the handler that uses `mathjs` to evaluate the formula.\n\n```typescript\nimport { Request, Response } from 'express';\nimport * as math from 'mathjs';\n\n// Ensure you sanitize and validate inputs before using them.\nconst evaluateFormula = (req: Request, res: Response) => {\n    const { formula, variables } = req.body;\n\n    // Validate that the input is a string\n    if (typeof formula !== 'string') {\n        return res.status(400).json({ error: 'Invalid formula' });\n    }\n\n    try {\n        // Evaluate the formula with provided variables\n        const result = math.evaluate(formula, variables);\n        res.json({ result });\n    } catch (error) {\n        console.error('Error evaluating formula:', error);\n        res.status(400).json({ error: 'Invalid formula or variables' });\n    }\n};\n\nexport default evaluateFormula;\n```\n\n### What it changes:\n- Replaces `eval()` with a safe library (`mathjs`) for evaluating mathematical expressions.\n- Adds basic input validation to ensure the formula is a string.\n\n### What it could break:\n- If the `variables` object contains malicious data, it might still pose security risks. Ensure that all inputs are sanitized and validated thoroughly.\n- The handler",

Here's how you can modify your code:\n\n```typescript\nconst secret = process.env.GITHUB_WEBHOOK_SECRET;\nif (!secret) {\n  // No secret configured, reject all webhooks\n  return res.status(401).send('Unauthorized: Missing GITHUB_WEBHOOK_SECRET');\n}\n\n// Proceed with signature verification using the secret\n```\n\n### What it changes:\n- The code now explicitly checks if `GITHUB_WEBHOOK_SECRET` is undefined or empty.\n- If the secret is missing, it responds with a 401 Unauthorized status and an appropriate message.\n\n### What it could break:\n- Any existing GitHub webhooks that rely on the system accepting requests without a secret will fail. This might disrupt any automated processes that depend on these webhooks.\n\n### What tests verify it:\n- Unit tests should be added to ensure that the endpoint returns a 401 status when `GITHUB_WEBHOOK_SECRET` is not set.\n- Integration tests should verify that valid signed webhooks are accepted and invalid ones (including those without a secret) are rejected.\n\n### Security Callout:\nThis touches authentication. Review with security before merging.\n\nBy making this change, you ensure that your system remains secure even if the environment variable is not properly configured, adhering to the principle of failing closed on security.\n\n---\n**Discipline Ga",

Specifically, you're touching on the audit finding related to \"Agent job payments without transaction.\"\n\n### Issue:\n- **Transaction Gap (H3)**: You are performing two separate operations (updating the student's balance and creating a ledger entry) that should be atomic. If the second operation fails, the first one will have already committed, leading to an inconsistent state where the balance is updated but there's no record of the transaction.\n\n### Suggestion:\nTo ensure data integrity, both operations should be part of a single database transaction. This way, either both operations succeed or neither does, maintaining consistency in your data.\n\n#### What it changes:\n- Wraps the balance update and ledger entry creation within a single database transaction.\n\n#### What it could break:\n- If there's any logic that assumes these operations are independent (e.g., logging or other side effects), those parts might need to be adjusted.\n- Ensure that all error handling is done within the transaction block to properly roll back changes in case of failure.\n\n#### What tests verify it:\n- Unit tests should cover scenarios where both operations succeed and fail, ensuring the transaction behaves as expected.\n- Integration tests should simulate real-world conditions, including network failures or other issues that could cause one operation to fail while the other succeeds.\n\n### Example Code (Pseudo-code):\n```typescript\nasync function processJobPayment(studentId: string, amount: number): Promise<void> {\n  const client = await pool.connect();\n  try {\n    await client.query('BEGIN');\n\n    // Update student balance\n    await client.query(\n      'UPDATE students SET gem_balance = gem_balance + $1 WHERE id = $2',\n      [amount, studentId]\n    );\n\n    // Create ledger entry\n    await client.query(\n      'INSERT INTO ledger (stude",

      "response": "Based on the architecture and known audit findings, I can reason that line 48 of `server/src/services/lectureCapture.ts` is likely related to a critical issue involving an ID type mismatch. Specifically, audit_finding_C1 describes a problem where `socket.userId` (a numeric string) is being compared to `lecture_sessions.instructor_id` (a UUID column), which can cause all lectures to break.\n\nGiven this context, line 48 is probably performing a comparison or assignment that assumes both IDs are of the same type. This mismatch would lead to incorrect behavior because JavaScript's strict equality (`===`) operator will always return false when comparing a string and a UUID object.\n\nTo address this issue, you should ensure that the types are consistent before making any comparisons. For example, you could convert `socket.userId` to a UUID format or vice versa.\n\nHere\u2019s a suggested change:\n\n```typescript\n// Assuming socket.userId is a numeric string and needs conversion to UUID\nconst instructorId = uuidFromString(socket.userId); // Hypothetical function to convert string to UUID\n\nif (lectureSession.instructor_id === instructorId) {\n    // Proceed with the logic\n}\n```\n\n**What it changes:** Ensures that `socket.userId` is converted to a UUID before comparison, fixing the type mismatch.\n\n**What it could break:** If there are other parts of the codebase expecting `socket.userId` to remain a string, this change might cause issues. Ensure all related areas handle the ID correctly after conversion.\n\n**Tests verify it:** Unit tests for lecture capture functionality should cover scenarios where instructor IDs match and do not match, ensuring that the conversion does not introduce regressions or new bugs.\n\n---\n**Discipline Gate:**\n- [WARN] Draft walks into audit finding C1 (Lecture instructor_id type mismatch \u2014 all lectures broken). socket.userId is a numeric string but lecture_sessions.instructor_id is a UUID column.

If `rejectIfIneligible` runs before `verifyToken`, it might reject requests from users without properly verifying their identity.\n2. **Security**: This change could introduce security vulnerabilities if `rejectIfIneligible` relies on information that is only available after the token has been verified.\n\n### Tests to Verify:\n- Ensure that all routes still correctly authenticate and authorize users.\n- Test scenarios where a user is ineligible but has a valid token, and vice versa.\n- Verify that the middleware chain behaves as expected in both development and production environments.\n\n### Alternative Approach:\nInstead of changing the order, you could enhance `verifyToken` to include some preliminary checks for eligibility. This way, you maintain the current security flow while adding additional logic where needed.\n\n### Example Code Suggestion (Hypothetical):\nIf you decide to proceed with reordering, here\u2019s how you might do it:\n\n```javascript\napp.use(rejectIfIneligible);\napp.use(verifyToken);\n```\n\nHowever, this approach should be carefully considered and tested due to the potential issues mentioned above.\n\n### Security Flag:\nThis touches authentication.
