Project description:
"Coding Test - INVITE ONLY - OTHERS DO NOT BID

This is a PAID test (fixed at $10) for all shortlisted candidates who have applied for 'Full-Stack Developer for AI Companion App ([login to view URL], Node.js, GPT, Voice & Payments)'

The test evaluates your ability to work with [login to view URL], handle chat + memory + payment logic, and write clean, modular code.

Scope of the Test

Duration: 1 hour
Language: JavaScript / TypeScript (Node + [login to view URL])

Task: Implement a mini chat API route that includes:
1. Persona-based AI responses (mock AI responses, no real API call required)
2. Short-term memory for each user (store last 5 messages)
3. Wallet/credit deduction logic (5 credits per message)
4. Optional bonus: persona override & simulated async AI call

You will be provided with:
1. Mock user object (pre-defined user account)
2. Mock memory store (simulated backend memory for chat)

No real database or API keys are required — everything runs in memory for the test.

Deliverables
1. pages/api/[login to view URL] (or JS equivalent) with working logic
2. Helper functions for memory management, payment checks, and mock AI responses
3. Example POST request + response demonstrating functionality
4. Short explanation of how memory, persona, and payment logic work together

Evaluation Criteria
1. Correct handling of short-term memory (max 5 messages)
2. Proper persona handling and API response
3. Correct wallet/credit deduction
4. Clean, modular, readable code
5. Handling of edge cases (insufficient balance, memory overflow, unknown persona)
6. Bonus: async handling & persona override

Test opens at 2.30pm UTC and closes at 3.30pm UTC. Starter files to be provided before the test begins.

You may choose not take the test in which case your application will not proceed to the final selection" (client-provided description)
