Standalone, any order:
- Guided build: the chatbot, line by line
- Personality/cost/memory-cap
- Add a stats command
- Add a clear command
- Cap message length
- Log the conversation to a file
- Classify a message
- Retry with backoff
- Switch models mid-conversation
The guided build is required before the project; 01-08 are optional practice reps, each a self-contained tweak to the same chatbot.
