Summary
Several environment variables are configured in .env files but referenced nowhere in code — leftovers from removed functionality.
Evidence
TREMOR_MODEL_PATH, DRAWING_MODEL_PATH, SPEECH_MODEL_PATH exist in root .env.example and docker/.env.docker, but rg -n "MODEL_PATH" *.py returns nothing. Models load weights by relative path from ml/_FINAL_SCRIPTS/weights (ml/predictor.py).EXPO_ACCESS_TOKEN exists in docker/.env.docker but no code references it — leftover from the deleted Expo/mobile-event push channel.
Suggested fix
Remove the unused keys from .env.example, docker/.env.example, and the local docker/.env.docker (never commit .env.docker values — it's gitignored). Keep the removal out of .env.docker's committed copy only if something external (deploy env on the Oracle VM) still sets them.
