server/, client/, scenarios/, db/, scripts/, tests/, docs/ dirs match PERSONAS.md territory. pyproject.toml declares pipecat-ai[deepgram,cartesia,piper,webrtc] + openai + pydantic + pyyaml + aiosqlite + httpx + websockets. .env.example documents DEEPGRAM_API_KEY, CARTESIA_API_KEY, OLLAMA_API_KEY and the TTS selection (PRAXIS_TTS=cartesia|piper). Verified: python -c 'import pipecat' succeeds (pipecat-ai 1.6.0 installed). ---ci--- phase: 1 milestone: v0.1 plan: 01 task: 01-01 status: execute persona: lead-developer requirements: covered: [REQ-ORCH-01] ---/ci---
Praxis — v0.1 Foundation
Voice-first AI apprenticeship platform. v0.1 is a tech-validation harness (per G-008) for the minimal viable voice loop: a single learner speaks to an AI tutor playing a Customer Service role-play scenario, hears a <600ms-latency response, receives an end-of-session coaching debrief, and has the session logged to SQLite.
Status
Phase 1 (minimal viable voice loop) — code-complete, pending live API keys for runtime verification.

Quickstart
- Copy
.env.example→.env, fill inDEEPGRAM_API_KEY,CARTESIA_API_KEY,OLLAMA_API_KEY. - Install server deps:
pip install -e ".[dev]" - Install client deps:
cd client && npm install - Run probes:
python scripts/probe_deepgram.py(etc.) - Run server:
python -m server - Run client:
cd client && npm run dev
