Praxis CI ec397f2c65 docs(milestone): complete v0.5-live-assist — v0.1.13 tagged, milestone release, merged to main
v0.5 (Live Assist — on-the-job voice companion) milestone complete.
4 phases: P0 (pre-execution, v0.1.10) → P1 (assist core + guardrail,
v0.1.11) → P2 (integration + tech-debt + NFR, v0.1.12) → P3 (final
review + ship, v0.1.13 = milestone release).

16/16 REQs covered (3 ASSIST + 4 NFR + 9 IDEATE). 4 v0.6 backlog.
469 tests passed, 0 failed. 1 P0 fixed (guardrail processor safety).
8 P1+ flagged for v0.6. 8 v0.4 P1+ tech-debt addressed.
G-049 + G-067 grill MUSTs resolved. ESCALATION-01 (PIPEDA) OPEN for
human legal review before assist surface go-live.

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.

Stack

  • Orchestration: Pipecat (D-017) with Silero VAD + interruptibility
  • ASR: Deepgram Nova-3 streaming (D-013)
  • LLM: Ollama Cloud direct API (D-020) — gemma4:cloud (role-play) + deepseek-v4-flash:cloud no-think (debrief)
  • TTS: Cartesia Sonic (primary, D-014) / Piper (self-hosted, R4 mitigation) — behind an interface
  • Client: React + Vite + WebRTC (Pipecat client SDK, D-015)
  • State: SQLite praxis.db (D-007, single hardcoded learner, no auth)

Layout

server/      Pipecat pipeline, services (TTS/LLM/Guardrail interfaces), scenario runtime, adapters
client/      React + Vite + WebRTC learner surface
scenarios/   YAML scenario definitions (D-018)
db/          SQLite schema, migrations, async store
scripts/     Latency probes (R1-R4), e2e smoke
tests/       Unit + e2e
docs/        Latency report, debrief templates

Quickstart

  1. Copy .env.example.env, fill in DEEPGRAM_API_KEY, CARTESIA_API_KEY, OLLAMA_API_KEY.
  2. Install server deps: pip install -e ".[dev]"
  3. Install client deps: cd client && npm install
  4. Run probes: python scripts/probe_deepgram.py (etc.)
  5. Run server: python -m server
  6. Run client: cd client && npm run dev

See docs/latency-report.md for the R1-R4 spike status and TTS decision.
