Praxis CI 46b46479ca feat(P01): SLICE-06 P1 integration — wire lifespan + auth + verification swap
- TASK-06-01 __main__.py: SessionMiddleware (signed cookies, D-056) added
  AFTER CORS so it is outermost. slowapi limiter state + 429 exception
  handler registered. The lifespan (TASK-01-03) now also runs the VC key
  migration on first boot.
- TASK-06-02 __main__.py: auth_router mounted (POST /api/operator/login,
  POST /api/operator/logout, GET /api/operator/me) BEFORE the StaticFiles
  mount (routes-before-static constraint). Auth routes use app.state.pg_store
  (503 if no Postgres).
- TASK-06-03 __main__.py: /vc/verify swapped to the two-store path (G-011):
  pg_store for key lookup (active + superseded), SQLite fallback for v0.3
  credentials, SQLite-only if no Postgres. _maybe_migrate_issuer_keys()
  runs once in the lifespan (idempotent, G-027 first-boot, non-fatal on
  failure — v0.3 path intact).
- TASK-06-04 tests/test_p1_auth_integration.py: 4 e2e tests (skip if no
  Postgres) — full auth flow, /me without cookie 401, wrong password 401,
  learner voice loop unaffected (REQ-NFR-MT-01).
- TASK-06-05 tests/test_p1_vc_migration_e2e.py: 5 e2e tests (skip if no
  Postgres) — R-VC-MIG-01 critical (v0.3 VC verifies against archived
  superseded key in Postgres), idempotent migration, G-027 first-boot,
  v0.04 VC verifies, tamper detection.

Graceful degradation verified: server starts without Postgres (pg_pool/
pg_store are None; voice loop works; auth routes return 503).

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

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.
