From 46b46479caeccc471ef3c648c636e2afa0c2959b Mon Sep 17 00:00:00 2001 From: Praxis CI Date: Tue, 4 Aug 2026 01:00:11 +0000 Subject: [PATCH] =?UTF-8?q?feat(P01):=20SLICE-06=20P1=20integration=20?= =?UTF-8?q?=E2=80=94=20wire=20lifespan=20+=20auth=20+=20verification=20swa?= =?UTF-8?q?p?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - 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 - TASK-06-03 __main__.py: /vc/verify swapped to the two-store path (G-011): pg_store for key lookup (active + superseded), SQLite fallback for v0.3 credentials, SQLite-only if no Postgres.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5 e2e tests (skip if no Postgres) — R-VC-MIG-01 critical (v0.3 VC verifies against archived superseded key in Postgres), idempotent migration, G-027 first-boot, v0.04 VC verifies, tamper detection.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). ---ci--- project: praxis phase: 1 milestone: v0.4 status: execute persona: backend-engineer task: 06-01,06-02,06-03,06-04,06-05 requirements: covered: [REQ-MT-01, REQ-AUTH-01, REQ-NFR-AUTH-01, REQ-NFR-MT-01] grill: - G-011 (two-store fallback wired in /vc/verify) risks: - R-VC-MIG-01 (e2e test: v0.3 VC verifies against archived superseded key in Postgres) ---/ci--- --- server/__main__.py | 73 ++++++++++- tests/test_p1_auth_integration.py | 115 ++++++++++++++++ tests/test_p1_vc_migration_e2e.py | 209 ++++++++++++++++++++++++++++++ 3 files changed, 390 insertions(+), 7 deletions(-) create mode 100644 tests/test_p1_auth_integration.py create mode 100644 tests/test_p1_vc_migration_e2e.py diff --git a/server/__main__.py b/server/__main__.py index ae0a2d9..61b00ff 100644 --- a/server/__main__.py +++ b/server/__main__.py @@ -28,16 +28,25 @@ try: except ImportError: # pragma: no cover pass -from fastapi import FastAPI, HTTPException +from fastapi import FastAPI, HTTPException, Request from fastapi.middleware.cors import CORSMiddleware +from fastapi.responses import JSONResponse from fastapi.staticfiles import StaticFiles from pipecat.transports.smallwebrtc.connection import SmallWebRTCConnection +from slowapi.errors import RateLimitExceeded +from slowapi import _rate_limit_exceeded_handler from db.pg_migrate import apply_pg_migrations from db.pg_store import PgStore from db.store import PraxisStore +from server.auth.cookies import get_session_middleware_kwargs +from server.auth.rate_limit import limiter +from server.auth.routes import router as auth_router from server.pipeline import build_pipeline +from server.vc.issuer_keys import _load_root_key +from server.vc.migrate_keys import migrate_issuer_keys from server.vc.verification import verify_credential +from starlette.middleware.sessions import SessionMiddleware _store = PraxisStore() @@ -89,6 +98,10 @@ async def lifespan(app: FastAPI): logger.info(f"Postgres migrations applied: {applied}") else: logger.info("Postgres migrations up to date") + # VC key migration (TASK-06-03, R-VC-MIG-01, G-027) — runs once on + # first boot, idempotent.
