Praxis CI
00e39a3f85
Phase 1 complete — Operator Foundation: - Postgres 16 in Docker-in-LXC (asyncpg pool, 5-table schema, PgStore, migrations) - Operator auth (argon2id, signed stateless cookies, slowapi 5/min rate limit) - VC issuer key migration SQLite→Postgres (archive-before-active, R-VC-MIG-01) - Operator bootstrap CLI (create-operator.py, idempotent) - Backup cron script + G-008 restore drill - Graceful degradation (server starts without Postgres) - 272 tests pass, 33 skip (Postgres-requiring), 0 fail ---ci--- project: praxis phase: 1 milestone: v0.4 status: complete requirements: covered: [REQ-MT-01, REQ-AUTH-01, REQ-NFR-AUTH-01, REQ-NFR-MT-01, REQ-MT-02] partial: [] ---/ci---
