Unit: - test_auth_schemas: LoginRequest validation (min/max bounds, extra-fields policy) + serialize_current_user round-trip (RT lead permission set, RT operator subset, display_name None pass-through). Integration (testcontainers Postgres, marked `integration`): - test_login_then_create_and_list_engagement: full sprint-1 user journey — /me → 401, POST /login → 200, /me → 200, POST /engagements → 201, GET /engagements lists the new row, POST /logout → 204, /me → 401. - test_login_rejects_bad_credentials: wrong password AND unknown user return the exact same 401 invalid_credentials envelope (no enumeration leak). - test_logout_without_session_returns_401: /logout on anonymous returns the uniform not_authenticated envelope. Unit total: 61 passed in 0.50s. Integration tests skip locally when testcontainers is absent.

Local dev
make install # uv venv + pip install -e .[dev]
make db-up # $(CONTAINER) compose up -d postgres (auto-detect docker|podman)
make db-bootstrap # one-time: create the mimic_audit_writer role (see below)
make db-migrate # alembic upgrade head
make run # flask run (debug)
make test # pytest unit
make test-int # pytest integration (testcontainers)
make lint # ruff + mypy strict
Audit writer role (dev)
mimic_audit_writer is provisioned by the Ansible playbook in production
(decision D-010). For local development, create it manually after make db-up:
# Substitute "podman" for "docker" if your runtime is Podman.
$(command -v docker || command -v podman) exec -it mimic-postgres \
psql -U mimic_app -d mimic \
-c "CREATE ROLE mimic_audit_writer LOGIN PASSWORD 'pick-a-dev-secret';"
Then expose the same secret in MIMIC_DATABASE_AUDIT_URL in your .env. The
Alembic migration grants the INSERT-only permission on audit_log against
this role; if it does not exist, the grant block is a no-op (idempotent).
What sprint 0 ships
- Full §8 data model + Alembic initial migration (Postgres-specific constraints: audit_log write-only role, soc_session hash, c2_credential Fernet column).
C2ConnectorABC + dataclasses +payload_typeenum + factory. No real Mythic/Home implementation (blocked on PR1/PR2).- Jinja2 SandboxedEnvironment +
regex_extractfilter (re2). - Local auth (bcrypt + Flask session) + group-based RBAC matching the F11 permission matrix.
- Flat CRUD on engagements / hosts / TTPs / scenarios.
- pytest baseline + testcontainers Postgres scaffolding.
