Three follow-ups on the flat CRUD blueprints triggered by code-review + spec-analyst (MA4, MA5, MA6). **MA4 — `created_by_id`** — engagements, TTPs and scenarios now record the creator from `current_user.id` instead of leaving the FK NULL. The new `api._helpers.current_user_id()` exposes the UUID safely (returns None when the request is unauthenticated, e.g. during /healthz). **MA5 — Audit log integration** — `api._helpers.audit_write(...)` wraps the hash-chained `AuditWriter` and is called after every successful commit in the 4 blueprints (engagement / host / ttp / scenario incl. step), recording the actor, action, resource type/id, IP, user agent, and small metadata (field list, names, engagement scope). F13 "Toute mutation tracée" now holds end-to-end. **MA6 — RT operator scope on engagements** — F11 limits RT operators to "engagements assignés". The previous implementation let them list / read every engagement and every nested resource. Fix: `is_rt_lead()` short- circuits the check for RT leads; otherwise a membership probe against `engagement_member` runs on every list/read and on `_engagement_or_404` in `hosts.py` and `scenarios.py`. Listings now `JOIN engagement_member` and filter by `current_user.id`. `audit_write` casts `db.session` (a `scoped_session` proxy) to the unwrapped `sqlalchemy.orm.Session` that `AuditWriter` expects; the two are interchangeable at runtime. The promotion-perm check on TTPs no longer needs a lazy `flask_login` import since the decorator scope already brings `current_user` in.

Local dev
make install # uv venv + pip install -e .[dev]
make db-up # docker compose up -d postgres
make db-bootstrap # one-time: create the mimic_audit_writer role (see below)

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:
docker 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.
