Engagement members on `/api/v1/engagements/<eid>/members`:
- `GET` lists members (flat array, ordered by `added_at`). Permission
`ENGAGEMENT_READ`.
- `POST` adds a member. Permission `ENGAGEMENT_MEMBER_MANAGE`. Body
`{user_id, role?}`; `role` defaults to `"member"` (D-017). Returns 201
with `EngagementMemberRead`, 404 if the user is disabled/unknown, or
`409 already_member` on duplicate.
- `DELETE /members/<uid>` revokes. 204 on success, 404 if the membership
doesn't exist.
Every route reuses `_engagement_or_404` *before* any membership query, so
an RT operator targeting a foreign engagement receives the same 404 as for
a non-existent ID — matching the MA6 anti-leak posture flagged by
spec-analyst on this sprint.
Audit log viewer on `/api/v1/audit/log`:
- Single endpoint `GET`, paginated `Page[AuditLogEntry]`, gated by
`AUDIT_READ` (rt_lead only).
- Filters: `?action=`, `?actor_id=`, `?resource_type=`, `?since=`,
`?until=`. Times are ISO 8601; invalid input goes through the global 422
envelope with a `loc` field for the bad parameter.
- Exposes `prev_hash` / `row_hash` to support future client-side
chain-verification (D-013 stayed v1).
- Sorted by `ts DESC` so the most recent activity is the first page.
Blueprints registered in `api/__init__.py`.
Mimic
Internal BAS (Breach & Attack Simulation) platform for the Red Team. Replays TTPs from engagement journals or an internal ATT&CK library against client infrastructure through VPN/relay, in white-glove coordination with the SOC.
Output: a coverage report mapped to MITRE ATT&CK — measurable, reproducible, archived.
Status
ready-with-prereqs — spec frozen on 2026-05-19, 23 review patches integrated.
Code start blocked on:
- PR1 — Mythic API documentation + pinned version (lead RT)
- PR2 — Internal C2 interface spec + journal export example (internal C2 team)
- PR3 — RT graphic charter for the PDF report (lead RT)
While PR1/PR2/PR3 are open, sprint 0 focuses on the unblocked skeleton.
Spec
The authoritative spec lives in the RT-SecondBrain vault:
Projects/Mimic — Spec.md. Do not duplicate it here.
In-repo documentation:
CHANGELOG.md— chronological log of features, decisions, rollbacks.tasks/spec-decisions.md— implementation arbitrations on top of the spec.tasks/todo.md— current sprint backlog.
Stack (frozen)
- Backend Python 3.12 / Flask / Flask-SocketIO / SQLAlchemy 2 / Pydantic 2 / Alembic / WeasyPrint / pytest + testcontainers / ruff / mypy strict
- Frontend TypeScript / React 18+ / Vite / Tailwind 4 / TanStack Query 5 / Recharts / Playwright
- Storage Postgres (prod) / SQLite (pure-logic unit tests) / testcontainers Postgres (audit log, RBAC, write-only role — incl. unit tests of Postgres-specific behavior, per H38)
- Deploy Docker images + Ansible deployment playbook (per D-010). Reverse proxy (Caddy + TLS + IP allowlist) handled by existing RT infrastructure, out of Mimic scope (D-007).
