# Sprint 0 — Mimic

Repo skeleton + foundational modules. Nothing that depends on PR1/PR2/PR3.

## Backend (`backend`)

- [ ] B0.1 — `backend/` Python project: `pyproject.toml` (ruff, mypy strict, pytest, coverage),
      `Makefile`, `Dockerfile`, `docker-compose.yml` for Postgres dev DB.
- [ ] B0.2 — Alembic init + complete initial migration covering the §8 schema (incl.
      `c2_credential`, `user`, `group`, `user_group`, `permission`, `group_permission`,
      `soc_session`, audit_log with write-only Postgres role). **No `ttp_version` table** (D-009).
      Seed groups `rt_operator`, `rt_lead`, `soc_analyst` with F11 permissions (D-008).
- [ ] B0.3 — SQLAlchemy 2 typed mapped classes for every table + repositories scaffold.
- [ ] B0.4 — `C2Connector` ABC + dataclasses (`Payload`, `TaskHandle`, `TaskResult`) + enum
      `payload_type` + factory keyed on `c2_type`. **No real implementation.**
- [ ] B0.5 — Jinja2 SandboxedEnvironment + `regex_extract` filter via `google-re2` +
      `{{outputs.text}}` and `{{outputs.blob(key)}}` accessors with 10 MB cap.
- [ ] B0.6 — Local auth (login/password bcrypt + Flask server-side sessions) + RBAC
      group-based decorators + F11 permission matrix declared in code.
- [ ] B0.7 — Flat CRUD endpoints (engagements, hosts, TTPs, scenarios) — no orchestration,
      no WebSocket, no reporting yet.
- [ ] B0.8 — pytest baseline: unit (SQLite) + integration scaffold (testcontainers Postgres).

## Frontend (`ux-frontend`)

- [x] F0.1 — `frontend/` Vite + React + TypeScript strict + Tailwind 4 + TanStack Query 5,
      eslint strict + prettier, Playwright skeleton.
- [x] F0.2 — Design system provisional: semantic tokens in `theme.css` (status colors, RT accent,
      data mono / UI sans), dark-first palette, placeholder logo.
- [x] F0.3 — Wireframes (via `frontend-design` skill) on mock data:
      Login + engagement selection, Live cockpit, Scenario composer,
      Report + MITRE matrix, TTP library + import.
- [x] F0.4 — Routing skeleton + role-aware layout shell (no real auth wired yet).
- [x] F0.5 — Push `feature/frontend-skeleton`, open PR for code-reviewer.
- [x] F0.6 — Polish M1-M3 from code-review (single SessionProvider, typo, fallback removal).

### Frontend follow-ups (sprint 1+, non-blocking, from review NITs)

- [ ] N1 — Tighten `readMockSession` payload validation when real auth wires up
      (currently checks only `role`; should validate the full `SessionUser` shape).
- [ ] N2 — Replace the UI-side recomposition of the `MIMIC-RUN:` marker in the
      cockpit's "Resolved command" panel with `resolvedCommandText` returned by
      the backend (`run_step_cleanup.resolved_command_text` for cleanup, equivalent
      field for steps when exposed).
- [ ] N3 — Wire `StatusRail.linkState` to the real WebSocket connection state once
      Flask-SocketIO is reachable (currently hardcoded `'up'`).
- [x] N4 — Unify `router.tsx` and any future router helpers under `src/routing/`
      (single naming, no split between root file and folder). _Addressed in F0.6:
      `src/routing/Root.tsx` introduced; `router.tsx` left at top level as the
      app-level entry that other code imports — split kept minimal._
- [ ] N5 — Actually import Recharts somewhere (likely the MITRE matrix or a latency
      chart) since it's declared in README + package.json but not yet used.
- [ ] N6 — When vendoring IBM Plex woff2 into `public/fonts/`, add
      `public/fonts/LICENSE.txt` (OFL-1.1) for license compliance.
- [ ] N7 — Add `frontend/.env.example` exposing `VITE_API_BASE_URL` and
      `VITE_WS_URL` once the backend publishes endpoints.

## Spec / Docs (`spec-analyst`)

- [ ] S0.1 — Cross-check the data model in B0.2 against §8 of the spec; report deltas before merge.
- [ ] S0.2 — Cross-check the RBAC matrix in B0.6 against F11; report deltas before merge.
- [ ] S0.3 — Maintain `tasks/spec-decisions.md` as new arbitrations land.
- [ ] S0.4 — Open `docs/architecture.md` once backend layout is committed.

## Review (`code-reviewer`)

- [ ] R0.1 — Review each PR per the published charter; block on security/OPSEC violations.
- [ ] R0.2 — Verify mypy strict and ruff clean before approving any backend PR.
- [ ] R0.3 — Verify TS strict, no `useEffect(fetch)`, exhaustive deps before approving any frontend PR.
