Pre-merge sanity per devops checklist (ruff format --check, mypy --strict). Type fixes: - ORM models: `Mapped[dict]` → `Mapped[dict[str, Any]]` (audit, scenario, run, report, ttp, detection.artifact_files_json). Equivalent on Pydantic DTOs (TtpBase.params_schema_json, ScenarioStepBase.params_override_json). - Rename `TtpRead.current_version` → `TtpRead.version` to mirror the ORM column (which itself was renamed in D-009 cleanup). - Flask blueprints: add `-> ResponseReturnValue` to every view, plus typed UUID params on `_validate_step_consistency`. - `templating/filters.py`: rewrite the conditional re2 import so mypy can narrow the union (`ModuleType | None`); the runtime branch on `_re2 is not None` removes the unused-ignore that was triggered by warn_unused_ignores. - `pyproject.toml`: add `flask_login.*` and `pythonjsonlogger.*` to the `[[tool.mypy.overrides]]` `ignore_missing_imports` list (both ship without typed marker). - Misc: drop stale `# type: ignore` comments (`app.py:36`, `rbac/decorators.py:35`) flagged by `warn_unused_ignores`. Keep `logging.JsonFormatter` ignore because the symbol exists at runtime but is not re-exported through the typed surface. Formatting: - `ruff format` applied (15 files normalized; line-length unchanged at 100). Verification on this commit: - `ruff check` → All checks passed. - `ruff format --check` → 68 files already formatted. - `mypy --strict src` → Success: no issues found in 54 source files. - `pytest tests/unit` → 49 passed.

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.
