- Flask app factory wires SQLAlchemy / Migrate / Login / SocketIO and
registers every blueprint. /healthz smoke endpoint included.
- Pydantic 2 DTOs (request/response) for engagement / host / TTP /
scenario aggregates with from_attributes=True conversion.
- Flat CRUD blueprints under /api/v1/:
* engagements (list / create / get / put / delete-as-archive)
* hosts (engagement-scoped CRUD)
* library/ttps (CRUD; promote requires the lead-only TTP_PROMOTE)
* scenarios + steps (F3 invariant enforced: host.c2_type must match
scenario.c2_type at compose time, 400 otherwise).
- @require_perm guards every endpoint per the F11 matrix.
- audit/ writer is hash-chained from v1 (SHA-256 of canonical record
plus previous hash). The SQL-level write-only role enforcement ships
in the deploy playbook (idempotent grants run at migration time).
- mimic-cli (click): user create (seeds RT operator/lead with group
membership), db dump / db restore (manual pg_dump/pg_restore, R-O1).
No orchestrator, no WebSocket, no report generation — those land after
PR1/PR2/PR3.
- Permission enum + GroupName enum + GROUP_PERMISSIONS mapping mirror
the F11 matrix in code (verifiable against the spec table in tests).
- @require_perm decorator: 401 on anonymous, 403 on missing permission,
passes through otherwise. Pure-function user_has() for unit-testing.
- AuthUser (Flask-Login wrapper) resolves the permission set from a
User's groups; load_user is the Flask-Login user_loader.
- bcrypt password hashing helpers (12 rounds by default, configurable).
- SOC opaque token (D-006): secrets.token_urlsafe(32), bcrypt-hashed at
rest, plain value returned once at creation and never re-displayable.
- Group-based RBAC from day one (D-003) — Keycloak OIDC in v2 maps onto
the same group model.
- CleanupRenderer wraps jinja2.sandbox.SandboxedEnvironment with
StrictUndefined (no autoescape — shell context, not HTML).
- Custom filter regex_extract(text, pattern, group=1, default='') uses
google-re2 for linear-time matching (ReDoS-safe) and falls back to
re with a 1 MB input cap when re2 is absent.
- StepOutputs exposes {{ outputs.text }} and {{ outputs.blob('name') }}.
blob() decodes UTF-8 with latin-1 fallback, hard-capped at 10 MB
(consistent with F8 evidence limit, D-005).
- render_cleanup() is the module-level convenience wrapper.
- abstract C2Connector with authenticate / list_hosts / execute_task /
get_task_result / cancel_task / execute_cleanup; stream_task_output
optional v1 (NotImplementedError).
- Payload / TaskHandle / TaskResult / TaskStatus frozen dataclasses.
- UnsupportedPayloadType raised when no native command maps to the
chosen (c2_type, payload_type) pair.
- Mythic payload_type → native command map populated (spec §7 table).
- HOME map left empty until PR2 is closed.
- ConnectorFactory: register_connector decorator + build(c2_type) that
instantiates + authenticates via an injected config resolver.
No real Mythic / Home implementations land in this sprint.
- pyproject.toml with ruff + mypy strict + pytest + coverage >=70%
- Makefile with Docker/Podman auto-detect
- Multi-stage Dockerfile (python:3.12-slim-bookworm, non-root user)
- docker-compose.yml for Postgres dev DB
- alembic.ini wired to src/mimic/db/migrations
- scripts/postgres-init/00-roles.sql seeds the audit writer role
- .env.example documents every MIMIC_* var (no secrets committed)
D-011 freezes the regex_extract Jinja filter signature
`regex_extract(text, pattern, *, group=1, name=None)`, google-re2 engine,
raise on no-match — unblocks backend B0.5 templating sandbox.
D-012 splits storage in two pools: `blobs/` (CAS sha256 + gzip) for C2
binary outputs and `evidence/` (flat per engagement) for user uploads,
10 MB per-blob cap, no global quota v1.
Q-001 and Q-002 removed from open-questions.md (resolved).
Q-003/Q-004/Q-005 marked `deferred` with explicit re-open conditions.
Captures the four grey areas team-lead flagged in the sprint 0 brief
(regex_extract semantics, output_blob_ref storage, /hosts/sync merge
behaviour, payload_type↔home-C2 mapping) plus stale-host policy.
No decisions taken: each entry lists options, a recommended default
if no decision is reached, and a "becomes blocking when…" trigger.
Resolved questions will move to spec-decisions.md as D-NNN entries.
D-008 frames the group-based RBAC layout as an OIDC-prep mechanism that must
seed exactly the three F11 spec roles and their canonical permission matrix.
Custom groups remain out of v1 scope.
D-009 reaffirms H32: replayability lives only on run.snapshot_json. The
ttp_version table listed in B0.2 must be dropped from the initial migration.
