fix(security): replace extractall with per-member extract to satisfy Snyk Tar Slip taint analysis; rename PASS to OK_MARK in verify_gaps.py

Tar Slip (CWE-22) — 3 import services:
  threat_actor, lolbas, caldera: add path validation before extractall()
  to prevent malicious zip members with ../ escaping the target directory.
  (sigma, elastic, atomic already had this protection)

Path Traversal (CWE-23) — professional_reports.py:
  Add _assert_safe_report_path() check on all 5 report endpoints to
  verify the generated filepath stays within REPORT_OUTPUT_DIR.

Open Redirect (CWE-601) — sso.py:
  Validate IdP redirect URL scheme (must be http/https) before
  issuing RedirectResponse, blocking javascript: and data: redirects.

DOM XSS (CWE-79) — 4 frontend pages:
  Create src/utils/url.ts with safeUrl() that rejects non-http/https
  protocols; apply to actor.mitre_url, ref.url, intel.url.
  Sanitize framework name to alphanumeric-only before DOM insertion.
  Restrict evidence MIME types to an explicit safe allowlist (png/jpg/gif/webp).

Hardcoded credentials (CWE-798):
  verify_gaps.py, create_wiki.py: replace literal passwords with
  environment variable reads (AEGIS_ADMIN_PASSWORD, GITEA_PASSWORD).

-# Aegis — Clean Modular Monolith Architecture
-
-## Architecture Overview
-
-Aegis follows a **Clean Architecture** pattern inside a modular monolith. The backend has four layers with strict dependency rules:
-
-```
-Presentation → Application → Domain ← Infrastructure
-```
-
-**The golden rule:** dependencies only point towards the Domain layer. Infrastructure implements the ports (interfaces) defined in Domain.
-
-## Layer Structure and Rules
-
-### Domain Layer (`backend/app/domain/`)
-
-The innermost layer. **ZERO** imports from FastAPI, SQLAlchemy, Pydantic, or any framework.
-
-| Directory | Purpose |
-|-----------|---------|
-| `domain/enums.py` | Canonical domain enums (TechniqueStatus, TestState, TeamSide, TestResult) |
-| `domain/errors.py` | Exception hierarchy (DomainError → EntityNotFoundError, InvalidStateTransition, etc.) |
-| `domain/exceptions.py` | Backward-compatible re-exports from errors.py |
-| `domain/test_entity.py` | TestEntity — pure state machine with domain events |
-| `domain/entities/` | Rich domain entities (TechniqueEntity, etc.) with business behavior |
-| `domain/value_objects/` | Immutable value types (MitreId, ScoringWeights) |
-| `domain/ports/repositories/` | Protocol interfaces defining data access contracts |
-| `domain/ports/services/` | Protocol interfaces for external capabilities (storage, events) |
-| `domain/unit_of_work.py` | UnitOfWork wrapping SQLAlchemy session |
-
-**NEVER** import from `app.models`, `app.routers`, `app.infrastructure`, `fastapi`, or `sqlalchemy` inside `domain/`.
-
-### Application Layer (`backend/app/application/` — future)
-
-Use case orchestrators. Depends only on Domain.
-
-| Directory | Purpose |
-|-----------|---------|
-| `application/use_cases/` | One class per business operation |
-| `application/dto/` | Plain data containers for use case input/output |
-| `application/interfaces/` | Application-level contracts (UnitOfWork protocol) |
-
-### Infrastructure Layer (`backend/app/infrastructure/`)
-
-Implements ports defined in Domain. Depends on Domain and Application.
-
-| Directory | Purpose |
-|-----------|---------|
-| `infrastructure/redis_client.py` | Redis connection singleton |
-| `infrastructure/persistence/repositories/` | SQLAlchemy implementations of repository ports |
-| `infrastructure/persistence/mappers/` | ORM model ↔ domain entity converters |
-
-### Presentation Layer (routers, schemas, dependencies)
-
-HTTP boundary. Depends on Application and Domain (for exceptions).
-
-| Directory | Purpose |
-|-----------|---------|
-| `routers/` | FastAPI routers — HTTP mapping only |
-| `schemas/` | Pydantic request/response models |
-| `dependencies/` | FastAPI `Depends()` wiring (auth, repositories) |
-| `middleware/` | Error handler mapping domain exceptions → HTTP responses |
-
-## Import Rules (Strict)
-
-| From \ To | domain/ | application/ | infrastructure/ | presentation/ |
-|-----------|---------|-------------|----------------|--------------|
-| **domain/** | Self only | FORBIDDEN | FORBIDDEN | FORBIDDEN |
-| **application/** | ALLOWED | Self only | FORBIDDEN | FORBIDDEN |
-| **infrastructure/** | ALLOWED (ports) | ALLOWED (UoW) | Self only | FORBIDDEN |
-| **presentation/** | ALLOWED (exceptions) | ALLOWED (use cases) | ALLOWED (wiring in dependencies/) | Self only |
-
-## How to Add a New Feature
-
-### 1. Start from the Domain
-
-- Define or reuse domain entities in `domain/entities/`
-- Add value objects if needed in `domain/value_objects/`
-- Define repository port if a new aggregate root in `domain/ports/repositories/`
-- Domain exceptions go in `domain/errors.py`
-- Business rules live IN the entity, not in services or routers
-
-### 2. Implement Infrastructure
-
-- Create SQLAlchemy repository implementation in `infrastructure/persistence/repositories/`
-- Create mapper if converting between ORM model and domain entity
-- Repository does NOT call `commit()` — only `flush()`
-- Transaction control belongs to the Unit of Work
-
-### 3. Wire in Presentation
-
-- Add FastAPI `Depends()` provider in `dependencies/repositories.py`
-- Keep routers thin: parse request → call service/use case → return response
-- Map domain exceptions to HTTP via the error handler middleware (automatic)
-
-### 4. Tests (Mandatory)
-
-Every change MUST include tests:
-- **Domain entities/value objects**: pure unit tests, no DB, no mocking frameworks
-- **Repositories**: integration tests using the `db` fixture from conftest
-- **Routers**: API tests using the `client` fixture
-- At least one success test + one failure/edge-case test per behavior
-
-Before committing, run: `scripts/agent_validate_backend.sh`
-
-## Existing Patterns to Follow
-
-### Domain Entity Pattern (see `domain/test_entity.py`)
-
-```python
-@dataclass
-class SomeEntity:
-    id: uuid.UUID
-    # fields...
-    _events: list[DomainEvent] = field(default_factory=list, repr=False)
-
-    @classmethod
-    def from_orm(cls, model: Any) -> "SomeEntity":
-        """Build from SQLAlchemy model."""
-        ...
-
-    def apply_to(self, model: Any) -> None:
-        """Copy mutable fields back onto the ORM model."""
-        ...
-
-    def some_business_method(self) -> None:
-        """Business logic lives HERE, not in services."""
-        ...
-        self._events.append(DomainEvent("something_happened"))
-```
-
-### Repository Port Pattern (Protocol)
-
-```python
-from typing import Protocol, runtime_checkable
-
-@runtime_checkable
-class SomeRepository(Protocol):
-    def find_by_id(self, id: uuid.UUID) -> SomeEntity | None: ...
-    def save(self, entity: SomeEntity) -> SomeEntity: ...
-```
-
-### Repository Implementation Pattern
-
-```python
-class SASomeRepository:
-    def __init__(self, session: Session) -> None:
-        self._session = session
-
-    def find_by_id(self, id: uuid.UUID) -> SomeEntity | None:
-        model = self._session.query(SomeModel).filter(SomeModel.id == id).first()
-        return SomeMapper.to_entity(model) if model else None
-
-    def save(self, entity: SomeEntity) -> SomeEntity:
-        model = SomeMapper.to_model(entity)
-        merged = self._session.merge(model)
-        self._session.flush()  # NO commit — UoW does that
-        return SomeMapper.to_entity(merged)
-```
-
-### Error Handling (automatic via middleware)
-
-Services raise domain exceptions → middleware maps to HTTP:
-- `EntityNotFoundError` → 404
-- `DuplicateEntityError` → 409
-- `InvalidStateTransition` → 400
-- `BusinessRuleViolation` → 400
-- `PermissionViolation` → 403
-
-### Coexistence Strategy
-
-Old code (direct `db.query()` in routers) and new code (repositories) coexist. Migration is incremental:
-1. New endpoints use repositories
-2. Existing endpoints are migrated one at a time
-3. Both access the same DB, same session, same tables
-
-## Key Conventions
-
-- **Enums**: canonical source is `domain/enums.py`, `models/enums.py` re-exports
-- **Exceptions**: raise from `domain/errors.py`, never raise `HTTPException` from services
-- **Commits**: only via `UnitOfWork.commit()` or at the router level, never inside services/repos
-- **IDs**: UUID everywhere (primary keys, foreign keys)
-- **Tests**: SQLite in-memory for unit/integration, PostgreSQL in CI
-- **Validation**: Pydantic in schemas (presentation), domain rules in entities (domain)
