Dynamically discovers and registers scanner parsers by scanning the dojo/tools directory. Each parser module implements a consistent interface (get_scan_types, get_findings, etc.), enabling pluggable support for hundreds of security tools. The factory is decoupled from individual parser logic and can be reused in any project needing a plugin-based import system.

Implements a modular authorization filter registry where permission-scoping functions are registered per model. This avoids hardcoded permission checks and allows new models to opt into fine-grained RBAC by registering a filter function. The pattern is reusable for any Django app requiring extensible authorization scoping.

Defines the BaseLocationManager abstract class and LocationHandler facade to abstract over the legacy Endpoint model and the new Location model, controlled by a feature flag. This pattern cleanly isolates the transition between two data models and can be adapted for other migration scenarios where parallel implementations must coexist without code duplication.

Provides a custom HTTP session with SSRF protection by validating IP addresses against private/subnet ranges and enforcing a whitelist/deny-list. Overrides urllib3 and requests connection classes to prevent server-side request forgery. This is a self-contained security utility that can be extracted into any Python project needing safe outbound HTTP.

Implements a per-request (or per-Celery-task) in-memory cache using thread-local storage. Provides @cache_for_request and @cache_for_request_or_task decorators to memoize function results within the same request/task lifecycle. This lightweight caching pattern reduces redundant database queries and is easily reusable in any Django/Celery project.
