Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for browser cookies, localStorage, sessionStorage, IndexedDB, Cache Storage, service workers, offline caches, and client-side session persistence. Use when the user asks to inspect browser state, replay cached auth or session behavior, explain why a page behaves differently after load, or trace how stored client state changes requests, rendering, or access.

Thread-safe data persistence in Swift using actors — in-memory cache with file-backed storage, eliminating data races by design.
Use when implementing data persistence in iOS apps with SwiftData or CoreData, encountering migration errors, performance issues with fetches, or choosing between persistence frameworks
Thread-safe data persistence in Swift using actors — in-memory cache with file-backed storage. Use when building local storage layers, offline-first patterns, or any shared mutable state that needs both concurrency safety and disk persistence.
