Summary	Pass a request through a sequence of handlers until one handles it or the chain ends.	—	—
Intent	Pass requests along a chain of handlers until one of them handles the request or the request reaches the end of the chain.	Allow an object to alter its behavior when its internal state changes by delegating state-specific behavior to separate state objects.	Encapsulate a family of algorithms or behaviors behind a common contract so they can be selected and swapped cleanly.
Decision factors
Problem	A request must pass through multiple possible handlers, but the sender should not need to know which handler will process it.	An object behaves differently depending on its internal state, and conditional logic is becoming hard to manage.	A system needs to switch between interchangeable behaviors without hardcoding branching logic everywhere.
Tradeoffs	Requests can become harder to trace because control flows through multiple handlers. A long chain may add overhead if many handlers are checked on every request. It keeps handler logic isolated and easier to extend.	Can introduce many small classes if the state graph is large State transitions may become harder to trace if spread across multiple classes	Adds more moving parts than a direct conditional approach Works best when behavior variations are real and likely to grow

Integration notes	Chain of Responsibility is useful for validation pipelines, support routing, approval flows, and any system where requests may be processed by different handlers in sequence.	State is useful for workflows, media players, order lifecycles, and any domain where behavior changes as the object moves through a lifecycle.	Strategies can cross codebases through shared contracts, API selection rules, or runtime configuration.
