continueert

Continueert is a theoretical construct in computer science describing a persistent program continuation that can be captured, serialized, and resumed after an interruption. In this model, the exact point of execution and its surrounding environment are preserved so computation can continue from the same state on a later time or different host.

A continueert encapsulates the active control stack, heap objects, and binding environment. It is typically represented as a portable, platform-independent snapshot that may be transferred across processes or machines. Implementations discuss APIs for creating, serializing, deserializing, and resuming a continueert, often with security and isolation considerations.

Continueerts share goals with continuations, checkpoints, and persistent data structures, but emphasize cross-system portability and resumability after restart. They are discussed in theoretical literature and in some experimental systems, where they enable process migration, fault-tolerant workflows, and long-running computations without restarting from the beginning.

Challenges include the complexity of capturing a live program state, performance overhead of serialization, and potential nondeterminism. Security risks arise if a continueert is transported with executable privileges. As a concept, it remains largely experimental and is not part of mainstream programming languages.

Notable related concepts include continuations, snapshot/checkpointing, and process migration. Practical implementations often resemble staged checkpoints or persistent coroutines rather than a universal standard, and debates continue about the best interfaces, guarantees, and portability requirements for continueert-like mechanisms.
