charter-core 0.0.1

Durable workflow engine for delegated responsibilities (runtime internals).

charter-core

Internal runtime package for Charter. It owns workflow schema validation, step execution, run state, event models, artifact stores, and runtime adapters used by the CLI, daemon, and gateway-facing worker code.

charter-core is not a supported embedding SDK. The package root intentionally does not export runner lifecycle helpers such as start, resume, or submit_input; Charter's supported product interfaces are the CLI and the gateway/control plane.

Use This Package When

• You are developing Charter runtime packages such as charter-cli.
• You need shared run protocol, event, state, or storage models inside Charter infrastructure.

For workflow authoring and local execution, use charter-cli. For custom provider or tool integrations, use charter-integration-sdk.

Internal Boundaries

• charter-core depends on charter-integration-sdk because the runner consumes and enforces the integration contract.
• charter-core must not depend on the CLI or provider implementations.
• HTTP clients, terminal UX, and provider-specific code live outside this package.

Submodule Map

• runner: workflow start/resume/input execution internals
• runtime: managed run lifecycle used by daemon mode
• schema: workflow plan and form schema models
• state, event_store: persisted run and stream contracts
• storage, stores: project storage configuration and built-in adapters
