Owner

Proposal

Provide the executor's Rust workspace foundation and a typed Open Workflow Specification (OWS) DSL 1.0 parser, with the Ting normalization conventions needed by workflow callers.

Design

Create the executor crates under executor/. Parse OWS documents into a typed AST, then normalize use.workflows references and <workflow>@<impl> implementation selectors into one canonical representation.

Tasks

1.1 Scaffold the Rust crates and workspace in executor/.
1.2 Implement the OWS DSL 1.0 typed AST and parser, including the Ting normalization layer (use.workflows, <workflow>@<impl>).

Gherkin Specification Delta

must.contracts.ting-workflows.executor.dsl-parsing

Scenario: Parse and normalize an OWS DSL 1.0 workflow

GIVEN a valid OWS DSL 1.0 document containing use.workflows and a <workflow>@<impl> selector
WHEN the executor parses the document
THEN it returns a typed AST with the references normalized to the selected workflow implementation
AND malformed DSL is rejected with a structured parse error.
