//! Workflow, artifact, and run-record builtin signatures.
//!
//! Three sub-areas:
//!
//! - `artifact_*` / `handoff*` / `assemble_context` — typed-record
//!   constructors and selectors that produce `ArtifactRecord`-shaped
//!   dicts the orchestration runtime understands.
//! - `workflow_*` graph-shape builders/validators (`workflow_graph`,
//!   `workflow_validate`, ...) plus `workflow.*` mailbox primitives
//!   (signal/query/update/...).
//! - `run_record_*` and `eval_*` for replay fixtures and eval suites.
