workbook-runtime — the RUNTIME-only leaf of the v0.5.0 compiler pipeline
(Phase 11, Plan 05 — Codex HIGH #2: the runtime/compiler LINK boundary).
This crate holds the owned IR types (Expr/BinOp/UnOp/RangeRef/Cell/
CellExpr/CellValue), the dependency Dag container + toposort, the
SERVE-time topo-ordered [run] executor, the manifest projection model, and a
PURE-RUST scalar leaf evaluator ([scalar_eval]) that REPLACES the
pmcp-code-mode (SWC/JS) kernel on the served-binary path.
It depends on NEITHER umya NOR SWC NOR pmcp-code-mode NOR quick-xml NOR
zip — making the Ph10 D-01 boundary a cargo-tree-PROVABLE LINK boundary. The
served binary (Plan 04) depends ONLY on this crate; workbook-compiler
re-exports these types FROM here so its public surface (and Plan 03) keeps
compiling unchanged.
