kestrel.markets/src/lang/index.ts

A typed, token-efficient language + runtime for agentic trading: agents author bounded plans, the runtime fires them at the tick. CLI + typed library + MCP server.

/**
 * # lang — the DSL core: the typed object model, the canonical printer, and builders
 *
 * The typed TS object model IS the language (ADR-0004); text is a projection of it. This
 * barrel re-exports the three surfaces of that model:
 *
 * - {@link ./ast.ts} — the discriminated-union node family for all four statement kinds
 *   (View / Wake / Plan / Grade), the org nodes (Pod / Book), and the shared lexical core
 *   (Trigger algebra, Series references, Price expressions).
 * - {@link ./print.ts} — `print(node)`, the canonical printer (objects -> byte-stable
 *   text), fail-closed.
 * - {@link ./parse.ts} — `parse(text)` / `parseMarkdown(text)`, the inverse projection
 *   (text -> objects), fail-closed with `line`/`col` on every error.
 * - {@link ./builders.ts} — the ergonomic programmatic authoring surface.
 *
 * This barrel is the ONLY import surface other `src/` modules may use for the language.
 * `parse ∘ print` and `print ∘ parse` are inverse projections with a byte-stable canonical
 * form (ADR-0004).
