VALIDATION-PLANES-12: Typed table columns with a per-row constraint

What it demonstrates

table({columns, cells, minRows}) types each named column with Zod and flags a bad cell at that row’s source line.

Builds on: VALIDATION-PLANES-07: Require a block kind: a table

How it’s done

A TypeScript program against the library API; inline comments show the resulting values and behavior.

const c = contract({ body: sections({}, [
  section("Changes", { content: table({
    columns: ["File", "Kind"],
    cells: { Kind: z.enum(["add", "modify", "delete"]) },
    minRows: 1,
  }) }),
]) });
// a row whose Kind is "tweak" -> content/table/cell at that row's line

Surfaces exercised

• table() cells / minRows (src/core/leaves.ts)
• per-column Zod over each row (src/core/content.ts validateTable)
• content/table/cell pinned via rowPos(i)
