#Errors

Every error thrown by @teakit/sheet is a SheetError carrying a stable code from the SheetErrorCode union (all SHEET_-prefixed).

import { Sheet, SheetError } from "@teakit/sheet";

try {
  Sheet.from(new Map());
} catch (error) {
  if (error instanceof SheetError) {
    error.code; // "SHEET_INVALID_SHEET"
  }
}

#Agent Notes

• Branch on error.code, not on error.message (messages are not stable).
• Import the type with import { SheetError } from "@teakit/sheet".
• Each method reference lists the exact codes it can throw under Throws.
