Usage

import {
  loadNetwork,
  parseBkn,
  validateNetwork,
  generateChecksum,
  verifyChecksum,
} from "@kweaver-ai/bkn";

// Load a network directory (auto-discovers network.bkn)
const network = await loadNetwork("examples/k8s-network");

// Parse a single file
const doc = parseBkn(text, { sourcePath: "path/to/file.bkn" });

// Validate network data tables
const result = validateNetwork(network);
if (!result.ok) {
  console.error(result.errors);
}

// Generate and verify checksum
await generateChecksum("examples/k8s-network");
const { ok, errors } = await verifyChecksum("examples/k8s-network");

• parseBkn(text, options?) — Parse .bkn/.bknd text into BknDocument
• loadBknFile(path, options?) — Load and parse a single file

• discoverRootFile(directory) — Find network root file
• validateDocument(doc, options?) — Validate document structure
• validateNetwork(network, options?) — Validate all data tables
• validateDataTable(table, schema?, network?) — Validate a data table
• generateChecksum(path, options?) — Generate CHECKSUM file
• verifyChecksum(path, options?) — Verify CHECKSUM file
• packToTar(sourceDir, outputPath, options?) — Pack BKN directory to tar (macOS: COPYFILE_DISABLE=1)
