MCP-free, browser-safe library that turns a neutral PassportDraft into an EU Digital Battery Passport in the official AAS format (IDTA 02035) and validates it in three layers.

import { emitAasJson, emitAasx, samples, validate } from '@passwerk/core';

const report = validate(samples['ev-valid']); // L1 -> emit -> L2 + L3, verdict 'valid'
const { output, verdict } = emitAasJson(draft); // canonical JSON, re-validated
const aasx = emitAasx(draft); // OPC package with the JSON inside, re-validated from bytes

PassportDraft: { meta, attributes: { [attributeId]: Field } } on the DIN DKE SPEC 99100 grain of @passwerk/rules. Numbers are decimal strings, dates ISO-8601.
Emitters read every idShort, semanticId and valueType from the bundled template catalogue.
Verdicts are valid, valid_with_warnings or invalid and always come from running the validators on the emitted output.

Emitters exist for IDTA 02035-1 (Nameplate), -3 (Carbon Footprint), -4 (Technical Data), -5 (Product Condition), -6 (Material Composition) and -7 (Circularity). Part 2 (Handover Documentation) follows with ingest in Phase 4 (ADR D-014).
