Usage

import { attributes, getAttribute, getAttributesForCategory, templates, listCapabilities } from '@passwerk/rules';

const mass = getAttribute('batteryMass');
mass?.name.de;                 // "Batteriemasse"
mass?.applicability.LMT;       // { status: "mandatory" }
mass?.legalRefs;               // ["BR Annex VI Part A (5)", "DIN longlist: Annex XIII (1a); Annex VI Part A (5)"]
mass?.templateElements[0]?.semanticId;

getAttributesForCategory('EV', ['mandatory']).length;
templates[5]?.environment;     // IDTA 02035-6 Material Composition, AAS V3.0 JSON
listCapabilities();            // versions, checksums, counts, sovereignty statement

Maintenance

pnpm --filter @passwerk/rules run artefacts          # fetch + verify against pinned checksums
pnpm --filter @passwerk/rules run artefacts:write    # re-pin after a deliberate upstream update
pnpm --filter @passwerk/rules run artefacts:verify   # offline verification only
pnpm --filter @passwerk/rules run generate           # regenerate kb/generated/* and PROVENANCE.md

The test suite fails if a bundled file does not match its checksum, if a generated file is stale, or if any attribute references an unknown longlist row, EC data point or template path.

Honesty flags

Attributes and timeline events carry verify: true when the mapping or date came from a secondary source or a judgement call. listCapabilities() reports how many are open. Nothing in this package is legal advice.
