* chore(papi): commit the sources behind the four polkadot-api packages papi-utils, bizinikiwi-bindings, metadata-builders and merkleize-metadata held only dist/ builds, and no repository held their source. Every source map in dist/ embeds the TypeScript it was compiled from; that is now committed as src/ (59 files), and it matches upstream polkadot-api (MIT) exactly once @polkadot-api/* imports are renamed: papi-utils @polkadot-api/utils 0.2.0 bizinikiwi-bindings @polkadot-api/substrate-bindings 0.16.6 metadata-builders @polkadot-api/metadata-builders 0.13.0-0.13.2 merkleize-metadata @polkadot-api/merkleize-metadata 1.1.21-1.1.23 scripts/check-papi-sources.mjs, run in the lint job, fails unless the source embedded in dist/ is exactly the committed src/. tsconfig.json excludes these src/ trees; ESLint already skipped the packages. Each README now states the upstream package and version. * chore(papi): keep the upstream sources in upstream-src/ The pezkuwi-dev build treats any package with a src/ directory as its own: it requires our license header on every file and builds it. These are upstream files that must stay byte-identical to the source embedded in dist/, so they live in upstream-src/ instead, which neither the build nor the root tsconfig picks up.

@pezkuwi/merkleize-metadata
Source: upstream-src/ is @polkadot-api/merkleize-metadata 1.1.22 from
polkadot-api (MIT), with imports of
@polkadot-api/* renamed to @pezkuwi/* (substrate-bindings → bizinikiwi-bindings). dist/ is its build;
scripts/check-papi-sources.mjs fails CI unless the source embedded in dist/ equals upstream-src/.
The upstream README follows.
@polkadot-api/merkleize-metadata
This TS package provides utils for the merkleization of frame_metadata as described in
RFC78.
Usage
import { merkleizeMetadata } from "@polkadot-api/merkleized-metadata"
const ksmMetadata = new Uint8Array(await readFile("ksm.bin"))
const merkleizedMetadata = merkleizeMetadata(ksmMetadata, {
decimals: 12,
tokenSymbol: "KSM",
})
// it returns the digest value of the metadata (aka its merkleized root-hash)
const rootHash = merkleizedMetadata.digest()
// given an extrinsic, it returns an encoded `Proof`
const proof1: Uint8Array = merkleizedMetadata.getProofForExtrinsic(
// Hex for the transaction bytes
