JuriCode-JP retrieval index and citation registry

Structured Japanese statutory law for retrieval, with a citation registry that lets a consumer verify that a quoted passage is byte-identical to the source text.

Path	What it is
`index/v0.2-aug-v9-gemini.npy`	Dense vectors, `float32`, shape `(143749, 3072)`
`index/v0.2-aug-v9-gemini.meta.jsonl`	One row per vector, in the same order: `chunk_id`, `article_id`, `law_id`, and section metadata
`registry/registry-2026-07/documents.jsonl`	One row per document, with its content hash
`registry/registry-2026-07/chunks.jsonl`	`chunk_id` -> document id
`registry/registry-2026-07/_manifest.json`	Provenance: `pipeline_version`, paired index, sha256 of inputs and outputs

Embedding model: gemini-embedding-001 (3072 dimensions, RETRIEVAL_DOCUMENT task type). Registry pipeline_version: w6-registry/2026-07.

The .npy row at position i corresponds to the .meta.jsonl row at position i.

What `hash_basis` means (read this before trusting a hash)

Every document in the registry carries a hash_basis field. The three values do not carry the same strength of evidence. Do not treat them as interchangeable.

`hash_basis`	Meaning
`egov-xml-canonical`	The text was checked against the e-Gov source XML. The hash is the one recorded in the per-law source manifest.
`egov-xml-derived`	Supplementary provisions (附則). Derived from the same source XML, but there is no per-article manifest anchor for them yet.
`juricode-stored-text`	The hash is over the text as stored here. It is self-reported. No external source was re-fetched to confirm it.

This distribution is not "all verified". It is verified where it says it is verified.

No pickle

Only .npy and .jsonl are distributed. The .vec.pkl file used internally is not published: it holds the same vectors as the .npy, and unpickling executes arbitrary code in the reader's process. A project whose value proposition is verifiability should not ship a format that asks the consumer to trust it.

Licensing

The structuring layer (schema, ids, chunking, this index) is MIT. The underlying texts are not ours to relicense: statutes come from e-Gov, circulars and tax guidance from the National Tax Agency, and rulings from the National Tax Tribunal; each is used under its own terms. See the source repository for the per-source table.

Comparing registries

Do not diff two registries with different pipeline_version values. A change in the pipeline changes how text is chunked and hashed, so a row-by-row diff across versions measures the pipeline, not the law.

Integrity

The sha256 of every file here is recorded in CHANGES.md in the source repository. That file is the anchor: it lets a third party confirm that what they downloaded is what was published, and that it was not replaced afterwards.
