# Estonia legislation IR (CID-keyed sparse GraphRAG)

Research retrieval release of `endomorphosis/ipfs_estonia_laws` (revision `902b122cd27eed93e96c28a0ba5a70e9cb36ab7d`) packaged as
`country-laws-ir-graphrag/v1` (layout family `skillcenter-huggingface-release/v3` / publicus-ir).

**Not legal advice.** This is a research snapshot. The official gazette /
authentic source of Estonia prevails over this corpus. Retrieved documents
and graph edges are retrieval evidence only. No legal text was invented.

Primary key: `entry_cid` (CIDv1 raw sha2-256 of a canonical identity record).
Integer `document_index` values are compact shard pointers, not identities.

Target Hub id (packaging metadata only): `justicedao/ipfs_estonia_laws_ir`.

## Counts

| Field | Value |
| --- | --- |
| Laws (corpus units) | 3484 |
| Articles (corpus units) | 62252 |
| Canonical docs | 66370 |
| BM25 terms | 236030 |
| BM25 postings | 8403964 |
| Graph nodes | 76826 |
| Graph edges | 464590 |
| Vectors | 66370 × 384-d `thenlper/gte-small` (embedded) |

## Canonical fields

`entry_cid`, `law_cid`, `record_type`, `jurisdiction`, `language`,
`instrument_id`, `instrument_title`, `article_number`, `article_title`,
`title`, `body`, `source_url`, `snapshot_date`, `coverage`, `license`,
`collector`, `source_dataset`, `source_revision`.

Unit policy: prefer article/section rows; fall back to law-level when
`articles.parquet` is empty.

## Index layout

Zstandard parquet shards with at most 4,096 rows.

- `indexes/bm25_keyword_shards.parquet` — lexical term ranges → BM25 posting shards
- `indexes/vector_chunks.parquet` — semantic routing centroids (rows sorted by cosine to shard centroid)
- `indexes/corpus_chunks.parquet` — document ranges → corpus shards
- `data/graph/nodes` / `data/graph/edges` — property graph
- `data/graph/adjacency/{incoming,outgoing}` — score-ordered neighbor pages

BM25: Okapi k1=1.2, b=0.75, title_weight=5, body_weight=1 (FTS5 unicode61-style tokenizer).

Graph: one node per `entry_cid` plus facet nodes (`_facet_cid(kind, value)` for
jurisdiction, language, instrument, source, status). Neighbor edges
`BM25_NEIGHBOR_OF` (k=8) carry score and matched terms. Structural edges:
`ARTICLE_OF` (article → parent law) when articles exist, plus `IDENTIFIED_BY_ELI`
/ `IDENTIFIED_BY` only when those identifiers are present in the source.

## Query

```
