This repository is the ready-to-run data companion for Forest.Wikipedia.EN on GitHub. It combines a pinned Kiwix English Wikipedia canopy with a sealed semantic projection, canonical title inventory, and pinned query model.

Search tells you where to look. It does not declare a retrieved article true, relevant, or authoritative for your project.

Quick start

pip install "wiki-forest[semantic]"
wiki-forest setup
wiki-forest search "how communities preserve memory"

The installer downloads this exact release, resumes interrupted transfers, verifies every declared SHA-256 checksum, and creates a fresh local custody database.

bundle-manifest.json

bundle-manifest.json is the release boundary. It names every required file, byte length, and SHA-256 digest. Forest.Wikipedia.EN refuses an incomplete or altered bundle.

What the canopy contains

Kiwix's all_mini archive contains article titles, introductions, and infoboxes without images. Bearing lookup and semantic search therefore work completely offline after installation.

Full article sections are intentionally not bundled. When someone enters an article, Forest.Wikipedia.EN fetches an exact Wikimedia revision, stores the immutable body by content hash, and pins that revision locally. New installations contain no personal hydration history.

Intended use

Local Wikipedia discovery without sending search queries to a hosted service.
A shared knowledge terrain for agents or interactive research tools.
Reproducible semantic retrieval experiments over Wikipedia leads.
A populated backend for applications implementing the Forest boundary.

Not intended as

A claim that Wikipedia content is ground truth.
A complete offline copy of full English Wikipedia articles.
A replacement for article citations or revision histories.
A pre-populated record of any user's reading or retrieval history.

Retrieval design

Production search preserves exact and lexical Kiwix candidates, adds a wide IVF-PQ semantic neighborhood, reranks that bounded set from memory-mapped SQ8 codes, and applies diversity selection. Returned titles are unread directions; the consuming application decides what crosses its boundary.

The sealed production run contains all 8,419,072 canonical bearings with zero title-only projection fallbacks. Construction details and validation benchmarks live in the GitHub repository's DESIGN.md.

Versioning

Applications should pin a release tag or Hub commit. Do not treat moving main as a reproducible data identity. The Forest.Wikipedia.EN code release records the exact Hub revision it expects, and the local identity command reports the mounted canopy and semantic fingerprints.

Data provenance and licensing

This is a mixed-provenance artifact:

Wikipedia content was written by Wikimedia contributors and retains its applicable Wikimedia licenses and attribution requirements.
The unchanged offline archive was published by Kiwix in the openZIM format.
The query encoder is BAAI/bge-small-en-v1.5 at the revision sealed in the bundle manifest and retains its upstream terms.
Forest.Wikipedia.EN's original source code is MIT licensed.
