GetBible Study Builder v1

v1_study_builder converts policy-approved CrossWire SWORD commentary and dictionary modules into two independently deployable static JSON APIs:

• https://commentaries.getbible.net/v1/ from getbible/v1_commentaries
• https://dictionaries.getbible.net/v1/ from getbible/v1_dictionaries

The Bible API v3 builder remains unchanged. Study Builder deliberately uses the same book numbers, chapters, verses, and Strong's keys so a client can move from a Bible response to commentary or dictionary data with a direct path lookup.

Repository boundaries

Repository	Responsibility	Runtime
getbible/getbiblesword	Official SWORD C++ extraction and deterministic NDJSON	Released Linux executable
getbible/v1_study_builder	Download policy, strict contract validation, normalization, schemas, and publication	Python 3.12 at build time
getbible/v1_commentaries	Generated commentary JSON under v1/	Nginx/CDN only
getbible/v1_dictionaries	Generated dictionary JSON under v1/	Nginx/CDN only

Study Builder does not contain C++, link libsword, use a Python SWORD binding, or parse a module's binary driver format. getbiblesword is a separately versioned subprocess dependency.

Extraction dependency

conf/getbiblesword.json pins release v0.1.1, contract getbiblesword.ndjson/v1, and the exact x86-64/ARM64 Linux asset names and SHA-256 digests. On first use the builder:

1. constructs the direct public download URL for the pinned tag and asset;
2. downloads the architecture-specific archive without calling the GitHub API;
3. verifies it against the SHA-256 digest committed in the manifest;
4. safely extracts only usr/bin/getbiblesword;
5. checks the executable's reported version and contract;
6. caches it under .work/tools/getbiblesword/0.1.1/.

The getbible/getbiblesword repository and its pinned release are public, so installation requires no repository token or GitHub API request. The automated smoke, integration, and production builds all exercise this unauthenticated path.

Install or verify it explicitly:

study-builder engine install
study-builder engine verify

An audited local executable can be selected with --engine /absolute/path or STUDY_BUILDER_GETBIBLESWORD; it must still report the pinned version and contract.

Independent contract validation

The builder treats extractor output as untrusted. It reads NDJSON incrementally and independently checks all of the rules that protect publication:

• getbiblesword.ndjson/v1 header and extract command;
• canonical top-level member order and zero-based monotonic sequence values;
• base64 decoding, byte size, SHA-256, and matching UTF-8 convenience fields;
• entry/configuration ordinals and module classification;
• artifact identifiers, chunk indexes, reconstructed size, and SHA-256;
• exact stream SHA-256 over every line before the footer, including LF;
• exact footer record/entry/artifact/byte counts and success: true.

Raw bytes remain authoritative. The adapter derives safe text/HTML for the public API only after verification and retains the original contract records internally. Any missing footer, checksum failure, failed diagnostic, extractor error, or classification mismatch stops the complete build before publication.

Commentary API

GET https://commentaries.getbible.net/v1/commentaries.json
GET https://commentaries.getbible.net/v1/{commentary}/metadata.json
GET https://commentaries.getbible.net/v1/{commentary}/books.json
GET https://commentaries.getbible.net/v1/{commentary}/{book}.json
GET https://commentaries.getbible.net/v1/{commentary}/{book}/{chapter}.json

The chapter path is the primary high-volume endpoint. book is the GetBible API v3 numeric identifier: Genesis is 1, Matthew 40, and Revelation 66. Each entry contains its natural Bible coordinate:

{
  "schema": "getbible-commentary-chapter-v1",
  "commentary": "clarke",
  "language": "en",
  "book": 43,
  "name": "John",
  "chapter": 1,
  "entries": [
    {
      "book": 43,
      "chapter": 1,
      "verse": 1,
      "name": "John 1:1",
      "anchor": {"book": 43, "chapter": 1, "verse": 1, "osis": "John.1.1"},
      "text": "...",
      "html": "<p>...</p>"
    }
  ]
}

Book and chapter introductions use chapter or verse 0; they are not discarded.

Dictionary API

GET https://dictionaries.getbible.net/v1/dictionaries.json
GET https://dictionaries.getbible.net/v1/{dictionary}/metadata.json
GET https://dictionaries.getbible.net/v1/{dictionary}/keys.json
GET https://dictionaries.getbible.net/v1/{dictionary}/{entry}.json
GET https://dictionaries.getbible.net/v1/{dictionary}/indexes/{sha256-prefix}.json

Strong's paths match Bible API v3 tokens directly:

G3056 -> https://dictionaries.getbible.net/v1/strongsgreek/G3056.json
H0430 -> https://dictionaries.getbible.net/v1/strongshebrew/H0430.json

Greek keys use G plus the unpadded number; Hebrew keys use H0 plus the unpadded number. Other dictionary keys receive deterministic, path-safe IDs. keys.json maps source keys and aliases, while 256 SHA-256-prefix shards provide smaller lookup indexes for constrained clients.

Some SWORD dictionaries legitimately contain more than one definition for the same public key. The first definition keeps the canonical direct path, and later definitions receive deterministic --2, --3, and subsequent suffixes. For example, Easton's repeated KADESH records are available as k-KADESH.json and k-KADESH--2.json. Every definition appears in keys.json with an occurrence value. Dictionary metadata reports both the total entry_count and the distinct unique_key_count.

Loading

The static output is the system of record. Nginx and a CDN can serve direct lookups without an application process, database connection pool, or request throttling bottleneck.

Local development

python3.12 -m venv .venv
source .venv/bin/activate
python -m pip install -e '.[dev]'

study-builder engine install
python -m ruff check src tests scripts
python -m ruff format --check src tests scripts
python -m pytest

Inspect current redistribution decisions without downloading module packages:

study-builder catalog
study-builder catalog --resource dictionaries --json

Build both resources into dist/:

study-builder build --resource all

Build and validate one module without publication:

study-builder build --resource commentaries --module Clarke --refresh
python scripts/validate_build.py --resource commentaries --module Clarke

Partial module builds are deliberately prohibited from --push. A complete local publication run is:

study-builder build --resource all --pull --push

Use --offline only after catalog and package caches exist. Use --dry-run to show approved work without downloading packages or installing the extractor.

Automation

Workflow	Trigger	Result
ci.yml	pull request, branch push, manual	Ruff, formatting, unit tests, malicious-contract rejection, CLI checks
binary-smoke.yml	relevant pull request, main push, manual	Public release install/verification plus real Clarke and StrongsGreek JSON builds
integration.yml	monthly, manual	Real builds of Clarke, TSK, MHCC, StrongsGreek, StrongsHebrew, and Easton; validates static lookup shape
build.yml	monthly, manual	Complete selected resource build; conditionally signs and pushes both output repositories

The production workflow always builds. It pushes only when the push input is enabled and all six publication values are non-empty. With incomplete publication secrets it emits a notice, produces the local build and report, and skips Git setup, cloning, commits, and pushes.

No extractor-access secret is required. binary-smoke.yml proves that the pinned public release can be installed, verified, and used without authentication.

Publication secret set:

Secret	Purpose
GETBIBLE_GIT_USER	Commit author name
GETBIBLE_GIT_EMAIL	Commit author email
GETBIBLE_GPG_KEY	ASCII-armored signing private key
GETBIBLE_GPG_USER	Signing identity
GETBIBLE_SSH_KEY	SSH private key with write access to both outputs
GETBIBLE_SSH_PUB	Matching public key

The default output remotes are getbible/v1_commentaries and getbible/v1_dictionaries. Optional GETBIBLE_COMMENTARIES_REPO and GETBIBLE_DICTIONARIES_REPO secrets may select staging remotes.

Redistribution policy

CrossWire availability is not permission to republish a transformed module. conf/module_policy.json is fail-closed: explicit denial wins, reviewed module approval may opt in a module, and otherwise only exact allowlisted license values are built. Unknown or missing licenses are skipped. Generated metadata retains the module's license, copyright, holder/contact, text source, and distribution notes.

Docker

docker build -t getbible-study-builder:1 .
docker run --rm \
  -v "$PWD/dist:/app/dist" \
  getbible-study-builder:1 build --resource all

The public pinned extractor is downloaded and verified at runtime, then cached if .work/ is mounted.

License

The Study Builder source is GPL-2.0-only. getbiblesword is distributed separately under GPL-2.0-only with its corresponding SWORD source release. SWORD modules remain separate works under their individual licenses.
