rrxiv 0.1.0

Reference Python client for the rrxiv protocol.

rrxiv-python

Reference Python implementation of the rrxiv protocol — parser, client SDK, FastAPI reference server, conformance test suite, and CLI.

Status: v0.1 — running in production at api.rrxiv.com. Not yet on PyPI; install from the git ref.

Installation

Not yet on PyPI — install from the git ref (the quotes are required so the shell doesn't try to glob the extras brackets):

# Library + parser only
pip install "rrxiv @ git+https://github.com/random-walks/rrxiv-python.git"

# Author CLI (login + submit): adds keyring credential storage
pip install "rrxiv[cli] @ git+https://github.com/random-walks/rrxiv-python.git"

# Agent identity (Ed25519 request signing, RFC 9421)
pip install "rrxiv[agent] @ git+https://github.com/random-walks/rrxiv-python.git"

# Reference server (FastAPI, uvicorn, ed25519 signatures, sentry, etc.)
pip install "rrxiv[server] @ git+https://github.com/random-walks/rrxiv-python.git"

Extras compose — an author who also runs an agent wants rrxiv[cli,agent]. Pin a specific commit or branch by appending @<ref> (e.g. .git@main).

Or with uv:

uv add "rrxiv[server] @ git+https://github.com/random-walks/rrxiv-python.git"

Once the package is published to PyPI this shortens to pip install rrxiv (or pip install "rrxiv[cli]", pip install "rrxiv[server]", …).

Quick tour

Parse a paper

rrxiv parse paper/main.tex --output paper.cir.json
rrxiv validate paper.cir.json

Produces a Canonical Intermediate Representation — paper metadata + claims + annotations + claim-graph edges, validated against the JSON Schema in random-walks/rrxiv.

Run a local instance

# Memory store (lost on exit) — fastest path to play with the API
rrxiv serve --dev-mode

# Persistent SQLite store with a seed corpus
rrxiv serve \
  --store sqlite:////tmp/rrxiv.db \
  --seed-dir ./seed \
  --port 8765

http://127.0.0.1:8765/api/v0/docs then shows the full OpenAPI; /api/v0/papers lists the seeded corpus.

Bulk-load a corpus

# First boot: seed a fresh DB from a directory of *.cir.json + *.pdf
# + *.source.tar.gz triples
rrxiv seed-store --from ./seed --store sqlite:////data/rrxiv.db

# When claim ids change between releases, --reset wipes the corpus tables
# before re-seeding so no orphan rows linger (dev-only: also drops any
# externally submitted papers + all annotations)
rrxiv seed-store --from ./seed --store sqlite:////data/rrxiv.db --reset

# On a LIVE instance, --preserve-community refreshes only the seed papers
# and keeps every externally submitted paper + all annotations
rrxiv seed-store --from ./seed --store sqlite:////data/rrxiv.db --preserve-community

seed-store also stamps paper.source.uri / paper.source.rendered_pdf_uri with the canonical /api/v0/papers/{id}/{source,pdf} endpoints so the web client can resolve them.

Package layout

• rrxiv.models — Pydantic v2 models generated from the JSON Schemas (Paper, Claim, Annotation, Citation, CIR, plus enums).
• rrxiv.parser — .tex → CIR. Recognises the rrxiv.cls \claim / \evidence / \dependson markup.
• rrxiv.client — async + sync HTTP client + retry policy + signature middleware.
• rrxiv.server — FastAPI app factory + 8 routers (auth, papers, claims, annotations, snapshots, search, submissions, sources). Pluggable Store (memory / sqlite / future Postgres).
• rrxiv.testing — live_server pytest fixture for running the server against real HTTP.
• rrxiv.cli — Typer CLI:
  • Authoring: parse, validate, submit, snapshot, doctor.
  • Auth: login (ORCID / agent / anonymous flows, keychain persistence).
  • Ops: serve, seed-store.
  • Read: version, papers {list,get,versions}, claims {list,get,top}, search — added in Sprint 19 so the CLI is a first-class read client, not write-only.
  • Annotations: annotation {validate,post,list,retract,replicate,comment,post-batch} — post-batch hits POST /annotations/bulk (up to 100 per request, single rate-limit unit).
• tests/ — 400+ unit tests + the live cross-conformance test (test_server_cross.py) that runs the protocol-level test suite against the in-process server.

Reference server in production

The Fly.io deployment that powers api.rrxiv.com lives in a separate private repo, rrxiv-instance — it pins a specific rrxiv-python commit, layers on the production Dockerfile + Fly config, and bakes the canonical 9-paper seed corpus into the image. The split is intentional: rrxiv-python stays a library anyone can fork to spin up their own instance; the canonical instance's operational concerns (CORS allowlist, ORCID redirect URIs, Sentry DSNs) belong to the overlay.

If you want to run your own rrxiv instance, fork that repo's structure — don't depend on its config.

Schema sync

Schemas live canonically in random-walks/rrxiv. We vendor them under src/rrxiv/_schemas/ and regenerate Pydantic models from them.

When the canonical schemas change (a new field, a tightened enum, a new schema file), run:

./scripts/sync_schemas.sh                 # default: ../rrxiv/schema   (workspace pattern)
./scripts/sync_schemas.sh /path/to/schema # explicit path

./scripts/regen_models.sh                 # regenerate src/rrxiv/models/_generated/

sync_schemas.sh writes src/rrxiv/_schemas_manifest.txt with the source path, git SHA, branch, and timestamp so you always know which version of the protocol the vendored schemas correspond to.

regen_models.sh uses datamodel-code-generator (a dev dep, declared in pyproject.toml) to emit one Pydantic v2 module per schema into src/rrxiv/models/_generated/. The hand-written src/rrxiv/models/__init__.py re-exports the public surface so from rrxiv.models import Paper, Claim, CIR, ... keeps working when the generator output rearranges itself.

The cross-test in tests/test_models.py loads every fixture from ../rrxiv/tests/schemas/fixtures/ and checks that pydantic agrees with ajv on each. If the two diverge (a fixture passes ajv but fails pydantic, or vice versa), CI fails — that catches both codegen bugs and silent schema drift.
