hanzo-research 0.2.0: every research and arena route, the crate's records, provenance

Browse Source 
The Python client now reaches what the Rust crate does and the server
serves. Research covers every /v1/research route: record() files
benchmarks, studies, runs and papers in one batch a kind; runs(),
get_run() and compare() read them; grant(), revise() and retract() move
consent and versions; the experiment plane and artifacts as before.
Arena covers /v1/benchmark: catalog, leaderboard, claims (written with
protocol and source), history, compare, presets, and runs, which queue a
paid execution and are refused without confirm=True.

wire holds the crate's Run, Benchmark, Measure, Study, Paper and
Comparison field for field; canonical writes RFC 8785 bytes equal to the
crate's (tests/vectors/rust.json, written by the crate); lineage and wal
are the crate's records, and a WAL the crate wrote verifies here.
capture() reads the harness commit (the diff's SHA-256 when dirty), the
weights' SHA-256, host, CPU, GPU, device, dtype and packages, and
apply() folds them into a run.

runs(org=) sends no credential: the server answers ?org= only to a
caller with no org. An org the token does not belong to is refused
before the request, since the server would act in the home org. The
command is hanzo-research; the native CLI owns `hanzo`.

# hanzo-research
Record and query Hanzo R&D evidence in one import. The ONE way every producer
(enso-bench benchmarks, hanzo-engine/hanzo-ml kernel-perf, any research project) files
runs into the unified `/v1/research` plane (HIP-0512) — versioned, append-only,
idempotent by content, private by default.
File a measurement made in Python to Hanzo's research plane (`/v1/research`) and its
benchmark arena (`/v1/benchmark`), with what it takes to believe or repeat it: the
harness commit, the model and its weights' SHA-256, the host, CPU and GPU, the device and
dtype, the Python and package versions, the date. The Python peer of the Rust crate
`hanzo-research` (hanzoai/ml): the same wire records, the same RFC 8785 digests, the same
lineage and WAL records. Standard library only.
```python
import hanzo_research as research
# get/create the experiment; provenance is auto-captured (see below)
exp = research.experiment("benchmark", "grok-4.5", "gpqa_diamond")
exp.record("q1", "grok-4.5", {"answer": "A", "correct": True}) # an attempt, idempotent
exp.snapshot(png_bytes) # a board-snapshot artifact
exp.report(markdown_text) # a generated-report artifact
exp.finish(value=94.3) # seal the run
rows = research.query(project="enso-bench", kind="benchmark") # read canonical
```bash
pip install hanzo-research # or: uv run --with hanzo-research python measure.py
```
## Benchmarks, runs, studies, papers
The credential is `HANZO_API_KEY`, else what `hanzo auth token` prints (a CLI token is
fetched again when it expires). Records land in the token's org (its `owner`) and project
(its `project` claim, else `default`). `Research(org="lux")` acts in another org the
token belongs to (`X-Org-Id`); an org it does not belong to is refused before any request,
since the server would file under the home org instead.
The record hanzo.ai/benchmarks draws from. A benchmark defines what is measured; a run
is one execution with its measures; a study is the question runs answer; a paper cites
runs. Each write is a batch, versioned and idempotent by content.
## Worked example
Measure something, file it with its provenance, make it public, read it back.
```python
research.record(
benchmarks=[{"id": "enso.route", "title": "...", "metric": "route_p50_us"}],
runs=[{"id": "enso.route-dgx", "benchmark": "enso.route", "system": "enso",
"measures": [{"category": "route", "metric": "route_p50_us", "value": 12.576}],
"visibility": "public", "canonical": True}],
import hashlib
import platform
import time
from hanzo_research import Benchmark, Research, Run, Split, capture, now
r = Research()
bench = Benchmark(
id="demo.sha256",
title="SHA-256 over 16 MiB",
splits=[Split("16mib", 30, "30 hashes of 16 MiB of zeros, one process, after one discarded")],
metric="p50_ms",
metrics=["p50_ms", "p95_ms", "mb_s"],
)
research.runs(benchmark="enso.route") # yours
research.runs(benchmark="mcp.injection", org="hanzo") # another org's public runs
research.compare("run-a", "run-b") # side by side, with what stops it
p = capture(device="cpu") # harness commit, host, CPU, GPU, Python, packages, date
start = now()
data = bytes(16 << 20)
hashlib.sha256(data).digest()
ms = []
for _ in range(30):
t = time.perf_counter()
hashlib.sha256(data).digest()
ms.append(1000 * (time.perf_counter() - t))
ms.sort()
run = Run(
id=f"demo.sha256-16mib-cpu-{p.host}",
benchmark=bench.id,
split="16mib",
system="hashlib",
version=platform.python_version(),
questions=30,
answered=30,
when=start,
ended=now(),
)
run.put("all", "p50_ms", ms[14], n=30, of=30)
run.put("all", "p95_ms", ms[28], n=30, of=30)
run.put("all", "mb_s", 16 / (ms[14] / 1000))
p.apply(run) # fills commit and by, appends the provenance sentence and its digest to notes
r.record(benchmarks=[bench], runs=[run]) # the definition, then the run: both private
r.grant(run.id, visibility="public", publishable=True)
back = r.get_run(run.id, org=r.org) # the public read: no credential
print(back.completion, back.measure("all", "p50_ms").value, back.commit)
```
## Zero-config auto-instrumentation
`completion` is the server's: `complete` only when `answered == questions` and `ended` is
set; `partial`, `inconsistent` or `unknown` otherwise. A model run names its weights:
`capture(model="kai-1.3", weights="/models/kai-1.3", device="cuda", dtype="bf16")` hashes a
file, or a directory by its `SHA256SUMS` (else every file under it), and `apply` sets
`system` to the model and `version` to `<model>@<sha256>`. A dirty harness tree is recorded
with the SHA-256 of `git diff HEAD` and the untracked files, so the number stays pinned to
the code that made it.
The caller supplies **no** provenance. On `experiment()` the SDK reads the run's
environment and captures three self-documenting narrative sources, plus machine context:
## The research plane: `Research`
- **the calling code's docstring** — *what this experiment is* (write a normal module
docstring);
- **the commit messages since this experiment's last recorded run** — *what changed +
why* (commit normally);
- an optional **`note=`** you pass.
| call | route |
|---|---|
| `record(benchmarks=, studies=, runs=, papers=)` | `POST /v1/research/{benchmarks,studies,runs,papers}`, one batch a non-empty kind, in that order: `{"runs": [...]}` |
| `benchmarks(id=, project=)`, `get_benchmark(id)` | `GET /v1/research/benchmarks` |
| `runs(id=, benchmark=, system=, study=, completion=, since=, until=, project=)` | `GET /v1/research/runs`: your org's runs, private ones included, with the completion census and the fields runs leave unstated |
| `runs(org=...)`, `get_run(id, org=...)` | the same route with `?org=` and no credential: that org's public runs |
| `studies(...)`, `papers(..., cites=)` | `GET /v1/research/{studies,papers}` |
| `compare(a, b)` | `GET /v1/research/compare`: the reasons the two runs may not be compared, the config they differ in, the deltas |
| `grant(id, visibility=, publishable=, trainable=)`, `grant(sha256=, visibility=)` | `POST /v1/research/grants`: on every version of the id; a write is always private until this |
| `revise(record)` | a new version marked `corrected` |
| `retract(id, why)` | a new version marked `retracted`: the id leaves every listing, earlier versions stay |
| `ingest`, `query`, `totals`, `projects`, `experiment(...)` | the experiment plane: `/v1/research/{experiments,totals,projects}` |
| `upload_artifact`, `upload_json_artifact`, `artifacts`, `get_artifact` | `/v1/research/artifacts[/<sha256>]`: `snapshot` or `report` bytes, addressed by the server's hash |
| `url(run_id, org=)` | the public read address of one run: the `source` a claim cites |
Plus `git_sha` / `git_branch` / `git_dirty`, `lib_versions`, and host. The project
self-documents as a side effect of running.
Every write is a batch of at most 20,000 and is idempotent by content: the same record
again records nothing. A mapping is sent as given; a `Run` is sent with every field. A
refusal raises `Denied` (401, 403), `Missing` (404), `Invalid` (400, 409, 422), `Limited`
(413, 429) or `Unavailable` (502 to 504, no answer), each carrying the server's own
sentence; a 503 is asked again after 2, 4 and 8 seconds. A NaN or infinity never leaves:
`json` refuses it before the request.
## Importer-agnostic, idempotent
## The arena: `Arena` (or `Research().arena`)
`ingest(experiments=…, attempts=…)` is one idempotent POST. Any source — a SQLite
backfill, git history, a kernel-perf campaign — maps its records to stable ids and calls
it; re-import is a no-op. "Load all research in" is just running importers.
| call | route |
|---|---|
| `catalog()` | `GET /v1/benchmark/catalog` |
| `leaderboard(benchmark)` | `GET /v1/benchmark/leaderboard`: each model's measured score (its latest run) beside a published claim. Only claims a SuperAdmin wrote under org `admin`, and public, reach it. |
| `claims(benchmark=, model=, provider=, source=, protocol=, org=)` | `GET /v1/benchmark/claims`: every org's public claims, labelled, and your org's private ones |
| `post_claims(rows, visibility=)` | `POST /v1/benchmark/claims`: under your acting org; each row names its `protocol` and its `source` (for a measured score, `Research.url(run_id)`), or it is refused here |
| `history(benchmark, model=)`, `compare(a, b, benchmark=)` | `GET /v1/benchmark/{history,compare}`: read the arena's per-item attempts plane, not the research runs |
| `presets()`, `post_preset(preset)` | `GET/POST /v1/benchmark/presets`: validated and echoed as `enso-<name>`, not stored |
| `post_run(benchmarks, model=, endpoint=, confirm=True)` | `POST /v1/benchmark/runs`: queues a paid execution, so it is refused without `confirm=True` |
## Config
## The command
`RESEARCH_BASE` (default `https://api.hanzo.ai`), `HANZO_API_KEY` (per-org key →
Bearer), `RESEARCH_PROJECT`. Uploads are private; public visibility, training, and
commons rights are each a separate grant. Stdlib only (urllib) — importable in any
zero-dep harness.
`hanzo-research` (or `python -m hanzo_research`); every answer is JSON on stdout.
```bash
hanzo-research post runs.jsonl --grant public --publishable # a run per line
hanzo-research post plan.json # {"benchmarks": [...], "runs": [...]}
hanzo-research post plan.json --dry # print the bodies, file nothing
hanzo-research list runs --benchmark demo.sha256
hanzo-research list runs --org hanzo # hanzo's public runs, no credential
hanzo-research get demo.sha256-16mib-cpu-dgx --org hanzo
hanzo-research grant RUN_ID ... --visibility public --publishable
hanzo-research retract RUN_ID --why "read on the wrong split"
hanzo-research compare RUN_A RUN_B
hanzo-research provenance --model kai-1.3 --weights /models/kai-1.3 --device cpu
hanzo-research arena leaderboard --benchmark gpqa_diamond
```
It is not `hanzo research`: the `hanzo` command is the native CLI, and no Python package
in this workspace may install one.
## Records beside the API
- `canonical.canonicalize(value)`, `canonical.digest(value)`: RFC 8785 bytes and their
SHA-256, equal to the crate's `rfc8785_canonicalize`/`rfc8785_digest` on every string,
integer within 2^53 and float from 1e-6 to 1e21. Past that the crate writes Rust's
`Display` (`1e21` as 22 digits, `-0.0` as `-0`), which is not RFC 8785; this package
writes the RFC's `1e+21` and `0`. `tests/vectors/rust.json` holds the crate's own output.
- `lineage`: `DataPurpose`, `LineagePolicy` (a child never less restrictive than a parent),
`ContaminationError`, `verify_promotion_eligibility`, and the crate's evidence records
(`EnvironmentV1`, `GateSpec`, `Claim`, `TeacherInteraction`, `PairEvidence`,
`DeterminismReport`, `ArtifactRef`, `ResearchEvent`), each with the crate's digest.
- `wal.ResearchWal`: an fsynced, hash-chained event log. A log the crate wrote verifies here
(`wal.verify`), and the reverse.
## Tests
```bash
uv run --no-project --with pytest pytest pkg/hanzo-research # no network
uv run --no-project --with pytest pytest pkg/hanzo-research -m integration # api.hanzo.ai, no credential

"""`Arena`: the `/v1/benchmark` routes hanzo-inc/cloud `apps/benchmark` serves.
Two planes, never blended. The MEASURED plane is per-item attempts the arena's own harness
made; `leaderboard` reads each model's latest run of them, and `history` and `compare`
read every run of them (`compare` pairs two models on the items both answered and gives an
exact McNemar p). The PUBLISHED plane is claims: someone's reported score, each with the
source it was read from.
What reads where:
* `leaderboard` shows, beside the measured score, only claims an org-`admin` SuperAdmin
wrote, and those public. Every other org's claims are at `claims`, labelled with their
org, and never on the board.
* `claims` shows public claims of every org, plus the caller's own org's private ones.
* `post_claims` writes under the caller's acting org, private unless `visibility="public"`.
Writing under org `admin` needs a SuperAdmin token (owner `admin`).
* `post_run` asks the arena to measure a model: a PAID execution, so it is refused here
unless `confirm=True`. The answer is an admission, not a result.
* `post_preset` validates a blend and echoes it as `enso-<name>`; the arena stores nothing.

"""Hanzo Research SDK — the ONE way every producer records and queries research.
"""`Research`: every route hanzo-inc/cloud `apps/research` serves at `/v1/research`.
Generated-shape from the openapi/research contract, wrapped in a tiny, intuitive,
ZERO-CONFIG surface so hand-rolling is obviously the worse choice:
Two planes on one client. The RECORD plane names what a number needs to be believed:
benchmarks (the task), runs (the execution, its completion derived by the server),
studies (the question) and papers (the writing that cites runs). The EXPERIMENT plane is
the older stream of one measured number per id plus its attempts and diary artifacts; the
`experiment()` handle files to it.
import hanzo_research as research
# A benchmark run — accumulate attempts, seal with the score.
exp = research.experiment("benchmark", "grok-4.5", "gpqa_diamond") # get/create → handle
exp.record("q1", "grok-4.5", {"answer": "A", "correct": True}) # an attempt, idempotent
exp.snapshot(png_bytes) # a board snapshot artifact
exp.finish(value=94.3) # seal the run (or use `with`)
# A kernel-perf run structured as a falsifiable test — state the claim, log what you
# see, then PROVE or REFUTE it. A refutation is a first-class, durable result.
k = research.experiment("kernel-perf", "matvec_q4k_f32_blk", "vulkan/6144x2048",
metric="ratio_vs_hand",
hypothesis="the DSL f32-direct matvec beats the hand kernel",
predict="DSL/hand >= 1.0 cold in-engine at the dominant FFN shape")

k.conclude("proven", because="1.022x at 6144 rows (loses small shapes → gate >=4096)",
value=1.022) # git sha + lib versions auto-stamped
rows = research.query(project="enso-bench", kind="benchmark") # read canonical
Auto-instrumentation (the caller supplies NO provenance): on experiment()/finish() the
SDK reads git sha/branch/dirty, the commit messages SINCE the last recorded run of this
experiment (the narrative of what changed), the installed lib versions, and the host —
and weaves them into the record. Research self-documents as a side effect of running.
Auth is the per-org key (private-by-default is enforced server-side). Records mirror to
the cloud /v1/research surface (HIP-0512), which is versioned + append-only + idempotent
by content, so re-recording the same result is a no-op.
Everything a caller writes lands private, under the caller's org, in the token's project.
Visibility (private, org, public) and the training and commons consents are a separate
call, `grant`. Records are versioned and append-only: a correction is a new version under
the same id (`revise`), a withdrawal is a version marked retracted (`retract`), and every
earlier version stays retained.

"""What a filed measurement must carry to be believed or repeated: the harness commit, the model

`capture()` reads all of it from the environment; `Provenance.apply(run)` folds it into a
run: `commit`, `system`, `version` (`<model>@<weights sha256>`), `by`, and a sentence in
`notes` ending in the SHA-256 of the whole record (RFC 8785), so the record can be filed
beside the run as an artifact and checked against it. Best-effort throughout: a missing
tool or a directory outside git yields an empty field, never an error.
The functions the experiment handle uses (`git_state`, `commit_narrative`, `lib_versions`,
`host`, `find_repo`, `caller_doc`) are the crate's `provenance.rs`, record for record.
