+TauBench additionally requires Python 3.12 or newer and the upstream `tau2`
+package. Install the pinned revision explicitly before running that benchmark:
+
+```bash
+uv pip install "tau2 @ git+https://github.com/sierra-research/tau2-bench.git@fc0055dc4e0a316c3f83133267fbd6faaa770992"

+OpenJarvis does not install third-party packages automatically when an
+evaluation is imported or run.
+
 !!! note "Python version requirement"
     Python 3.10 requires the `tomli` package for TOML config parsing. `openjarvis` declares it as a conditional dependency, so it is installed automatically.

-| Pure-Rust mining algorithm exposed to Python | `pearl/py-pearl-mining` | The complete `mine()` + `verify_plain_proof()` cycle. CPU-only. Hardware-portable. |
-| PyTorch reference of production NoisyGEMM | `pearl/miner/miner-base/src/miner_base/noisy_gemm.py` | The same NoisyGEMM that vllm-miner accelerates with H100 CUDA. Bit-exact denoising verified by upstream test (`tests/test_noisy_gemm.py:92`). |
-
-So this directory contains:
-
-1. `smoke_test.py` — a runnable script that **actually mines a block on this machine** using the upstream Rust path, demonstrating the v1 architecture works on Apple Silicon (or any platform where `py-pearl-mining` builds).
-2. This README documenting where the reference math lives.
-
-## What this is *not*
-
-This is **not a reimplementation** of NoisyGEMM. The original Spec B planned for that;
-Phase 0 made it unnecessary. If you're tempted to write `noisy_gemm.py` here, stop —
-read `pearl/miner/miner-base/src/miner_base/noisy_gemm.py` instead.
-
-## Setup
-
-You need:
-
-- macOS arm64 (M1/M2/M3/M4) **or** Linux x86_64 / aarch64
-- Python 3.12 (`uv venv --python 3.12 .venv` is the easiest)
-- Rust 1.78+ (any recent toolchain — verified with 1.94 on macOS arm64)
-- The Pearl source tree somewhere on disk
-
-Build the wheel and install it (one-time, ~60 s on a fast Mac, ~5 min on first build):
-
-```bash
-# from the Pearl repo root
-cd py-pearl-mining
-uv pip install maturin
-maturin build --release --interpreter "$(which python)"
-
-# install the resulting wheel
-uv pip install target/wheels/py_pearl_mining-*.whl
-```
-
-Or if Pearl publishes to PyPI in the future:
-
-```bash
-uv pip install py-pearl-mining
-```
-
-## Run the smoke test
-
-```bash
-python smoke_test.py
-```
-
-Actual output on Apple Silicon M2 Max (numbers will vary by hardware and run):
-
-```
-host: macOS-26.4.1-arm64-arm-64bit (arm64)
-python: 3.12.1
-[ok] pearl_mining loaded from <site-packages>/pearl_mining/__init__.py
-[ok] PUBLICDATA_SIZE=164  MERKLE_LEAF_SIZE=1024
-[ok] mine(m=256, n=128, k=1024, rank=32) returned a proof in 0.119 s
-       proof.m=256 proof.n=128 proof.k=1024  noise_rank=32
-       a.row_indices=[177, 185, 241, 249]  bt.row_indices=[80, 81, 88, 89, 112, 113, 120, 121]
-[ok] verify_plain_proof: ok=True ('Mining solution verified successfully', 0.2 ms)
-
-[ok] all checks passed — Pearl mining works on this host
-```
-
-The `a.row_indices` and `bt.row_indices` values above are not constants — they're
-`(offset + ROWS_PATTERN)` and `(offset + COLS_PATTERN)` for whichever offset the
-miner happened to find a jackpot at. The smoke test verifies the *deltas* match
-the configured `PeriodicPattern`, not the absolute values.
-
-If it succeeds, this host can mine Pearl using the OpenJarvis `cpu-pearl` provider
-(see Spec B §13). If it fails, the `[fail]` line tells you which step broke.
-
-## What this proves (and what it doesn't)
-
-**Proves:**
-
-- The Pearl mining algorithm executes correctly on this host's CPU.
-- Generated proofs verify under `verify_plain_proof`. (This is the same check
-  validators run on the inputs to the ZK proof.)
-- The whole stack — `pearl-blake3`, `zk-pow`, `py-pearl-mining` — builds and
-  loads as a native CPython extension.
-
-**Does NOT prove:**
-
-- Network-difficulty hashrate. The smoke test uses
-  `nbits=0x1D2FFFFF` (test difficulty), much easier than mainnet. Real mining
-  expected hashrate on Apple Silicon CPU is several orders of magnitude lower
-  per share — see Spec B §1.5.6.
-- ZK proof generation throughput. The smoke test calls `verify_plain_proof`,
-  not `generate_proof`. Plonky2 STARK proving takes seconds-to-minutes of CPU
-  per block (Spec B Open Q10).
-- That this host can keep up with the network's block production rate.
-
-## When to update this
-
-- When Pearl bumps `py-pearl-mining` API: re-run the smoke test against the
-  new ref pinned in `OpenJarvis/src/openjarvis/mining/_constants.py`.
-- When Pearl publishes a Mac wheel to PyPI: simplify the install instructions
-  above, drop the local `maturin build` step.
-- When Spec B v2 adds the PyTorch-MPS reference path: extend `smoke_test.py`
-  with an MPS path comparison. The `miner-base` reference is already in
-  PyTorch, so the v2 smoke test would be a different test invoking
-  `miner_base.NoisyGemm` and comparing CPU vs MPS outputs for parity.
