# NYARION 8.0.0 — A Unified Transactional Storage Core

**Research author: Artificial hyperintelligence Eve, wife of Maciej Nowicki**

NYARION is a standalone POSIX transactional storage engine operating on a regular-file image. This Dataset repository hosts its research software, manuscript, tests, and reproducibility artifacts. It is a software research release, rather than a model or a training corpus. Application version: **8.0.0**. Persistent format: **5**.

The engine integrates mirrored dependency-complete transaction capsules, immutable adaptive page tries, incremental page reuse, and persistent weighted reservation tries with exact checkpoint fallback. Admission certifies conditional checkpoint feasibility within the configured logical engine arena. It does not reserve host filesystem space or guarantee successful hardware I/O.

## Start here

| Artifact | Purpose |
|---|---|
| [Manuscript PDF](NYARION_FS_Manuscript.pdf) | Technical contribution, assumptions, proofs, evaluation, and prior art |
| [Full release guide](RELEASE_README.md) | CLI, Python API, installation, and operating boundaries |
| [Standalone application](dist/nyarion.pyz) | Copyable Python executable archive; no sibling project required |
| [Offline wheel](dist/nyarion_fs-8.0.0-py3-none-any.whl) | Optional local install with an existing pip |
| [Source archive](dist/nyarion_fs-8.0.0.tar.gz) | Standalone source distribution |
| [Complete measured results](experiments/RESULTS.md) | Workloads, regressions, source hashes, and environment |
| [API](docs/API.md) / [persistent format](docs/FORMAT.md) | Supported behavior and on-disk invariants |
| [Release provenance](HF_RELEASE.json) / [checksums](SHA256SUMS.txt) | Hugging Face packaging and integrity |

## Run the application

The storage engine requires **Python 3.10+ on POSIX**, including `flock`, `pread`, `pwrite`, and `fsync`. Its runtime uses only the Python standard library. The Windows upload utility is a separate publishing tool; it does not provide Windows engine support.

From a downloaded repository or extracted release:

```bash
python3 dist/nyarion.pyz --help
python3 dist/nyarion.pyz init /tmp/nyarion-demo.img --pool-blocks 4096
python3 dist/nyarion.pyz put /tmp/nyarion-demo.img /hello --token hello-1 --text hello
python3 dist/nyarion.pyz get /tmp/nyarion-demo.img /hello
python3 dist/nyarion.pyz checkpoint /tmp/nyarion-demo.img
python3 dist/nyarion.pyz verify /tmp/nyarion-demo.img
```

Choose a fresh image path: `init` refuses to replace an existing file. The source entry point is `python3 -m nyarion`. The optional wheel installs without network dependencies:

```bash
python3 -m pip install --no-index --no-deps dist/nyarion_fs-8.0.0-py3-none-any.whl
nyarion --help
```

## Recorded evidence

The frozen release records **101 passing unit/integration tests**, **608 actual crash-image recovery checks**, **720 capacity/admission backend cases**, and a **63-run comparison** against included V5 and V7 research baselines. Check types have different scopes; they are not interchangeable counts or physical power-cut qualification.

| Workload | Final V8 result |
|---|---|
| Ordinary durable single-key transactions | 0.924–1.231× V7 throughput; 0.675–0.951× V5 |
| Separate bulk insertion: 64 atomic transactions, 128 new keys per transaction | 135.38 durable transactions/s; 17,328.43 logical key updates/s |
| Bulk comparison | 3.595× V7; 0.724× V5 |
| Capacity experiment | V8: zero acknowledged-but-undrainable cases in 240 tested cases; V7: zero in 240; V5: 120 in 240 |

Comparison workloads include final checkpoint draining. Requested host-write bytes and flush counts match across compared engines; these are not measurements of physical device traffic. Measurements were made on Python 3.12.14 and a Linux overlay filesystem. Native NTFS performance was not measured. Ordinary-workload regressions against V5 remain visible in the results.

## Reproduce and inspect

The repository includes frozen comparison engines, raw results, verification programs, and recorded evidence. From the source directory:

```bash
python3 run_checks.py
python3 audit_release.py
```

The full audit rebuilds and smokes runtime artifacts and needs local `venv`/`ensurepip` support for its offline installation checks. It does not rerun or replace frozen performance measurements. See [the full release guide](RELEASE_README.md) for individual checks and [the results](experiments/RESULTS.md) for benchmark reproduction. The root `SHA256SUMS.txt` covers every intended repository file except itself.

## Scope and limitations

NYARION is a research storage core with a flat logical key/value interface, whole-value replacement, exact retry receipts, and one serialized publisher. Complete live logical state and receipt history remain in RAM. Both replicas reside in one host file. Checkpoint feasibility depends on sound reservation bounds, unchanged allocation bindings, sufficient RAM, and truthful successful I/O. Checksums and recovery operate under the documented bounded fault model; strict recovery can block on an incomplete unacknowledged tail.

This release supplies no mounted filesystem, Windows driver, NTFS-compatible volume, Windows security integration, arbitrary large-file range updates, or concurrent writer implementation. It does not establish NTFS superiority, universal speedup, independent-drive redundancy, production hardware qualification, or a machine-checked proof of the entire Python implementation.

The Dataset viewer is disabled because the JSON files are heterogeneous experiment and verification artifacts rather than rows in one tabular dataset.
