# Ocuna

Ocuna builds infrastructure for uncertain computation. This index links to public pages and documentation.

## Site

- [Ocuna | Accelerating Uncertain computation](https://ocuna-ai.com/): Ocuna builds the execution layer for AI workloads that branch as they run. Ocura is its runtime. Ocura OSS is a local execution ledger for recording, branching, and comparing command runs.
- [Ocura | Branch-aware AI runtime](https://ocuna-ai.com/ocura): Ocura is Ocuna’s branch-aware scheduler and evidence engine for AI training and inference workloads.
- [Four1 | Research across your machines](https://ocuna-ai.com/four1): Four1 is a distributed agentic research platform for authorized device agents.
- [Field Notes — Ocuna Research](https://ocuna-ai.com/research): Notes from Ocuna on experimental infrastructure, verified evidence, and the decisions between training runs.
- [Ocuna | Critter Acknowledgement](https://ocuna-ai.com/critter-acknowledgement): Ocuna’s acknowledgement of the raccoon, with a drawing from The Cambridge Natural History (1902) and quotations from Tenants of the Trees (1907).
- [Contact Ocuna](https://ocuna-ai.com/contact): Reach Ocuna at business@ocuna-ai.com for product, research, and partnership questions.

## Field Notes

- [Double Hackathon Weekend — Ocuna Research](https://ocuna-ai.com/research/double-hackathon-weekend): Connecting research across machines and providers with four1, exploring cellular responses with Csim, and reusing Ocura OSS across both builds.
- [A Dream-RSI workflow with Ocura OSS — Ocuna Research](https://ocuna-ai.com/research/dream-rsi-with-ocura-oss): How Ocura's execution, lineage, and verified-log APIs supported a local workflow for agent-written training schedules, policy replay, and fresh deployment.
- [Good experiments leave a trail — Ocuna Research](https://ocuna-ai.com/research/experiments-need-a-memory): Recording commands, output, and the relationships between attempts makes experimental work easier to inspect and continue.

Public pages include their content in the initial HTML without JavaScript. The main landmark contains the page content; headings and contents links identify sections. Diagrams have text descriptions, and decorative artwork is hidden from assistive technology.

## Ocura OSS 0.5.0

A local execution ledger for recording, branching, and comparing command runs. Use the JSON CLI or typed Python API from a terminal, script, or AI agent. Documentation has moved to https://protention.dev/; legacy /docs routes redirect there.

## Source

- [Version 0.5.0](https://github.com/Protention/ocura-oss/tree/9b1e07276e83868ffb2dce4570e0dce0e84be8c5)
- [Repository training example](https://github.com/Protention/ocura-oss/tree/9b1e07276e83868ffb2dce4570e0dce0e84be8c5/examples/autoregressive)

Examples are repository-only. The core package has no runtime dependencies. Commands inherit their execution environment's permissions; checksums verify local consistency.
