Overview & Vision + +Each SCIBASE project repository functions as a **unified research container** combining the collaborative code-review power of GitHub, the interactive execution of Jupyter workspaces, and the academic rigor of scientific preprints. + +It bundles: +* **Manuscripts:** Dynamic Markdown / LaTeX documents with live computational figures. +* **Datasets:** Multimodal data assets tracked via content-addressed storage (IPFS/DVC). +* **Code & Pipelines:** Production scripts, model architectures, and data transformation steps. +* **Environment Manifests:** Declarative container definitions (Docker, Conda, Nix) guaranteeing 100% computational reproducibility. + +--- + +## 2.

Dual-Layer Version Control Architecture + +Scientific projects deal with both small text files (code, papers) and massive binary assets (gigabyte/terabyte datasets, neural weights).

Reproducibility & Containerized Execution Engine + +To ensure that any researcher in the world can reproduce findings in 1 click: +* **Zero-Setup Cloud Runtime:** Every commit builds an isolated container image using root `env/Dockerfile`. +* **Hardware Binding:** Manifests specify exact GPU compute constraints (CUDA version, VRAM requirements, CPU cores). +* **Deterministic Seeds:** Runtime injection of global PRNG seeds across PyTorch, TensorFlow, and NumPy. + +--- + +## 5.
