Spectral
A flexible JSON/YAML linter for creating automated style guides
An open-source API style guide enforcer and linter. Why write API Style Guides as lengthy manifestos when you could automate them? Make sure APIs are secure, consistent, and useful. Spectral is open-source but is also baked into Stoplight, with extensions for VS Code and other integration options, giving you real-time feedback wherever you design APIs. Spectral can be used as a generic ruleset engine on any JSON or YAML data but was built with OpenAPI, AsyncAPI, and JSON Schema in mind. Use Spectral rules to target API descriptions for quality improvement or enforce API Style Guide rules, such as naming conventions for OpenAPI models or prohibiting integers in URLs. -

reverse-SynthID
Reverse engineering Gemini's SynthID detection
Reverse-SynthID is a research-focused project that analyzes and reverse-engineers Google’s SynthID watermarking system used in AI-generated images. It leverages signal processing and spectral analysis techniques to identify hidden watermark patterns without access to proprietary encoding methods. The project introduces a multi-resolution “SpectralCodebook” that maps watermark characteristics across different image sizes. Using this approach, it can detect SynthID watermarks with high accuracy and selectively reduce or remove them through frequency-domain manipulation. ... -

__Yang-Mills
A Rigorous Self-contained Native Mass Gap Derivation
Through the enforcement of a global Bakry-Émery curvature-dimension condition, we derive an associated Logarithmic Sobolev Inequality, proving the existence of a strict spectral mass gap. Furthermore, we demonstrate that the geometric boundaries of the effective action induce complex conjugate pole structures in coloured sectors, which—when evaluated through Osterwalder-Schrader reflection positivity and Krein space quotienting—provide a rigorous, first-principles proof of colour confinement. This framework satisfies all Osterwalder-Schrader axioms, offering a fully consistent bridge between Euclidean path integral formulations and physical Lorentzian quantum field theory. -
