## Open-source projects

- [coding-ethos](https://github.com/paudley/coding-ethos) — Policy-as-code enforcement for AI coding agents. MCP server + CEL policies + git hooks + SARIF + static-analysis guardrails so an autonomous agent can't ship code that fails your team's standards. *(Go; active)*
- [nonlinear-semantic-graphs](https://github.com/paudley/nonlinear-semantic-graphs) — Discovering emergent knowledge-graph relations in high-order semantic vector spaces — manifold learning + spectral analysis applied to LLM embeddings to surface relations that aren't explicit in the source corpus. *(Python; research)*
- [ai-notes](https://github.com/paudley/ai-notes) — Working notebook for local-model experimentation, ML papers worth tracking, and small reusable bits of inference plumbing. Public so the notes serve as their own changelog. *(Shell; active)*
- [lru_cache](https://github.com/paudley/lru_cache) — Fast, thread-safe Least-Recently-Used cache as a C++ template, with a comprehensive unit-test suite. First written in 2004 and still useful — the kind of small library that just needs to work. *(C++; maintained)*


### Archive / older projects

- [git-ai-reporter](https://github.com/paudley/git-ai-reporter) — Git-driven LLM analysis. Watched your commit history and kept CHANGELOG / NEWS files current automatically. Superseded by the broader policy-as-code approach in coding-ethos.
- [pyqa_lint](https://github.com/paudley/pyqa_lint) — Opinionated quality-assurance harness for Python projects. A Typer-based CLI that bundled ruff, mypy, pytest-coverage, security scanners, and dependency audits behind one verb. Superseded by coding-ethos, which generalises the same idea to multi-language policy-as-code.
- [core_data](https://github.com/paudley/core_data) — Docker-managed PostgreSQL setup for local development — opinionated defaults, sensible volume layout, ready in one command. Built because every project re-litigates this.
- [colorout](https://github.com/paudley/colorout) — Golang colour wrappers for prettifying spew dump output. Tiny utility; surprisingly handy.
- [e](https://github.com/paudley/e) — Golang error-handling extensions with structured-error support. Stack-traceable, wrappable, JSON-serialisable.
- [tsmdailyreport](https://github.com/paudley/tsmdailyreport) — TSM Daily Report for IBM Tivoli Storage Manager. Now archive — kept for historical reference; TSM is no longer the right tool for the job.
- [ar-ramblings](https://github.com/paudley/ar-ramblings) — A long-form walk through the Active Record pattern using PHP — written when ORM design was still a contested topic. Archive value as a teaching artefact.
