SLM-in-SciPaper
Evidence-grounded scientific paper analysis, from an NLP pipeline to local browser inference with ONNX.
Agentic Observer workbench
A local desktop workbench for GOSIM Agentic Observer public practice scenarios.
Also exploring coding-agent collaboration (experimental) and scene representations & test-time adaptation (research archive).
I contribute focused bug fixes and regression tests. A few merged examples:
- simplejson — read UTF-8 files correctly in the command-line tool.
- pyee — handle cancelled executor futures in completion callbacks.
- TypeScript JMESPath — keep empty strided slices empty.
