Seeking arXiv cs.CL endorsement — TSCG tool-schema compression (13K API calls, 12 models, npm package live)

Hi everyone, I’m an independent researcher (University of Helsinki AI programme) seeking arXiv endorsement for cs.CL (cross-list cs.AI). Endorsement code: I7F9IJ Paper: “TSCG: Token-Context Semantic Grammar for Causal Prompt Optimization in Large Language Models” - ~13,000 API calls across 12 models (4B–32B + 3 frontier) - Phi-4 accuracy recovery: 0% → 90% via format translation - Open-source: npm install @tscg/core (v1.3.0, 8 operators, 47 tests, zero deps) - GitHub: GitHub - SKZL-AI/tscg: TSCG — Deterministic tool-schema compiler for LLM agents. 50-72% token savings, 50 tools in 2.4ms. Phi-4 recovers from 0% to 90% accuracy. 459 tests, zero dependencies, MIT. · GitHub - Targeting EMNLP 2026 via ACL Rolling Review The endorsement takes about 30 seconds. Thank you!
