CUDA backend for rmems/agoge-forger — local LLM fine-tuning and training on the RTX 5080 (Blackwell / sm_120 / ~16 GB VRAM, CUDA 13.3, driver 610.x).

This repo owns GPU kernels and engine CUDA-path measurements. The forge owns the trainer, datasets, and the SFT / QLoRA / post-training ladder. agoge-forger/cuda/ is a stub that points here.

Tagged so far v0.1.0 (M0 closed)
Release target v0.2.0 — measured first-party CUDA operator consumed by Agoge on both MiniCPM5 and Granite 4.1 (docs/RELEASE_V0_2_0.md)
Tip (main) 22cc4f3 — ci: require conditional GPU validation for the v0.2.0 roadmap (#62)
Host ShipOfTheseus · RTX 5080 · ~16 GB GDDR7 · CUDA 13.3

Hard host rules: target sm_120 only (no FA4 / TMEM / MIG); keep ≥ 2 GiB VRAM free before measurement or train; train and GPU CI serialize — never both at once.

Existing smoke tests, telemetry, and synthetic L1/L2/L3 benchmarks are foundations; they do not yet establish the v0.2.0 training-win outcome.
