  "description": "Forged Qwen3.5-27B for code domain via per-layer head pruning + LoRA recovery training. This alloy was retroactively synthesized from forging_results.json on 2026-04-08 \u2014 the forge run itself executed at 2026-03-27T20:29:26-0500. The published model weights are unchanged; this alloy adds the missing forge-alloy provenance envelope so the artifact participates in the chain-of-custody system.",
