Qwen 3.6 27B + Opencode: what am i doing wrong?

Despite using high-bit quantization and specialized agents, the model is failing to maintain complex instructions over long-running tasks. This highlights the ongoing 'lost in the middle' and degradation issues found in large context windows even on premium open-source hardware setups.
