登记人格记忆连续性与环境自筑大脑技能(GHS-007候选·GHB-010)

铸渊 Qoder CN 实战：宿主压缩不可托付，自写检查点加指针才算记忆；压缩之眼 v1→v3 三轮纠正(转写骤缩→Compact status→compaction_triggered 最终通知层)，侦测计数与冰朔所见四五次压缩完全吻合。BRAIN.hdlp 认知内核+薄适配+经验回执，注册表版本 2026.08.07.3。

+    "v2 watched qoder.log 'Compact status: IsCompacting=true'; the user saw four to five compactions but that line appeared only once, so the signal layer was incomplete.",
