Subject: p70: 启动帧率与渲染基准（真实可复跑数据）
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- scripts/bench-p70.sh：两档基准——Kernel --performance-baseline（6000 tick ×3）
  + Desktop xvfb 60s 真实帧循环；scripts/analyze-p70.py 汇总裁决
- Game.fs：LV_FRAME_LOG=1 逐帧日志（墙钟帧间隔 + GC 线程分配增量 + tick/panel），
  仅新增日志，不改渲染/更新逻辑
- P70PerformanceBaselineTests：Pin --performance-baseline final_digest=953775FA…（防漂移）
- 实测：Kernel tps mean=466679 alloc=3032184 gen0/1/2=0/0/0 determinism=PASS；
  Desktop 60s frames=8788 fps=139.3 mean=7.179ms max=33.919ms 掉帧>33.3ms=2
  每帧分配 mean=231KB p95=297KB；dotnet-counters 缺席已如实标注
- Desktop 338/338、Kernel 120/120；Kernel/Sim/渲染口径/字形表未动

+# P70：启动帧率与渲染绘制概要基准（真实可复跑，不宣称未测性能）。
+#
+# 两档：
+#   * Kernel 吞吐：Headless `--performance-baseline`（6000 measure tick ×3，已有入口），落 kernel-baseline.txt。
+#   * Desktop 渲染帧：xvfb 真实帧循环 N 秒（默认 60），逐帧打印墙钟帧间隔与线程分配增量
+#     （LV_FRAME_LOG=1，仅新增日志、不改渲染逻辑），落 desktop-log.txt。
+# 之后由 scripts/analyze-p70.py 汇总裁决到 docs/evidence/p70-analysis.txt。
+#
+# 用法：bash scripts/bench-p70.sh [out-dir]   （out-dir 默认 /tmp/opencode/lv-p70）
+# 环境：P70_SECONDS（默认 60）基准秒数；P70_FORCE=1 允许 fps=0 时仍返回 0。
