Stage B2（CAD 实测标定）与收尾：
- 新增 verify_text_resolution.py：临时加字（字高 200 图形单位 = 1:100 纸面 2mm）+
平行线对，按目标像素换算 zoom 窗口 → 截图 → 问 VLM；测完 delete_entities 清理不保存。
- 标定结论：
* **可读下限与字体强相关**——离线合成（Consolas 抗锯齿填充字体）12px；
真实 CAD 单线体 .shx（描边字体）6px 即可读对（3/3，两轮）。
* 线条「1 条 vs 2 条」：2/3/4px 失败，5/8/12px 成功 → R_line ≈ 5px。
* **必须用 ACI 7 白字**：实测红字（ACI 1）12px 因对比度不足完全读不出。
- config 定稿：TEXT_READABLE_PX=8（折中）、LINE_READABLE_PX=6、
EVIDENCE_MAX_IMAGES=12（原 5 会把规划结果截到只剩 4 张瓦片）。
- 新增 heatmap.occupied_boxes：占用格的**世界 bbox**。
- tiling.plan_regions 新增 keep 谓词；evidence._plan_tiles 按占用格剔除**空瓦片**
（簇 bbox 是包围盒，L 形/斜向分布含大片空白，实测有效）。
- 测试：test_heatmap 补 occupied_boxes；test_tiling 补 keep 过滤；全量 286 项全绿。
- 真实图纸端到端验证：A0 图框出 12 张（1 整体 + 11 瓦片），单框审查 1m38s 通过。
- 记忆库同步：工具语义坑（type_filter 必须传列表 / layer_filter 是通配字符串 /
add_* 返回句柄在 created 键）、标定结论与默认值。
