"""P68（512×384 整图渲染截图证据）分析：读 headless 离线渲染的整图 PNG + 实跑日志。
判据：
1. 尺寸：PNG 宽高 = 512×scale × 384×scale（scale>=8），日志 `p68-map` 一致。
2. 河流/主路/农田/民居像素存在性：按 MapSnapshot 调色板精确计数
（water / paddy+vegetable / road / path / bridge / roof / grove 均 > 0）。
3. 无纯白/纯黑大块（64x64 全白、24x24 全黑）。
4. missing_glyph_slots=0（本图为纯地图，无 UI 文案帧）。
5. 确定性：日志 `deterministic=true`。
Usage: python3 scripts/analyze-p68.py <record-dir> <out-txt>
Exit 0 pass / 1 fail / 2 usage.
