# NavSea Source Layer Consumption Table

用途：汇总当前交付体系中每个 `source-layer` 的全量 feature 数，以及当前 [navsea.json](/home/wwwroot/newpec/navsea.json) 里哪些 style layer 正在消费它。

统计口径：

- feature 数来自 `pbf_analysis.pbf_relayer_candidates`
- 样式消费关系来自当前 [navsea.json](/home/wwwroot/newpec/navsea.json)
- 仅保留当前交付 `pbf` 与当前样式实际使用的 `37` 个 `source-layer`

说明：

- 上表里的 `feature_count = 0`，表示当前 `pbf_relayer_candidates` 全量统计里没有对应记录，但在唐津 AOI 测试瓦片中这些 layer 仍然实际存在并已被样式消费。
- 当前 [navsea.json](/home/wwwroot/newpec/navsea.json) 对这 `37` 个 `source-layer` 都已经有覆盖，不存在“数据里有 layer 但样式完全不消费”的情况。
