test/support/golden_harness.dart：pumpGolden（viewport=physical÷dpr/给足高度/ provider 覆盖）+ goldenAcrossThemes（A/B/C 三主题组）。 test/golden/inventory_list_golden_test.dart：库存列表整屏 × 三主题 golden （fake AsyncNotifier 喂 canned 数据 + isReadonly 覆盖 + SP mock），入库作回归闸。 保真目检：shoot 原型 + montage 与 goldens 并排（见 design-distill flutter-golden.md）。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01TSKEiHsvauyxYUW2itzUXX
