四大版图:生命周期五阶段 × 双轨制(一人公司轨道 vs VC 轨道,每阶段标注谁占优、VC 看什么)、死法图鉴(15 种死法,按阶段与「AI 能救/部分能救/救不了」筛选——比成功学稀缺且可信)、资本集中度面板、中美对照与硬骨头。★=该格领跑者。 Four maps: the five-stage lifecycle × dual track (solo track vs VC track, with who wins each stage and what VCs look for), the death catalog (15 ways to die, filterable by stage and by whether AI can save you — rarer and more honest than success porn), the capital-concentration panel, and the US–China comparison with the hard bones. ★ = the leader of that box.
