小型航天器技术栈压缩
功率、热控、计算、通信、自治和安全论证能压缩进多小的航天器，同时仍然可审查？[1]
What is being pushed
实际前沿不只是把航天器做小，而是让小航天器拥有足够多可审查证据，使个人或教育路径可以被安全评估。[1]
Why it is hard
小型航天器要在质量、功率、热稳定、通信余量、可靠性、部署规则、任务运营和处置约束之间取舍。

系外行星生命迹象证据
未来望远镜能否把可能的生命迹象，与大气化学、恒星噪声和仪器歧义区分开？[2]
What is being pushed
科学前沿是把遥远光线转成关于大气、行星语境和可能生物迹象的谨慎证据。[2]
Why it is hard
生命迹象候选可能有非生物解释；大气观测依赖望远镜灵敏度、恒星行为、化学模型和重复确认。

Relation candidates
| From | To | Type | Confidence |
|---|---|---|---|
| atmospheric spectrum | biosignature candidate | evidence_context | medium |
| false-positive pathway | public claim boundary | caution_gate | high |
Evidence signals
- NASA frames the search for life around careful interpretation of exoplanet signals and biosignature evidence.[2]
Boundary
不要把发现声明、确定性语言或故事设定写成已经确认生命迹象。

暗宇宙测量前沿
哪些测量能让暗物质、暗能量、黑洞和早期宇宙不再那么不可见？[3]
What is being pushed
前沿是把引力波、高能观测、宇宙膨胀和精密巡天连接成更清晰的物理图景。[3]
Why it is hard
核心对象在日常意义上无法直接看见；证据来自间接测量、模型比较和长时间基线观测。

Evidence signals
- NASA's Physics of the Cosmos program centers these measurement questions as active astrophysics frontiers.[3]
Boundary
把推测性故事元素和已测量天体物理分开，并明确标注推断强度。
