ectogenesis

Operational membership

Recognition requires an attributed definition and observable inclusion criteria.

1. Who defines ectogenesis this way, and what observable conditions must an instance satisfy? definition
2. Under this definition, where do embryo culture and neonatal intensive care stop and ectogenesis begin? boundary

Coverage and prior gestation

A coverage claim must specify the externally sustained interval and any preceding gestation within a body.

1. Which developmental events define entry into and completion of the claimed external gestation? definition
2. What development occurred within a maternal body before external support began? provenance

Functional support dependencies

Each claimed gestational function needs a documented support arrangement and evidence of its performance.

1. How are gas exchange, nutrient delivery, and waste removal supported in this instance? definition
2. Which observations establish that these arrangements meet the organism's requirements at the recorded developmental stage? measurement

Environmental adequacy

Environmental adequacy must be assessed for the particular organism and developmental interval.

1. Which fluid, thermal, mechanical, endocrine, and infection-control conditions are measured or deliberately maintained? measurement
2. Which normally maternal or placental contributions remain unrepresented or have uncertain substitutes? boundary

Entry state and trajectory

Interpretation of the developmental course depends on the organism's condition before and after external support starts.

1. What developmental stage and physiological condition were documented immediately before and after entry into external support? measurement
2. Which observations distinguish continuing maturation from survival without expected developmental progress? measurement

Transition outcome

The end of external support must be distinguished from demonstrated capacity for the subsequent physiological state.

1. What event ended external gestation, and which support dependencies persisted afterward? boundary
2. What post-transition developmental outcomes were observed, over what follow-up interval? measurement

Demonstrated capability

Each capability claim must be bounded by the species, interval, conditions, and endpoints actually studied.

1. Which accessible study or observation supports the claim, and what exactly was demonstrated? provenance
2. Which claimed capabilities remain proposals rather than observed outcomes? boundary

Bounded extrapolation

Comparative and translational conclusions require explicit justification.

1. Which comparator supports the outcome judgment: in-body gestation, neonatal care, another external support approach, or a justified alternative? measurement
2. What evidence supports extending these results to another species, developmental stage, support duration, or clinical population? boundary

Decision-specific authorization

Consent and authority must be recorded separately for each consequential transition or intervention.

1. Whose consent and authorization are required for transfer into external gestation and for subsequent experimental or clinical interventions? action
2. Who may decide to continue, change, or discontinue external support, and which applicable instruments establish that authority? provenance

Contested classification

Biological description, legal classification, and ethical interpretation must each be attributed rather than treated as interchangeable.

1. How do relevant sources classify the externally developing entity, and which developmental or transfer events do they consider decisive? definition
2. Which competing accounts distinguish ending pregnancy, declining genetic parenthood, and deciding whether external gestation continues? boundary
