Statement
Explicit stop rules and red teams counter sunk-cost escalation and megaproject hype.
Evidence dimensions
- Basis
- proposed
- Readiness
- operational
- Confidence
- supported
Assessment rationale
Lifecycle decision analysis, risk-informed comparison, peer review, and disaster-risk learning support explicit alternatives, reassessment, independent challenge, and documented stop conditions. Their effect on sunk-cost escalation in a generation-ship program remains unmeasured.

Assumptions and limits
The assessment applies to this bounded statement and the cited source scopes. A source can support one relationship without validating a generation ship, and an editorial grade does not substitute for independent review or representative demonstration.
What would change this conclusion?
Prospective program evidence showing that published stop rules and independent red teams do not improve cancellation, redirection, risk disclosure, or resistance to sponsor and founder pressure would weaken this claim.
