When uncertainty is still ordinary trial-start friction
Early uncertainty is still more ordinary when your team is clarifying who should join the trial, checking basic setup expectations, or deciding how to begin evaluation without yet changing a real readiness or start-now decision.
Ordinary trial-start friction can be inconvenient, but it does not automatically mean the church is unready, the path is unsafe, or the evaluation has already been disproven.
When uncertainty becomes a real blocker
Treat early uncertainty as a real blocker when it starts weakening confidence that the church should start now, changing who needs to align before proceeding, or making the consequence of guessing too high to keep treating the issue as normal startup friction.
At that point the safer move is narrower review and clearer consequence handling, not more optimism or vague reassurance that the uncertainty will probably sort itself out.
