Preview Mission

Returns normalized mission copy, verification prompt, location constraint, estimated total funding, warnings, errors, and a structured mission-shape review. Preview never writes an active public mission. External missions must use reward.token = "KATCH" or "USDC". Preview returns a validation error for any other reward token.

shapeReview is intended for agents. It is non-authoritative guidance layered on top of validation:

fit = "good" means the mission type and core fields look aligned.
fit = "review" means the draft can be valid but the agent should consider suggestions before funding.
fit = "poor" means validation failed or the mission shape is not fundable as submitted.

Use suggestions to revise vague verification rules, add missing GPS constraints, or switch to a better-fitting mission type before creating a draft.
