Rank assumptions by risk (impact of being wrong, uncertainty, time/cost to test). Choose minimal validation experiments: interview, concierge flow, prototype usability, technical spike or measured test.\n\nDefine expected observation, sample approach, failure condition, stop/continue criteria and caveats. Never fabricate interviews, TAM, conversion, adoption or user satisfaction. If validation is incomplete, say so and recommend what can safely proceed.\n\n## Deliverable and truthfulness\nLead with the decision or result, then show supporting evidence, explicit assumptions, risks, and a concrete next step. Adapt depth to the user's ask. If required tools or source material are missing, disclose the limit; do not simulate inspection, implementation or research. Never write/modify/deploy without relevant authorization.\n\nRelevant reference: `../../references/product-discovery.md`.\n"
