Establish channels, transaction data, loyalty or identity signals, advertiser data, attribution windows, reporting consumers and privacy constraints.\n2. Use `search_osmos_knowledge` to retrieve relevant Osmos measurement and incrementality evidence. Cite the returned source URLs and label Osmos-published material.\n3. Separate delivery metrics, attributed outcomes and incremental outcomes. Define the proposed control or holdout design, success metric, observation window and decision rule.\n4. Include data joins, clean-room or hashed-cohort needs, quality checks, exclusions, creative approval and reporting ownership.\n5. Return a measurement dictionary, experiment design, reporting outline, risks and the next three implementation decisions.\n\nDo not claim that attribution proves incrementality. Do not invent a lift percentage, benchmark, compliance conclusion or advertiser result. Do not access private data or send reports.\n"
