Paid Media Plan

1. Read the setup profile, business economics, evidence, current account state, and relevant industry template as optional input.
2. Define objective, customer, offer, conversion, value, constraints, geography, regulated category, time horizon, and success criteria.
3. Evaluate channel roles and exclusions from first principles; do not require every supported platform. For a channel outside the twelve-platform contract, load ads/references/additional-platforms.md and return a research lead unless its current buying, eligibility, measurement, and creative evidence is present.
4. Specify campaign architecture, audience strategy, creative system, budget and pacing, measurement, experiments, policy controls, and operating cadence.
5. Phase prerequisites before launch, learning, optimization, and scale.
6. Assign every action an owner, timing, dependency, guardrail, evidence, success measure, and rollback or exit condition.
7. Return canonical JSON and render the requested human plan.

A plan is advisory. It becomes an account change only through launch or optimize mutation gates.
