Crown & Fluff is a deployed, Muse-powered pet-card company built in ten days. It gives pet owners a premium way to turn their own photos into personalized royal artwork. A customer chooses a world, occasion, greeting, and card design; uploads a pet photo; and completes Stripe checkout. The paid order triggers image creation and digital delivery. Customers can manage their cards in My Workspace, request an included revision, and choose whether an exact finished asset appears in the Royal Gallery. One-, three-, and five-card packs serve different occasions. Five specialized Muse Spark workers run routine business operations. Operations assigns work and closes completed tasks. Studio creates the initial artwork and handles revisions. Customer Care routes requests and resolves service issues. Marketing develops campaigns and publishes to Instagram and X. Finance records payment, fee, and permitted refund activity. Each role receives a bounded task and current business context. A separate Muse Spark verifier examines consequential proposals against independently loaded evidence before an adapter checks current state and carries out an authorized action. Formal financial exceptions receive an authorized operator decision. Muse Image edits the customer's actual pet photo into the chosen royal scene. The production system checks the photo, ties it to the paid card, applies the exact approved greeting, and records the version and hash of the finished artwork. Stripe payment verification starts the per-card workflows; email acceptance and delivery become distinct recorded facts. Gallery sharing is controlled per card and exact asset, so customer permission remains part of the operating decision. The same workforce creates brand campaign art and copy, reviews the intended asset, and records publication outcomes. The Business Recorder makes the company inspectable. It replays original business events on a chronology, draws the causal handoffs between customers, workers, the verifier, and providers, and exposes the underlying receipts. A viewer can distinguish what an AI worker proposed, what the independent verifier approved, and what Stripe, email, or publishing services actually confirmed. The record connects commercial results to the actions that produced them. We measured a controlled 72-hour Stripe TEST run from October 31 to November 3, 2026. It produced 1,329 recorded events, 68 initial card deliveries, 26 paid TEST orders, and 11 revised card deliveries. The ledger contains 263 workforce proposals and 263 independent verifier verdicts. Marketing made three verified operating Instagram publications and one X publication. These are observed TEST outcomes; the customer storefront is deployed separately at cf.kronowave.com. Crown & Fluff solves two connected needs: pet owners receive a premium personalized product, and operators can inspect how an AI workforce creates, delivers, supports, and markets it.
