Catalog data-build slot

Vendor-neutral catalog-domain slot. Drop-in under pack slots/ (already discovered; no extra slot_roots / marketplace path).
slot.yaml is the scene config. More specific entities (limited / credit) are listed before generic product.
Executors talk to DATA_BUILD_API_BASE (default local mock on port 8765). The case pipeline binds these executors from slot.yaml without an LLM when the match is unique.

Single-step routing

User intent	Executor
Standard catalog product	scripts/executors/create_product.ts
Limited catalog product	scripts/executors/create_limited_product.ts
Catalog order	scripts/executors/create_order.ts
Account credit on a product / user	scripts/executors/setup_account_credit.ts

Do not invent productId / userId when the user already supplied them. Optional fields use executor defaults.

node scripts/executors/create_product.ts --json '{"name":"Northwind Standard","city":"demo-city"}'

Scene orchestration

credit-ready-product

1. Create catalog product (or reuse productId)
2. Enroll the product and user in account credit
3. Return productId, enrollment result, creditBalance

bookable-order

1. Ensure a product exists
2. Create an order for userId + productId
3. Return productId, orderId, status

Pass upstream data fields into the next executor. Do not skip a later scene step.

Guardrails

• Start node ../mock_server.ts if no enterprise gateway is configured
• Do not invent productId / userId / orderId
• Defaults: city=demo-city, validHours=4, fulfillOn=today+2days, quantity=1, credits=1000
• See references/tools-guide.md and ../SLOT_SPEC.md
