Distribution data-build slot

Vendor-neutral distributor slot. Drop-in under pack slots/ (already discovered).
slot.yaml scene ready-to-sell is create distributor → bind inventory → set commission.
Executors talk to DATA_BUILD_API_BASE (default local mock on port 8765). The case pipeline binds from slot.yaml when the match is unique.

Single-step routing

User intent	Executor
Create distributor	scripts/executors/create_distributor.ts
Bind supply / inventory	scripts/executors/bind_inventory.ts
Set commission	scripts/executors/set_commission.ts
Browse and quote	scripts/executors/browse_and_quote.ts

node scripts/executors/create_distributor.ts --json '{"name":"North Channel"}'

Scene: ready-to-sell

This scene depends on a catalog product (another domain's material). If productId is not in context and the catalog slot cannot produce one, ask the user for that product material (reuse an id, or construct via catalog first). Then continue bind → commission. Do not skip those steps.

1. Create distributor → distributorId
2. Bind productId
3. Set commission rate
4. Return distributor, binding, and commission

Optional fields (rate, region) use executor defaults. Do not invent distributorId / productId when the user already supplied them.

Guardrails

• Start node ../mock_server.ts if no enterprise gateway is configured
• Do not invent distributorId / productId
• Defaults: region=domestic, rate=0.1
• See references/tools-guide.md and ../SLOT_SPEC.md
