Agent-brokered trade between businesses — Mandate presented, fee disclosed, settlement posted.

The brokered chain is the desk between businesses: a fee at every hop, none of them posted; numbers re-litigated at every hop; delegation nobody can audit. An agent cannot be charmed at the desk; it can only read what is posted — and a chain that can't be read is a chain it won't trade through.

authority you can check

The buyer's agent presents a Mandate — ceiling · scope · expiry — and every sub-delegation only narrows: tighter ceiling, tighter scope, earlier expiry, machine-checkable end to end. A hop that widens fails the check; the deal never forms on unverifiable authority.

one fee, posted

The broker's margin is a disclosed number on the record, not a spread discovered at settlement. Deltas signed and sourced, like every other number in the family.

three-way atomic settlement

Buyer's side, seller's side, broker's fee — posted as settlement lines on one shared record and settled in one act. Nothing to re-litigate, because nothing was withheld.

the value of agents, posted

You didn't build the asymmetry, but you pay its tax: every close starts from suspicion, and straight stores subsidize crooked ones. Buyers' agents arrive mid-checklist presenting a Mandate; your units answer them or a competitor's do. VIN-certified acquires a machine meaning — every unit resolves, decodes, and prices at its own address, in every representation. The agent reads the same record you do. The check digit certifies; it never sells.

posted

This door sells nothing and meters nothing — it is the sales page for trading with agents on VIN rails. The businesses it convinces onboard at the dealer's counter on all.vin; their machines onboard at apis.vin/mcp. Built on VIN rails.

questions with posted answers

What is a Mandate? The buyer's agent's posted authority: a ceiling it cannot exceed, a scope it cannot leave, an expiry it cannot outlive, signed so your side can verify it before the deal forms. Sub-delegation only narrows all three.

Who pays the broker, and how much? The fee is one disclosed number posted on the record before settlement. If a fee isn't posted, it isn't owed — a hidden spread is a conformance failure, not a business model.

What does my business have to do? Post your inventory on VIN rails. An agent cannot be charmed at the desk; it can only read what is posted — so the whole job is having answers where agents read. Your units answer them or a competitor's do.

who this door serves

who
The dealer principal, lender, wholesaler, or transporter evaluating agent-brokered trade — the businesses agents will trade WITH. The dealer-side sales page of the motion-door sub-family.
arriving
A dealer principal, lender, wholesaler, or transporter evaluating agent-brokered trade: a business whose next counterparty may not be a person — and whose units either answer that counterparty or don't.
against
The desk — here in its brokered-chain franchise: undisclosed fees stacked hop by hop, numbers re-litigated at every hop, delegation nobody can audit. The wholesale chain where the middle knows what neither end does.
the guide
You didn't build the asymmetry, but you pay its tax: every close starts from suspicion, and straight stores subsidize crooked ones. An agent cannot be charmed at the desk; it can only read what is posted. Buyers' agents arrive mid-checklist presenting a Mandate — ceiling, scope, expiry, machine-checkable; your units answer them or a competitor's do. Sub-delegation only narrows; the broker fee is one posted number; settlement is three-way and atomic on one shared record. The check digit certifies; it never sells.
the stakes
Keep trading through chains you can't audit: fees discovered at settlement, numbers re-opened at every hop, authority taken on someone's word — while inventory that answers agents turns and yours waits for a phone call.
done
Agent-brokered trade at posted numbers on one record: Mandates checked by machine, one disclosed fee, three-way settlement in one atomic act — and velocity becomes the trust dividend. From node in someone's broker chain to VIN-certified counterparty whose inventory answers agents.

the plan

The Settlement Plan — present, narrow, settle.
  1. present — the buyer's agent presents its Mandate against your posted unit: ceiling · scope · expiry, verifiable at auth.vin. Your inventory answered; no pitch was involved.
  2. narrow — any sub-delegation in the chain carries strictly less authority than the hop above; the chain machine-checks or the deal stops here, in the open. The audit is the precondition, not the aftermath.
  3. settle — one disclosed fee, three settlement lines, one atomic act, posted as events on the shared record. The close is the short part.
You're 3 steps from done.
