DELIVERABLE   Assessment   Moat lineage: 2026 #48 · operator stream 2

An engine in this repository produces a bounded artifact from a supplied sample today.

What you buy

A defensible answer for this class of system: Keep the credential in a broker the agent cannot read, and authorise each use against a mandate. The run is bounded and the limits are printed with the result.

A bounded engine run on the buyer's sample: findings, a written report, and a SHA-256 artifact manifest. The manifest is unsigned: it is not a signature and not an attestation.

Price and terms (proposal)

List figure$3,500–$7,500 per review
Indicative band$2,500–$7,500 one-time (engagement)
Lead time5 business days after a signed SOW and sample intake
BuyerMerchants, PSPs and browser vendors

The list figure comes from the individual offer; the band is the line default. Neither is an invoice. Scope is fixed in a one-page SOW before work starts.

Scope

One mandate design or one checkout flow; up to 10 sample carts; refusal and limit checks.

What this offer is not. No customer, partnership, endorsement, certification, patent or third-party audit is claimed. Prices are proposals, not validated rates. DELIVERABLE means a bounded engine run on a sample, not an assessment of a production system. Built by a three-person team.
