Musterlane

Marketplace operators may route jobs to independent contractors that each keep their own field-service system of record. The supplied research confirms integration-broker analogues and a newer stateless authorization pattern, but reports no construction-specific product for many independent grantors serving one operator. It also says the target interfaces referenced by the invention are not verified.

Musterlane creates a separate connection and policy for every contractor. A grant identifies contractor tenant, operator, permitted resources, allowed actions, region, expiry and revocation state. The operator can prepare a dispatch or request status, but write actions pass explicit policy, idempotency and—where configured—human approval before reaching the contractor's system.

Authentication proves possession of a credential, not authority for any arbitrary action. A successful interface response is not proof that a contractor accepted a job, completed work, issued a valid invoice or received payment. Proposed dispatch, provider request, acknowledgment, contractor acceptance, field evidence, invoice and settlement remain distinct.

The first release should support one confirmed system and a read-first workflow for a small contractor network. It must fail closed on revoked or ambiguous grants, isolate every tenant, minimize stored data and never invent write capability from an unverified interface.
