Workwitness

The research confirms field-photo and mobile-form products, content-provenance standards, signing infrastructure, and improving device support. It found no standard assertion for work performed. Content provenance can describe an image's capture and edit history within scope, but it does not prove who did the work, where the device really was, that the task met specifications, that a customer accepted it, or that payment is due.

Workwitness should create a portable evidence bundle, not an automatic settlement instrument. A paying network must explicitly contract to accept a schema version, evidence class, review process, authority, exceptions, dispute rights, and payment trigger. Device attestation, geolocation, time, asset scan, photos, measurements, technician statement, supervisor review, and customer acknowledgment remain separate observations.

The contractor keeps an export and controls reuse, while customer, occupant, site, and bystander privacy is minimized. A receipt can be corrected or superseded without erasing history. It never becomes a worker-performance score, universal credential, lien waiver, safety certificate, code compliance proof, warranty, or guaranteed payment.

Field-service networks, contractors, insurers, property operators, and marketplaces that need mutually accepted completion evidence and a portable dispute trail.
