Verification & integrity

Verification method

Verified metrics are computed by TrueSignal from the business's connected systems through a read-only connection, with access authorized by the business. Public-registry facts are checked against the issuing authority, and credential or registration facts may be confirmed from documents obtained and reviewed by TrueSignal. Any verified figure can be reproduced by a party holding the underlying source data, because that is where it came from.

What Verified means, specifically

Each verified claim was confirmed:

connected_systemComputed from an authenticated, read-only connection to the business's operating system — field management, practice management, or accounting.
public_registryChecked against a public registry, government filing, or licensing authority, such as a state contractor board or the NPPES registry.
document_reviewConfirmed from a document obtained and reviewed by TrueSignal, such as a certification certificate. Reserved for durable facts, re-reviewed on renewal.
derivedComputed from other verified claims on the same record, using a published formula.

Anti-gaming

All data within the verified coverage window is included in every calculation. Values cannot be selectively excluded, edited, or inflated by the business. Manually reported figures are not accepted as verified; declarations are published only under the Attested tier and labeled as such. A metric that cannot be supported by the declared data is omitted rather than estimated, and a computable metric is never withheld because its value is unfavorable.

Versioning & closed periods

Each refresh produces a versioned record with a distinct timestamp, and prior versions remain independently referenceable. Once a measurement window closes, its values are pinned; a later declaration or recomputation that disagrees with a prior one is flagged and noted rather than silently overwritten.

Corrections

Verified metrics are corrected by reconnecting or reconciling the source system; attested fields are corrected through documented submission. The process preserves the record's integrity and does not allow a business to edit unfavorable data.
