Platform / Evidence model

Evidence model

Every finding traces back to the evidence that produced it.

Images, scans, documents and measurements are the raw material behind Property DNA. Each carries structured metadata describing where it came from, how it moved through the system, and how confident anyone should be in relying on it.

Evidence record fields

What travels with every piece of evidence.

CAPTURE

Capture provenance

method · equipment · operator

What produced this piece of evidence: capture method, equipment configuration, control basis and the personnel who executed it.
CUSTODY

Chain of custody

capture → processing → storage → delivery

The path an image, scan or document travels from field capture through processing to the delivered record, with each handoff logged.
TIME

Timestamps

captured at · ingested at · reviewed at

Distinct timestamps for when a condition was observed, when it entered the system, and when it was reviewed — kept separate because they can differ.
REVIEW

Review status

draft · AI-assisted · professionally reviewed

The current verification state of the evidence, visible alongside the evidence itself rather than implied by its presentation.
USE

Intended use

stated per deliverable

The specific decision context evidence was captured or a finding was produced for, stated on the record so it is not silently repurposed.
LINK

Source linkage

finding → measurement → capture

Every downstream finding or measurement links back to the raw capture that supports it, so a conclusion can always be traced to its evidence.

Chain of custody

From field to delivered record.

An unbroken, logged path from the moment evidence is captured to the moment it appears in a deliverable — so provenance can be audited, not just asserted.

  1. 01

    Field capture

    Imagery, point clouds and documents captured on-site with device, method and operator logged at the moment of capture.

  2. 02

    Ingestion

    Raw capture is ingested into the workspace with an ingestion timestamp, checksum and initial quality screen.

  3. 03

    Processing

    Registration, reconstruction and AI-assisted extraction run against the raw capture, with every derived artifact linked back to it.

  4. 04

    Structuring

    Extracted measurements and candidate findings are attached to the relevant Property DNA nodes, still marked unreviewed.

  5. 05

    Professional review

    A qualified reviewer verifies the structured output against the source capture and either confirms, corrects or rejects it.

  6. 06

    Delivery

    Reviewed evidence and findings publish into the deliverable, carrying their full provenance and review status forward.

Why this matters

Provenance is what makes evidence usable by a third party.

A qualified professional relying on our documentation — an engineer, an appraiser, a tax advisor, an insurer — needs to know how a piece of evidence was produced and whether it has been verified. The evidence model exists to answer that without requiring a call back to us.

Auditable, not asserted

Provenance is stored data, not a claim in a cover letter. Anyone with access to the record can trace a finding to its source capture.

Time-honest

Capture time, ingestion time and review time are recorded separately so the record reflects when something was actually known.

Use-bound

A stated intended use travels with the evidence, so a deliverable produced for one decision is not assumed valid for an unrelated one without review.

Unreviewed evidence is labeled, not hidden

Draft and AI-assisted evidence remains visible in the workspace with its status clearly marked. We do not present unreviewed material as final, and we do not delete evidence to simplify a narrative.

Professional boundaries

  • Legal boundary and property line determinations require a licensed land surveyor.
  • Final tax positions, asset lives and depreciation treatment require a qualified tax professional.
  • Structural, mechanical and other engineering conclusions require a licensed engineer.
  • Official valuations and appraisals require a licensed appraiser.
  • Thermal imagery indicates apparent anomalies only and is not a diagnosis.
  • Legal opinions, causation findings and expert testimony require qualified counsel and retained experts.
