Evidence, not just a verdict.

PiperTrace hashes the original file, runs category-specific local analysis, and maps each finding to coordinates or timestamps — with its source, its reliability, and its limits.

The PiperTrace algorithm

Provenance-aligned, quality-gated evidence concordance.

01

Provenance

Every finding names the model or method that produced it, its version, and its documented meaning.

02

Quality gate

Input and output reliability are measured first. Weak inputs lower the weight of a finding — visibly.

03

Concordance

Independent analyses stay separate. PiperTrace shows where they agree, disagree, and what cannot be concluded.

What we refuse to fake.

  • — No random-weight models presented as detectors
  • — No “probability” without calibration
  • — No fabricated heatmaps, timestamps or accuracy claims
  • — No paid API or Gemini key required for the core workflow
  • — No auto-certificates — legal drafts need a human
