CAPABILITY FAMILY / 01
Signature features & reference variation
Measure visual relationships using multiple comparison signals, then account for the natural variation among known specimens.
Descriptive similarityIndependent distanceCombined evidential weight
Scope & interpretationA comparison score is not automatically an authenticity probability. Some workflows require at least two known references.

Measured handwriting & common authorship
Evaluate writing geometry and spacing, rank supplied candidates and express measured support under competing authorship propositions.
Letterforms & spacingCandidate rankingLikelihood ratios
Scope & interpretationEvidential strength depends on the comparison population. Candidate ranking always returns a nearest candidate, even when the true writer is absent.

Structured, evidence-led interpretation
Assess image quality, describe each specimen independently, compare features systematically and consider plausible alternative explanations.
Independent descriptionsEvidence tablesCompeting hypotheses
Scope & interpretationThe explanation must state agreement or disagreement with the measured output. It does not invent percentages.

Regions, geometry & captured detail
Extract candidate marks, inspect duplication and shadows, examine compression history and enhance existing captured signals.
Candidate extractionRegion diagnosticsNon-generative enhancement
Scope & interpretationInput format and capture conditions matter. Enhancement cannot invent missing physical signals, and screening maps are not automatic findings.

Metadata, file records & signed credentials
Read technical records and assess file integrity and signed provenance using deterministic checks.
Metadata inconsistenciesCryptographic fingerprintsContent Credentials
Scope & interpretationMissing or editable metadata can be inconclusive. A verified manifest supports provenance within its scope, not the truth of everything depicted.

Speech, continuity & frame evidence
Transcribe with word-level uncertainty, compare recording content and voices, inspect discontinuities and review sampled video frames.
Confidence-marked transcriptsContinuity indicatorsFrame-level review
Scope & interpretationRaw voice scores and sampled manipulation indicators are diagnostic. The output records original sources, sampled coverage and release status.
