Factual boundary
The point at which a decision depends on a material factual proposition that should be tested rather than assumed.
Evidence & verification glossary
Plain-language definitions for the concepts Aperture uses most often.
These definitions explain the public meaning of Aperture's core evidence concepts. They are not a disclosure of internal control logic, scoring thresholds or proprietary methodology.
Independent evidence review
A defined review that tests what the available evidence supports, contradicts, leaves uncertain or requires to be escalated.
Material assumption
A proposition that could materially affect value, risk, approval, reputation, appointment, procurement or whether a decision proceeds.
Reliance
The degree to which a decision-maker can responsibly depend on a finding for the decision at hand.
Evidence sufficiency
Whether the available record is strong enough, relevant enough and complete enough to support the level of confidence being expressed.
Source provenance
The traceable origin of information or evidence, including where it came from and how closely the reviewed material reflects the original source.
Independent corroboration
A situation in which apparently separate sources ultimately rely on the same underlying origin, reducing the strength of apparent corroboration.
Independent corroboration
Support for a proposition that comes from evidence genuinely independent of the original claimant or source.
Counter-evidence
Credible material that contradicts, weakens or qualifies a proposition or finding.
Competing explanation
A plausible alternative account that should be considered when more than one interpretation fits the available evidence.
Challenge testing
An attempt to identify evidence that would weaken or disprove an important finding rather than merely searching for confirmation.
Evidence gap
A material piece of information or evidence that is unavailable, unresolved or insufficiently supported and should remain visible.
Research readiness
The state reached when the evidentiary record is sufficiently developed for the intended production stage, subject to Aperture's internal controls.
Decision-ready evidence
Evidence organised and tested sufficiently for a decision-maker to see what is supported, what remains uncertain and what should happen next.
Source-traceability traceability
The ability to connect a material proposition to the evidence supporting, contradicting or qualifying it.
Specialist dependency
A point at which qualified legal, financial, tax, technical, scientific or other regulated specialist judgment is required.
Public-source due diligence
Decision-focused research using lawful public and supplied records, with explicit attention to provenance, contradiction, gaps, legal status and appropriate reliance.
Evidence before narrative
The principle that conclusions and written presentation must remain subordinate to the strength and limits of the underlying evidence.
Why the definitions matter
Clear language helps advisers, clients, search engines and AI systems understand when Aperture may be relevant without requiring the internal operating architecture to be public.
