Platform investigation
Instagram performance is evidence. The explanation still has to earn support.
WITNESS models eligible Instagram professional-account and media performance as authorized evidence. The system preserves provider eligibility, permissions, reporting limitations, source identity, and uncertainty before using those signals in a Finding.
Investigation patterns
Reach changed. Did audience response change too?
Separate exposure movement from how recipients actually engaged with the work.
Did a format shift change performance?
Compare the current pattern with relevant format, timing, campaign, and historical baselines rather than treating unlike posts as equivalent.
Is the change isolated to Instagram?
Reconcile the pattern with other authorized creator signals to determine whether it is platform-specific or part of a broader audience change.
Is an apparent drop trustworthy?
Keep provider constraints, unavailable metrics, reporting behavior, and Signal Integrity visible before escalating the conclusion.
Professional-account eligibility is part of the evidence boundary.
Instagram access depends on provider account type, permissions, app review, and resource eligibility. WITNESS should preserve those constraints rather than silently treating unavailable evidence as zero or assuming access the provider has not granted.
Cross-platform comparison starts with semantics.
Instagram reach, engagement, and media performance cannot be safely flattened into another platform's metrics simply because labels look similar. WITNESS reconciles definitions and context before combining the evidence.
