Reference state
Know what “normal” means before calling something a change.
A creator baseline is a historical or contextual reference state used to decide whether a current signal represents ordinary variance, a lifecycle pattern, or a material change.
One universal baseline is rarely enough.
A creator may need different reference states for release week versus catalog week, short-form versus long-form content, new audiences versus returning audiences, organic versus campaign periods, or different platforms and formats.
Useful baseline dimensions
Historical
What range has this signal occupied over comparable prior periods?
Lifecycle
What is normal for this stage of a release, campaign, or content cycle?
Format
Does the creator's normal pattern differ by format, duration, topic, or platform?
Audience segment
Do discovery and returning audiences behave differently enough to need separate reference states?
Source mix
Does the normal value depend on the composition of acquisition sources?
Evidence quality
Were prior periods measured under comparable provider definitions and Signal Integrity conditions?
Baselines make proactive intelligence possible.
WITNESS can only say “I noticed something” responsibly if it knows what the creator's expected pattern looks like. Persistent baselines allow Watches to distinguish material novelty from ordinary fluctuation.
