SUMMARY: Source rotation is the scheduled review of which sources a system surfaces, trusts, cites, and repeats.
Any stable source mix becomes a worldview. The same outlets, feeds, archives, experts, regions, languages, and ranking defaults slowly define what the system treats as normal evidence.
Rotation does not mean chasing novelty. It means checking whether the current mix still matches the purpose, audience, and risk of the surface where it appears.
Rotation Fields
Coverage: what regions, institutions, communities, and technical domains are represented or missing.
Independence: whether multiple sources truly originate independent evidence or repeat one upstream claim.
Reliability: what correction history, transparency, and sourcing habits the source demonstrates.
Purpose fit: whether the source belongs in headlines, archive context, forum prompts, or background research.
Where to Use It
Use source rotation for headline news, linked references, recurring archive citations, gallery story notes, and forum research prompts. Pair it with the source ladder so repetition does not masquerade as confirmation.
Operator Rule
If a source mix shapes what users notice, it needs periodic review and a record of why it changed.
Field assessment: a source list is a map of attention.
