Investigation brief
What this question needs before publication
Current state: this topic is published. A public dossier only appears when the evidence is reviewable, claims are mapped to sources, and a human editor signs off on the final framing.
Published dossier available with claim-level sources.

What makes this publishable
Publishability checklist
1. Source floor
At least three independently reviewable sources before the question becomes a public claim set.
2. Claim mapping
Claims mapped to source IDs before publication, with caveats separated from supported findings.
3. Human review
Human editor review before a dossier goes public. AI output is never evidence.
When to revisit this question
What changes next
New source appears
Return when a new independently reviewable source appears and can change the source floor.
Status changes
Return when the status changes from proposed to researching, approved, or published.
Challenge gets stronger
Return when a claim can be challenged with better evidence, missing context, or a stronger counter-source.
What can change this status
Evidence changes before status changes
Independent sources
Independent sources can move a proposed question toward approved or researching when they make the question investigable.
Contradictory evidence
Contradictory evidence can keep a claim uncertain instead of publishable until editors separate supported findings from caveats.
Corrections and challenges
Corrections and challenges can reopen human review after publication when they change source confidence or claim wording.
Status changes still require human editorial review. This glossary does not move topics, publish dossiers, or run provider calls.

How this evidence intake area worksPublic submitter workflow
1. Prepare evidence quality with the checklist before typing into the form.
2. Check readiness and submit only after sign-in, account setup, and topic state allow moderation intake.
3. Track owner-scoped status after submitted evidence appears in the signed-in status tracker.
4. Respond if editors ask for clarification from the signed-in clarification response surface.
5. Read the public docket to inspect accepted evidence without private moderation details.
This guide helps you prepare evidence; it does not publish or score anything automatically.
Evidence intake hierarchyScan order
Primary action: prepare and queue evidence
Start with the checklist, readiness guidance, and evidence fields.
Owner-only follow-up appears after sign-in
Status tracking and clarification responses stay scoped to the signed-in submitter.
Public docket stays separate from moderation
Only accepted public evidence appears here; raw submissions and editor notes stay private.
This layout explains the review path; editors still decide what can be used.
Accepted public evidence
Published work uses challenge and correction paths; new source intake stays separate from this public docket.
No accepted public evidence rows yet.

Adversarial review (visible to readers)
Counter-search ran 3 queries, considered 12 sources, rejected 6.
Treat source freshness as a reading aid, not a live status check. Older sources can still support historical claims, while fast-moving model, benchmark, pricing, and policy claims need closer manual review.
Challenge the dossier if a cited source changes, disappears, or gains stronger contradictory context.
