Observed fact
The retained prices, coverage state and calculated movement are reported first, and are not revised to fit a story.
Research and sources
Movement first, explanation second.
A price movement is measured before anyone goes looking for a reason, and a reason is never inferred from whichever headline happened to be nearby. Timing alone does not prove causation, and nothing on this site claims otherwise.
Where the research stands
No event-line data is public yet.
Private candidate movement and source records are withheld with the numerical series. No counts, URLs or derived claims are exposed by this page.
Editorial boundary
Evidence can support a claim. It cannot create the number.
Possible explanation
Primary announcements and credible reporting are tested against timing and scope before a marker is placed.
Counterevidence
Alternative causes and contradictory reporting are retained rather than tidied away, including supporting and contradictory evidence for the same move.
Credit
The work belongs to whoever did it.
Every marker names the article, its author — or states plainly that the publisher named none — and the publisher, and links to the original. No article body is quoted and no images are reproduced. If you want to know what a source said, the link takes you to the people who said it.
- 01Detect
A replayable retail movement or coverage anomaly appears first.
- 02Investigate
Search primary announcements, credible reporting and counterevidence.
- 03Separate
Facts, temporal association and contributory hypotheses receive different labels.
- 04Review
A person approves the exact record and its causal wording before a marker exists at all.
How a marker is placed, and what it is not allowed to say.
