How Proofline fixes what it got wrong.

What can never be silently edited

• A published record's numbers. A corrected record is a NEW version; the earlier one keeps its identity and stays inspectable.
• The dataset a record was computed from. It is content-addressed, so changing it changes its hash and the record no longer matches.
• The version of the fill model, fee treatment or settlement logic that produced a result.
• A record's classification. Moving something from limited to verified is itself a recorded change.
• The evidence attached to a market, or the reason it was attached.

A restatement does not overwrite history. The superseded version remains, marked as superseded, with the reason recorded. If a record simply disappeared, that would be indistinguishable from hiding a bad result.

How to report an error

1. 01
   Tell us what is wrong and where

   The page, the record or the market, and what you believe is incorrect. A link and a sentence is enough. You do not need an account.
2. 02
   A person reads it

   Reports are reviewed by hand. There is no automated takedown and no automated correction.
3. 03
   We reproduce it, or explain why we could not

   A record's inputs are sealed, so a disputed number can be recomputed exactly. If the original result stands, you get the reason rather than silence.
4. 04
   The fix is published as a change, not a patch

   A corrected record is issued as a new version with the reason attached, and the superseded version stays visible.

Where to send it

An error on a page or in a record

Use the feedback link in the footer of any page, or SUGGESTION? from here. It carries the page you were on.

A disputed evidence source or classification

Same route. Say which market and which source, and what you believe the correct classification is. See the evidence policy for what each label means.

Something about a verification or a creator's record

Use the verification contact route and say it is about an existing record.

A security problem

Report it privately through the support page rather than in public. Please do not test against other people's accounts.
