Material errors are recorded—not quietly overwritten.

Identify the page, field or statement, explain the claimed issue, provide a primary supporting source where possible, and include the date observed. Do not send personal information or confidential quote text that is unnecessary to assess the issue.

The publisher preserves the prior wording and evidence, records the challenge, checks the relevant source and publishes either a corrected version or a dated reason for no change. A material method change receives a new version instead of silently altering historical decision logic.

High-impact errors that could change a user’s interpretation of cost scope or method availability are reviewed first. The public change log records the date, affected page, material change and method consequence. Send factual reports to corrections@eprpriceatlas.com.
