Editorial, review and correction policy
Make the basis of every resource visible.
Version 1.0 ·18 September 2026 · Original educational case
Ownership and independence
Content owner: Islam Ali Hassanin. This is an independent personal educational platform. Referenced institutions are sources, not sponsors or endorsers. Credentials do not replace review of a specific model.
Publication checklist
Define the question, sources, scope and assumptions. Check arithmetic against an independent example and test blank, zero, negative-result and boundary cases. Review bilingual meaning, mobile layout and downloads. Disclose external technical review status.
Version and review triggers
Each model has a version, date and limits. Material formula or scope changes require a new version and change note. Review is triggered by a supported error report, relevant source change or planned review date. This is a manual editorial workflow, not continuous automatic monitoring.
Report an issue
Use LinkedIn with the page URL, version, expected and observed results and non-confidential reproduction steps. Do not send client records or sensitive financial data.
Correction procedure
Log evidence; reproduce and assess materiality; pause a materially misleading model if needed; correct and retest; publish a version with the issue and impact recorded. Separate unverified suggestions from confirmed defects. Response times are not guaranteed.
