Corrections
Effective August 14, 2026
Why this page exists
A model that grades itself in public has to be equally public when the grading, the inputs or the published claims were wrong. Corrections are logged here with a date, not quietly patched. If a correction changes a number that was previously published, the entry says so.
Corrections log
What was wrong: When a probable starter could not be matched to a verified pitcher profile, the engine substituted league-average rates and still allowed that projection to be ranked on the Prophet Locks board. Locks published before this date may include starts whose inputs were not pitcher-specific.
What changed: Coverage is now derived from verified identity, real inputs and a known throwing hand. Unverified starters are labelled on the slate and in the console and are excluded from Locks, with the exclusion stated on the board.
What it affected: Prophet Locks boards published before 2026-08-15. Graded results were unaffected — grading always used the real box score.
What was wrong: The app read the shared accuracy record through an authenticated write endpoint, so visitors without a sync key received a 401 and were shown an empty ledger and "baseline" model weights, while /results reported the real record from the same store.
What changed: A read-only aggregate endpoint now hydrates the public record before any trust metric renders.
What it affected: The in-app ledger and weights badge only. The published record at /results was always correct.
How to report a problem
Email hello@pitchprophet.net, or use the contact page. The most useful report names the pitcher, the date, and what you expected to see. Grading disputes are the highest-priority category — the graded record is the one number everything else on this site rests on.
- We reproduce the issue against the stored projection and the box score.
- If the record was wrong, it is corrected and an entry is added here the same day.
- If the record was right, we reply explaining the grading rule that applied. Those rules are documented at /accuracy.
