Each day, an improvement relevant to most Codex / Work users — or a full reset.
We record source-linked announcements. No confirmed result means unconfirmed, not a broken promise.
Days run midnight to midnight in Los Angeles. This is our tracking convention, not an official schedule. Your time zone only changes displayed times.
Votes measure whether an improvement helped the community. They never rewrite the announcement record. Anonymous voting limits browsers, not people.
