Content freshness

Freshness has a subject and time horizon: a price may age in a day, technical documentation in months, and a foundational definition much more slowly. A page therefore needs a data-through date, review date, and update trigger rather than one ritual interval.

Publication date marks the first release, modified date a material revision, and a review log the fact of checking. Freshness is not publishing frequency and does not require rewriting stable text merely to obtain a new timestamp.

If OpenAI changes its crawler list or purposes, the platform profile should update the affected fact, source, date, and correction history. If a monthly review finds no change, the article's visible modification date should stay the same.

Connect each unstable claim to a primary source and an update trigger. When a source hash changes, compare meaning rather than navigation or banners; revise affected passages, rerun RU/EN parity checks, and record a material correction.

A new date does not make a claim accurate, while older material can remain valid. Freshness also guarantees neither ranking nor citation; it reduces the risk of stale facts, while usefulness, accessibility, and source selection remain separate questions.
