Platform limitations

View counts are not exposed because the platform hides them. Missing metrics are not zero.

The 30d search filter falls back to all with a warning.

Product and commerce data are outside the six core verbs.

Share-link resolution is separate from the observed core supply evidence; prefer a stable public note URL or ID.

Native 1d/7d search filters can return older content. When returned dates are older than the requested window, that page reports time_range=all with a warning. Items are preserved and no extra search is made; missing dates remain unverifiable.
