Observation history · append-only
Tracking started:
Every row below is one observation of Haiper’s free tier, read on the provider’s own pages on the date shown. Observations are appended and never overwritten, so an older reading stays on this page even after the tracker moves on — the value of this record grows the longer tracking runs.
1 observation recorded for this tool. See the current spec sheet and sources.

The code under each date is the observation’s content hash: the tracked facts as read that day, in digest form. A later observation whose hash differs is what produces a change entry in the change log. An unverified field reads Unknown — see the methodology.
