Sato Score, daily

2026-06-11 → 2026-10-29

4 days in this span have no reading; the line breaks there rather than joining across them. A dashed vertical mark (┆) is a day Sato Hub changed the scoring method — movement on those days is ours, not the project’s.

Every day the score moved

2 changes attributable to the project, 2 caused by a revision of the scoring method.

What moved, component by component

Six charts, six axes — each scaled to its own maximum weight. They are never stacked on one axis: a component worth 10 points and one worth 35 would not be comparable on a shared scale, and the small one is usually the one that moved.

The observed record

100% of 108 daily checks since 2026-07-14 succeeded. This is the share of OUR checks that succeeded. It is not uptime: a failed check can be on our side. When a check before 2026-09-01 failed, the checks before that date are left out of the rate: the probe counted a bot-block as a failure then and recorded no reason for any failure.

What happened alongside it

Releases, status changes, applied corrections and answered disputes, on the same dates — so a movement in the line can be read against an event rather than guessed at.

How to read this

· Every point is one UTC day. A day we did not capture is drawn as a gap, never joined across.
· A change on a marked methodology day is ours, not the project’s.
· The score says how open, active and verifiable the project is. It is not a safety, quality or returns grade.
· The inputs behind today’s score are published at /api/export/score-inputs.json and the arithmetic is reproducible on your own machine.
