Every day in this span has a reading. 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 Sato Hub's own daily checks succeeded over 57 checks. This is the share of OUR checks that succeeded. It is not uptime: a failed check can be on our side, and before 2026-09-01 no failure recorded why.

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.
