The Observatory.
A public, continuous watch on the structure of the API surfaces the industry runs on. Measured every day since July 8, 2026. Values never collected. Nothing invented.
Confirmed contract drift recorded so far: zero.
That number is the point. A drift ledger you can trust is one that reports nothing when nothing happened. When a watched surface genuinely changes shape, the change appears here, with structural evidence, and the zero above becomes a record.
Watched surfaces.
Every provider below is observed daily through its public, poll-friendly endpoints. Each page is that provider's standing record.
Status pages

How this is measured.
Every day, the observatory requests each endpoint once and reduces the response to its structure: field names, types, and shape. The values themselves are discarded at the edge and never stored, which is the same discipline the ShiftGraph product enforces on customer traffic. All endpoints are public, unauthenticated, and built to be polled; most are status pages and registries that exist for exactly this.
A change only enters the record when the engine confirms sustained structural displacement, not variance. Live data moves constantly; incident lists grow and shrink, exchange rates update, counters count. In its first days the engine flagged 14 such dynamic-content changes on 8 endpoints as drift. They were not drift. We rebuilt the temporal gating so variance is recognized as variance, and every sweep since July 11, 2026 has run clean. That correction is part of this record because an early-warning system that cannot admit a false alarm cannot be trusted about a real one.
Alongside the ledger, 8 calibration endpoints (deliberately simple public APIs) exercise the engine daily and stay off the provider list. The snapshot behind this page was generated on July 14, 2026, covering 9 sweeps and 564 observations.
This is what we do for your dependencies.
The observatory watches public surfaces. ShiftGraph watches the APIs your product actually depends on, with the same structure-only discipline.
