Thailand observation history.
This page shows what changed between persisted observation runs, not just the latest live ledger. Use it to audit refresh cadence, row churn, and graph-wide context changes over time.
Stored observation timeline.
This static page explains the observation-history model. The feed registry lists the sources and fields available to future persisted snapshots.
Observation history dashboard
Stored snapshots can supply a timeline and row-level differences when that service is connected.
No live history endpoint is attached to this static build.
The static feed registry remains available while live history is unavailable.
