xrtm-data

xrtm-data provides the temporal and schema foundations for the ecosystem.

Page role

This page is a package-map summary. Data-layer implementation details live in xrtm-org/data, while normative schema and compatibility policy live in xrtm-org/governance.

Use this package when​

  • you need snapshot-aware data access or replay foundations
  • you care about temporal integrity and zero-leakage evaluation
  • you are building lower-level data flows beneath the forecasting/runtime layers

What it gives you​

  • Vaulting: frozen world states with integrity checks
  • Historical replay: time-safe access to past context
  • Zero leakage enforcement: shared snapshot_time foundations used across the stack
