Field notes
The service describes preserving each original publication with a SHA-256 fingerprint, then matching node names across releases even when they change. Its API example identifies the date of the source snapshot and includes a disclaimer distinguishing mirrored data from an award of grid access. The page also shows audience-specific details, including 220 and 400 kV filters for data centers and monthly saturation history for investors.
