# 0002: Usage data always carries provenance
|
|
|
|
Status: accepted for the architecture phase.
|
|
|
|
Provider quotas and subscription windows do not share a stable universal API.
|
|
Lumbridge therefore stores observations with their source and derives forecasts
|
|
without overwriting the facts.
|
|
|
|
Allowed provenance values begin as provider-reported, harness-reported, locally
|
|
measured, estimated, and unavailable. The UI may simplify these labels in compact
|
|
views, but the detail view and export retain them.
|
|
|
|
Lumbridge will not scrape browser cookies, copy upstream OAuth tokens, or label a
|
|
local estimate as an exact remaining subscription balance.
