Calibration
How complete real observation windows become model-ready.
#Complete-series gate
Calibration uses the minimum count across all configured symbols. This prevents a broad universe from appearing ready because only one asset has sufficient history.
#Unique source evidence
The database unique index uses agent ID, symbol, and source timestamp. Multiple application requests for the same upstream quote do not advance calibration.
#Rejected inputs
Null bid or ask, non-positive midpoint, stale source time, a source halt, a missing benchmark, and an API failure do not become valid observations.
