Measured from our own durable cache, not declared. Gated lanes train at full weight and can carry a claim; context lanes train at reduced weight and never can.

A lane can only carry a claim when a forecast is recorded before its outcome arrives, with the lead time declared. Observations alone train the shared representation and nothing more.
Below the entity floor or with too short a forecast era, a lane is context by construction — no threshold tuning can promote it after the fact.
Where a source went down mid-capture, the missing entities are counted and shown. A partial lane is labelled partial everywhere it appears.
