CM360 VAST event pixels need dc_oe

Campaign Manager writes dc_oe into exported VAST. Google does not publish a table for it. Generated tags always include it, so an empty or missing value is a truncated export. eid1 is observed and not required. GAM pagead/interaction hops are not this pack.

Rules

Codes are stable. A finding in CI, MCP, or the playground lands on the same id.

Field	Required	What it checks	Rule ids	Source
`dc_oe`	required	It is the event payload Campaign Manager writes into exported VAST. Google does not publish a table for dc_oe; generated tags always include it, so an empty or missing value is a truncated export. eid1 is not contracted. Fix: Export the VAST tag again from Campaign Manager 360 so dc_oe is present and non-empty.	`vendor.cm360-vast-event.param.dc_oe.missing` `vendor.cm360-vast-event.param.dc_oe.empty`	docs
