Active View measurements allow nonmeasurable size and position values.

The published Active View pixel describes ad keys and measurement fields on pagead2 /pcs/activeview. The pack checks their observable syntax and dimensions.

Negative size and position values can describe a nonmeasurable impression. Viewability thresholds and timing correlations need browser and session context.

Apply the contracts within their published source scope.

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
`id`	optional	Measurement ID. The source shows osdim, lidar and lidarv without an exhaustive accepted set.	`vendor.google-activeview.param.id.empty`	docs
`adk`	optional	Opaque slot identifier used to correlate with the ad request. Numeric spelling is an example, not an explicit accepted grammar.	`vendor.google-activeview.param.adk.empty`	docs
`bs`	optional	Browser viewport width,height. Negative dimensions are explicitly valid diagnostics.	`vendor.google-activeview.param.bs.empty` `vendor.google-activeview.param.bs.invalid`	docs
`mtos`	optional	The published list has five coverage buckets, in order100%,75to99%,50to74%,25to49%,1to24%. Do not infer positivity or monotonicity from examples.	`vendor.google-activeview.param.mtos.empty` `vendor.google-activeview.param.mtos.invalid`	docs
`p`	optional	Four creative coordinates, top,left,bottom,right. Negative and zero-size rectangles are diagnostics, not malformed input.	`vendor.google-activeview.param.p.empty` `vendor.google-activeview.param.p.invalid`	docs
