VideoAmp impressions check public producer templates.

Partial warning-only advice for the exact impression route shown by MetaRouter and PRX. Common template slots and supplied IP syntax are checked. MetaRouter mappings do not define universal receiver requiredness; opaque IDs, cachebuster values, custom fields, transport and duplicate selection remain open.

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
`url_id`	optional	The published impression route reserves a nonempty provisioned URL_ID path slot. Check only physical slot emptiness, without UUID, alphanumeric, account or equality claims. Presence diagnostic severity: warning.	`vendor.videoamp-impression.param.url_id.empty`	docs
`path_vpxid`	optional	The published impression route reserves a nonempty provisioned VPXID path slot. Query/form fields cannot fill this slot. Values and path/query consistency remain opaque. Presence diagnostic severity: warning.	`vendor.videoamp-impression.param.path_vpxid.empty`	docs
`vpxid`	recommended	The provisioned query ID appears in both published producer templates. Presence advice only: identifier grammar, empty values and equality with the opaque path slot remain unvalidated. Presence diagnostic severity: warning.	`vendor.videoamp-impression.param.vpxid.missing`	docs
`bwb`	recommended	Provisioned tag setting included in both producer templates. Presence advice does not infer numeric type, batch meaning, bounds or account validity. Presence diagnostic severity: warning.	`vendor.videoamp-impression.param.bwb.missing`	docs
`cb`	recommended	Both templates include a cachebuster slot. MetaRouter maps timestamp while PRX uses randomstr, so populated values stay opaque and no numeric, date or freshness rule is imposed. Presence diagnostic severity: warning.	`vendor.videoamp-impression.param.cb.missing`	docs
`ip`	optional	MetaRouter maps context.ip to an IP-address string. Check only submitted populated literals. IP absence is permitted: PRX requires separate data-sharing context, and MetaRouter matching advice is not universal receiver requiredness. Presence diagnostic severity: warning.	`vendor.videoamp-impression.param.ip.empty` `vendor.videoamp-impression.param.ip.invalid`	docs
