MNTN product images retain optional mapping values.

Mapped product price and image URL fields receive advisory checks. Empty and literal null values from the published sample remain valid. Product names and SKUs stay open.

Non-revenue conversions can omit order identity and amount. Page title, analytics IDs and custom metadata remain accepted. DOM mappings and cache-buster uniqueness require surrounding context.

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
`shaid`	required	The documented advertiser identity is required. It is usually numeric, so no numeric-only grammar is imposed.	`vendor.mntn-image.param.shaid.missing` `vendor.mntn-image.param.shaid.empty`	docs
`cb`	required	A nonempty cache-buster is required. The documentation permits arbitrary unique values.	`vendor.mntn-image.param.cb.missing` `vendor.mntn-image.param.cb.empty`	docs
`conv`	optional	The published conversion example uses 1. Zero is accepted as a page-view flag. Value diagnostic severity: warning.	`vendor.mntn-image.param.conv.empty` `vendor.mntn-image.param.conv.invalid`	docs
`plh`	optional	Optional absolute page URL, including iframe context.	`vendor.mntn-image.param.plh.empty` `vendor.mntn-image.param.plh.invalid`	docs
`shoid`	optional	Order or acquisition identity. The manual guide permits unmapped non-revenue conversions.		docs
`shoamt`	optional	A populated acquisition amount is numeric. The manual guide permits omission for non-revenue conversions.	`vendor.mntn-image.param.shoamt.empty` `vendor.mntn-image.param.shoamt.invalid`	docs
`shadditional`	optional	The image guide describes comma-separated key=value pairs. Custom names and values remain open. Value diagnostic severity: warning.	`vendor.mntn-image.param.shadditional.empty` `vendor.mntn-image.param.shadditional.invalid`	docs
`shpn`	optional	Optional mapped product name. The sample can stringify null. Presence diagnostic severity: warning. Evidence: vendor template.		docs
`shpp`	optional	Optional mapped product price or the sample null sentinel. Presence diagnostic severity: warning. Evidence: vendor template.	`vendor.mntn-image.param.shpp.empty` `vendor.mntn-image.param.shpp.invalid`	docs
`shps`	optional	Mapped SKU remains opaque caller data. Presence diagnostic severity: warning. Evidence: vendor template.		docs
`shpi`	optional	Optional mapped product image URL; the sample can stringify null. Applies when {"kind":"not","condition":{"kind":"value_in","param":"shpi","values":["null"]}}. Presence diagnostic severity: warning. Evidence: vendor template.	`vendor.mntn-image.param.shpi.empty` `vendor.mntn-image.param.shpi.invalid`	docs
`shpt`	optional	Optional page title from the published analytics snippet. Presence diagnostic severity: warning. Evidence: vendor template.		docs
`ga_tracking_id`	optional	Optional analytics identities may be a semicolon-separated list. Presence diagnostic severity: warning. Evidence: vendor template.		docs
`ga_client_id`	optional	Optional analytics client identity remains opaque. Presence diagnostic severity: warning. Evidence: vendor template.		docs
`method`	optional	Image tracking uses GET. Complete HTTP capture contract. Presence diagnostic severity: warning. Evidence: vendor template.	`vendor.mntn-image.http.method.empty` `vendor.mntn-image.http.method.invalid`	docs
