Top Mail.ru counters check published producer fields.

Advisory profile for the published Top Mail.ru page-view producer and its noscript counter. Numeric identity follows the help guide. Age and gender checks apply only to the pinned SDK js=13 profile. Receiver acceptance and other Mail.ru transports remain unverified.

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`	recommended	The producer serializes the configured numeric counter identifier. Presence diagnostic severity: warning. Evidence: vendor template.	`vendor.top-mail-counter.param.id.missing` `vendor.top-mail-counter.param.id.empty` `vendor.top-mail-counter.param.id.invalid`	docs
`js`	optional	Only the pinned js=13 profile enables producer-specific demographic checks.		docs
`age`	optional	The pinned producer retains integer ages from 1 through 127. Applies when {"kind":"value_in","param":"js","values":["13"]}. Presence diagnostic severity: warning. Minimum numeric value: 1. Maximum numeric value: 127.	`vendor.top-mail-counter.param.age.empty` `vendor.top-mail-counter.param.age.invalid`	docs
`gender`	optional	The pinned producer retains these two codes; this is a transport profile. Applies when {"kind":"value_in","param":"js","values":["13"]}. Presence diagnostic severity: warning.	`vendor.top-mail-counter.param.gender.empty` `vendor.top-mail-counter.param.gender.invalid`	docs
