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
`ti`	required	It is the numeric UET tag ID. Microsoft documents how to create and install the tag but not the request format, so this rule is ecosystem evidence. Fix: Copy the UET tag ID from Microsoft Advertising into the tag snippet.	`vendor.microsoft-uet.param.ti.missing` `vendor.microsoft-uet.param.ti.empty` `vendor.microsoft-uet.param.ti.invalid`	docs
`Ver`	optional	It is the UET tag version the snippet reports.	`vendor.microsoft-uet.param.Ver.empty` `vendor.microsoft-uet.param.Ver.invalid`	docs
`evt`	optional	It names the event, such as a page load or a custom event.	`vendor.microsoft-uet.param.evt.empty`	docs
