Quora dwell events carry duration and lifecycle context.

Quora sends positive dwell milliseconds with a lifecycle reason such as blur or pagehide. The reason is a string. Optional Instant Article and GET checks follow the pinned SDK.

Custom event names, caller conversion strings and opaque event and click IDs remain open. These advisory browser checks do not borrow the Conversions API schema.

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
`pixel_id`	recommended	The producer places its configured pixel identity in this path segment. It does not enforce a UUID grammar. Presence diagnostic severity: warning.	`vendor.quora-pixel.param.pixel_id.missing` `vendor.quora-pixel.param.pixel_id.empty`	docs
`tag`	recommended	The event name is carried in tag. Custom names remain accepted. Presence diagnostic severity: warning.	`vendor.quora-pixel.param.tag.missing` `vendor.quora-pixel.param.tag.empty`	docs
`j`	optional	The JavaScript producer emits 1. Noscript calls are not required to supply this marker. Presence diagnostic severity: warning.	`vendor.quora-pixel.param.j.empty` `vendor.quora-pixel.param.j.invalid`	docs
`ts`	optional	The JavaScript producer emits a decimal millisecond clock value. No freshness window is inferred. Presence diagnostic severity: warning.	`vendor.quora-pixel.param.ts.empty` `vendor.quora-pixel.param.ts.invalid`	docs
`em`	optional	The pinned SDK accepts 64 case-insensitive alphanumeric characters as prehashed email. This check mirrors that profile without asserting digest correctness. Presence diagnostic severity: warning.	`vendor.quora-pixel.param.em.empty` `vendor.quora-pixel.param.em.invalid`	docs
`u`	optional	Optional page location from the producer. Presence diagnostic severity: warning.	`vendor.quora-pixel.param.u.empty` `vendor.quora-pixel.param.u.invalid`	docs
`v`	optional	The SDK permits string or numeric conversion values, including empty strings. No closed numeric grammar is imposed.	`vendor.quora-pixel.param.v.empty`	docs
`i`	optional	Optional event source string; its values remain open.	`vendor.quora-pixel.param.i.empty`	docs
`evid`	optional	Optional caller event identifier. Its format is not restricted by the SDK.	`vendor.quora-pixel.param.evid.empty`	docs
`dwt`	optional	Positive wall-clock dwell duration in milliseconds, emitted on DwellTime. Presence diagnostic severity: warning. Evidence: vendor template. Minimum numeric value: 1.	`vendor.quora-pixel.param.dwt.empty` `vendor.quora-pixel.param.dwt.invalid`	docs
`ive`	optional	Lifecycle reason passed by the timer. It is a string, not a Boolean. Presence diagnostic severity: warning. Evidence: vendor template.	`vendor.quora-pixel.param.ive.empty` `vendor.quora-pixel.param.ive.invalid`	docs
`fbia`	optional	FB Instant Article marker emitted as 1. Presence diagnostic severity: warning. Evidence: vendor template.	`vendor.quora-pixel.param.fbia.empty` `vendor.quora-pixel.param.fbia.invalid`	docs
`qclid`	optional	Opaque click identifier retained from the landing URL. Presence diagnostic severity: warning. Evidence: vendor template.		docs
`method`	recommended	Pinned browser collector transport. Complete HTTP capture contract. Presence diagnostic severity: warning. Evidence: vendor template.	`vendor.quora-pixel.http.method.missing` `vendor.quora-pixel.http.method.empty` `vendor.quora-pixel.http.method.invalid`	docs
