Artsai impression templates receive field advice.

Partial warning-only advice for the tag=imp1 impression profile published by PRX and ART19. Common template slots and supplied IP syntax are checked. PRX-only context, ART19 headers, identifier formats, opaque message contents and receiver-wide requiredness 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
`ad_log`	recommended	Both published impression templates include this provisioned account/tag slot. This is template completeness advice, with no identifier alphabet, grammar, token parsing or receiver-requiredness claim. Presence diagnostic severity: warning. Fix: Compare with the provisioned tag and the cited producer template. Other integrations can intentionally differ.	`vendor.artsai-impression.param.ad_log.missing`	docs
`msg`	recommended	Both published impression templates include this provisioned message slot. This is template completeness advice, with no identifier alphabet, grammar, token parsing or receiver-requiredness claim. Presence diagnostic severity: warning. Fix: Compare with the provisioned tag and the cited producer template. Other integrations can intentionally differ.	`vendor.artsai-impression.param.msg.missing`	docs
`pixid`	recommended	Both published impression templates include this provisioned pixel identifier slot. This is template completeness advice, with no identifier alphabet, grammar, token parsing or receiver-requiredness claim. Presence diagnostic severity: warning. Fix: Compare with the provisioned tag and the cited producer template. Other integrations can intentionally differ.	`vendor.artsai-impression.param.pixid.missing`	docs
`ip`	optional	PRX maps its IP-address macro into this query slot. Check supplied populated literals only. ART19 forwards IP through headers instead, so query absence and empty template slots remain accepted. Presence diagnostic severity: warning. Fix: Compare the supplied value with the original integration tag. Preserve consent-driven omissions and do not substitute a header chain into a single-address query slot.	`vendor.artsai-impression.param.ip.empty` `vendor.artsai-impression.param.ip.invalid`	docs
