Scope and evidence
Evaluated on page (P). The book marks this requirement house convention. As a house convention it is off by default, carries no weight, and appears only when a team opts in.
Observations
Each condition has a stable code and a reason template. The evaluator fills the placeholders from observed values only; no sentence in a report is generated.
over_1mb{url} is {bytes} bytes uncompressed. Google's documented fetch limit is 2MB; the 1,000,000-byte warning is a house convention.
Sources, quoted
These are the passages the rule rests on, stored once in the knowledge base and emitted exactly as written. A citation marked for specific conditions appears only on findings with those codes.
