Scope and evidence
Evaluated on pages in P with annotations. The book marks this requirement .
No source assigns a separate consequence; Google ignores annotations that are not reciprocated (SEO-I18N-02).
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.
target_not_200{url} names {target} ({code}), which returned {outcome}.
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.
