Scope and evidence
Evaluated on each in-scope origin. The book marks this requirement SEARCH-ENGINE-SPECIFIC.
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.
shadowed_rulesrobots.txt has a group for {token} (line {line}). {crawler} follows only that group, so these rules from the * group do not apply to it: {rules}. If they should, repeat them in the {token} group.
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.
