Understand what a check means
A finding references a validation rule. This lesson shows how our training reviewer reads that rule before deciding whether a correction or further investigation is needed. The catalogue groups checks by purpose, such as field format, row consistency and road-segment integrity. Its counts describe catalogue entries, not problems in your files. Use the finding's reference to locate its rule. Read its name, severity, description and active state before applying it to the example.
Check applicability
The rule detail identifies relevant file types and required fields. A rule can exist in the catalogue without being applicable to every template or export. A segment check needs meaningful start and end kilometre fields. If the source lacks the required information, the correct interpretation may be not checked. Distinguish a published-standard reference from an implementation rule or project-specific requirement. Do not claim the same authority for every kind of check.
Follow the reference
Read the cited section and explanation in context. A short rule summary is a guide to investigation, not permission to ignore the source definition. A disabled catalogue entry is not evidence that a submitted file passed it. Confirm the actual validation run and recorded coverage for that file. Use the rule's meaning to identify the source correction. Removing an error message without fixing its cause produces an unreliable review.
Read the rule and the recorded run
A range check requires meaningful start and end kilometre values. The training reversed interval illustrates why a rule must be read with its fields and applicability. Identify whether its basis is a published-standard reference, an implementation choice or a project requirement before describing its authority.
A disabled catalogue entry is not a passed check. Locate the current result, confirm that the required fields were available and read the finding examples. Correct the source cause rather than merely removing the message from view.
Practise and check your interpretation
Pause here. Find the sample finding's rule, identify its required fields and applicability, and explain why catalogue coverage differs from a particular validation run.
The reversed-range finding refers to TMH18§1.7/DQ-05. Read the rule’s applicability, field requirements and stated basis. A catalogue entry is not proof that a particular run executed it. A disabled rule, missing required field or unavailable reference cannot be interpreted as a pass. The supplied validation-results.json records the checks actually executed on the exercise files by this local source version.
