Standards catalog

This is the canonical classification layer behind mule-lint's guides and executable rules. A standard states the engineering outcome; one or more rules provide automation for it. Agent skills should read these records instead of embedding a separate copy of the guidance.

Classification

• Vendor requirement identifies behavior directly required for correctness or security by the Mule runtime or a supported platform capability.
• Recommended practice is the project's reviewed default for reliable, maintainable Mule work.
• Opinionated convention improves consistency but may reasonably vary by organization.

The structured source includes applicability, status, source URLs, and a verification date. Read it through mule-lint://standards, then use mule-lint://standards/{id} and the linked guide for detail. Rule-to-standard mappings and profile membership are available from mule-lint://rules.
