Angular v22 Duplicate Selector Diagnostic Gate

Purpose

Resolve multiple directive/component selectors matching the same element when diagnostics flag ambiguity.

Keep the work concern-first: this skill handles one risk area and does not replace the Angular 21 to 22 hop orchestrator.

When to Use

• The task specifically involves resolve multiple directive/component selectors matching the same element when diagnostics flag ambiguity.
• The project is on Angular 22 or planning the Angular 22 hop.
• A narrower concern-first skill is better than a generic v22 baseline skill.

Do Not Use When

• The project version is unknown and the compatibility router has not run.
• The task is unrelated to this risk area.
• The user only needs a general Angular explanation.
