What it covers

The plugin provides domain-specific review guidance for patches touching:

• browser/components/asrouter/
• browser/components/aboutwelcome/

• Related test, schema, localization, and documentation files

It flags common pitfalls (e.g., missing make-schemas.py regeneration, cached DB connections, incorrect JEXL casing) and includes campaign-specific checks for active migrations.
