Migrate legacy Salesforce UI stacks onto modern LWC — Aura → LWC conversion completeness verification and Lightning Out Beta → Lightning Out 2.0 host-page migration. TRIGGER on "verify Aura to LWC migration completeness", "migrate Lightning Out Beta to LO 2.0", "upgrade $Lightning.use() to <lightning-out-application>", "replace hardcoded LO tokens with OAuth PKCE", "write an LO 2.0 host page", or an external Lightning Out page that stopped rendering; also `.cmp`/`.js-meta.xml` files alongside LWC. DO NOT TRIGGER for the initial Aura-to-LWC conversion (use experience-aura-lwc-migrate), a React-to-LWC migration, or building a new LWC (use experience-lwc-design-generate).

# Migrating Legacy LWC Stacks

Two distinct migration workflows live here because users in the middle of
migrating Aura components are often also migrating Lightning Out host pages
— they benefit from one skill that knows both.

| Migration                          | Use when                                               | Reference                                                                                              |
