description	Plan and execute migration from Avalonia 11.3.12 to Avalonia 12 using the repository's dedicated migration lane. Use for breaking-change review, source-backed API delta lookup, migration sequencing, and upgrades that should stay grounded in the current published Avalonia 12 documentation and generated artifacts.

Avalonia 12 Migration

Start with:

• ../../references/68-avalonia-12-migration-guide.md
• ../../references/69-avalonia-12-breaking-changes-and-new-api-catalog.md
• ../../references/api-index-12.0.0-rc1-generated.md

Use the stable lane for current implementation guidance unless the request explicitly targets this migration.

Workflow

1. Confirm the source app is on Avalonia 11.3.12 or note the actual starting point.
2. Read the curated migration guide before touching code so sequencing is correct.
3. Use the breaking-change catalog for exhaustive impact review and the generated Avalonia 12 index for signature lookup.
4. Call out current published Avalonia 12 status explicitly when making recommendations.

Rules

• Keep migration guidance grounded in the current published 12.0.0* lane tracked by this repo.
• Do not let Avalonia 12 advice leak back into the default 11.3.12 skills.
• Separate required break fixes from optional modernizations.
