myco-migrate-domain-field-symmetry

Use when migrating an existing UniFi resource domain to the shared field-symmetry model — even if the user doesn't explicitly ask for "field symmetry." Covers the full migration procedure: auditing list/create/update field parity gaps, creating models/<domain>.py with DomainBase + submodels, implementing field validation, and ensuring field symmetry compliance. Enforces the critical ResourceValidator safety constraint: shared validator defaults are forbidden (blast-radius anti-pattern). Reference implementation patterns established in Phase 4 (May 2026). All three servers (Network, Protect, Access) now use this pattern.
