WS-5a commit 1 of 4 per ARCH-CONSOLIDATION-ADDENDUM-2026-04-24 Q3. Creates the relational home for what was form_fields.binding JSON and form_field_library.default_binding JSON. Owner discriminator is polymorphic morph (owner_type/owner_id) — the pattern the rest of WS-5 (5b validation_rules, 5d options) will reuse. Migration backfills rows from both JSON sources in a single transaction and is genuinely reversible (rollback reconstructs the JSON). Old columns remain in place until commit 3 has switched all readers. Pattern B (binding=null) is represented by absence of row. mode enum covers entity_owned / mirrored only. Cascade on owner delete via observer — bindings are physical state, not historical audit. FormFieldBindingScope enforces multi-tenancy via UNION over both owner chains (form_field → schema → org OR form_field_library → org) — Q2's declarative tenantScopeStrategy() can't walk morph parents. Tests: migration forward/back, morph relation, cascade observer, scope isolation, enum coverage. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
