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.

- PurposeRegistryTest: all seven purposes load with expected shape;
`get()` throws PurposeNotFoundException on unknown slug;
`allSubjectTypes()` returns exactly [artist, company, person, user];
`publicAccessibleSlugs()` is only `[event_registration]`.
- PurposeSchemaLifecycleTest: data-provider-driven create → publish
for all seven purposes; negative tests for event_registration (three
missing bindings) and supplier_intake (company.name missing); partial
binding test reports only the missing subset.
- CustomPurposeEscapeRemovedTest: column gone, config file gone,
FormPurpose::CUSTOM gone, store endpoint rejects `'custom'`, resource
payload omits the field.
- SubjectTypeRegistryConsolidationTest: submission validation accepts
registry subject types, rejects everything else including the legacy
`event` alias that used to be allowed.
- MorphMapAlignmentTest: compile-time guard that every
PurposeRegistry::allSubjectTypes() alias appears in the morph-map and
in AppServiceProvider::PURPOSE_SUBJECT_FQCN.
- FormPurposeTest rewritten to cover the seven v1.0 cases and the
registry-delegation helpers (now extends Tests\TestCase for the
container).
- Public/listener tests swap the removed PUBLIC_RSVP / PUBLIC_COMPLAINT
/ FEEDBACK references for valid v1.0 purposes, preserving their
negative-path assertions.

9 backed string enums covering purpose, field type, submission status/mode/review,
field width, value storage hint, snapshot mode, webhook delivery status.
FormPurpose/FormFieldType include helper methods per ARCH §3/§5. All with
declare(strict_types=1) and values() helpers for validation rules.
