Three byte-identical copies of `normaliseLegacyGroupShape` lived in
FormFieldService, StoreFormFieldRequest, and UpdateFormFieldRequest.
WS-5d (form_fields.options) would have been the fourth copy. Hoist
the helper to a single public static on FormFieldConditionalLogicService
and have all three call sites delegate.
Implementation:
- `FormFieldConditionalLogicService::normaliseLegacyShape(array)` —
pure recursive passthrough. Translates the ARCH §8 JSON group shape
(`{"all": [...]}` / `{"any": [...]}`) into the service's internal
`{"operator", "children"}` form. Does NOT validate; malformed shapes
return as-is and surface downstream as
`InvalidConditionalLogicSpecException` from `assertSpecsValid`.
- Group operator catalogue sourced from
`FormFieldConditionalLogicGroupOperator::values()` instead of an
`['all', 'any']` literal — single source of truth for future
operator additions.
- All three call sites switched to the static method. The two
FormRequests reach it via the existing `use` import; FormFieldService
sits in the same namespace.
Behaviour preserved exactly:
- Existing FormFieldApiTest (cyclic logic rejection),
FormFieldStrictConditionalLogicRequestTest (strict-validator
rejection paths), and FormFieldConditionalLogicServiceTest
(service-level paths) all green without modification.
New unit tests pin the passthrough contract (8 tests):
- Valid ALL / ANY translations
- Recursive nested-group translation (depth 2)
- Internal shape unchanged
- Condition leaf passthrough
- Unknown group key (`xor`) returned unchanged for downstream
`assertSpecsValid` to reject
- Empty array unchanged
- Non-array children stripped silently
Tests: 1150 → 1158 green (3110 → 3124 assertions).

WS-5c commit 2 of 4 — the service layer, backfill migration, and
read-path switch. Per addendum Q3, conditional_logic applies to
FormField only — no library mirror and no copyLogic on
FormFieldService::insertFromLibrary.
FormFieldConditionalLogicService owns every write:
- logicFor(field): depth-limited eager-load of the tree
- replaceLogic(field, tree): transactional structure + operator +
field_slug validation + cycle check + activity-log emit
(field.conditional_logic_replaced)
- toJsonShape(root): reconstructs the canonical ARCH §8
`{show_when: {...}}` shape — single source of truth for the
snapshot writer + API resources
- assertSpecsValid(tree): public boundary guard for the FormRequest
strict validator (WS-5c commit 3 wires this up)
- assertNoCycles(field, tree): contract preserved from
FormFieldService::assertNoConditionalCycle, implementation now
reads the relational adjacency.
Backfill migration translates pre-WS-5c conditional_logic JSON to
rows. Strict dispatch: unknown operators / unknown top-level keys /
malformed groups FAIL the migration — Phase A seed-scan confirmed
the catalogue parity, so any drift is a data bug to fix at source,
not silently absorb. Rollback rebuilds canonical JSON and clears
the relational tree.
FormFieldService.create/update route `conditional_logic` through
the new service (matching the extract-and-delegate pattern from
WS-5a bindings and WS-5b validation rules). Snapshot writer + both
resources (FormFieldResource, PublicFormSchemaResource) read via
`toJsonShape(rootConditionalLogicGroup())` — byte-for-byte parity
with the pre-WS-5c JSON contract.
InvalidConditionalLogicSpecException handled in FormFieldController
as 422, same as FrozenSchemaException / CyclicDependencyException.
Tests: 20 new under tests/Feature/FormBuilder/ConditionalLogic/
(service, cycle detection, backfill forward+rollback+failure cases,
snapshot + resource parity). FormFieldApiTest cyclic rejection test
rewritten to use the new factory state. Rollback step counts in
WS-5a/b migration tests bumped +1 for the new backfill migration.
Baseline 1122 → 1142 green (3032 → 3085 assertions).
