From d257d64925efdd223994315aee824127587251fa Mon Sep 17 00:00:00 2001 From: "bert.hausmans" Date: Sun, 26 Apr 2026 12:43:12 +0200 Subject: [PATCH] feat(form-builder): add PersonProvisioner with race-safe firstOrCreate (WS-6) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit PersonProvisioner reads bindings from schema_snapshot (RFC Q6) and provisions Persons via lockForUpdate + firstOrCreate (RFC Q8). Person is event-scoped (Person::$organisationScopeColumn = 'event_id'), so the lookup matches by (email, event_id) — cross-event submissions never collide. Throws PersonProvisioningException on misconfiguration (failsafe — publish guards should prevent these at config time): no_transaction, no_event, no_identity_key, identity_key_missing_value, no_crowd_type. Snapshot enrichment: FormFieldBindingService::toApplicatorShape + FormSubmissionService snapshot now adds a 'bindings' (plural) key with binding id, merge_strategy, trust_level, is_identity_key. Singular 'binding' key kept for legacy webhook / GDPR readers. Includes RFC V4 state-injection concurrency test asserting recovery semantics under lockForUpdate windows.
