fluentform-submission-lifecycle

Implements and audits Fluent Forms server-side submission behavior from parsed field data through sanitization, validation, persistence, entry details, notifications, integrations, and confirmation. Selects the correct fluentform/input_data_*, fluentform/validation_errors, fluentform/insert_response_data, fluentform/submission_inserted, and fluentform/submission_confirmation hook and explains their timing. Use when adding cross-field validation, normalizing submitted values, reacting to an entry, debugging missing submission data, preventing duplicate side effects, or distinguishing a Pro partial draft from a completed submission.
