// task_requirements.type IS a real DB enum (task_requirement_type), despite
// 20260709000001-add-requires-review-and-prompt-to-task-requirements.js's comment
// claiming otherwise ("Sequelize enforces the ENUM only at the application layer
// for this table, so no constraint migration is needed") — that assumption was
// wrong. submit_text and pass_quiz were added to the Sequelize model (task.mdl.js)
// and the admin RequirementBuilder.jsx UI at the same time, but never to the actual
// DB enum, so creating/querying either type has been failing with
// "invalid input value for enum task_requirement_type" ever since (found while
// verifying the new completion_requirements feature's task auto-complete path,
// which happened to be the first thing to actually query a pass_quiz-typed
// TaskRequirement against this DB).
//
// ALTER TYPE ... ADD VALUE (not CREATE TYPE) is a plain top-level statement, not
// wrapped in Sequelize's problematic DO $$...$$ block, so this runs fine as a
// normal migration — no raw-SQL-outside-migrations workaround needed here.
