-- Drop job_applications_screened_consistent
--
-- A defect in migration 000001. The constraint reads:
--
--   status = 'applied' OR screened_at IS NOT NULL OR ai_score = 0
--
-- which asserts that a screened application records *when* it was screened.
-- The frontend makes no such promise: `screened_at` is never read and never
-- written anywhere in the repository, and none of the 24 seeded applications
-- carries it. The column and the constraint both came out of the backend
-- blueprint rather than out of repository evidence.
--
-- The effect was that 9 of 24 seeded applications were rejected — exactly the
-- 9 AI-scored ones behind the "9 scored, averaging 76" regression anchor.
--
-- 000001 is already applied and is immutable, so the fix lands here. All 52
-- other CHECK constraints from 000001 were verified against all 245 seeded
-- records and hold.
--
-- The `screened_at` column is kept: it is nullable and unused, and removing it
-- is a separate cleanup rather than part of this fix.
