-- regression_test_v15.sql — TDD tests 53-72 for pg_vault_tde v1.5
--
-- These tests are WRITTEN FIRST (Test-Driven Development).
-- They MUST FAIL on v1.4 and PASS on v1.5.
--
-- Each test block:
--   - Documents the feature being tested
--   - Documents the expected pass/fail boundary
--   - Uses ONLY public SQL API (no C internals)
--
-- Run sequence:
--   psql -f sql/pg_vault_tde--1.0.sql   (base install)
--   psql -f sql/pg_vault_tde--1.4--1.5.sql  (upgrade)
--   psql -f sql/regression_test.sql     (v1.4 tests 1-52)
--   psql -f sql/regression_test_v15.sql (v1.5 tests 53-72)
--
-- Exit-on-error: any failed assertion aborts the script.
