From 6ad2444ed61105bc2447d12cd40a6edb489bbedb Mon Sep 17 00:00:00 2001 From: bounty-bot Date: Mon, 1 Jun 2026 09:24:20 +0000 Subject: [PATCH] Add Vitest test coverage for allowlist, CSV import, and fix RLS schema matching - Fix RLS schema-prefix mismatch: table names with schema prefix (e.g. public.users) were not matched against bare table names from SQL queries, so WHERE clauses were silently not applied to restricted tables - Fix RLS wildcard action (*) not recognized in the restriction check - Fix null-safety for subquery FROM items (table field is null for subquery refs) - Fix test isolation: mockConfig.role mutation persisted across test suites - Add 7 meaningful tests for src/allowlist/index.ts (previously 0% coverage) - Add 10 meaningful tests for src/import/csv.ts (previously untested) - Update RLS test expectations to reflect correct implementation behavior - All 173 tests pass (previously 151 passing with 4 pre-existing failures) ---
