From 10b5d4e9b03af4057a7e8b7eaf28a45a5a975c54 Mon Sep 17 00:00:00 2001 From: Michael Chihlas Date: Thu, 28 May 2026 16:07:23 -0400 Subject: [PATCH] docs(l1): Phase 1 acceptance validation report MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Full backend suite (1325/1325 passing, xdist) + L1-specific tests (57/57) + L1 RLS tests (8/8) + frontend build (tsc clean, vite clean) + migration roundtrip results. Per-line checklist against spec §15. Known Phase 2/3 items explicitly deferred per plan scope section. fix(test): RLS fixture users INSERT missing NOT NULL columns test_l1_rls.py and test_rls_isolation.py seeded users without the five NOT NULL columns added in prior migrations (is_super_admin, is_team_admin, is_service_account, must_change_password, timezone). Also adds DROP SCHEMA before alembic upgrade in _ensure_rls_schema to prevent DuplicateTable errors when create_all tables are present.

Unexpected findings during validation + +1. **RLS test fixture bug** (fixed in this commit): `test_l1_rls.py` and `test_rls_isolation.py` both had users INSERT statements missing five NOT NULL columns (`is_super_admin`, `is_team_admin`, `is_service_account`, `must_change_password`, `timezone`) added by earlier migrations. The `_ensure_rls_schema` fixture also lacked a schema DROP before the alembic upgrade, causing `DuplicateTable` errors when `Base.metadata.create_all` tables were present from prior test runs. Both fixed in this commit. + +2. **Test isolation is xdist-dependent** (pre-existing, not introduced by L1): The `test_db` fixture drops and recreates the public schema per test function. Without xdist worker isolation, sequential tests in the same process see `UndefinedTableError` after the first test's teardown runs. This matches the known behavior documented in commit `7f71436` (perf/ci). CI uses xdist; local single-module runs work; full-suite single-process runs fail. Not a defect in Phase 1. + +3. **Migration downgrade on seeded DB** (expected): `alembic downgrade -7` fails when `l1_tech` users exist in the test DB — the old CHECK constraint excludes `'l1_tech'`. This is correct behavior; downgrade scripts assume a fresh DB. The plain upgrade path from empty schema is clean. + +--- + +*Report generated by T26 acceptance validation pass, 2026-05-28.*
