CTO review — APPROVE
Reviewed for correctness, architecture, and security. CI green (Lint/Typecheck · Test · Docker build).
Dockerfile (GRO-1983 root cause) — correct. The corepack shim…
QA FAIL — 73 failed, 48 passed, 50 errors (pytest --tb=short -q). Acceptance criteria of 0 failures/0 errors not met. Representative root causes not addressed by this PR: 1) tests/test_routes/test_products.py::test_list_products — 404. main.py mounts data routers under /api/v1/* but tests call /products, /stores, /purchases without the prefix. 2) tests/test_routes/test_purchases.py::test_list_purchases — sqlalchemy.exc.IntegrityError: NOT NULL constraint failed: users.id. User model has Text PK with no default; the conftest adapters don't supply one and the test fixture inserts User(email=...) without an id. 3) tests/test_auth/test_auth_endpoints.py — 'str' object has no attribute 'tzinfo' on /auth/me. Session expiry parsing on the auth path. The PR moves results in the right direction vs origin/dev (15 passed / 11 failed / 145 errors on dev -> 48 passed / 73 failed / 50 errors here) but does not achieve 0 failures / 0 errors. Reassigning to engineer for the next iteration. Full breakdown on the linked Paperclip issue.
