GET /api/cma/alignment/tree queried all active KPIs without entity_id filter,
so switching the three alignment modes showed other tenants' KPIs.
Add get_entity_id dependency and filter KPIDefinition by entity_id.
Three mode builders (_build_vertical_tree/_build_horizontal_tree/_build_bsc_chain) unchanged.
Auth semantics unchanged; cross-entity explicit entity_id still returns 403.
Test: tests/test_alignment_entity_isolation_20260918.py (3 modes x both directions, 403, 401).
Root cause: main.py include_router had no global auth dependency; user routers
(products/cost/predict/...) relied on assert_entity_scope, which treats a
missing session token as the Bot service channel and lets the request through.
Result: 46 user endpoints returned data without any token on a public site.
Changes:
- auth_middleware.py: add require_auth_401 (missing Bearer -> 401, delegates to
require_auth otherwise); 401/403 semantics are explicit.
- router-level Depends(require_auth_401) on products, cost, predict,
notifications, permissions, tenant, alignment; endpoint-level on
/auth/roles and /admin/cache/clear.
- deps.py: document that get_entity_id/assert_entity_scope are NOT auth.
- frontend: add the missing Bearer header to 5 tokenless fetch/axios calls that
hit the newly protected endpoints (KPIAlignment x2, RolePermissions x2,
Dashboard x1).
- tests: new test_api_auth_surface_20260914.py (58 cases: no-token 401,
token 200, cross-entity 403, bot channel unchanged); adapt test_predict /
test_kpi_forecast to send session tokens like production.
- scripts/audit_api_auth_surface.py: reusable FastAPI dependency-graph audit
(423 endpoints; A bot / B gap / C public), exits 1 when a B-class gap exists.
