* 🟡 (23:01) Agent created branch `BYK/fix/stripe-projects-catalog-upgrade-path` tracking `origin/master` for the catalog allowed_updates fix (item #6)
* 🟡 (23:01) Agent confirmed `project` service had no `allowed_updates` — added paid plan tiers (team, business) as upgrade targets using typed `{service, direction}` format from APP spec
* 🟡 (23:01) Agent also updated plan `allowed_updates` to use typed format (spec requires single response to use one style consistently — either legacy `Set<string>` or typed objects, not both)
* 🟡 (23:02) Agent checked existing tests — no direct assertions on `allowed_updates` shape in test_endpoints.py; resource_update_service tests validate upgrade/downgrade behavior, not catalog shape
* 🟡 (23:03) Agent added 2 new tests to `test_endpoints.py`: `test_project_allowed_updates_include_paid_plans` and `test_plan_allowed_updates_are_typed_and_bidirectional`
* 🟡 (23:03) Lint (`prek run -q`) passed — all checks passed
* 🟡 (23:03) 3 targeted catalog tests passed: `test_paid_plans_expose_freeform_price`, `test_plan_allowed_updates_are_typed_and_bidirectional`, `test_project_allowed_updates_include_paid_plans` (84 collected, 81 deselected, 3 selected)
* 🟡 (23:04) Full stripe_projects test suite passed: 241 passed in 307.62s (5:07) — includes all resource_update_service upgrade/downgrade tests plus seer_redundant_rpc tests
