Replace raw db.execute tuple casts with queryRows/rowsFrom/execResult/
affectedRows helpers from lib/db, drop redundant mysql2 casts on typed
query builders, and centralize per-test fakeForm into test/fake-form.
Update db mocks in tests so helpers resolve against mocked execute.
The Arcturus errors "page hierarchy contains a cycle page 354 and 357" and
"sibling order 1 is used more than once (111 problems)" come from
catalog_pages, not catalog_items: pages 354/357 point at themselves, and
many parents have child pages sharing the same order_num. Extend the
emulator catalog scan + fix to detect both: pages whose parent chain loops
back get detached (parent_id = 0 on the highest cycle member) and every
affected parent's children are renumbered sequentially, preserving their
current relative order.
Add scripts/diag-emulator.ts to inspect the live catalog state.
Block invalid catalog_items writes at the API level (points currency
allowlist, non-negative prices, positive amount, limited stack >= sold
count, unique sibling order numbers) and auto-assign unique order numbers
on bulk create. Add a catalog-maintenance scan + transactional repair that
fixes pre-existing rows: resets unsupported points_type, clamps negative
costs, sets amount to 1, raises limited_stack, renumbers duplicate orders
and deletes offers with missing page/item references. Surface the issue
count and a fix button in the admin maintenance panel.
Also: add enabled/retired flag to clone sources, classify poster and
currency furniture in item-kind, and remove the obsolete update-Nitrov3.sh.
