Return JSON from any uncaught engine exception, stop the empty stock-out warehouse list aborting page boot, reject non-transfer rows in the transfer lookup, define the missing reset_input helper, and remove a stale unreferenced copy of confirm_order.php.
Apply the configured timezone to PHP and both DB connections, wrap
unwrapped ajax payloads so delete buttons reach their engines, normalise
and validate invoice due dates, reject stock quantities below the stored
4dp scale, and list stock movements across all warehouses.
Stock Transfer list showed 0.00 (read in instead of out); stock-out/transfer forms show the location quantity; dates display as YYYY-MM-DD HH:mm:ss. Demo seeds map product accounts and use product names and supplier batches.
