Bills were persisted correctly but read back wrong. The read path rebuilt a cart from its lines alone, dropping bill-level discounts and loyalty, so every figure derived from a stored bill was overstated: the upload payload, the day archive and the shift report. A discounted 529 bill read back as 620. Money and data integrity - order_dao: restore bill_discount and points_redeemed when rebuilding a cart; keep the reconstruction tier-less so the membership discount is not applied twice. Trust the recorded total and points via SaleTransaction.storedTotal. - checkout_sale + order_dao.commitSale: write the bill, its stock movement and the loyalty update in one transaction. Previously a failure part-way through left a persisted bill the cashier believed had failed, inviting a duplicate. - checkout_sale: re-check every line against live stock. A parked bill resumed after its stock was sold passed validation and oversold. - catalogue_dao: allocate the invoice sequence in one transaction; the previous read-modify-write could hand two sales the same number and fail UNIQUE. - local_store: replay unsynced sales after a catalogue import, so a mid-shift re-import cannot restore stock that has already been sold. - payment_controller: stamp the signed-in operator on the bill instead of the hardcoded seed session, and pass the terminal id through. - cart: reconcile per-slab GST against the bill total so the parts sum to the whole on a tax invoice. Sync and reporting - sync_repository: drain unsynced bills in a loop rather than silently capping at one page; stop on rejection so rejected rows cannot loop forever. - sync_log_dao (new): persist the sync history to the sync_log table, which the schema already defined but nothing used. It was in memory, so the only record that bills had been uploaded died at restart. - Scope shift reports by cashier. day_archive is re-keyed to (business_date, cashier_name) so a till stays settleable after its bills are uploaded and deleted. Schema v4 with a migration that carries v3 rows across. Input and UI - barcode_service: consume machine-paced keystrokes so a scan cannot also land in the focused field, and raise the bar to 60ms/char while a text field has focus so typing a mobile number is not read as a scan. Clock and focus check injected so the behaviour is testable. - primary_button: make the label flexible; label plus trailing total overflowed the Charge button by up to 131px. - app_router: redirect instead of null-casting when the receipt route is entered without its transaction. - customer_repository: reduce the search query to digits so a punctuated mobile number matches. Cleanup - Remove TransactionRepository.save, CustomerRepository.recordSale and OrderDao.insertOrder, all superseded by commitSale. - dart fix across the tree; 251 analyzer issues down to 3 info-level. Tests: 23 passing / 15 failing -> 90 passing. Fixed the two defects that broke the existing suite (containsAll type argument, reset() needing a catalogue) and deleted the leftover template test. Added coverage for the order round trip, the day archive after a real sync, stock safety, checkout atomicity, the v3->v4 migration, scanner-versus-human input, and an app-level smoke test that renders every module. Note: bills already uploaded with a discount went up overstated. This stops it happening again but does not correct historical server data. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
