The role split was right; only its source was wrong. Signing in matched what
was typed against two constants compiled into the app — admin@nearle.in and
cashier@nearle.in — so which shell a person got was a property of the *build*.
A shop could not add a third person, revoke either of the two it had, or stop
anyone with the APK reading both passwords out of it.
TerminalLogin survives unchanged in shape, because the shape was the good part:
one flag the shell reads, a session that decides it, and a cashier sign-out that
takes the catalogue with it while a supervisor's leaves it behind. Every
consumer — visibleModulesProvider, resolvedModuleProvider, the sidebar, the page
header, the sign-out dialog — is untouched. What changed is that the enum is now
only constructible from a session the back office signed, so there is no path
left where the terminal grants itself a permission the server did not send.
It reads `can_manage_staff` rather than the role name or id. app_roles holds six
rows for four distinct roles, a great many accounts carry a roleid that is not
in the table at all, and the name comes back blank for most of them. Matching on
either would mean shipping a copy of the role table in the app and keeping the
two in step for ever. One boolean, decided server-side, cannot drift. It
defaults to false, which matters on the restore path: a session saved by a build
that predates the field comes back as a cashier, never silently as an admin.
This also restores the sign-in layer itself — pos_auth_api, pos_session,
session_store, the staff import and the bearer token — which an earlier commit
removed wholesale from a stale checkout. Its parent was the commit that added
them, so the deletion was a bad merge rather than a decision; the terminal has
been running on the two constants since.
The login screen loses its role tabs and its credential prefill. You do not
choose what you are on the way in.
The opener is now matched on the back office user id rather than on the first
account with a matching role, so the first bill of a shift is attributed to
whoever actually signed in.
Tests: the smoke suite pinned only the supervisor shell, and it was passing for
the wrong reason — the fake session omitted can_manage_staff, and the sidebar it
asserted on was there because the role was hardcoded. Both halves are pinned now
and the fake is parameterised. widget_test.dart was the stock Flutter counter
template, restored by the same bad merge, testing a MyApp that has never existed
in this repo.
292 tests pass; analyzer reports no errors and no warnings.

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.
